Driver assistance systems
Sensor system information
Introduction
Depending on the vehicle equipment,
the vehicle has driver assistance
systems that increase driving
convenience. These driver assistance
systems use some sensors and cameras
(hereafter referred to as the “sensor
system”) that are 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 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.
If 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:
136
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.
If the camera is not available due to long exposure to direct sunlight or high ambient temperatures.
If the camera field of view is covered, dirty or damaged.
If 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
Fig. 86 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. 87 Narrow vehicle.
Vehicles that are driving close to your vehicle but outside the sensor range, such as motorcycles, cannot be detected.
Fig. 88 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:

Autonomous Emergency Braking (Front Assist) ⇒ System Limitations of Front Assist.

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.
The following indicator lights may turn on depending on the driving situation and the instrument cluster version:
Cruise control system is switched on, speed regulation active.
If the cruise control system is not regulating the speed, the indicator lights are small or grey.
If no speed is stored, the instrument cluster display shows
instead of the speed.
Driving downhill
The vehicle cannot maintain the saved speed in all driving situations. Always be ready to apply the brakes.
1. Use the electric drivetrain recuperation when traveling downhill for extended periods.
This relieves the strain on the brakes.
WARNING
If it is not possible to drive safely with enough distance and a constant speed, using the cruise control system may cause accidents and serious or fatal injuries.
Always adapt your speed and distance to vehicles driving ahead based on the visual, weather, road, and traffic conditions. The driver is always
responsible for the speed.
Never use the cruise control system when visibility is poor, when there is not enough distance, or when roads are steep, winding, flooded, or slippery, for
example from snow, ice, moisture, or gravel.
Never use the cruise control system when driving off-road or on unpaved roads.
Operating the cruise control system
