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).

DANGER, WARNING, AND CAUTION

DANGER, WARNING, and CAUTION call special
attention to a necessary action or to an action that
must be avoided. The differences among DANGER,
WARNING, and CAUTION are as follows:

• If a DANGER is not followed, the result is severe

bodily harm or even death.

• If a WARNING is not followed, the result could be

bodily injury.

• If a CAUTION is not followed, the result could be

damage to the vehicle, vehicle components or
service equipment.

INDICATION OF TIGHTENING TORQUE

Tightening torques (units: N

⋅m) are set to take into

account the central value and the allowable
tolerance. The central value is the target value, and
the allowable tolerance provides the checking range
for tightening torques. If bolts and nuts are not
provided with tightening torques, refer to

P.00-30

.
