Standard parking sensors for Lada Granta sedan

A parking sensor, also known as parking sensors, is installed as standard equipment on the Lada Granta Liftback in the Luxury Premier configuration. Previous modifications do not have this bonus.

You can install parking sensors on the Granta Liftback (hereinafter referred to as DP) yourself; the installation work is not complicated. The main thing is to follow the instructions and avoid haste.

We will tell you further about how to professionally install the DP on the Lada Granta Liftback.

How to install parking sensors on a Lada Granta with your own hands in a sedan or liftback body

A modern and common option is parking sensors. It is responsible for determining the distance from the vehicle to the nearest obstacles. Not all cars are equipped with this element, so many add it themselves. Installing parking sensors on Grant involves the use of various tools and consumables.

Original equipment

There is a wide range of products on the market, but the equipment is not always of the required quality. Several system options can be installed on the Lada Granta; standard parking sensors are characterized by the following features:

The sensors are located in the front and rear bumpers.
The signal goes to the controller and converter, which creates the signal. Based on the frequency of the signal, you can determine the degree of proximity to the object.

The original device costs much more, but is highly accurate. There are also Chinese sensors on sale that also cope with the task.

General questions about body kit 2190

Let's answer a couple of basic questions about Granta bumpers.

Differences between sedan and liftback bumpers

The principle of working with front and rear bumpers on a sedan and a liftback is the same! There are no fundamental differences.

Why you may need to replace the bumper

Possible reason for replacing the body kit on a VAZ 2190:

Minor (or major) accident;
Installation of a non-original body kit;
Installation of additional devices: emergency parking sensors, rear view camera, etc.;
Curiosity.

There are many options for non-standard body kits for Lada today.

Non-native body kits are made unofficially. This can lead to problems with joints and color mismatches.

Where to find the front bumper amplifier

Unlike pre-restyling Kalinas, Grant comes with a bumper reinforcement from the factory . Many people confuse it with a regular mount. You will gain access to the part only after dismantling the front body kit.

The amplifier on the Lada is rather symbolic, like the factory crankcase protection. But there is no such thing on Kalina.

What to replace with

If the car is not equipped with a device to simplify maneuvering during parking, you can install parking sensors on the Lada Granta liftback yourself.

There are a large number of different devices available in Chinese online stores.

The main selection criteria are:

Sensing distance range. In most cases 0.3-2 m.
The voltage required to power the device is 9-12 V. Therefore, power can be supplied from various electrical elements of the vehicle.
Operating temperature (varies within -35…+45°C).
Sound signal with volume up to 80 dB.
The presence of a housing with protection from environmental influences.
Installing a display that shows the location of the sensor.

The Chinese Myhung driver can be downloaded on the Internet and is also included in the package.

Market Review

Sho-me offers inexpensive devices equipped with cameras. The manufacturer also has talking parking sensors.

Parkmaster BS6651 is an excellent and quite expensive device that is not only equipped with a camera, but can also project the trajectory of the car.

CRS 9701 is an affordable model with high-quality screen resolution. It makes it very easy to assess the situation in the rear.

Masterspark 2-8 – the device displays the image from the camera on the monitor and also produces sound signals.

How to install and connect

You can install parking sensors yourself. The instructions look like this:

