RCrossing vehicles: DISTRONIC PLUS may mis-
takenly detect vehicles that are crossingyour

lights with crossingt raffic,for example, could
cause your vehicle to pull away unintention-

In such situations, brake if necessary.

Blind Spot Assist
General notes
Blind Spot Assist monitor sthe areas on either
side of the vehicle that are not visible to the
driver with two lateral, rear-facingr adar sen-
sors. Awarning lamp lights up in the exterior
mirrors and draws your attention to vehicles
detected in the monitored area. If you then
switch on the corresponding turn signal to
change lane, you will also receive an optical and
audiblew arning.
Blind Spot Assist supports you from aspeed of
approximately 20 mph (30 km/h).
Important safety notes
GWARNING
Blind Spot Assist does not react to:
Rvehicles overtaken too closely on the side,
placing them in the blind spot area
Rvehicles which approach with alarge speed
differential and overtak eyour vehicle
As aresult, Blind Spot Assist may not give
warnings in such situations. There is arisk of
an accident.
Always observe the traffic conditions care-
fully, and maintain asafe lateral distance.
Blind Spot Assist is only an aid. It may fail to
detect some vehicles and is no substitute for
attentive driving. Always ensure that there is
sufficient distance to the side for other road
users and obstacles.

Radar sensors
The radar sensors for Blind Spot Assist are inte-
grated into the rear bumper. Make sure that the
bumpers are free from dirt, ice or slush. The
sensors must not be covered, for example by
cycle racks or overhanging loads. Following a
severe impact or in the event of damage to the
bumpers, have the function of the radar sensors
checked at aqualified specialist workshop.
Blind Spot Assist may no longer work properly.
Monitoring area
In particular, the detection of obstacles can be
impaired if:
Rthere is dirt on the sensors or anything else
coveringt he sensors
Rthere is poor visibility, e.g. due to fog, heavy
rain, snow or spray
Rthere are narrow vehicles, e.g. motorcycles or
bicycles
Rthe road has very wide lanes
