GENERAL MAINTENANCE
1. GENERAL NOTES
Maintenance items may vary from country to country. Check the owner's manual supplement in which
the maintenance schedule is shown.
Every service item in the periodic maintenance schedule must be performed.
Periodic maintenance service must be performed according to whichever interval in the periodic main-
tenance schedule occurs first, the odometer reading (miles) or the time interval (months).
Maintenance service after the last period should be performed at the same interval as before unless
noted.
Failure to do even one of the items can cause the engine to run poorly and/or increase the exhaust
emissions.
2. WINDSHIELD WASHER FLUID
(a) Check that there is sufficient fluid in the tank.
3. ENGINE COOLANT LEVEL
(a) Check that the coolant level is between the LEVEL lines on the see-through reservoir at normal tem-
perature (20°C (68°F)).
4. RADIATOR AND HOSES
(a) Check that the front of the radiator is clean and not blocked by leaves, dirt or bugs.
(b) Check the hoses for cracks, kinks, rot or loose connections.
5. BATTERY ELECTROLYTE LEVEL
(a) Check the indicator.
(b) Check that the electrolyte level of all the battery cells is between the upper and lower level lines on
the case.
6. BRAKE FLUID LEVEL
(a) Check that the brake fluid levels are near the upper level line on the see-through reservoirs.
7. ENGINE DRIVE BELT
(a) Check the drive belt for fraying, cracks, wear or oiliness.
8. ENGINE OIL LEVEL
(a) Check the level on the dipstick with the engine turned off.
9. POWER STEERING FLUID LEVEL
(a) Check the level on the dipstick.
(b) The level should be in the ºHOTº or ºCOLDº range depending on the fluid temperature.
10. AUTOMATIC TRANSMISSION FLUID LEVEL
(a) Park the vehicle on a level surface.
(b) With the engine idling and the parking brake applied, shift the selector into all the positions from ºPº
to ºLº, and then shift into the ºPº position.
(c) Pull out the dipstick and wipe off the fluid with a clean shop rag. Re-insert the dipstick and check that
the fluid level is in the ºHOTº range.
(d) Perform this check with the fluid at the normal driving temperature (70 to 80°C, 158 to 176°F).
HINT:
Wait until the engine cools down (approx. 30 min.) before checking the fluid level after extended driving at
high speed, in hot weather, in heavy traffic or after pulling a trailer.
11. EXHAUST SYSTEM
(a) Visually inspect for cracks, holes or loose supports.
If any change in the sound of the exhaust or the smell of the exhaust fumes is noticed, locate and correct
the cause.

CUSTOMER PROBLEM ANALYSIS
HINT:
In troubleshooting, the problem symptoms must be confirmed accurately. Preconceptions should be
discarded in order to give an accurate judgement. To clearly understand what the problem symptoms
are, it is extremely important to ask the customer about the problem and the conditions at the time it
occurred.
As much information as possible should be gathered for reference. Past problems that seem unrelated
may also help in some cases. In the Diagnostic section, a customer problem analysis table is provided
for each system.
5 items are important points in the problem analysis:
