■Conditions in which the downhill assi st control system does not oper-
ate or will stop operating
● In the following situations, the downhill assist control system indicator
flashes and the downhill assist control system does not operate or will
stop operating:
• The shift lever is not in L or R.
• The vehicle speed is higher than 15 mph (25 km/h).
● If the accelerate or brake pedal is depressed, the downhill assist control
system will stop operating with the downhill assist control system indica-
tor stayed on.
■ If the “DAC” switch is turned off while the downhill assist control sys-
tem is operating
The downhill assist control system gradually ceases operation. The downhill
assist control system indicator will flash during the canceling operation, and
then go off when the system is fully off.
■ Downhill assist control system operation sound
●A sound may be heard from the engine compartment while the downhill
assist control system is operating. This sound does not indicate a mal-
function.
● If the accelerator or brake pedal is depressed while the downhill assist
control system is operating, a sound caused by the release of system
operation may be heard, or you may feel the brake pedal push-back. This
does not indicate a malfunction.
■ When the downhill assist contro l system operates continuously
The brake actuator may overheat. In that case, the downhill assist control
system will stop operating, a buzzer will sound and the downhill assist con-
trol system indicator will start flashing. Refrain from using the system until
the downhill assist control system indicator stays on. (There is no problem
with continuing driving normally.)
■ If the slip indicator comes on
It may indicate a malfunction in the system. Contact your Toyota dealer.

When driving
CAUTION
■Conditions which may affect the downhill assist control system opera-
tion
● Do not rely too heavily on the downhill assist control system. On extremely
steep inclines, icy surfaces or muddy roads, the vehicle may slip and the
system may not be able to maintain the constant low vehicle speed of
about 3 mph (5 km/h), leading to an accident causing death or serious
injury.
● Do not shift the shift lever to R while driving forward, or to D while driving
backward. Doing so may cause the wheels to lock up, leading to an acci-
dent causing death or serious injury. In addition, excessive stress will be
applied to the automatic transmission, possibly resulting in damage.

Four-wheel drive lock switch (4WD models)
■Four-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 START STOP” switch is in IGNITION ON mode.
■ Four-wheel drive lock mode
●Four-wheel drive lock mode is canceled when the brakes are applied to
ensure the ABS and VSC systems operate effectively.
● Four-wheel drive lock mode is canceled when the vehicle speed exceeds
25 mph (40 km/h).
Four-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.
Press the switch.
The torque of the engine is dis-
tributed to the rear wheels to
the maximum extent possible
in accordance with driving con-
ditions.
Pressing the switch again can-
cels four-wheel drive lock
mode and returns the Active
Torque Control 4WD system to
normal mode. (P. 184)

Utility vehicle 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 lo w-slung sports cars designed to
perform satisfactorily under off-r oad 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.

198 2-5. Driving information
CAUTION
■Off-road vehicle precautions
Always observe the following precautions to minimize the risk of serious per-
sonal 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.

When driving
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 minimize the risk of death or
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, water, 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.
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.
