Complementary to the catalytic converter, this filter makes an active contribution to the preservation of air quality
by the retaining of the unburnt pollutant particles. Black e xhaust fumes are thus no longer emitted.
Clogging of the particle filter
If there is risk of clogging, a message appears on the multifun ction display, accompanied by a sound signal and
lighting of the SERVICE warning lamp.
This alert tells you that the particle filter is starting to fill up (in conditions of urban driving of exceptionally long dura-
tion: low speeds, traffic jams etc.)
To regenerate the filter, it is advised to drive as soon as possible, wh en traffic conditions permit, at a speed of
60 km/h (around 40 mph) or more for at least five minutes (until the al ert message disappears).
If this alert persists, consult a CITROËN dealer.
Observation : After prolonged idling or driving at very low speeds, you may occa sionally notice water vapour be-
ing emitted from the exhaust when accelerating. This is of no consequence to the running of the vehicle or to the
environment.
Diesel fuel additive level
If the additive level becomes too low, a message appears on t he multifunction display, accompanied by a sound
signal and lighting of the SERVICE warning lamp. It is necessa ry to have the additive level topped up. Urgently
consult a CITROËN dealer.

This driving assistance device
alerts you if you are wandering from
your lane (continuous or dotted line
marking on the road surface).
It is designed especially for use
on motorways and dual carriage-
ways, operating only at speeds
above 80 km/h (approx. 50 mph).
Activation / Deactivation
A press on control A activates the
function, the warning lamp on the
control lights up.
A second press on control A de-
activates the function, the warning
lamp on the control goes out.
Whenever you start the engine,
the mode (activated/deactivated),
selected when you last switched
off the engine, is retained.
The driver must still remain attentive and in complete
control of the vehicle.
Operation
Provided you are travelling at over 80 km/h (approx. 50 mph), if you
cross
a lane marking, you are alerted by a vibration within the cush ion of your
seat :
- oriented to the right for crossing a lane marking to the righ t,
- oriented to the left for crossing a lane marking to the lef t.
The system does not alert you while your direction indicator is o perating,
nor for about 20 seconds after your direction indicator has stopp ed.
Note : In the event of an electronic malfunction, a message is displ ayed,
the SERVICE warning lamp comes on and a sound signal is heard. Con -
tact a CITROËN dealer.
Observations : This device is designed to identify traffic lane markings.
In certain specific instances, it may trigger an unwanted alert, for examp le
when you cross a direction arrow or some other random marking.
The effectiveness of the system may be temporarily affected by condi tions
external to the vehicle :
• Detection of lanes made difficult by:
- Markings that are worn or erased.
- Insufficient contrast with the surface of the road.
• Masking of the sensors due to:
- Driving in snow or heavy rain.
- Driving on roads covered with mud or surface water.
If the system is ineffective for a prolonged period, contact a CITROËN
dealer.

Electrical control
From the driver’s seat position,
the controls siutated on the door
enable the vehicle’s electric win-
dows to be actioned.
Note : The windows can also be
operated for a short time after the
ignition has been switched off (in-
cluding after the front doors have
been opened).
Sequential control
An action to the first notch on the
control starts a window movement
which stops when the control is
released. A press for about one
second on the control will close
or open the window fully, a further
press will stop the movement. PAY ATTENTION TO WHERE CHILDREN ARE
WHEN OPERATING THE ELECTRIC WINDOWS.
- Always remove the key from the ignition when leaving the vehicl e,
even for a short time.
- When the driver is actioning the controls for the passenger wi ndows,
he must make sure that no-one is obstructing the windows from
closing properly.
- The driver should ensure that the passengers use the windows correctly.
- If any person should be at risk of becoming trapped by the op eration
of the windows, you must reverse the movement of the glass. For t hat,
reverse the position of the control concerned. This is for deactivating operation of the electric
windows and opening
of the rear doors from the rear seat positions.
It is activated by a press on the control A located on the window
control panel or by an action on the locks of the rear doors.
The warning lamp in the instrument panel comes on temporarily.
Each time you switch on the ignition, the warning lamp lights up for a short time.
It is still possible to open the doors from the outside and to operate the rear
windows from the front seat positions.
Anti-pinch
An anti-pinch device will stop the glass from rising. If it meet
s an obstacle,
it goes back down.
After a battery disconnection or following a malfun ction, you have to
re-initialise the anti-pinch function for each window :
- Use the control to open the window fully, then attempt to close it. It will
rise only a few centimetres.
- Pull again on the control until the window closes fully. Once the window
is closed, sustain the press on the control for one second.
Warning : During this operation, the anti-pinch protection is inoperat ive.

Sensors
The automatic regulation of the air
conditioning inside the cabin uses
a number of sensors that relieve
you of the need to make adjust-
ments outside the displayed tem-
perature.
Be careful not to obstruct the sun-
light sensor located on the dash-
board.
Air inlet
Check that the exterior grille for
the air inlet, at the bottom of the
windscreen, is clean and free of
dead leaves, snow, etc.
Air vents
The air vents to the face have grilles
and thumbwheels so that you can
adjust the air flow and direction
(up-down, right-left).
Air circulation
Air vents on the floor underneath
the front seats provide enhanced
heating for the rear seat positions :
take care not to obstruct them.
Dust filter / odour filter
(active carbon)
There is a filter for excluding odours
and dust.
This filter has to be changed in
accordance with the vehicle main-
tenance schedule (see the Main-
tenance Guide). Air conditioning
To ensure that your system oper-
ates correctly, it is recommended
to have it checked regularly.
Water arising from condensation
in the air conditioning drains away
through a hole provided for this
purpose. A pool of water may thus
form under the vehicle when sta-
tionary.
To keep the air conditioning com-
pressor well sealed, it is essential
to operate the air conditioning at
least once in every month.
To be effective, the air condition-
ing should only be used with the
windows closed.
If after a lengthy stop in bright
sunlight the interior temperature is
excessive, air the passenger com-
partment by opening the windows
for a few moments, then close
them again.
The air conditioning operates by
using power from the engine. This
results in a slight increase in fuel
consumption.
