Tread Wear Indicators
Tread wear indicators are in the original equipment tires
to help you in determining when your tires should be
replaced.
These indicators are molded into the bottom of the tread
grooves. They will appear as bands when the tread depth becomes approximately 1/16 in (2 mm). When the tread
is worn to the tread wear indicators, the tire should be
replaced.
Life of Tire
The service life of a tire is dependent upon varying
factors including but not limited to:
² Driving style
² Tire pressure
² Distance driven
WARNING!Tires and spare tire should be replaced after six years,
regardless of the remaining tread. Failure to follow
this warning can result in sudden tire failure. You
could lose control and have an accident resulting in
serious injury or death.306 STARTING AND OPERATING

Keep dismounted tires in a cool, dry place with as little
exposure to light as possible. Protect tires from contact
with oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance of many
characteristics. They should be inspected regularly for
wear and correct cold tire inflation pressure. The manu-
facturer strongly recommends that you use tires equiva-
lent to the originals in size, quality and performance
when replacement is needed (refer to the paragraph on
ªTread Wear Indicatorsº). Refer to the ªTire and Loading
Informationº placard for the size designation of your tire.
The service description and load identification will be
found on the original equipment tire. Failure to use
equivalent replacement tires may adversely affect the
safety, handling, and ride of your vehicle. We recommend
that you contact your original equipment or an autho-
rized tire dealer with any questions you may have on tire
specifications or capability. WARNING!Do not use a tire, wheel size or rating other than that
specified for your vehicle. Some combinations of
unapproved tires and wheels may change suspension
dimensions and performance characteristics, result-
ing in changes to steering, handling, and braking of
your vehicle. This can cause unpredictable handling
and stress to steering and suspension components.
You could lose control and have an accident resulting
in serious injury or death. Use only the tire and
wheel sizes with load ratings approved for your
vehicle. STARTING AND OPERATING 307

3.5L ENGINE
The 3.5L engine is designed to meet all
emissions regulations and provide satisfac-
tory fuel economy and performance when
using high-quality unleaded gasoline hav-
ing an octane range of 87 to 89. The manu-
facturer recommends the use of 89 octane
for optimum performance. The use of pre-
mium gasoline is not recommended. Un-
der normal conditions, the use of premium
gasoline will not provide a benefit over
high quality unleaded ªregularº and ªmid-
gradeº 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 gasoline (with the ap-
propriate octane rating for your engine) before consider-
ing 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) which
define fuel properties necessary to deliver enhanced
emissions, engine performance, and durability for your
vehicle. The manufacturer recommends the use of gaso-
lines that meet the WWFC specifications if they are
available.
REFORMULATED GASOLINE
Many areas of the country require the use of cleaner
burning gasoline referred to as ªReformulated Gasoline.º320 STARTING AND OPERATING

² 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 authorized dealer for service assistance.
² 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 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:
² 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. STARTING AND OPERATING 323

STARTING
The characteristics of E-85 fuel make it unsuitable for use
when ambient temperatures fall below 0ÉF (-18ÉC). In the
range of 0ÉF (-18ÉC) to 32ÉF (0ÉC), you may experience an
increase in the time it takes for your engine to start, and
a deterioration in driveability (sags and/or hesitations)
until the engine is fully warmed up.
CRUISING RANGE
Because E-85 fuel contains less energy per gallon than
gasoline, you will experience an increase in fuel con-
sumption. You can expect your fuel economy and driving
range to decrease by about 30% compared to gasoline
operation.
REPLACEMENT PARTS
Many components in your Flexible Fuel Vehicle (FFV) are
designed to be compatible with ethanol. Always be sure
that your vehicle is serviced with correct ethanol com-
patible parts. CAUTION!Replacing fuel system components with non-ethanol
compatible components can damage your vehicle.
MAINTENANCE
CAUTION!Do not use ethanol mixture greater than 85% in your
vehicle. It will cause difficulty in cold starting and
may affect driveability. STARTING AND OPERATING 327

The bar code allows a computer scanner to read the
Vehicle Identification Number (VIN).
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, and cargo. The total
load must be limited so that you do not exceed the
GVWR.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front and rear
axles. Distribute the load over the front and rear axles
evenly. Make sure that you do not exceed either front or
rear GAWR. WARNING!Because the front wheels steer the vehicle, it is
important that you do not exceed the maximum front
or rear GAWR. A dangerous driving condition can
result if either rating is exceeded. You could lose
control of the vehicle and have an accident.
Overloading
The load carrying components (axle, springs, tires,
wheels, etc.) of your vehicle will provide satisfactory
service as long as you do not exceed the GVWR and front
and rear GAWR.
The best way to figure out the total weight of your
vehicle is to weigh it when it is fully loaded and ready for
operation. Weigh it on a commercial scale to insure that it
is not over the GVWR.332 STARTING AND OPERATING

Figure out the weight on the front and rear of the vehicle
separately. It is important that you distribute the load
evenly over the front and rear axles.
Overloading can cause potential safety hazards and
shorten useful service life. Heavier axles or suspension
components do not necessarily increase the vehicle's
GVWR.
Loading
To load your vehicle properly, first figure out its empty
weight, axle by axle and side by side. Store heavier items
down low and be sure you distribute their weight as
evenly as possible. Stow all loose items securely before
driving. If weighing the loaded vehicle shows that you
have exceeded either GAWR, but the total load is within
the specified GVWR, you must redistribute the weight.
Improper weight distribution can have an adverse effect
on the way your vehicle steers and handles and the way
the brakes operate. A loaded vehicle is shown in the illustration. Note that
neither the GVWR nor the GAWR capacities have been
exceeded.

Automatic Transaxle
The DRIVE range can be selected when towing. How-
ever, if frequent shifting occurs while in this range, third
gear for a four-speed automatic and the fifth gear for a
six-speed AutoStick t should be selected.
NOTE: Using third or fifth instead of DRIVE while
operating the vehicle under heavy operating conditions,
will improve performance and extend transaxle life by
reducing excessive shifting and heat build-up. This ac-
tion will also provide better engine braking.
If you REGULARLY TOW a trailer for more than 45
minutes of continuous operation, then change the auto-
matic transaxle fluid and filter according to the interval
specified for ªpolice, taxi, fleet, or frequent trailer tow-
ingº in the ªMaintenance Scheduleº in this manual.
NOTE: Check the four-speed automatic transaxle fluid
level before towing. AutoStick t sixÐspeed transmission is sealed and the fluid level cannot be checked. See your
authorized dealership service center for assistance.
Electronic Speed Control Ð (If Equipped)
² Don't use in hilly terrain or with heavy loads.
² When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
² Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Cooling System
To reduce potential for engine and transaxle overheating,
take the following actions:
² City Driving
When stopped for short periods of time, put transaxle in
neutral and increase engine idle speed.344 STARTING AND OPERATING
