HONDA 2004 Civic Sedan - Owner's Manual - Manual (Page 49)

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.
With the trunk lid open, air flow can
pull exhaust gas into your vehicle’s
interior and create a hazardous
condition. If you must drive with the
trunk lid open, open all the windows
and set the heating and cooling
system as shown below.
If you must sit in your parked vehicle,
even in an unconfined area, with the
engine running, adjust the heating
and cooling system as follows:
Select the Fresh Air mode.
Select the
mode.
Turn the fan on high speed.
Set the temperature control to a
comfortable setting.
Have the exhaust system inspected
for leaks whenever:
The vehicle is raised for an oil
change.
You notice a change in the sound
of the exhaust.
The vehicle was in an accident
that may have damaged the under-
side.
