Driving and operating169Conditions for re-activation
The Active emergency brake system
can only be re-activated if:
● the gear lever is not in neutral
● parking brake is not activated
● vehicle is not cornering
System limitations In some cases, the active emergencybraking system may provide an
automatic braking in situations that
seem to be unnecessary, for instance
in parking garages, due to traffic signs
in a curve or due to vehicles in
another lane. This is normal
operation, the vehicle does not need
service. Firmly apply the accelerator
pedal to override the automatic
braking if the situation and the
surroundings permit.
In the following cases, active
emergency braking performance is
limited:
● driving on winding or hilly roads
● detecting all vehicles, especially vehicles with a trailer, tractors,
muddy vehicles, etc.● detecting a vehicle when weather
limits visibility, such as in fog,
rain, or snow
● driving during nighttime
● sensor in the windscreen or radar
unit behind the front bumper
blocked by snow, ice, slush, mud, dirt, etc.
● windscreen damaged or affected
by foreign objects, e.g. stickers
Complete attention is always required
while driving, and you should be
ready to take action and apply the
brakes and / or steer the vehicle to
avoid crashes.

camera obscured by dirt, mud, snow
etc.). In this case,park the vehicle and switch off the engine. Clean the
windscreen area around the camera
and the detection zone of the radar in the front bumper. When the warning
lights and messages still appear after
