GM Service Manual Online
For 1990-2009 cars only

This vehicle is equipped with an electronic shift lock release system. The shift lock release is designed to:

    • Prevent ignition key removal unless the shift lever is in P (Park) with the shift lever button fully released, and
    • Prevent movement of the shift lever out of P (Park), unless the ignition is in ON/RUN or ACC/ACCESSORY and the regular brake pedal is applied.

The shift lock release is always functional except in the case of an uncharged or low voltage (less than 9 volt) battery.

If the vehicle has an uncharged battery or a battery with low voltage, try charging or jump starting the battery. See Jump Startingfor more information.

To shift out of P (Park) use the following:

  1. Apply the brake pedal.
  2. Move the shift lever to the desired position.

If you still are unable to shift out of P (Park):

  1. Ease the pressure on the shift lever.
  2. While holding down the brake pedal, press the shift lever all the way into P (Park).
  3. Move the shift lever to the desired position.

If you are still having a problem shifting, then have the vehicle serviced soon.
