Your vehicle’s exhaust contains
carbon monoxide gas. You should
have no problem with carbon
monoxide entering the vehicle in
normal driving if you maintain your
vehicle properly.High levels of carbon monoxide can
collect rapidly in enclosed areas,
such as a garage. Do not run the
engine with the garage door closed.
Even with the door open, run the
engine only long enough to move the
vehicle out of the garage.If you must sit in your parked vehicle
with the engine running, even in an
unconf ined area, adjust the heating
and cooling system as f ollows:
Have the exhaust system inspected
f or leaks whenever:
The vehicle is raised f or an oil
change.
You notice a change in the sound
of the exhaust.
The vehicle was in an accident
that may have damaged the
underside. With the trunk open, airf low can pull
exhaust gas into your vehicle’s
interior and create a hazardous
condition. If you must drive with the
trunk open, open all the windows,
and set the heating and cooling
system as shown below.
