Advice for driving on slippery roads
If you shift the four-wheel drive control switch to “L4” and the shift lever to
the “2” range of “S” while driving in steep off-road areas, the output of the
brake can be controlled effectively by the Active TRC, which assists the
driver to control the driving power of 4 wheels.
Use the “1” range of “S” of the shift lever for maximum power and traction
when your wheels get stuck or when driving down a steep incline.
The center differential lock indicator light
The indicator light blinks while locking/unlocking the center differential.
The center differential lock/unlock button can be operated when
The “ENGINE START STOP” switch is in IGNITION ON mode.
The vehicle speed is less than 100 km/h (60 mph).
Locking/unlocking the center differential
When the center differential is 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 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.
If the center differential lock/unlock is not completed within 5 seconds
while the cruise control system is on, cancel the cruise control system.

If the low speed four-wheel drive indicator light or the center differen-
tial lock 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 trans-
fer mode disengages both the front and rear driveshafts from the power-
train 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
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 sys-
tem. 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 any authorized Toyota dealer or repairer, or another duly qualified and
equipped professional immediately.

CAUTION
While driving
Never move the four-wheel drive control switch if the wheels have lost trac-
tion. Doing so may cause an accident resulting in death or serious injury.
When the vehicle is parked
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 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. (P. 259)
NOTICE
To prevent damage to the center differential
For normal driving on dry and hard surface roads, unlock the center differ-
ential.
Unlock the center differential after the wheels are out of the ditch or off the
slippery or bumpy surface.
Do not push the center differential lock/unlock button when the vehicle is
turning or when its wheels are spinning freely off the ground.

When it is difficult to generate traction
MUD & SAND mode provides the largest amount of tire slippage, followed
by LOOSE ROCK, MOGUL, ROCK & DIRT and ROCK mode.
Drivability can be improved by selecting a mode which provides a smaller
amount of tire slippage than the current mode when the amount of tire slip-
page is large, or conversely selecting a mode which provides a larger
amount of tire slippage than the current mode when the amount of tire slip-
page is small.
When the vehicle is stuck
