severe impact or in the event of damage to the
bumpers, have the function of the radar sensors
checked at a qualified specialist workshop.
Blind Spot Assist may no longer work properly.
Monitoring area In particular, the detection of obstacles can be
impaired if: R
there is dirt on the sensors or anything else
covering the sensors R
there is poor visibility, e.g. due to fog, heavy
rain, snow or spray R
there are narrow vehicles, e.g. motorcycles or
bicycles R
the road has very wide lanes R
the road has narrow lanes R
you are not driving in the middle of the lane R
there are barriers or similar lane borders
Vehicles in the monitoring range are then not
indicated.
Blind Spot Assist monitors the area up to 10 ft
(3 m) behind your vehicle and directly next to
your vehicle, as shown in the diagram.
If the lanes are narrow, vehicles driving in the
lane beyond the lane next to your vehicle may be
indicated, especially if the vehicles are not driv-
ing in the middle of their lane. This may be the
case if there are vehicles driving at the inner
edge of their lanes. Due to the nature of the system: R
warnings may be issued in error when driving
close to crash barriers or similar solid lane
borders. R
the warning is canceled when driving for an
extended period next to long vehicles, such as
trucks.

Warning display
Blind Spot Assist is not active at speeds below
approximately 20 mph (30 km/h). Vehicles in
the monitoring range are then not indicated.
If a vehicle is detected within the blind spot
monitoring range at speeds above 20 mph
(30 km/h), warning lamp C on the correspond-
ing side lights up red. This warning is always
emitted when a vehicle enters the blind spot
monitoring range from behind or from the side.
When you overtake a vehicle, the warning only
occurs if the difference in speed is less than
7 mph (12 km/h).
If you select the reverse gear, Blind Spot Assist
is not operational.
The brightness of the warning lamps is auto-
matically adapted to the brightness of the sur-
roundings.
Collision warning
If a vehicle is detected in the monitoring range of
Blind Spot Assist and you switch on the corre-
sponding turn signal, a double warning tone
sounds. Red warning lamp C flashes. If the turn
signal remains on, vehicles detected are indica-
ted by the flashing of red warning lamp C .
There are no further warning tones.Driving systems 217

you then switch on th e correspondin g tur n sig-
nal to chang e lane, you will also receiv e an opti-
cal and audibl e warning. If a ris k of lateral colli-
sion is detected, corrective brakin g may help
you avoid a collision . Befor e a course-correcting
brak e application , Active Blind Spot Assis t eval -
uates th e spac e in th e direction of travel and at
th e side s of th e vehicle. Fo r this, Active Blind
Spot Assis t uses th e forward-facing rada r sen -
sors.
Active Blind Spot Assis t support s you from a
speed of approximately 20 mph (30 km/h).
