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‐
cles and are no substitute for attentive driving.
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
warning, a warning tone sounds and the warning
lamp in the outside mirror starts to flash.
This additional function is only available when
Blind Spot Assist is activated and up to a maxi‐
mum of three minutes after the ignition has
been switched off. The exit warning is no longer
available once the warning lamp in the outside
mirror flashes three times.
The exit warning is only an aid and not a substi‐
tute for the attention of vehicle occupants. The
responsibility for opening and closing the doors
and for leaving the vehicle remains with the vehi‐
cle occupants.
