Automatic Transmission Shift Lock

The vehicle has an automatic transmission shift lock control system. The shift lock control system is designed to:

. Prevent ignition key removal unless the shift lever is in P (Park).

. Prevent movement of the shift lever out of P (Park), unless the ignition is in ON/RUN and the brake pedal is applied.

The shift lock 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 Starting .

If the shift lever cannot be moved out of P (Park):

1. Apply and maintain the regular brakes.

2. Turn the ignition to the ON/RUN position. See Ignition Positions (Key Access)  or Ignition Positions (Keyless Access)  for more information.

3. Let up on the shift lever and make sure the shift lever is pushed all the way into P (Park).

4. Press the shift lever button.

5. Move the shift lever into the desired gear.

If you still cannot move the shift lever from P (Park), consult your dealer or a professional towing service.
