Lane Keep Assist
1
Fig. 104: Windshield camera
Using the front camera A and within the limits of the
system, Lane Keep Assist detects the course of the
road ahead based on the lane markings. When the
vehicle approaches a detected lane marking and is in
danger of leaving the driving lane, the system ini-
tiates corrective steering intervention that helps to
keep the vehicle in the lane. Steering intervention is
displayed visually to the driver in the status display.
The driver can override the steering intervention at
any time.
If the vehicle crosses a lane marking without acti-
vating a turn signal, the system alerts the driver
acoustically. For this purpose, the acoustic warning
must be switched on in the
ASSIST menu on
the PCM.
The system is designed for driving on highways and
well-surfaced country roads and works in a speed
range of approx. 40 mph (65 km/h) – 156 mph
(250 km/h). The operative system does not issue a
warning or steer if the driver activates a turn signal
before crossing a lane marking. In these situations,
the system interprets the lane change as intentional.
b b Vehicles with Lane Change Assist:
If the vehicle is equipped with Lane Change Assist,
the driver is warned through corrective steering
intervention back into the correct lane when chang-
ing lanes in a potentially critical situation. This also
happens if the turn signal is activated for the rele-
vant direction. At the same time, the relevant side on
the status display is marked red during the steering
intervention and an acoustic warning (if activated) is
emitted when the lane markings are crossed.
WARNING
Lack of attention
The driver remains responsible at all times when
driving, e.g. staying in lane, even if Lane Keep Assist
is on. The system does not replace the driver's
attentiveness.
– The system can help to keep the vehicle in the
lane within the limits of the system, but it does
not drive it. Keep your hands on the steering
wheel at all times order to always by ready to
steer. If a warning appears on the instrument
cluster, take over control of the vehicle
immediately.
– In the case of heavy braking, for example, the
corrective steering interventions may not take
place.
– In the case of active steering by the driver, cor-
rective steering intervention can be reduced or
may not take place.
– It is possible that not all lane markings will be
detected. Steering intervention can only take
place on the side where a lane marking has been
detected.
– Other road structures or objects may be incor-
rectly identified as lane markings. This can lead
to unexpected or missing steering interventions/
acoustic warnings.
– Corrective steering intervention alone may not
be sufficient to keep the vehicle in the driving
lane in the case of track ruts, winding roads, in-
clined road surfaces or crosswind. The driver
must actively steer in such situations.
e Never use Lane Keep Assist in the following
situations:
– When increased attention is required on the
part of the driver.
– During sporty driving.
– In adverse weather conditions (e.g. fog, snow
or heavy rain).
– Under unfavorable road conditions (including
bad roads, pot holes, dirty road surfaces).
– In roadworks areas.
– When approaching humps and dips.
– In urban traffic.
– On winding and narrow country roads.
e Drive with extreme care.
e Always pay attention to the traffic situation and
the vehicle surroundings.
e Adapt your driving speed to road and weather
conditions.
e Do not attach any objects to the steering wheel.
WARNING
Failure of camera to de-
tect the lane
The camera's view can be impaired by different in-
fluencing factors (e.g. rain, snow, ice, heavy water
spray, oncoming headlights or damage). Sometimes,
the camera cannot detect the lane markings, or
cannot detect them correctly. When this happens,
no steering intervention or an unexpected steering