The sensors are placed in the bumper. It is recommended to install 4 sensors front and rear.
For convenient work, it is recommended to dismantle the front and rear bumpers. Otherwise, you won’t be able to get high-quality holes.
After dismantling the bumper, masking tape is applied. It is required in order to carry out correct markings and eliminate the possibility of damage to the paintwork.
The recommended sensor placement height is 50-60 cm above ground level. The optimal distance between individual elements is 1/3 of the length.
The surface is being marked. This requires measuring instruments and a pencil. The quality of the result depends on the correct marking, so you need to be careful.
Appropriate holes are required to position the sensors. They can be obtained by drilling when selecting a suitable nozzle. When working, you need to be careful, because a mistake can cause damage to the bumper.
Once the holes are created, the masking tape is removed and the edges are cleaned. To do this, you can use a knife and needle files.
The wire passing through to connect the sensor is lowered into the hole. It is placed so that it is slightly recessed into the hole. If necessary, you can press on the sensor ears with a sharp object; a tight fit ensures long-term operation.
All sensors must be positioned strictly horizontally. Many manufacturers mark the housing with a corresponding arrow, which simplifies installation. If the device is pointed at the ground, it can be triggered by the ground. Fastening is carried out using special glue and silicone.
Secure the control unit in the luggage compartment. It is recommended to create a special sealed box for it, which will protect the main elements from environmental influences. The wires are routed through a standard rubber seal; additional insulation is provided to eliminate the possibility of damage.
From the front bumper the wires are routed backwards. To do this, they are located under the casing or plastic protection.

After this, the bumper is installed in place and the entire system is tested. The instructions are as follows:

Maneuvering is carried out in the courtyard; it is not recommended to immediately drive onto a public road.
The vehicle should be approached at different angles towards obstacles. Mistakes made can cause dead zones to appear.
When the system is activated, you should stop the car and check the distance.

At first, you have to get used to the way the parking sensors work. When installing it yourself, you have the opportunity to carry out subsequent repairs and maintenance.

Malfunctions and their elimination

Most often the problem is poor contact. High humidity causes corrosion. Repair consists of removing the oxide mechanically. If the integrity of the main elements is damaged, they will have to be replaced.

Preparing for installation

To ensure that nothing gets in the way during work, we take out everything unnecessary from the trunk.
We unscrew the plastic thumb at the right headlight protection, disconnect the wires going to it and disassemble the lamp.

Unscrew the lamb (photo of the editorial car)

Before drilling holes in the bumper, we check the functionality of all devices in place. Especially if you ordered parking sensors from Uncle LYAO through AliExpress.

To do this, connect (solder) the red parking sensor power wire to the reverse power supply track. We connect the ground wire to the body or to the flashlight wiring block. Next, turn on reverse gear and ignition.

You can see how in the photo the red wire is soldered to the reverse power track.

After this, we check the functionality of all sensors and the display.

Tools for work

In order to install parking sensors, you will need the following tools:

Parktronic.
Insulating tape.
Soldering iron.
Additional wires.
Milling cutter.
Screwdriver.
Pliers.
Double sided tape.
Masking tape.
Marker.
Steel wire.

Step-by-step process for installing parking sensors

First of all, we mark the cutout locations on the bumper for the touch sensors, having previously marked the areas at a distance of 50-60 centimeters from the ground .
For convenience and practicality, we stick masking tape on the bumper and draw the markings directly on it. Since you are working on the rear bumper, you can also attach the towbar!
Using a cutter, cut holes at symmetrically equal distances. This way you will get 4 holes located approximately 40 centimeters .

We cut the hole using a cutter and clean the edges using a file or needle file.

It is best to use wire that is both strong and flexible.

It is best to fix the block using 3M type double-sided tape.

This is what the parking sensor looks like after installation is complete.

What is parking sensors in a car?

The vast majority of modern motorists prefer this useful device. Very often, especially novice drivers, have difficulty parking their car. They struggle with anxiety and fear of harming their own or a nearby car, and all these worries are in vain if they have equipped their car with parking sensors.

Parking sensors are designed to help motorists in the most inconvenient and difficult situations - for example, when you need to park with your back to a wall or another car and there is no way to visually assess the distance to an obstacle. By installing parking sensors in your car, you will greatly facilitate the process of parking, even in the most inconvenient places, you will be able to protect your car from accidental damage, and yourself from waste associated with such troubles. Therefore, many people prefer the parking sensors comfortable parking system and know what it is firsthand.

A parking radar, or an acoustic parking system (APS), is installed to provide easier maneuvering and avoid collisions while parking and driving the vehicle. The “smart” system is able to recognize all objects that are in an area poorly visible to the driver, and those that are completely impossible to see from the driver’s seat. The system notifies the driver through sounds and/or graphics that the vehicle is approaching an obstacle, and the alerted driver performs the necessary maneuvers to avoid a collision.

