Lane Departure Warning - BMW 3 SERIES SEDAN Owner's Manual

Intervene immediately by braking or making an
evasive maneuver.
Braking intervention
The warning prompts the driver himself to in‐
tervene. During the warning, the maximum
braking force is used, even with light pressure
on the brake pedal. In addition, if there is a risk
of collision, the system can assist with a slight
braking intervention. The intervention can
bring a vehicle traveling at slow speed to a
complete stop.
Manual transmission: During a braking inter‐
vention up until reaching a complete stop, the
engine may be shut down.
The braking intervention is executed only if
DSC Dynamic Stability Control is switched on
and Dynamic Traction Control DTC is acti‐
vated.
The braking intervention can be interrupted by
pressing on the accelerator or by actively mov‐
ing the steering wheel.
When towing or tow-starting the vehicle,
switch off the pedestrian warning to prevent
undesired interventions.
System limits
Be alert
Due to system limitations, warnings may
be not be issued at all, or may be issued late or
improperly. Therefore, always be alert and
ready to intervene; otherwise, there is the dan‐
ger of an accident occurring.◀
Detection range
The detection capability of the camera is lim‐
ited.
This may result in the warning not being is‐
sued or being issued late.

be detected:
▷ Partially covered pedestrians.

because of the viewing angle or contour.

not be available in the following situations:

fall.

▷ If the camera view field or the front wind‐
shield are dirty or covered.

Lane departure warning

The concept
Starting at a specific speed, this system alerts
you when the vehicle on streets with lane
markings is about to leave the lane. Depending
on the country-specific version of the vehicle,
the speed is between 35 mph/55 km/h and
45 mph/70 km/h. If the system is switched on
below this speed, a message appears in the in‐
strument cluster.
The steering wheel begins vibrating gently in
the event of warnings. The time of the warning
may vary depending on the current driving sit‐
uation.
The system does not provide a warning if the
turn signal is set before leaving the lane.
