■
indicator light blinks
If the low speed four-wheel drive indicator light continues to blink when using
●
the four-wheel drive control switch, stop 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 dis-
engages 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).
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 indi-
cator light continues to blink even after attempting the above, there may be a mal-
function 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 center differential lock
may not be operable. Have the vehicle inspected by your Lexus dealer immediately.
