Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s performance:
•
The use of leaded gas is prohibited by Federal law. Using
leaded gasoline can impair engine performance, damage the
emission control system.
•
An out-of-tune engine, or certain fuel or ignition malfunctions,
can cause the catalytic converter to overheat. If you notice a
pungent burning odor or some light smoke, your engine may
be out of tune or malfunctioning and may require immediate
service. Contact your dealer for service assistance.
•
When pulling a heavy load or driving a fully loaded vehicle
when the humidity is low and the temperature is high, use a
premium unleaded fuel to help prevent spark knock. If spark
knock persists, lighten the load, or engine piston damage may
result.
•
The use of fuel additives which are now being sold as octane
enhancers is not recommended. Many of these products con-
tain high concentrations of methanol. Fuel system damage or
vehicle performance problems resulting from the use of such
fuels or additives is not the responsibility of the manufacturer.
NOTE: Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
