Trailer brake TYPE selection button
Trailer brake type can be selected by pressing the trailer brake TYPE
selection button on the trailer brake controller. Trailer brake TYPE selec-
tion button will cycle through electric trailer brake and electric-over-
hydraulic trailer brakes. The combination meter will show which trailer
brake type is selected in the multi-information display after pressing the
trailer brake TYPE selection button.
Manual TRAILER BRAKE OUTPUT slider
Adjusting this slider position will engage the trailer’s brakes only. If the
manual TRAILER BRAKE OUTPUT slider is used while the vehicle
brake is applied, the greater of the two outputs will be sent to the trailer
brakes.
Gain setting on trailer brake controller should be set for a specific tow-
ing condition. Gain setting should be adjusted each time the vehicle
load, trailer load, road conditions, or weather changes. Setting the
gain value to 0 will disable the trailer brake controller output.
Make sure the trailer brakes are in good working condition and
functioning normally. See trailer dealer if necessary.
Hook up the trailer and make proper electrical connections.
With trailer brake TYPE selec-
tion button, select the correct
type of trailer brakes that are
equipped on the trailer.
Drive vehicle with trailer attached on a level road surface similar to
towing condition and in traffic-free environment. Driving speed
should be approximately 20 - 25 mph [35 - 40 km/h].
Using the GAIN (+/-) selection
buttons, set a starting gain of
5.0.

2424-5. Using the driving support systems
While driving 20 - 25 mph [35 - 40 km/h], fully apply the manual
TRAILER BRAKE OUTPUT
slider.
Adjust the gain setting, using the GAIN (+/-) selection buttons, to
either increase or decrease to just below the point of trailer wheel
lock-up.
For confirmation, repeat steps and until desired gain setting
is reached (just below point of trailer wheel lock-up).
■ When using the trailer brake control system
Please turn off the intuitive parking assist while towing a trailer. If left on,
sonar sensors will detect the trailer being towed.
■ 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 allowable setting for the towing
condition.
■ When disconnecting and reco nnecting battery terminals
The gain setting data will be reset.
CAUTION
■ Trailer brake type setting
It is the responsibility of the driver to make sure the trailer brakes are func-
tioning normally and adjusted appropriately. Failure to check and maintain
trailer brakes may result in loss of vehicle control, crash, or serious injury.
Trailer brake control system will work with most electric and electric-over-
hydraulic trailer braking systems up to 3 axles (24A output to trailer brakes).
Please be sure to test compatibility with the system at low speeds and in a
safe area. When a warning message appears in the multi-information dis-
play (P. 483), the gain setting may be too high. Please use the trailer
brakes with reduced gain. If there is still a problem, have the vehicle
inspected by your Toyota dealer immediately.
Some electric-over-hydraulic trailer brakes will take some minimum output
to activate. Trailer brake control system will not work with trailer hydraulic
surge brakes.
■ When driving on slippery road surfaces
When stopping with ABS activated, output to the trailer might be reduced in
order to reduce the likelihood of trailer to sway or trailer wheels to lock. The
trailer is not equipped with ABS. Drive safely on slippery road surfaces.

Off-road precautions
●Specific design char acteristics give it a higher center of gravity than
ordinary passenger cars. This vehi cle 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 are designed to
perform satisfactorily under off -road conditions. Therefore, sharp
turns at excessive speeds may c ause the vehicle to rollover.
This vehicle belongs to the util ity vehicle class, which has
higher ground clearance and narrowe r 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.
Off-road vehicle features

2484-6. Driving tips
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 trav el delayed to prevent damage to
roads.
CAUTION
■ 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.
● 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 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.

■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, 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.
● 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.

2504-6. Driving tips
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.
■ 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 river bed 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”.
