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 win-
dows closed.
If after a lengthy stop in bright sun-
light the interior temperature is ex-
cessive, ventilate the passenger
compartment by opening the win-
dows 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.

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.
F o r o p t i m u m o p e r a t i n g e f fi c i e n c y ,
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 o w a n d d i r e c t i o n ( u p - d o w n , r i g h t -
left).
The automatic regulation of the air
conditioning, inside the cabin, uses
the sunlight sensor located on the
dashboard behind the instrument
panel.
Be careful not to obstruct it.

Lighting on buzzer
The triggering of an audible signal
when a front door is opened warns
the driver that he has forgotten to
switch off his vehicle's lamps, with
the ignition off and in manual light-
ing mode.
In this case, switching off the lamps
stops the audible signal.
With the ignition off, if the dipped
headlamps remain on, they will
switch off automatically after thirty
minutes to prevent discharging of
the battery.

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 (punc-
t u r e d o r v e r y d e fl a t e d t y r e ) , a n d
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
o n a w h e e l fi t t e d w i t h t h i s s y s t e m
must be carried out by a CITROËN
dealer.
If, when changing a tyre, you in-
stall a wheel which is not detected
b y y o u r v e h i c l e ( e x a m p l e : fi t t i n g
of snow tyres), you must have the
system reinitialised by a CITROËN
dealer.
This system does not eliminate
the need to have the tyre pres-
sure checked regularly (refer to the
" T e c h n i c a l d a t a - § I d e n t i fi c a t i o n
markings" section) to ensure that
the optimum dynamic perform-
ance 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.

crossed on the right,
- on the left-hand side, if the mark- ing on the ground has been
crossed on the left.
No warning is transmitted while the
direction indicator is active and for
approximately 20 seconds after the
direction indicator is switched off.
A warning may be transmitted if a
direction marking (e.g. arrow) or
n o n - s t a n d a r d m a r k i n g ( e . g . g r a f fi t i )
is crossed. Operating fault
In the event of a malfunction, the
service warning lamp comes on,
accompanied by an audible signal
and a message on the multifunction

The lane departure warning sys-
tem cannot, in any circumstances,
replace the need for vigilance and
responsibility on the part of the
driver. The detection may be impeded:
- if the sensors are dirty (mud,
snow...),
- if the markings on the ground are worn,
- if there is little contrast between the markings on the ground and
the road surface.

VISUAL AND AUDIBLE FRONT AND/OR REAR PARKING ASSISTANCE
System consisting of four proximity
sensors, installed in the front and/or
rear bumper.
It detects any obstacle (person, ve-
hicle, tree, barrier...) located behind
the vehicle, however, it will not be
able to detect obstacles located im-
mediately below the bumper.
An object, such as a stake, a road-
works cone or any other similar ob-
ject may be detected at the start of
the manoeuvre but may no longer
be detected when the vehicle moves
nearer to it. The parking assistance is
switched
off :
- when you exit reverse gear,
- when the speed is higher than 6 mph (10 km/h) in forward
gear,
- when the vehicle has been sta- tionary for more than three sec-
onds in forward gear.
The parking assistance system
cannot, in any circumstances, re-
place the need for vigilance and
responsibility on the part of the
driver.
The parking assistance is
switched
on :
- by engaging reverse gear,
- at a speed below 6 mph (10 km/h) in forward gear.
This is accompanied by an audible
signal and/or displaying of the vehi-
cle on the multifunction screen.
The proximity information is indicated
by:
- an audible signal which be- comes more rapid as the vehicle
approaches the obstacle,
- a diagram on the multifunction screen, with blocks which move
closer to the vehicle.
The obstacle is located in relation to
the emission of the audible signal by
the speakers; front or rear and right
or left.
When the distance between the ve-
hicle and the obstacle is less than
approximately thirty centimetres,
the audible signal becomes con-
tinuous and/or the "Danger" symbol
appears, depending on the multi-
function screen version.

In bad weather or in winter, ensure
that the sensors are not covered
with mud, ice or snow. When re-
verse gear is engaged, an audible
signal (long beep) indicates that
the sensors may be dirty.
When the vehicle is being driven
at a speed below approximately
6 mph (10 km/h), certain sourc-
es of noise (motorcycles, lorries,
pneumatic drills, ...) may trigger the
reversing audible signal.
Reactivation
Press button A again, the warn-
ing lamp switches off, the system
is reactivated.
Deactivation Operating fault
If an operating fault occurs, this warn-
ing lamp is displayed on the instrument
panel and/or a message appears on
