ON±VEHICLE WHEEL BALANCING
NOTICE:
1. When doing on±vehicle wheel balancing on a fulltime 4WD
vehicle, to prevent the wheels from rotating at different
speeds or in different directions from each other (which
could lead to damage to the center differential or trans-
axle gears), always be sure to observe the following pre-
cautions:
(1) A11 four wheels should be jacked up, completely clear
of the ground.
(2) The wheels should be driven by both the engine and
the wheel balancer.
(3) The center differential control switch should be in the
OFF condition.
(4) The mode select lever on the transaxle should be in
the LOCK position.
(5) The parking brake lever should be fully released.
(6) None of the brakes should be allowed to drag.
2. Avoid sudden acceleration, deceleration and braking.
3. Carry out the wheel balancing with the transmission in D
range.
1. SET CENTER DIFFERENTIAL CONTROL SWITCH TO
OFF
(1) Check that the center differential control indicator light
goes off.
(2) Further check that hydraulic multiplate clutch control of
the center differential is in OFF condition.

GENERAL MAINTENANCE
These are the maintenance and inspection items
which are considered to be the owner's responsibility,
They can be performed by the owner or he
can have then done at a service shop. These items
include those which should be checked on a daily ba-
sis, those which, in most cases, do not require
(special) tools and those which are considered to be
reasonable for the owner to perform.
Items and procedures for general maintenance are as
follows:
OUTSIDE VEHICLE
1. TIRES
(a) Check the pressure with a gauge. Adjust
if necessary.
(b) Check for cuts, damage or excessive wear.
2. WHEEL NUTS
When checking the tires, check the nuts for looseness
or for missing nuts. If necessary,
tighten them.
3. TIRE ROTATION
It is recommended that tires be rotated every
7,500 miles (12,000 km).
4. WINDSHIELD WIPER BLADES
Check for wear or cracks whenever they do not wipe
clean. Replace if necessary.
5. FLUID LEAKS
(a) Check underneath for leaking fuel, oil, water or
other fluid.
(b) If you smell gasoline fumes or notice any leak,
have the cause found and corrected.
6. DOORS AND ENGINE HOOD
(a) Check that all doors including the trunk lid and
back door operate smoothly, and that all
latches lock securely.
(b) Check that the engine hood secondary latch se-
cures the hood from opening when the prima-
ry latch is released.
INSIDE VEHICLE
7. LIGHTS
(a) Check that the headlights, stop lights, taillights,
turn signal lights, and other
lights are all working.
(b) Check the headlight aiming.8. WARNING LIGHTS AND BUZZERS
Check that all warning lights and buzzers func-
tion properly.
9. HORN
Check that it is working.
10. WINDSHIELD GLASS
Check for scratches, pits or abrasions.
11. WINDSHIELD WIPER AND WASHER
(a) Check operation of the wipers and washer.
(b) Check that the wipers do not streak.
12. WINDSHIELD DEFROSTER
Check that air comes out from the defroster out-
let when operating the heater or air conditioner
at defroster mode.
13. REAR VIEW MIRROR
Check that it is mounted securely.
14. SUN VISORS
Check that they move freely and are mounted
securely.
15. STEERING WHEEL
Check that it has the specified freeplay. Be alert
for changes in steering condition, such as hard
steering, excessive freeplay or strange noise.
16. SEATS
(a) Check that all front seat controls such as
seat adjusters, seatback recliner, etc.
operate smoothly.
(b) Check that a11 latches lock securely in
any position.
(c) Check that the locks hold securely in any
latched position.
(d) Check that the head restraints move up
and down smoothly and that the locks
hold securely in any latched position.
(e) For folding±down rear seat backs, check
that the latches lock securely.

Single Unit Inspection
DIFFERENTIAL LOCK SWITCH
1. INSPECT CONTINUITY OF DIFFERENTIAL LOCK
SWITCH
(a) Disconnect the differential lock switch connector.
(b) Check continuity between terminals 1 to 4.
Switch ON: Continuity
Switch OFF: No continuity
4WD CONTROL SOLENOID
1. INSPECT OPERATION OF 4WD CONTROL SOLENOID
Check air flow of each port when the battery voltage is
applied and is not applied to terminals No.1, No.2 of
the solenoid.
Function Inspection
DIFFERENTIAL LOCK CONTROL
INSPECT DIFFERENTIAL LOCK OPERATION
Start the engine. Check that the differential lock indica-
tor light comes on when the differential lock control
switch is turned to ON. Check that the light goes off
when the switch is turned to OFF.
HINT: After checking the system, turn the control switch
to OFF and check that the differential lock function is
released.
Reference: If the indicator light does not come on and
go out when the control switch is operated, move the
vehicle
slightly forward. when the system is operated it should
be normal.
TRANSFER VACUUM ACTUATOR
1. INSPECT ACTUATOR HOSE CONNECTION
Check that the actuator hoses are connected to the
solenoids and actuator tightly and properly.
