How to Jump Start a Acura TSX Sport Wagon

1. Turn off power to electric devices such as audio and lights, switch off the engine, then open the hood.
2. Attach the first jumper cable to your vehicle's battery + terminal.
3. Attach the other end of the first cable to the booster battery + terminal, using a 12-volt booster battery only.
4. Attach the second jumper cable to the booster battery - terminal.
5. Attach the other end of the second cable to the engine mounting bolt and to no other part.
6. If using another vehicle, start its engine and raise its rpm slightly, then try starting your engine.
7. Once running, remove cables in reverse: your vehicle's ground, booster - terminal, your battery + terminal, then booster + terminal.

• If the engine turns over slowly, check that the jumper cables make good metal-to-metal contact.
• Battery performance degrades in cold conditions and may prevent the engine from starting.
• After the engine starts, have your vehicle inspected by a nearby service station or a dealer.