The first parking sensors were equipped with high-class cars of very popular brands. This new invention immediately received positive responses from owners of expensive cars and became very popular. Now, thanks to large-scale production, parking sensors are installed by many manufacturers. If the car does not have parking sensors, then it can be installed without any problems at any car service center. If you have the skills to repair a car, or are familiar with maintenance, then you can carry out the procedure for installing parking sensors yourself, having previously selected the type of parking system you need.

Improvements in the “Norma” package

The “Norma” option was supplemented with an optional package – heated mirrors and seats. A speed limiter, cruise control, and a set of necessary elements appeared:

PTF headlights;
12 Volt cartridge in the trunk;
The low beam can be turned off with a delay (40 seconds).

The 2DIN height radio remained in place. The BC received a gear shift prompt function. The upper display shows the temperature, and the lower display shows the “hint”.

How does the parking sensor work?

The parking sensor device is quite simple, and it can be divided into several components. These are an indication unit, a control unit and special sensors. There are models in which the control unit is single. In this case, the indicator unit can be either a buzzer or an LED or liquid crystal display.

So what is parking sensors, and what is its operating principle based on? The operation of an acoustic parking system is based on the properties of sound waves. Ultrasonic radar is able to correctly determine the distance from the car's bumper to the closest obstacle. The system transmits an impulse using a transmitting device; upon reaching an obstacle, it is reflected. The device receives the reflected signal, and with the help of a controller, based on the time it takes the beam to travel to the obstacle and back, calculates the distance to the obstacle.

Information about the distance between the vehicle and the obstacle is instantly displayed on the display. It is usually attached to the car's dashboard or rearview mirror. If desired, it can be mounted in any other place. The system is also equipped with speakers that warn the driver with sound. Typically, the parking sensors emit the first signals when the car approaches an object closer than 1-2 meters. If the obstacle is at a distance of 0.1-0.4 m, the signal does not stop until the reason for the system’s response is eliminated.

If you engage reverse gear and start moving backwards, the parking sensors also engage simultaneously with reverse gear. The system, with sensors mounted on the rear bumper, will receive power from the reversing light circuit.

If the car has corner or front parking sensors, the system is activated when the car is moving at low speed, namely up to 20 km/h.

Installing a parking radar is not difficult - usually a wire is laid along the car body, which connects the display unit with the sensors. In addition, there are wireless systems. This type of parking sensors is much more convenient to install than wired ones.

What types of parking sensors are there?

Ultrasonic parking systems are loved by most residents of the CIS and Russia. Although, many have not yet fully understood the concept of parking sensors and what it is in a car. And also what types they are. The operation of parking sensors can be based on the work of either ultrasonic or electromagnetic waves. Let's look at how such parking sensors work and what is their difference.

Ultrasonic parking sensors are usually installed on the bumper. This type of parking system determines the distance to the nearest obstacles using ultrasound reflected from these objects. This is similar to the principle of operation of an echo sounder. First, the system detects an approaching object, then a momentum is generated (most often ultrasonic). After this, the sensor perceives the reflected sound signal. The distance to the obstacle is calculated based on the time measured by the electronic unit and the speed of the reflected signal. Before displaying data on the display, several sensors are polled. As a result, the radar will notify you of approaching an object using signals.

The standard system includes two sensors that are mounted on the rear bumper. There are also parking sensors with 4 sensors. They are designed to monitor blind spots. In addition, there are complex parking sensors - with 6 or 8 sensors, which are installed on both bumpers. The parking systems market can offer very unusual solutions - there are parking sensors in which sensors need to be attached to the sides of the car. Today, it is ultrasonic radar that makes up the bulk of parking radars.

The second type of acoustic parking system is electromagnetic parking sensors. The main role in it is played by a special metal-coated tape. She is a sensor, i.e. the heart of the system. Usually it is glued inside the car, on the back of the bumper. The metallized tape is responsible for creating an electromagnetic field. When any object appears in the area of this field, it causes “irritation” and the system notifies the driver about the obstacle.

