● the vehicle had a rear-end accident
● there are extreme temperature changes
Lane departure warning The lane departure warning system
uses a front camera to observe the
lane markings between which the
vehicle is driving. The system detects
lane changes and warns the driver in
the event of an unintended lane
change via visual and acoustic
signals.
Criteria for the detection of an
unintended lane change are:
● no operation of turn and lane- change signals
● no active steering
If the driver is performing these
actions, no warning will be issued.Activation
The lane departure warning system is activated by pressing  ì in the roof
console; LED in the button
extinguishes to indicate that the
system is switched on.
When control indicator  ì 3  97
illuminates in the instrument cluster,
the system is ready to operate. A
corresponding message also
appears in the Driver Information
Centre  3 101.
Control indicator  ì extinguishes
when the system is not ready to warn the driver.
The system is only operable at
vehicle speeds above approx.
37 mph and if lane markings are
available and detected.
