COMFORT
VENTILATION
System which creates and maintains
comfortable conditions in the vehicle's
passenger compartment. Air flow paths
The incoming air follows various routes
depending on the controls selected by
the driver:
- direct arrival in the passenger com-
partment (air intake),
- passage through a heating circuit (heating),
- passage through a cooling circuit (air conditioning).
The temperature control enables you to
obtain the level of comfort required by
mixing the air of the various circuits. The air distribution control enables you
to diffuse the air in the passenger com-
partment combining several air vents.
T h e a i r fl o w c o n t r o l e n a b l e s y o u t o
increase or reduce the speed of the
ventilation blower.
Air intake
The air circulating in the passenger com-
p a r t m e n t i s fi l t e r e d a n d o r i g i n a t e s e i t h e r
from the outside via the grille located at
the base of the windscreen or from the
inside in air recirculation mode. Control panel
The controls of this system are grouped
together on control panel
A on the cen-
tre console. Depending on the model,
the functions offered are:
- the level of comfort required,
- a i r fl o w ,
- air distribution,
- demisting and defrosting,
- manual or automatic air conditioning controls.
Air distribution
1. Windscreen demisting or defrosting
vents.
2. Front side window demisting or de-
frosting vents.
3. Side adjustable air vents.
4. Central adjustable air vents.
5. Air outlets to the front footwells.
6. Air outlets to the rear footwells.

choice from that offered by the system
by changing a setting. The other func-
tions will still be controlled automatically.
Pressing the "AUTO" button returns
the system to completely automatic
operation.
Press this button to switch
off the air conditioning. 6 . A i r d i s t r i b u t i o n a d j u s t m e n t

T u r n t h e a i r fl o w c o n t r o l t o t h e l e f t u n t i l
all of the indicator lamps switch off.
This action switches off the air condi-
tioning and the ventilation.
Temperature related comfort is no lon-
g e r g u a r a n t e e d b u t a s l i g h t fl o w o f a i r ,
due to the movement of the vehicle, can
still be felt.
T u r n t h e a i r fl o w d i a l t o t h e r i g h t o r
press the "AUTO" button to reacti-
vate the system with the values set
before it was switched off.
Press this button for recir-
culation of the interior air.
The indicator lamp on the
button comes on.
5. Air conditioning On/Off
Avoid prolonged operation in inte-
rior air recirculation mode or driving
for long periods with the system off
(risk of condensation and deterio-
ration of the air quality).
- the windscreen and side windows
(demisting or defrosting),
- the windscreen, the side windows and the vents,
- the windscreen, the side windows, the vents and the footwells,
- the vents and the footwells,
- the vents,
- the footwells,
- the windscreen, the side windows and the footwells.
T h e a i r fl o w i n d i c a t o r l a m p s , b e t w e e n
the two fans, come on progressively in
relation to the value requested.
As soon as possible, press this but-
ton again to permit the intake of out-
side air and prevent the formation
of condensation. The indicator lamp
on the button switches off.
For maximum cooling or heating
of the passenger compartment, it
is possible to exceed the minimum
value 14 or the maximum value 28.
Turn control 2 or 3 to the left
until "LO" is displayed or to the
right until "HI" is displayed. 9 . M o n o - z o n e / D u a l - z o n e
Press this button to equalise
the comfort value on the
passenger side with that
on the driver's side (mono
zone). The indicator lamp
on the button comes on.
Air recirculation enables the passenger
compartment to be isolated from exte-
rior odours and smoke.
Switching the system off could result in
discomfort (humidity, condensation).
Press this button again to return to
automatic operation of the air con-
ditioning. The indicator lamp on the
"A/C" button comes on.

