40 years

of passion

The strength of the partnership between

TOTAL and CITROËN is demonstrated in

particular through motor sport: from the

1969 Morocco Rally to the superb double

victory for TEAM CITROËN TOTAL and

Sébastien LOEB and Daniel ELENA in

the 2009 World Rally Championship.

The impressive list of awards for the

two marques has been built up through epic

battles, fought in extreme conditions. These

trials permit arduous testing of the TOTAL

lubricants, assuring the performance of

CITROËN vehicles.

Checks

Checking levels

Check all of these levels regularly and top them up if necessary, unless otherwise indicated.

If a level drops significantly, have the corresponding system checked by a CITROËN dealer or a qualified workshop.

Brake fluid level

When working under the bonnet, take

care, as certain areas of the engine

may be extremely hot (risk of burns).

The brake fluid level should be close

to the "MAX" mark. If it is not, check

the brake pad wear.

Oil level

The reading will only be correct if

the vehicle is on level ground and

the engine has been off for more than

30 minutes.

Engine oil change

Refer to the servicing booklet 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.

Changing the ßuid

Refer to the Maintenance and Warranty Guide

for the interval for this operation.

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.

Oil speciÞcation

Fluid speciÞcation

It is normal to top up the oil level

between two services. CITROËN

recommends that you check the oil

level, and top up if necessary, every

3 000 miles (5 000 kilometres).

The oil must correspond to your engine

and conform to the manufacturer's

recommendations.

The brake fluid must conform to the

manufacturer's recommendations and meet

the DOT4 standard.

Power steering fluid level

Screenwash/headlamp wash

level

The power steering fluid level should

be close to the "MAX" mark. Unscrew

the cap, with the engine cold,

to check the level.

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.

To check the level or top up the

fluid on vehicle fitted with headlamp

washers, immobilise the vehicle and

switch of the engine.

Coolant level

Changing the coolant

The coolant does not have to be changed.

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 ignition off.

On vehicles which are fitted with a particle

emission filter, the fan may operate after

the vehicle has been switched off, even if

the engine is cold.

Coolant speciÞcation

The coolant must conform to the

manufacturer's recommendations.

SpeciÞcation of the ßuid

Topping up

To ensure optimum cleaning and to avoid

freezing, the fluid should never be topped up or

replaced by plain water.

The reservoir must be topped up without delay

by a CITROËN dealer or a qualified workshop.

Checks

Unless otherwise indicated, check these components in accordance with the servicing booklet and according to your engine.

Otherwise, have them checked by a CITROËN dealer or a qualified workshop.

Battery

Air filter and passenger compartment filter

The battery does not require any

maintenance.

However, check that the terminals

are clean and correctly tightened,

Refer to the servicing booklet for

details of the replacement intervals

for these components.

Depending on the environment

particularly in summer and winter.

(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 filter may

have an adverse effect on the performance

of the air conditioning system and generate

undesirable odours.

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.

The presence of this label, in particular with

the Stop & Start 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 observe this recommendation may

shorten the life of the battery.

Oil filter

Replace the oil filter each time

the engine oil is changed.

Refer to the servicing booklet for

details of the replacement interval for

this component.

goes off.

If the warning lamp stays on, refer to

Brake wear depends on the style

If a loss of effectiveness of this

system is noticed, the parking brake

must be checked, even between

two services.

Only use products recommended by

CITROËN or products of equivalent

quality and specification.

of units as important as the braking

system, CITROËN selects and offers

very specific products.

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 fluid level indicates that the brake

pads are worn.

Checking this system must be done by a

CITROËN dealer or a qualified workshop.

Brake disc wear

For information on checking brake

disc wear, contact a CITROËN dealer

or a qualified workshop.

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.
