Your vehicle gets rusty underneath. Your vehicle wasdamaged in a collision. Your vehicle was damaged when driving over or high points on the road over road debris. Repairs weren't done correctly. Your vehicle or exhaust system had been modified improperly. If you ever suspectexhaust is coming into your vehicle: Drive it only with allthe windows down to blow out any CO; and Have your vehicle fixed immediately. Idling the engine withthe climate control system off could allowdangerous exhaust into your vehicle (seethe 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 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 placecan be a blizzard. (See "Blizzard" inthe Index.) 1 -- -- I 2-29
