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 5-14 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 5-38 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 5-60
for further details.
Cassette Tape Player Service
Clean cassette tape player. Cleaning should be done
every
50 hours of tape play. See Audio Systern(s)
on page 3-63 for further details.
At Least Twice a Year
Restraint System Check
:s , Make sure the safety belt reminder light and all your bell
buckles, latch plates, retractors and anchorages are
working properly. Look for any other loose or damaged
safety belt system parts.
If you see anything that might
keep a safety belt system from doing its
job, have it
repaired. Have any torn or frayed safety belts replaced.
6-1 0

Also look for any opened or broken air bag coverings,
and have them repaired or replaced. (The air bag
system does not need regular maintenance.)
Wiper Blade Check
Inspect wiper blades for wear or cracking. Replace
blade inserts that appear worn or damaged
or that
streak or miss areas of the windshield. Also see
Cleaning the Outside of Your Vehicle on page 5-90.
Spare Tire Check
At least twice a year, after the monthly inflation check of
the spare tire determines that the spare is inflated to
the correct tire inflation pressure, make sure that
the spare tire is stored securely. Push, pull, and then try
to rotate or turn the tire.
If it moves, use the folding
wrench to tighten the cable. See
Changing a Flat Tire
on page
5-70.
Weatherstrip Lubrication
Silicone grease on weatherstrips will make them last
longer, seal better, and not stick or squeak. Apply
silicone grease with a clean cloth. During very cold,
damp weather more frequent application may be
required. See
Part D: Recommended Fluids and
Lubricants on page
6-16.
Automatic Transaxle Check
Check the transaxle fluid level; add if needed. See
Automatic Transaxle Fluid on page 5-20. A fluid loss
may indicate a problem. Check the system and repair
if needed.
At Least Once a Year
Key Lock Cylinders Service
Lubricate the key lock cylinders with the lubricant
specified
in Part D.
Body Lubrication Service
Lubricate all key lock cylinders, hood latch assemblies,
secondary latches, pivots, spring anchor and release
pawl, hood and door hinges, rear folding seats, fuel door
hinge, liftgate hinges, power sliding door cable and
sliding door track(s). Part
D tells you what to use.
More frequent lubrication may be required when

When you are doing this check, the vGIlicle
could move suddenly.
If it does, you or others
could be injured. Follow the steps below.
1. Before you start, be sure you have enough room
around the vehicle.
2. Firmly apply both the parking brake and the regular
brake. See
Parking Brake on page 2-39 if necessary.
Do not use the accelerator pedal, and be ready to
turn
off the engine immediately if it starts.
3. Try to start the engine in each gear. The starter
should work only in PARK (P) or NEUTRAL (N).
If the starter works in any other position, your
vehicle needs service. When
you are doing this check, the vehicle
could move suddenly.
If it does, you or others
could be injured. Follow the steps below.
1.

3.
Before you start, be sure you have enough room
around the vehicle. It should be parked on a level
surface.
Firmly apply the parking brake. See
Parking Brake
on page 2-39
if necessary.
Be ready to apply the regular brake immediately
if the vehicle begins to move.
With the engine
off, turn the key to the RUN
position, but don’t start the engine. Without applying
the regular brake, try to move the shift lever out
of PARK (P) with normal effort. If the shift lever
moves out of PARK (P), your vehicle needs service.

When you are doing this check, your vehicle
could begin to move.
You or others could be
injured and property could be damaged. Make
sure there is room in front
of your vehicle in
case it begins to roll. Be ready to apply the
regular brake at once should the vehicle begin
I to move. I
Park on a fairly steep hill, with the vehicle facing
downhill. Keeping your foot on the regular brake,
set the parking brake.
e To check the parking brake’s holding ability: With
the engine running and transaxle
in NEUTRAL (N),
slowly remove foot pressure from the regular
brake pedal.
Do this until the vehicle is held by
the parking brake only.
To check the PARK (P) mechanism’s holding ability:
With the engine running, shift to PARK (P). Then
release the parking brake followed by the regular
brake.
Underbody Flushing Service
At least every spring, use plain water to flush any
corrosive materials from the underbody. Take care to
clean thoroughly any areas where mud and other debris
can collect,
6-1 3

Part C: Periodic Maintenance
Inspections
Listed in this part are inspections and services which
should be performed at least twice a year (for instance,
each spring and fall).
You should let your dealer’s
service department or other qualified service center
do these
jobs. Make sure any necessary repairs
are completed at once.
Proper procedures to perform these services may be
found in a service manual. See
Service Publications
Ordering Information on page
7- IO.
Steering, Suspension and Front
Drive
Axle Boot and Seal Inspection
Inspect the front and rear suspension and steering
system for damaged, loose or missing parts, signs of
wear or lack of lubrication. Inspect the power steering
lines and hoses for proper hook-up, binding, leaks,
cracks, chafing, etc. Clean and then inspect the drive
axle boot seals for damage, tears or leakage. Replace
seals
if necessary.
Exhaust System Inspection
Inspect the complete exhaust system. Inspect the body
near the exhaust system. Look for broken, damaged,
missing or out-of-position parts as well as open seams,
holes, loose connections or other conditions which
could cause a heat build-up in the floor pan or could let
exhaust fumes into the vehicle. See
Engine Exhaust
on page
2-43.
Fuel System Inspection
Inspect the complete fuel system for damage or leaks.
Engine Cooling System Inspection
Inspect the hoses and have them replaced if they
are cracked, swollen or deteriorated. Inspect all pipes,
fittings and clamps; replace as needed. Clean the
outside of the radiator and air conditioning condenser.
To help ensure proper operation, a pressure test of
the cooling system and pressure cap is recommended
at least once a year.
6-1 4

Throttle System Inspection
Inspect the throttle system for interference or binding,
and for damaged or missing parts. Replace parts
as needed. Replace any components that have high
effort or excessive wear.
Do not lubricate accelerator
and cruise control cables.
Transfer Case (Power Transfer Unit)
and Carrier Assembly-Differential
(Rear Drive Module) All-Wheel Drive
Inspection
Every 12 months or at engine oil change intervals,
check rear differential and transfer case and add
lubricant when necessary.
A fluid loss could indicate
a problem; check and have it repaired,
if needed.
Check vent hoses at transfer case and differential 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.
