For 1990-2009 cars only

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 in RUN.

As you step on the brake pedal, while in PARK (P), you may hear a click from the solenoid of the system. This ensures that the system is operating properly. See Automatic Transaxle Operation .

If you cannot shift out of PARK (P), ease pressure on the shift lever by pushing the shift lever all the way into PARK (P) as you maintain brake application. Then try to move the shift lever into the gear you want. If you ever hold the brake pedal down but still can't shift out of PARK (P), try this:

  1. Turn the ignition key to OFF.
  2. Apply and hold the brake until the end of Step 4.
  3. Shift to NEUTRAL (N).
  4. Start the engine and then shift to the drive gear you want.
  5. Have the vehicle fixed as soon as you can.
