Driving assist systems
◆Multi Terrain 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 sl ippery road surface, or in off-road
conditions (such as rough roads, sand and mud)
◆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
◆Active TRAC (Traction Control)
Helps to maintain drive power and prevent the 4 wheels from spinning
when starting the vehicle or accelerati ng on slippery roads, or in off-road
conditions
◆Hill-start assist control
Helps to reduce the backward movement of the vehicle when starting on
an incline or slippery slope
◆KDSS (Kinetic Dynamic Suspension System)
KDSS helps to enhance ride comfort and handling response by using a
hydraulic control system to control the suspension stabilizer bars in
response to road surface and driving conditions during cornering or off-
road driving
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.

◆VGRS (Variable Gear Ratio Steering)
Helps to adjust the wheel turning angle in accordance with the vehicle
speed and steering wheel movement.
◆Trailer Sway Control
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 flashes to
indicate that the VSC/Trailer
Sway Control/Active TRAC/hill-
start assist control systems have
been engaged.
The stop lights and high mounted
stoplight turn on when the hill-start
assist control system or Trailer
Sway Control is operating.

will not turn on even when vehicle speed increases.
■ If the brake system overheats
The brake system may overheat. In this case, a buzzer will sound, and the
TRAC OFF indicator will flash, and Acti ve TRAC and hill-start assist control
will be temporarily inoperable. In this event, stop the vehicle immediately in a
safe place, and allow the brake system to cool down sufficiently until the
TRAC OFF indicator go off. (There is no problem with continuing normal driv-
ing.)
■ Sounds and vibrations caused by the Multi Terrain ABS, brake assist,
Active TRAC, VSC, Trailer Sway Co ntrol, hill-start assist control and
VGRS
● 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 indicate
that a malfunction has occurred in any of these systems.
● Any of the following conditions may occur when the above systems are

WARNING
Any of the following conditions may result in an accident which could cause
death or serious injury:
■The Multi Terrain 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 the wet or slick
road.
■ Stopping distance when the Multi Terrain ABS is operating may exceed
that of normal conditions
The Multi Terrain ABS is not designed to shorten the vehicle’s stopping dis-
tance. 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 roads
■ Active TRAC may not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the Active TRAC is operating.
Do not drive the vehicle in conditions where stability and power may be lost.
■ If the hill-start assist contro l does not operate effectively
Do not overly rely on the hill-start assist control. The hill-start assist control
may not operate effectively on steep inclines and roads covered in ice.
■ When Active TRAC, VSC and Trailer Sway Control are off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As there are systems to help ensure vehicle stability and driving force,
do not turn off Active TRAC, VSC and Trailer Sway Control unless neces-
sary.

WARNING
■When the VSC and Trailer Sway Control are activated
The slip indicator light flashes. Always drive carefully.
Reckless driving may cause an accident. Exercise particular care when the
indicator light flashes.
■
Replacing tires
Make sure that all tires are of the same size, brand, tread pattern and
total load capacity. In addition, make sure that the tires are inflated to
the specified tire pressure level.
The Multi Terrain ABS, Active TRAC, VSC and Trailer Sway Control will
not function correctly if differen t tires are fitted on the vehicle.
Contact your Toyota dealer for furt her information when replacing tires
or wheels.
■Handling of tires and suspension
Using tires with any kind of problem or modifying the suspension will
affect the driving assist systems, and may cause the system to malfunc-
tion.
■ 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’s manual for informa-
tion 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. 195)

NOTICE
■KDSS
In the following situations, there is the possibility that a system malfunction
has occurred, and drive comfort and the vehicle’s ability to travel on poor
road surfaces may be reduced. Take the vehicle to your Toyota dealer
immediately.
● When turning a corner, the vehicle’s body seems to roll further than nor-
mal.
● If after the vehicle has been left in a slanted position for a long time, for
example with the wheels of one side parked on a curb, the vehicle does
not return to level when driving (the vehicle remains slanted to one side
after returning the vehicle to level ground).

Off-road precautions
●Specific design char acteristics give it a higher center of gravity than
ordinary passenger cars. This vehi cle design feature causes this
type of vehicle to be more likely to rollover. And, utility vehicles
have a significantly higher rollover rate than other types of vehicles.
● An advantage of the higher ground clearance is a better view of the
road allowing you to anticipate problems.
● It is not designed for cornering at the same speeds as ordinary pas-
senger cars any more than low- slung sports cars are designed to
perform satisfactorily under off -road conditions. Therefore, sharp
turns at excessive speeds may c ause the vehicle to rollover.
This vehicle belongs to the util ity vehicle class, which has
higher ground clearance and narrowe r tread in relation to the
height of its center of gravity to make it capable of performing in
a wide variety of off-road applications.
