Lane Change Warning
Principle
The Lane Change Warning detects vehicles in
the blind spot, or if vehicles are approaching from
behind in the adjacent lane. A warning is issued
in various gradations in these situations.
General
From a minimum speed, two radar sensors in the
rear bumper monitor the area behind and next to
the vehicle.
The minimum speed is shown in the menu for
the Intelligent Safety Systems.
The system indicates when vehicles are in the
blind spot, arrow 1, or are approaching from the
rear in an adjacent lane, arrow 2.
The light in the exterior mirror illuminates at a
dimmed level.
Before changing lanes with the turn indicator
switched on, the system issues a warning in the
above situations.
The light in the exterior mirror flashes and the
steering wheel vibrates.

Safety
Safety notes
The system does not relieve you of your per‐
sonal responsibility to assess the visibility con‐
ditions and traffic situation correctly. There is a
danger of accidents. Adapt your driving style to
the traffic conditions. Observe the traffic situa‐
tion and intervene actively if the situation war‐
rants it.
Displays and warnings do not relieve you of
your personal responsibility. System limitations
can mean that warnings or system responses
are not issued or are issued too late, incorrectly
or without justification. There is a danger of ac‐
cidents. Adapt your driving style to the traffic
conditions. Observe the traffic situation and in‐
tervene actively if the situation warrants it.
