134 Access to the battery

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.).
