excessively worn tires on a snow covered road).

●

The vehicle hydroplanes while driving at high speed on wet or slick road.

■

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:

●

WARNING

■

When the TRAC/VSC/Trailer Sway Control systems is 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.

■

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, Trailer Sway Control and VSC 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’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. (

Off-road precautions

● 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 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 designed to per-
form satisfactorily under off-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.

WARNING

■

Off-road vehicle precautions
Always observe the following precautions to minimize the risk of death, seri-
ous 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 always fasten their seat belts.

●

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.

●

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.

●

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 your vehicle off-road, please observe the following pre-
cautions to ensure your driving enjoyment and to help prevent the clo-
sure of areas to off-road vehicles:
● Drive your vehicle only in areas where 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 travel delayed to prevent damage to
roads.

WARNING

■

Off-road driving precautions
Always observe the following precautions to minimize the risk of death, seri-
ous 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.

●

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.

NOTICE

■

To prevent 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.

■

When you drive through water
If driving through water, such as when crossing shallow streams, first check
the depth of the water and the bottom of the riverbed for firmness. Drive
slowly and avoid deep water.

■

Inspection after off-road driving

●

Sand and mud that has accumulated in brake drums and around brake
discs may affect braking efficiency and may damage brake system compo-
nents.

●

Always perform a maintenance inspection after each day of off-road driv-
ing that has taken you through rough terrain, sand, mud, or water. For
scheduled maintenance information, refer to the “Scheduled Maintenance
Guide” or “Owner’s Manual Supplement”.

● Use fluids that are appropriate to the prevailing outside tempera-

tures.

• Engine oil
• Engine coolant
• Washer fluid

● Have a service technician inspect the condition of the battery.
● Have the vehicle fitted with four snow tires or purchase a set of tire

chains for the rear tires.

Ensure that all tires are the same size and brand, and that chains match
the size of the tires.

Carry out the necessary preparations and inspections before
driving the vehicle in winter. Always drive the vehicle in a man-
ner appropriate to the prevailing weather conditions.

Perform the following according to the driving conditions:
● Do not try to forcibly open a window or move a wiper that is frozen.

Pour warm water over the frozen area to melt the ice. Wipe away
the water immediately to prevent it from freezing.

● To ensure proper operation of the climate control system fan,

remove any snow that has accumulated on the air inlet vents in
front of the windshield.

● Check for and remove any excess ice or snow that may have accu-

mulated on the exterior lights, vehicle’s roof, chassis, around the
tires or on the brakes.

● Remove any snow or mud from the bottom of your shoes before

getting in the vehicle.

Accelerate the vehicle slowly, keep a safe distance between you and
the vehicle ahead, and drive at a reduced speed suitable to road con-
ditions.

● Park the vehicle and move the shift lever to P without setting the

parking brake. The parking brake may freeze up, preventing it from
being released. If the vehicle is parked without setting the parking
brake, make sure to block the wheels.
Failure to do so may be dangerous because it may cause the vehi-
cle to move unexpectedly, possibly leading to an accident.

● If the vehicle is parked without setting the parking brake, confirm

that the shift lever cannot be moved out of P

: The shift lever will be locked if it is attempted to be shifted from P to any

other position without depressing the brake pedal. If the shift lever can be
shifted from P, there may be a problem with the shift lock system. Have the
vehicle inspected by your Toyota dealer immediately.
