NOTE
Even if the warning distance has been set
to
Long warnings could be perceived as
being late in certain situations, e.g. when
there are large differences in speed or if
vehicles in front brake heavily.
WARNING
No automatic system can guarantee
100 % correct function in all situations.
Therefore, never test Collision Warning
with Auto Brake by driving at people or
vehicles - this may cause severe damage
and injury and risk lives.
Checking settings
The current settings can be controlled via the
centre console's screen and the menu sys-
tem (p. 114) MY CAR.
Maintenance
Camera and radar sensor

.
For the sensors to work correctly, they must
be kept clear of dirt, ice and snow, and be
cleaned regularly with water and car sham-
poo.
NOTE
Dirt, ice and snow covering the sensors
will reduce their function and may prevent
measurement.

Collision warning system* - limitations
The function has certain limitations - for
example, it is not active until approx. 4 km/h.
The collision warning system's visual warning
signal (see (1) in the illustration (p. 230)) may
be difficult to notice in the event of strong
sunlight, reflections, when sunglasses are
being worn or if the driver is not looking
straight ahead. The warning sound should
therefore always be activated.
On slippery road surfaces the braking dis-
tance is extended, which may reduce the
capacity to avoid a collision. In such situa-
tions the ABS and ESC (p. 191) systems will
provide best possible braking force with
maintained stability.
NOTE
The visual warning signal can be temporar-
ily disengaged in the event of high passen-
ger compartment temperature caused by
strong sunlight for example. If this occurs
then the warning sound is activated even if
it is deactivated in the menu system.
•
Warnings may not appear if the dis-
tance to the vehicle in front is small or
if steering wheel and pedal move-
ments are large, e.g. a very active driv-
ing style.
