For 1990-2009 cars

It is better not to park with the engine running. But if you ever have to, here are some things to know.

Caution: Idling a vehicle in an enclosed area with poor ventilation is dangerous. Engine exhaust may enter the vehicle. Engine exhaust contains Carbon Monoxide (CO) which cannot be seen or smelled. It can cause unconsciousness and even death. Never run the engine in an enclosed area that has no fresh air ventilation. For more information, see Engine Exhaust.

Caution: It can be dangerous to get out of the vehicle if the shift lever is not fully in the appropriate position with the parking brake firmly set. The vehicle can roll. To determine the appropriate position see Parking the Vehicle . Do not leave the vehicle when the engine is running unless you have to. If you have left the engine running, the vehicle can move suddenly. You or others could be injured. To be sure the vehicle will not move, even when you are on fairly level ground, always set the parking brake and move the shift lever to the appropriate position as described under Parking the Vehicle .

Follow the proper steps to be sure the vehicle will not move. See Parking the Vehicle and Parking Brake.
