Tire Inspection and Rotation
Tires should be inspected every 6,000 to 8,000 miles
(10 000 to 13 000 km) for any signs of unusual wear.
If unusual wear is present, 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. 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
CertificatiodTire label. Make certain that all wheel nuts
are properly tightened. See “Wheel
Nut Torque” in
the Index.
’ A CAUTIO1
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.)

Maintenance Schedule
Short TripKity Definition
Follow the Short TripKity Maintenance Schedule if any
one
of these conditions is true for your vehicle:
0
0
0
0
0
Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such
as frequent
driving in stop-and-go traffic).
Most trips are through dusty areas.
You frequently tow a trailer or use a carrier on top of
your vehicle.
If the vehicle is used for delivery service, police, taxi
or other commercial application.
One of the reasons yo~l should follow this schedule if
you operate your vehicle under any of these conditions
is
that these conditions cause engine oil to break
down soonex

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
perform these underhood checks at each
filelfill.
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 the proper
coolant mix 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.
7-41

Drive Axle Service
Check readfront axle fluid level and add as needed.
Check constant velocity joints and axle
seals for leaking.
Transfer Case (All-Wheel Drive) Inspection
Every 12 months or at oil change intervals, check front
axle and transfer case and add lubricant when necessary.
Oil the control lever pivot point and all exposed control
linkage. Check vent hose at transfer case for kinks and
proper installation.
Brake System Inspection
Inspect the complete system. Inspect brake lines and
hoses for proper hook-up, binding, leaks, cracks,
chafing, etc. Inspect disc brake pads for wear and rotors
for surface condition. Also inspect drum brake linings
for wear and cracks. Inspect other brake parts, including
drums, wheel cylinders, calipers, parking brake, etc.
Check parking brake adjustment.
You may need to have
your brakes inspected more often if your driving habits
or conditions result in frequent braking.
