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 on broken-down vehicle
(under the bonnet).
B Slave battery
C Earth point on broken-down vehicle.
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.
Never apply a flame or create sparks close to the battery (explosive gas).
The battery contains diluted sulphuric acid which i s 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.
For
any battery replacement, contact a CITROËN dealer.
Advice
Do not touch the cable clamps
during the procedure.
Do not lean over the batteries.
Disconnect the cables in the re-
verse order to connection, ensuring
that they do not touch each other.
Connect the cables in the
order indicated in the diagram. Make sure that the clamps are properl y secured
(risk of sparks).
Start the engine of the assisting vehicle. Let the engine run for about a minute at a slightly accelerated speed.
Start the engine of the assisted vehicle.
Note : For any operation necessitating a disconnection of the batte ry, you should wait three minutes after switch-
ing off the ignition, without taking any action which w ould prevent the vehicle’s electrical circuit from going to sleep
(such as operating the doors and tailgate or the remote control , etc.).
After a disconnection and reconnection of the battery, when you switch on the ignition, wait for approximately one
minute before operating the starter motor in order to allow t he electronic systems to reinitialise. Following a pro-
longed disconnection of the battery, it may be necessary to rei nitialise the parameters of the multifunction display
(date, time, language, units of distance and of temperature ).
