How to Jump Start a Acura TL

1. Turn off all electrical accessories, put the transmission in neutral (manual) or Park (automatic), and set the parking brake.
2. Pull up the battery terminal cover to remove it.
3. Connect one jumper cable to the positive (+) terminal on your battery and the other end to the positive (+) terminal on the booster battery.
4. Connect the second jumper cable to the negative (−) terminal on the booster battery and the other end to the engine hanger, not any other engine part.
5. If the booster battery is in another vehicle, have an assistant start it and run it at a fast idle.
6. Start your vehicle; if the starter still turns slowly, check the cables for good metal-to-metal contact.
7. Once running, disconnect the negative cable from your vehicle, then the booster battery, then the positive cable from your vehicle, then the booster battery.
8. Install the battery terminal cover.

• Do not jump start if the electrolyte looks slushy or icy in very cold weather.
• Keep sparks, open flames, and smoking materials away from the battery, which can explode.
• Keep cable ends away from each other and vehicle metal until all are disconnected.
