18. ACCELERATOR PEDAL
Check the pedal for smooth operation and uneven
pedal effort or catching.
19. CLUTCH PEDAL (See page CL±3)
Check the pedal for smooth operation.
Check that the pedal has the proper freeplay.
20. BRAKE PEDAL (See page BR±6)
(a) Check the pedal for smooth operation.
(b) Check that the pedal has the proper reserve
distance and freeplay.
(c) Check the brake booster function.
21. BRAKES
At a safe place, check that the brakes do not pull
to one side when applied.
22. PARKING BRAKE (See page BR±8)
(a) Check that the lever has the proper travel.
(b) On a safe incline, check that the vehicle is
held securely with only the parking brake
applied.
23. 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 vehicle is held
securely with the selector lever in the ºPº
position and all brakes released.
UNDER HOOD
24. WINDSHIELD WASHER FLUID
Check that there is sufficient fluid in the tank.
25. ENGINE COOLANT LEVEL
Check that the coolant level is between the
ºFULLº and ºLOWº lines on the see±through reser-
voir.
26. 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.
27. BATTERY ELECTROLYTE LEVEL
Check that the electrolyte level of all battery cells
is between the upper and lower level lines on the
case. If level is low, add distilled water only.28. BRAKE AND CLUTCH FLUID LEVELS
(a) Check that the brake fluid level is near the
upper level line on the see±through reser-
voir.
(b) Check that the clutch fluid level is within
+ 5 mm (0.20 in.) of the reservoir hem.
29. ENGINE DRIVE BELTS
Check all drive belts for fraying, cracks, wear or
oiliness.
30. ENGINE OIL LEVEL
Check the level on the dipstick with the engine
turned off.
31. POWER STEERING FLUID LEVEL
Check the level.
The level should be in the ºHOTº or ºCOLDº
range depending on the fluid temperature.
32. 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
positions from ºPº to ºLº, and then shift
into ºPº.
(c) Pull out the dipstick and wipe off the fluid
with a clean rag. Re±insert the dipstick
and check that the fluid level is in the HOT
range.
(d) Perform this check with the fluid at normal
driving temperature (70 ± 80
°C or
158 ± 176°F).
NOTE: Wait about 30 minutes before check-
ing the fluid level after extended driving at high
speeds i n hot weather, driving i n heavy traffic
or with a trailer.
33. EXHAUST SYSTEM
Visually inspect for cracks, holes or loose sup-
ports.
If any change in the sound of the exhaust oK
smell of the exhaust fumes is noticed, have the
cause located and corrected.
