Speed of the vehicle.
The work area can therefore be limited if the vehicle approaches an object very quickly and thus has little time to react.
Furthermore, not all warning levels are passed through in all situations. Depending on the speed, there may not be, for
example, an advance warning or immediate warning, but rather an automatic braking maneuver that occurs straight away, so
as to best protect the detected object.
Distance warning
Front Assist detects if there is a safety hazard from following the vehicle ahead too closely.
The indicator light turns on. Increase the distance.
Advance warning
Front Assist detects a possible collision and prepares the vehicle for possible emergency braking.
A warning tone sounds and the warning light turns on. Apply the brakes or maneuver to avoid the collision.
Immediate warning
If you do not respond to the advance warning, the brakes may be applied briefly to indicate the increasing risk of a collision.
Apply the brakes or maneuver to avoid the collision.
Automatic braking
Autonomous Emergency Braking (Front Assist) can brake the vehicle automatically in several stages of increasing braking
force. Reducing the vehicle speed may help to reduce the damage resulting from a collision.
Braking support
If the system detects that you are not braking enough before an impending collision, Front Assist can increase the braking
force and thus help to reduce the risk of a collision. The braking support is only active as long as you are firmly pressing the
brake pedal.
Front Assist system limitations
Please read the introductory information and heed the Warnings and Notice ⇒
Introduction.
Limits of the sensor system
Front Assist detects driving situations using a radar sensor in the front of the vehicle. The radar sensor has a range of up to
approx. 120 m (approx. 400 ft).
Observe the limits of the radar sensor ⇒ Limits of the sensor system . Always be attentive and intervene yourself if
necessary!
After starting the vehicle
Autonomous Emergency Braking is not available or availability is limited directly after starting the vehicle or after
restarting the system. During this time, the white indicator light in the instrument cluster display comes on.
Unrecognizable objects
Autonomous Emergency Braking (Front Assist) may not react or may react with a delay to the following objects:
If there are oncoming vehicles or vehicles crossing the street
Stationary or oncoming pedestrians; generally no reaction to people without Pedestrian Monitoring.
Stationary cyclists, oncoming cyclists or cyclists crossing the street.
Pedestrians and cyclists who are not detected as such, for example because they are fully or partially hidden.
