How to Jump Start a Honda Accord

1. Turn off power to electric devices such as audio and lights, switch off the engine, then open the hood.
2. Open the cover on the positive terminal of your vehicle's battery.
3. Connect the first jumper cable to your vehicle's battery positive terminal, then connect its other end to the booster battery positive terminal.
4. Connect the second jumper cable to the booster battery negative terminal.
5. Connect the other end of the second jumper cable to the stud bolt (a), and to no other part.
6. Start the assisting vehicle's engine and raise its RPM slightly, then try to start your engine.
7. After your engine starts, remove the cables in reverse order, beginning with the one on your vehicle's ground.

• Use a 12-volt booster battery only.
• If the engine turns over slowly, check that the jumper cables have good metal-to-metal contact.
• A 12-volt battery can explode if the procedure is not followed, so keep sparks, flames and smoking materials away.
