Removing a wheel
Parking the vehicle
Immobilise the vehicle where it does not
block traffic: if possible, park the vehicle
on level, stable and non-slippery
ground.
Apply the parking brake, switch off the
ignition and engage first gear to lock
the wheels.
If necessary, place a chock under the
wheel diagonally opposite the wheel to
be changed.
Never go underneath a vehicle raised
using a jack; use a stand.
List of operations

Fitting a wheel
After changing a wheel
When using the "space-saver" spare
wheel, do not exceed a speed of
50 mph (80 km/h).
Have the tightening of the bolts and the
pressure of the spare wheel checked
by a CITROËN dealer or a qualified
workshop without delay.
Have the punctured wheel repaired and
replace it on the vehicle as soon as
possible.
List of operations
F Put the wheel in place on the hub.
F S crew in the bolts fully by hand.
F

P
re-tighten the security bolt using the
wheelbrace 1 fitted with the security
socket
5

(if your vehicle is equipped with
security wheel bolts).
F

P
re-tighten the other bolts using the
wheelbrace 1 o n l y.
Fitting snow tyres
If you equip your vehicle with snow
tyres fitted on steel wheel rims, special
bolts available from your CITROËN
dealer or a qualified workshop must
be used.
If the replacement of a tyre is
necessary on 4-wheel drive versions,
it is recommended that all four tyres be
replaced at the same time, ensuring
that the same make, model and size is
used on all wheels.
This is because using tyres of different
sizes, structure or rate of wear could
damage transmission components.

For more information on snow chains,
contact a CITROËN dealer or a
qualified workshop.
Snow chains
In wintry conditions, snow chains improve traction as well as the behaviour of the vehicle when
braking.
Advice on installation
F If you have to fit the chains during a journey, stop the vehicle on a flat sur face
on the side of the road.
F

A
pply the parking brake and position any
wheel chocks to prevent movement of
your
vehicle.
F

F
it the chains following the instructions
provided by the manufacturer.
F

M
ove off gently and drive for a few
moments, without exceeding 30 mph
(50
km/h).
F

S
top your vehicle and check that the snow
chains are correctly tightened.
The snow chains must be fitted only
to the front wheels. They must never
be fitted to "space-saver" type spare
wheels.
Take account of the legislation in force
in your country on the use of snow
chains and the maximum running speed
authorised.
Avoid driving with snow chains on roads
that have been cleared of snow, to
avoid damaging your vehicle's tyres and
the road sur face. If your vehicle is fitted
with alloy wheels, check that no part of
the chain or its fixings is in contact with
the wheel rim.Use only chains designed for fitment to the type
of road wheels on your vehicle:
Original equipment tyre size Maximum link size
215/70 R16 12 mm
225/55 R18
It is strongly recommended that before
you leave, you practise fitting the snow
chains on a level and dry sur face.

Changing a bulb
For bulbs that have alignment
lugs (H1, H7...) ensure that they are
fitted correctly for the best lighting
performance.
The headlamps have polycarbonate
lenses with a protective coating:
F

d

o not clean them using a dr y
or abrasive cloth, nor with a
detergent or solvent product,
F

u

se a sponge and soapy water,
F

w

hen using a high pressure washer
on persistent marks, do not keep
the lance directed towards the
lamps or their edges for too long,
so as not to damage their protective
coating and seals.
F

D

o not touch the bulb directly with
your fingers, use lint-free cloths.
Changing a bulb should only be done
after the headlamp has been switched
off for several minutes (risk of serious
burns).
It is imperative to use only anti-
ultraviolet (UV) type bulbs in order not
to damage the headlamp.
Always replace a failed bulb with a
new bulb with the same type and
specification.
Risk of electrocution
Replacement of the xenon bulbs
(D1S-35W) must be carried out by
a CITROËN dealer or a qualified
workshop.
