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.
