IN−16 − INTRODUCTION FOR ALL OF VEHICLES Center Differential Lock Indicator Light 2. WHEN SERVICING FULL−TIME 4WD VEHICLES The Full−time 4WD LEXUS LX470 is equipped with the me- chanical lock type center differential system. 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 (brak- ing 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 will not only be unsuccessful, but may be dangerous as well.
Therefore, before beginning any such servicing or test, be sure to check the following items: Center differential mode position (FREE or LOCK) Whether wheels should be touching ground or jacked up Transmission gear position (N position) Transfer gear position (H or L position) Maximum testing vehicle speed Maximum testing time CAUTION:
Never accelerate or decelerate the vehicle suddenly Observe the other cautions given for each individual test (a) 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 performed. Select the position of the center differential by pushing the center differential lock switch with the transfer select lever to ”H” position. After selecting the position, confirm the op- eration of indicator light. HINT:
Move the vehicle forward or backward slightly if the indi- cator light does not operate correctly when the center dif- ferential lock switch is turned ON or OFF. When the transfer select lever is put in ”L” position, the center differential is put in LOCK condition regardless of the position of the center differential lock switch.
