Practical information
Topping up the engine oil level

► Remove the dipstick before topping up.
► Recover the oil filler neck.
► Unscrew the filler cap.
► Install the oil filler neck in the filler hole.
► Top up with oil.
► Remove the oil filler neck from the filler hole.
► Replace the filler cap.
► Replace the dipstick.
Brake fluid
The level of this fluid should be close to
the "MAX" mark. If not, check the brake
pad wear.
The Diesel circuit is under very high pressure.
All work on this circuit must be carried out
only by a CITROËN dealer or a qualified
workshop.
Checking levels
Check all of the following levels regularly in
accordance with the manufacturer's service
schedule. Top them up if required, unless
otherwise indicated.
If a level drops significantly, have the
corresponding system checked by a CITROËN
dealer or a qualified workshop.
The fluids must comply with the manufacturer's requirements and with
the vehicle's engine.
Take care when working under the bonnet, as certain areas of the engine
may be extremely hot (risk of burns) and the
cooling fan could start at any time (even with
the ignition off).
If the engine cover is to be removed /
refitted, handle it with care to avoid
damaging the mounting clips.
Used products
Avoid prolonged contact of used oil or fluids with the skin.
Most of these fluids are harmful to health and
very corrosive.
Do not discard used oil or fluids into
sewers or onto the ground.
Empty used oil into the containers reserved
for this purpose at a CITROËN dealer or a
qualified workshop.
Engine oil
The level is checked, with the engine having been switched off for at least 30
minutes and on level ground, using the dipstick.
It is normal to top up the oil level between two
services (or oil changes). It is recommended
that you check the level, and top up if necessary,
every 3,000 miles (5,000 km).
In order to maintain the reliability of the
engine and emissions control system,
never use additives in the engine oil.
Checking using the dipstick
For the location of the dipstick, please refer
to the illustration of the corresponding engine
compartment.
► Grasp the dipstick by its coloured grip and
pull it out completely.
► Wipe the end of the dipstick using a clean,
lint-free cloth.


► Reinsert the dipstick and push fully down,
then pull it out again to visually check the oil
level: the correct level is between marks A (max)
and B (min).
Do not start the engine if the level is:
– above mark A: contact a CITROËN dealer or a
qualified workshop.
– 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 and
qualified workshops).
Use of non-recommended oil may invalidate
the contractual warranty in the event of
engine failure.

Practical information
reading and have an adverse effect on road
holding.
Fitting different tyres on the front and rear axles
can cause the ESC to mistime.
AdBlue® (BlueHDi
engines)


To respect the environment and ensure
compliance with the Euro 6 standard, without
adversely affecting the performance or fuel
consumption of its Diesel engines, CITROËN
has taken the decision to equip its vehicles
with a system that associates SCR (Selective
Catalytic Reduction) with a Diesel Particle Filter
(DPF) for the treatment of exhaust gases.
SCR system
Using a liquid called AdBlue® that contains
urea, a catalytic converter turns up to 85% of
the nitrogen oxides (NOx) into nitrogen and
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.
Diesel fuel filter
The Diesel fuel filter is located under the bonnet,
close to the brake fluid reservoir.
If this warning lamp comes on, the filter
must be purged to remove water.
You can also purge the fuel filter regularly, every
time the engine oil is changed.
Bleeding the water in the filter

► Couple a clear hose to the bleed screw
1head.
► Place the other end of the clear hose in a
container.
► Loosen bleed screw 2.
► Switch on the ignition.
► Wait for the scavenge pump to stop.
► Switch off the ignition.
► Tighten bleed screw 2.
► Remove, then drain the clear hose and the
container.
► Start the engine.
► Check that there are no leaks.
HDi engines make use of advanced
technology. Any intervention requires a
special qualification guaranteed by the
CITROËN dealer network 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

In the event of a breakdown
8Changing a bulb
The headlamps have polycarbonate lenses with a protective coating:
► do not clean them using a dry or
abrasive cloth, nor with a detergent or
solvent product,
► 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 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 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
with the same type and specification.
In some weather conditions (e.g. low
temperature or humidity), the presence
of misting on the internal surface of the glass
of the headlamps and rear lamps is normal; it
disappears after the lamps have been on for a
few minutes.
Types of bulb
Various types of bulb are fitted on the vehicle. To
remove them:


Type A All-glass bulb: pull gently as it is fitted by
pressure.
Type B Bayonet bulb: press on the bulb then
turn it anti-clockwise.
Type C Cylindrical bulb: ease the contacts apart.
Type D Halogen bulb: release the retaining
spring from its housing.
