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 emission 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
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:
²The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine performance,
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 dealer for service assistance.
²The 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:
²Do 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.
328 STARTING AND OPERATING
Page 329 of 457

²Guard 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.
²Keep the liftgate closed when driving your vehicle to
prevent carbon monoxide and other poisonous ex-
haust gases from entering the vehicle.
ADDING FUEL
Fuel Filler Cap (Gas Cap)
As a reminder, a fuel icon with an arrow
indicating which side of the vehicle the fuel
filler door is located on, is located in the
instrument cluster, just below the Fuel Gage.
The gas cap is located behind the fuel filler door on the
left side of the vehicle. If the gas cap is lost or damaged,
be sure the replacement cap is for use with this vehicle.
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.
STARTING AND OPERATING 329

Page 330 of 457

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 may cause the malfunction indicator
light to turn on.
²Failure to follow the above may result in serious
injury or even death.
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 tighten properly, the Malfunction
Indicator Light may come on. Be sure the gas cap is
tightened every time the vehicle is refueled.
WARNING!
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.
Loose Fuel Filler Cap Message
²
If thegASCAPmessage is displayed in the instrument
cluster, this signifies a leak or change in the evapora-
tive system is detected. Sometimes this is the result of
a loosely fitting (or possibly damaged) filler cap.
330 STARTING AND OPERATING
Page 331 of 457

Tighten the fuel filler cap properly and press the
odometer reset button to turn thegASCAPmessage
off.
²Make sure that the fuel filler cap is tightened each time
the vehicle is refueled.
²If the problem continues, the message will appear the
next time the vehicle is started. See your authorized
dealer service center as soon as possible. See Section 7
of this manual for more information.
VEHICLE LOADING
The load carrying capacity of your vehicle is shown in the
charts that follow. This information should be used for
passenger and luggage loading as indicated.
If the seatbacks are folded for carrying cargo, do not
exceed the specified GVWR and GAWR.
Vehicle Certification Label
Your vehicle has a certification label attached to the rear
of the driver's door.
The label contains the following information:
²Name of manufacturer
²Month and year of manufacture
²Gross Vehicle Weight Rating (GVWR)
²Gross Axle Weight Rating (GAWR) front
²Gross Axle Weight Rating (GAWR) rear
²Vehicle Identification Number (VIN)
²Type of Vehicle

Towing Tips Ð Electronic Speed Control (If
Equipped)
þ
Don't use in hilly terrain or with heavy loads.
þWhen 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.
þUse 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:
þCity Driving
When stopped for short periods of time, put transmission
in neutral but do not increase engine idle speed.
þHighway Driving
Reduce speed.
þAir Conditioning
Turn off temporarily.
þrefer to Cooling System Operating information in the
Maintenance section of this manual for more informa-
tion.
RECREATIONAL TOWING (BEHIND
MOTORHOME, ETC.)
TOWING THIS VEHICLE BEHIND ANOTHER
VEHICLE (Flat towing with all four wheels on the
ground)
Recreational towing for this vehicle is not recommended.
NOTE:If the vehicle requires towing make sure all four
wheels are off the ground.
348 STARTING AND OPERATING
Page 360 of 457

NOTE:When reinstalling the wheel center cap, insure
that the valve stem symbol on the back of the cap is
pointed toward the wheel valve stem. Install the center
cap using hand pressure only. Do not use a hammer.
Wheel Nuts
All wheel nuts should be tightened occasionally to elimi-
nate the possibility of wheel studs being sheared or the
bolt holes in the wheels becoming elongated. This is
especially important during the first few hundred miles
of operation, and after each time a tire is changed, to
allow the wheel nuts to become properly set. All nuts
should first be firmly seated against the wheel. The nuts
should then be tightened to recommended torque.
Tighten the nuts to final torque in increments. Progress
around the bolt circle, tightening the nut opposite to the
nut just previously tightened until final torque is
achieved. Recommended torque is 130 N´m (95 ft. lbs).
JUMP-STARTING PROCEDURE
WARNING!
²Do not attempt to push or tow your vehicle to get it started.
Vehicles equipped with an automatic transmission cannot
be started this way. Unburned fuel could enter the catalytic
converter and once the engine has started, ignite and
damage the converter and vehicle. If the vehicle has a
discharged battery, booster cables may be used to obtain a
start from another vehicle. This type of start can be danger-
ous if done improperly, so follow this procedure carefully.
²Battery fluid is a corrosive acid solution; do not allow
battery fluid to contact eyes, skin or clothing. Don't lean
over battery when attaching clamps or allow the clamps to
touch each other. If acid splashes in eyes or on skin, flush
contaminated area immediately with large quantities of
water.
²A battery generates hydrogen gas which is flammable and
explosive. Keep flame or spark away from the vent holes.
Do not use a booster battery or any other booster source
with an output that exceeds 12 volts.
²Take care to avoid the radiator cooling fan whenever the
hood is raised. It can start anytime the ignition switch is on.
You can be hurt by the fan.
