Defroster
Check operation by selecting the defrost mode and place
the blower control on high speed. You should be able to
feel the air directed against the windshield. See your
authorized dealer for service if your defroster is inoper-
able.
Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread. Inspect the tread and sidewall for
cuts and cracks. Check the wheel nuts for tightness.
Check the tires (including spare) for proper pressure.
Lights
Have someone observe the operation of exterior lights
while you work the controls. Check turn signal and high
beam indicator lights on the instrument panel.
Door Latches
Check for positive closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for fuel,
engine coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel, power steering fluid, or
brake fluid leaks are suspected, the cause should be
located and corrected immediately.
82 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

13. Oil Pressure Warning Light
This light shows low engine oil pressure. The light
will turn on and remain on when the ignition
switch is turned from the LOCK or ACC position to the
ON position. The light will turn off after the engine is
started. If the light does not turn on during starting, have
the system checked by an authorized dealer.
If the light turns on and remains on while driving, safely
bring the vehicle to a stop and shut off the engine. DO
NOT OPERATE THE VEHICLE UNTIL THE CAUSE IS
CORRECTED.
This light does not show the quantity of oil in the engine.
The engine oil level must be checked using the proper
procedure. (See page 403 for more information.)
14. Anti-Lock Brake Warning Light
This light monitors the Anti-Lock Brake Sys-
tem. This light will turn on when the ignition
switch is turned to the ON position and it may
stay on for approximately 3 seconds.If the light remains on or turns on during 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, provided 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 benefit of Anti-Lock Brakes.
The ABS Warning light should be checked frequently to
assure that it is operating properly. Turn the ignition
switch to the ON position, but do not start the vehicle.
The light should turn on. If the light does not turn on,
have the system checked by an authorized dealer. (See
page 310 for more information.)
15. Tachometer
This gauge measures engine revolutions-per-minute
(rpm x 1000). Before the pointer reaches the red area, ease
up on the accelerator to prevent engine damage.

NOTE:As the coolant temperature gauge approaches
9H,9this indicator will illuminate and a single chime will
sound. Further overheating will cause the temperature
gauge to pass9H.9In this case, the indicator will flash
continuously and a continuous chime will sound, until
the engine is allowed to cool.
CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the temperature gauge reads ªH,º
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 ªH,º and you hear continuous chimes, 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 of this manual. Follow
the warnings under the Cooling System Pressure Cap
paragraph.
23. Coolant Temperature Gauge
The temperature gauge indicates engine coolant tem-
perature. Any reading within the normal range indicates
that the cooling system is operating satisfactorily. The
gauge pointer will likely indicate a high temperature
when driving in hot weather, up mountain grades, in
heavy traffic, or when towing a trailer. If the pointer rises
to the ªHº mark, safely pull over and stop the vehicle. If

Oil Change Required
Your vehicle is equipped with an engine oil change
indicator system. The ªOil Change Requiredº message
will flash in the EVIC display for approximately 10
seconds after a single chime has sounded to indicate the
next scheduled oil change interval. The engine oil change
indicator system is duty cycle based, which means the
engine oil change interval may fluctuate dependent upon
your personal driving style.

Life of Tire
The service life of a tire is dependent upon varying
factors including but not limited to:
²Driving style
²Tire pressure
²Distance 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.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.
342 STARTING AND OPERATING

These items should be inspected if a malfunction is
observed or suspected.
Engine Oil
Checking Oil Level
To assure proper engine lubrication, the engine oil must
be maintained at the correct level.
The best time to check the engine oil level is about 5
minutes after a fully warmed up engine is shut off or
before starting the engine after it has sat overnight.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Always
maintain the oil level within the SAFE zone on the
dipstick. Adding one quart of oil when the reading is at
the bottom of the SAFE zone will result in a reading at the
top of the safe zone on these engines.
CAUTION!
Do not overfill the engine. Overfilling the engine
will cause oil aeration, which can lead to loss of oil
pressure and an increase in oil temperature. This
could damage your engine. Also, be sure the oil fill
cap is replaced and tightened after adding oil.

Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically.
Suggested service intervals can be found in the ªMainte-
nance Scheduleº in Section 8 of this manual.
WARNING!
Riding the brakes can lead to brake failure and
possibly an accident. Driving with your foot resting
or riding on the brake pedal can result in abnormally
high brake temperatures, excessive lining wear, and
possible brake damage. You wouldn't have your full
braking capacity in an emergency.
Brake and Power Steering System Hoses
When servicing the vehicle for scheduled maintenance,
inspect the surface of the hoses and nylon tubing for
evidence of heat and mechanical damage. Hard andbrittle rubber, cracking, tears, cuts, abrasions, and exces-
sive swelling suggest deterioration of the rubber. Particu-
lar attention should be made to examining those hose
surfaces nearest to high heat sources, such as the exhaust
manifold.
Insure nylon tubing in these areas has not melted or
collapsed.
Inspect all hose clamps and couplings to make sure they
are secure and no leaks are present.
NOTE:
²Often, fluids such as oil, power steering fluid, and
brake fluid are used during assembly plant operations
to ease the assembly of hoses to couplings. Therefore,
oil wetness at the hose-coupling area is not necessarily
an indication of leakage. Actual dripping of hot fluid
when systems are under pressure (during vehicle
operation) should be noted before a hose is replaced
based on leakage.
422 MAINTAINING YOUR VEHICLE

Once a Month
²Check tire pressure and look for unusual wear or
damage.
²Inspect the battery and clean and tighten the terminals
as required.
²Check the fluid levels of coolant reservoir, brake
master cylinder, and power steering, and add as
needed.
²Check all lights and other electrical items for correct
operation.At Each Oil Change
²Change the engine oil filter.
²Inspect the brake hoses and lines.
²Check the manual transmission fluid level.
CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.
