FUEL

FUEL QUALITY

A label inside the ﬁller ﬂap tells you

which type of fuel to use.

V

A

Quality of the fuel used for

Diesel engines

The Diesel engines are perfectly

compatible with biofuels which

conform to current and future

European standards (Diesel fuel

which complies with standard EN

590 mixed with a biofuel which

complies with standard EN 14214)

which can be distributed at the

pumps (possible incorporation of

0 to 7 % Fatty Acid Methyl Ester).

The use of any other type of (bio)

fuel (vegetable or animal oils,

domestic fuel oil, etc.) is strictly

prohibited (risk of damage to the

engine and fuel circuit).

A

While you are refuelling, the

engine must be stopped and the

ignition switched off.

When you are seeking to ﬁll your

tank, do not persist after the

third cut-off; that could cause

your vehicle to malfunction.

Fuel must be added in quantities

of more than 5 litres to be recog-

nised by the fuel gauge.

To open the ﬂap, press button A

Undo the cap and attach it to the

tab on the inside of the ﬂap.

Opening the cap can trigger a vac-

uum. This results in a noise caused

by the sealing of the fuel circuit.

Note: The fuel ﬂap is locked when

you lock your vehicle with the

remote control.

If you should put in fuel that is not suitable for your vehicle's

engine type, it is imperative to have the tank drained before

you start the engine again.

after a while (when the functions

have been on for a few minutes for

example).

If this is not the case, contact a

CITROËN dealer or a qualiﬁed

workshop.

For repairs to the front lamp units

and for bulb replacement, contact

a CITROËN dealer or a qualiﬁed

workshop. The bulbs for lamps D

and E have a common bulb-

holder.

Your headlamps have Xenon bulbs.

Because of the risk of electrocution, we recommend that

you contact a CITROËN dealer or a qualiﬁed workshop in the

event of a fault.

It is recommended to change both bulbs at the same time if

there is a failure of one of them.

Your vehicle is equipped with an active bonnet. To ensure the

correct operation of this safety equipment, contact a CITROËN

dealer or a qualiﬁed workshop for the replacement of any part of

the front panel.

SAFETY RECOMMENDATIONS

MAINTENANCE

if cleaning the vehicle with a high

pressure system

TOWBAR

(Boat, caravan, etc.)

It is recommended that towbar

installation and removal be done

by a CITROËN dealer or a quali-

ﬁed workshop.

If you are climbing a steep gradient

and the engine gets excessively

hot, certain functions become una-

vailable (e.g. sequential control of

the automatic gearbox, the air con-

ditioning).

If you are towing, it is necesaary

to deactivate the parking assist-

ance by pressing the control on the

dashboard. See "Parking assist-

ance".

V

•

Your Piloted Deﬂector has to

be closed.

It is not advisable to clean the

underside of the vehicle, for

fear of damaging the electric

parking brake.

•

As water may penetrate into

the vehicle interior via the door

apertures, do not target these

r

.

Do not direct at the headlamps,

lamps and their edges for too

long or you may damage their

coating and seals.

It is recommended that you remove

the towing ball, so that it does not

interfere with the functioning of the

proximity sensors, when you are

not using a trailer.

A

Dimensions (in metres):

A: 0.971

It is recommended that towbar installation and removal be

done by a CITROËN dealer or a qualiﬁed workshop.

If you are towing another vehicle, the latter must be free-

wheeling (gearbox in neutral).

138

ROOF BARS

IMPORTANT

For your safety and to avoid damage to the roof, you should use roof bars that are tested and approved by CITROËN

for the design of your particular vehicle.

V

INSTALLATION

Four ﬁxing points are provided on your vehicle.

Recommendations:

•

Spread the load evenly, avoiding overloading on

one side.

Position the heaviest weight as low down as pos-

sible.

Tie the load down securely and add warning signs

if it is protruding.

Drive conservatively, as the vehicle will be more

vulnerable to side winds.

The stability of your vehicle may be altered.

•

Remove the roof rack or roof bars when you are

not using them.

Do not exceed the maximum permitted

load.

For the maximum distributed load on the

roof bars: see the chapter "General".

