2-4. Using other driving systems n If the 4LO indicator, 4HI indicator or the center differential lock indicator blinks l If the 4LO indicator continues to blink when shifting between 4H and 4L, stop the vehicle completely, move the shift lever to N and operate the switch again. l If the shift lever is moved before the 4LO indicator turns on/off, the transfer mode may not be shifted completely. The transfer mode disengages both the front and rear driveshafts from the powertrain 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 completely, return the shift lever to N, and confirm that the shift was completed (The indicator turns on/off). l If the engine coolant temperature is too low, transfer mode may not be able to shift. When the engine is warmer, turn the switch again. If the 4LO indicator, 4HI indicator or the center differential lock indicator 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 2WD and 4H, 4H and 4L, and the center differential lock may not be operable. Have the vehicle inspected by your Toyota dealer immediately. n Shifting to 4L position The VSC OFF indicator will come on. If the center differential is locked, VSC is automatically turned off. 232
