GENERAL – How to Use This Manual00-4
EXPLANATION OF MANUAL CONTENTS
Indicates procedures to be performed
before the work in that section is started,
and procedures to be performed after
the work in that section is finished.
Indicates (by symbols) where lubrica-
tion is necessary.
Maintenance and Servicing Procedures
The numbers provided within the diagram indi-
cate the sequence for maintenance and servic-
ing procedures.
Removal steps:
The part designation number corresponds
to the number in the illustration to indicate
removal steps.
Disassembly steps:
The part designation number corresponds
to the number in the illustration to indicate
disassembly steps.Installation steps:
Specified in case installation is impossible
in reverse order of removal steps. Omitted
if installation is possible in reverse order of
removal steps.
Reassembly steps:
Specified in case reassembly is impossible
in reverse order of disassembly steps.
Omitted if reassemby is possible in reverse
order of disassembly steps.
Classifications of Major Maintenance/Service Points
When there are major points relative to maintenance and servicing procedures
(such as essential maintenance and service points, maintenance and service stan-
dard values, information regarding the use of special tools, etc.), these are ar-
ranged together as major maintenance and service points and explained in detail.
A: Indicates that there are essential points for removal or disassembly.
A: Indicates that there are essential points for installation or reassembly.
Symbols for Lubrication, Sealants and Adhesives
Information concerning the locations for lubrica-
tion and for application of sealants and adhe-
sives is provided, by using symbols, in the dia-
gram of component parts or on the page follow-
ing the component parts page, and explained.: Grease
(multipurpose grease unless there is a
brand or type specified)
: Sealant or adhesive
: Brake fluid or automatic transmission fluid
: Engine oil, gear oil or air conditioner com-
pressor oil
: Adhesive tape or butyl rubber tape
Component Diagram
A diagram of the component parts is
provided near the front of each section
in order to give a reader a better under-
standing of the installed condition of
component parts.

GENERAL – Special Handling Instruments for Towing00-20
SPECIAL HANDLING INSTRUMENTS FOR TOWING
Towing methodsRemarks
If a tow truck is used
Lifting method for 4 wheels – GoodFor 4WD models, the basic principle is that all
four wheels are to be raised before towing.
The shift lever should be set to 1st gear and
the parking brake should be applied.
Front wheels lifted – No goodThe vehicle must not be towed by placing only
its front wheels or only the rear wheels on a
rolling dolly, because to do so will result in
deterioration of the viscous coupling and result
in the viscous coupling causing the vehicle to
jump forward suddenly.
Front wheels lifted – No goodIf only the front wheels or only the rear wheels
are lifted for towing, the bumper will be damaged.
In addition, lifting of the rear wheels causes
the oil to flow forward, and may result in heat
damage to the rear bushing of the transfer, and
so should never be done.
Rear wheels lifted – No good
Towing by rope or cable – GoodThe front and rear wheels must rotate normally.
Both running and driving systems must function
normally.
The shift lever must be set to the neutral position
and the ignition key must be set to “ACC”.

GENERAL – Brake Test00-21
BRAKE TEST
In order to stabilize the viscous coupling’s dragging force,
the brake test should always be conducted after the
speedometer test.
FRONT WHEEL MEASUREMENTS
1. Place the front wheels on the brake tester.
2. Perform the brake test.
Caution
The rear wheels should remain on the ground.
3. If the brake dragging force exceeds the specified value,
jack up the vehicle and manually rotate each wheel to
check the rotation condition of each wheel.
NOTE
If the brake dragging force exceeds the specified value,
the cause may be the effect of the viscous coupling’s
dragging force, so jack up the front wheels and check
the rotation condition of the wheels in this state for no
effect by the viscous coupling’s dragging force.
REAR WHEEL MEASUREMENTS
After placing the rear wheels on the brake tester, follow the
same procedures as for the front wheel measurements.
