Get Driver assist systems -> Sensors and cameras Guide for Volkswagen Touran 4 Door Third Generation (2022-2025)

Introduction

Depending on the vehicle equipment, the vehicle has driver assistance systems that increase driving convenience.

Some of these driver assistance systems use sensors or cameras (hereafter referred to as the “sensor system”) that

are not or only partially visible to you.

The sensors and cameras visually detect the vehicle's surroundings ultrasonically or by using radar waves.

Installed sensor systems

Depending on the vehicle equipment, the following sensor systems may be installed:

—Radar sensor in the front of the vehicle.

—Radar sensors in the rear of the vehicle.

—Camera behind the windshield.

—Ultrasonic sensors in the front of the vehicle.

—Ultrasonic sensors in the rear of the vehicle.

You can find information on the relevant installation location in the vehicle overviews

WARNING

The driver assistance systems are not a replacement for the driver's attention and work only within their system

limitations. The driver assistance systems cannot detect all driving situations and may not provide warnings or react,

or may provide warnings or react with a delay, or may provide warnings or react in a way that is not desired. If you

are careless, there is a risk of accidents, serious injuries and death.

● Always stay attentive and do not rely solely on the system. The driver is always responsible for control of the

vehicle.

● Be aware of the limits of the sensor system and the system limitations of the individual systems.

● Always adapt your speed and distance to vehicles driving ahead based on the visual, weather, road, and traffic

conditions.

● Be prepared to override or interrupt automatic interventions at all times.

● Pay attention to indicators in the instrument cluster display and respond to the displays accordingly when the

traffic situation allows.

● Do not use driver assistance systems if you suspect a problem or damage.

Limits of the sensor system

Limits of the radar sensor

Driver assistance systems that use radar sensors may not respond, may offer a delayed response or may respond in

an unexpected way in the following situations:

—When driving in poor weather conditions, such as heavy rain, snow or heavy spray.

—When driving through construction zones, tunnels or toll stations.

—When driving on winding roads, for example, mountain roads

—In front of bumps or dips in the road

—When driving off-road

—When driving in parking ramps

—When driving on roads with embedded metal objects, such as railroad tracks

—When driving on gravel roads

—In complex driving situations, such as traffic islands.

—Following a violent impact affecting components within the range of the radar sensors, e.g. following a rear-end

collision.

—The radar sensors are obscured, dirty, misaligned or damaged.

Limits of the camera behind the windshield

Driver assistance systems that use the camera behind the windshield may not respond, may offer a delayed response

or may respond in an unexpected way in the following situations:

—In front of bumps or dips in the road

—When driving in construction zones

—When driving off-road

—When driving in poor weather conditions, such as heavy rain, snow, fog or heavy spray and poor road conditions.

—In low-lying sun, darkness or if there is glare from oncoming vehicles.

—The camera is not available due to long exposure to direct sunlight or high ambient temperatures.

—The camera field of view is obscured, dirty or damaged.

—The camera is misaligned.

Delayed reaction

If the sensor system is exposed to environmental conditions that limit its function, the driver assistance systems may

only be able to detect this with a delay. Therefore, the display that indicates that functions are impaired may be

delayed when you first start driving or while driving.

Limits in certain driving situations

261

Fig. 1 Driving around curves.

The sensor system always measures straight ahead. Therefore, on tight curves, vehicles may be detected by mistake

or vehicles driving ahead may not be detected.

Fig. 2 Narrow vehicle.

Vehicles that are driving close to your vehicle but outside the sensor range, such as motorcycles, cannot be detected.

Fig. 3 Changing lanes.

Vehicles that change to your lane close in front of your vehicle cannot be detected. This also applies to vehicles with

attachments exceeding the vehicle dimensions.

Specific system limitations

In addition to the limits of the sensor system, every driver assistance system has additional system limitations linked

to their function. Please also note these:

—Adaptive Cruise Control(ACC) (→ Adaptive Cruise Control (ACC)).

—Predictive cruise control (→ Predictive cruise control).

—Autonomous Emergency Braking (Front Assist) (→ Autonomous Emergency Braking (Front Assist)).

—Lane Assist (→ Lane Keeping System (Lane Assist)).

—Comfort drive Travel Assist (→ Comfort drive Travel Assist).

—Emergency Assist (→ Emergency Assist).

—Lane Change System (Side Assist) (→ Lane Change System (Side Assist)).

—Advanced Road Sign Display (→ Advanced Road Sign Display).

Troubleshooting

No forward sensor range or limited forward sensor range

Parts of the sensor systems in the front of the vehicle have limited availability or are not available. The yellow symbol

and a message are displayed for a few seconds.

—The sensor areas are dirty or the sensor system's view is limited due to weather conditions, such as snow, or from

detergent residue or coatings. Clean the sensor areas in the front of the vehicle and clean the windshield

(→ Vehicle care).

—The sensor areas are impaired by attachments, decorative frames on license plate holders, or labels. Keep the areas
