Tire Pressure Monitor System (If Equipped)
The tire pressure monitor system can alert you to a large
change in the pressure
of one tire. The system “learns”
the pressure at each tire throughout the operating speed
range of your vehicle. The system normally takes
between
45 and 90 minutes of driving to learn the tire
pressures. This time may be longer depending on your
individual driving habits. Learning need not be
accumulated during
a single trip. Once learned, the
system will remember the tire pressures until the system
is recalibrated.
After the system has learned tire pressures with properly
inflated tires, the LOW TIRE light will come on if the
pressure in
one tire becomes 12 psi (83 kPa) lower than
the other three tires. The tire pressure monitor system
won’t alert you if the pressure
in more than one tire is
low, if the system is not properly calibrated, or if the
vehicle
is moving faster than 70 mph (1 10 kdh).
The tire pressure monitor system detects differences
in tire rotation speeds that are caused by changes
in
tire pressure. The system can alert you about a low
tire
-- but it doesn’t replace normal tire maintenance.
See “Tires” in the Index. When the LOW
TIRE light comes
on, you should stop
as soon as you can and check all your tires for damage.
(If a tire is flat, see “If
a Tire Goes Flat” in the Index.)
Also check
the tire pressure in all four tires as soon as
you can. See “Inflation
- Tire Pressure” in the Index.
The light will come on and stay on
until you turn off the
ignition or press the
RESET button.
Don’t reset the tire pressure monitor system without first
correcting the cause of the problem and checking and
adjusting the pressure in all four tires. If you reset the
system when the tire pressures are incorrect, the tire
pressure monitor system will not work properly and may
not alert you when
a tire is low.
Any time
you adjust a tire’s pressure, rotate your tires,
or have one or more tires repaired or replaced, you’ll
need to reset (calibrate) the tire pressure monitor system.
You’ll also need to reset the system whenever you buy
new tires and whenever the vehicle’s battery has been
disconnected.
To reset (calibrate) the system,
turn the ignition switch
to
RUN. Then press and hold the RESET button for
about five seconds.

The red RESET button is
located inside your
instrument panel fuse block.
(It’s the first button in the
top row of the fuse block.)
The LOW TIRE light will come
on and flash three
times. Then it will go off. If the light doesn’t go off, see
your dealer for service.
The system completes the calibration process during driving.
The system normally takes
15 to 20 minutes of driving in
each of three speed ranges to “learn” tire pressures. The
speed ranges are 15 to 40 mph (25 to 65 km/h), 40 to
65 mph (65 to 105 km/h) and above 65 mph (105 km/h).
When learning is complete, the system will alert you after
2-8 minutes if a tire is 12 psi (83 kPa) different from the
other
three tires. Detection thresholds may be higher and
detection times may be longer on rough roads, curves and
at high speeds. The system
is not capable of detection at
speeds greater
than 70 mph (1 10 km/h).
Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
(10 000 to 13 000 km). Any time you notice unusual
wear, rotate your tires
as soon as possible and check
wheel alignment. Also check for damaged tires or
wheels. See “When It’s Time for New Tires”
and
“Wheel Replacement” later in this section for
more information.
The purpose
of regular rotation is to achieve more
uniform wear for
all tires on the vehicle. The first
rotation is the most important. See “Scheduled
Maintenance Services”
in the Index for scheduled
rotation intervals.

ProCarManuals.com

When rotating your tires, always use the correct
rotation pattern shown here.
Don’t include the compact spare tire in your
tire rotation.
After the tires have been rotated, adjust the front and
rear inflation pressures
as shown on the Tire-Loading
Information label. Make certain that all wheel nuts are
properly tightened. See “Wheel Nut Torque”
in
the Index.
Rust or dirt on a wheel, or on the parts to which
it is fastened, can make wheel nuts become loose
after
a time. The wheel could come off and cause
an accident. When
you change a wheel, remove
any rust or dirt from places where the wheel
attaches to the vehicle. In an emergency, you can
use a cloth or
a paper towel to do this; but be
sure to use a scraper or wire brush later,
if you
need to,
to get all the rust or dirt off. (See
“Changing a Flat, Tire” in the Index.)
When It’s Time for New Tires
11 One way to tell when it’s
time for new tires is to
check the treadwear
indicators, which will
appear when your tires have
only
1/16 inch (1.6 mm) or
less of tread remaining.
You need a new tire if any of the following statements
are true:
0 You can see the indicators at three or more places
around the tire.
0 You can see cord or fabric showing through the
tire’s rubber.
0 The tread or sidewall is cracked, cut or snagged deep
enough to show cord or fabric.

Part B: Owner Checks and Services
Listed below are owner checks and services which
should be performed at the intervals specified to help
ensure the safety, dependability and emission control
performance of
your vehicle.
Be sure any necessary repairs are completed at once.
Whenever any fluids or lubricants are added to your
vehicle, make sure they are the proper ones, as shown
in Part
D.
At Each Fuel Fill
It is important for you or a service station attendant to
peform these underhood checks at each fuel
fill.
Engine Oil Level Check
Check the engine oil level and add the proper oil if
necessary. See “Engine Oil” in the Index for
further details.
Engine Coolant Level Check
Check the engine coolant level and add DEX-COOL’
coolant mixture if necessary.
See “Engine Coolant” in
the Index for further details.
Windshield Washer Fluid Level Check
Check the windshield washer fluid level in the
windshield washer tank and add the proper fluid if
necessary. See “Windshield Washer Fluid” in the Index
for further details.
At Least Once a Month
Tire Inflation Check
Make sure tires are inflated to the correct pressures. See
“Tires”
in the Index for further details.
Cassette Deck Service
Clean cassette deck. Cleaning should be done every
50 hours of tape play. See “Audio Systems” in the
Index for further details.
