8-18 Driving and Operating
ENGINE EXHAUST
Warning
Engine exhaust contains carbon
monoxide (CO) which cannot be
seen or smelled. Exposure to CO can
cause unconsciousness and even
death.
Exhaust may enter the vehicle if:
 The vehicle idles in areas with
poor ventilation (parking garages,
tunnels, deep snow that may block
underbody airflow or tail pipes).
 The exhaust smells or sounds
strange or different.
 The exhaust system leaks due to
corrosion or damage.
 The vehicle exhaust system has been
modified, damaged or improperly
repaired.

ENGINE EXHAUST
Caution
Use of fuel with low quality or too
low cetane number may damage the
engine, the catalytic converter or
electronic components.
Unburnt fuel will overheat and
damage the catalytic converter.
Therefore avoid excessive use of
starter, running the fuel tank dry and
starting the engine by pushing or
towing.
In the event of misfiring, uneven engine
running, a reduction in engine perfor-
mance or other unusual problems, have
the cause of the fault rectified by a
CHEVROLET retailer as soon as
possible. In an emergency, driving can
be continued for a short period, keeping
vehicle speed and engine speed low.
The catalytic converter reduces the
amount of harmful substances in the
exhaust gas.
Catalytic Converter
 There are holes or openings in the
vehicle body from damage or
aftermarket modifications that are
not completely sealed.
If unusual fumes are detected or if it
is suspected that exhaust is coming
into the vehicle:
 Drive it only with the windows
completely down.
 Have the vehicle repaired imme-
diately.
Never park the vehicle with the
engine running in an enclosed area
such as a garage or a building that has
no fresh air ventilation.
