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.
This terminal has a quick-release clamp.
(-) Negative terminal.
As the battery's negative terminal is not
accessible, a remote earth point is placed on the
structure of the front right wing.
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 earth point C .
► 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.
► Wait 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 functionalities.
