6Operation
The system starts automatically when moving
off.
A check of the operating conditions takes place: these two indicator
lamps come on in the instrument panel.
When these conditions are met, these two
indicator lamps go off. The system is activated.
If the operating conditions are not met, the
system is activated but is no longer effective.
This is signalled by the fixed illumination of these
two warning lamps in the instrument panel.
Operating conditions
Once engaged, the system is active only when
these operating conditions are met:
– The vehicle is moving forwards.
– No malfunction of the vehicle is detected.
– The speed of the vehicle is equal to or greater
than approximately 37 mph (60 km/h).
– The longitudinal marking of the traffic lanes is
clearly visible.
– The visibility conditions are clear.
– The trajectory is in a straight line (or in the
case of bends, they are wide).
– The field of vision is sufficiently clear (the
safety distance with the vehicle ahead is
respected).
– In the event of a lane departure, the direction
indicator corresponding to the direction (right or
left) of the departure has not been operated. –
The trajectory of the vehicle is consistent with
the road layout.
Deactivation / Reactivation



► Press this button to deactivate / reactivate the
function.
Deactivation is signalled by the illumination of
the button indicator lamp.
Upon reactivation, the two instrument panel
indicator lamps remain lit and fixed until the
speed reaches 37 mph (60 km/h).
The state of the system stays in the memory
when switching off the ignition.
Detection
If a deviation in direction is detected on
the left or the right, the indicator lamp on
the corresponding side flashes in the instrument
panel, accompanied by an audible signal.
No warning is transmitted while the direction
indicator is activated and for approximately 20
seconds after the direction indicator is switched
off.
A warning may be transmitted if a direction
marking (arrow) or non-standard marking
(graffiti) is crossed.
The detection may be impeded: – if the markings on the road are worn,
– if there is little contrast between the
markings on the road and the road surface.
The system is automatically deactivated if the Stop & Start function is active. The
system will restart and re-enable recognition
of the operating conditions after the vehicle is
started.
The system may suffer interference or not work correctly:
– when the vehicle is carrying an excessive
load (even more so if it is poorly balanced);
– under poor visibility conditions (rain, fog,
snow, etc.);
– under poor light conditions (dazzling
sunlight, darkness, etc.);
– if the windscreen is dirty or damaged near
the camera;
– if the ABS, DSC, ASR or Intelligent Traction
Control systems are out of order.

the ignition off).
If the engine cover is to be removed /
refitted, handle it with care to avoid
damaging the mounting clips.
Used products
Avoid prolonged contact of used oil or fluids with the skin.
Most of these fluids are harmful to health and
very corrosive.
Do not discard used oil or fluids into
sewers or onto the ground.
Empty used oil into the containers reserved
for this purpose at a CITROËN dealer or a
qualified workshop.
Engine oil
The level is checked, with the engine having been switched off for at least 30
minutes and on level ground, using the dipstick.
It is normal to top up the oil level between two
services (or oil changes). It is recommended
that you check the level, and top up if necessary,
every 3,000 miles (5,000 km).
In order to maintain the reliability of the
engine and emissions control system,
never use additives in the engine oil.
