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 roads with pothol es or roads with 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
The hill-start assist control may not operate effectively on steep inclines and
roads covered in ice.

■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.
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. 511)
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. 74). 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.

214 2-5. Driving information
L/C200_U
CAUTION
■Off-road vehicle precautions
Always observe the following precautions to help minimize the risk of serious
personal injury or damage to your vehicle:
● In a rollover crash, an unbelted person is significantly more likely to die
than a person wearing a seat belt. Therefore, the driver and all passengers
should fasten their seat belts whenever the vehicle is moving.
● Avoid sharp turns or abrupt maneuvers, if at all possible.
Failure to operate this vehicle correctly may result in loss of control or
vehicle rollover causing death or serious injury.
● Loading cargo on the roof luggage carrier will make the center of the vehi-
cle gravity higher. Avoid high speeds, sudden starts, sharp turns, sudden
braking or abrupt maneuvers, otherwise it may result in loss of control or
vehicle rollover due to failure to operate this vehicle correctly.
● Always slow down in gusty crosswinds. Because of its profile and higher
center of gravity, your vehicle is more sensitive to side winds than an ordi-
nary passenger car. Slowing down will allow you to have better control.
● Do not drive horizontally across steep slopes. Driving straight up or
straight down is preferred. Your vehicle (or any similar off-road vehicle)
can tip over sideways much more easily than forward or backward.

Off-road driving
When driving your vehicle off-road, please observe the following pre-
cautions to ensure your driving enjoyment and to help prevent the
closure of areas to off-road vehicles.
● Drive your vehicle only in areas wh ere off-road vehicles are permit-
ted to travel.
● Respect private property. Get owner’s permission before entering
private property.
● Do not enter areas that are closed. Honor gates, barriers and signs
that restrict travel.
● Stay on established roads. When conditions are wet, driving tech-
niques should be changed or trav el delayed to prevent damage to
roads.
■ Additional information for off-road driving
For owners in U.S. mainland, Hawaii and Puerto Rico:
To obtain additional information pertaining to driving your vehicle off-road,
consult the following organizations.
● State and Local Parks and Recreation Departments
● State Motor Vehicle Bureau
● Recreational Vehicle Clubs
● U.S. Forest Service and Bureau of Land Management

CAUTION
■Off-road driving precautions
Always observe the following precautions to help minimize the risk of serious
personal injury or damage to your vehicle:
● Drive carefully when off the road. Do not take unnecessary risks by driving
in dangerous places.
● Do not grip the steering wheel spokes when driving off-road. A bad bump
could jerk the wheel and injure your hands. Keep both hands and espe-
cially your thumbs on the outside of the rim.
● Always check your brakes for effectiveness immediately after driving in
sand, mud, water or snow.
● After driving through tall grass, mud, rock, sand, rivers, etc., check that
there is no grass, bush, paper, rags, stone, sand, etc. adhering or trapped
on the underbody. Clear off any such matter from the underbody. If the
vehicle is used with these materials trapped or adhering to the underbody,
a breakdown or fire could occur.
● When driving off-road or in rugged terrain, do not drive at excessive
speeds, jump, make sharp turns, strike objects, etc. This may cause loss
of control or vehicle rollover causing death or serious injury. You are also
risking expensive damage to your vehicle’s suspension and chassis.
