Automatic Transmission Operation The automatic transmission may have a shift lever located either on the steering column or on the console between the seats. { WARNING: It is dangerous to get out of the vehicle if the shift lever is not fully in P (Park) with the parking brake firmly set. The vehicle can roll. Do not leave the 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 the vehicle will not move, even when you are on fairly level ground, always set the parking brake and move the shift lever to P (Park). See Shifting Into Park on page 3 ‑ 29 . If you are pulling a trailer, see Towing a Trailer on page 5‑26. Make sure the shift lever is fully in P (Park) before starting the engine. The vehicle has an automatic transmission shift lock control system. You have to fully apply the regular brakes before you can shift from P (Park) while the ignition key is in ON/RUN. If you cannot shift out of P (Park), ease pressure on the shift lever. Push the shift lever all the way into P (Park) as you maintain brake application. Then move the shift lever into another gear. See Shifting Out of Park on page 3 ‑ 31 . There are several different positions for the shift lever. P (Park): This position locks the front wheels. It is the best position to use when you start the engine because the vehicle cannot move easily. 3-26
