■Sensor detection information
● Certain vehicle conditions and the surrounding environment may affect
the ability of the sensor to correctly detect obstacles. Particular instances
where this may occur are listed below.
• There is dirt, snow or ice on the sensor. (Wiping the sensor will resolve
this problem.)
• The sensor is frozen. (Thawing the sensor will resolve this problem.)
• The sensor is covered in any way.
• In harsh sunlight or intense cold weather.
• When driving on bumpy, sloped or gravel roads, or over grass.
• If there is something producing ultrasonic waves nearby, such as another vehicle’s horn, motorcycle engine noise, air braking sound
from heavy-duty vehicles, or another vehicle using the park assist sys-
tem.
• In heavy rain, or if water is splashed on the sensors.
• The vehicle is leaning considerably to one side.
• If a commercial fender pole or radio antenna is installed.
• If moving towards a high curb or a curb corner.
• If towing eyelet is installed on your vehicle.
• The bumper or sensor receives a strong impact.
• A non-genuine Toyota suspension (lowered suspension etc.) is installed.
In addition to the examples above, there are instances in which, because of
their shapes, signs and other objects may be judged by the sensor to be
closer than they are.
● The shape of the obstacle may prevent the sensor from detecting it. Pay
particular attention to the following obstacles.
• Thin objects such as wire, fencing or rope.
• Objects that absorb sound waves, such as cotton or snow.
• Objects with sharp corners.
• Low objects.
• Objects where the upper section projects out over the lower section.

■The four-wheel drive control switch can be operated when
● The “ENGINE START STOP” switch is in IGNITION ON mode.
● The shift lever is in the “N” position.
● The vehicle is stopped completely.
■ The low speed four-wheel drive indicator light
The indicator light blinks while shifting between “H4” and “L4”.
■ 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 TRAC, 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/unlo ck button can be operated when
● The “ENGINE START STOP” switch is in IGNITION ON mode.
● The vehicle speed is less than 60 mph (100 km/h).
■ 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 in dicator 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.)
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 press 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 your Toyota dealer immediately.

When the system is turned off
If the system is turned off when Crawl Control is operating, the slip
indicator turns off, and the Crawl Control indicator flashes until the
system has turned off completely. When turning off Crawl Control
while traveling, stop the vehicle before the Crawl Control indicator
turns off, or drive extremely carefully.
■ The Crawl Control can be operated when
● The engine is running.
● The shift lever is in any gear other than “P” or “N”.
● The four-wheel drive control switch is in “L4”.
● The driver’s door is closed.
■ Automatic system cancelation
In either of the following situations, a buzzer sounds for approximately 3 sec-
onds. The Crawl Control indicator goes off after the system has automati-
cally turned off:
● When the shift lever is moved to “P”.
● When the four-wheel drive control switch is in “H4”.
In either of the following situations, a buzzer sounds for approximately 3 sec-
onds, the Crawl Control indicator blinks, and the control will decrease gradu-
ally. The Crawl Control indicator goes off after the system has automatically
turned off:
● When the shift lever is moved to “N”.
● If the driver’s door is opened.

NOTICE
■
To prevent the water damage
Take all necessary safety measures to ensure that water damage to the
engine or other components does not occur.
● Water entering the engine air intake will cause severe engine damage.
● Water entering the automatic transmission will cause deterioration in shift
quality, locking up of your transmission accompanied by vibration, and ulti-
mately damage.
● Water can wash the grease from wheel bearings, causing rusting and pre-
mature failure, and may also enter the differentials, transmission and
transfer case, reducing the gear oil’s lubricating qualities.
■ When you drive through water
If driving through water, such as when crossing shallow streams, first check
the depth of the water and the bottom of the river bed for firmness. Drive
slowly and avoid deep water.
■ Inspection after off-road driving
● Sand and mud that has accumulat ed in brake drums and around brake
discs may affect braking efficiency and may damage brake system compo-
nents.
● Always perform a maintenance inspection after each day of off-road driv-
ing that has taken you through rough terrain, sand, mud, or water. For
scheduled maintenance information, refer to the “Scheduled Maintenance
Guide” or “Owner’s Manual Supplement”.

Winter driving tips
Carry out the necessary preparations and inspections before driving
the vehicle in winter. Always drive the vehicle in a manner appropri-
ate to the prevailing weather conditions.
■ Pre-winter preparations
●Use fluids that are appropriate to the prevailing outside tem-
peratures.
• Engine oil
• Engine coolant
• Washer fluid
● Have a service technician inspect the level and specific grav-
ity of battery electrolyte.
● Have the vehicle fitted with four snow tires or purchase a set
of tire chains for the rear tires.
Ensure that all tires are the same size and brand, and that chains
match the size of the tires.

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 v ehicles. Passing requires consider-
able distance. After passing a vehi cle, 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 “4”, in “S” mode.
● Due to the added load of the trailer, your vehicle’s engine may
overheat on hot days (at temperatur es over 85°F [30°C] when driv-
ing up a long or steep grade. If the engine coolant temperature
gauge indicates overheating, immediately turn off the air condition-
ing (if in use), pull your vehicle off the road and stop in a safe spot.
