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.

Fitting roof bars
The transverse roof bars are fitted to the longitudinal bars at the 8 fixing points masked by covers.
Using a small screwdriver, remove the 8 covers on the inner faces of the longitudinal bars.
The transverse bars are fitted directly to the roof of the vehicle, at the 4 anchorage points masked
by covers.
Slide the covers towards the front of the vehicle to remove them.
Retain the protective covers.
After removing the roof bars, the protective covers should be refitted:
F
i
nsert the fixing tongues into the apertures then slide the covers towards the rear of the vehicle. The body sill finishers should not be
used as a step when fitting roof bars.Use accessories recommended by
CITROËN and follow the accessory
manufacturer's fitting instructions.
Maximum authorised weight on the roof
bars, for a loading height not exceeding
40
cm (except bicycle carriers): 80 kg.
If the height exceeds 40 cm, adapt the
speed of the vehicle to the condition of
the road, to avoid damaging the roof
bars and the fixings on the roof.
Please refer to national legislation to
comply with the regulations regarding
the transportation of objects which are
longer than the vehicle.
For reasons of safety and to avoid damaging the roof, it is essential to use transverse bars that are
approved for your vehicle.

Avoid prolonged contact of used oil or
fluids with the skin.
Most of these fluids are harmful to
health or indeed very corrosive.
Do not discard used oil or fluids into
sewers or onto the ground.

a qualified workshop (France) or to an
authorised waste disposal site.

Checking components
12 V battery
Electrolyte level
For access to the 12 V Battery, refer
to the corresponding section. Refer to the manufacturer's
service schedule for details of the
replacement intervals for these
components.
Air filter and passenger compartment filter
Replace the oil filter each time the
engine oil is changed.
Refer to the manufacturer's
service schedule for details of
the replacement interval for this
component.
Oil filter
If necessary, top up using distilled water,
removing the battery cap from each cell.
Check the electrolyte level at least once a
month.
When carrying out work on the 12 V
Battery,
refer to the corresponding section for
details of the precautions to be taken before
disconnecting the battery and following its
reconnection.
Unless other wise indicated, check these components in accordance with the manufacturer's service schedule and according to your engine.
Other wise, have them checked by a CITROËN dealer or a qualified workshop.
The electrolyte level must be between the
"LOWER LEVEL" and "UPPER LEVEL" marks.
Depending on the environment (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 filter may
have an adverse effect on the per formance
of the air conditioning system and generate
undesirable odours.

Manual gearbox
For servicing of the gearbox, refer to
the manufacturer's service schedule
for details of the interval for checking
this component.
"CVT" gearbox
For servicing of the "CVT" gearbox,
refer to the manufacturer's service
schedule for details of the interval for
checking this component.
Particle filter (Diesel)
The start of saturation of the particle filter is
indicated by the temporary illumination of this
warning lamp, accompanied by a message in
the instrument panel screen.As soon as the traffic conditions permit,
regenerate the filter by driving at a
speed of at least 25 mph (40 km/h) for
about 20 minutes (with the 1.6 litre HDi
engine, the minimum speed is 37 mph
(60 km/h)).
If the warning lamp stays on, this
indicates a low additive level.
For more information on Checking
levels
and the Diesel additive level in
particular, refer to the corresponding
section.
On a new vehicle, the first particle
filter regeneration operations may be
accompanied by a "burning" smell,
which is per fectly normal.
Following prolonged operation of the
vehicle at very low speed or at idle,
you may, in exceptional circumstances,
notice the emission of water vapour at
the exhaust on acceleration. This does
not affect the behaviour of the vehicle
or the environment.

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.
Brake pads
For information on checking brake
disc wear, contact a CITROËN dealer
or a qualified workshop.
Brake disc wearParking brake
If excessive travel or 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.
In order to optimise the operation of
units as important as those in the
braking system, CITROËN selects and
offers very specific products.
After washing the vehicle, dampness,
or in wintry conditions, ice can form
on the brake discs and pads: braking
efficiency may be reduced. Make light
brake applications to dry and defrost
the brakes.
Checking this system must be done by a
CITROËN dealer or a qualified workshop.
Unless there is a leak in the circuit, a drop in
the brake fluid level indicates that the brake
pads are worn.
