Lane Departure Warning System; Conditions For Operation - CITROEN C4 Spacetourer Handbook

The driver can maintain control of the
vehicle at any time by sharply turning
the steering wheel and/or pressing the
accelerator pedal.
Operation of the function may be felt by
slight vibration in the brake pedal.
If the vehicle comes to a complete stop,
the automatic braking is maintained for
1 to 2 seconds.
Malfunction
In the event of a fault with the
system, you are alerted by the
illumination of this warning lamp,
accompanied by the display of
a message and an audible signal.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
Lane Departure Warning
System
Using a camera located at the top of the
windscreen to identify lane markings on the
ground, the system corrects the trajectory of
the vehicle while alerting the driver if it detects
a risk of involuntary crossing of a line.
This system is particularly useful on motorways
and main roads.

Conditions for operation

The speed of the vehicle must be between
40 mph and 112 mph (65 km/h and 180 km/h).
The driver must hold the steering wheel with
both hands.
The change of trajectory must not be
accompanied by operation of the direction
indicators.
The ESC system must be activated and fault-
free.
This system is a driving aid that cannot,
in any circumstances, replace the
driver's own vigilance. The driver must
remain in control of the vehicle under all
circumstances.
The system helps the driver only when
there is a risk of the vehicle involuntarily
wandering from the lane it is being driven
in. It does not manage the safe driving
distance, the speed of the vehicle or the
brakes.
The driver must hold the steering wheel
with both hands in a way that allows
control to be maintained in circumstances
where the system is not able to intervene
(if lane markings disappear, for example).
It is necessary to observe the driving
regulations and take a break every two
hours.
Operation
Once the system identifies a risk of the vehicle
involuntarily crossing one of the lane markings
detected, it makes the correction to the
trajectory required to return the vehicle to its
initial path.
The driver will notice a turning movement of the
steering wheel.
This warning lamp flashes during
trajectory correction.
