Installation tips
► To fit the chains during a journey, stop the vehicle on a flat surface on the side of the road.► Apply the parking brake and position any wheel chocks under the wheels to prevent
movement of the vehicle.
► Fit the chains following the instructions provided by the manufacturer.► Move off gently and drive for a few moments, without exceeding 31 mph (50 km/h).► Stop the vehicle and check that the snow chains are correctly tightened.
It is strongly recommended that before
you leave, you practise fitting the snow
chains on a level and dry surface.
Avoid driving with snow chains on roads that have been cleared of snow to avoid
damaging the vehicle's tyres and the road
surface. If the vehicle is fitted with alloy
wheels, check that no part of the chain or its
fixings is in contact with the wheel rim.

Practical information
For more information on the precautions
to take before any work on the 12 V battery, refer to the corresponding section.
Versions equipped with Stop & Start are fitted with a 12 V lead-acid battery of specific technology and specification.
Its replacement should be carried out only by
a CITROËN dealer or a qualified workshop.
Passenger compartment
filter
Depending on the environment and the use of the vehicle (e.g. dusty atmosphere,
city driving), change it twice as often, if
necessary .
A clogged passenger compartment filter
can adversely affect air conditioning
system performance and generate
undesirable odours.
Air filter
Depending on the environment and the use of the vehicle (e.g. dusty atmosphere,
city driving), change it twice as often, if
necessary .
Oil filter
Change the oil filter each time the engine oil is changed.
Particle filter (Diesel)
When the particle filter is approaching saturation, this warning lamp comes on
temporarily, accompanied by a message warning
of the risk of filter clogging.
As soon as the traffic conditions permit,
regenerate the filter by driving at a speed of at
least 37 mph (60 km/h) until the warning lamp goes off.
If the warning lamp stays on, this
indicates a low Diesel additive level.
For more information on Checking levels,
refer to the corresponding section.
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 while
accelerating. This has no impact on the
vehicle’s behaviour or the environment.
New vehicle
During the first few particle filter
regeneration operations, you may notice a
"burning" smell. This is perfectly normal.
Manual gearbox
The gearbox does not require any maintenance (no oil change).
Automatic gearbox
The gearbox does not require any maintenance (no oil change).
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 fluid level indicates that the brake pads
are worn.
After washing the vehicle, moisture, or in wintry conditions, ice can form on the
brake discs and pads: braking efficiency may
be reduced. Gently dab the brakes to dry and
defrost them.
Brake disc wear
For information on checking brake disc
wear, contact a CITROËN dealer or a
qualified workshop.
Manual parking brake
If you notice excessive brake lever travel or decreased effectiveness, the parking
brake must be adjusted, even between two
services.
This system must be checked by a CITROËN
dealer or a qualified workshop.
Wheels and tyres
The inflation pressure of all tyres, including the spare wheel, must be
checked on "cold” tyres.
The pressures indicated on the tyre pressure
label are valid for "cold" tyres. If you have driven
for more than 10 minutes or more than 6 miles
(10 kilometres) at over 31 mph (50 km/h), add 0.3 bar (30 kPa) to the values indicated on the
label.
Under-inflation increases fuel
consumption. Non-compliant tyre
pressure causes premature wear on tyres and
has an adverse effect on the vehicle's road
holding - risk of an accident!
Driving with worn or damaged tyres reduces the
braking and road holding performance of the
vehicle. It is recommended to regularly check the
condition of the tyres (tread and sidewalls) and
wheel rims as well as the presence of the valves.
When the wear indicators no longer appear set
back from the tread, the depth of the grooves is
less than 1.6 mm; it is imperative to replace the
tyres.
Using different size wheels and tyres from those
specified can affect the lifetime of tyres, wheel
rotation, ground clearance, the speedometer
reading and have an adverse effect on road
holding.
Fitting different tyres on the front and rear axles
can cause the ESC to mistime.

diagonally opposite the wheel to be changed.
Never go underneath a vehicle raised using a
jack; use an axle stand.
Wheel with wheel trim
When removing the wheel , first remove
the wheel trim by pulling at the valve aperture
using the wheelbrace.
When refitting the wheel , refit the wheel
trim, starting by placing its aperture in line
with the valve and then pushing it into place
all round its edge with the palm of your hand.


– If the vehicle has steel wheels, remove the wheel trim.– If the vehicle has alloy wheels, remove the central bolt cover using tool 7.– If the vehicle is so equipped, fit security bolt socket 2 to wheelbrace 5 to slacken the security
bolt.
– Slacken the other bolts using the wheelbrace 5 only.

► Place the foot of jack 6 on the ground and ensure that it is directly below the front A or rear B jacking point on the underbody, whichever
is closest to the wheel to be changed.


► Extend jack 6 until its head comes into contact with jacking point A or B; contact area A
or B on the vehicle must be properly inserted
into the central part of the head of the jack.
► Raise the vehicle until there is sufficient space between the wheel and the ground to
admit the spare (not punctured) wheel easily.
Ensure that the jack is stable. If the
ground is slippery or loose, the jack may
slip or collapse - risk of injury!
Take care to position the jack strictly at
one of the jacking points A or B under the
vehicle, ensuring that the head of the jack is
centred under the contact area of the vehicle.
Otherwise, there is a risk of damage to the
vehicle and/or of the jack collapsing - risk of
