GM Service Manual Online
For 1990-2009 cars only

If the battery has run down, try to use another vehicle and some jumper cables to start your vehicle. Be sure to use the following steps to do it safely.

Caution: Batteries can hurt you. They can be dangerous because:

   • They contain acid that can burn you.
   • They contain gas that can explode or ignite.
   • They contain enough electricity to burn you.
If you do not follow these steps exactly, some or all of these things can hurt you.

Notice: Ignoring these steps could result in costly damage to the vehicle that would not be covered by the warranty.

Trying to start the vehicle by pushing or pulling it will not work, and it could damage the vehicle.

The jump start positive (A) and negative posts (B) are located in the engine compartment on the driver side of the vehicle.

These posts are used instead of a direct connection to the battery.

The positive jump start connection is covered by a red cap. Remove to expose the terminal.

  1. Check the other vehicle. It must have a 12-volt battery with a negative ground system.
  2. Notice: If the other vehicle's system is not a 12-volt system with a negative ground, both vehicles can be damaged. Only use vehicles with 12-volt systems with negative grounds to jump start your vehicle.

  3. Position the two vehicles so that they are not touching.
  4. Set the parking brake firmly and put the shift lever in P (Park). See Shifting Into Park .
  5. Notice: If you leave the radio or other accessories on during the jump starting procedure, they could be damaged. The repairs would not be covered by the warranty. Always turn off the radio and other accessories when jump starting the vehicle.

  6. Turn the ignition to LOCK/OFF and switch off all lights and accessories in both vehicles, except the hazard warning flashers if needed.
  7. Caution: An electric fan can start up even when the engine is not running and can injure you. Keep hands, clothing and tools away from any underhood electric fan.

    Caution: Using a match near a battery can cause battery gas to explode. People have been hurt doing this, and some have been blinded. Use a flashlight if you need more light.

    Be sure the battery has enough water. You do not need to add water to the battery installed in your new vehicle. But if a battery has filler caps, be sure the right amount of fluid is there. If it is low, add water to take care of that first. If you don't, explosive gas could be present.

    Battery fluid contains acid that can burn you. Do not get it on you. If you accidentally get it in your eyes or on your skin, flush the place with water and get medical help immediately.

    Caution: Fans or other moving engine parts can injure you badly. Keep your hands away from moving parts once the engine is running.

  8. Connect one end of the red positive (+) cable to the jump start positive (+) post (A).
  9. Connect the other end of the red positive (+) cable to the positive (+) terminal of the good battery (B).
  10. Connect one end of the black negative (-) cable to the negative (-) terminal of the good battery (C).
  11. Connect the other end of the black negative (-) cable to the negative (-) post (D).
  12. Start the engine in the vehicle with the good battery and run the engine at idle speed for at least four minutes.
  13. Try to start the vehicle that had the dead battery. If it will not start after a few tries, it probably needs service.

Notice: If the jumper cables are connected or removed in the wrong order, electrical shorting may occur and damage the vehicle. The repairs would not be covered by the vehicle warranty. Always connect and remove the jumper cables in the correct order, making sure that the cables do not touch each other or other metal.
