EXPLANATION OF MANUAL CONTENTSIndicates 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.
Maintenance and Servicing Procedures
(1) A diagram of the component parts is provided near the front of each section in
order to give the reader a better under-
standing of the installed condition of
component parts.
(2) The numbers provided within the diagram indicate the sequence for maintenance
and servicing procedures; the symbol
mindicates a non-reusable part; the tighten-
ing torque is provided where applicable. l Removal steps:
The part designation number corres-
ponds to the number in the illustration
to indicate removal steps.
l Disassembly steps: The part designation number corres-
ponds to the number in the illustration
to indicate disassembly steps.
l Installation steps: Specified in case installation is impossi-
ble in reverse order of removal steps.
Omitted if installation is possible in
reverse order of removal steps.
8 Reassembly steps: Specified in case reassembly is im-
possible in reverse order of disassem-
bly steps.
Omitted if reassembly is possible in reverse order of disassembly steps.
Classificationsof Major Maintenance/
Service Points
When there are major points relative to mainte-
nance and servicing procedures (such as essential
maintenance and service points, maintenance and
service standard values, information regarding the
use of special tools, etc.), these are arranged
together as major maintenance and service points
and explained in detail.

FOR AWD MODELS

Towing methods
If a tow truck is used Lifting method for 4 wheels-Good Remarks
l For AWD models, the basic principle is that
all four wheels are to be raised before
towing.
l The shift lever should be set to 1
st gear and
the parking brake should be applied. >
l The selector lever should be set to “P” position and the parking brake should be
applied.

OOA0032
Front wheels lifted-No good l The vehicle must not be towed by placing
only its front wheels or only the rear wheels
on a rolling dolly, because to do so willresult in deterioration of the viscous
coupling and result in the viscous coupling
causing the vehicle to jump forward
suddenly.
OOA0034
Front wheels lifted-No good l
If 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
