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).

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.
