Option/accessory, for more information, see Introduction.
Activating/deactivating warning signals
The warning lamp is activated automatically
when the engine is started if the system is
switched on.
The warning sound can be activated/deacti-
vated separately using the options for
On or
Off in the menu system MY CAR under
Settings Car settings Driving support
systems Warning sound if risk of
collision .
Set warning distance
The warning distance regulates the distance at
which the visual and acoustic warnings are
deployed. Select one of the options from
Long
,
Normal
or
Short
in the menu system
MY CAR under Settings Car settings
Driving support systems Collision
Warning Warning distance .
The warning distance determines the system's
sensitivity. Warning distance
Long
provides an
earlier warning. First test with Long and if this
setting produces too many warnings, which
could be perceived as irritating in certain sit-
uations, 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 colli-
sion 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 the Distance
Alert set at time interval 4 – 5. see
page 183.
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.
Checking settings
The settings required can be controlled on the
centre console display screen. Search with the
menu system
MY CAR under Settings Car
settings Driving support systems
Collision Warning , see page 144.
Limitations
The collision warning system is active from and
including approx. 4 km/h.
The visual warning signal may be difficult to
notice in the event of strong sunlight, reflec-
tions, when sunglasses are being worn or if the
driver is not looking straight ahead. The warn-
ing sound should therefore always be acti-
vated.
On slippery road surfaces the braking distance
is extended, which may reduce the capacity to
avoid a collision. In such situations the ABS
and DSTC systems will provide best possible
braking force with maintained stability.
NOTE
The visual warning signal can be temporarily
disengaged in the event of high passenger
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 movements
are large, e.g. a very active driving style.
