Blind Spot Assist monitors the area up to 10 ft
(3.0 m) behind your vehicle and directly next to
your vehicle, as shown in the diagram. For this
purpose, Blind Spot Assist uses radar sensors in
the rear bumper.
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:
warnings may be issued in error when driving
R
close to crash barriers or similar solid lane
borders.
warnings may be interrupted when driving
R
alongside long vehicles, e.g. trucks, for a pro-
longed time.
Indicator and warning display
Yellow indicator lamp/red warning lamp
:
Blind Spot Assist is not active at speeds below
approximately 20 mph (30 km/h). Vehicles in
the monitoring range are then not indicated.
When Blind Spot Assist is activated, indicator
lamp : in the exterior mirrors lights up yellow
at speeds of up to 20 mph (30 km/h). At speeds
above 20 mph (30 km/h), the indicator lamp
goes out and Blind Spot Assist is operational.
If a vehicle is detected within the blind spot
monitoring range at speeds above 20 mph
(30 km/h), warning lamp : 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).
The yellow indicator lamp goes out if reverse
gear is engaged. In this event, Blind Spot Assist
is no longer active.
The brightness of the indicator/warning lamps
is adjusted automatically according to the ambi-
ent light.

Blind Spot Assist and you switch on the corre-
sponding turn signal, a double warning tone

signal remains on, vehicles detected are indica-
ted by the flashing of red warning lamp :.
