WARNING
■When using the rear view monitor system
The rear view monitor system is a supplemental device intended to assist
the driver when backing up. When backing up, be sure to check visually
behind and all around the vehicle before proceeding.
Observe the following precautions to avoid an accident that could result in
death or serious injuries.
● Never depend on the rear view monitor system entirely when backing up.
The image and the position of the guide lines displayed on the screen may
differ from the actual state.
Use caution, just as you would when backing up any vehicle.
● Be sure to back up slowly, depressing the brake pedal to control vehicle
speed.
● The instructions given are only guide lines.
When and how much to turn the steering wheel will vary according to traf-
fic conditions, road surface conditions, vehicle condition, etc. when park-
ing. It is necessary to be fully aware of this before using the rear view
monitor system.
● When parking, be sure to check that the parking space will accommodate
your vehicle before maneuvering into it.
● Do not use the rear view monitor system in the following cases:
• On icy or slick road surfaces, or in snow
• When using tire chains or the compact spare tire (if equipped)
• When the back door is not closed completely
• On roads that are not flat or straight, such as curves or slopes.
● In low temperatures, the screen may darken or the image may become
faint. The image could distort when the vehicle is moving, or you may
become unable to see the image on the screen. Be sure to check direct
visually and with the mirrors all around the vehicle before proceeding.
● If the tire sizes are changed, the position of the fixation guide lines dis-
played on the screen may change.
● The camera uses a special lens. The distances between objects and
pedestrians that appear in the image displayed on the screen will differ
from the actual distances. ( →P. 289)

All-wheel drive lock switch (AWD models)
Press the switch.
The torque of the engine is distrib-
uted to the rear wheels to the max-
imum extent possible in
accordance with driving conditions.
Pressing the switch again cancels
all-wheel drive lock mode and
returns the Dynamic Torque Con-
trol AWD system to normal mode.
(→P. 298)
■ All-wheel drive lock mode can be operated when
Vehicles without smart key system
The engine switch is in the “ON” position.
Vehicles with smart key system
The engine switch is in IGNITION ON mode.
■ All-wheel drive lock mode
●All-wheel drive lock mode is canceled when the brakes are applied to
ensure the ABS and VSC systems operate effectively.
● All-wheel drive lock mode is cancel ed when the vehicle speed exceeds 25
mph (40 km/h).
All-wheel drive lock mode can be used when a large amount of
drive power needs to be applied to all the wheels, such as when
the vehicle gets stuck in mud and you need to free it.

Driving assist systems
◆ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if the
brakes are applied while driving on a slippery road surface
◆Brake assist
Generates an increased level of braking force after the brake pedal is
depressed when the system detects a panic stop situation
◆VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning on
slippery road surfaces
◆TRAC (Traction Control)
Helps to maintain drive power and prevent the drive wheels from spinning
when starting the vehicle or accelerating on slippery roads
◆AUTO LSD function (2WD models)
The AUTO LSD function is activated when the system is in TRAC off
mode. It operates when one of the drive wheels is spinning, such as when
the wheel is spinning freely on ice or mud. The system applies the brakes
to the spinning wheel and transfers some of the torque to the other wheel
to secure drive power.
◆Hill-start assist control
Helps to reduce the vehicle from rolling backward when starting on an
incline
To help enhance driving safety and performance, the following
systems operate automatically in response to various driving
situations. Be aware, however, that these systems are supple-
mentary and should not be relied upon too heavily when operat-
ing the vehicle.

◆Dynamic Torque Control AWD system (AWD models)
Automatically switches from front-w heel drive to all-wheel drive (AWD)
according to the driving conditions, helping to ensure reliable handling and
stability. Examples of conditions where the system will switch to AWD are
when cornering, going uphill, starting off or accelerating, and when the
road surface is slippery due to snow, rain, etc.
◆EPS (Electric Power Steering)
Employs an electric motor to reduce the amount of effort needed to turn
the steering wheel
◆Trailer Sway Control (if equipped)
Helps the driver to control trailer sway by selectively applying brake pres-
sure for individual wheels and reducing engine torque when trailer sway is
detected.
Trailer Sway Control is part of the VSC system and will not operate if VSC
turned off or experiences a malfunction.
The slip indicator light will flash
while the TRAC/VSC/Trailer Sway
Control systems are operating.

■Reduced effectiveness of the EPS system
The effectiveness of the EPS system is reduced to prevent the system from
overheating when there is frequent steering input over an extended period of
time. The steering wheel may feel heavy as a result. Should this occur, refrain
from excessive steering input or stop the vehicle and turn the engine of\
f. The
EPS system should return to normal within 10 minutes.

WARNING
■The ABS does not operate effectively when
● The limits of tire gripping performance have been exceeded (such as
excessively worn tires on a snow covered road).
● The vehicle hydroplanes while driving at high speed on wet or slick roads.
■ Stopping distance when the ABS is operating may exceed that of nor-
mal conditions
The ABS is not designed to shorten the vehicle’s stopping distance. Always
maintain a safe distance from the vehicle in front of you, especially in the
following situations:
● When driving on dirt, gravel or snow-covered roads
● When driving with tire chains
● When driving over bumps in the road
● When driving over roads with potholes or uneven surfaces
■ TRAC may not operat e effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the TRAC system is operating.
Drive the vehicle carefully in conditions where stability and power may be
lost.
■ Hill-start assist control does not operate effectively when
● Do not overly rely on hill-start assist control. Hill-start assist control may
not operate effectively on steep inclines and roads covered with ice.
● Unlike the parking brake, hill-start assist control is not intended to hold the
vehicle stationary for an extended period of time. Do not attempt to use
hill-start assist control to hold the vehicle on an incline, as doing so may
lead to an accident.
■ When the VSC/Trailer Sw ay Control is activated
The slip indicator light flashes. Always drive carefully. Reckless driving may
cause an accident. Exercise particular care when the indicator light flashes.
■ When the TRAC/VSC/Trailer Sway Control systems ar e turned off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As these are the systems to help ensure vehicle stability and driving
force, do not turn the TRAC/VSC/Trailer Sway Control systems off unless
necessary.

WARNING
■Replacing tires
Make sure that all tires are of the specified size, brand, tread pattern and
total load capacity. In addition, make sure that the tires are inflated to the
recommended tire inflation pressure level.
The ABS, TRAC and VSC/Trailer Sway Control systems will not function
correctly if different tires are installed on the vehicle.
Contact your Toyota dealer for further information when replacing tires or
wheels.
■ Handling of tires and the suspension
Using tires with any kind of problem or modifying the suspension will affect
the driving assist systems, and may cause a system to malfunction.
■ Trailer Sway Control precaution
The Trailer Sway Control system is not able to reduce trailer sway in all situ-
ations. Depending on many factors such as the conditions of the vehicle,
trailer, road surface, and driving environment, the Trailer Sway Control sys-
tem may not be effective. Refer to your trailer owner’ manual for information
on how to tow your trailer properly.
■ If trailer sway occurs
Observe the following precautions.
Failing to do so may cause death or serious injury.
● Firmly grip the steering wheel. Steer straight ahead.
Do not try to control trailer swaying by turning the steering wheel.
● Begin releasing the accelerator pedal immediately but very gradually to
reduce speed.
Do not increase speed. Do not apply vehicle brakes.
If you make no extreme correction with the steering or brakes, your vehicle
and trailer should stabilize. ( →P. 192)
