CHECKING LEVELS
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 or a qualifi ed work-
shop.
When working under the bonnet,
take care, as certain areas of the
engine may be extremely hot (risk
of burns).
The reading will only be correct if
the vehicle is on level ground and
the engine has been off for more
than 30 minutes.
The check is carried out either when the
ignition is switched on using the oil level
indicator in the instrument panel, or using
the dipstick.
It is normal to top up the oil level between
two services. CITROËN recommends that
you check the oil level, and top up if neces-
sary, every 3 000 miles (5 000 kilometres).
Oil level
Engine oil change
Refer to the servicing booklet for 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 specifi cation
The oil must correspond to your engine
and conform to the manufacturer's rec-
ommendations.
Brake fluid level
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 servicing booklet for the
interval for this operation.
Fluid specifi cation
The brake fl uid must conform to the
manufacturer's recommendations and
meet the DOT4 standard.
Power steering fluid level
The power steering fl uid level
should be close to the "MAX"
mark. Unscrew the cap, with
the engine cold, to check the
level.
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 ig-
nition off.
On vehicles which are fi tted with a par-
ticle emission fi lter, the fan may oper-
ate 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.
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.
Changing the coolant
The coolant does not have to be
changed.
Coolant specifi cation
The coolant must conform to the manu-
facturer's recommendations.

Used products
Avoid prolonged contact of used
oil or fl uids with the skin.
Most of these fl uids are harmful
to health or indeed very corro-
sive.
Do not discard used oil or fl uids
into sewers or onto the ground.
Take used oil to a CITROËN
dealer or a qualifi ed workshop
(France) or to an authorised
waste disposal site.
Additive level (Diesel with
particle emissions filter)
According to your version of instrument
panel, the additive reservoir low level is
indicated by:
Topping up
The reservoir must be topped up with-
out delay by a CITROËN dealer or a
qualifi ed workshop.
- fi xed illumination of the par-
ticle emissions fi lter warning
lamp, accompanied by an au-
dible signal and a message
that the particle emissions fi l-
ter additive level is too low,
- fi xed illumination of the
service warning lamp, ac-
companied by an audible
signal and a message that
the particle emissions fi lter additive level is too low. or
Screenwash/headlamp wash
level
Specifi cation of the fl uid
To ensure optimum cleaning and to
avoid freezing, the fl uid should never be
topped up or replaced by plain water.
To check the level or top up the
fl uid on vehicle fi tted with head-
lamp washers, immobilise the
vehicle and switch of the engine.
)
Open the bonnet and secure it with
the stay.
)
Open the screenwash reservoir fi ller
cap.
)
Take and pinch the level gauge to
block its breather.
)
Remove the gauge completely from
the reservoir to read the level in the
transparent section.
)
Top up if necessary.
)
Refi t the fi ller cap to the reservoir
and close the bonnet.

Amber coloured bulbs, such as
the direction indicators, must be
replaced with bulbs of identical
specifi cations and colour.
When refi tting, close the protec-
tive cover carefully to preserve
the sealing of the headlamp.
Changing direction indicator bulbs
Model with halogen headlamps
Rapid fl ashing of the direction
indicator warning lamp (right
or left) indicates the failure of a
bulb on that side.
Access to bulbs
)
Remove the air defl ector by unclip-
ping each of its three attachment
points.
)
Unclip the bonnet release cable at
its two fi xings.
)
Move the cable down.
After changing the failed bulb, remember
to put everything back in place (cable and
air defl ector). Depending on the engine and only on
the left hand side, you must fi rst carry
out the following operations for access
to the protective covers on the bulbs.
)
Turn the bulb holder a quarter of a
turn and extract it.
)
Pull out the bulb and change it.
To reassemble, carry out these opera-
tions in reverse order.
Model with Xenon headlamps
)
Remove the protective cover by
pulling on its tongue.
)
Disconnect the electrical connector.
)
Separate the springs to release the
bulb.
)
Pull the bulb out and replace it.

BATTERY
The battery is located under the bonnet.
To gain access to it:
)
open the bonnet using the interior re-
lease lever, then the exterior safety
catch,
)
secure the bonnet stay,
)
remove the plastic cover to gain ac-
cess to the two terminals,
)
unclip the fuse box to remove the
battery, if necessary.
Access to the battery
Disconnecting the cables
Do not force the tab as locking
will not be possible if the clip is
not positioned correctly; start the
procedure again.
The presence of this label, in
particular with the Stop & Start
system, indicates the use of a
12 V lead-acid battery with spe-
cial technology and specifi cation;
the involvement of a CITROËN
dealer or a qualifi ed workshop is
essential when replacing or dis-
connecting the battery.
Failure to observe this recom-
mendation may cause premature
wear of the battery. Procedure for charging your battery
when it is fl at or for starting the engine
using another battery.
After refi tting the battery, the
Stop & Start system will only be
active after a continuous period
of immobilisation of the vehicle,
a period which depends on the
climatic conditions and the state
of charge of the battery (up to
about 8 hours).
)
Position the open clip 1
of the cable
on the positive terminal (+) of the
battery.
)
Press vertically on the clip 1
to position
it correctly against the battery.
)
Lock the clip by lowering the tab 2
.
)
Raise the locking tab fully.

under the bonnet.
This number is engraved on the body-
work near the engine mounting.

the dashboard.
This number is indicated on a self-
adhesive label which is visible through
the windscreen.
D. Tyre/paint label.
This label is affi xed to the driver's front
pillar.
The tyre pressures must be
checked when the tyres are cold,
at least once a month.
Low tyre pressures increase fuel
consumption.
C. Manufacturer's label.
The VIN is indicated on a self-destroying
label affi xed to the driver's centre pillar. It bears the following information:
- the tyre pressures, for unladen and
laden conditions,
- the wheel rim and tyre sizes,
- the brands of tyre recommended by
the manufacturer,
- the spare tyre infl ation pressure,
