Make sure the shift lever is fully in PARK (P) before starting the engine. The vehicle has an electronic shift lock release system. You must fully apply the regular brakes before shifting from PARK (P) when the ignition is in RUN. If you cannot shift out of PARK (P), ease pressure on the shift lever by pushing it all the way into PARK (P) as you maintain brake application. Then move the shift lever into another gear. See Shifting Out of Park (P) on page 120 Notice: Shifting to REVERSE (R) while your vehicle is moving forward could damage the transaxle. The repairs would not be covered by your warranty. Shift to REVERSE (R) only after your vehicle is stopped. REVERSE (R): Use this gear to back up. To rock the vehicle back and forth in order to get it out of snow, ice, or sand without damaging the transaxle, see If Your Vehicle is Stuck in Sand, Mud, Ice, or Snow on page 318. NEUTRAL (N): In this position, the engine does not connect with the wheels. To restart when you are already moving, use NEUTRAL (N) only.
