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.

L/C200_EE (OM60G38E)
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.

Crawl Control (with Tur n Assist function)
Allows travel on extremely rough off-road surfaces at a fixed low
speed without pressing the accelerator or brake pedal. Minimizes
loss of traction or vehicle slip when driving on slippery road sur-
faces, allowing for stable driving.

Speed modes
The following table shows
some typical terrains and the
recommended speed modes.
Turn Assist function
This function assists cornering performance in accordance with
steering operation when driving through a tight corner. It main-
tains vehicle speed while driving and reduces the number of
turns needed to navigate a corner that requires turning the
wheel in the opposite direction.
Press the Turn Assist switch

ing.

When the system is turned off
Crawl Control
Press the ON/OFF switch while Crawl Control is operating. If the
switch is turned off, the slip indicator and the Turn Assist indicator
will go off (if the Turn Assist function is in use), the Crawl Control
indicator will flash until the system has turned off completely, and a
message stating that Crawl Control has been turned off will be dis-
played on the multi-information display for several seconds.
When turning off Crawl Control while driving, stop the vehicle
before the Crawl Control indicator turns off, or drive extremely
carefully.
Turn Assist function
Press the Turn Assist switch while the Turn Assist function is oper-
ating. When the switch is pressed, the Turn Assist indicator will go

Function limitations
Crawl Control
In the following situations, brake control can be used to drive downhill at
a constant speed. However, engine control is not available when driving
uphill at a constant speed.
• When switched to second start mode.
In the following situation, engine control and brake control will stop tem-
porarily. In this event, the Crawl Control indicator will flash.
• When the vehicle speed exceeds approximately 25 km/h (15 mph).
Turn Assist function
In the following situations, the Turn Assist function will stop temporarily. In
this event, the Turn Assist indicator will flash.
When the vehicle speed exceeds approximately 10km/h (6 mph).
When the shift lever is moved to “R”.
When the Crawl Control system is operated continuously
If Crawl Control is used continuously for a long time, the buzzer will
sound, a malfunction notification will be displayed on the multi-informa-
tion display, the Crawl Control indicator will go off, and Crawl Control will
be temporarily inoperable as a result of the brake system overheating. In
this event, stop the vehicle immediately in a safe place, and allow the
brake system to cool down sufficiently until the “TRC OFF” on the multi-
information display go off. (In the meantime, normal driving is possible.)
If Crawl Control is used continuously for a long time, the buzzer will
sound, the system will be temporarily canceled, and a malfunction notifi-
cation will be displayed on the multi-information display as a result of the
automatic transmission system overheating. Stop the vehicle in a safe
place until the display goes off.

Sounds and vibrations caused by the Crawl Control system
A sound may be heard from the engine compartment when the engine is
started or just after the vehicle begins to move. This sound does not indi-
cate that a malfunction has occurred in Crawl Control system.
Either of the following conditions may occur when the Crawl Control sys-
tem is operating. None of these are indicators that a malfunction has
occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
When there is a malfunction in the system
Warning lights and/or warning messages will turn on. (P. 573, 579)
CAUTION
When using Crawl Control and Turn Assist function
Do not rely solely on the Crawl Control and Turn Assist function. This func-
tion does not extend the vehicle’s performance limitations. Always thor-
oughly check the road conditions, and drive safely.
These conditions may cause the system not to operate properly
When driving on the following surfaces, the system may not be able to main-
tain a fixed low speed, which may result in an accident:
Extremely steep inclines.
Extremely uneven surfaces.
Snow-covered roads, or other slippery surfaces.
NOTICE
When using Turn Assist function
The Turn Assist function is a function to assist turning performance when
driving off road. The function may be less effective on paved road surfaces.
