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.

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.

When using Eco drive mode, the
torque corresponding to the
accelerator pedal depression
amount can be generated more
smoothly than it is in normal
conditions. In addition, the oper-
ation of the air conditioning sys-
tem (heating/cooling) will be
minimized, improving the fuel
economy. ( P.358)
The Eco-friendly driving is pos-
sible by keeping the indicate of
Hybrid System Indicator within
Eco area. ( P.97)
Shift the shift lever to D when
stopped at a traffic light, or driv-
ing in heavy traffic etc. Shift the
shift lever to P when parking.
When using the N, there is no
positive effect on fuel consump-
tion. When using the air condi-
tioning system, etc., the hybrid
battery (traction battery) power
is consumed. 
Drive your vehicle smoothly.
Avoid abrupt acceleration and
deceleration. Gradual accel-
eration and deceleration will
make more effective use of
the electric motor (traction
motor) without having to use
gasoline engine power.
 Avoid repeated acceleration.
Repeated acceleration con-
sumes hybrid battery (trac-
tion battery) power, resulting
in poor fuel consumption. Bat-
tery power can be restored by
driving with the accelerator
pedal slightly released.
Make sure to operate the brakes
gently and in a timely manner. A
greater amount of electrical
energy can be regenerated
when slowing down.
Repeated acceleration and
deceleration, as well as long
waits at traffic lights, will lead to
bad fuel economy. Check traffic
reports before leaving and avoid
delays as much as possible.
When driving in a traffic jam,
gently release the brake pedal
to allow the vehicle to move for-
ward slightly while avoiding

off-road vehicles:
Drive your vehicle only in
areas where off-road vehicles
are permitted 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 techniques should be
changed or travel delayed to
prevent damage to roads.
■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
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.
