Limited Warranty.
Poor quality gasoline can cause problems such
as hard starting, stalling, and hesitations. If you
experience these symptoms, try another brand
of gasoline before considering service for the
vehicle.
REFORMULATED GASOLINE
Many areas of the country require the use of
cleaner burning gasoline referred to as
“Reformulated Gasoline”. Reformulated
gasoline contains oxygenates and are
specifically blended to reduce vehicle
emissions and improve air quality.
The use of reformulated gasoline is
recommended. Properly blended reformulated
gasoline will provide improved performance
and durability of engine and fuel system
components.
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
minimizing engine and fuel system
deposits.

20_WD_OM_EN_USC_t.book Page 352

TECHNICAL SPECIFICATIONS353
When available, the usage of TOP TIER
Detergent Gasoline is recommended. Visit
www.toptiergas.com for a list of TOP TIER
Detergent Gasoline Retailers.
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.
GASOLINE/OXYGENATE BLENDS
Some fuel suppliers blend unleaded gasoline
with oxygenates such as ethanol. Problems that result from using gasoline
containing more than 15% ethanol (E-15) or
gasoline containing methanol are not the
responsibility of the manufacturer and may void
or not be covered under New Vehicle Limited
Warranty.
DO NOT USE E-85 IN NON-FLEX FUEL
V
EHICLES
Non-Flex Fuel Vehicles (FFV) are compatible
with gasoline containing up to 15% ethanol
(E-15). Use of gasoline with higher ethanol
content may void the New Vehicle Limited
Warranty.
If a Non-FFV vehicle is inadvertently fueled with
E-85 fuel, the engine will have some or all of
these symptoms:
Operate in a lean mode.
OBD II Malfunction Indicator Light on.
Poor engine performance.
Poor cold start and cold drivability.
Increased risk for fuel system component
corrosion.
CNG AND LP FUEL SYSTEM
M
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 the
manufacturer and may void or not be covered
under the New Vehicle Limited Warranty.
MMT IN GASOLINE
Methylcyclopentadienyl Manganese Tricarbonyl
(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.
CAUTION!
DO NOT use E-85, gasoline containing
methanol, or gasoline containing more than
15% ethanol (E-15). Use of these blends may
result in starting and drivability problems,
damage critical fuel system components,
cause emissions to exceed the applicable
standard, and/or cause the Malfunction
Indicator Light to illuminate. Please observe
pump labels as they should clearly
communicate if a fuel contains greater than
15% ethanol (E-15).

354TECHNICAL SPECIFICATIONS
(Continued)
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.
CARBON MONOXIDE WARNINGS
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 the manufacturer and may void or
not be covered under the New Vehicle
Limited Warranty.
CAUTION! (Continued)
WARNING!
Carbon monoxide (CO) in exhaust gases is
deadly. Follow the precautions below to
prevent carbon monoxide poisoning:
Do not inhale exhaust gases. They contain
carbon monoxide, a colorless and odorless
gas, which can kill. Never run the engine in
a closed area, such as a garage, and never
sit in a parked vehicle with the engine
running for an extended period. If the
vehicle is stopped in an open area with the
engine running for more than a short
period, adjust the ventilation system to
force fresh, outside air into the vehicle.
Guard against carbon monoxide with
proper maintenance. Have the exhaust
system inspected every time the vehicle is
raised. Have any abnormal conditions
repaired promptly. Until repaired, drive with
all side windows fully open.
