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 cannot react – or will react with a delay – in the case of the following objects:
—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.
—Stationary or oncoming pedestrians; generally no reaction to persons without Pedestrian Monitoring.
—Stationary or oncoming cyclists; additionally no reaction to crossing cyclists without Cyclist Monitoring.
—When pedestrians and cyclists are not detected, for example because they are partially or fully hidden.
Function limitations
Front Assist may not react or may react with a delay or with an unwanted response in the following situations:
—In tight bends.
—Driving in heavy rain, snow or heavy spray.
—Driving in multi-storey car parks and tunnels.
—Driving on roads with embedded metal objects, e.g. railway tracks.
—Reversing.
—If TCS
is switched off manually.
—If ESC
is performing a control intervention.
—If the radar sensor is dirty, covered or damaged.
—If several brake lights on the vehicle are defective.
—If there is a fault in several brake lights on a trailer or bicycle carrier with an electrical connection to the vehicle.
—If the vehicle accelerates hard or the accelerator is fully depressed.
—In complex driving situations, e.g. at traffic islands.
—In unclear traffic situations, e.g. vehicles ahead are braking heavily or turning off.
—If there is a fault in Front Assist.
Switching off Front Assist
Front Assist is not suitable for use in the following situations due to the limitations of the system and must be
switched off → Switching off Front Assist:
—If the vehicle is utilised in a capacity beyond usage on public roads, e.g. offroad or racing tracks.
—If the vehicle is being towed or is loaded onto another vehicle.
—If the radar sensor is covered by any auxiliary equipment, e.g. auxiliary headlights.
—If the radar sensor is faulty.
—If components in the area of the radar sensor are exposed to external force, e.g. after a rear-end collision.
—In the event of multiple unwanted interventions.
