Warning function
Light in the exterior mirror
Advance warning
The dimmed light in the exterior mirror indicates
when vehicles are in the blind spot or are ap‐
proaching from the rear.
Acute warning
If the turn indicator is switched on while a vehicle
is in the critical area, the steering wheel vibrates
briefly and the light in the exterior mirror flashes
brightly.
The warning is terminated when the other vehi‐
cle has left the critical area or the turn signal is
deactivated.
Vehicles with side collision warning
If there is no response to the steering wheel vi‐
brating and a lane marking is crossed at speeds
of up to 210 km/h, 130 mph, the system inter‐
venes if necessary with a brief active steering in‐
tervention. The steering intervention helps to re‐
turn the vehicle to its lane. Steering intervention
can be felt at the steering wheel, and can be
overridden manually at any time.
Flashing the light
When the vehicle is unlocked, the system per‐
forms a self-test by flashing the light.
System limits
Safety note
WARNING
The system may not respond at all, or may re‐
spond too late, incorrectly or without justifica‐
tion due to system limitations. There is a dan‐
ger of accidents or damage to property.
Observe the information on the system limits
and intervene actively if necessary.
Upper speed limit
The system is temporarily disabled at speeds
over approx. 250 km/h, 155 mph.
At speeds below approx. 250 km/h, 155 mph,
the system once again responds according to
the setting.
Functional limitations
The system may have limited functionality in the
following situations, for example:
▷ If the speed of the approaching vehicle is sig‐
nificantly higher than the driver's own speed.
▷ In thick fog, wet conditions or snow.
▷ On sharp bends or narrow roads.
▷ If the bumper is dirty, iced up or covered,
for example by stickers.
▷ After work performed incorrectly on the vehi‐
cle paintwork.
▷ When a projecting load is being transported.
Attaching any objects, for example stickers or
decals, in the area of the radar beam will also im‐
pair radar sensor operation and may even cause
them to fail.
In vehicles with side collision warning, the steer‐
ing intervention may be limited in the following
situations, for example:
▷ When there are missing, worn, poorly visible,
merging/separating or ambiguous lane mark‐
