How to Jump Start a Acura MDX

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 + terminal.
4. Connect the other end of the first cable to the booster battery + terminal.
5. Connect the second jumper cable to the booster battery - terminal.
6. Connect the other end of the second cable to the ground bolt shown, and nowhere else.
7. Start the assisting vehicle's engine and raise its RPM slightly, then try starting your engine.
8. After your engine starts, remove the cables in reverse order: your ground, booster -, your battery +, then 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.
