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 exces-
sive, air 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.

Air circulation
A i r v e n t s o n t h e fl o o r u n d e r n e a t h t h e
front seats provide enhanced heat-
ing for the rear seat positions; take
care not to obstruct them.
Air vents
The air vents to the face 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
a number of sensors (sunlight sen-
sor, outside temperature sensor...)
that relieve you of the need to make
frequent adjustments outside the
displayed temperature.
Be careful not to obstruct the sun-
light sensor, located on the dash-
board behind the instrument panel.

RUNNING OUT OF FUEL (DIESEL)
HDi 138 engine
Detach the protective cover for access
to the priming pump. HDi 110 engine
Detach the protective cover for access
to the priming pump. Priming the fuel circuit
In the event of running out of fuel:
a f t e r fi l l i n g ( m i n i m u m 5 l i t r e s ) ,
squeeze the manual priming
pump repeatedly, until some re-
sistance is felt,
then operate the starter, gently
pressing the accelerator until the
engine starts.
I f t h e e n g i n e f a i l s t o s t a r t a t t h e fi r s t
attempt, wait 15 seconds before
trying again.
If the engine fails to start after a few
attempts, repeat the procedure from
the beginning. When the engine is
idling, accelerate gently to complete
the purge of the circuit.
HDi engines are of a highly
technical nature.

CHECKING LEVELS
Check all of these levels regularly
and top them up if necessary, unless
otherwise indicated.

CITROËN dealer.
Take care when working under the
bonnet, as some parts of the engine
can be extremely hot (risk of burns).
Oil level
Oil change
Refer to the Maintenance and
Warranty Guide for details of the in-
terval for this operation. O i l s p e c i fi c a t i o n The oil must correspond to your en-gine and conform to the manufacturer's
recommendations.
Brake fluid level

Warranty Guide for details of the in-
terval for this operation.

Coolant level
Coolant change
The coolant does not have to be
changed.
F l u i d s p e c i fi c a t i o n
The coolant must conform to the
manufacturer's recommendations.
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.
Check this level also between each
scheduled service and before long
journeys. T h e b r a k e fl u i d l e v e l s h o u l d
be close to the "MAX" mark.
If it is not, check the brake
pad wear.
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 regu-
lated by the fan. This can operate with
the ignition off.

gine 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.
To avoid any risk of scalding, un-
screw the cap by two turns to allow
the pressure to drop. When the pres-
sure has dropped, remove the cap
and top up the level.
In order to maintain the re-
liability of the engine and
emission control system,
the use of additives in the engine
oil is prohibited.

CHECKS
Unless otherwise indicated, check
these components in accordance
with the Maintenance and Warranty
Guide and according to your engine.
Otherwise, have them checked by a
CITROËN dealer.
Battery The battery does not require
any maintenance.
However, check that the
terminals are clean and
correctly tightened, par-
ticularly in summer 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 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" paragraph).

tive contribution to the preservation
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 occa-
sionally notice water vapour being
emitted from the exhaust when ac-
celerating. This is of no consequence
to the running of the vehicle or to the
environment.
If there is risk of clogging, a mes-
sage appears on the multifunction
screen, accompanied by an audi-
ble signal and lighting of the service
warning lamp.
This alert tells you that the particle

Brake pads Brake wear depends on
the style of driving, par-
ticularly in the case of ve-
hicles 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
d r o p i n t h e b r a k e fl u i d l e v e l i n d i c a t e s
that the brake pads are worn.
Manual gearbox
The gearbox does not re-
quire any maintenance (no
oil change).
6 - s p e e d e l e c t r o n i c g e a r
control gearbox
The gearbox does not require any
maintenance (no oil change).
Automatic gearbox
The gearbox does not require any
maintenance (no oil change). Brake disc wear
For information relating to
checking the brake disc
wear, contact a CITROËN
dealer.
Parking brake
If a loss of effectiveness of this sys-
tem is noticed, the parking brake
must be checked, even between two
services.
This system must be checked by a
CITROËN dealer. Only use products recom-
mended by CITROËN or
products of equivalent quality
a n d s p e c i fi c a t i o n s .
In order to optimise the operation
of units as important as the braking
system, CITROËN selects and offers

To avoid damaging the electrical
units, the use of a high pressure
washer in the engine compartment is
strictly prohibited .
