Urgent warning
If the driver fails to respond to the advance warning, the system may jolt the brakes briefly to make the driver aware
of the increasing risk of a collision. Brake or take evasive action!
Automatic braking
If the driver fails to respond to the urgent warning, the vehicle may be braked automatically by applying increasing
levels of brake force over several stages. The reduced speed may help to minimise the severity of an accident.
Braking intervention
If the system detects that the driver is braking insufficiently when there is a risk of collision, the system can increase
the brake pressure, hence helping to prevent a collision. The braking intervention works only for as long as the brake
pedal is depressed with force.
Distance warning
The system detects safety risks caused by driving too close to the vehicle in front. The indicator lamp lights up.
Increase the distance.
Speed range: approx. 65 km/h (40 mph) to 250 km/h (155 mph).
Front Assist limits
Front Assist is not available or its functions are restricted immediately after the vehicle is started. During this
time, the indicator lamp lights up in the display of the instrument cluster.
Front Assist has physical and system-related limitations. You should therefore always be prepared to take full control
of the vehicle if necessary.
Delayed response
If the camera or radar sensor is exposed to environmental conditions that impair functioning, the system may detect
this only after a certain delay. For this reason, any restrictions to functions may be displayed only after a delay at the
start of the journey and when driving (→ Autonomous Emergency Braking (Front Assist)).
Objects that cannot be detected
Front Assist may not react or may react with a delay or with an unwanted response in the following situations:
—Vehicles that are driving outside the sensor range in close proximity to your vehicle, e.g. vehicles that are driving
offset to your vehicle or motorbikes.
—Vehicles that change into your lane directly in front of your vehicle.
—Vehicles with bodies or attachments that project beyond the vehicle.
—Oncoming vehicles or vehicles crossing your path.
—Pedestrians and cyclists who are stationary or moving towards the vehicle.
—When pedestrians are not identified as such, e.g. because they are partially or fully hidden.
—Objects or narrow objects such as walls, rails, fences, posts, trees or garage doors.
