How to Jump Start a Honda Civic Coupe

1. Turn off power to electric devices such as audio and lights, switch off the engine, then open the hood.
2. Connect the first jumper cable to your vehicle's battery + terminal.
3. Connect the other end of the first cable to the booster battery + terminal.
4. Connect the second jumper cable to the booster battery - terminal.
5. After the engine starts, remove the cables in reverse order: your vehicle's ground first, then booster -, your battery +, and booster +.

• If using an automotive battery charger, select a charging voltage lower than 15-volt.
• Have your vehicle inspected by a nearby service station or a dealer after the engine starts.
