■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 15 mph (25 km/h).
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 6 mph (10km/h).
●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 “TRAC OFF” on the multi-
information display goes off. (In the meantime, normal driving is possi-
ble.)
●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. 606, 617)
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.

■Multi-terrain Select control starting conditions
When all of the following conditions are satisfied, the Multi-ter-
rain Select indicator will come on, the mode select screen will be
displayed on the multi-information display, and Multi-terrain
Select control will begin.
●The four-wheel drive control switch is in “L4”.
●Both Active TRAC and VSC are not off.
●Crawl Control is off.

■Automatic system cancelation
In the following situations, the Multi-terrain Select indicator will go off, and
Multi-terrain Select will be canceled automatically.
●When the four-wheel drive control switch is in “H4”.
●When Active TRAC and VSC are off.
●When Crawl Control is on.
■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
Switching the transfer and differential
For the operation of the following functions, refer to the following pages.
●Four-wheel drive system (P. 240)
●Center differential lock (P. 240)
■When the brake system operates continuously
The brake system may overheat. In this case, a buzzer will sound, either the
“TRAC OFF” will be displayed on the multi-information display, and Multi-ter-
rain Select will be temporarily inoperable. In this event, stop the vehicle
immediately in a safe place, and allow the brake system to cool down suffi-
ciently. (There is no problem with continuing normal driving.)
After a short time, the message on the multi-information display will go off,
and you will be able to use Multi-terrain Select.
■When there is a malfunction in the system
The slip indicator light will come on. Have the vehicle inspected by your
Toyota dealer immediately.
