Safety
Lane Change Warning
Principle
Lane Change Warning detects vehicles in the
blind spot, or if vehicles are approaching from
behind in the adjacent lane.
The light in the exterior mirror warns in differ-
ent increments.
General
The system is operational after a minimum
speed has been reached and uses radar sen-
sors to monitor the area behind and adjacent
to the vehicle.
The minimum speed is country-specific and
displayed in the Lane Change Warning menu.
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.
In the above situations, the system issues a
warning before a lane change with the turn in-
dicator activated. The light in the exterior mir-
ror flashes and the steering wheel vibrates.
When turning at a speed of up to approx.
20 km/h/12 mph, the steering wheel will not
vibrate.
Safety information
Follow the safety information in the Chapter
"Collision warning systems".
