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.
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.
When rotating your tires, always use the correct rotation
pattern shown here.
Don’t include
the compact spare tire in your tire rotation.

Maintenance Schedule
I Short Trip/City Definition I
Follow the Short Trip/City 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 you should follow this schedule if
you operate your vehicle under any of these conditions
is that these conditions cause engine oil to break
down sooner.
Short Trip/City Intervals
Every 3,000 Miles (5 000 km): Engine Oil and Filter
Change (or
3 months, whichever occurs first).
(or
6 months, whichever occurs first). Tire Rotation.
Every 6,000 Miles (10 000 km): Chassis Lubrication
Every 30,000 Miles (50 000 km): Air Cleaner Filter
Replacement. Throttle Body Bore and Valve Plates
Inspection. Fuel Tank, Cap and Lines Inspection.
Service (severe conditions only).
Every 50,000 Miles (83 000 km): Automatic Transaxle
Every 60,000 Miles (100 000 km): Engine Accessory
Every 100,000 Miles (166 000 km): Spark Plug Wire
Every 150,000 Miles (240 000 km): Cooling System
Drive Belt
Inspection.
Inspection. Spark Plug Replacement.
Service (or every
60 months, whichever occurs first).
These intervals only summarize maintenance services.
Be sure
to follow the complete maintenance schedule on
the following pages.

Maintenance Schedule
I Long Trip/Highway Definition I
Follow this maintenance schedule only if none of the
conditions from the Short Trip/City Maintenance
Schedule is true.
Do not use this schedule if the vehicle
is used
for trailer towing, driven in a dusty area or used
off paved roads. Use the Short Trip/City schedule for
these conditions.
Driving a vehicle with a fully warmed engine under
highway conditions causes engine oil to break
down slower.
Long Trip/Highway Intervals
1
Every 7,500 Miles (12 500 km): Engine Oil and Filter
Change (or every
12 months, whichever occurs first).
Chassis Lubrication (or every
12 months, whichever
occurs first). Tire Rotation.
Every 30,000 Miles (50 000 km): Throttle Body Bore
and Valve Plates Inspection. Air Cleaner Filter
Replacement. Fuel Tank, Cap and Lines Inspection.
Every 50,000 Miles (83 000 km): Automatic Transaxle
Every 60,000 Miles (100 000 km): Engine Accessory
Service (severe conditions
only).
Drive Belt Inspection.
Every 100,000 Miles (166 000 km): Spark Plug Wire
Every 150,000 Miles (240 000 km): Cooling System
Inspection. Spark Plug Replacement.
Service
(or every 60 months, whichever occurs first).
These intervals only summarize maintenance services.
Be sure
to follow the complete maintenance schedule on
the following pages.

Short TripKity Maintenance Schedule
The services shown in this schedule up to 100,000 miles
(166
000 krn) should be performed after 100,000 miles
(166
000 km) at the same intervals. The services shown
at 150,000 miles (240
000 km) should be performed at
the same interval after 150,000 miles (240
000 km).
See “Owner Checks and Services” and “Periodic
Maintenance Inspections” following.
Footnotes
-f The U.S. Environmental Protection Agency or the
California Air Resources Board has determined that the
failure to perform this maintenance item will not nullify
the emission warranty or limit recall liability prior to the
completion of the vehicle’s useful life. We, however,
urge that all recommended maintenance services be
performed at the indicated intervals and the maintenance
be recorded.
# Lubricate the suspension and steering linkage,
transaxle shift linkage, parking brake cable guides and
underbody contact points and linkage.
* Your vehicle has an Engine Oil Life Monitor. This
monitor will show
you when to change the oil -- usually
between
3,000 miles (5 000 km) and 7,500 miles
(12
500 km) since your last oil change. Under severe
conditions, the indicator may come on before
3,000 miles (5 000 km). Never drive your vehicle
more than
7,500 miles (12 500 krn) or 12 months,
(whichever occurs first), without an oil change.
The system won’t detect dust in the oil.
So if you
drive in a dusty area be sure to change your oil every
3,000 miles (5 000 km) or sooner if the CHANGE OIL
light comes on. Remember to reset the Oil Life Monitor
when the oil has been changed. For more information, see “Engine Oil Life Monitor” in the Index.
+ A good time to check your brakes is during tire
rotation. See “Brake System Inspection’’ under “Periodic
Maintenance Inspection” in Part
C of this schedule.