The most popular electromagnetic parking sensors are Audi's APS (brand DP1). This type of parking sensors is usually installed by most Americans and Europeans.

These are the basic principles on which the work of parking sensors is based, and in their diversity, today, they can be different. Parking sensors equipped with a rear view camera are one of the most convenient models. Thus, the driver not only receives audible warnings, but can also see what is happening behind the car. The camera gives a full overview and a good picture. At the same time, sound sensors give signals, telling the driver the distance to the obstacle.

Wireless parking sensor systems are easy to install; the absence of wires eliminates the work required to install them. This greatly simplifies the process of installing the device in a car.

Selection of parking sensors for Lada Granta

A special device with parking sensors will allow you to leave your car, even if there are obstacles in the form of other cars. In addition to the cars of other car owners mentioned above, examples of obstacles include low curbs, bumps, fences, enclosing flower beds, and so on. Most of these obstacles do not fall into the driver's field of vision, as a result of which he may not notice them and cause a collision. Parktronic will not allow the latter, warning the motorist about the interference with an audible signal. Parking sensors are also able to determine the distance to an obstacle.

The number of parking sensors on one device varies: there can be from 2 to 8. There are usually 4 sensors mounted on the rear bumper of a car.

What functions do parking sensors have?

Parking sensors for Lada Granta cars have a variety of capabilities, it all depends on the model of the parking device:

presence of radar and the ability to sound a signal. The device will warn the driver about approaching an object blocking the road, and the radar will be activated;
parking radar visual warning. In addition to the sound signal that the parking sensors for Lada Granta cars will emit, if there is a risk of hitting something, the driver will be able to see the outline of the obstacle, which will be displayed on the display.
CCTV camera located in the rear of the car. With such a video device, the problem with a limited field of view when moving backwards disappears by itself.

A useful device that has deservedly received a large number of positive reviews from users.

Parking radars (or parking sensors) are often purchased by novice car owners, which greatly simplifies their task of maneuvering in confined spaces. However, they are often included in the package of very expensive cars, and you should not take them as a sign of an incompetent driver - rather, they are a very useful accessory.

On cars with poorly calculated visibility in the rear hemisphere, parking sensors will be by no means useless.

What are the features of using parking sensors?

Having studied enough information about the parking system and looked at the parking sensors in the photo, you have made your choice and installed the miracle device in your car. It should be remembered that technology needs human care. And in order for its operation to be trouble-free and correct, it is necessary to take into account the nuances listed below and try to prevent them. Problems in the operation of parking sensors can be created by:

dirt, ice and snow stuck to the sensors;
if the car is moving on an uneven road or on an incline;
rough terrain can also cause misleading signals;
increased noise;
adverse weather conditions;
radio;
dents and holes in the asphalt;
not closed sewer hatches;
sharp or thin objects.

Be sure to take note of this and do not rely 100% on technology, because it cannot always ensure your safety.

The main prerogative of parking sensors is the ability to monitor areas that the driver cannot control from his seat, i.e. so-called “blind spots”. This will help avoid accidents and other difficulties for the driver on the road.

Autolikbez October 25, 2017

Not every driver is able to “feel” the dimensions of the vehicle and accurately drive close to various obstacles and other cars, which is quite important in urban conditions. An assistant in such a situation is a parking radar (parking sensors), which appeared in the design of imported cars back in the 90s of the last century. The task of the electronic device is to prevent a collision by giving a warning signal when approaching any object. What is parking sensors in a car and how it functions, read in this publication.

Sensor tuning

Before installing the sensors, they can be painted to match the color of the car. In case the radars do not fit correctly, several spacer rings should also be painted. Painted parking sensors look very cool. They are practically invisible on the car.

Important. Locators need to be painted over only after marking. After all, some of them may end up on the jumper, which is different in color from the main body.

How does parking radar work?

