9-22 Driving and Operating Automatic Transmission { 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. 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 9-19 and Driving Characteristics and Towing Tips on page 9-46. Make sure the shift lever is fully in P (Park) before starting the engine. The vehicle has an automatic transmission shift lock control system. With the ignition in ON/ RUN, fully apply the regular brake, then press the button on the back of the shift lever before shifting from P (Park). If you cannot shift out of P (Park), ease pressure on the shift lever, then push the shift lever all the way into P (Park) as you maintain brake application. Then press the shift lever button and move the shift lever into another gear. See Shifting out of Park on page 9-20.

Shift to R (Reverse) only after the vehicle is stopped. P (Park): This position locks the front wheels. It is the best position to use when starting the engine because the vehicle cannot move easily.
