gasolines, and in some circumstances may result in
poorer performance.
4.0L Gasoline Engine
The 4.0L 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 premium gasoline
is not recommended. Under normal conditions, the use of
premium gasoline will not provide a benefit over high-
quality regular and mid-grade 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 ªregularº 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.
Reformulated Gasoline
Many areas of the country require the use of cleaner
burning gasoline referred to as ªReformulated Gasolineº.
Reformulated gasolines contain oxygenates, and are spe-
cifically blended to reduce vehicle emissions and im-
prove air quality.
378 STARTING AND OPERATING

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:
²The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine performance
and damage the emission control system.
²An 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.
380 STARTING AND OPERATING

CAUTION!
Damage to the fuel system or emission control sys-
tem could result from using an improper fuel tank
filler tube cap (gas cap). A poorly fitting cap could let
impurities into the fuel system and may cause the
Malfunction Indicator Light (MIL) to turn on due to
fuel vapors escaping from the system.
CAUTION!
To avoid fuel spillage and overfilling, do not ªtop
offº the fuel tank after filling.
NOTE:When the fuel nozzle ªclicksº or shuts off, the
fuel tank is full.
WARNING!
²Never have any smoking materials lit in or near
the vehicle when the gas cap is removed or the
tank filled.
²Never add fuel when the engine is running. This is
in violation of most state and federal fire regula-
tions and will cause the malfunction indicator
light to turn on.
NOTE:
²Tighten the fuel filler cap until you hear a ªclickingº
sound. This is an indication that the fuel filler cap is
properly tightened.
²If the gas cap is not tightened properly, the Malfunc-
tion Indicator Light may come on. Be sure the gas cap
is tightened every time the vehicle is refueled.

Trailer Hitch Classifications
Your vehicle may be factory-equipped for safe towing of
trailers weighing over 2,000 lbs (907 kg) with the optional
Trailer Tow Prep Package. See an authorized dealer for
package content.
The following chart provides the industry standard for
the maximum trailer weight a given trailer hitch class can
tow and should be used to assist you in selecting the
correct trailer hitch for your intended towing condition.Trailer Hitch Classification Definitions

Towing Requirements Ð Trailer Lights and Wiring
Whenever you pull a trailer, regardless of the trailer size,
stop lights and turn signals on the trailer are required for
motoring safety.
The Trailer Tow Package may include a four-pin or a
seven-pin wiring harness. Use a factory approved trailer
harness and connector.
NOTE:Do not cut or splice wiring into the vehicles
wiring harness.
The electrical connections are all complete to the vehicle
but you must mate the harness to a trailer connector.
Refer to the following four-pin connector and seven-pin
connector illustrations.
Four-Pin Connector
404 STARTING AND OPERATING

NOTE:
²Check the automatic transmission fluid level before
towing.
²The six-speed automatic transmission is sealed and
requires an authorized dealer service center to check
the transmission fluid.
Towing Tips Ð Electronic Speed Control (If
Equipped)
²
Don't use in hilly terrain or with heavy loads.
²When 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.
²Use speed control in flat terrain and with light loads to
maximize fuel efficiency.
Towing Tips Ð Cooling System
To reduce potential for engine and transmission over-
heating, take the following actions:
²City Driving
When stopped for short periods of time, put transmission
gear selector lever in NEUTRAL but do not increase
engine idle speed.
²Highway Driving
Reduce speed.
²Air Conditioning
Turn off temporarily.
²Refer to Cooling System Operating information in the
Maintenance section of this manual for more informa-
tion.

CAUTION!
Do not attempt to raise the vehicle by jacking on
locations other than those indicated in Step 5.
6. Place the wrench on the jack screw and turn to the
right until the jack head is properly engaged in the
described location.Do not raise the vehicle until you are
sure the jack is securely engaged.
7. Raise the vehicle by turning the jack screw to the right,
using the swivel wrench. Raise the vehicle only until the
tire just clears the surface and enough clearance is
obtained to install the spare tire. Minimum tire lift
provides maximum stability.
WARNING!
Raising the vehicle higher than necessary can make
the vehicle less stable. It could slip off the jack and
hurt someone near it. Raise the vehicle only enough
to remove the tire.
8. Remove the wheel lug nuts, for vehicles with wheel
covers, remove the cover from the wheel by hand. Do not
pry the wheel cover off. Then pull the wheel off the hub.
9. Install the compact spare tire. Lightly tighten the lug
nuts. To avoid the risk of forcing the vehicle off the jack,
do not tighten the lug nuts fully until the vehicle has been
lowered.
NOTE:Do not install the wheel cover on the compact
spare.
Do not use a hammer or force to install the wheel covers.
