If this condition occurs before you have the opportunity to have the inspection/correction made at your GM dealer, try the following:

1. Leave key in the ON position for five (5) minutes.

2. Then start the vehicle in the normal manner, with your foot on the brake pedal, try to pull the shift lever out of the park position using normal effort.

3. Repeat steps 1 and 2 up to two (2) times, if necessary waiting the five (5) minutes each time.
