Introduction
Front Assist has physical and system-related limitations. From the driver's perspective, some Front
Assist reactions may therefore occur unexpectedly or with a delay in certain circumstances. You
should therefore always be prepared to take full control of the vehicle if necessary.
• In tight bends.
• If the accelerator is fully depressed.
• If Front Assist is switched off or faulty.
• If TCS is switched off manually.
• If ESC is taking corrective action.
• If there is a fault in several brake lights on the vehicle or on a trailer with an electrical
connection to the vehicle

.
• If the radar sensor is dirty or covered.
• If there are metal objects, e.g. tracks in the road or metal plates used in roadworks, or road
signs, above and adjacent to the road.
• If the vehicle is reversing.
• Under hard acceleration.
• In snow or heavy rain.
• In case of narrow vehicles, e.g. motorbikes.
• If vehicles are travelling slightly to the left or right of your vehicle.
• If vehicles are crossing in front of your vehicle.
• If there is oncoming traffic.
• If pedestrians are standing in front of the vehicle, approaching the vehicle, or moving in the
same direction as the vehicle.
• In complex driving situations, e.g. at traffic islands.
• In unclear traffic situations, e.g. vehicles ahead are heavily braking or turning off.
• When loads or attachment parts on other vehicles protrude to the side, rear or above the normal
dimensions of the vehicle.
Switching off Front Assist
• If the vehicle is being towed.
• If the vehicle is on a rolling road test bed.
• If the vehicle is driven in areas other than public roads.
• If the radar sensor is faulty.
• After external force on the radar sensor, e.g. after a rear-end collision.
• In the event of multiple unwanted interventions.
• If the radar sensor is covered temporarily by any auxiliary equipment, e.g. auxiliary headlights.
• If the vehicle is loaded onto a truck, car ferry or motorail train.
The intelligent Pedestrian Monitoring technology cannot overcome the laws of physics,
and functions only within the limits of the system. Never let the extra convenience
afforded by the Pedestrian Monitoring system tempt you into taking any risks when
driving. The driver is always responsible for braking in time.
• If Pedestrian Monitoring issues a warning, brake your vehicle immediately depending
on the traffic situation or avoid the pedestrian.
• The Pedestrian Monitoring system cannot prevent accidents and serious injuries on its
own.
• The Pedestrian Monitoring system can issue unnecessary warnings and carry out
unwanted braking interventions in complex driving situations, e.g. on a twisting main
road.
• The Pedestrian Monitoring system can issue unnecessary warnings and carry out
unwanted braking interventions when its function is impaired, e.g. if the radar sensor is
covered or its position has been changed.
• Be prepared to take over control of the vehicle yourself at all times.
WARNING
Failure to switch off Front Assist in the situations mentioned can result in accidents and
serious injuries.
