Shifting Out of Park Automatic Transaxle

The automatic transaxle shift lock control system locks the shift lever in PARK when the ignition is in OFF. In addition, you have to fully apply your regular brakes 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 and 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 hold the brake pedal down but still cannot shift out of PARK (P), try this:

  1. Turn the ignition to ACC. There is no shift interlock in this key position.
  2. Apply and hold the brake until the end of Step 4.
  3. Shift the transaxle to NEUTRAL (N).
  4. Start the vehicle and then shift to the gear you want.
  5. Have the system fixed as soon as possible.
