CONNECTING JUMP LEADS

WARNING

Remove all metal jewellery before working on, or near, a battery or boost terminals. Never allow metal objects or vehicle components to come into contact with the battery or boost terminals. Metal objects can cause sparks or short circuits, potentially resulting in an explosion.

WARNING

Do not allow the battery posts or terminals to come into contact with skin. Battery posts and terminals contain lead and lead compounds, which are toxic. Always wash hands thoroughly after handling the battery.

WARNING

Do not expose any battery to an open flame or spark, as the battery produces explosive, flammable gas.

WARNING

Do not connect the jump leads to any battery terminal on the vehicle. Doing so can cause a spark, which can result in an explosion. Doing so will also result in damage to the charging system.

WARNING

Never jump start (boost), charge, or try to start a vehicle with a frozen battery. Doing so can result in an explosion.

WARNING

Rotating parts of the engine can cause serious injury. Take extreme care when working near rotating parts of the engine.

WARNING

Before attempting to start the vehicle, make sure that the Electric Parking Brake (EPB) is applied, or suitably chock the wheels. Make sure that Park (P) is selected. Failure to do so may result in accidents causing serious injury or death.

WARNING

Suitable eye protection must be worn when working in the area of a battery. Battery acid can cause serious injury to eyes.

WARNING

During normal use, batteries emit explosive gas sufficient to cause severe explosions and capable of causing serious injury. Keep sparks and open flames away from the battery.

CAUTION

Make sure there is no physical contact between the donor and disabled vehicles, other than the jump leads. Failure to do so may cause damage to the vehicle.

CAUTION

Make sure that any battery or starting aid is a 12-volt device. Unapproved devices can cause damage to the vehicle.

CAUTION

Disconnect the jump leads before operating any electrical equipment. Failure to do so may cause damage to the vehicle.

CAUTION

Make sure the jump leads being used are of high quality, in good condition and are rated to the engine capacity of both vehicles. Incorrectly rated jump leads may not supply sufficient power to the disabled vehicle's battery and may overheat when attempting to start the vehicle.

NOTES

Before connecting the jump leads to the disabled vehicle's boost point terminals, make sure the donor vehicle's boost point connections are correct. Also make sure that all electrical equipment has been switched off.

  1. Disabled vehicle.

  2. Donor vehicle.

To connect the jump leads:

  1. Connect the positive (red) jump lead to the recommended positive (+) boost point terminal on the donor vehicle.

    NOTES

    Refer to the donor vehicle's Owner's Handbook for the recommended positive boost terminal.

  2. Connect the other end of the positive (red) jump lead to the positive (+) boost point terminal on the disabled vehicle, as illustrated.

  3. Connect the negative (black) jump lead to the recommended negative (-) boost point terminal on the donor vehicle.

    NOTES

    Refer to the donor vehicle's Owner's Handbook for the recommended negative boost terminal.

  4. Connect the other end of the negative (black) jump lead to the negative (-) boost point terminal on the disabled vehicle, as illustrated.

    NOTES

    Check that all cables are clear of any moving components. Make sure that all four connections are secure.

  5. Start the engine of the donor vehicle. Allow the engine to idle for a few minutes.

  6. Start the engine on the disabled vehicle.

    NOTES

    Do not switch on any electrical circuits on the disabled vehicle until after the jump leads are removed.

  7. Allow both vehicles to idle for 2 minutes.

  8. Switch off the donor vehicle.

  9. Disconnect the negative (black) jump lead from the previously disabled vehicle.

  10. Disconnect the negative (black) jump lead from the donor vehicle.

  11. Disconnect the positive (red) jump lead from the previously disabled vehicle.

  12. Disconnect the positive (red) jump lead from the donor vehicle.
