How to Jump Start a Honda Civic Hatchback

1. Turn off electric devices such as audio and lights, switch off the engine, and open the hood.
2. Open the cover on your vehicle's battery positive + terminal.
3. Connect the first jumper cable to your vehicle's battery + terminal, then its other end to the booster battery + terminal.
4. Connect the second jumper cable to the booster battery - terminal.
5. Connect the other end of the second cable to the engine mounting bolt shown, and nowhere else.
6. Start the assisting vehicle's engine and raise its rpm slightly, then try starting your engine.

• Use a 12-volt booster battery only.
• If the engine turns over slowly, check that the cables make good metal-to-metal contact.
• Remove cables in reverse order: your ground, booster -, your battery +, booster +.
