How to Jump Start a Honda Civic Sedan

1. Turn off audio, lights and other electric devices, switch the engine off, then open the hood.
2. Open the cover on the positive + terminal and clamp the first jumper cable to your battery's + terminal.
3. Attach the other end of the first cable to the booster battery's + terminal.
4. Clamp the second jumper cable to the booster battery's - terminal.
5. Attach the other end of the second cable to the stud bolt shown, and no other part.
6. Start the assisting vehicle's engine and raise its RPM slightly, then try starting your engine.
7. After your engine starts, remove the cables in reverse order: your ground, booster -, your battery +, booster +.

• Use a 12-volt booster battery only; if using a charger, select a voltage lower than 15-volt.
• If the engine turns over slowly, check that the cables make good metal-to-metal contact.
• Have the vehicle inspected by a nearby service station or a dealer after the jump start.
