B HOW TO USE THIS MANUAL
The ground points circuit diagram shows the connections from all major parts to the respective ground points. When
troubleshooting a faulty ground point, checking the system circuits which use a common ground may help you identify
the problem ground quickly. The relationship between ground points (
EA, IB and IC shown below) can also be
checked this way.

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 serice 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
otherwise noted.
2. WINDSHIELD WASHER FLUID
Check that there is sufficient fluid in the tank.
3. ENGINE COOLANT LEVEL
Check that the coolant level is between the ºFULLº and ºLOWº lines on the see±through reservoir.
4. RADIATOR AND HOSES
(a) Check that the front of the radiator is clean and not blocked with leaves, dirt or bugs.
(b) Check the hoses for cracks, kinks, rot or loose connections.
5. BRAKE FLUID LEVELS
Check that the brake fluid levels are near the upper level line on the see±through reservoirs.
6. CHECK TRANSAXLE OIL (FLUID)

Visually check the transaxle for oil (fluid) leakage.

If leakage is found, check for the cause and repair.
HINT:
Wait until the engine and motor cools down (approx. 30 min.) before checking the fluid level after extended
driving at high speeds, in hot weather, in heavy traffic or pulling a trailer.

(b) Using needle±nose pliers, disconnect the parking brake
cable from the parking brake lever, and remove the rear
shoe.
6. REMOVE PARKING BRAKE LEVER
(a) Remove the C±washer.
(b) Remove the parking brake lever from the rear shoe.
7. REMOVE WHEEL CYLINDER
(a) Using SST, disconnect the brake line. Use container to
catch the brake fluid.

When wiper switch is in HI position, the wiper blade is in contact
with the body.

When the wiper switch is OFF, the wiper blade does not retract
or the retract position is wrong.
