Engine Exhaust Gas Warning
A properly maintained car is your best protection against ex-
haust gas entering the passenger compartment.
The exhaust system should be thoroughly inspected by a com-
petent 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.
Avoid breathing exhaust gases. They contain carbon
monoxide, which is a colorless, odorless gas that can cause
loss of consciousness and eventual death. If you suspect
that exhaust gas is entering the passenger compartment,
have the cause determined and corrected as soon as possi-
ble. If you must drive 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.
If you must sit in a parked car with the engine running for
more than a short time, adjust the heating/ventilation
system as follows:
1. [DX]
Slide the function lever to and push the but-
ton off.
[LX, EX]
Select the and positions.
2. Set the temperature lever/control dial for best comfort.
3. Turn the fan to the highest speed.
NOTE: To insure proper operation of the car's ventilation
system, keep the front air inlet clear of snow, mud, leaves or
other obstructions.