CHECKS
CHECKING LEVELS Brake fluid level
Oil level The reading will only be correct
if the vehicle is on level ground
and the engine has been off for
more than 15 minutes.
The check is carried out either when the
ignition is switched on using the oil level
indicator on the instrument panel, or
using the dipstick. T h e b r a k e fl u i d l e v e l s h o u l d b e
close to the "MAX" mark. If it is
not, check the brake pad wear.
C h a n g i n g t h e fl u i d
Refer to the Maintenance and Warranty
Guide for details of the interval for this
operation.
Coolant level The coolant level should be
close to the "MAX" mark but
should never exceed it.
When the engine is warm, the
temperature of the coolant is regulated
by the fan. This can operate with the
ignition off.
O n v e h i c l e s w h i c h a r e fi t t e d w i t h a
p a r t i c l e e m i s s i o n fi l t e r , t h e f a n m a y
operate after the vehicle has been
s w i t c h e d o f f , e v e n i f t h e e n g i n e i s
cold.
In addition, as the cooling system is
pressurised, wait at least one hour after
switching off the engine before carrying
out any work. F l u i d s p e c i fi c a t i o n
For optimum cleaning and to avoid
f r e e z i n g , t h i s fl u i d m u s t n o t b e t o p p e d
up or replaced with water.
Engine oil change
Refer to the Maintenance and Warranty
Guide for details of the interval for this
operation.
In order to maintain the reliability of the
engine and emission control system,
the use of additives in the engine oil is
prohibited.
Oil grade
The oil must be suitable for your engine
and conform to the manufacturer's recom-
mendations. F l u i d s p e c i fi c a t i o n
T h e b r a k e fl u i d m u s t c o n f o r m t o t h e
manufacturer's recommendations and
meet the DOT4 standard.
F l u i d s p e c i fi c a t i o n
The coolant must conform to the manu-
facturer's recommendations.
Changing the coolant
The coolant does not have to be
changed.
Screenwash fluid level
Check all of these levels regularly and
top them up if necessary, unless other-
wise indicated.
I f a l e v e l d r o p s s i g n i fi c a n t l y , h a v e t h e
corresponding system checked by a
CITROËN dealer.
To avoid any risk of scalding, unscrew
the cap by two turns to allow the pres-
sure to drop. When the pressure has
dropped, remove the cap and top up
the level.
Top up the level when necessary.
Take care when carrying out checks under the bonnet as some parts of
the engine can be very hot (risk of
burns).

PRACTICAL INFORMATION
TOWING A TRAILER, A CARAVAN, ETC.
Your vehicle is primarily designed for
transporting people and luggage, but it
may also be used for towing a trailer. Driving advice
T h e m a x i m u m t o w i n g l o a d o n a l o n g
slope depends on the gradient and the
ambient temperature.
In all cases, pay attention to the coolant
temperature.
Side wind
Take into account the increased
sensitivity to side wind.
Cooling
Towing a trailer on a slope increases
the temperature of the coolant.
As the fan is electrically controlled, its
cooling capacity is not dependent on
the engine speed.
To lower the engine speed, reduce
your speed. Braking
Towing a trailer increases the braking
distance.
Tyres
Check the tyre pressures of the
towing vehicle and of the trailer,
observing the recommended pres-
sures.
Lighting
Check the electrical lighting and
signalling on the trailer.
The rear parking sensors will be de-
activated automatically if a genuine
CITROËN towbar is used.
If the warning lamp and the
STOP warning lamp come
on, stop the vehicle and
switch off the engine as
soon as possible.
Towbar suitable for the attachment of a
trailer or caravan with additional lighting
and signalling.
Distribution of loads
Distribute the load in the trailer so
that the heaviest items are as close

Air density decreases with altitude, thus
reducing engine performance. Above
1 0 0 0 m e t r e s , t h e m a x i m u m t o w i n g l o a d
must be reduced by 10 % and so on for
every 1 000 metres of altitude.
Refer to the "Technical Data" section for
details of the weights and towing loads
which apply to your vehicle.
Driving with a trailer subjects the towing
v e h i c l e t o m o r e s i g n i fi c a n t s t r e s s a n d i t s
driver must be particularly careful.
We recommend the use of genuine
CITROËN towbars and their har-
nesses that have been tested and
approved from the design stage
