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.
Light and acoustic signals
To deactivate the light and acoustic signals:
•
Locate
Settings Car settings
Driver support systems Collision
Warning
- there select to uncheck the
box.
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.
Audible signal
The warning sound can be activated/deacti-
vated separately:
•
Select
On or Off in the menu system
under
Settings Car settings Driver
support systems
Collision Warning
Warning sound.
Set warning distance
The warning distance regulates the distance
at which the visual and acoustic warnings are
deployed.
•
Select
Long, Normal or Short in the
menu system MY CAR under
Settings
Car settings Driver support
systems
Collision Warning
Warning distance
The warning distance determines the sys-
tem's sensitivity. Warning distance
Long pro-
vides an earlier warning. First test with Long
and if this setting produces too many warn-
ings, which could be perceived as irritating in
certain situations, then change to warning
distance
Normal.
Only use warning distance
Short in excep-
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.
