support slot.
►

Clip the stay in its housing.
► Lower the bonnet and release it near the end
of its travel.
►

Pull on the bonnet to check that it is locked
correctly

.
Because of the presence of electrical
equipment under the bonnet, it is strongly
recommended that exposure to water (rain,
washing, etc.) be limited.

For more information on the Charging system
(Electric), refer to the corresponding section.
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).
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, either using the oil
level indicator in the instrument panel when the
ignition is switched on (for vehicles equipped
with an electric gauge), or 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.

Opening the bonnet/Accessing the
bulbs
Proceed with caution when the engine is hot -
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.
Main/Dipped beam headlamps


► Remove the protective cover by pulling on
the tab.
►

Disconnect the bulb connector
.
►

Remove the bulb and replace it.
T

o refit, carry out these operations in reverse
order, directing the bulb’s positioning lug
downwards.
Direction indicators
Rapid flashing of the indicator lamp for a
direction indicator (left or right) indicates
that one of the bulbs on the corresponding
side has failed.


► Turn the connector a quarter turn
anti-clockwise.
►

Pull the bulb connector
.
►

Remove the bulb and replace it.
Amber-coloured bulbs must be replaced by bulbs with identical specifications and
colour.

In the event of a breakdown
For more information, refer to the
handbook.
Explosive gases can be present close to
the battery.
Accessing the battery
The battery is located under the bonnet.

For access to the (+) terminal:
► Release the bonnet by pulling the internal
release lever
, then the external safety catch.
►

Raise the bonnet.
(+)

Positive terminal with a quick-release
terminal.
(-) Negative terminal.
Starting using another
battery
If the vehicle's battery is flat, the engine can be
started using a backup battery (either external or
from another vehicle) and jump leads or using a
battery booster.
Never start the engine by connecting a
battery charger.
Never use a 24
V or higher battery booster.
Check beforehand that the backup battery
has a nominal voltage of 12 V and a capacity
at least equal to that of the discharged
battery.
The two vehicles must not be in contact with
each other.
Switch off all electricity-consuming equipment
on both vehicles (audio system, wipers,
lighting, etc.).
Make sure that the jump leads are well away
from the engine’s moving parts (fan, belt,
etc.).
Do not disconnect the (+) terminal while the
engine is running.


► Lift the plastic cover on the (+) terminal, if the
vehicle has one.
►

Connect the red cable to the (+) terminal of
flat battery

A (at the metal elbow), then to the
(+) terminal of the backup battery
B or of the
booster.
►

Connect one end of the green or black cable
to the (-) terminal of the backup battery

B or of
the booster (or to an earth point on the assisting
vehicle).
►
Connect the other end of the green or black
cable to the (-) terminal of flat battery

A.
►

Start the engine on the assisting vehicle and
leave it running for a few minutes.
►


Operate the starter on the broken down
vehicle and let the engine run.
If the engine does not start immediately

, switch
off the ignition and wait a few moments before
trying again.
►

W
ait for it to return to idle.
►

Disconnect the jump leads in reverse order.
►


Refit the plastic cover to the (+) terminal, if
the vehicle has one.
►


Allow the engine to run for at least
30

minutes, with the vehicle stationary, so that
the battery reaches an adequate state of charge.
Driving immediately without having
reached a sufficient level of charge may
affect some of the vehicle's functions (e.g.
Stop & Start).
Charging the battery using a
battery charger
For optimum service life of the battery, it is
essential to maintain an adequate state of
charge.
In some circumstances, it may be necessary to
charge the battery:
