■When the center differential lock/unlock switch can be operated
The “ENGINE START STOP” switch is in IGNITION ON mode.
■The center differential lock indicator light
●The indicator light blinks while lockin g/unlocking the center differential.
●If the center differential lock indicato r light 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
●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 light will come on.)
●If the operation is not completed, the center differential lock indicator blinks. If
the indicator light 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 diff erential is locked. If you do turn sud-
denly, the difference in turning speeds between the front and rear wheels may
have a similar effect to braking, thus making driving difficult.

■Operating tips
The system will operate when the shift lever is in a position other than P, however to
make effective use of the system it is recommended that the shift lever be shifted to
2 or 1 range of S mode.
■If the four-wheel drive control switch is in H4
The system does not operate.
■When the downhill assist control system is operated continuously
This may cause the brake actuator to overheat. In this case, the downhill assist con-
trol system will stop operating, a buzzer will sound and the DAC indicator will start
flashing, and the TRAC OFF will be shown on the multi-information display. Refrain
from using the system until the DAC indicator stays on and the message goes off.
(The vehicle can be driven normally during this time.)

●A sound may be heard from the engi ne compartment when the engine is
started or just after the vehicle begins to move. This sound does not indicate that
a malfunction has occurred in DAC.
●Either of the following conditions may occur when the DAC is operating. None
of these are indicators that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
