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 (see the paragraph on tread
wear indicators). Refer to the Tire and Loading Informa-
tion 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, han-
dling, and ride of your vehicle. We recommend that you
contact your original equipment or an authorized tire
dealer with any questions you may have on tire specifi-
cations or capability.WARNING!
²Do not use a tire, wheel size or rating other than
that specified for your vehicle. Some combina-
tions of unapproved tires and wheels may change
suspension dimensions and performance charac-
teristics, resulting in changes to steering, han-
dling, 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.
²Never use a tire with a smaller load index or
capacity, other than what was originally equipped
on your vehicle. Using a tire with a smaller load
index could result in tire overloading and failure.
You could lose control and have an accident.
²Failure to equip your vehicle with tires having
adequate speed capability can result in sudden
tire failure and loss of vehicle control.
138 STARTING AND OPERATING

2.0L High Output Engine
Your engine is designed to meet all emis-
sion regulations and provide excellent fuel
economy and performance when using
high quality unleaded gasoline having an
octane rating of 91. The purchase of higher
octane is not recommended.
High quality unleaded gasoline having a minumum
octane rating of 87 may safely be used for your vehicle.
Use of these lower octane gasolines, however, may result
in reduced acceleration performance.
Spark Knock
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. Engine damage resulting from operation with a
heavy spark knock may not be covered by the new
vehicle warranty.
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 fuel referred to as Reformulated Gasoline. Re-
formulated gasolines contain oxygenates, and are specifi-
cally blended to reduce vehicle emissions and improve
air quality.
The manufacturer supports the use of reformulated gaso-
lines. Properly blended reformulated gasolines will pro-
vide excellent performance and durability for the engine
and fuel system components.
Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with mate-
rials called oxygenates such as 10% ethanol, MTBE and
ETBE. Oxygenates are required in some areas of the
142 STARTING AND OPERATING

Malfunction Indicator light to illuminate. The manufac-
turer recommends that you try a different brand of
unleaded gasoline having lower sulfur to determine if the
problem is fuel related prior to returning your vehicle to
an authorized dealer for service.
CAUTION!
If the Check Engine or Service Engine Soon light is
flashing, immediate service is required. See the On
Board Diagnostics paragraph in the Maintenance
section of this manual.
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 would result in unnecessary cost. There-
fore 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, and could result
in loss of warranty coverage.
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.

TRAILER TOWING
In this section you will find safety tips and information
on limits to the type of towing you can reasonably do
with your vehicle. Before towing a trailer carefully re-
view this information to tow your load as efficiently and
safely as possible.
To maintain warranty coverage, follow the requirements
and recommendations in this manual concerning ve-
hicles used for trailer towing.
Perform maintenance services as prescribed in the main-
tenance schedules manual. When your vehicle is used for
trailer towing, never exceed the gross axle weight rating
(GAWR) by the addition of:
²The tongue weight of the trailer.
²The weight of any other type of cargo or equipment
put in or on your vehicle.
²Remember that everything put in or on the trailer adds
to the load on your vehicle.
Warranty Requirements
The Manufacturer's Passenger Vehicle Warranty will
apply to vehicles used to tow trailers for non-commercial
use. However the following conditions must be met:
²The maximum trailer load for vehicles with the Stan-
dard 2.0L Engine and manual tranaxles is 1,500 lbs
(680 kg).
²The maximum trailer load for vehicles with the Stan-
dard 2.0L Engine and automatic transaxles is 1,000 lbs
(454 kg).
²Trailer towing is not recommended for vehicles with
the optional 2.0L Magnum Engine (R/T) and manual
transaxle.
²If using a manual transaxle vehicle for trailer towing,
all starts must be in FIRST gear to avoid excessive
clutch slippage.
²The maximum frontal area of the trailer cannot exceed
20 square feet (1.86 square meters).
²The trailer tongue load must be considered as part of
the combined weight of occupants and cargo, and
should never exceed the weight referenced on the Tire
148 STARTING AND OPERATING

HAZARD WARNING FLASHER
The flasher switch is on top of the steering column,
just behind the steering wheel. Depress the switch
and both cluster indicators and all front and rear direc-
tional signals will flash. Depress the switch again to turn
Hazard Warning Flashers off.
Do not use this emergency warning system when the
vehicle is in motion. Use it when your vehicle is disabled
and is creating a safety hazard for other motorists.If it is necessary to leave the vehicle to go for service, the
flasher system will continue to operate with the ignition
key removed and the vehicle locked.
NOTE:With extended use, the flasher 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 action.
²On the highways Ð Slow down.
²In city traffic Ð 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.
152 WHAT TO DO IN EMERGENCIES

CAUTION!
Driving with a hot cooling system could damage
your vehicle. If temperature gauge reads ªHº, 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 ªHº, 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, see Section 7, Maintenance, of this
manual. Follow the warnings under the Cooling
System Pressure Cap paragraph.
JACKING AND TIRE CHANGING
WARNING!
²Getting under a jacked-up vehicle is dangerous.
The vehicle could slip off the jack and fall on you.
You could be crushed. Never get any part of your
body under a vehicle that is on a jack. Never start
or run the engine while the vehicle is on a jack. If
you need to get under a raised vehicle, take it to a
service center where it can be raised on a lift.
²Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off
the road to avoid the danger of being hit when
operating the jack or changing the wheel.

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.
5. Remove the wheel nuts and pull the wheel and wheel
covers where applicable off the hub. Install the spare
wheel and wheel nuts with the cone shaped end of the
nuts toward the wheel. Lightly tighten the nuts. To avoid
the risk of forcing the vehicle off the jack, do not tighten
the nuts fully until the vehicle has been lowered.
WARNING!
To avoid possible personal injury, handle the wheel
covers with care to avoid contact with any sharp
edges.
NOTE:The wheel cover is held on the wheel by the
wheel nuts. When reinstalling original wheel, properlyalign the wheel cover to the valve stem, place the wheel
cover onto the wheel, then install the wheel nuts.
6. Lower the vehicle by turning the jack screw to the left.
7. Finish tightening the nuts. Push down on the wrench
while tightening the wheel nuts. Alternate nuts until each
nut has been tightened twice. Correct wheel nut torque is
100 ft. lbs. (135 N´m). If you are not sure about the
tightness, have them checked with a torque wrench by
your dealer or at a service station.
8. Remove the wheel blocks and lower the jack until it is
free. Stow the lug wrench, replaced tire, and jack. Secure
all parts using the means provided.
WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could endanger the occupants of the ve-
hicle. Always stow the jack parts and the spare tire in
the places provided.
9. Adjust the tire pressure as soon as possible.
