Exhaust gas contains colorless and odorless carbon monoxide (CO), which is toxic even in low concentrations. Carbon monoxide can cause unconsciousness and even death if inhaled.
Never start or let the engine running in an enclosed, unventilated area. It is not recommended to sit in your car for prolonged periods with the engine on and the car not moving.
Exhaust System Fire Hazard
Exhaust fumes and the exhaust system are very hot when the engine is running. The exhaust system remains hot for some time after the engine is turned off.
Do not park or drive your vehicle where combustible materials, such as dry grass or leaves, can come into contact with the hot exhaust system.
If your car catches on fire for any reason, call the fire department. Do not endanger your life by attempting to put out the fire.
An unattended vehicle with a running engine is potentialy hazardous. If warning lights come on to indicate improper operation, no one would be present to observe the light and turn off the engine.
Never leave the engine idling unattended.
