COMFORT
VENTILATION
Recommendations for use
If the interior temperature re-
mains very high after a pro-
longed period parked in the sun, fi rst
ventilate the passenger compartment
for a few minutes.
For an even air distribution, make
sure that you do not block the out-
side air inlet grille, the vents, the air
passages and the air outlets to the
footwells.
Ensure that the passenger compart-
ment fi lter, located below the wind-
screen, in the engine compartment,
is in good condition. Have the fi lter
elements replaced regularly. If you
drive in dusty conditions, change
them twice as often.
Operate the air conditioning system
for 5 to 10 minutes, once or twice a
month, to keep it in perfect working
order.
In order to ensure that your air condi-
tioning system continues to operate
correctly, you are advised to have it
checked regularly.
The condensation created by the air
conditioning results in a fl ow of water
under the vehicle when stationary
which is perfectly normal.
If the system does not produce
cold air, do not use it and contact a
CITROËN dealer or a qualifi ed work-
shop.

3. Side vents.

4. Diffusion grille.

5. Air outlets to the footwells.

1. Windscreen demisting/defrosting
vent.

2. Side window demisting/
defrosting vents.
The air conditioning system
does not contain chlorine
and does not present any
danger to the ozone layer.

SAFETY
When this warning lamp
comes on, it indicates that
there is a fault with the ABS,
which could cause a loss of
control of the vehicle when
braking.
Contact a CITROËN dealer or a
qualifi ed workshop.
When these warn-
ing lamps come on
simultaneously, it
indicates that there
is a fault with the braking system or
that the parking brake has not been
released fully, which can cause a
loss of control of the vehicle when
braking.

You must stop as soon as it is safe
to do so.
Contact a CITROËN dealer or a
qualifi ed workshop.
Normal operation of the ABS
may make itself felt by slight
vibrations of the brake pedal.

In emergency braking,
press very fi rmly without
releasing the pressure.
ANTI-SLIP REGULATION (ASR) AND ELECTRONIC STABILITY PROGRAMME (ESP)
Operating check
Operation of the ASR and ESP
systems
When one of these two sys-
tems is operating, this warning
lamp comes on.
If a fault occurs with the
systems, this warning lamp
comes on. The ASR/ESP systems offer
exceptional safety during nor-
mal driving, but this should not encourage the driver to take
extra risks or drive at high speed.
Correct operation of these systems
depends on observation of the manu-
facturer's recommendations regarding
the wheels (tyres and rims), the brak-
ing components and the electronic
components as well as the repair pro-
cedures use by a CITROËN dealer or
qualifi ed workshop.
After an impact, have these systems
checked by a CITROËN dealer or a
qualifi ed workshop.
Contact a CITROËN dealer or a
qualifi ed workshop to have the sys-
tems checked.
These systems are linked and sup-
plement the ABS.
The ASR system optimises drive to
prevent the wheels skidding, by act-
ing on the brakes of the driving wheels and on the engine. It also allows the
directional stability of the vehicle to
be improved on acceleration.
If there is a variation between the tra-
jectory followed by the vehicle and
that required by the driver, the ESP
system automatically acts on the
brake of one or more wheels and on
the engine to put the vehicle back on
course, within the limits of the laws
of physics.

CHECKS
CHECKING THE LEVELS
There are two marks
on the dipstick:

A = maximum
If you fi ll past this
mark, contact a
CITROËN dealer or a
qualifi ed workshop.

B = minimum
Never allow the level to
fall below this mark.
Dipstick
Oil change
According to the information given in
the servicing booklet. Changing the brake fluid
The brake fl uid must be changed at
the intervals stated, according to the
manufacturer's servicing schedule.
Use fl uids recommended by the
manufacturer, which fulfi l DOT4
standards.
Windscreen wash level
For best quality cleaning and for your
safety, we would advise that you
use products recommended by your
manufacturer.
Contact a CITROËN dealer or a
qualifi ed workshop.
Oil viscosity grade
In all cases, the oil selected must meet
the manufacturer's requirements. Cooling system
Used oil
Avoid prolonged contact of used oil
with the skin.
Brake fl uid is harmful to health and
very corrosive.
To maintain the reliability of
engines and emission control systems, the use of additives
in engine oil is prohibited. Slacken the cap by 1/4 of a
turn to release the pressure
to prevent any risk of
scalding. When the pressure
has dropped, remove the cap and
top up the level. Only use the fl uid recom-
mended by the manufacturer.
Otherwise, you risk seriously
damaging your engine.
Do not dispose of used oil,
brake fl uid or coolant into
drains or into the ground.
Empty the used oil into the
containers provided for this
purpose in the CITROËN dealer
network or at a qualifi ed workshop
(France) or at an authorised waste
disposal site.
Oil level
Check the level regularly and top up
between changes. The maximum oil
consumption is 0.5 litre per 600 miles
(1 000 km).
Check the level with the vehicle level,
engine cold, using the dipstick.
When the engine is warm, the
temperature of the coolant is
controlled by the engine fan. As this
fan can operate with the ignition key
removed and because the cooling
system is pressurised, wait for at
least one hour after the engine has
stopped before carrying out any
work.
