Running Your Engine While You're Parked (Automatic Transmission) It's better not topark with the engine running. But if ever have to, here are some things to know. I A CAUTION: It can be dangerous to get out of your vehicle if the shiftlever is not fully in PARK with the (P) parking brakefirmly set. Your vehiclecan roll. Don't leave your vehicle whenthe engineis running unless you have to. If you've left the engine running, the vehicle can move suddenly. You or otherscould be injured. To be sure your vehicle won't move, even when you're fairly on level ground, always set your parkingbrake and move the shiftlever to PARK(P). If you have four-wheel drive with a manual transfer case shift lever and your transfer case is in NEUTRAL (N), your vehicle will be free to roll, even if your shift lever is in PARK (P). So, be sure the transfer case is in a drive gear -- not in NEUTRAL (N). Always set your parking brake. Follow the proper steps to be sure your vehicle won't move. See "Shifting Into PARK (P)" in the Index. If you're pulling a trailer, see "Towing a Trailer" in the Index. A CAUTION: Idling the engine with the air system control off could allow dangerous exhaust into your vehicle (seethe earlierCaution under "Engine Exhaust"). Also, idling in a closed-in place can let deadly carbon monoxide (CO) into your vehicle evenif the fan switch at the highest setting. One place is this can happenis a garage. Exhaust with CO can come in easily. NEVER park in a garage with the engine running. Another closed-in place can be a blizzard. (See "Blizzard" in theIndex.) -- 9- 2-35
