CHECK

These regular maintenance

operations will keep your vehicle

in good running order. Consult the

instructions at CITROËN dealerships

or in the servicing booklet enclosed in

the handbook pack.

To maintain the reliability of engines

and emission control systems, the use

of additives in engine oil is prohibited.

Oil change

It is imperative that this is carried out at

the intervals specifi ed and the viscosity

grade of the oil selected must fulfi l the

requirements in accordance with the

manufacturer's servicing schedule.

Consult the instructions at CITROËN

dealerships.
Remove the dipstick before fi lling.
Check the level after fi lling (never

exceed the max mark).
Screw the cap back onto the sump

before closing the bonnet.

LEVELS

If you have to remove/refi t the

engine style cover, handle it with

care to avoid damaging the fi xing

clips.

Dipstick

Warning lights

Oil level

Check the level regularly and top up

between changes. The maximum

consumption is 0.5 litre per 600 miles

(1 000 km).
Check the level with the vehicle level,

engine cold, using the dipstick.

Viscosity selection
In all cases, the oil selected must meet

the manufacturer's requirements.

Checking by means of the

warning lights on the instrument

panel is described in chapter 2,

"Instruments and controls" section.

Changing the brake fluid

The brake fl uid must be changed at

the intervals stated, according to the

manufacturer's servicing schedule.
Use fl uids recommended by the

manufacturer, which fulfi l DOT4

standards.
The level must be between the MIN

and MAX marks on the reservoir.
If fl uid has to be added frequently,

this indicates a failure which must be

checked by a CITROËN dealer as

soon as possible.

There are two marks

on the dipstick:
A = maximum
If you fi ll past this

mark, contact a

CITROËN dealer.
B = minimum
Never allow the level

to fall below this

mark.

Levels

Cooling system

Only use the fl uid recommended by the

manufacturer.
Otherwise, you risk seriously damaging

your engine.
When the engine is warm, the

temperature of the coolant is controlled

by the engine fan. As this fan can

operate with the ignition key removed

and because the cooling system is

pressurised, wait for at least one hour

after the engine has stopped before

carrying out any work.
Slacken the cap by 1/4 of a turn to

release the pressure to prevent any

risk of scalding. When the pressure

has dropped, remove the cap and top

up the level with coolant.
If fl uid has to be added frequently,

this indicates a failure which must be

checked by a CITROËN dealer as

soon as possible.

Power steering fluid level

The vehicle must be parked on level

ground with the engine cold. Unscrew

the cap integrated with the gauge and

check the level which must be between

the MIN and MAX marks.

During regeneration of the particle

emission fi lter, relay noise may be

heard under the fascia.
If the message is still displayed and

the service warning light remains on,

contact a CITROËN dealer.

Diesel additive level (Diesel with

particle emission filter)

When this occurs with the engine running,

this is due to the start of saturation of

the particle emission fi lter (exceptionally

prolonged urban driving conditions: low

speed, long traffi c jams, ...).
In order to regenerate the fi lter, you are

advised to drive at a speed of more than

40 mph (60 km/h) as soon as possible,

when traffi c conditions permit, for at

least fi ve minutes (until the message

disappears and the service warning light

is switched off).

Topping up
The level must be between the MIN

and MAX marks on the expansion

bottle. If more than 1 litre of fl uid is

required to top up the level, have the

system checked by a CITROËN dealer.

Windscreen wash and headlamp

wash level

For best quality cleaning and for your

safety, we would advise that you use

products of the CITROËN range.
To avoid ice forming, do not use water.

Topping up
It is imperative that this additive is

topped up by a CITROËN dealer

without delay.

Used oil

Avoid prolonged contact of used oil

with the skin.
Brake fl uid is harmful to health and

very corrosive.
Do not dispose of used oil, brake

fl uid or coolant into drains or onto

the ground but into the containers

dedicated to this use at CITROËN

dealerships.

The minimum level of this

additive is indicated by

lighting of the service warning

light, accompanied by an

audible signal and a message

on the display.

Checks

CHECK

CHECKS

To check the main levels

and certain components,

in accordance with the

manufacturer's servicing schedule,

refer to the pages of the servicing

booklet which correspond to your

vehicle's engine.

Only use products recommended

by CITROËN or products

of equivalent quality and

specifi cation.

In order to optimise the operation

of units as important as the braking

system, CITROËN selects and offers

specifi c products.
In order to avoid damaging the

electrical units, high pressure washing

to clean the engine compartment is

strictly prohibited.

Oil filter

Change the fi lter regularly, in

accordance with the servicing

schedule.

Refer to the servicing booklet to

fi nd out the replacement interval

for these components.

Depending on the environment

(dusty atmosphere...) and the use of

the vehicle (urban driving...), change

them twice as often if necessary.
Refer to the "Under the bonnet" section

of chapter 6.

Particle emission filter (Diesel)

It is imperative that particle emission

fi lter maintenance is carried out by a

CITROËN dealer.
On acceleration after the vehicle has

been running for a prolonged period

at very low speed or at idle, you may,

in exceptional circumstances, notice

the emission of water vapour at the

exhaust. This water vapour does not

have any adverse effect on vehicle

handling or the environment.

Battery

At the start of winter, have your battery

checked by a CITROËN dealer.

Brake pads

Brake pad wear depends on the style

of driving, in particular for vehicles

which are used in town, over short

distances. It may be necessary to

check the thickness of the pads, even

between services.
Unless there is a leak on the circuit, a

drop in the brake fl uid level indicates

that the brake pads are worn.

Brake disc/drum wear status

For any information relating to

checking the brake disc/drum wear

status, contact a CITROËN dealer.

Handbrake

Where the handbrake travel is too

great or there is a reduction in the

performance of the system, the

handbrake should be adjusted, even

between services.
Have the system checked by a

CITROËN dealer.

Carbon filter and passenger

compartment filter

The carbon fi lter permits continuous

and effective fi ltering of dust.
If the passenger compartment fi lter

becomes clogged, this may reduce

the performance of the air conditioning

system and generate unpleasant

odours.
We recommend the use of a combined

passenger compartment fi lter. By

means of its second special active

fi lter, it contributes to the purifi cation

of the air breathed by the occupants

and to the cleanness of the passenger

compartment (reduction of allergic

symptoms, unpleasant odours and

greasy deposits).

Manual gearbox

Have the level checked in accordance with

the manufacturer's servicing schedule.

Battery

ECONOMY MODE FUNCTION
