First of all, read the “Vehicle maintenance” section for the steps to be taken to avoid the battery running down and to ensure it has a long life.
IF THE BATTERY IS FLAT
Charging should be slow at a low amp rating for 24 hours. Charging for a longer time may damage the battery.
Proceed as follows:
1) Disconnect the electrical system from the battery terminals.
IMPORTANT
Where relevant, switch the electronic alarm off with the remote control.
2) Connect the charger cables to the battery terminals.
3) Turn on the charger.
4) When you have finished, turn the charger off before disconnecting the battery.
5) Reconnect the cables to the battery terminals. Make sure the polarity is correct.
The liquid in the battery is poisonous and corrosive.
Do not let it touch the skin or eyes. Recharging the battery should be done in a well ventilated area away from naked flames or possible sources of sparks: explosion and fire risk.
JUMP STARTING
See “Jump starting”, in this chapter.
Do not attempt to recharge a frozen battery.
Thaw it first otherwise it could explode. If the battery froze, make sure that the internal elements are not broken (short-circuit risk) and that the casing is not cracked (risk of spilling the poisonous and corrosive fluid).

Under no circumstances should a battery charger be used to start the engine:
it could damage the electronic systems and in particular the ignition and injection control units.
