Engine Exhaust CAUTION: (Continued) { CAUTION: Engine exhaust contains Carbon Monoxide (CO) which cannot be seen or smelled. Exposure to CO can cause unconsciousness and even death. Exhaust may enter the vehicle if: • The vehicle idles in areas with poor ventilation (parking garages, tunnels, deep snow that may block underbody airflow or tail pipes). • The exhaust smells or sounds strange or different. • The exhaust system leaks due to corrosion or damage. CAUTION: (Continued) • The vehicle's exhaust system has been modified, damaged or improperly repaired. • There are holes or openings in the vehicle body from damage or after-market modifications that are not completely sealed. If unusual fumes are detected or if it is suspected that exhaust is coming into the vehicle: • Drive it only with the windows completely down. • Have the vehicle repaired immediately. Never park the vehicle with the engine running in an enclosed area such as a garage or a building that has no fresh air ventilation. 2-36
