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 valfor this operation.


Fluid specifi cation

The brake fluid must conform to themanufacturer's recommendations and meet
the DOT4 s t a n d a r d . Th
e brake fluid level should be closeto the "MA X" mark. If it is not, check
the brake pad wear.
The readin
g 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 theignition is switched on using the oil level
indicator in the instrument panel, or usingthe 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,
to check 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.

the reservoir to read the level in the
transparent section. )Top up if necessary. )Refit the filler cap to the reser voir and close the bonnet.

Specifi cation of the fl uid

To ensure optimum cleaning and to avoid
freezing, the fluid should never be topped up or
replaced by plain water. Accordin
g to your version of instrument panel,
the additive reser voir low level is indicated by:
-fixed illumination of the particle emissions filter warning lamp, accompanied by an audible signal anda message that the particle emissionsfilter additive level is too low,
or

- fix
ed illumination of the servicewarning lamp, accompanied by
an au

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.
