CNG AND LP FUEL SYSTEM

ODIFICATIONS
Modifications that allow the engine to run on
Compressed Natural Gas (CNG) or Liquid Propane
(LP) may result in damage to the engine, emissions,
and fuel system components. Problems that result
from running CNG or LP are not the responsibility
of FCA and may void the New Vehicle Limited
Warranty.
METHYLCYCLOPENTADIENYL

ANGANESE TRICARBONYL (MMT) I N
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. FCA 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 emissions control system.
An out-of-tune engine or certain fuel or igni-
tion 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 malfunc-
tioning and may require immediate service.
Contact an authorized dealer for service
assistance.
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 FCA and may void or not be covered
under the New Vehicle Limited Warranty.
