VEHICLES
The full —time 4WD Land Cruiser Station Wagon is
equipped with the mechanical lock type center dif-
ferential system. When carrying out any kind of ser-
vicing or testing on a full —time 4WD in which the
front or rear wheels are made to rotate (braking test,
speedometer test, on —vehicle wheel balancing, etc.),
or when towing the vehicle, be sure to observe the
precautions given below. If incorrect preparations or
test procedures are used, the test cannot be suc-
cessfully carried out, and may be dangerous as well.
Therefore, before beginning any such servicing or
test, be sure to check the following items:
(1) Center differential lock type
(2) (w/o ABS)
Center differential mode position (FREE or LOCK)
(3) Whether wheels should be touching ground or
jacked up
(4) Transmission gear position
(5) Transfer gear position (H or L)
(6) Maximum testing vehicle speed
(7) Maximum testing time
Also be sure to observe the following cautions:
(1) Never accelerate or decelerate the vehicle sud-
denly.
(2) Observe the other cautions given for each indi-
vidual test.
Before Beginning Test
During tests with a brake tester or chassis dyna-
mometer, such as braking force tests or speedometer
tests, if only the front or rear wheels are to be rotated,
it is necessary to set the position of the center dif-
ferential to the FREE position or to the LOCK position
depending on the type of test being performed.
(1) (w/o ABS)
Select the position of the center differential by
pushing the center differential lock switch with
the transfer select lever to "H" position.
(2) After selecting the position, confirm the opera-
tion of indicator light.
