1. Catalytic converters routinely reach operating temperatures of 650 °C (1200 °F). Do not park the vehicle over any object or material that could ignite (dry leaves and grass, cardboard, puddles of oil, etc.). Catalytic converters will stay hot for some time after the engine has been shut off.
2. Some exhaust gas components (carbon monoxide) are toxic. Do not run the engine in confined areas or breathe concentrated exhaust gases. Prolonged breathing of exhaust gases can cause loss of consciousness and death.
3. Repair any leaks in the exhaust system as soon as possible. Hot gases escaping from a leak can ignite flammable materials and/or set the vehicle on fire. Exhaust from a leak may also circulate through the passenger compartment, causing symptoms such as throat, sinus, or eye irritation, light headedness, headaches and increased irritability. This hazard is particularly pronounced while driving with windows closed.
4. Be alert for fuel odors and excessive tailpipe emissions (black smoke etc.); these are problem indicators.
