Mercedes-Benz Sprinter 2019 Operating Instructions Manual page 151

If a vehicle is detected above speeds of approx‐
imately 7.5 mph (12 km/h) and this vehicle sub‐
sequently enters the monitoring range directly
next to your vehicle, the warning lamp in the out‐
side mirror lights up red.
%
When a trailer is connected, the radar sen‐
sor's field of vision may be impaired, thereby
making limited monitoring possible. Always
pay careful attention to the traffic situation
and maintain a safe distance at the side of
the vehicle.
If a vehicle is detected close to your vehicle in the
lateral monitoring range and you switch on the
turn signal indicator in the corresponding direc‐
tion, a warning tone sounds. The red warning
lamp in the outside mirror flashes. If the turn sig‐
nal indicator remains switched on, all other
detected vehicles are indicated only by the flash‐
ing of the red warning lamp.
If you overtake a vehicle quickly, no warning is
given.
Exit warning
The exit warning is an additional function of Blind
Spot Assist and warns vehicle occupants when
leaving the vehicle about any approaching vehi‐
cles.
& 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 driv‐
ers in these situations.
Always pay particular attention to the
#
traffic situation when opening the doors
and make sure there is sufficient clear‐
ance.
%
An exit warning is not issued for sliding doors
and rear-end doors.

ing the vehicle.
