A properly maintained car is your best protection against exhaust
gas entering the passenger compartment.
The exhaust system should be thoroughly inspected by a compe-
tent mechanic whenever:
The car is raised for oil change.
You notice a change in the sound of the exhaust.
The exhaust system or the rear or underside of the car is
damaged.

which is a colorless, odorless gas that can cause loss of con-
sciousness and eventual death. If you suspect that exhaust gas
is entering the passenger compartment, have the cause deter-

under these conditions, drive only with all windows fully open.
Do not drive with the trunk lid open. An open trunk lid may draw
exhaust gases into the passenger compartment. If you must
drive with the trunk lid open, drive only with all the windows
wide open.
Do not run the engine in confined areas, such as garages, any
longer than necessary to move the car in or out.
