Driving and Operating Evaporation Pump The vehicle is equipped with a vacuum pump for the fuel evaporation system. This pump performs a fuel evaporation leakage test approximately five hours after the engine is turned off. You may hear a sound coming from underneath the rear cargo compartment for several minutes. The noise is normal and does not signify a malfunction. See your dealer/retailer with any questions. 8-23 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. (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. Parking Over Things That Burn { CAUTION Things that can burn could touch hot exhaust parts under the vehicle and ignite. Do not park over papers, leaves, dry grass, or other things that can burn. 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.
