Automatic Transmission Operation The automatic transmission shift lever is located on the center console between the front seats. PARK (P): This position locks the rear wheels. It's the best position to use when you start the engine because your vehicle can't move easily. 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. Don't 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 won't move, even when you're on fairly level ground, always set your parking brake and move the shift lever to PARK (P). See "Shifting Into PARK (P)" in the Index. If you're pulling a trailer, see "Towing a Trailer" in the Index. There are several different positions for the shift lever. 2-30
