190Driving and operating● Driving on banked roads.
● Driving on road edges.
● Driving on roads with poor lane markings.
● Sudden lighting changes.
The system can not operate when no
lane marking is detected.
Lane keep assist Lane keep assist helps to avoid
crashes due to unintentional lane
departures. The front camera
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. Turn steering wheel in same
direction, if system steers not
sufficient. Turn steering wheel gently
into opposite direction, if lane change
is intended.
When crossing a lane marking
significantly, lane keep assist starts a
visual and acoustic warning.Unintended lane departure is
assumed
● without using turn signal
● without braking
● without acceleration
● without active steering.
Notice
The system is switched off during
detection of ambiguous lane
markings, e.g. in construction areas.
Notice
The system may be switched off if it
detects lanes which are too narrow,
too wide or too curved.
ActivationAfter ignition is switched on, lane
keep assist is activated. 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.
When the control indicator a in the
instrument cluster illuminates green,
the system is ready to assist.
The system is operational at vehicle
speeds between 40 mph and
112 mph and if lane markings are
available. The driver must hold the
wheel with both hands. The change of trajectory is not accompanied by
operation of the direction indicators.
The ESC system must be activated.
The system makes the correction to
the trajectory necessary to return the
vehicle to its initial path if it identifies
a risk of the vehicle involuntarily
crossing one of the lane markings
detected. The driver will then notice a
turning movement of the steering
wheel.
Driving and operating191The control indicator a flashes
during trajectory correction. In the
Driver Information Centre, the line of
the corrected side will be displayed in
orange.
If the driver wishes to maintain the
trajectory of the vehicle, he can
prevent the correction by keeping a
firm grip on the wheel (during an
avoiding manoeuvre, for example).
The correction is interrupted if the
direction indicators are operated.
While the direction indicators are on
and for a few seconds after switching
them off, the system considers that
any change of trajectory is voluntary and no correction is triggered during
this period.
If the system detects that the driver is not holding the wheel firmly enough
during an automatic correction of
trajectory, it interrupts the correction.
An alert is triggered to encourage the driver to take back control of the
vehicle.Deactivation
The system is deactivated by
pressing Ó during a few seconds; the
LED in the button illuminates. In the
Driver Information Centre, solid grey
lines are displayed.
Fault
The system performance may be
affected by:
● Windscreen not clean or affected
by foreign items, e.g. stickers
● Close vehicles ahead
● Banked roads
● Winding or hilly roads
● Road edges
● Roads with poor lane markings
● Sudden lighting changes
● Adverse environmental conditions e.g. heavy rain or
snow
● Vehicle modifications, e.g. tyres.Switch 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 (road condition and
surface, weather etc). The driver
has full responsibility to control the
