Checks

























Checking levels
Check all of these levels regularly and top them up if necessary, unless other wise indicated.
If a level drops si
gnificantly, have the corresponding system checked by a CITROËN dealer or a qualified workshop.


Oil level
Engine oil change
Refer to the servicing booklet for the inter val for
this operation.
In order to maintain the reliabilit
y 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 engineand conform to the manufacturer'srecommendations.



Brake fluid level


Changing the fl uid

Refer to the servicing booklet for the inter val for
this operation.

Fluid specifi cation

The brake fluid must conform to themanufacturer's recommendations and meet theDOT4 standard.
Th
e brake fluid level should be closeto the "MA X" mark. If it is not, check
the brake pad wear.
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 levelindicator in the instrument panel, or using the dipstick.
When working under the bonnet, take care, as cer tain areas of the engine may be extremely hot (risk of burns).
It is normal to top up the oil level
between two services. CITROËN recommends that you check the oillevel, and top up if necessary, every 3 000 miles (5 000 kilometres).

Changing the coolant
The coolant does not have to be changed.


Coolant specifi cation

The coolant must conform to the
manufacturer's recommendations.

Coolant level
The coolant level should be close
to the "MA X" 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 fitted with a par ticle
emission filter, the fan may operate after
the vehicle has been switched off, even if
the en
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 a v o i d a ny risk of scalding, unscrew the cap by two turns to allow the pressure to drop. When the pressure has dropped, remove the cap and top up the level.
Power steering fluid level
The power steering fluid level should
be close to the "MA X" mark. Unscrew
the cap, with the engine cold, tocheck the level. To check the level or top up the
fluid on vehicle fitted with headlamp
washers
, immobilise the vehicle and switch of the engine.

Checks


Air filter and passenger compartment filter


Oil filter
Unless other wise indicated, check these components in accordance with the ser vicing booklet and according to your engine.
Other wise, have them checked b
y a CITROËN dealer or a qualified workshop.
The batter
y does not require anymaintenance.
However, check that the terminals
are clean and correctl
y tightened, particularly in summer and winter.
When carrying out work on the battery, refer
to the "Practical information" section for
details of the precautions to be taken before
disconnecting the battery and following itsreconnection. Re
fer to the ser vicing booklet for
details of the replacement inter vals
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" section). y A clogged passenger compar tment filter mayhave an adverse effect on the performance
of the air conditioning system and generate undesirable odours.
Re
place the oil filter each timethe engine oil is changed.
Refer to the ser vicing booklet for
details of the replacement inter val for
this component.
The presence of this label, in particular with the Stop & Star t system, indicates the use of a specific 12 V lead-acid battery with special technology and specification. The involvement of a CITROËN dealer or a qualified workshop is essential when replacingor disconnecting the battery.

Electric parking brake
This system does not require anyroutine servicing. However, in the event of a problem, have the system checked by a CITROËN dealer or aqualified workshop.
For more information, see "Driving - Electric
parking brake - § Operating faults".

















Only use products recommended by CITROËN or products of equivalent quality and specification. In order to optimise the operationof units as impor tant as the braking system, CITROËN selects and offersvery specific products.
To a v o i d d a m aging the electrical units,the use of a high pressure washer in the engine compar tment is strictly
prohibited.Brake disc wear

For information on checking brake
disc wear, contact a CITROËN dealer
or a qualified workshop.


Manual parking brake
If a loss of effectiveness of this
system is noticed, the parking brake must be checked, even betweentwo services.
Checking this system must be done by aCITROËN dealer or a qualified workshop.
Brake pads
Brake wear depends on the styleof driving, par ticularly in the case of vehicles used in town, over shor t
distances. It may be necessary to have the condition of the brakes checked,even between vehicle services. Unless there is a leak in the system, a drop in
the brake fluid level indicates that the brake pads are worn.

)Switch on the compressor by movingthe switch Bto position "I" until the tyre pressure reaches 2.0 bars.
The sealant is injected into the tyre under
pressure; do not disconnect the pipe from
the valve during this operation (risk of
splashing).
)Remove the kit and screw the cap back on
the white pipe.
Take care to avoid staining your vehicle
with traces o
f fluid. Keep the kit to hand.
)Drive immediately for approximately three miles (five kilometres), at reduced speed (between 15 and 35 mph (20 and 60 km/h)),
to plug the puncture.)Stop to check the repair and the tyre pressure using the kit.
Do not star t the compressor beforeconnecting the white pipe to the tyrevalve: the sealant product would beexpelled through the pipe.
Tyre under-infl ation detection
If the vehicle is fitted with tyre under-inflation detection, the under-inflationwarning lamp will remain on after the wheel has been repaired until the system is reinitialised by a CITROËN dealer or a qualified workshop.
If after around 5 to 7 minutes thepressure is not attained, this indicates that the tyre is not repairable; contact a CITROËN dealer or a qualified workshop for assistance.
