CHECKS

Particle emission filter (Diesel)

The start of saturation of the particle

emissions fi lter is indicated by:

fi xed illumination of the par-

ticle emissions fi lter warning

lamp, accompanied by an

audible 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 specifi -

cation. The involvement of a CITROËN

dealer or a qualifi ed workshop is essen-

tial when replacing or disconnecting the

battery.

On a new vehicle, the fi rst op-

erations of regeneration of the

particle emissions fi lter may be

accompanied by the smell of

"burning", which is perfectly nor-

mal.
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.

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.

Unless otherwise indicated, check

these components in accordance with

the maintenance and warranty guide

and according to your engine.
Otherwise, have them checked by a

CITROËN dealer or a qualifi ed work-

shop.

Air filter and passenger compartment filter

Refer to the maintenance and

warranty guide for details of

the replacement intervals for

these components.
Depending on the environ-

ment (e.g. dusty atmosphere)

and the use of the vehicle

(e.g. city driving),

replace

them twice as often if necessary .
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.

Oil filter

Replace the oil fi lter each time

the engine oil is changed.
Refer to the maintenance and

warranty guide for details of

the replacement interval for

this component.

12 V 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 "12 V battery" section for

details of the precautions to be taken

before disconnecting the battery and

following its reconnection.

Automatic gearbox

The gearbox does not require

any maintenance (no oil change).
Refer to the maintenance and

warranty guide for details of

the level checking interval for

this component.

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 qualifi ed work-

shop.

Manual parking brake

Only use products recommended

by CITROËN or products of equiva-

lent quality and specifi cation.
In order to optimise the opera-

tion of units as important as

those in the braking system,

CITROËN selects and offers

very specifi c products.
After washing the vehicle, damp-

ness, or in wintry conditions, ice

can form on the brake discs and

pads: braking effi ciency may be

reduced. Make light brake ap-

plications to dry and defrost the

brakes.

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.

Brake pads

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 circuit, a

drop in the brake fl uid level indicates

that the brake pads are worn.

Brake disc wear

For information on checking

brake disc wear, contact a

CITROËN dealer or a quali-

fi ed workshop.

For more information, refer to the "Electric

parking brake - Operating faults" section.

Manual gearbox

The gearbox does not re-

quire any maintenance (no oil

change).
Refer to the maintenance and

warranty guide for the details

of the level checking interval

for this component.

Electronic gearbox

The gearbox does not require

any maintenance (no oil change).

Tyre under-infl ation detection
If the vehicle is fi tted with tyre under-

infl ation detection, the under-infl ation

warning lamp will remain on after the

wheel has been repaired until the

system is reinitialised by a CITROËN

dealer or a qualifi ed workshop.

If after around 5 to 7 minutes the

pressure is not attained, this in-

dicates that the tyre is not repair-

able; contact a CITROËN dealer

or a qualifi ed workshop for as-

sistance.

 Switch on the compressor by mov-

ing the switch B to position "I" until

the tyre pressure reaches 2.0 bars.

The sealant is injected into the tyre

under pressure; do not disconnect

the pipe from the valve during this

operation (risk of splashing).

 Remove the kit and screw the cap

back on the white pipe.

Take care to avoid staining your ve-

hicle with traces of fl uid. Keep the

kit to hand.

it has been programmed to au-

tomatic mode, switch off the ig-

nition and engage fi rst gear * to

lock the wheels.
Check that the braking warning

lamps in the instrument panel

are on (not fl ashing).
The occupants must get out of

the vehicle and wait where they

are safe.
If necessary, place a chock un-

der the wheel diagonally oppo-

site the wheel to be changed.
Never go underneath a vehicle

raised using a jack; use an axle

stand.

SNOW CHAINS

In wintry conditions, snow chains improve traction as well as the behaviour of the vehicle when braking.

Advice on installation
 If you have to fi t the chains during

a journey, stop the vehicle on a fl at

surface on the side of the road.

 Apply the parking brake and posi-

tion any wheel chocks to prevent

movement of your vehicle.

 Fit the chains following the instruc-

tions provided by the manufacturer.

 Move off gently and drive for a

few moments, without exceeding

30 mph (50 km/h).

 Stop your vehicle and check that

the snow chains are correctly tight-

ened.

The snow chains must be fi tted

only to the front wheels. They

must never be fi tted to "space-

saver" type spare wheels.

Take account of the legislation in

force in your country on the use

of snow chains and the maxi-

mum running speed authorised.

Avoid driving on roads that

have been cleared of snow, to

avoid damaging your vehicle's

tyres and the road surface. It is

recommended that before you

leave, you practise fi tting the

snow chains on a level and dry

surface. If your vehicle is fi tted

with alloy wheels, check that no

part of the chain or its fi xings is

in contact with the wheel rim.

Use only the chains designed to be fi t-

ted to the type of wheel fi tted to your

vehicle:
