Automatic Transmission Operation There are several different positions for your shift lever. Push in the button on top of the shift lever when shifting into position. CAUTION: (Continued) 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) (Automatic Transmission) on page 2-24. If you are pulling a trailer, see Towing a Trailer on page 4-34. Ensure the shift lever is fully in PARK (P) before starting the engine. Your vehicle has an automatic transmission shift lock control system. You must have your foot on the regular brakes before you can shift from PARK (P) when the ignition key is in ON. The vehicle will not shift from PARK (P) if the button is pressed before the brake is applied. If you cannot shift out of PARK (P), ease pressure on the shift lever, push the shift lever all the way into PARK (P), and release the shift lever button as you maintain brake application. Then press the shift lever button and move the shift lever into the desired gear. See Shifting Out of Park (P) (Automatic Transmission) on page 2-26. 2-19 PARK (P): The engine can be started in this position. This position prevents the rear wheels from turning and so should be selected, together with the parking brake, when leaving the vehicle. {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. CAUTION: (Continued)
