Lane keep assist Lane keep assist helps to avoid
crashes due to unintentional lane
departures. A front camera located at the top of the windscreen observes
the lane markings between which the
vehicle is driving. If the vehicle
approaches a lane marking, the
steering wheel is gently turned to
position the vehicle back into the lane. The driver will then notice a turning
movement of the steering wheel. Turn
steering wheel in same direction, ifsystem steers not sufficient. Turn
steering wheel gently into opposite
direction, if lane change is intended.
When the system steers to correct the trajectory of the vehicle, a flashes
yellow in the instrument cluster.
A warning message in the Driver
Information Centre accompanied by a warning chime alerts the driver when
immediate driver´s action is required.
Unintended lane departure is not
assumed by the system when the turn lights are operated and during 20 s
after turn lights have been switched
off.
Note
The system may be switched off if it
detects lanes which are too narrow,
too wide or too curved.
Following preconditions have to be
fullfilled:
● vehicle speed must be between 65 km/h and 180 km/h
● the driver must hold the steering wheel with both hands● the change of trajectory is notaccompanied by operation of theturn signals
● the Electronic Stability Control is activated and not in operation
● the vehicle is not connected to a trailer or an electric bicycle carrier
● normal driving behaviour (system
detects dynamic driving style, i.e. pressure on the brake or
accelerator pedal)
● roads with poor lane markings
● no spare wheel is used
● the driver needs to be active during the correction
● the vehicle is not driven in a tight
corner
202Driving and operatingActivation
If the system is activated, the LED in
the button Ó is not illuminated. To
activate the system when the system
is deactivated, press Ó.
The system is operational at vehicle
speeds between 65 km/h and
180 km/h and if lane markings are
detectable. The driver must hold the
steering wheel with both hands. The Electronic Stability Control system
must be activated.
The control indicator a flashes
yellow during trajectory correction.
If the driver wishes to maintain the
trajectory of the vehicle, he can
prevent the correction by keeping a
firm grip on the steering wheel, e.g.
during an avoiding manoeuvre. The correction is interrupted if the turn
lights are operated.
There is no correction triggered when
the turn lights are operated and
during a few seconds after turn lights
have been switched off.
If the system detects that the driver is not holding the steering wheel firmly
enough during an automatic
correction of trajectory, it interrupts
the correction. A warning message in
the Driver Information Centre
accompanied by a warning chime
alerts the driver when immediate
driver´s action is required.
If the side blind spot alert is activated
and the driver is about to change the
lane, the system corrects the
trajectory of the vehicle despite the
activation of the turn lights if another
vehicle is detected in the side blind
spot zone.Deactivation
To deactivate the system, press and
hold Ó. Deactivation of the system is
confirmed by the illuminated LED in
the button. In the Driver Information
Centre solid grey lines are displayed.
Recommended deactivationIt is recommended to deactivate the
system in the following situations:
● Road surface in poor condition
● Unfavourable climatic conditions
● Slippery surfaces, e.g., ice
The system is not designed for driving
in the following situations:
● Driving on a speed circuit
● Driving with a trailer
● Driving on a rolling stand
● Driving on unstable surfaces
Driving and operating203Fault
In the event of a fault, a and H
appear in the instrument panel,
accompanied by a display message
and a warning chime. Contact a
dealer or a qualified workshop to have the system checked.
System limitations The system performance may be
affected by:
● windscreen not clean or affected by foreign objects, e.g. stickers
● close vehicles ahead
● banked roads
● narrow, winding or hilly roads
● road edges
● sudden lighting changes
● adverse environmental conditions, e.g. heavy rain or
snow
● vehicle modifications, e.g. tyresSwitch off the system if the system is
disturbed by tar marks, shadows,
road cracks, temporary or
construction lane markings, or other
road imperfections.9 Warning
Always keep your attention on the
road and maintain proper vehicle
position within the lane, otherwise
vehicle damage, injury or death
could occur.
Lane keep assist does not
continuously steer the vehicle.
The system may not keep the
vehicle in the lane or give an alert,
even if a lane marking is detected.
The steering of the lane keep
assist may not be sufficient to
avoid a lane departure.
The system may not detect hands-
off driving due to external
influences like road condition and
surface and weather. The driver has full responsibility to control the
vehicle and is always required to
keep the hands on the steering
wheel while driving.
Using the system while towing a
trailer or on slippery roads could
cause loss of control of the vehicle
and a crash. Switch the system off.
Driver alert
The driver alert system monitores the driving time and the vigilance of the
driver. Monitoring the vigilance of the
driver is based on the trajectory
variations of the vehicle compared to
the lane markings.
The system includes a driving time
alert combined with driver drowsiness detection.
9 Warning
The system cannot replace the
need for vigilance on the part of
the driver. Taking a break is
recommended as soon as feeling tired or at least every two hours.
Do not take the steering wheel
when feeling tired.
204Driving and operatingActivation or Deactivation
The system can be activated or
deactivated in the vehicle
personalisation 3 118.
The state of the system stays in
memory when the ignition is switched
off.
Driving time alert The driver gets notified by a pop-up
reminder symbol € in the Driver
Information Centre simultaneously
with an acoustic alert if the driver has
not taken a break after 2 hours of
driving at a speed above 65 km/h. The
alert is repeated hourly until the
vehicle is stopped, no matter how
vehicle speed evolves.The counting of driving time alert is
reset if one of the following conditions is met:
● The vehicle has been stationary for more than 15 minutes with the
engine running.
● The ignition has been switched off for a few minutes.
● The driver's seat belt has been unfastened and the driver's door
is open.
Note
If the vehicle speed drops below
65 km/h, the system is paused. The
driving time is counted again once
the speed is above 65 km/h.
Driver drowsiness detection
The system monitors the driver's level
of vigilance. A camera at the top of the
windscreen detects variations in
trajectory compared to the lane
markings. This system is particularly suited to fast roads (speed higher
than 65 km/h).
If the trajectory of the vehicle
suggests a certain level of
drowsiness or inattention by thedriver, the system triggers the first
level of alert. The driver is notified by
a message and an audible signal is
given.
After three first level alerts, the
system triggers a new alert with a
message, accompanied by a more
pronounced audible signal.
In certain driving conditions (poor
road surface or strong winds), the
system may give alerts independent of the driver's level of vigilance.
The driver drowsiness detection is reinitialised when the ignition has
been switched off for a few minutes or the speed remains below 65 km/h for a few minutes.
System limitations
In the following situations, the system
may not operate properly or even not operate at all:
● poor visibility caused by inadequate lighting of the
roadway, falling snow, heavy
rain, dense fog etc.
