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.

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.
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 sunshine sensor located on the
dashboard behind the instrument
panel.
Be careful not to obstruct it.

Displays on the instrument panel
- The selector position is displayed in the instrument panel, on the left
on multifunction screens A and C
and on the right on the NaviDrive
multifunction screen.
- A back-lit position grille associ- ated with the selector shows the
position selected. Moving off
When the ignition is on, lighting of
the service warning lamp, accom-
panied by an audible signal and
the message "Gearbox faulty" in-
dicates a malfunction.
Consult a CITROËN dealer.
For safety:
Position N can only be disen-
gaged if you are pressing the
brake pedal.
If the gearbox is in position N
but the selector position is differ-
ent, reposition the selector on N
in order to be able to start.
To start the engine, the selector
must be in position N .
P r e s s fi r m l y o n t h e b r a k e p e d a l .
Operate the starter.
When the engine is running,
place the selector on R , A or M
as desired.
Check, in the instrument panel,
the position engaged.
Release the brake pedal and
accelerate.
If the selector is not in position N ,
and/or if the brake pedal is not
pressed, the corresponding warning
lamp(s) are displayed and a mes-
sage informs you that at least one of
these two conditions is not met.
In this case, the engine will not start,
recommence the above procedure.
Engaging reverse gear
To engage reverse gear, move the
selector to R .
Only attempt to select reverse gear
when the vehicle is stationary.
If the vehicle is moving rapidly, if an in-
advertent attempt to engage reverse
gear is made, the warning lamp N will
fl a s h a n d y o u r v e h i c l e w i l l g o a u t o -
matically into neutral. To re-engage a
gear, you have only to reposition the
selector on A , M or R .

Override of the programmed
speed
The accelerator pedal is equipped
with an end-of-travel switch. If you
action this switch by pressing the
pedal hard down, you can exceed
the memorised maximum speed at
any time.
During the time the speed is be-
ing exceeded, the displayed speed
fl a s h e s .
You have only to release the ac-
celerator pedal to return below the
maximum speed and render the
function active again.
If during the operation of the speed
limiter, the system is unable to keep
within the maximum speed (for ex-
ample on a steep descent or under
heavy acceleration) then the speed
fl a s h e s . A d a p t y o u r s p e e d a s n e c e s -
sary.
The function will re-engage when
your speed returns below the de-
sired maximum speed. Return to normal driving
By moving the control 1 from po-
sition "LIM" to position 0 .
By the engine stopping.
The speed previously chosen is still
memorised.
Operating fault
If there is a speed limiter malfunc-
tion, a message will display accom-
panied by an audible signal and
lighting of the service warning lamp.
Have it checked by a CITROËN
dealer.
On a steep downhill gradient or on
sharp acceleration, the speed limiter
will not be able to prevent the vehi-
cle from exceeding the programmed
speed.
U s e o f fl o o r m a t s t h a t a r e n o t a p -
proved by CITROËN may hinder
access to the accelerator pedal and
thus interfere with the functioning of
the speed limiter.
To avoid any risk of interfering with
the pedals:
- c h e c k t h a t t h e fl o o r m a t i s c o r - rectly positioned,
- n e v e r u s e m o r e t h a n o n e fl o o r mat.

Deactivation
Either by pressing on the brake
pedal or on the clutch pedal.
Or by pressing button 3 .
Or if either the ESP or the ASR
system is active.
The cruise control is not active if the
gear lever is in neutral.
These actions cause the information
"OFF" to appear on the instrument
panel screen.
These actions do not cancel the
cruise speed which remains dis-
played in the instrument panel.
Reactivation
By recall of the memorised
speed
After a disengagement, press on button 3 . Your vehicle automati-
cally returns to the memorised
cruise speed which is displayed
in zone A .
If the memorised cruise speed is higher than the current speed,
the vehicle will accelerate to
reach the former.
By selection of the current
speed
Press on button 2 or 4 once the
desired speed has been reached.
The information "OFF" will then
disappear from the instrument
panel display. Overriding the programmed
speed
During the operation of cruise con-
trol, it is always possible to use the
accelerator to go faster than the
cruise speed (for example to over-
take another vehicle). The speed
displayed in zone
A fl a s h e s .
You have only to release the accel-
erator pedal to return to the cruise
speed.
Return to normal driving
By an action on the control 1 from
position "REG" to position 0 .
By the engine stopping.
The cruise speed previously chosen is no longer memorised. Operating fault
If there is a malfunction, a mes-
sage will display accompanied by
an audible signal and lighting of the
service warning lamp.
Have it checked by a CITROËN
dealer.
If during the operation of cruise
control, the system is unable to
keep within the memorised speed
(for example on a steep descent),
t h e n t h e s p e e d fl a s h e s . A d a p t y o u r
speed as necessary. Cruise control should only be used
when the driving conditions allow
you to drive at a constant speed.
D o n o t u s e i t i n h e a v y t r a f fi c , o r o n
dangerous or slippery roads.
The driver must remain attentive
and in full control of his vehicle.
You are recommended to keep your
feet within range of the pedals.
To avoid any risk of interfering with
the pedals:
- c h e c k t h a t t h e fl o o r m a t i s c o r -
rectly positioned,
- n e v e r u s e m o r e t h a n o n e fl o o r mat.

CHECKS
Unless otherwise indicated, check
these components in accordance
with the Warranty and Maintenance
Record and according to your en-
gine.
Otherwise, have them checked by a
CITROËN dealer.
Battery The battery does not re-
quire any maintenance.
However, check that the
terminals are clean and
correctly tightened, particu-
larly in summer and winter.
When carrying out work on the bat-
tery, refer to the "Practical infor-
mation" section for details of the
precautions to be taken before dis-
connecting the battery and following
its reconnection.
Air filter and passenger compartment filter
Refer to the Warranty and
Maintenance Record for
details of the replacement
intervals for these compo-
nents.
Depending on the environment (e.g.
dusty atmosphere) and the use of
the vehicle (e.g. city driving), replace
them twice as often if necessary
(refer to the "Engines" section).

of air quality by the retaining of the
unburnt pollutant particles. Black
exhaust fumes are thus no longer
emitted.
After prolonged idling or driving at very
low speeds, you may occasionally no-
tice water vapour being emitted from
the exhaust when accelerating. This is
of no consequence to the running of
the vehicle or to the environment.
If there is risk of clogging, a message
appears on the multifunction screen,
accompanied by an audible signal
and lighting of the service warning
lamp.
