Get Driver assistance systems Guide for Volkswagen Jetta 4 Door Seventh Generation (2019-2025)

Driver assistance systems

Sensor system information

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 ⇒ 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

Please read the introductory information and heed the Warnings and Notice ⇒

Introduction.

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

211

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 ﬁrs

start driving or while driving.

Limits in certain driving situations

Fig. 108 Driving around curves.

212

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. 109 Narrow vehicle.

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

Fig. 110 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) ⇒ ACC system limitations.

Autonomous Emergency Braking (Front Assist) ⇒ Front Assist system limitations.

Lane Assist ⇒ Lane Assist system limitations .

Comfort drive Travel Assist ⇒

Introduction.

Emergency Assist ⇒ Introduction.

“Blind spot” sensor ⇒ System limitations of the “Blind Spot” Monitor.

Troubleshooting

Please read the introductory information and heed the Warnings and Notice ⇒

Introduction.

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

213

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

around the sensor system clear ⇒ Sensors and Cameras.

The sensor system is misaligned or damaged, for example as a result of damage to the front of the vehicle or the

windshield. Check if there is noticeable damage ⇒ Sensors and Cameras.

Painting work was carried out on or structural modiﬁcations were made to the front of the vehicle or the windshield

⇒ Repairs and technical modiﬁcations.

Malfunction or fault. Stop the engine and restart.

If the problem persists, contact an authorized Volkswagen dealer or authorized Volkswagen Service Facility. Volkswagen

recommends contacting an authorized Volkswagen dealer or authorized Volkswagen Service Facility.

If the sensor range is restricted, driver assistance systems may not be available or only to a limited extent. Refer to the

other indicator lights of the driver assistance systems ⇒ Symbols in the instrument cluster .

Additional information may be displayed in the vehicle status, depending on the malfunction ⇒ Vehicle settings menu.

Cruise control system

Introduction

The cruise control system helps to

maintain a set speed.

Speed range

The cruise control system is available at speeds above approximately 20 km/h (approximately 15 mph) when driving forward.

Driving with the Cruise Control System

You can override the stored speed at any time, for example, to pass another vehicle. The regulation function is paused while

the vehicle accelerates and then resumes the stored speed.

Displays

If the cruise control system is switched on, the instrument cluster display indicates the saved speed and the status of the

cruise control system.

One of the following indicator lights will light up, depending on the driving situation:

Cruise control system is switched on, speed regulation active.

Cruise control system is switched on, speed regulation

inactive.

If no speed is stored, the instrument cluster display shows

instead of the speed.

Changing gear

Pressing the clutch pedal pauses the regulation function. It resumes automatically after changing gear.

Driving downhill

The vehicle cannot maintain the saved speed in all driving situations. Always be ready to apply the brakes.

1. Downshift before traveling downhill for extended periods.

This will enable you to utilize the engine braking effect and reduce the load on the brakes.
