R
if vehicles traveling at a much faster speed
approach and then overtake
Active Blind Spot Assist may not give warnings
or intervene in such situations.
#
Always pay careful attention to the traffic
situation and maintain a safe distance at
the side of the vehicle.
Observe the notes on driving systems and your
responsibility; you may otherwise fail to recognize
dangers (
/
page 176).
Exit warning
The exit warning is an additional function of Blind
Spot Assist and can warn vehicle occupants about
approaching vehicles when leaving the vehicle
when stationary.
&
WARNING Risk of accident despite exit
warning
The exit warning neither reacts to stationary
objects nor to persons or road users
approaching you at a greatly differing speed.
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 occu-
pant 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 available only when
Blind Spot Assist is active. When the exit warning
is activated, it can warn vehicle occupants for up
to three minutes after switching the vehicle 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.
System limits
Blind Spot Assist and Active Blind Spot Assist may
be limited in the following situations, in particular:
R
if there is dirt on the sensors or the sensors
are obscured
R
in poor visibility, e.g. due to fog, heavy rain or
snow
R
if there are narrow vehicles, e.g. bicycles or
motorbikes
R
if the road has very wide or narrow lanes
R
if vehicles are not driving in the middle of their
lane
Warnings may be issued in error when driving
close to crash barriers or similar continuous lane
borders. Always make sure that there is sufficient
distance to the side for other traffic or obstacles.
Warnings may be interrupted when you are driving
alongside long vehicles (e.g. trucks) for a pro-
longed time.
Blind Spot Assist is not operational when reverse
gear is engaged.
