How to Jump Start a Honda Odyssey

1. Turn off audio, lights and other electric devices, 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 that cable 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, and nowhere else.
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: engine bolt, booster -, your battery +, booster +.

• Use a 12-volt booster battery only.
• If the engine turns over slowly, check that the jumper cables have good metal-to-metal contact.
• Have your vehicle inspected by a nearby service station or a dealer after the engine starts.
