Practical information
– below mark B : top up the engine oil
immediately.
Oil grade
Before topping up or changing the engine
oil, check that the oil is suitable for the engine
and complies with the recommendations in
the service schedule supplied with the vehicle
(or available from your CITROËN dealer).
Use of non-recommended oil may invalidate
the contractual warranty in the event of
engine failure.
Topping up the engine oil level
For the location of the engine oil filler cap, please
refer to the corresponding under-bonnet engine
compartment illustration.
►

Add oil in small quantities, avoiding any spills
on engine components (risk of fire).
►


W
ait a few minutes before checking the level
again using the dipstick.
►

T
op up the level if necessary.
►

After checking the level, carefully screw the
oil filler cap back on

and replace the dipstick in
its tube.
Within 30 minutes of adding oil, the oil
level indication in the instrument panel
when the ignition is switched on is not valid.
Brake fluid
The level of this fluid should be close to
the "MAX" mark. If not, check the leakage
in the circuit and the brake pad wear.
To know how often the brake fluid should be
replaced, refer to the manufacturer's servicing
schedule.
Clean the cap before removing it to refill.
Use only DOT3 or DOT4 brake fluid from
a sealed container.
Engine coolant
It is normal to top up this fluid between
two services.
The check and top-up must only be done with
the engine cold.
A low level presents a risk of serious damage to
the engine.
The level of engine coolant should be close to
the "MAX" mark but should never exceed it.
If the level is close to or below the " MIN” mark, it
is essential to top up.
When the engine is hot, the temperature of
engine coolant is regulated by the fan.
As the cooling system is pressurised, wait at
least one hour after switching off the engine
before carrying out any work.
In order to avoid the risk of burning, if you need
to top up in an emergency, wrap a cloth around
the cap and unscrew the cap by two turns to
allow the pressure to drop.
Once the pressure has dropped, remove the cap
and top up to the required level.
Screenwash fluid
Top up to the required level when necessary.
Fluid specification
The fluid must be topped up with a ready-to-use
mixture.
In winter (temperatures below zero), a liquid
containing an agent to prevent freezing must
be used which is appropriate for the prevailing
conditions, in order to protect the elements of the
system (pump, tank, ducts, jets, etc.).
Filling with pure water is prohibited under
all circumstances (risk of freezing,
limestone deposits, etc.).

In the event of a breakdown
8Removing a wheel
Parking the vehicle
Immobilise the vehicle where it does
not obstruct traffic: the ground must be level,
stable and non-slippery.
With a manual gearbox, engage first gear to
lock the wheels, apply the parking brake and
switch off the ignition.
Check for the fixed illumination of the parking
brake indicator lamps in the instrument panel.
The occupants must get out of the vehicle
and wait where they are safe.
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 an axle stand.
Wheel with wheel trim
When removing the wheel , first remove
the wheel trim by pulling at the valve aperture.
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.
Wheel nuts removing pattern

► Loosen the nuts on the wheel in diagonal
sequence. Do not remove wheel nuts.


► Slacken the bolts using the wheel wrench 3
only.


► Place the foot of jack 1 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 1 with the jack handle 2 and
wheel wrench 3 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

.

In the event of a breakdown
8► Tighten the spare wheel fixing screw by a few
turns.
After changing a wheel
The temporary spare wheel is only intended for temporary emergency use,
until the conventional wheel can be repaired
or replaced.
Continuous use of this spare can result in tire
failure and loss of control. Always observe
these precautions when using this spare:
–

Y

our vehicle will respond differently with
this temporary spare.
–

Do not exceed 80 km/h speed.
–


Replace this spare with a standard tire and
wheel as soon as possible.
–


Use of this spare will reduce ground
clearance.
–


Set the specified tire pressure indicated
on the tire information label located on the
driver's door lock pillar

.
–

Do not use tire chains on the temporary
spare. If you must use tire chains, rearrange
the wheels so standard tires and wheels are
fitted to the front axle.
–


The temporary spare wheel has a much
shorter tread life than the conventional

wheels
on your vehicle. Replace the tire as soon as
possible as the tread wear indicator appears.
The inflation pressure of the temporary spare
wheel should be checked at least monthly. At
the same time, check that the tire is stored
securely. If it is not, tighten it.
Note that two or more temporary spare
wheels should not be used on one vehicle
simultaneously.
Changing a bulb
In some weather conditions (e.g. low
temperature or humidity), misting on the
internal surface of the glass of the headlamps
and rear lamps is normal, and will disappear
after the lamps have been on for a few
minutes.
The headlamps have polycarbonate lenses with a protective coating:
–

Do not clean them with a dry or abrasive
cloth, nor with detergent or solvent
products.
–


Use a sponge and soapy water or a pH
neutral product.
–


When using a high-pressure washer on
persistent marks, do not keep the lance
directed towards the headlamps, lamps or
their edges for too long, so as not to damage
their protective coating and seals.
Changing a bulb must only be done with
the ignition off and after the headlamp /
lamp has been switched off for several
minutes - risk of serious burns!
Do not touch the bulb directly with your
fingers; use a lint-free cloth.
It is essential only to use anti-ultraviolet
(UV) type bulbs, so as not to damage the
headlamp.
Always replace a failed bulb with a new bulb
of the same type and specification. To avoid
lighting imbalance, replace the bulbs in pairs.
Refitting the lamp units
Perform the operations in the reverse
order to dismantling.
Opening the bonnet / Accessing the
bulbs
With the engine warm, proceed with caution -
risk of burns!
Take care with objects or clothing that could
be caught in the blades of the cooling fan -
risk of strangulation!
Halogen bulbs (Hx)
To ensure good quality lighting, check
that the bulb is correctly positioned in its
housing.
