Air conditioning
To ensure that your system operates
correctly, it is recommended that you
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 preserve the sealing of the air
conditioning compressor, operate
the air conditioning at least once a
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
excessive, air the passenger com-
partment 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.

T h i s fi l t e r h a s t o b e c h a n g e d i n
accordance with the vehicle's ser-
vicing schedule (see "Maintenance
and Warranty Guide").
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 in the passenger com-
partment uses a number of sensors
(sunshine sensor, ambient tempera-
ture sensor...) that relieve you of the
need to make frequent adjustments
to the displayed temperature.
Take care not to obstruct the sun-
shine sensor, located on the dash-
board behind the instrument panel.

In the event of a malfunction with
the system, the "ECO OFF" switch
w a r n i n g l a m p fl a s h e s t h e n c o m e s
on continuously.
Have it checked by a CITROËN
dealer.
In the event of a fault in STOP mode,
the vehicle may stall. It is then nec-
essary to switch off the ignition and
start the engine again using the key. Maintenance
Operating fault
Before working under the
bonnet, deactivate the Stop
& Start system to avoid any
r i s k o f i n j u r y r e s u l t i n g f r o m a u t o -
matic operation of START mode.
This system requires a battery with
a s p e c i a l s p e c i fi c a t i o n a n d t e c h n o l o g y
(reference numbers available from
C I T R O Ë N d e a l e r s ) .
Fitting a battery not listed by
CITROËN introduces the risk of
malfunction of the system.
The Stop & Start system makes use of advanced technology.
Specialist knowledge is needed
for any work on the system, which can
only be assured by CITROËN dealers.

RUNNING OUT OF FUEL (DIESEL)
1.6 litre HDi engine
Detach the protective cover for
access to the priming pump. 2.0 litre HDi engine
Detach the protective cover for ac-
cess to the priming pump. Priming the fuel system
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.

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.

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

Oil level
Engine 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 manufactur-
er's recommendations.

Coolant level
Changing the coolant
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
1 5 m i n u t e s .
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
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
regulated by the fan. This can oper-
ate 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 al-
low the pressure to drop. When the
pressure 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. When working under the
bonnet, take care, as cer-
tain areas of the engine
may be extremely hot (risk
of burns).
Power steering fluid level T h e p o w e r s t e e r i n g fl u i d
level should be close to the
"MAX" mark. Unscrew the
cap, with the engine cold, to
check the level.

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 re-
quire any maintenance.
However, check that the
terminals are clean and
correctly tightened, partic-
ularly 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 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" section).

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 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 mes-
sage appears on the multifunction
screen, accompanied by an audi-
ble signal and lighting of the service
warning lamp.

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.

The gearbox does not re-
quire any maintenance (no
oil change).

control gearbox The gearbox does not re-
quire any maintenance (no
oil change).
Automatic gearbox The gearbox does not re-
quire any maintenance (no
oil change). Brake disc wear status
For information relating to
checking the brake disc
wear status, contact a
CITROËN dealer.
Electric parking brake
This system does not require any
routine servicing. However, in the
event of a problem, have the system
checked by a CITROËN dealer.
For more information, see "Driving -
Electric parking brake - § Operating
faults". Only use products recom-
mended by CITROËN or
products of equivalent qual-
i t y 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 of-
f e r s v e r y s p e c i fi c p r o d u c t s .
To avoid damaging the electrical
units, the use of a high pressure
washer in the engine compartment
is strictly prohibited .
