Checking levels

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


Oil level


Engine oil change

Refer to the ser vicing booklet for the inter val 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
recommendations.



Brake fluid level


Changing the fl uid

Refer to the Maintenance and Warranty Guide
for the inter val for this operation.


Fluid specifi cation

The brake fluid must conform to the
manufacturer's recommendations and meet
the DOT4 standard.
The brake fluid level should be close
to 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 level indicator 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 ser vices. CITROËN
recommends that you check the oil
level, 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 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 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.

Checks


Battery

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 by a CITROËN dealer or a qualified workshop.
The battery does not require any
maintenance.
However, check that the terminals
are clean and correctly 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 its
reconnection. Refer to the servicing 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).
A clogged passenger compar tment filter may
have an adverse effect on the per formance
of the air conditioning system and generate
undesirable odours.
Replace the oil filter each time
the engine oil is changed.
Refer to the servicing 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, for which the
involvement of a CITROËN dealer or a qualified
workshop is required when replacing or
disconnecting the battery.
Failure to obser ve this recommendation may
shor ten the life of the battery.

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 or a
qualified 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 operation
of units as impor tant as the braking
system, CITROËN selects and offers
very specific products.
To avoid damaging 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 between
two ser vices.
Checking this system must be done by a
CITROËN dealer or a qualified workshop.
















Brake pads

Brake wear depends on the style
of 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 ser vices.
Unless there is a leak in the system, a drop in
the brake fluid level indicates that the brake
pads are worn.
