WARNING!
•The ABS cannot prevent the natural laws of phys-
ics from acting on the vehicle, nor can it increase
braking or steering efficiency beyond that af-
forded by the condition of the vehicle brakes and
tires or the traction afforded.
•The ABS cannot prevent accidents, including
those resulting from excessive speed in turns,
following another vehicle too closely, or hydro-
planing. Only a safe, attentive, and skillful driver
can prevent accidents.
•The capabilities of an ABS-equipped vehicle must
never be exploited in a reckless or dangerous
manner which could jeopardize the user’s safety
or the safety of others.The ABS light monitors the ABS System. The
light will come on when the ignition switch is
turned to the ON position and may stay on for
as long as four seconds.
If the ABS light remains on or comes on while driving, it
indicates that the Anti-Lock portion of the brake system
is not functioning and that service is required. However,
the conventional brake system will continue to operate
normally if the BRAKE warning light is not on.
If the ABS light is on, the brake system should be serviced
as soon as possible to restore the benefits of Anti-Lock
brakes. If the ABS light does not come on when the
ignition switch is turned to the ON position, have the
bulb repaired as soon as possible.
If both the Brake Warning light and the ABS light remain
on, the ABS and Electronic Brake Force Distribution
(EBD) systems are not functioning. Immediate repair to
the ABS is required.
280 STARTING AND OPERATING

POWER STEERING
The standard power steering system will give you good
vehicle response and increased ease of maneuverability
in tight spaces. The system will provide mechanical
steering capability if power assist is lost.
If for some reason the power assist is interrupted, it will
still be possible to steer your vehicle. Under these condi-
tions, you will observe a substantial increase in steering
effort, especially at very low vehicle speeds and during
parking maneuvers.
NOTE:Increased noise levels at the end of the steering
wheel travel are considered normal and do not indicate
that there is a problem with the power steering system.
Upon initial start-up in cold weather, the power steering
pump may make noise for a short amount of time. This is
due to the cold, thick fluid in the steering system. This
noise should be considered normal, and it does not in any
way damage the steering system.WARNING!
Continued operation with reduced power steering
assist could pose a safety risk to yourself and others.
Service should be obtained as soon as possible.
CAUTION!
Prolonged operation of the steering system at the end
of the steering wheel travel will increase the steering
fluid temperature and it should be avoided when
possible. Damage to the power steering pump may
occur.

Many states have laws requiring tire replacement at this
point.
Life of Tire
The service life of a tire is dependent upon varying
factors including, but not limited to:
•Driving style
•Tire pressure
•Distance driven
WARNING!
Tires and the 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.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
“Tread Wear Indicators”). Refer to the “Tire and Loading
Information” 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.
298 STARTING AND OPERATING

FUEL REQUIREMENTS
GASOLINE ENGINES
Your vehicle is designed to meet all emis-
sion regulations and provide excellent fuel
economy when using high-quality regular
unleaded gasoline with an octane rating of
87. The use of premium gasoline is not
recommended. The use of premium gaso-
line will provide no benefit over high-quality regular
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 thesesymptoms, try another brand of gasoline (with the ap-
propriate octane rating for your engine) before consider-
ing service for the vehicle.
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
specifically blended to reduce vehicle emissions and
improve air quality.
The manufacturer supports the use of “reformulated
gasolines”. Properly blended “reformulated gasolines”
will provide excellent performance and durability of
engine and fuel system components.

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 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 emission control system.
•An out-of-tune engine, or certain fuel or ignition
malfunctions, can cause the catalytic converter tooverheat. 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.
•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.

HAZARD WARNING FLASHER
The flasher switch is located on the instrument
panel, below the radio. Depress the switch and
both cluster indicators and all front and rear
directional 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 ac-
tion.
•On the highways — Slow down.
•In city traffic — While stopped, put the transmission in
NEUTRAL, but do not increase engine idle speed.
If the pointer rises to theH(red) mark, the instrument
cluster will sound a chime. When safe, pull over and stop
the vehicle with the engine at idle. Turn off the air
conditioning and wait until the pointer drops back into
the normal range. If the pointer remains on theH(red)
mark for more than a minute, turn the engine off imme-
diately and call for service.
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
332 WHAT TO DO IN EMERGENCIES

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.
CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the temperature gauge reads “H”,
pull over when safe and stop the vehicle with the
engine at idle. Turn the air conditioner OFF and wait
until the pointer drops back into the normal range.
After appropriate action has been taken, if the
pointer remains on the “H”, 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 “Maintenance”, Section 7 of
this manual. Follow the warnings under the Cooling
System Pressure Cap paragraph.
AUTOMATIC TRANSAXLE OVERHEATING
During sustained high speed driving or trailer towing up
long grades on hot days, the automatic transaxle oil may
become too hot.
If this happens, the transmission overheat indi-
cator light will come on, and the vehicle will
slow slightly until the automatic transaxle cools
down enough to allow a return to the requested speed. If
the high speed is maintained, the overheating will reoccur,
as before, in a cyclic fashion.
