1) Check universal joint and spline of propeller shaft for 

rattle. If rattle is found, replace defective part with a 
new one.

2) Check propeller shaft (front and rear) flange yoke 

bolts for tightness, and retighten them as necessary.
Refer to “Tightening Torque Specifications in Section

Manual Transmission Oil Inspection

S6JB0B0206028

1) Inspect transmission case for evidence of oil 

leakage. Repair leaky point if any.

2) Make sure that vehicle is placed level for oil level 

check.

3) Remove level / filler plug (1) of transmission.
4) Check oil level.

Oil level can be checked roughly by means of level 
plug hole. That is, if oil flows out of level plug hole or 
if oil level is found up to hole when level / filler plug is 
removed, oil is properly filled.
If oil is found insufficient, pour specified amount of 
specified oil.

5) Tighten level / filler plug to specified torque referring 

to “Manual Transmission Oil Change in Section 5B”.

Manual Transmission Oil Change

S6JB0B0206029

Change transmission oil with new specified oil referring 
to “Manual Transmission Oil Change in Section 5B”.

Automatic Transmission Fluid Inspection

S6JB0B0206030

1) Inspect transmission case for evidence of fluid 

leakage. Repair leaky point, if any.

2) Make sure that vehicle is placed level for fluid level 

check.

3) Check fluid level referring to “A/T Fluid Level Check 

in Section 5A”. If fluid level is low, replenish specified 
fluid.

Automatic Transmission Fluid Change

S6JB0B0206031

1) Inspect transmission case for evidence of fluid 

leakage. Repair leaky point, if any.

2) Make sure that vehicle is placed level for oil level 

check.

3) Remove level / filler plug of differentials (front and/or 

rear) and check oil level.
Oil level can be checked roughly by means of level 
plug hole. That is, if oil flows out of level plug hole or 
if oil level is found up to hole when level / filler plug is 
removed, oil is properly filled.
If oil is found insufficient, pour specified amount of 
specified oil.

4) Tighten level plug to specified torque.

For front differential, refer to “Front Differential Oil

new specified oil respectively.
For transfer, refer to “Transfer Oil Change in Section 
3C”.
For front differential, refer to “Front Differential Oil 
Change: Front in Section 3B”.
For rear differential, refer to “Rear Differential Oil 
Change: Rear in Section 3B”.

2) Check fluid level with engine stopped. If it is lower 

than LOWER level line, fill fluid up to UPPER level 
line.

NOTE
Fluid level should be checked when fluid is 
cool.

 

3) Visually check pump drive belt for cracks and wear 

and tension, referring to “P/S Pump and A/C 
Compressor (If Equipped) Drive Belt Inspection and 
Adjustment in Section 6C”.
If necessary, Adjust or replace it.

WARNING

!

 

Before performing the following check, be 
sure to have enough room around the 
vehicle. Then, firmly apply both the parking 
brake and the regular brakes. Do not use the 
accelerator pedal. If the engine starts, be 
ready to turn off the ignition promptly. Take 
these precautions because the vehicle could 
move without warning and possibly cause 
personal injury or property damage.

 

On A/T vehicles, try to start the engine in each select 
lever position. The starting motor should crank only in 
“P” (Park) or “N” (Neutral).
On M/T vehicles, place the shift lever in “Neutral,” 
depress clutch pedal fully and try to start.

WARNING

!

 

With vehicle parked on a fairly steep slope, 
make sure nothing is in the way downhill to 
avoid any personal injury or property 
damage. Be prepared to apply regular brake 
quickly even if vehicle should start to move.

are free from abnormal noise and abnormal vibration or 
any other abnormal condition.

Meters and Gauge
Check that speedometer, odometer, fuel meter, 
temperature gauge, etc. are operating accurately.

Lights
Check that all lights operate properly.

Windshield Defroster
Periodically check that air comes out from defroster 
outlet when operating heater or air conditioning.
