tial lock system
Failure to obser ve the following
precautions may result in an acci-
dent.
●Do not lock the rear differential
in the conditions other than
above.

Crawl Control*
Allows travel on extremely
rough off-road surfaces at a
fixed low speed without
pressing the accelerator or
brake pedal. Minimizes loss
of traction or vehicle slip
when driving on slippery
road surfaces, allowing for
stable driving.
WARNING
■When using Crawl Control
function
Do not rely solely on the Crawl
Control function. This function
does not extend the vehicle’s per-
formance limitatio ns. Always thor-
oughly check the road conditions,
and drive safely.
■These conditions may cause
the system not to operate
properly
When driving on the following sur-
faces, the system may not be able
to maintain a fixed low speed,
which may result in an accident:
●Extremely steep inclines.
●Extremely uneven surfaces.
●Snow-covered roads, or other
slippery surfaces.

“GAIN” (+/-) selection button
Pressing the “GAIN” (+/-) buttons
will adjust the amount of power that
can be outputted to the trailer
brakes. The “gain” can be adjusted
from 0 (no trailer braking) to 10
(maximum output) in 0.5 incre-
ments. Each press of the button will
increase or decrease the “gain” set-
ting by one step. The “gain” value
will appear in the mu lti-information
display.
Trailer brake type
Trailer brake type can be selected
by using the multi-information. The
combination meter will show which
trailer brake type is selected in the
multi-information display.
Manual brake slider
Adjusting this slider position will
engage the trailer’s brakes only. If
the manual brake slider is used
while the vehicle brake is applied,
the greater of the two outputs will
be sent to the trailer brakes.
Trailer brake control-
ler
The trailer brakes can be
controlled by the Trailer
brake controller via the 7-
pin connector. By selecting
the type of brakes that are
being used on the trailer
(electric or electric-over-
hydraulic) and setting the
“gain” for the controller, the
manual brake slider is used
to slow just the trailer. The
vehicle brake pedal will also
slow down as well as stop
the trailer when applied,
also via the same connec-
tor. “Gain” values, manual
brake outputs, trailer brake
types, and the trailer con-
nection status are displayed
in the multi-information dis-
play.
WARNING
■When driving on slippery
road surfaces
When stopping with ABS acti-
vated, output to the trailer might
be reduced in order to reduce the
likelihood of trailer wheels to lock.
The trailer is not equipped with
ABS. Drive safely on slippery road
surfaces.

tion.
“Gain” setting on trailer brake
controller should be set for a
specific towing 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. 1

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

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.519), 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.
