Remove all metal jewelery 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.
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.
Do not expose any battery to an open flame or spark, as the battery produces explosive, flammable gas.
Never jump start (boost), charge, or try to start a vehicle with a frozen battery. Doing so can result in an explosion.
Rotating parts of the engine can cause serious injury. Take extreme care when working near rotating parts of the engine.
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) or neutral is selected.
Suitable eye protection must be worn when working in the area of a battery.
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.
Make sure there is no physical contact between the donor and disabled vehicles, other than the jump leads.
Make sure that any battery or starting aid is a 12 volt device.
Disconnect the jump leads before operating any electrical equipment.
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.
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.
To connect the jump leads:
Refer to the donor vehicle's Owner's Handbook for the recommended positive boost terminal.
Refer to the donor vehicle's Owner's Handbook for the recommended negative boost terminal.
Check that all cables are clear of any moving components and that all four connections are secure.
If the vehicle fails to start, repeat step 5 for 20 minutes. If the vehicle still fails to start, seek qualified assistance.
Do not switch on any electrical circuits on the disabled vehicle until after the jump leads are removed.
