COMFORT
The air conditioning system does
not contain chlorine and does not
present any danger to the ozone
layer.
In order for these systems to be fully effective, follow the g uidelines on opera-
tion and maintenance below:

 If the interior temperature remains very high after the vehicle has been
parked in the sun for a considerable time, fi rst ventilate the passenger
compartment for a few minutes.
Place the air fl ow control at a suffi cient level t o provide an adequate renewal
of air in the passenger compartment.

 To obtain an even air distribution, take care not to obst ruct the exterior air
intake grilles located at the base of the windscreen, the n ozzles, the vents
and the air outlets, as well as the air extractor located in the passenger
compartment on both sides of the rear shelf.

 Do not cover the sunshine sensor, located on the dashboard (behind the
instrument panel); this is used for regulation of t he air conditioning system.

 Operate the air conditioning system for 5 to 10 minutes, on ce or twice a
month to keep it in good working order.

 Ensure that the passenger compartment fi lter is in good condit ion and
have the fi lter elements replaced regularly (refer to the "Checks" section).
We recommend the use of a combined passenger compartment fi lter.
Thanks to its second special active fi lter, it contributes to t he purifi cation
of the air breathed by the occupants and the cleanliness of the passen-
ger compartment (reduction of allergic symptoms, bad odours and grea sy
deposits).

 To ensure correct operation of the air conditioning system, you are also
advised to have it checked regularly.

 If the system does not produce cold air, do not use it and contact a
CITROËN dealer.
When towing the maximum load on a steep gradient in high temperatures,
switching off the air conditioning saves engine power and so improves towing
capacity.
The condensation created by the air conditioning results in a discharge of
water under the vehicle which is perfectly normal.

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 us-
ing the dipstick. The brake fl uid level should be
close to the "MAX" mark. If it is
not, check the brake pad wear.
Changing the fl uid
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.

On vehicles which are fi tted with a
particle emission fi lter, the fan may
operate after the vehicle has been
switched off, even if the engine is
cold.
In addition, as the cooling system is
pressurised, wait at least one hour after
switching off the engine before carrying
out any work. Fluid specifi cation
For optimum cleaning and to avoid
freezing, this fl uid must not be topped
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. Fluid specifi cation
The brake fl uid must conform to the
manufacturer's recommendations and
meet the DOT4 standard.
Fluid specifi cation
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.
If a level drops signifi cantly, have the
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 neces-
sary.
Take care when carrying out checks under the bonnet as some parts of
the engine can be very hot (risk of
burns).

CHECKS
Avoid prolonged contact of used oil
or fl uids with the skin.
Most of these fl uids are harmful to
health or indeed very corrosive.
Do not discard used oil or fl uids
into sewers or onto the ground.
Take used oil to a CITROËN dealer
(France) or an authorised waste
disposal site.
Diesel additive level (Diesel
engine with particle emission
filter)
A low additive level is indicated by light-
ing of the service warning lamp, accom-
panied by an audible warning and a
message on the multifunction screen.

CHECKS
Battery
The battery does not require
any maintenance.
However, check that the ter-
minals are clean and correctly
tightened, particularly in sum-
mer and winter.
When carrying out work on the battery,
refer to the "Practical information" sec-
tion for details of the precautions to be
taken before disconnecting the battery
and following its reconnection.
Air filter and passenger compartment filter
Refer to the Maintenance and
Warranty Guide for details of
the replacement intervals for
these components.
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" paragraph).
A clogged passenger compartment fi lter
may have an adverse effect on the per-
formance of the air conditioning system
and generate undesirable odours. Particle emission filter (Diesel)
It is imperative that the maintenance of
the particle emission fi lter is carried out
by a CITROËN dealer.
Oil filter
Replace the oil fi lter each time
the engine oil is changed.
Refer to the Maintenance and
Warranty Guide for details of
the replacement interval for
this component.
Following prolonged operation of
the vehicle at very low speed or at
idle, you may, in exceptional cir-
cumstances, notice the emission
of water vapour at the exhaust on
acceleration. This does not affect
the behaviour of the vehicle or the
environment.
Topping up
This additive must be topped up by a
CITROËN dealer without delay.
Unless otherwise indicated, check
these components in accordance with
the Maintenance and Waranty Guide
and according to your engine.
Otherwise, have them checked by a
CITROËN dealer.

CHECKS Only use products recommended
by CITROËN or products of equiva-
lent quality and specifi cations.
In order to optimise the operation
of units as important as the braking
system, CITROËN selects and of-
fers very specifi c products.
To avoid damaging the electrical
units, the use of a high pressure
washer in the engine compartment
is strictly prohibited .
Brake disc wear
Brake pads Parking brake Brake wear depends on the
style of driving, particularly in
the case of vehicles used in
town, over short distances. It
may be necessary to have the
condition of the brakes checked, even
between vehicle services.
Unless there is a leak in the circuit, a
drop in the brake fl uid level indicates
that the brake pads are worn. For information relating to
checking the brake disc wear,
contact a CITROËN dealer.
If a loss of effectiveness of this
system is noticed, the parking
brake must be checked, even
between two services.
This system must be checked
by a CITROËN dealer.
Manual gearbox
The gearbox does not re-
quire any maintenance (no oil
change).
Refer to the Maintenance and
Warranty Guide for the details
of the level checking interval for this
component.
