GENERAL MAINTENANCE
1. GENERAL NOTICE
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 performe\
d.
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 inter\
val (months).
Maintenance service after the last period should be performed at the same interval \
as before unless
otherwise noted.
Failure to do even one item can cause the engine to run poorly and incre\
ase exhaust emissions.
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 FULL and LOW lines on the se\
e −through reservoir.
4. RADIATOR AND HOSES
(a) Check that the front of the radiator is clean and not blocked with leave\
s, dirt or bugs.
(b) Check the hoses for cracks, kinks, rot or loose connections.
5. BATTERY ELECTROLYTE LEVEL
Check that the electrolyte level of all battery cells is between the upp\
er and lower level lines on the case.
If level is low, add distilled water only.
6. BRAKE FLUID LEVELS
Check that the brake fluid level is near the upper level line on the see\
−through reservoir.
7. ENGINE DRIVE BELTS
Check drive belt for fraying, cracks, wear or oiliness.
8. ENGINE OIL LEVEL
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 HOT or COLD range depending on the fluid temp\
erature.
10. AUTOMATIC 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 sel\
ector into all positions from the P to L, and then shift into the P.
(c) 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 HOT range.
(d) Do this check with the fluid at normal driving temperature (70 − 80°C (158 − 176° F)).
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.
11. 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 corrected.

CHASSIS
INSPECTION
1. INSPECT STEERING LINKAGE
(a) Check the steering linkage for looseness or damage.
Check that the tie rod ends do not have excessive
play.
Check that the boot clamps are not loose.
(b) Inspect the dust cover for damage.
2. INSPECT SRS AIRBAG (Driver airbag: See page RS−9 )
(Front passenger airbag: See page RS−23 )
3. INSPECT STEERING GEAR HOUSING OIL
Check the steering gear housing for oil leakage.
If leakage is found, check for cause and repair.
4. INSPECT OIL LEVEL IN AUTOMATIC TRANSMISSION
(See page DI−131 )
5. INSPECT OIL LEVEL IN TRANSFER AND DIFFEREN- TIAL
(a) Transfer: Remove the filler plug and feel inside the hole with your
finger. Check that the oil comes to within 5 mm (0.20 in.)
of the bottom edge of the hole.
If the level is low, add oil until it begins to run out of the filler hole.
Oil drade: API GL −4 or GL−5
Viscosity: 75W−90
(b) Differential: Remove the filler plug and feel inside the hole with your
finger. Check that the oil comes to within 5 mm (0.20 in.)
of the bottom edge of the hole.
If the level is low, add oil until it begins to run out of the filler hole.
Oil drade: Hypoid gear oil API GL −5
Viscosity:
Above −18°C (0° F) SAE 90
Below −18°C (0° F) SAE 80W−90 or 80W
6. REPLACE AUTOMATIC TRANSMISSION FLUID (See page DI−3)

PROBLEM SYMPTOMS TABLE
Use the table below to help you find the cause of the problem. The numbers \
indicate the priority of the likely
cause of the problem. Check each part in order. If necessary, replace these parts.
(w/ Differential locking system):
Check that center differential lock mode is set.
When switching differential Free↔Lock, the indicator lamp will blink if the gears of the differen-
tial lock sleeve are not meshed. If this occurs, when the tires are rotated \
to apply differential
power to the differential, the differential locks and the indicator lamp\
light up.

STEERING POWER STEERING FLUID
1996 LAND CRUISER (RM451U)
INSPECTION
1. CHECK FLUID LEVEL
(a) Keep the vehicle level.
(b) With the engine stopped, check the fluid level in the oil reservoir.
If necessary, add fluid.
Fluid: ATF DEXRON® II or III
HINT:
Check that the fluid level is within the HOT LEVEL range on the
reservoir cap dipstick. If the fluid is cold, check that it is within
the COLD LEVEL range.
(c) Start the engine and run it at idle.
(d) Turn the steering wheel from lock to lock several times to
boost fluid temperature.
Fluid temperature: 80° C (176°F)
(e) Check for foaming or emulsification.
If there is foaming or emulsification, bleed power steering sys-
tem. (See page SR−3 ).
(f) With the engine idling, measure the fluid level in the oil reservoir.
(g) Stop the engine.
(h) Wait a few minutes and remeasure the fluid level in the oil reservoir.
Maximum fluid level rise: 5 mm (0.20 in.)
If a problem is found, bleed power steering system (See page
SR−3 ).
(i) Check the fluid level.
