Lane change alert
Additional to the side blind spot alert
3 181, lane change alert recognises
rapidly approaching vehicles from
behind on parallel lanes next to your
vehicle.
If the vehicle is equipped with lane
change alert, side blind spot alert is
always included.
The system alerts visually in each
exterior mirror when detecting rapidly
approaching vehicles from behind.
The radar distance sensors are
located in the rear bumper.
9 Warning
Lane change alert does not
replace driver vision.
Before changing a lane, always
check all mirrors, look over the
shoulder and use the turn signal.
When the system detects an
approaching vehicle from behind
which drives considerably faster, the
yellow warning symbol F will
illuminate in the relevant exterior
mirror. If the driver then activates the
turn signal, the warning symbol F
starts flashing yellow as a warning not
to change lanes.
Lane change alert is active at all
speeds.
When the vehicle is started, both
exterior mirror displays will briefly
come on to indicate that the system is
operating.
Detection zones
The system sensors cover a zone of
approx. 3.5 metres parallel on both
vehicle sides and approx.
three metres rearwards on side blind
zone alert (A) and approx. 70 metres
rearwards on lane change alert (B) on
parallel lanes. The zones start at each
exterior mirror. The height of the zone
is approx. between 0.5 metres and
two metres off the ground.
Deactivation
Activation or deactivation of the lane
change alert can be set in the vehicle
personalisation menu in the Info
display.
