A Guide To Jump Starting Your Car

A vehicle that will not start may have a discharged battery, but a jump-start is not the right answer to every no-start problem. Before connecting any equipment, check the owner's manual for your exact vehicle and decide whether roadside assistance is the safer option.

Start with the vehicle manual

Confirm whether jump-starting is permitted and locate the specified connection points. Some vehicles use remote jump terminals rather than connections directly on the battery. Follow the required voltage, equipment, connection sequence and disconnection sequence for that vehicle and the jump pack, if used.

Hybrid and electric vehicles have additional restrictions. Do not assume they can be used as a donor vehicle, and do not touch high-voltage components. If the manual is unavailable or the procedure is unclear, stop and arrange professional help.

Do not jump a damaged or potentially frozen battery

Do not attempt a jump-start if the battery is cracked, leaking, bulging or suspected to be frozen. Keep flames, cigarettes and sparks away from batteries. If you are stranded near moving traffic or cannot work safely, call roadside assistance rather than attempting the procedure there.

Know when to stop

Repeated attempts are not a diagnosis. Stop if you notice smoke, an unusual smell, damaged cables or behavior that does not match the instructions. A jump-start cannot repair a failed battery, charging-system problem or other fault that prevents starting.

Have the cause checked after a no-start event

If the vehicle starts, arrange battery and charging-system testing rather than assuming a short drive has solved the problem. Tell your advisor about slow cranking, dashboard warnings, lights left on, recent repairs and how long the vehicle sat unused.
