Engine Exhaust Running Your Engine While You're Parked It's better not to park with the engine running. But if you ever haveto, here are some things to know. /r\ CAUTION: Engine exhaust cankill. It contains the gas carbon monoxide (CO), which you can't seeor smell. It can causeunconsciousness and death. You might have exhaust coming in if: Your 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 over road debris. or Repairs weren't done correctly. Your vehicle or exhaust system had been modified improperly. If you ever suspect exhaust is coming into your vehicle: Drive it only with all the windows downto blow out anyCO; and Have your vehicle fixed immediately. A CAUTION: Idling the engine with the air system control off could allow dangerous exhaust into your vehicle (see the earlier Caution under "Engine Exhaust"). Also, idling in a closed-in place can letdeadly carbon monoxide (CO)into yourvehicle evenif the fanswitch is at thehighest setting. Oneplace this can happen is a garage.
