Indiscriminate use of fuel system cleaning
agents should be avoided. Many of these mate-
rials intended for gum and varnish removal may
contain active solvents or similar ingredients.
These can harm fuel system gasket and dia-
phragm materials.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your ve-
hicle’s performance:
•
The use of leaded gasoline is prohibited by
Federal law. Using leaded gasoline can
impair engine performance and damage
the emissions control system.
•
An out-of-tune engine or certain fuel or
ignition malfunctions can cause the cata-
lytic converter to overheat. If you notice a
pungent burning odor or some light smoke,
your engine may be out of tune or malfunc-
tioning and may require immediate service.
Contact your authorized dealer for service
assistance.

CAUTION! (Continued)
•
The use of fuel additives, which are now
being sold as octane enhancers, is not
recommended. Most of these products
contain high concentrations of methanol.
Fuel system damage or vehicle perfor-
mance problems resulting from the use of
such fuels or additives is not the responsi-
bility of the manufacturer and may void or
not be covered under the New Vehicle
Limited Warranty.
NOTE:
Intentional tampering with the emissions
control system can result in civil penalties
being assessed against you.

WARNING! (Continued)
•
Do not inhale exhaust gases. They contain
carbon monoxide, a colorless and odorless
gas, which can kill. Never run the engine in
a closed area, such as a garage, and never
sit in a parked vehicle with the engine
running for an extended period. If the ve-
hicle is stopped in an open area with the
engine running for more than a short pe-
riod, adjust the ventilation system to force
fresh, outside air into the vehicle.
•
Guard against carbon monoxide with
proper maintenance. Have the exhaust
system inspected every time the vehicle is
raised. Have any abnormal conditions re-
paired promptly. Until repaired, drive with
all side windows fully open.
