HOW TO USE THIS MANUAL
SCOPE OF MAINTENANCE, REPAIR
AND SERVICING EXPLANATIONS
This manual provides explanations, etc. concerning
procedures for the inspection, maintenance, repair
and servicing of the subject model. Note, however,
that for engine and transmission-related component
parts, this manual covers only on-vehicle
inspections, adjustments, and the removal and
installation procedures for major components.
For detailed information concerning the inspection,
checking, adjustment, disassembly and reassembly
of the engine, transmission and major components
after they have been removed from the vehicle,
please refer to separate manuals covering the
engine and the transmission.
ON-VEHICLE SERVICE
“On-vehicle Service” is procedures for performing
inspections and adjustments of particularly
important locations with regard to the construction
and for maintenance and servicing, but other
inspection (for looseness, play, cracking, damage,
etc.) must also be performed.
INSPECTION
Under this title are presented inspection and
checking procedures to be performed by using
special tools and measuring instruments and by
feeling, but, for actual maintenance and servicing
procedures, visual inspections should always be
performed as well.
DEFINITION OF TERMS
STANDARD VALUE
Indicates the value used as the standard for judging
the quality of a part or assembly on inspection
or the value to which the part or assembly is
corrected and adjusted. It is given by tolerance.
LIMIT
Shows the standard for judging the quality of a
part or assembly on inspection and means the
maximum or minimum value within which the part
or assembly must be kept functionally or in strength.
It is a value established outside the range of
standard value.
REFERENCE VALUE
Indicates the adjustment value prior to starting the
work (presented in order to facilitate assembly and
adjustment procedures, and so they can be
completed in a shorter time).
CAUTION
Indicates the presentation of information particularly
vital to the worker during the performance of
maintenance and servicing procedures in order to
avoid the possibility of injury to the worker, or
damage to component parts, or a reduction of
component or vehicle function or performance, etc.
INDICATION OF TIGHTENING TORQUE
The tightening torque shown in this manual is a
basic value with a tolerance of ±10% except the
following cases when the upper and lower limits
of tightening torque are given.
(1) The tolerance of the basic value is within ±10%.
(2) Special bolts or the like are in use.
(3) Special tightening methods are used.

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.
