Shifting Out of Park Automatic Transmission

Your vehicle has an automatic transmission shift lock control system. You must fully apply your regular brakes before you can press the button on the shift lever to shift from PARK (P) while the ignition is ON. See Automatic Transmission Operation .

If you cannot shift out of PARK (P), ease pressure on the shift lever by pushing it all the way into PARK (P) while keeping the brake pedal down. Release the shift lever button. Then move the shift lever out of PARK (P), being sure to press the shift lever button.

If you ever hold the brake pedal down but still cannot shift out of PARK (P), try this:

  1. Turn the ignition to LOCK to remove the key.
  2. Remove the front console rubber insert, located in front of the shift lever, by lifting upwards.
  3. Remove the screw slightly to the right of the front center.
  4. Open the console storage compartment and pry the console cover assembly from the console. The cover is attached in six places.
  5. Insert a tool into the opening in front of the shift lever and move the yellow release lever forward.
  6. Press the button on the shift lever to move lever out of park.
  7. Replace the console cap.
  8. Have the vehicle fixed as soon as possible.
