Collision warning system* - operation

"Collision Warning with Auto Brake and
Cyclist and Pedestrian Detection" is an aid to
assist the driver when there is a risk of collid-
ing with a pedestrian, bicycle or vehicle in
front that are stationary or moving in the same
direction.
Settings for the collision warning system are
made from MY CAR via the centre console's
screen and menu system.
Warning signals On and Off
It is possible to select whether the collision
warning system's acoustic and visual warning
signals should be switched on or off.
When starting the engine, the setting that was
selected when the engine was switched off is
obtained automatically.
NOTE
The Brake Support and Auto Brake func-
tions are always activated - they cannot be
deactivated.

The warning lamp, see Collision warning sys-
tem - function (p. 224), is tested every time
the engine is started by briefly illuminating the
warning lamp's separate points of light if the
collision warning system's light and acoustic
warnings are activated.

Only use warning distance
tional cases, e.g. for dynamic driving.
NOTE
When the adaptive cruise control is in use
the warning lamp and warning sound will
be used by the cruise control even if the
collision warning system is switched off.
The collision warning system warns the
driver in the event of a risk of a collision,
but the function cannot shorten driver
reaction time.
In order for the collision warning system to
be effective, always drive with Distance
Alert (p. 214) set at time interval 4–5.
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.
