PRECAUTIONS WHEN SERVICING
FULL±TIME 4WD VEHICLES
The 1990 model year full±time 4WD Camry is equipped with two
types of transaxle ± either the manual transaxle or the automatic
transaxle. The center differential system of the manual transaxle
is the mechanical lock type. The center differential
system of the automatic transaxle is a hydraulic multiplate clutch
control type. When carrying out any kind of servicing 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 balanc-
ing, etc.), or when towing the vehicle, be sure to observe the pre-
cautions given below. If incorrect preparations or test procedures
are used, the test cannot be successfully carried out, and may
be dangerous as well. Therefore, before beginning any such ser-
vicing or test, be sure to check the following items:
(1) Center differential lock type
(2) Center differential mode position
(3) Whether wheels should be touching ground or jacked up
(4) Transmission gear position
(5) Maximum testing vehicle speed
(6) Maximum testing time
Also be sure to observe the following cautions:
(1) Never accelerate or decelerate the vehicle suddenly.
(2) Observe the other cautions given for each individual test.
1. MANUAL TRANSAXLE MODELS:
(Mechanical Lock Type Center
Differential)
BEFORE BEGINNING TEST
During tests with a brake tester or chassis dynamometer, 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 differential to the FREE position or to the LOCK
position depending on the type of test being perform.
(1) Select the position of the center differential by pushing the cen-
ter differential control switch.
(2) After selecting the position, confirm the operations of indicator
light and center differential as follows:
HINT: Move the vehicle backward or forward slightly if the indica-
tor light does not operate correctly when the center
differential control switch is turned ON or OFF.
CAUTIONS WHEN CENTER DIFFERENTIAL CONTROL
SWITCH IS TURNED ON
wOperate the switch only when the all four wheels are stopped or
when driving with the wheels in a straight line.
wNever operate the switch under the following conditions.
(1) When any tire is slipping.
(2) When any tire is spinning freely.
(3) When swerving or cornering.
