Driving assist systems
To help enhance driving safety and performance, the following sys-
tems operate automatically in res ponse to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too h eavily when operating the vehicle.
■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 slippery 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 accelerating on slippery roads.
■Hill-start assist control
Helps prevent the vehicle from rolling backwards when starting on an
incline or slippery slope. The hill-start assist control only operate for 5
seconds when engaged.
■KDSS (Kinetic Dynamic Suspension System)
KDSS enhances 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.
■PCS (Pre-Collision System) (if equipped)

When the VSC/Active TRAC/hill-start assist control systems are
operatingIf the vehicle is in danger of slip-
ping, rolling backwards when
starting on an incline, or if the
rear wheels spin, the slip indica-
tor light flashes to indicate that
the VSC/Active TRAC/hill-start
assist control systems have
been engaged.
A buzzer (intermittent) sounds to
indicate that VSC is operating.
The stop lights and high mounted
stoplight turn on when the hill-
start assist control system is
operating.

■Active TRAC can be turned off when
The four-wheel drive control switch is in “H4” and the center differential is
unlocked.
■ Automatic reactivation of Active TRAC and VSC
Turning the “ENGINE START STOP” switch off after turning off the Active
TRAC and VSC systems will automatically re-enable them.
■ Automatic Active TRAC reactivation
If only the Active TRAC system is turned off, the Active TRAC system will
turn on when vehicle speed increases.
■ Automatic Active TRAC and VSC reactivation
If the Active TRAC and VSC systems are turned off, the systems will not turn
on even when vehicle speed.
■ If the brake system overheats
The Active TRAC and hill-start assist control will cease operation and a
buzzer will sound to alert the driver. Stop the vehicle in a safe place. (There
is no problem with continuing normal driving.)
■ Sounds and vibrations caused by the Multi Terrain ABS, brake assist,
Active TRAC, VSC and hill-start assist control
● 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 Multi Terrain ABS is acti-
vated.
• The brake pedal may move down slightly after the Multi Terrain ABS is activated.
■ Hill-start assist control is operational when
● The shift lever is in “D” or “S”.
● The brake pedal is not depressed.

CAUTION
Any of the following conditions may result in an accident which could cause
death or serious injury:
■The Multi Terrain ABS does no t operate effectively when
● The limits of tire gripping performance have been exceeded.
● The vehicle hydroplanes while driving at high speed on the wet or slick
road.
■ Stopping distance when the Multi Terrain ABS is operating on the wet
or slick roads
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 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 wi th 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 and VSC are off
Be especially careful and drive at a speed appropriate to the road condi-
tions. As there are systems to ensure vehicle stability and driving force, do
not turn off Active TRAC and VSC unless necessary.

CAUTION
■When the VSC is activated
The slip indicator light flashes and a warning buzzer sounds. Always drive
carefully.
Reckless driving may cause an accident. Exercise particular care when the
indicator light flashes and a buzzer sounds.
■ 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 speci-
fied tire pressure level.
The Multi Terrain ABS and VSC will not function correctly if different tires are
fitted on the vehicle.
Contact your Toyota dealer for further 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 malfunction.
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 imme-
diately.
● 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).

Pre-Collision System
: If equipped
■The pre-collision system is operational when
● Vehicle speed exceeds 19 mph (30 km/h).
● The system detects sudden braking or skidding.
● The front occupants are wearing a seat belt.
■ When there is a malfunction in the system
Warning message will be displayed on the multi-information display.
(
P. 523)
CAUTION
■Limitations of the pre-collision system
Do not rely on the pre-collision system. Always drive safely, taking care to
observe your surroundings and checki ng for any obstacles or other road
hazards.
The system detects emergency braking from the speed and force
with which the driver presses the brake pedal, and quickly tightens
the seat belt to improve the effectiveness of the seat belt pretension-
ers ( P. 73). This system also oper ates in the same manner when
the vehicle slips sideways.

Off-road precautions
Off-road vehicle feature● Specific design characteristics give it a higher center of gravity
than ordinary passenger cars. This vehicle design feature causes
this type of vehicle to be more likel y to rollover. And, utility vehicles
have a significantly higher rollover rate than other types of vehi-
cles.
● 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
passenger cars any more than low-slung sports cars are designed
to perform satisfactorily under of f-road conditions. Therefore, sharp
turns at excessive speeds may cause rollover.
This vehicle belongs to the utility vehicle class, which has higher
ground clearance and narrower 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.
