Starting the engine with an assisting battery

If the battery is discharged, it is possible to use either a separate
emergency battery or a battery on another vehicle.
A. Dischargedbattery (Under the bonnet).
B. Assisting battery.

Check that the assisting battery has sufﬁ cient voltage (12 V).
If you use the battery on another vehicle, stop the engine on the
latter. The two vehicles must not come into direct contact with
each other.
Connect the cables according to the order indicated in the

order

diagram. Check that the leads are well secured (risk of sparks).
Start the engine of the assisting vehicle. Let the engine run for
around 1 minute at a slightly accelerated idle.
Operate the starter on the vehicle being assisted.
It is essential to follow the indicated sequence correctly.

Never approach with a ﬂ ame or create sparks in the vicinity

of the battery (explosive gas).
The battery contains dilute sulphuric acid which is highly
corrosive.
When handling batteries, always protect your face and
especially your eyes.
In the event of any contact with the skin, rinse immediately
with copious amounts of fresh water.

Advice

Do not touch the leads during
the operation.

Do not lean over the batteries.
Disconnect the cables in reverse
order, making sure they do not
touch together.

Locking ﬁ ller cap

Turn the key a quarter turn to lock

and unlock the ﬁ ller cap.
When refuelling, place the cap in

the support provided on the inside

of the ﬁ ller ﬂ ap.
For a petrol engine with a cata-

lytic converter, unleaded fuel is

compulsory.

The ﬁ ller neck is narrower to

ensure that only unleaded petrol

can be put in.

When you are seeking to ﬁ ll your tank, do not persist after the third

cut-off ; that could cause your vehicle to malfunction.

Fuel tank capacity (in litres): Approx. 41.

If you should put in fuel that is not suitable for your vehicle's

engine type, it is imperative to have the tank drained before

you start the engine again.

FUEL QUALITY

A label inside the ﬁ ller ﬂ ap tells you which type of fuel to use.

UNLEADED PETROL

DIESEL FUEL

The petrol engines are designed to run on RON 95.
However, for better performance (petrol engine), we recommend RON 98.
