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).

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.
