Driving
Operating limits
The system may issue an alert when the
vehicle is travelling on a long, straight
road with smooth road surface even if the
driver thinks they are holding the steering
wheel correctly.
The system may not operate or may produce
unsuitable corrections to the steering in the
following situations:
– Poor visibility (insu󰀩cient road lighting,
snowfall, rain, fog).
– Dazzle (headlamps of an oncoming vehicle,
low sun, reections on a wet road surface,
leaving a tunnel, alternating light and shade).
– Windscreen area in front of the camera
dirty, misted up, frost-covered, snow-covered,
damaged or covered by a sticker.
– Lane markings eroded, partially hidden (snow,
mud) or multiple (roadworks, surface joints).
– Travelling in a tight bend.
– Winding roads.
– Presence of a tarmac joint on the road.
Risk of undesirable operation
The system should be deactivated in the
following situations:
– Driving with a "space-saver" type spare
wheel.
– When towing or with a bicycle carrier
attached to a towing device, particularly when
a trailer is not connected or the trailer is not
an approved type.
– Adverse weather conditions.
– Driving on slippery road surfaces (risk of
aquaplaning, snow, ice).
– In roadworks or toll booth areas.
– Driving on racing circuits.
– Driving on a rolling road.
Malfunction
In the event of a malfunction, the
Service warning lamp comes on
and this (orange) symbol appears on the
instrument panel, accompanied by the display of
a message and an audible signal.
Have it checked by a CITROËN dealer or a
qualied workshop.
Lane keeping assist
For more information, refer to the
General recommendations on the use
of driving and manoeuvring aids.
The system corrects the vehicle's trajectory by
alerting the driver as soon as it detects a risk of
involuntary lane departure or crossing of a verge
or hard shoulder (depending on version).
To do this, the system uses a camera, placed on
the upper part of the windscreen, identifying the
lane markings on the ground and the side of the
road (depending on version).
This system is particularly useful on
motorways and main roads.
Operating conditions
– Vehicle speed between 40 and 112 mph (65
and 180 km/h).
– Road marked with a central dividing line.
– Steering wheel held in both hands.
– Direction indicators not activated.
– ESC system activated and operational.
The system helps the driver only if there
is a risk of the vehicle unintentionally
wandering from the lane it is being driven in. It
does not manage the safe driving distance,
vehicle speed or braking.
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 (for example, if
the central dividing line disappears).
Operation
As soon as the system identies a risk of
involuntarily crossing one of the lane markings
detected on the ground or a lane boundary
(e.g. grass verge), it performs the trajectory
