WARNING
-
-
Pre sense cannot overcome natural physical
laws .
It
is a system designed to assist and it
cannot prevent a collision. Do not let the in-
creased safety provided tempt you into tak ing
risks. This could increase your risk of a colli-
sion.
- The system can dep loy incorrectly.
- Please note that t he sensors do not always
detect all objects. This increases the risk of
a collision.
- Pre sense does not react to peop le or ani-
mals or objects that are crossing the vehi-
cle's path or are difficult to detect
¢page 95.
- Reflective objects such as gua rd rails or the
entrance to a tunnel, heavy rain and ice can
affect the funct ion of the radar sensors and
the system's ab ility to detect a collision risk.

Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housi ng and
underbody. Pre sense can be impaired by this .
