tions.
Failing to do so ma y result in the
vehicle being unable to be driven
safely and possibly cause an acci-
dent.
●Do not use the sensor at
speeds in excess of 6 mph (10
km/h).
●The sensors’ detection areas
and reaction times are limited.
When moving forward or revers-
ing, check the areas surround-
ing the vehicle (especially the
sides of the vehicle) for safety,
and drive slowly, using the
brake to control the vehicle’s
speed.
●Do not install accessories within
the sensors’ detection areas.

*: If equipped
■Parking Support Brake
function (static objects) (if
equipped)
Ultrasonic sensors are used to
detect static objects, such as a
wall, in the detection area when
driving at a low speed or back-
ing up. ( P.296)
PKSB (Parking Sup-
port Brake)*
The Parking Support Brake
system consists of the fol-
lowing functions that oper-
ate when driving at a low
speed or backing up, such
as when parking. When the
system determines that the
possibility of a collision
with a detected object is
high, a warning operates to
urge the driver to take eva-
sive action. If the system
determines that the possi-
bility of a collision with a
detected object is extremely
high, the brakes are auto-
matically applied to help
avoid the collision or help
reduce the impact of the col-
lision.

WARNING
●Do not replace a sensor with a
part other than a genuine part.
●Do not subject a sensor or its
surrounding area to a strong
impact.
●Do not damage the sensors,
and always keep them clean.
●If the area around a radar sen-
sor is subjected to an impact,
the system may not operate
properly due to a sensor mal-
function. Have the vehicle
inspected by your Toyota
dealer.
■Handling the suspension
Do not modify the suspension, as
changes to the height or inclina-
tion of the vehicle may prevent
the sensors from detecting
objects correctly or cause the sys-
tem to not operate or operate
unnecessarily.
■If the Parking Support Brake
function (static objects) oper-
ates unnecessarily, such as
at a railroad crossing
In the event that the Parking Sup-
port Brake function (static objects)
operates unnecessarily, such as
at a railroad crossing, brake con-
trol will be cancel ed after approxi-
mately 2 seconds, allowing you to
proceed forward and leave the
area, brake control can also be
canceled by depressing the brake
pedal. Depressing the accelera-
tor pedal after brake control is
canceled will allow you to proceed
forward and leave the area.
■Notes when washing the vehi-
cle
Do not apply intensive bursts of
water or steam to the sensor
area.
Doing so may result in the sensor
malfunctioning.
●When using a high pressure
washer to wash the vehicle, do
not spray the sensors directly,
as doing so may cause a sensor
to malfunction.
●When using steam to clean the
vehicle, do not direct steam too
close to the sensors as doing so
may cause a sensor to malfunc-
tion.
■When to disable the Parking
Support Brake
In the following situations, disable
the Parking Support Brake as the
system may operate even though
there is no possibility of a colli-
sion.
●When inspecting the vehicle
using a chassis roller, chassis
dynamo or free roller
●When loading the vehicle onto a
boat, truck or other transport
vessel
●If the suspension has been
modified or tires of a size other
than specified are installed
●If the front of the vehicle is
raised or lowered due to the
carried load
●When equipment that may
obstruct a sensor is installed,
such as a towing eyelet, bumper
protector (an additional trim
strip, etc.), bicycle carrier, or
snow plow
●When using an automatic car

lem or modifying the suspension
will affect the driving assist sys-
tems, and may cause a system to
malfunction.
■Trailer Sway Control precau-
tion
The Trailer Sway Control system
is not able to reduce trailer sway
in all situations. Depending on
many factors such as the condi-
tions of the vehicle, trailer, road
surface and driving environment,
the Trailer Sway Control system
may not be effect ive. Refer to
your trailer owner’s manual for
information on how to tow your
trailer properly.
■If trailer sway occurs
Observe the following precau-
tions.
Failing to do so may cause death
or serious injury.
●Firmly grip the steering wheel.
Steer straight ahead. Do not try
to control trailer sway by turning
the steering wheel.
●Begin releasing the accelerator
pedal immediately but very
gradually to reduce speed.
Do not increase speed. Do not
apply vehicle brakes.
If you make no extreme correction
with the steering or brakes, your
vehicle and trailer should stabi-
lize. (
