indicator flashes to indicate that
the AUTO LSD system has con-
trolled the spinning of the rear
wheels.

■If the engine is turned off and restarted
The AUTO LSD system and the indicators are automatically turned off.
■ If the brake system overheats
The system will cease operation and a buzzer will sound to alert the driver.
At this time, the “AUTO LSD” indicato r will flash and the “TRAC OFF” indica-
tor will come on. Stop the vehicle in a safe place. (There is no problem with
continuing normal driving.)
The system will be automatically restored after a short time.
CAUTION
■ To avoid an accident
● Do not use the AUTO LSD system in conditions other when wheel spin-
ning occurs in a ditch or rough surfaces.
A much greater steering effort and more careful cornering control will be
required.
● Do not drive with the AUTO LSD system continuously turned on.

indicate that the downhill assist
control system is operating, and
the stop lights and high mounted

■Operating tips
The system will operate when the shift lever is in any position other than P.
However, to make effective use of the system it is recommended that the
shift lever be shifted to the “2” or “1” range of S.
■ If the downhill assist control system indicator flashes
● In the following situations, the indicator flashes and the system will not
operate:
• The transfer mode is not in L4 (part-time 4WD models) or L4L (full-time
4WD models).
• The rear differential is locked.
• The brake system overheats. The system will situations operation and a buzzer will sound to alert the
driver. At this time, the “TRAC OFF (TRC OFF)” indicator will come on.
Stop the vehicle in a safe place. Refrain from using the system until the
indicator stops flashing and stays on. (There is no problem with con-
tinuing normal driving.)
● In the following situations, the indicato r flashes to alert the driver, but the
system will still operate:
• The shift lever is in N. (Engine braking will not occur.)
• The “DAC” switch is turned off while the system is operating. The system will gradually ceases operation. The indicator will flash dur-
ing operation, and then go off when the system is fully off.

■Crawl Control is temp orarily canceled when
Vehicle speed exceeds 15 mph (25 km/h). The Crawl Control indicator
flashes until the vehicle speed is reduced.
■ Automatic system cancelation
In the following situations, the system will cease operation and a buzzer will
sound to alert the driver. The Crawl Control indicator will flash until the sys-
tem is turned off completely.
● When the shift lever is shifted to P or N
● When the front-wheel drive control lever is shifted to H4
● When the driver’s door is opened
● When the system is malfunctioning
● When the brake system overheats
Stop the vehicle in a safe place. (There is no problem with continuing
normal driving.)
● When the automatic transmission system overheats
Stop the vehicle in a safe place until the automatic transmission fluid tem-
perature warning light 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 indicates 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.

■Hill-start assist control operation conditions
● The shift lever is in D or S.
● The brake pedal is not depressed.
● The rear differential is unlocked (if equipped).
■ If the brake system overheats
The hill-start assist control will cease operation and a buzzer will sound to
alert the driver. At this time, the “TRAC OFF (TRC OFF)” indicator will come
on. Stop the vehicle in a safe place. (There is no problem with continuing
with normal driving.)
The system will be automatically restored after a short time.
■ Sounds and vibrations caused by the ABS, Multi Terrain ABS (if
equipped), brake assist, VSC, TRAC (TRC) and hill-start assist control
(if equipped) systems
● 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 any of these systems.
● Any of the following conditions may occur when the above systems are
operating. None of these indicates 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.
• The brake pedal may pulsate slightly after the ABS or Multi Terrain
ABS is activated.
• The brake pedal may move down slightly after the ABS or Multi Terrain ABS is activated.
■ Reactivation of the TRAC (TRC)/VSC systems after turning off the
engine
Turning off the engine after turning off the TRAC (TRC)/VSC systems will
automatically reactivate them.
■ Reactivation of the VSC system linked to vehicle speed (2WD models)
When the TRAC system is turned off and the AUTO LSD system is turned
on, the VSC system will turn on when vehicle speed increases. However,
when the TRAC and VSC systems are turned off, the systems will not turn
on even when vehicle speed increases.

●
Note that when making a turn, th e trailer wheels will be closer than
the vehicle wheels to the inside of the turn. Compensate by making
a larger than normal turning radius.
● Crosswinds and rough roads will adversely affect handling of your
vehicle and trailer, causing sway . Periodically check the rear to
prepare for being passed by large trucks or buses, which may
cause your vehicle and trailer to sway. If swaying occurs, firmly grip
the steering wheel, reduce speed immediately but gradually, and
steer straight ahead. Never increase speed. If you make no
extreme correction with the stee ring or brakes, your vehicle and
trailer will stabilize.
● Take care when passing other vehicles. Passing requires consider-
able distance. After passing a vehicle, do not forget the length of
your trailer, and be sure you hav e plenty of room before changing
lanes.
● In order to maintain engine braking efficiency when driving on a
long steep downgrade, do not use overdrive. Transmission shift
range position must be in 3 (standard type), or “4”, in the S mode
(multi-mode type).
● Due to the added load of the trailer, your vehicle’s engine may
overheat on hot days (at temperatures over 85°F [30°C]) when
driving up a long or steep grade. If the engine coolant temperature
gauge indicates overheating, immedi ately turn off the air condition-
ing (if in use), pull your vehicle off the road and stop in a safe spot.

CAUTION
■
Burns
● Use caution when seating the following persons in a seat with the seat
heater on to avoid the possibility of burns:
• Babies, small children, the elderly, the sick and the physically chal-
lenged
• Persons with sensitive skin
• Persons who are fatigued
• Persons who have taken alcohol or drugs that induce sleep (sleeping drugs, cold remedies, etc.)
● Do not cover the seat with anything when using the seat heater.
Using the seat heater with a blanket or cushion increases the temperature
of the seat and may lead to overheating.
● Do not use the seat heater more than necessary. Doing so may cause
minor burns or overheating.
NOTICE
■To prevent seat heater damage
Do not put heavy objects that have an uneven surface on the seat and do
not stick sharp objects (needles, nails, etc.) into the seat.
■ To prevent battery discharge
Turn the seat heaters off when the engine is not running.

If your vehicle overheats
If your engine overheats:Stop the vehicle in a safe place and turn off the air condi-
tioning system.
Check to see if steam is coming out from under the hood.
If you see steam:
Stop the engine. Carefully lift the hood after the steam sub-
sides and then restart the engine.
If you do not see steam:
Leave the engine running and carefully lift the hood.
Remove the engine compartment cover. (
P. 497)
Check to see if the cooling fan is operating.
If the fan is operating:
Wait until the temperature of the engine (shown on the
instrument panel) begins to fall and then stop the engine.
If the fan is not operating:
Stop the engine immediately and call your Toyota dealer.
After the engine has cooled
down sufficiently, check the
engine coolant level and
inspect the radiator core (radi-
ator) for any leaks.
