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 press the shift lever button and then move the shift lever into another gear. See Shifting Out of Park (P) (Automatic Transaxle) on page 123. REVERSE (R): Use this gear to back up.
