Engine "xhaust m Running Your Engine While You're Parked It's better notto park with the engine running. But if you ever have to, here are some things to know. I Engine exhaust can kill. It contains the gas or carbon monoxide (CO), which you can't see 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. 0 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. If you ever suspect exhaust is coming into your vehicle: 0 Drive it only with all the windows down to blow out any CO; and 0 Have your vehicle fixed immediately. 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 evenif the fan switch is at the highest setting. One place this can happen is a garage. Exhaust with CO can come in easily. NEVER park ina garage with the engine running. Another closed-in place can be blizzard. (See a "Blizzard" inthe Index.) -- -- ~ 1
