8 For confirmation, repeat
steps 6 and 7 until desired
“gain” setting is reached (just
below point of trailer wheel
lock-up).
■When setting the “gain”
Wheel lock-up occurs when the
trailer wheel squeals or tire smoke
occurs. Trailer wheels may not lock-
up while driving heavily loaded
trailer. During this case, adjust the
Trailer “gain” to the highest allow-
able setting for the towing condition.
■When disconnecting and recon-
necting 12-volt battery termi-
nals
The “gain” setting data will be reset.
■Trailer Sway Control Function
Helps suppress trailer sway at an
early stage by using the trailer brake
control system to operate the trailer
brakes.
■If the Trailer brake warning light
comes on
Indicates a malfunction in the Trailer
brake control system or Trailer con-
nector circuit.
Have the vehicle inspected by your
Toyota dealer immediately.
WARNING
■Trailer brake type setting
It is the responsibility of the driver
to make sure the trailer brakes
are functioning normally and
adjusted appropriately. Failure to
check and maintain trailer brakes
may result in loss of vehicle con-
trol, crash, or serious injury.
Trailer brake control system will
work with most electric and elec-
tric-overhydraulic trailer braking
systems up to 3 axles (24A output
to trailer brakes). Please be sure
to test compatibility with the sys-
tem at low speeds and in a safe
area. If a warning message
appears in the multi-information
display ( P.511), have the vehi-
cle inspected by your Toyota
dealer immediately. Some elec-
tric-over-hydraulic trailer brakes
will take some minimum output to
activate. Trailer brake control sys-
tem will not work with trailer
hydraulic surge brakes.

●The system is designed to support
most trailers 6.6 ft. (2 m) to 26.2 ft.
(8 m) in length (length is defined
from the coupler c enter point for
the ball to the wheel axle [single
axle] or center o f the wheel axles
[2 or more axles]) with ball mount
lengths between 4.5 in. (114.3
mm) and 18.5 in. ( 469.9 mm). Do
not attempt to use trailers or ball
mounts that have a length outside
of this range as t he system perfor-
mance degrades and could cause
improper system function. Trailer length

●For best calibration results, cali-
brate in daytime on a smooth and
level road.
●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.

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 tailgat e 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. (→P.386)
●Make sure nothing can obstruct
the rear camera view of the
trailer.
The system is designed to oper-
ate in various weather and lighting
conditions and on different ground
surfaces (asphalt , grass, gravel,
etc.), however performance can
still be affected by various envi-
ronmental factors (e.g. shadow
passing over the tr ailer or dimin-
ished contrast between trailer and
the ground leading to trailer
detection being lost, etc.) so
always drive carefully, remain
alert and aware of your surround-
ings, and do not overly rely on the
system.

 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 t he following pre-
cautions to minim ize 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 operat e 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 ce nter 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.

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 ou tside 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.

Driving
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.
When the parking brake is in auto-
matic mode, release the parking
brake after shifting the shift lever to
P. ( P.206)
 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
NOTICE
■Repairing or replacing snow
tires
