± INTRODUCTIONABBREVIATIONS USED IN THIS MANUALIN±37

18. BRAKE PEDAL
(a) Check that pedal for smooth operation.
(b) Check that the pedal has the proper reserve
distance and freeplay.
(c) Check the brake booster function.
19. BRAKES
At a safe place, check that the brakes do not
pull to one side when applied.
20. PARKING BRAKE
(a) Check that the pedal has the proper travel.
(b) On a safe incline, check that the vehicle is
held securely with only the parking brake
applied.
21. AUTOMATIC TRANSMISSION PARK
MECHANISM
(a) Check the lock release button of the selector
lever for proper and smooth operation.
(b) On a safe incline, check that the vehicle is
held securely with the selector lever in the ºPº
position and all brakes released.
UNDER HOOD
22. WINDSHIELD WASHER FLUID
Check that there is sufficient fluid in the tank.
23. ENGINE COOLANT LEVEL
Check that the coolant level is between the
LEVEL lines on the see±through reservoir at
normal temperature (20°C (68°F)).
24. 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.
25. BATTERY ELECTROLYTE LEVEL
Check the indicator.
When the indicator color is blue, the condition
is satisfactory. A red color indicates that dis-
tilled water must be added, and white indi-
cates that charging is necessary.
26. BRAKE FLUID LEVEL
Check that the brake fluid level is near the up-
per level line on the see±through reservoir.27. ENGINE DRIVE BELT
Check drive belt for fraying, cracks, wear or
oil contamination.
28. ENGINE OIL LEVEL
Check that level on the dipstick with the en-
gine turned off.
29. POWER STEERING FLUID LEVEL
Check the level on the dipstick.
The level should be in the ºHOTº or ºCOLDº
range depending on the fluid temperature.
30. A U TO M AT I C TRANSMISSION FLUID
LEVEL
(a) Park the vehicle on a level surface.
(b) With the engine idling and the parking and
foot brake applied, shift the selector into all
positions from ºPº to ºLº, and then shift into ºPº
position.
(c) Turn and pull out the dipstick and wipe off the
fluid with a clean rag.
Re±insert the dipstick fully and check that the
fluid level is in the ºHOTº range.
(d) Perform this check with the fluid at normal
driving temperature (70±80°C (158±176°F)).
If the level is at the low side, add fluid.
NOTICE: Do not overfill.
HINT: Wait about 30 minutes before checking
the fluid level after extended driving at high
speeds in hot weather, driving in heavy traffic
or with a trailer.
31. EXHAUST SYSTEM
Visually inspect for cracks, holes or loose
supports.
If any change in the sound of the exhaust or
smell of the exhaust fumes is noticed, have
the cause located and correted. MA±18

4. CHECK FOR FOAMING OR EMULSIFICATION
If there is foaming or emulsification, bleed power steering
system.
(See page SR±9)
5. CHECK FLUID LEVEL RISE
(a) With the engine idling, measure the fluid level in the reservoir.
(b) Stop the engine.
(c) Wait a few minutes and remeasure the fluid level in the
reservoir.

REPLACEMENT
1. JACK UP FRONT OF VEHICLE AND SUPPORT IT WITH
STANDS
2. DRAIN FLUID
(a) Disconnect the return hose from the PS vane pump.
(b) Turn the steering wheel from lock to lock.
3. FILL OIL RESERVOIR
(a) Fill oil reservoir with fresh fluid.
Fluid:
ATF DEXRON[ II
(b) Start engine.
(c) After 1 or 2 seconds, fluid will begin to discharge from the
return hose.
(d) Stop the engine immediately.
NOTICE: Take care that some fluid remains in the oil res-
ervoir.
(e) Repeat steps (a), (b), (c) and (d) until there is no more air in
fluid.
(f) Connect the return hose.

1. JACK UP FRONT OF VEHICLE AND SUPPORT IT WITH
STANDS
2. TURN STEERING WHEEL
With the engine stopped, turn the steering slowly from lock
to lock several times.
NOTICE: Take care that some fluid remains in the oil res-
ervoir.
3. LOWER VEHICLE
4. START ENGINE
Run the engine at idle for a few minutes.
5. TURN STEERING WHEEL
(a) With the engine at idling, turn the wheel to left or right full lock
and keep it there for 2±3 seconds, then turn the wheel to the
opposite full lock and keep it there for 2±3 seconds.
(b) Repeat (a) several times.
6. STOP ENGINE
7. CHECK FOR FOAMING OR EMULSIFICATION
If the system has to be bled twice specifically because of
foaming or emulsification, check for fluid leaks in the system.
