CHECKING LEVELS
Check all of these levels regularly and
top them up if necessary, unless other-
wise indicated.
If a level drops signifi cantly, have the corre-
sponding system checked by a CITROËN
dealer or a qualifi ed workshop.

When working under the bon-
net, take care, as certain areas
of the engine may be extremely
hot (risk of burns).

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 igni-
tion is switched on using the oil level indicator
in the instrument panel, or using the dipstick.

Oil level


Engine oil change
Refer to the Maintenance and Warranty
Guide for the interval 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 rec-
ommendations.



Brake fluid level

The brake fl uid level should be
close to the "MAX" mark. If it is
not, check the brake pad wear.

Changing the fl uid
Refer to the Maintenance and Warranty
Guide for the interval for this operation.

Fluid specifi cation
The brake fl uid must conform to the
manufacturer's recommendations and
meet the DOT4 standard.



Power steering fluid level

The power steering fl uid level
should be close to the "MAX"
mark. Unscrew the cap, with the
engine cold, to check the level.
Coolant level

The coolant level should be
close to the "MAX" 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 igni-
tion off.

On vehicles which are fi tted with a par-
ticle emission fi lter, 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 pres-
sure to drop. When the pressure has
dropped, remove the cap and top up
the level.

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

Coolant specifi cation
The coolant must conform to the manu-
facturer's recommendations.

Battery

The battery does not require
any maintenance.

However, check that the ter-
minals are clean and correctly
tightened, particularly in sum-
mer and winter.
When carrying out work on the battery,
refer to the "Practical information" sec-
tion for details of the precautions to be
taken before disconnecting the battery
and following its reconnection.

Particle emission filter (Diesel)

According to your version of instrument
panel, the start of saturation of the par-
ticle emissions fi lter is indicated by:


- fi xed illumination of the par-
ticle emissions fi lter warning
lamp, accompanied by an au-
dible signal and a message
that there is a risk of blockage
of the particle emissions fi lter,






The presence of this label, in particular
with the Stop & Start system, indicates
the use of a specifi c 12 V lead-acid bat-
tery with special technology and speci-
fi cation, for which the involvement of a
CITROËN dealer or a qualifi ed work-
shop is required when replacing or dis-
connecting the battery.
Failure to observe this recommendation
may shorten the life of the battery.

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 compartment fi l-
ter may have an adverse effect on the
performance of the air conditioning sys-
tem and generate undesirable odours.
As soon as the traffi c conditions per-
mit, regenerate the fi lter by driving at a
speed of at least 40 mph (60 km/h) until
the warning lamp goes off.
If the warning lamp stays on, refer to
the "Additive level" section.
Following prolonged operation
of the vehicle at very low speed
or at idle, you may, in excep-
tional circumstances, notice the
emission of water vapour at the
exhaust on acceleration. This
does not affect the behaviour of
the vehicle or the environment. or

Brake pads

Brake disc wear

If a loss of effectiveness of this
system is noticed, the parking
brake must be checked, even
between two services.
Checking this system must be
done by a CITROËN dealer or a quali-
fi ed workshop.

















Only use products recommended
by CITROËN or products of equiv-
alent quality and specifi cation.

In order to optimise the opera-
tion of units as important as
the braking system, CITROËN
selects and offers very specifi c
products.
To avoid damaging the electrical
units, the use of a high pressure
washer in the engine compart-
ment is strictly prohibited
.



Manual parking brake

For information on checking
brake disc wear, contact a
CITROËN dealer or a qualifi ed
workshop. Brake wear depends on the
style of driving, particularly in
the case of vehicles used in
town, over short 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 fl uid level indicates
that the brake pads are worn.
