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.

HINT:
1. When doing this be careful of the other wheel which will ro-
tate at the same time.
2. Completely the measurement quickly, within a short time.

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

(special) tools and those which are considered to be
reasonable for the owner to perform.
Items and procedures for general maintenance are as
follows:

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.
