FUEL REQUIREMENTS
Your vehicle is designed to meet all emis-
sion regulations and provide excellent fuel
economy when using high quality regular
unleaded gasoline with an octane rating of
87. The use of premium gasoline is not recommended. The use of premium gasoline will provide
no benefit over high quality regular gasolines, and in
some circumstances, may result in poorer performance.
Light spark knock at low engine speeds is not harmful to
your engine. However, continued heavy spark knock at
high speeds can cause damage and immediate service is
required.
Poor quality gasoline can cause problems such as hard
starting, stalling and hesitations. If you experience these
symptoms, try another brand of “ regular ” gasoline be-
fore considering service for the vehicle.
Over 40 automobile manufacturers around the world
have issued and endorsed consistent gasoline specifica-
tions (the World Wide Fuel Charter, WWFC) to define
fuel properties necessary to deliver enhanced emissions,
engine performance, and durability for your vehicle. The
manufacturer recommends the use of gasolines that meet
the WWFC specifications if they are available.330 STARTING AND OPERATING

Reformulated Gasoline
Many areas of the country require the use of cleaner
burning gasoline referred to as “ Reformulated Gasoline ” .
Reformulated gasolines contain oxygenates, and are spe-
cifically blended to reduce vehicle emissions and im-
prove air quality.
The manufacturer supports the use of reformulated gaso-
lines. Properly blended reformulated gasolines will pro-
vide excellent performance and durability of engine and
fuel system components.
Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with oxy-
genates such as 10% ethanol, MTBE, and ETBE. Oxygen-
ates are required in some areas of the country during the
winter months to reduce carbon monoxide emissions.
Fuels blended with these oxygenates may be used in
your vehicle. CAUTION!DO NOT use gasolines containing Methanol. Use of
these blends may result in starting and driveability
problems and may damage critical fuel system com-
ponents.
Problems that result from using methanol/gasoline
blends are not the responsibility of the manufacturer.
While MTBE is an oxygenate made from Methanol, it
does not have the negative effects of Methanol.
MMT In Gasoline
MMT is a manganese containing metallic additive that is
blended into some gasoline to increase the octane num-
ber. Gasolines blended with MMT offer no performance
advantage beyond gasolines of the same octane number
without MMT. Gasolines blended with MMT have shown
to reduce spark plug life and reduce emission system STARTING AND OPERATING 331

performance in some vehicles. The manufacturer recom-
mends using gasolines without MMT. Since the MMT
content of gasoline may not be indicated on the pump,
you should ask your gasoline retailer whether or not
his/her gasoline contains MMT.
It is even more important to look for gasolines without
MMT in Canada, because MMT can be used at levels
higher than those allowed in the United States.
MMT is prohibited in Federal and California reformu-
lated gasolines.
Materials Added to Fuel
All gasoline sold in the United States is required to
contain effective detergent additives. Use of additional
detergents or other additives are not needed under
normal conditions and would result in additional cost.
Therefore you should not have to add anything to the
fuel. 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.
• The use of fuel additives which are now being sold as
octane enhancers is not recommended. Most of these332 STARTING AND OPERATING

products contain 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.
Carbon Monoxide Warnings
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 mainte-
nance. 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.
• Keep the liftgate closed when driving your vehicle to
prevent carbon monoxide and other poisonous ex-
haust gases from entering the vehicle. STARTING AND OPERATING 333

NOTE:
• Tighten the gas cap until you hear a “ clicking ” sound.
This is an indication that the gas cap is properly
tightened. If the gas cap is not secured properly the
Malfunction Indicator Light will turn on. Make sure
that the gas cap is tightened each time the vehicle is
refueled.
• When the fuel nozzle “ clicks ” or shuts off, the fuel
tank is full. WARNING!• Never have any smoking materials lit in or near
the vehicle when the gas cap is removed or the
tank filled.
• Never add fuel to the vehicle when the engine is
running.
• A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle. You
could be burned. Always place gas containers on
the ground while filling. STARTING AND OPERATING 335

IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate ac-
tion.
• On the highways — Slow down.
• In city traffic — While stopped, put transaxle in
neutral, but do not increase engine idle speed.
NOTE: There are steps that you can take to slow down
an impending overheat condition. If your air conditioner
is on, turn it off. The air conditioning system adds heat to
the engine cooling system and turning off the A/C
removes this heat. You can also turn the Temperature
control to maximum heat, the Mode control to floor, and
the fan control to High. This allows the heater core to act
as a supplement to the radiator and aids in removing heat
from the engine cooling system. CAUTION!Driving with a hot cooling system could damage
your vehicle. If temperature gauge reads “ H ” , pull
over and stop the vehicle. Idle the vehicle with the
air conditioner turned off until the pointer drops
back into the normal range. If the pointer remains on
the “ H ” , turn the engine off immediately, and call for
service. WHAT TO DO IN EMERGENCIES 345