Parktronic is a complex electronic system consisting of several main elements:

control and signal processing unit;
ultrasonic sensors mounted in elements of the car body (usually the front and rear bumpers);
device for sound and visual warning of the driver.

Each sensor continuously sends an ultrasonic signal that is reflected by the surfaces of surrounding objects. If an obstacle is at close range, the device detects the reflection and transmits information to the control unit controller. The latter determines the distance to the obstacle by wavelength and response speed, after which it gives the appropriate command to the sound device and display.

How parking sensors of the simplest design work:

Two sensors are installed in the rear bumper of the car, distributing ultrasound in a coverage sector of approximately 45° in front of them.
When you back up and approach an obstacle within 2 m, the electronics beep the first sound.
As you approach the object, the signal sounds more frequently, and at a distance of 30 cm from the surface it becomes continuous.

In some car models, the unpleasant sound of the buzzer is replaced by a voice warning, telling you how many meters are left before the collision.

The budget version of the device has a visual indication through a simple display on which strips of different heights light up. The closer the surface of the object, the more stripes flash on the screen. When the distance is reduced to critical, the indication is reflected in red.

While driving along city streets, other road users often approach the car (especially in traffic jams). In order not to irritate the driver with a useless buzz, the parking sensors are activated after engaging reverse gear.

The operating principle of parking sensors, based on the reflection of ultrasonic signals, has long been used in road patrol radars. Based on the wavelength and response speed, the device calculates not only the distance to the object, but also the speed of movement.

Wireless devices

The modern market offers many devices. The most popular product is wireless parking sensors with a rear view camera. It is often purchased by novice drivers who do not yet know how to confidently move along the road in traffic.

Like wired devices, wireless systems are designed to make parking as easy as possible. The system will warn the driver in advance about an obstacle behind. Some models implement this warning differently. Some devices have a display for this purpose; on cheaper and more accessible models, the warning is implemented through a simple sound signal. In some models, the signal is sent by voice. So, speaking parking sensors in the purest Russian language, instead of a beeping signal, they will tell the driver how many meters to the obstacle, and will warn when to stop.

Among the advantages that wireless devices have are ease of installation, no problems with pulling wires, comfort during use, and the small space that the device takes up.

The system operates thanks to the control unit. It processes radio signals and can output to a screen. The signals from different devices are different, but do not be afraid - they do not interfere with each other.

The display is connected to the on-board network, and can be installed anywhere in the car interior. This inexpensive parking sensor is suitable for many brands of cars. These models can also be used on trucks.

Types of systems

The parking sensor design described above is considered outdated and primitive. Two sensors built into the rear bumper are able to “see” only solid obstacles located behind the car. Objects in the form of poles and street trash cans that are shifted away from the center of the car may not be detected by the devices. The reason is that the area behind the vehicle is too narrow. There is no front collision insurance at all.

Therefore, the following types of parking radars are installed on modern cars:

Budget version - 3 sensors in the rear bumper, one in the middle, two on the sides. Unfortunately, with such an arrangement, there are “blind” spots behind the car.
Full coverage of the space without “blind” spots is provided by 4 ultrasonic devices mounted in the rear body kit at intervals of 40 cm.
Two sensors in the front bumper and 4 in the rear. This system allows you to safely park in reverse and maintain a distance from large objects located in front.
The most expensive version - eight devices (4 pieces in each body kit) is relevant for novice drivers. Parking sensors fully control the space in front and behind the car.

Note. To prevent sound or voice signals from distracting the driver while driving, a group of tracking devices has been disabled, and in some modifications one specific parking sensor can be deactivated.

The screen with a scale does not give the driver a clear picture of what is happening behind and in front of the vehicle. It indicates approaching an obstacle and signals when the distance to the surface of the object becomes dangerous. The full picture can be seen on the liquid crystal display installed on the center console of many modern cars.

The display receives the image from at least two cameras combined with ultrasonic sensors. A marking grid is superimposed on the picture, using which the driver can easily determine the remaining distance to the object. Reversing is also accompanied by voice prompts (the function can be turned off if necessary). The parking sensors are designed in such a way that they are activated after switching to reverse gear; the system does not function while driving.

