The system draws the driver's attention to
hazardous situations:
- Vehicles with adaptive cruise control: A d is·
ta nce warning is given if you are too close to
the vehicle in front for more than just a mo·
ment. If the vehicle in front were to brake
hard, a collision would no longer be avoida·
ble. This is indicate d by a warning lamp • .
- A collisio n warning is given if the vehicle in
front is much slower than you or if it brakes
hard. If this warning is given, you may need
to take evasive action or brake hard to avoid
a collision. The driver message Aud i pre

If you do not t ake appropriate action in time,
the pre sense front will assist by applying the

WARNING
-
- The protection provided by pre sense
front is still subject to the prevailing
physical limits. It is a driver assist func·
tion and cannot prevent a collision on its
own. The driver must always intervene
personally. As the driver you are always
responsible for braking in good time. Do
not let the extra safety provided tempt
you into taking any risks when driving -
this can cause accidents.
- Due to inherent system limitations, false
activation of the system is possible.
- Please note that the sensor is not always
able to detect all objects which may rep-
resent a potential hazard (accident risk).
- Pre sense front does not react to people,
animals, crossing traffic or objects that
cannot be clearly recognised

116, General notes.
- Reflecting objects, such as crash barriers,
the entrance to a tunnel, heavy rain or
ice can impair the function of the radar
sensor a nd the ability of the system to
detect a collision risk.

CAUTION
Impacts or damage to the bumper, wheel
arches or underbody can cause misalign-
ment of the sensor. This can impair the
function of the pre sense front system .
Have the systems checked by a qualified
workshop.
