Blind Spot Assist and Active Blind Spot
Assist with exit warning
Function of Blind Spot Assist and Active
Blind Spot Assist with exit warning
Blind Spot Assist and Active Blind Spot Assist
use two lateral, rear-facing radar sensors to
monitor the area up to 130 ft (40 m) behind and
10 ft (3 m) next to your vehicle.
If a vehicle is detected at speeds above approx‐
imately 8 mph (12 km/h) and this vehicle subse‐
quently enters the monitoring range directly next
to your vehicle, the warning lamp in the outside
mirror lights up red.
If a vehicle is detected close to the side of your
vehicle, the red warning lamp in the outside mir‐
ror flashes. If you switch on the turn signal indi‐
cator in the corresponding direction, a warning
tone sounds once. If the turn signal indicator
remains switched on, all other detected vehicles
are indicated only by the flashing of the red
warning lamp.
If you overtake a vehicle quickly, no warning is
given.
& WARNING Risk of accident despite Blind
Spot Assist
Blind Spot Assist does not react to vehicles
approaching and overtaking you at a greatly
different speed.
As a result, Blind Spot Assist cannot warn
drivers in this situation.
Always pay careful attention to the traf‐

fic situation and maintain a safe dis‐
tance at the side of the vehicle.
Blind Spot Assist and Active Blind Spot Assist
are only aids. They may fail to detect some vehi‐

Always ensure that there is sufficient distance to
the side for other road users and obstacles.
Exit warning
The exit warning is an additional function of
Blind Spot Assist and can warn vehicle occu‐
pants about approaching vehicles when leaving
the vehicle when stationary.
& WARNING Risk of accident despite exit
warning
The exit warning reacts neither to stationary
objects nor to vehicles approaching you at a
greatly different speed.
As a result, the exit warning cannot warn
drivers in these situations.
Always pay particular attention to the
#
traffic situation when opening the doors
and make sure there is sufficient clear‐
ance.
If there is a vehicle in the monitoring range, this
is indicated in the outside mirror. If a vehicle
occupant opens the door on the side with the