The latest modifications of electronic devices are equipped with several additional functions:

the screen shows not only a picture with a superimposed grid, but also the trajectory of the car;
instead of a display, the image is displayed directly on the windshield (the so-called projection), the driver does not need to look from the road to the screen;
display of various useful data - date, current time, mileage and outside temperature.

Installation of the control unit

The control unit is installed in the rear of the car, since it must be connected to the reverse signal and the vehicle's ground, as well as to the positive after the ignition switch. The equipment is connected to the reverse signal for the operation of the rear bumper sensors, and to the plus signal for the operation of the front radars.

The easiest way to connect is through the positive of the fuel pump. True, in this case the equipment will only work when the engine is running, but this is even better and more convenient.

Important. The wire from the reverse gear can be easily identified using an LED tester.

Recommendations for choosing and installing parking sensors

Manufacturers do not provide parking radars on budget models of passenger cars. This is not a problem for a car enthusiast who is concerned about safe driving: parking sensors can be purchased and installed yourself. It is necessary to purchase an installation kit, which includes sensors, a small remote display and an electronic control unit with wires.

Note. A screen in the center console is found on many cars that are not equipped with parking electronics. To connect the display to the controller, you will have to contact a dealer car service - doing this yourself is quite difficult. It's easier to install a remote indicator.

When choosing parking sensors with an ultrasonic operating principle, consider the following recommendations:

There are kits with overhead (glued) and mortise sensors. It is better to choose the second option, although a similar set is more expensive. Experience shows that cheap stick-on devices often fall off and come off.
Take a kit that includes at least 4 ultrasonic scanners installed in the rear body kit. If you want to monitor the front of your vehicle, buy a set of six sensors.
Always relevant advice: try not to buy cheap products made in the Republic of China.

Before installing parts, read the instructions and diagram included with the installation kit . Prepare a drill with a core drill, which can be used to make neat holes for each parking sensor. During the connection process, you may need a tester or multimeter to test the wires.

The most difficult moment is drilling holes and attaching ultrasonic elements. Ideally, you need to remove the bumper, mark the mounting points at intervals of 30–40 cm and make holes. Observe the direction of drilling from outside to inside so as to minimally cling to the paintwork. Then attach the sensors and install the body kit on the car.

The next steps are installing the indicator with the electronic unit and routing the wires. The placement of these elements is individual for each car brand, so the only recommendation is to fix the display in a convenient place so that it does not interfere with your view, and hide the controller under the dashboard. Place the wiring under the floor covering.

In this article we will talk about what parking sensors are in a car, how they work and how to install them yourself. In short, parking sensors or parking radar (in English literature Parking sensor) is a sensor system with an electronic warning system that helps the driver maneuver in confined spaces. If there is a risk of collision, the parking sensors warn the driver about this with an audible signal, and also display the distance to the obstacle on the display.

How does parking sensor work?

The operating principle of the parking radar.

Parking radar sensors are its “working” sensitive elements, which are installed on the rear and front bumper. Sensors detect obstacles at distances from 2 m to 0.2 m, which the driver is notified about through signals and display.

Parking radar sensors operate using ultrasonic signals that are reflected from surfaces around the car (the body of another car, a tree stump, a pole, etc.). Sensors record these reflected waves and transmit information to the electronic parking sensor unit. In the block, the information is processed (the distance to the obstacle is calculated based on the wavelength), and then displayed on a scale in the form of bars, or on a display in the form of numbers. At the same time, a sound signal is given using the built-in beeper. The closer the distance to the obstacle, the more often the sound signal sounds. If the distance is less than 30 cm, then it becomes continuous.

If an obstacle is in the zone of a possible collision, the driver hears a signal and can see on the parking sensor display the distance to the obstacle in meters or centimeters. However, if the number of sensors is insufficient, the parking sensor may “not notice” objects that are thin or that fall into the “dead zone”.

