Air conditioning
To ensure that your system operates
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 pur-
pose. A pool of water may thus form
under the vehicle when stationary.
To keep the air conditioning com-
pressor well sealed, it is essential to
operate the air conditioning at least
once in every month.
Regardless of the season, the air
conditioning is useful, since it re-
moves humidity and condensation.
To be effective, the air conditioning
should only be used with the windows
closed.
If after a lengthy stop in bright sunlight
the interior temperature is excessive,
ventilate the passenger compartment
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.
Dust filter/Odour filter
(active carbon)
There is a fi lter for excluding odours
and dust.
This fi lter has to be changed in ac-
cordance with the vehicle servicing
schedule (see "Maintenance and
Warranty Guide").
Air circulation
Maximum comfort is obtained when
there is a good distribution of air in
the passenger compartment, both in
the front and in the rear.
For optimum operating effi ciency,
take care not to obstruct the air out-
lets under the front seats.
Air vents
The face-level air vents have grilles
and thumbwheels to adjust the air
fl ow and direction (up-down, right-
left).
The automatic regulation of the air
conditioning, inside the cabin, uses
the sunshine sensor located on the
dashboard behind the instrument
panel.
Be careful not to obstruct it.

Rear view mirror
Adjustable mirror providing a central
rearward view.
Equipped with an anti-dazzle system,
useful in poor light.
Manual day/night model
Adjustment

 Adjust the mirror so that the
glass is directed correctly in the
"day" position.
Day/night position

 Pull the lever to change to the
"night" anti-dazzle position.

 Push the lever to change to the
normal "day" position. By means of a sensor, which mea-
sures the light from the rear of the
vehicle, this system automatically
and progressively changes between
the day and night uses.
It has an anti-dazzle system which
darkens the mirror glass: this reduc-
es any driver discomfort caused by
the light beam of following vehicles,
the sun...
In order to guarantee optimum vis-
ibility during your manoeuvres, the
mirror lightens automatically when
reverse gear is engaged.
STEERING WHEEL ADJUSTMENT
The height and reach of the steer-
ing wheel can be adjusted to adapt
the driving position to the size of the
driver.
Adjustment

 First, adjust the driver's seat to
the most suitable position.

 When stationary , pull the con-
trol lever to unlock the steering
wheel adjustment.

 Adjust for height and reach.

 Push the control lever to lock the
steering wheel adjustment.
After locking, if you press fi rmly on
the steering wheel, a slight click may
be heard.
As a safety precaution, the mirrors
must be adjusted to reduce the
"blind spot".
Automatic day/night model
As a safety precaution, these op-
erations must only be carried out
while the vehicle is stationary.

Model with rear foglamp only Model with front and rear
foglamps
In good or rainy weather, both day and night, the front foglamps and the rear
foglamp are prohibited. In these situations, the power of their beams may
dazzle other drivers. They should only be used in fog or snow.
In these weather conditions, it is your responsibility to swit ch on the foglamps
and dipped beam headlamps manually as the brightness sensor may d etect
suffi cient light.
Do not forget to switch off the front foglamps and the re ar foglamp when they
are no longer necessary. Switching off of the lamps when
the ignition is switched off
On switching off the ignition, all of the
lamps turn off immediately, except
for dipped beam if guide-me-home
lighting is activated.
Switching on the lamps after
the ignition is switched off
To reactivate the lighting control, ro-
tate ring
A to the "0" position - lamps
off, then to the desired position.
On opening the driver’s door a
temporary audible signal warns the
driver that the lighting is on.
The lamps, with the exception of
the sidelamps, switch off automati-
cally after a maximum duration of
thirty minutes to prevent dischar-
ging of the battery.
In some climatic conditions (e.g.
low temperature or humidity), the
presence of misting on the internal
surface of the glass of the head-
lamps and rear lamps is normal;
it disappears after the lamps have
been on for a few minutes.

headlamps
The sidelamps and dipped beam
headlamps are switched on automati-
cally, without any action on the part of
the driver, when a low level of external
light is detected or in certain cases of
activation of the windscreen wipers.
As soon as the brightness returns to a
suffi cient level or after the windscreen
wipers are switched off, the lamps are
switched off automatically.

TYRE UNDER-INFLATION DETECTION
Sensors fi tted in each valve check
the tyre pressure during driving and
trigger a warning in the event of
malfunction (speed above 12 mph
(20 km/h)).
Under-infl ated tyre The tyre under-infl ation detection
system is an aid to driving which
does not replace the vigilance or
responsibility of the driver. Puncture
The service warning lamp
comes on in the instru-
ment panel, accompanied
by an audible signal and
a message on the multi-
function screen locating
the wheel concerned.
Check the tyre pressures as soon as
possible. This check must be carried
out when the tyres are cold. The
STOP warning lamp
comes on in the instru-
ment panel, accompanied
by an audible signal and
a message on the multi-
function screen locating
the wheel concerned.
Stop immediately, avoiding any sud-
den movement of the steering wheel
and the brakes.
Change the damaged wheel (punctured
or very defl ated tyre), and have the tyre
pressure checked as soon as possible.
Sensor(s) not detected or faulty
The service warning
lamp comes on in the
instrument panel, ac-
companied by an audible
signal and a message on
the multifunction screen
locating the wheel or wheels which
are not detected or indicating a fault
in the system.
Have the faulty sensor(s) checked
by a CITROËN dealer. All repairs and changing of tyres
on a wheel fi tted with this system
must be carried out by a CITROËN
dealer.
If, when changing a tyre, you in-
stall a wheel which is not detected
by your vehicle (example: fi tting
of snow tyres), you must have the
system reinitialised by a CITROËN
dealer.
This system does not avoid the
need to have the tyre pressures
checked regularly (refer to the
"Technical data - § Identifi cation
markings" section) to ensure that
the optimum dynamic performance
of the vehicle is maintained and
prevent premature wear of the
tyres, particularly in arduous driv-
ing conditions (heavy load, high
speed).
The tyre pressures must be
checked cold, at least once a
month. Remember to check the
pressure of the spare wheel.
The tyre under-infl ation detection
system may experience temporary
interference due to electro-magnetic
signals on a frequency close to that
used by the system.
This message is also displayed
when one of the wheels is away
from the vehicle (being repaired) or
when one or more wheels without a
sensor are fi tted.
The spare wheel is not fi tted with a
sensor.
