Shifting Into Park (P) {CAUTION: It can be 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. 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, use the steps that follow. With four-wheel drive, your vehicle will be free to roll - even if your shift lever is in PARK (P) - if your transfer case is in NEUTRAL. So, be sure the transfer case is in a drive gear - not in NEUTRAL. See Four-Wheel Drive on page 122. Always put the shift lever fully in PARK (P) with the parking brake firmly set. If you are pulling a trailer, see Towing a Trailer on page 362. To shift into PARK (P), do the following: 1. Hold the brake pedal down with your foot and set the parking brake. 2. Move the shift lever into PARK (P) by pressing the button on the side of the shift lever and pushing the lever all the way toward the front of the vehicle. 3. Turn the ignition key to LOCK. 4. Remove the key and take it with you. You know your vehicle is in PARK (P) if the key can be removed from the ignition. 127
