2016 TOYOTA TUNDRA wheel

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.

2444-6. Driving tips
Park the vehicle and move the shift lever to P without setting the park-
ing brake. The parking brake may fr eeze up, preventing it from being
released. If necessary, block the wheels to prev ent inadvertent sliding
or creeping.
Observe the following precautions when switching fuels, in order to
maintain starting and driving performance.
● Do not change fuels when the fuel level is 1/4 or less.
● Always add at least 2.6 gal. (10 L) of fuel.
● After filling up with fuel, warm up the engine or drive the vehicle for
at least 5 minutes or 7 miles (11 km).
● Do not accelerate rapidly immediately after refueling.
Use the correct tire chain size when mounting the tire chains.
Chain size is regulated for each tire size.
Side chain
(0.2 in. [5 mm] in diameter)
Cross chain
(0.25 in. [6.3 mm] in diameter)
Regulations regarding the use of tire chains vary depending on loca-
tion and type of road. Al ways check local regulations before installing
chains.

■Tire chain installation
Observe the following precautions when installing and removing chains:
●Install and remove tire chains in a safe location.
● Install tire chains on the rear tires. Do not install tire chains on the front tires.
● Install tire chains on rear tires as tightly as possible. Retighten chains after
driving 1/4  1/2 mile (0.5  1.0 km).
● Install tire chains following the instructions provided with the tire chains.
CAUTION
■ Driving with snow tires
Observe the following precautions 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
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.
● Avoid driving on bumpy road surfaces or over potholes.
● Avoid sudden acceleration, abrupt steering, sudden braking and shifting
operations that cause sudden engine braking.
● Slow down sufficiently before entering a curve to ensure that vehicle con-
trol is maintained.

■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”.
