●

It may be necessary at times to re-

calibrate the trailer to improve per-

formance.

●

The system is designed to be

used with the same trailer connec-

tion every time. If the ball mount

position is changed or reconfig-

ured or items are added to the

trailer tongue after calibration, re-

calibration may be required.

Guidance mode provides a
“Trailer Direction” arrow that
indicates the direction the trailer
will swing, based on calculations
from the steering wheel angle
information. Guidance mode
provides a “BRAKE Extreme
Trailer Angle” (jackknife) warn-
ing with warning buzzer to alert
the driver that the trailer angle is
near the jackknife condition.

Touch the switch at the bottom
right on multimedia to activate

Straight Path Assist. Straight
Pass Assist controls steering to
back up the trailer in a straight-
line. The system can be overrid-
den by using steering wheel to
adjust trailer direction.
The driver is always responsible
for paying attention to the vehi-
cle’s surroundings and driving
safely. This system does not
control braking. Driver needs to
control vehicle speed, control
braking, and stop the vehicle to
avoid any collision.
For best results, reverse slowly
when using Straight Path Assist.

WARNING

■

Cautions regarding the use of

the system

In order for this system to perform

as designed, the vehicle must be

driven safely and the driver must

control the speed to keep it within

operating parameters and to

avoid a collision.

As there is a limit to the degree of

control performance that this sys-

tem can provide, do not overly

rely on this system. The driver is

always responsible for paying

attention to the vehicle’s sur-

roundings and driving safely. This

system does not control braking

(or steering when in Guidance

mode). Driver needs to control

vehicle speed, control braking,

(and steering when in Guidance

mode,) and stop the vehicle to

avoid any collision. Failure to fol-

low this warning could result in

property damage, serious injury

or death.

■

When using the Trailer

Backup Guide

For proper system performance,

observe the following precautions.

Failure to do so may lead to an

accident resulting in property

damage, serious injury, or death.

●

Keep the tailgate fully latched.

●

Keep the rear camera clean at

all times.

●

Do not change the installation

position or direction of the rear

camera or remove it.

●

Do not modify the trailer hitch

light. (



Specific design characteris-
tics give it a higher center of
gravity than ordinary passen-
ger 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 corner-
ing at the same speeds as
ordinary passenger cars any
more than low-slung sports
cars are designed to perform
satisfactorily under off-road
conditions. Therefore, sharp
turns at excessive speeds
may cause the vehicle to roll-
over.

When driving your vehicle off-
road, please observe the follow-
ing precautions to ensure your
driving enjoyment and to help
prevent the closure of areas to

Off-road precautions

This vehicle belongs to the
utility vehicle class, which
has higher ground clear-
ance 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 pre-

cautions to minimize the risk of

death, serious injury or damage to

your vehicle:

●

In a rollover crash, an unbelted

person is significantly more

likely to die than a person wear-

ing 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 caus-

ing death or serious injury.

●

Avoid loading any items on the

roof that will raise the vehicle’s

center of gravity.

●

Always slow down in gusty

crosswinds. Because of its pro-

file and higher center of gravity,

your vehicle is more sensitive to

side winds than an ordinary

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 side-

ways much more easily than

forward or backward.

off-road vehicles:



Drive your vehicle only in
areas where off-road vehicles
are permitted 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 techniques should be
changed or travel delayed to
prevent damage to roads.

WARNING

■

Off-road driving precautions

Always observe the following pre-

cautions to minimize the risk of

death, serious 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 especially 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 wear-

ing a seat belt. Therefore, the

driver and all passengers

should fasten their seat belts

whenever the vehicle is moving.

●

When driving off-road or in rug-

ged 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 water damage

Take all necessary safety mea-

sures to ensure that water dam-

age 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 deterio-

ration in shift quality, locking up

of your transmission accompa-

nied by vibration, and ultimately

damage.

●

Water can wash the grease

from wheel bearings, causing

rusting and premature failure,

and may also enter the differen-

tials, 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. Press the Stop & Start

cancel switch to disable the Stop

& Start system. Drive slowly and

avoid deep water.

■

Inspection after off-road driv-

ing

●

Sand and mud that has accu-

mulated around brake discs

may affect braking efficiency

and may damage brake system

components.

●

Always perform a maintenance

inspection after each day of off-

road driving 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”.

406

4-6. Driving tips



Use fluids that are appropriate
to the prevailing outside tem-
peratures.

• Engine oil
• Engine coolant

to reduce the risk of accidents.

Failure to do so may result in a

loss of vehicle control and cause

death or serious injury.

●

Use tires of the specified size.

●

Maintain the recommended

level of air pressure.

●

Do not drive in excess of 75

mph (120 km/h), regardless of

the type of snow tires being

used.

●

Use snow tires on all, not just

some wheels.

●

4WD models: Do not mix tires of

different makes, models, tread

patterns or treadwear.

■

Driving with tire chains (vehi-

cles without 285/65R18 tires)

Observe the following precautions

to reduce the risk of accidents.

Failure to do so may result in the

vehicle being unable to be driven

safely, and may cause death or

serious injury.

●

Do not drive in excess of the

speed limit specified for the tire

chains being used, or 30 mph

(50 km/h), whichever is lower.

●

Assist) (if equipped) system.

407

4-6. Driving tips

ing

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 wind-
shield.



Check for and remove any
excess ice or snow that may
have accumulated 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 suit-
able to road conditions.



Park the vehicle and move
the shift lever to P without set-
ting 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 dan-
gerous because it may cause
the vehicle to move unexpect-
edly, 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 vehi-
cle inspected by your Toyota
dealer immediately.
