How to Jump Start a Acura NSX

1. Turn off audio, lights and other electric devices, switch off the power system, then open the hood and remove the maintenance cover.
2. Slide the terminal cover back on your vehicle's 12-volt battery positive + terminal.
3. Connect the first jumper cable to your vehicle's 12-volt battery + terminal, then its other end 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 front frame only, not to any 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: your vehicle's ground, booster - terminal, your + terminal, then booster + terminal.

• If you use a booster battery, it must be a 12-volt one.
• If the engine turns over slowly, check that the jumper cables have good metal-to-metal contact.
• Have the vehicle inspected by a service station or an authorized Acura NSX dealer afterward.
