Never jump-start a battery which has frozen, even after it has thawed WARNING!! If a battery has frozen it must be replaced. Please note that the described method of connecting the leads is meant for jump-starting your vehicle.
Preparations
Please read Link carefully before proceeding.
Apply the parking brake and move the selector lever to position P.
Switch off all electrical equipment and the ignition on both vehicles.
Connecting and disconnecting the jump leads
Connect one end of the red jump lead to the positive terminal -1- Fig. 2 of the discharged battery -A- Caution!.
Connect the other end of the red jump lead to the positive terminal -2- of the boosting battery -B-.
Connect one end of the black lead preferably to the earth point or alternatively to the negative battery terminal -3- on the vehicle providing assistance -B-.
Connect the other end of the black jump lead only to the earth point -4- of the jump-start connection on your vehicle -A-.
Position the jump leads in such a way that they cannot come into contact with any moving parts in the engine compartment.
Starting the engine
Start the engine of the vehicle with the boosting battery and let it run at idling speed.
Start the engine of the car with the discharged battery and wait two or three minutes until the engine is running smoothly.
If the engine fails to start: do not operate the starter for longer than 10 seconds. Wait for about 30 seconds and try again.
Switch on the blower and the rear window heating on the vehicle which has been jump-started in order to offset excessive voltage which may occur when disconnecting the leads. The headlights must be switched off!
Disconnect the leads in exactly the opposite sequence to that described in Link with the engines running. Make sure that the leads cannot come into contact with any moving parts in the engine compartment.
Close the cap on the positive terminal.
Switch off the blower and the rear window heating again.
Work on the battery should be carried out by a qualified workshop. However, if you do work on the battery yourself, always make sure that the battery clamps have good metal-to-metal contact with the battery terminals.
Please refer to WARNING!.
Note
The battery, which is protected by a metal cover, is located under the luggage compartment floor panel. To access the battery you require a certain degree of practical skill as well as special tools.
  • Connect the battery clamps so they have good metal-to-metal contact with the battery terminals.
  • The battery is vented to the outside to prevent gases entering the vehicle's interior.
