The center differential lock indicator light
The indicator light blinks while locking/unlocking the center differential.■
The center differential lock/unlock switch can be operated when ●
The engine switch is in IGNITION ON mode. ●
The vehicle speed is less than 62 mph (100 km/h). ■
Locking/unlocking the center differential●
When the four-wheel drive control switch is in L4 with the center differential locked,
VSC is automatically turned off. (The center differential lock and VSC OFF indicator
lights come on.) ●
If the operation is not completed, the center di fferential lock indicato r blinks. If the indi-
cator light does not turn off when unlocking the center diff erential, drive straight ahead
while accelerating or decelera ting, or drive in reverse.●
If the center differential lock/unlock is no t completed within 5 se conds while the cruise
control system is on, cancel the cruise control system.■
If the low speed four-wheel driv e indicator light or the center differential lock indicator
light blinks ●
If the low speed four-wheel drive indicator lig ht continues to blink when using the four-
wheel drive control switch, st op the vehicle completely, move the shift lever to N and
operate the switch again. ●
If the shift lever is moved before the low speed four-wheel drive indicator turns on/off,
the transfer mode may not be shifted completely. The transfer mode disengages both
the front and rear driveshafts from the po wertrain and allows the vehicle to move
regardless of the shift position. (At this time , the indicator blinks and the buzzer sounds.)
Therefore, the vehicle is free to roll even if the automatic transmission is in P. You or
someone else could be seriously injured. You must complete the shifting of the transfer
mode.
To complete the shifting, stop the vehicle co mpletely, return the shift lever to N, and
confirm that the shift was completed (the indicator turns on/off). ●
If the engine coolant temperature is too low, the four-wheel drive control system may
not be able to shift. When the engine is warmer operate the switch again.
If the low speed four-wheel drive indicator light or the center differential lock indicator
light continues to blink even after attempting the above, there may be a malfunction in
the engine, the brake system or the four-wheel drive system. In this case, you may not be
able to shift between H4 and L4, and the cent er differential lock may not be operable.
Have the vehicle inspected by your Lexus dealer immediately.
