 Avoid inhaling the engine exhaust. It contains

 Do not run the engine in a garage or enclosed area
except for the time needed to drive the vehicle in or

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