Your vehicle has an automatic transaxle shift lock control system. You have to fully apply your regular brakes before you can shift from PARK (P) when the ignition is ON. See Automatic Transaxle Operation .

The shift lock control system is designed to do the following:

    • Prevent the ignition key from being removed unless the shift lever is in PARK (P), and
    • prevent movement of the console shift lever (DTS only) out of PARK (P) unless the ignition is in a position other than OFF.

The shift lock control system is always functional except in the case of a dead battery or low voltage (less than 9 V) battery.

If you cannot shift out of PARK (P), ease the pressure on the shift lever. Push the shift lever all the way into PARK (P) as you maintain brake application. Then move the shift lever into the gear you want.

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

  1. Turn the ignition key to ACCESSORY. Open and close the driver's door to turn off the RAP feature.
  2. Apply and hold the brake until the end of Step 4.
  3. Shift to NEUTRAL (N).
  4. Start the vehicle and then shift to the drive gear you want.
  5. Have the vehicle fixed as soon as you can.