139

COLD WEATHER SHIELD

in the protection box in the spare

wheel. See "Changing a wheel".

Before ﬁtting

After ﬁtting

The snow-guard delivered with the vehicle (according

REMOVAL

1. Park the vehicle on stable, ﬁrm ground that is not slippery. Apply the

parking brake.

V

2. It is essential to make sure that the occupants have left the vehicle and

are in a place where their safety is guaranteed.

3. With the engine idling, adjust the ground clearance to maximum height.

See "Comfort" and "Ground clearance adjustment". Switch off the igni-

tion and engage ﬁrst gear or reverse gear depending on any slope (for

a vehicle with automatic gearbox, select position P).

4. Position the chock at the wheel that is diametrically opposite the one to

be replaced.

5. Position the jack at one of the four jacking-points provided on the sub-

frame close to the wheels, then use the handle to unwind the jack until

it reaches the ground.

6. Slide the removal tool 4 into the notch and lever vigorously to detach

the anti-theft bolt protector. See illustration. You can use the handle at

the extremity of the tool 4

7. Slacken the wheel bolts.

8. Continue to extend the jack until the wheel is a few centimetres off the

ground.

9. Undo the bolts, remove the wheel.

Before positioning the jack, always adjust the vehicle's ground

clearance to the "maximum height" position and retain this

adjustment for as long as the jack is under the vehicle (do not

use the hydraulic adjustments).

Never get underneath the vehicle if it is supported only by the

jack.

The jack and all the tools are designed speciﬁcallyfor use on your

particular vehicle. Do not use them for any other applications.

Have the original wheel repaired and refitted as soon as

possible.

It is imperative not to exceed a speed of 80 km/h (50 mph) on

the spare wheel.

between the hub and the wheel

is clean.

2. Screw in the bolts but do not

fully tighten them.

3. Lower the jack and remove it.

4. Tighten the wheel bolts, using

the wheelbrace.

WHEEL EQUIPPED WITH DEFLATION

DETECTION SENSOR

sensors. Have it repaired by a

CITROËN dealer or a qualiﬁed

workshop.

V

ANTI-THEFT BOLTS

Each wheel is equipped with one

anti-theft bolt.

To remove it

1. Remove the protector that is

covering it by means of the

tool 4 for "removing anti-theft

protectors".

5. Reﬁt the embellisher.

WHEEL FOR TEMPORARY USE

6. Return the ground clearance

to the normal position. See

"Ground clearance adjustment".

7. Ensure the tyre pressure

is correct (see "Vehicle

identiﬁcation") and have the

balancing checked.

If your vehicle is equipped with a

spare wheel for temporary use

only, when ﬁtting it it is normal to

observe that the wheel bolts do not

come to bear on the wheel rim.

The spare wheel is secured by the

conical tapering of the wheel bolt’s

shaft. See illustration.

When reﬁtting the original wheel,

ensure that the wheel bolt contact

surfaces are clean and in good

condition.

2. Use the anti-theft socket with

the handle.

It is imperative not to exceed a speed of 80 km/h (50 mph) on

the spare wheel.

The wheel bolts are speciﬁc to the type of wheel.

When replacing wheels, check with a CITROËN dealer or a

qualiﬁed workshop that the wheel bolts are compatible with

the new wheels.

Note: take care to note down the code number engraved on the

head of the anti-theft bolt socket. This will enable you to obtain

replacement anti-theft bolt sockets from a dealership.

ADVICE

Towing at low speed over a very

short distance is authorised in

exceptional cases depending on

the regulations in force.

V

Otherwise, it is necessary to

have your vehicle transported

on a recovery truck.

It is essential to check that the

electric parking brake is released.

For the rear cover, press on the right hand side.

The ignition key must be in position M to retain steering.

Use a bar with attachments to the towing eyes as above.

The towing eye is removable, to be stowed in the jack protection box inside

the spare wheel.

When the engine is not running, the steering and the braking

are no longer assisted.

If you are towing another vehicle, the latter must be free-

wheeling (gearbox in neutral).

Towing with "front or rear lifted"
