METHYLCYCLOPENTADIENYL
M
ANGANESE TRICARBONYL (MMT) IN
G
ASOLINE
MMT is a manganese-containing metallic additive
that is blended into some gasoline to increase
octane. Gasoline blended with MMT provides no
performance advantage beyond gasoline of the
same octane number without MMT. Gasoline
blended with MMT reduces spark plug life and
reduces emissions system performance in some
vehicles. The manufacturer recommends that
gasoline without MMT be used in your vehicle. The
MMT content of gasoline may not be indicated on
the gasoline pump; therefore, you should ask your
gasoline retailer whether the gasoline contains
MMT. MMT is prohibited in Federal and California
reformulated gasoline.
FUEL SYSTEM CAUTIONS
NOTE:Intentional tampering with the emissions control
system can result in civil penalties being assessed
against you.
CAUTION!
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 emis -
sions 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 an autho -
rized dealer for service assistance.
The use of fuel additives, which are now being
sold as octane enhancers, is not recom -
mended. Most of these products contain high
concentrations of methanol. Fuel system
damage or vehicle performance problems
resulting from the use of such fuels or addi -
tives is not the responsibility of the manufac-
turer and may void or not be covered under
the New Vehicle Limited Warranty.
CAUTION!

SUGGESTIONS FOR OBTAINING SERVICE
FOR YOUR VEHICLE
PREPARE FOR THE APPOINTMENT
All work to be performed may not be covered by the
warranty. Discuss additional charges with the
service manager. Keep a maintenance log of your
vehicle's service history. This can often provide a
clue to the current problem.
PREPARE A LIST
Make a written list of your vehicle's problems or the
specific work you want done. If you've had an
accident or work done that is not on your
maintenance log, let the service advisor know.
BE REASONABLE WITH REQUESTS
If you list a number of items and you must have
your vehicle by the end of the day, discuss the
situation with the service advisor and list the items
in order of priority. At many authorized dealers, you
may obtain a rental vehicle (additional charges
may apply). If you need a rental, it is advisable to
make these arrangements when you call for an
appointment.
