Leaving Your Vehicle With the Engine Running Move the lever up as far as it will go. 3. Move the ignition key to the LOCK position. 4. Remove the key and take it with you. If you can leave your vehicle with the ignition key in your hand, your vehicle is in PARK (P). It can be dangerous to leave your vehicle with the engine running. Your vehicle could move suddenly if the shiftlever is not fully in PARK (P) with the parking brake firmly set. And, if you leave the vehicle with the engine running, it could overheat and even catch fire. You or others could be injured. Don't leaveyour vehicle with the engine running unless you have to. If you have to leave your vehicle with the engine running, be sure your vehicle is in PARK (P) and your parking brake is firmly set before you leave it. After you've moved the shift lever into the PARK (P) position, hold the regular brake pedal down. Then, see if you can move the shift lever away from PARK (P) without first pulling it toward you. If you can, it means that the shift lever wasn't fully locked into PARK (P).
