FUEL REQUIREMENTS
6.1L Engine
The 6.1L Engine is designed to meet all
emissions regulations and provide excel-
lent fuel economy and performance when
using high-quality premium unleaded
gasoline with an octane rating of 91 or
higher.
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 suchas hard starting, stalling, and hesitations. If you experi-
ence these symptoms, try another brand of gasoline
before considering service for the vehicle.
Over 40 auto manufacturers worldwide have issued and
endorsed consistent gasoline specifications (the World-
wide Fuel Charter, WWFC) which define fuel properties
necessary to deliver enhanced emissions, performance,
and durability for your vehicle. The manufacturer recom-
mends the use of gasolines that meet the WWFC speci-
fications, if they are available.
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.
STARTING AND OPERATING 321
5

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 or E85
Ethanol. Use of these blends may result in starting
and driveability problems and may damage critical
fuel system components.Problems that result from using methanol/gasoline or
E85 ethanol blends are not the responsibility of the
manufacturer. While MTBE is an oxygenate made from
methanol, it does not have the negative effects of metha-
nol.
MMT In Gasoline
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. It is even more important to
look for gasoline without MMT in Canada, because MMT
322 STARTING AND OPERATING

can be used at levels higher than those allowed in the
United States. MMT is prohibited in Federal and Califor-
nia reformulated gasoline.
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 is not needed under normal
conditions and they 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
and damage the emissions control system.
•An out-of-tune engine or certain fuel or ignition mal-
functions 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
your 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 performance problems
resulting from the use of such fuels or additives is not
the responsibility of the manufacturer.
NOTE:Intentional tampering with the emissions con-
trol system 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 trunk/liftgate closed when driving your
vehicle to prevent carbon monoxide and other poison-
ous exhaust gases from entering the vehicle.
ADDING FUEL
Fuel Filler Cap (Gas Cap)
The gas cap is located behind the fuel filler door on the
left side of the vehicle. Push in on the left side (near the
edge) of the fuel filler door to access the fuel filler cap. If
the gas cap is lost or damaged, be sure the replacement
cap is for use with this vehicle.
324 STARTING AND OPERATING

CAUTION!
•Damage to the fuel system or emissions control
system could result from using an improper fuel
tank filler tube cap (gas cap).
•A poorly fitting gas cap could let impurities into
the fuel system.
•A poorly fitting gas cap may cause the Malfunc-
tion Indicator Light (MIL) to turn on.
•To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling. 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.
NOTE:
•Tighten the gas cap until you hear a “clicking” sound.
This is an indication that the gas cap is tightened
properly. The MIL in the instrument cluster may turn

HAZARD WARNING FLASHER
The HAZARD switch is located in the switch bank
near the top center of the instrument panel. De-
press the switch to activate the flashers. When
activated, all directional turn signals will flash on and off
to warn oncoming traffic of an emergency. Push the
switch a second time to turn off the flashers.
This is an emergency warning system and it should not
be used when the vehicle is in motion. Use it when your
vehicle is disabled and it is creating a safety hazard for
other motorists.
When you must leave the vehicle to seek assistance, the
hazard warning flashers will continue to operate even
though the ignition switch is in the LOCK position.
NOTE:With extended use, the hazard earning flashers
may wear down your battery.
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 transmission 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 HI. This allows the heater core to act as
a supplement to the radiator and aids in removing heat
from the engine cooling system.
332 WHAT TO DO IN EMERGENCIES

CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the temperature gauge reads 240°F
(116°C) or greater pull over and stop the vehicle. Idle
the vehicle with the air conditioner turned off until
the pointer drops back into the normal range 200–
230°F (93–110°C). If the pointer remains at 240°F
(116°C) or greater and you hear a chime, turn the
engine off immediately and call for service.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call a service center if your
vehicle overheats. If you decide to look under the
hood yourself, refer to Section 7 and follow the
warnings under the Cooling System Pressure Cap
paragraph.
TIREFIT TIRE REPAIR
Small punctures, particularly those in the tread, can be
sealed with TIREFIT. Foreign objects (e.g., screws or
nails) should not be removed from the tire. TIREFIT can
be used in outside temperatures down to approximately
-4°F (-20°C).

6. TIREFIT sealant hose
WARNING!
•Do not attempt to repair a tire on the side of the vehicle close to
traffic. Pull far enough off the road to avoid the danger of being
hit when operating the jack or repairing a tire.
•Cuts or punctures larger than approximately 0.16 in. (4 mm), tire
damage caused by driving with extremely low tire pressure or on
a flat tire, or a damaged wheel can pose a hazard while driving.
TIREFIT should not be used in such circumstances. Do not drive
the vehicle under such circumstances. Contact your nearest
authorized dealer for assistance.
•Take care not to allow the contents of TIREFIT to come in contact
with hair, eyes or clothing. TIREFIT is harmful if inhaled,
swallowed, or absorbed through the skin: It causes skin, eye, and
respiratory irritation. Any contact with eyes or skin should be
flushed immediately with plenty of water. If clothing comes in
contact with TIREFIT, change clothing as soon as possible.
•In case of allergic reaction or rash, consult a physician immedi-
ately. Keep TIREFIT out of reach of children. If swallowed, rinse
mouth immediately with plenty of water and drink plenty of
water. Do not induce vomiting! Consult a physician immediately.
•Keep away from open flame or heat source.

8. Press the switch (3) on the air pump to I (ON). The air
pump should start to inflate the tire and the tire sealant
(white fluid) will flow from the sealant bottle (5) through
the TIREFIT sealant hose (6) and into the tire.
9. Allow the air pump to run for five minutes and then
read the pressure gauge (4). If the tire inflates to 26 psi
(1.8 bar) or greater, proceed to Step 19 of this procedure.
If not, proceed to the following step.
10. Press the AIR PUMP switch (3) to 0 (OFF). Then,
disconnect the TIREFIT system from the tire and place it
back in the vehicle.
11. Release the parking brake and drive the vehicle back
and forth approximately 30 ft (9.1 m) to distribute the
sealant more evenly within the tire.
12. Turn on the hazard warning flashers.
13. Move the shift lever to the PARK position, turn off
the engine, and set the parking brake.14. Disconnect the air pump hose (1) from the underside
of the sealant bottle (5) by flipping the hose valve open.
15. Connect the air pump hose valve to the tire valve and
flip the hose valve closed.
16. Leave the parking brake set and the shift lever in
PARK and start the engine.
17. Press the switch (3) on the air pump to I (ON). The air
pump should inflate the tire to at least 26 psi (1.8 bar)
within five minutes. If the tire inflates to this level,
proceed to the following step.NOTE:If a tire pressure of
26 psi (1.8 bar) is not obtained within five minutes, the
tire is too badly damaged. Do not attempt to drive the
vehicle further. Call for assistance.
18. With a tire pressure of no less than 26 psi (1.8 bar)
press the AIR PUMP switch (3) to 0 (OFF) and turn off the
engine. Then, disconnect the TIREFIT system from the
