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 wish. See Shifting Out of Park (P) on page 2-39. REVERSE (R): Use this gear to back up. 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. To rock your vehicle back and forth to get out of snow, ice or sand without damaging your transaxle, see If Your Vehicle is Stuck in Sand, Mud, Ice or Snow on page 4-31. NEUTRAL (N): In this position, your engine does not connect with the wheels. To restart when you are already moving, use NEUTRAL (N) only. Also, use NEUTRAL (N) when your vehicle is being towed. {CAUTION: It is dangerous to get out of your vehicle if the shift lever is not fully in PARK (P) with the parking brake firmly set. Your vehicle can roll. Do not leave your vehicle when the engine is running unless you have to. If you have left the engine running, the vehicle can move suddenly. You or others could be injured. To be sure your vehicle will not move, even when you are on fairly level ground, always set your parking brake and move the shift lever to PARK (P). See Shifting Into Park (P) on page 2-38. If you are pulling a trailer, see Towing a Trailer on page 4-39. {CAUTION: Shifting into a drive gear while your engine is running at high speed is dangerous.
