pump until some resistance is
felt.
- Operate the starter motor while depressing the accelerator pedal
slightly until the engine starts.
If the engine fails to start at the first
attempt, wait 15 seconds before trying again.
If the engine fails to start after
several attempts, repeat the pro -

134 Access to the battery
The battery is located on the left hand side in the
engine compartment (see “ Engines “).
Emergency starting with a slave battery
A vehicle with a discharged battery can be started
with either a slave battery or the battery of another
vehicle.
A
Discharged battery
B Slave battery
C Earth point on broken down vehicle.
It is essential to proceed strictly following the sequence
indicated.
Check that the emergency battery is correctly charged
up (12 volts). If you are using the battery on another
vehicle, stop the engine of the assisting vehicle. The
two vehicles must not come into direct contact with
each other.
Connect the cables in the order indicated in the dia-
gram. Make sure that the clamps are properly secured
(risk of sparks).
Start the engine of the assisting vehicle. Let the engine
run for about a minute at a slightly accelerated speed.
Never apply a flame or create sparks close to the battery (explo-sive gas). The battery contains diluted sulphuric acid w hich is
highly corrosive.
If ever you are handling the battery, protect your eyes a nd face.
In the event of any contact with the skin, rinse immediatel y with
copious amounts of fresh water.
Advice
Replace it with a battery of the
same type (voltage, amp rating).
Do not touch the cable clamps
during the procedure.
Do not lean over the batteries.
Disconnect the cables in the
reverse order to connection,
ensuring that they do not touch
each other. Start the engine of the assisted vehicle.
Note:
For any repair necessitating a disconnection
of the battery, it is essential to wait three minutes
after switching off the ignition and to avoid any action
that could prevent the vehicle’s electrical circuit from
changing to standby mode (such as opening and clos-
ing doors, using the remote control etc.).

After the battery has been disconnected for a long period, it
may be necessary to re-initialise the following func-

- Anti-pinch and sequential operation on the electric window s.
- Parameters of the multifunction display (date, time, language , units of distance and temperature).
- Radio stations.
- Navigation reception.
- Synchronisation of remote control.
- Central locking.
Certain adjustments will be cancelled: it is necessary to make th em again.
WARNING: If disconnecting the battery, check that the colour navigation reader located in the glovebox
has finished its recording of information on switching off ignitio n: the warning lamp should have gone
out. Starting the engine for the first time after disconnecting and
connecting the battery:
- Turn the ignition key.
- Wait approx. one minute before actioning the starter, so a
s to allow the
electronic systems to reinitialise.

Use the special pliers A stowed on the cover close to the fuse-
boxes, this includes a compartment for replacement fuses.

To open the fuel flap, pull at its
notched edge. A label showing the
correct fuel quality will be found
on the inside of the flap (See “Fuel
quality”).
Locking filler cap
Turn the key a quarter turn to lock
and unlock the filler cap.
When refuelling, place the cap in
the support provided on the inside
of the filler flap.
If you have put in fuel that is wrong for your vehicle,
it is essential to have the tank drained before you start th e engine.
For petrol engines with catalytic converter, use of unlea
ded fuel is
obligatory
The filler neck has a narrower aperture to permit unleaded petrol only.
When you are filling your fuel tank, do not persist after the third cut-
off; this could cause your vehicle to malfunction.
UNLEADED PETROL DIESEL FUEL
Petrol engines are designed to run on RON 95 fuel; however , for better
vehicle performance (petrol engines), we recommend RON 98.
Fuel quality
A label on the inside of the fuel filler flap indicates the a
pproved fuel quality
type.