Connecting sensors

Before starting work, the installation site is taped with masking tape. Markings are made on it and installation points are indicated. All sensors should be located at the same height and equal distance from each other at an angle of 90 degrees to the ground.

After marking, you can start drilling holes. This is done using a screwdriver or drill with a cutter pre-attached to them, which comes with the parking sensors. After sharpening the grooves, the tape is removed from the bumper, and the holes are cleaned with a sharp knife or file.

Important. It is not necessary to remove the car bumper to install and connect parking sensors. In most cases you can do without this.

It is convenient to install sensors in the holes using a hook, which can be made from thick wire. The wires are pulled in strict order in the direction from the one farthest from the radar unit to the closest. Use a hook to hook the wires through the holes and pull them through. First, one wire is pulled, then two, 3 wires are pulled into the third hole, and 4 into the fourth. After pulling, the cables are straightened, tied into a bundle with electrical tape and passed through a plug into the inside of the car. Where possible, they are fastened with nylon ties and only then connected to the main unit.

To fix the sensors themselves in the holes, lightly press them and snap them inward. In this case, you do not need to press hard on the center of the radar. The pressure should be as smooth and accurate as possible.

Which parking sensor is better to choose?

Four sensors in the rear bumper of a car

When choosing parking sensors, you first need to focus on the number of sensors. Models currently available for:

Two or three sensors. Parking radars with 2 or 3 sensors are generally considered to be outdated and uninformative. To cover all possible blind spots, there must be at least four parking sensors in the rear.
Four sensors. All of them are installed on the rear bumper. And this amount is sufficient to “see” everything that is happening behind the car. Parking sensors with 4 sensors are very popular due to their low price, but do not provide information about obstacles ahead.
Six sensors. Most drivers consider parking sensors consisting of six sensors (the so-called “all-round” parking sensors) to be optimal in terms of the combination of price and information content. Four are installed on the rear bumper, approximately 40 cm apart. Two more are mounted in the front bumper. This installation scheme for parking sensors has good information content and reliability. Modern models have the option of turning off sensors in the front or rear. If desired, the driver activates sensors only on the front or rear of the vehicle.
Eight sensors . These are expensive models of parking sensors. But many novice drivers choose them, since parking radars with eight sensors detect any obstacles. The use of parking sensors with a large number of sensors has some peculiarities. Often, when driving, an overly sensitive radar distracts the driver. Therefore, devices with eight or ten sensors turn on for approximately 20 seconds at the beginning of movement. Then they are activated only when braking. Some models can be turned off by the driver using a button.

Additional installations and features of interior equipment Grants “Standard”

The initial equipment of the Granta Standard cabin is quite modest, but this in turn is a kind of advantage. The buyer, if desired, will be able to ideally re-equip the vehicle for personal use and supplement it with everything necessary.

When purchasing from a car dealer, you can find out the cost of all installations and their availability. And since the price of the car itself is quite small, with a minimal investment you can buy everything you need and even re-equip it yourself. The most popular modifications among new owners of the standard equipment are the following:

1. Passenger handrails.

2. Central locking.

3. Airbags.

4. Anti-theft alarm.

5. Lamp lamps for the rear row and trunk.

6. Rear seat headrests.

The car is initially equipped with ISOFIX child seat mounts and special latches for locking the rear locks. Additionally, the standard Lada Granta equipment to provide increased protection includes an immobilizer that allows you to lock the vehicle systems. The vehicle is equipped with daytime running lights.

The rear seats have a common design without a 40:60 split, and a special automotive fabric with increased strength and wear resistance is used as a cover for the seats. Like all other models in this series, there is a sun visor for the driver.

The model is equipped with 13-inch wheels; in addition, the owner receives a spare 13-inch full-size wheel. The model's bumpers are painted in body color, which allows you to give the car a perfect look.

The buyer is offered the Grant Standard equipment in a color scheme consisting of classic colors (white, black, silver). Metallic tones for this modification must be ordered separately.

It is also possible to further re-equip the exterior with new bumpers and a radiator grille, since the standard assembly features simplified but durable body elements.
