Materials Added To Fuel
Besides using unleaded gasoline with the
proper octane rating, gasolines that contain
detergents, corrosion and stability additives
are recommended. Using gasolines that have
these additives will help improve fuel
economy, reduce emissions, and maintain
vehicle performance.
Designated TOP TIER Detergent
Gasoline contains a higher level of
detergents to further aide in mini-
mizing engine and fuel system
deposits. When available, the usage of TOP
TIER Detergent Gasoline is recommended.

Indiscriminate use of fuel system cleaning
agents should be avoided. Many of these
materials intended for gum and varnish
removal may contain active solvents or similar
ingredients. These can harm fuel system
gasket and diaphragm materials.

Fuel System Cautions
Follow these guidelines to maintain your
vehicle'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
for a list of TOP TIER
malfunctioning and may require imme-
diate service. Contact an authorized
dealer for service assistance.
CAUTION!

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.
