For 1990-2009 cars only

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

If you cannot shift out of PARK (P), ease 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 have the console shift lever, press the button first). If you ever hold the brake pedal down but still can't shift out of PARK (P), try this:

  1. Turn the key to OFF.
  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. Take your vehicle to an authorized service center as soon as you can.
