Introduction Does your car have any of these issues?

Car fails to start

Battery light comes on

Cabin lights fail to turn on

Radio fails to turn on

Keyless entry remote transmitter fails to work

If you experience any of these car problems, then your car battery may have a problem. This set

of instructions will guide you on how to jump-start your car and inform you of what you should

do next, depending on whether your car starts or fails to start.

If your car starts, the battery could still have damage and you may need to replace it.

If you replace the faulty battery and your vehicle still fails to function properly, then you may

need to check your alternator and take further action.

How to Jump Your Car

Tools Needed:

Jumper cables

A car with a functional battery

Opening the Car Hood

1. Make sure the car engine is turned off and that the

keys leave the ignition.

2. Pull the interior hood latch, which is normally located

beneath the steering wheel on the driver’s side of the

car.

3. Open the car hood by releasing the latch under the

front of the hood.

4. Prop the car hood open with the hood lever.

5. Repeat steps 1-4 for the second car.

Attaching the Jumper Cables

1. Attach negative jumper cable to negative post on the

drained battery.

Helpful Hint: A flashlight may be necessary to locate

the exact position of the latch.

Helpful Hint: The black cable signifies a negative

charge, and the red cable signifies a positive charge.

The positive terminal will look red in color. Usually a

plastic cover with a positive symbol (+) protects the

terminal. The negative terminal will look black in color

or lack any identification.

2. Run the working car for 5-10 minutes.

3. Attempt to start the engine of the car with the drained

battery.

If the car starts, then the battery received a charge, but you may still have a bad battery and will

need to change it. Continue to the next page on how to change the battery.

If the car fails to start, then the battery failed to receive a charge, and the next step consists of

checking your alternator. Skip to page 13 for these instructions.
