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, 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 the hands thoroughly after handling the battery. Excessive exposure to lead may cause long-term illness.

WARNING

Do not expose any battery to an open flame or spark, as the battery produces explosive, flammable gas. An open flame or sparks may cause a fire or explosion, resulting in serious injury or death.

WARNING

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

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. Failing to do so may result in unexpected movement of the vehicle, potentially causing death or serious injury.

WARNING

Suitable eye protection must be worn when working in the area of a battery. The battery contains acid, which, when coming into contact with eyes, may cause serious injury.

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. Ignition sources may cause explosions, potentially resulting in serious injury or death.

WARNING

Make sure there is no physical contact between the donor and disabled vehicles, other than the jump leads. The body of the vehicles can conduct electricity, which may cause an electric shock.

WARNING

Do not disconnect the discharged battery. Disconnectin a discharged battery may cause an electric shock, resulting in injury.

CAUTION

Make sure that any battery or starting aid is a 12V device. Non-12V devices may cause damage to the vehicle.

CAUTION

Disconnect the jump leads before operating any electrical equipment. Failing to do so may cause damage to the vehicle’s systems.

NOTES

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

Before connecting and disconnecting the jump leads, open the bonnet and remove the under-bonnet covers. Locate the 12V battery. See UNDER-BONNET COVERS REMOVAL.

The following procedure should be used to connect and disconnect the jump leads:

  1. Connect one end of the positive (red) jump lead to the positive boost terminal on the donor vehicle.

    NOTES

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

  2. Connect the other end of the positive (red) jump lead to the positive battery terminal on the disabled vehicle.

  3. Connect one end of the negative (black) jump lead to the negative boost terminal on the donor vehicle.

    NOTES

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

  4. Connect the other end of the negative (black) jump lead to the negative battery terminal on the disabled vehicle.

    NOTES

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

  5. If the donor vehicle has an internal combustion engine, start the engine and allow it to idle for a few minutes. If the donor vehicle is an Electric Vehicle (EV), start the electrical system. With the electrical system on for a few minutes, charge the vehicle's 12V battery from the main propulsion battery.

  6. Press the START/STOP button once to start the electrical system of the disabled vehicle. See ENABLING THE VEHICLE'S ELECTRICAL SYSTEM.

    NOTES

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

  7. Allow the donor vehicle to charge the disabled vehicle for a few minutes.

  8. Switch off the donor vehicle.

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

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

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

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

Refit the under-bonnet covers. See UNDER-BONNET COVERS REFITTING.

Close the bonnet.
