Engine Exhaust Running the Vehicle While Parked {CAUTION: Engine exhaust can kill. It contains the gas carbon monoxide (CO), which you cannot see or smell. It can cause unconsciousness and death. You might have exhaust coming in if: • The exhaust system sounds strange or different. • Your vehicle gets rusty underneath. • Your vehicle was damaged in a collision. • Your vehicle was damaged when driving over high points on the road or over road debris. • Repairs were not done correctly. • Your vehicle or the exhaust system has been modified improperly. If you ever suspect exhaust is coming into your vehicle: • Drive it only with all the windows down to blow out any CO; and • Have your vehicle fixed immediately. It is better not to park with the engine running. But if you ever have to, here are some things to know. {CAUTION: Idling the engine with the climate control system off could allow dangerous exhaust into your vehicle. See the earlier caution under Engine Exhaust on page 2-37. Also, idling in a closed-in place can let deadly carbon monoxide (CO) into your vehicle even if the climate control fan is at the highest setting. One place this can happen is 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 Winter Driving on page 4-17. 2-37
