Engine Exhaust Running Your Engine While You're Parked It's better not to park with the engine running. But if you ever have to, here are some things to know. Engine exhaust can kill. It contains the gas carbon monoxide (CO),which you can't see or smell. It can cause unconsciousness and death. You might have exhaust coming in if: 0 Your exhaust system sounds strange or different. 0 Your vehicle gets rusty underneath. Your vehicle was damaged in a collision. 0 Your vehicle was damaged when driving over high points on the road or over road debris. 0 Repairs weren't done correctly. 0 Your vehicle or exhaust system had been modified improperly. I f you ever suspect exhaust is coming into your vehicle: Drive it only with all thewindows down to blow out anyCO; and 0 Have your vehicle fixed immediately. r Idling the engine with the climate control system off could allow dangerous exhaust into your vehicle (see the earlier Caution under "Engine Exhaust"). Also, idling in a closed-in place can let deadly carbon monoxide (CO)into your vehicle even if the fan switch isat the highest setting. One place thiscan happen is a garage. Exhaustwith 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 the Index.) -- 2-25
