2017 TOYOTA TUNDRA trailer

2444-5. 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 settin g, 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. 485), 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.
