■
When the four-wheel drive control switch can be operated
●
The engine switch is in IGNITION ON mode.
●
The shift lever is in the N position.
●
The vehicle is stopped completely.
■
The low speed four-wheel drive indicator
●
The indicator blinks while switching between H4 and L4.
●
If the low speed four-wheel drive indicator continues to blink when you operate the
four-wheel drive control switch to the H4 or L4 position, stop the vehicle completely,
shift the shift lever securely into N and then 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 drive shafts 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 shift lever is in P. You or someone else
could be seriously injured. You must complete the shifting of the transfer mode and
confirm that the indicator has turned off (H4) or turned on (L4).
●
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 indicator continue to blink even if doing so, have the vehicle inspected by your
Lexus dealer as soon as possible. There may be a trouble in the four-wheel drive system.
■
When the transfer mode is switched to L4
VSC is automatically turned off. (The VSC OFF indicator will come on.)
■
When the center differential lock/unlock switch can be operated
The engine switch is in IGNITION ON mode.
■
The center differential lock indicator
●
The indicator blinks while locking/unlocking the center differential.
●
If the center differential lock indicator blinks and the buzzer sounds when the center
differential is locked, stop the slipping or spinning and push the switch again.
If the indicator continue to blink even if doing so, have the vehicle inspected by your
Lexus dealer as soon as possible. There may be a trouble in the four-wheel drive system.
■
Locking/unlocking the center differential
●
If the operation is not completed, the center differential lock indicator blinks. If the indi-
cator does not turn off when unlocking the center differential, drive straight ahead
while accelerating or decelerating, or drive in reverse.
●
Avoid turning suddenly while the center differential is locked. If you do turn suddenly,
the difference in turning speeds between the front and rear wheels may have a similar
effect to braking, thus making driving difficult.
