CAUTIONS WHEN MODE SELECT LEVER IS IN ºFREEº
OR ºLOCKº MODE
FREE MODE
(1) Do not drive off suddenly or apply the accelerator or
brakes suddenly. Always start slowly and decelerate
gradually.
(2) If either the front or the rear wheels are placed on the
tester rollers in the FREE mode, be careful not to exceed
the following limits:
Maximum speed:
Speed indicated on speedometer
19 mph(30 km/h) or
Wheel speed (Tester speed)
38 mph160 km/h)
Maximum test time: 60 sec.
Note that the actual wheel speed (tester speedy is twice the
speed indicated by the speedometer due
to center differential operation.
LOCK MODE
(1) Do not drive off suddenly or apply the accelerator or
brakes suddenly. Always start slowly and decelerate
gradually.
(2) Be sure to conduct the test with the rear propeller
shaft removed.6. AFTER FINISHING TEST, RETURN MODE SELECT
LEVER TO ºFREE (NORMAL)º MODE POSITION AND

7. SET CENTER DIFFERENTIAL CONTROL SWITCH TO
AUTO 5. CONFIRM MODE
FREE (Normal) Mode:
A lifted wheel can be rotated even if only one wheel is lifted
up, as long as transmission is in N range.
LOCK Mode:
A lifted wheel cannot be rotated if only one wheel is
lifted up, even if transmission is in N range.

BRAKING FORCE TEST
HINT: According to the vehicle speed during the test, select
one of the two test methods described below, either A or B.
Method A : Conduct the test with the center differen±
(Low Speed Test) tial control switch oft and the select lever
on the transaxle in the FREE (Normal)
mode.

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.

4. JACK UP VEHICLE So THAT ALL FOUR WHEELS CAN
ROTATE
The wheels will be rotating fast, so make sure the vehicle is
firmly supported on stands.
7. PLACE WHEEL TO BE BALANCED ON WHEEL
BALANCER
Follow the procedure specified by the wheel balancer
manufacturer.
8. START ENGINE
9. PUT TRANSMISSION IN ºDº RANGE, THEN
GRADUALLY INCREASE SPEED TO TEST SPEED 6. MAKE SURE THAT BRAKES ARE NOT DRAGGING
