Two labels on your vehicle show how much weight it
may properly carry. The Tire-Loading Information
label found on the rear edge of the driver's door tells
you the proper size. speed ratinu and recommended
inflation pressures for the tires on your vehicle. It also
gives you important information about the number
of people that can be in your vehicle and the total weight
that you can carry. This weight is called the Vehicle
Capacity Weight, and includes the weight of all
occUpanfs, cargo and nonfac~ory~~ns~a~~e~ options.

The other label is the Certification label, found

weight of the vehicle, all occupants, fuel and cargo.
Never exceed the GVWR for your vehicle, or the Gross

Inflation -- Tire Pressure
The Tire-Loading Information label, which is on the rear
edge of the driver’s door, shows the correct inflation
pressures for your tires when they’re cold. “Cold” means
your vehicle has been sitting for at least three hours
or driven no more than
1 mile (1.6 km).
Notice: Don’t let anyone tell you that underinflation
or overinflation is
all right. It’s not. If your tires
don’t have enough air (underinflation), you can get
the following:
Too much flexing
0 Too much heat
Tire overloading
Bad wear
@ Bad handling
0 Bad fuel economy
If your tires have too much air (overinflation), you
can get the following:
0 Unusual wear
Bad handling
Rough ride
0 Needless damage from road hazards
When to Check
Check your tires once a month or more.
Don’t forget your compact spare tire.
It should be at
60 psi (420 kPa).
How to Check
Use a good quality pocket-type gage to check tire
pressure. You can’t tell
if your tires are properly inflated
simply by looking at them. Radial tires may look
properly inflated even when they’re underinflated.
Be sure to put the valve caps back on the valve stems.
They help prevent leaks by keeping out dirt and
moisture.
5-54

Tire Inspection and Rotation
Tires should be rotated every 7,500 miles (12 500 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 Is Time
for New Tires on page 5-56
and Wheel Replacement
on page 5-59
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 “Part A: Scheduled
Maintenance Services” in Section
6, for scheduled
rotation intervals.
n 4 J
1
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” under
Capacities and
Specifications on page 5-86.
.
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 ciorh 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.
5-55

Compact Spare Tire
Although the compact spare tire was fully inflated when
your vehicle was new, it can lose air after
a time.
Check the inflation pressure regularly. It should be
60 psi (420 kPa).
After installing the compact spare on your vehicie, you
should stop as soon as possible and make sure
your spare tire is correctly inflated. The compact spare
is made to perform well at speeds up
to 65 mph
(105 km/h) for distances up to 3,000 miles (5 000 km),
so you can finish your trip and have your full-size
tire repaired or replaced where you want. Of course, it’s
best
to replace your spare with a full-size tire as
soon as you can. Your spare will last longer and be in
good shape in case you need it again.
Notice: When the compact spare is installed, don’t
take your vehicle through an automatic car wash
with guide rails. The compact spare can get caught
on the rails. That can damage the tire and wheel,
and maybe other parts
of your vehicle.
Don’t use your compact spare on other vehicles.
And don’t mix your compact spare tire or wheel with
other wheels or tires. They won’t fit. Keep your spare tire
and its wheel together.
Notice: Tire chains won’t fit your compact spare.
Using them can damage your vehicle and can
damage the chains too. Don’t use tire chains on
your compact spare.

Part B: Owner Checks and Services
Listed in this part 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
perform 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 on page 5-15 for further
details.
Engine Coolant Level Check
Check the engine coolant level and add DEX-COOL@
coolant mixture
if necessary. See Engine Coolant
on page 5-23
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 on page 5-37 for further
details.
At Least Once a Month
Tire Inflation Check
Make sure tries are inflated to the correct pressures.
Don’t forget
to check your spare tire. See Tires on
page 5-53
for further details.
Cassette Deck Service
Clean cassette deck. Cleaning sholdd be done every
50 hours of tape play. See Audio System(s) on
page 3-38
for further details.
