Avoid inhaling the engine exhaust.

It contains carbon monoxide, which is a colorless and odorless gas. It can cause unconsciousness or even death.

Make sure the exhaust system has no holes or loose connections. The system should be checked from time to time. If you hit something, or notice a change in the sound of the exhaust, have the system checked immediately.

Do not run the engine in a garage or enclosed area except for the time needed to drive the vehicle in or out. The exhaust gases cannot escape, making this a particularly dangerous situation.

Do not remain for a long time in a parked vehicle with the engine running.

If it is unavoidable, however, do so only in an unconfined area and adjust the heating or cooling system to force outside air into the vehicle.

Keep the back door closed while driving. An open or unsealed back door may cause exhaust gases to be drawn into the vehicle.

To allow proper operation of your vehicle’s ventilation system, keep the inlet grilles in front of the windshield clear of snow, leaves, or other obstructions.

If you smell exhaust fumes in the vehicle, open the windows and close the back door to ensure plenty of fresh air enters the vehicle.
