Footnotes
†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.
+A good time to check your brakes is during tire

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 to perform these underhood checks
at each fuel fill.
Engine Oil Level Check
Notice:It is important to check the engine oil
regularly and keep it at the proper level. Failure to
keep the engine oil at the proper level can cause
damage to the engine not covered by your warranty.
Check the engine oil level and add the proper oil if
necessary. SeeEngine Oil on page 5-13.
Engine Coolant Level Check
Check the engine coolant level and add DEX-COOL®
coolant mixture if necessary. SeeEngine Coolant
on page 5-22.
Windshield Washer Fluid Level Check
Check the windshield washer fluid level in the windshield
washer fluid reservoir and add the proper fluid if
necessary.
At Least Once a Month
Tire Ination Check
Inspect the tires and make sure the tires are inflated to
the correct pressures. Do not forget to check the spare
tire. SeeInflation - Tire Pressure on page 5-57.
At Least Twice a Year
Restraint System Check
Make sure the safety belt reminder light and safety belt
assemblies 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. Also seeChecking the Restraint
Systems on page 1-72.
6-18

Wiper Blade Check
Inspect wiper blades for wear, cracking, or
contamination. Clean the windshield and wiper blades,
if contaminated. Replace wiper blades that are worn
or damaged. SeeWindshield Wiper Blade Replacement
on page 5-49andWindshield and Wiper Blades on
page 5-84for more information.
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. SeePart D: Recommended Fluids and
Lubricants on page 6-23.
Manual Transmission Check
It is not necessary to check the transmission fluid level.
Check for leaks. A fluid leak is the only reason for fluid
loss. Have the system inspected and repaired if needed.
Automatic Transmission Check
Check the transmission fluid level; add if needed.
A fluid loss may indicate a problem. Check the
system and repair if needed.
Hydraulic Clutch System Check
Check the fluid level in the brake/clutch reservoir.
SeeHydraulic Clutch on page 5-21. A fluid loss in
this system could indicate a problem. Have the
system inspected and repaired at once.
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 hood latch assemblies, secondary latch,
pivots, spring anchor, release pawl, hood and body
door hinges, rear compartment, and any folding
seat hardware. Part D tells you what to use.
More frequent lubrication may be required when
exposed to a corrosive environment.
6-19

Starter Switch Check
{CAUTION:
When you are doing this inspection, the
vehicle could move suddenly. If the vehicle
moves, you or others could be injured.
1. Before you start, be sure you have enough room
around the vehicle.
2. Firmly apply both the parking brake and the regular
brake. SeeParking Brake on page 2-26if necessary.
Do not use the accelerator pedal, and be ready to
turn off the engine immediately if it starts.
3. On automatic transmission vehicles, 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.
On manual transmission vehicles, put the shift lever
in NEUTRAL, push the clutch pedal down halfway
and try to start the engine. The starter should
work only when the clutch pedal is pushed down
all the way to the floor. If the starter works when the
clutch pedal is not pushed all the way down, your
vehicle needs service.
Automatic Transmission Shift Lock
Control System Check
{CAUTION:
When you are doing this inspection, the
vehicle could move suddenly. If the vehicle
moves, you or others could be injured.
1. Before you start, be sure you have enough room
around the vehicle. It should be parked on a level
surface.
2. Firmly apply the parking brake. SeeParking Brake
on page 2-26if necessary.
Be ready to apply the regular brake immediately
if the vehicle begins to move.
3. With the engine off, turn the ignition to ON/RUN,
but do not 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.
