Warning messages
Overtake request when adaptive cruise
control is active (ACC active)
If adaptive cruise control detects that braking
assistance is required on the part of the driver, a
warning signal sounds and the warning message
“
Distance Please brake
” appears on the multi-
function display.
In this case, the braking power of the adaptive
cruise control is not sufficient to prevent a
collision.
f
Brake immediately.
Traffic situations in which vehicles cannot
be reliably detected
The radar sensor for adaptive cruise control scans
a narrow, cone-shaped area in front of your
vehicle.
Detection can be limited or unreliable, depending
on the traffic situation and the size of the vehicle
in front. The system may brake too late or
unexpectedly.
Stationary vehicles are not detected. The system
cannot respond to stationary vehicles.
f
Drive with extreme care.
f
Slow down if necessary.
A – Vehicles changing lanes/cutting in
If a vehicle is changing lanes or cutting in ahead of
you in the same lane, the vehicle will only be
detected when it has moved completely into your
lane.
B – Vehicles with a small cross-section/
narrow vehicles
Narrow or small vehicles will not be detected or
will be detected too late.
