GM Service Manual Online
For 1990-2009 cars only

Move your shift lever to PARK (P) or NEUTRAL (N). Your engine won't start in any other position - that's a safety feature. To restart while you're already moving, use NEUTRAL (N) only.

Notice: Shifting into P (Park) with the vehicle moving could damage the transmission. Shift into P (Park) only when your vehicle is stopped.

Shift Lock Release

This vehicle is equipped with an electric shift lock release system. The shift lock release is designed to do the following:

    • Prevent ignition key removal unless the shift lever is in PARK (P) with the shift lever button fully released.
    • Prevent movement of the shift lever out of PARK (P) unless the ignition is in a position other than OFF or LOCK. The shift lock release is always functional except in the case of a dead or low voltage (less than 9 V) battery.

If your vehicle has a dead battery or a battery with low voltage, there is an override access slot that will allow you to override the shift lock release.


Object Number: 822855  Size: A3

The override access slot is located on the upper right side of the console shift panel.

To use the slot, do the following:

  1. Verify that the shift lever is in PARK (P) and that the shift lever button is fully released.
  2. Locate the override access slot on the upper right side of the shift panel.
  3. Remove the override access slot cap.
  4. Insert a key into the access slot, press in and hold.
  5. Press the shift lever button in and hold.
  6. Remove the key from the slot.
  7. Pull the shift lever into the desired gear position.
  8. Reinstall the override access slot cap.

You will not be able to remove the key from the ignition unless the shift lever is in the PARK (P) position with the shift lever button fully released.

Starting Your 3100  V6 Engine

  1. With your foot off the accelerator pedal, turn your ignition key to START. When the engine starts, let go of the key. The idle speed will go down as your engine gets warm.
  2. Notice: Holding the key in START for longer than 15 seconds at a time will cause the battery to be drained much sooner. And the excessive heat can damage the starter motor. Wait about 15 seconds between each try to help avoid draining the battery or damaging the starter.

  3. If your engine won't start (or starts but then stops), it could be flooded with too much gasoline. Try pushing your accelerator pedal all the way to the floor and holding it there as you hold the key in START for not more than 15 seconds at a time. This clears the extra gasoline from the engine.

Notice: The engine is designed to work with the electronics in the vehicle. If electrical parts or accessories are added, you could change the way the engine operates. Before adding electrical equipment, check with your dealer/retailer. If you do not, the engine might not perform properly. Any resulting damage would not be covered by the vehicle warranty.

Starting Your 3800 Series II V6 Engine

  1. With your foot off the accelerator pedal, turn your ignition key to START. When the engine starts, let go of the key. The idle speed will go down as your engine gets warm.
  2. Notice: Holding the key in START for longer than 15 seconds at a time will cause the battery to be drained much sooner. And the excessive heat can damage the starter motor. Wait about 15 seconds between each try to help avoid draining the battery or damaging the starter.

  3. If it doesn't start within 10 seconds, hold your key in START for about 10 seconds at a time until your engine starts. Wait about 15 seconds between each try.
  4. If your engine still won't start (or starts but then stops), it could be flooded with too much gasoline. Try pushing your accelerator pedal all the way to the floor and holding it there as you hold the key in START for about three seconds. If the vehicle starts briefly but then stops again, do the same thing. This time keep the pedal down for five or six seconds to clear the extra gasoline from the engine. After waiting about 15 seconds, repeat the normal starting procedure.

Notice: The engine is designed to work with the electronics in the vehicle. If electrical parts or accessories are added, you could change the way the engine operates. Before adding electrical equipment, check with your dealer/retailer. If you do not, the engine might not perform properly. Any resulting damage would not be covered by the vehicle warranty.
