{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 2-34. If you are pulling a trailer, see Towing a Trailer on page 4-29. Make sure the shift lever is fully in PARK (P) before starting the engine. The vehicle has an automatic transmission shift lock control system. You must fully apply your regular brakes first and then press the shift lever button, located on the front of the shift lever, before you can shift from PARK (P) when the ignition key is in RUN. If the vehicle cannot be shifted 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 press the shift lever button and move the shift lever into another gear. See Shifting Out of PARK (P) on page 2-35. REVERSE (R): Use this gear to back up. Notice: Shifting to REVERSE (R) while your vehicle is moving forward could damage the transmission. The repairs would not be covered by your warranty. Shift to REVERSE (R) only after your vehicle is stopped. To rock the vehicle back and forth to get out of snow, ice or sand without damaging the transmission, see If Your Vehicle is Stuck in Sand, Mud, Ice, or Snow on page 4-21. 2-29
