should not be working.
Installing electronic devices and
radios increases the risk of
cyber attacks through the
installed parts, which may lead
to unexpected accidents and
leakage of personal informa-
tion. Toyota does not make any
guarantees for problems caused
by installing non-genuine Toyota
products.
The installation of a mobile
two-way radio system in your
vehicle could affect electronic
systems such as:
Multiport fuel injection sys-
tem/sequential multiport fuel
injection system
 Toyota Safety Sense 3.0
 Anti-lock brake system
 SRS airbag system
 Seat belt pretensioner system
Be sure to check with your Toy-
ota dealer for precautionary
measures or special instructions
regarding installation of a mobile
two-way radio system. This vehicle is equipped with
sophisticated computers that
record certain data regarding
vehicle controls and operations.

Data recorded by the comput-
ers
*1
Certain data, such as the following,
is recorded dependi ng on the oper-
ation timing and status of each
function.
• Basic vehicle behavior related data (engine speed, accelera-
tor/brake pedal operation, vehi-
cle speed, etc.)
• Operating state of the driving support systems (recorded during
system operation, includes basic
vehicle behavior related data)
• Driving support system sensor data
• Image data (images from the front, rear and side cameras)
*2
• Location information
These computers do not record
conversations, sounds, or
images of the inside of the vehi-
cle.
Also, personal information which
may be used to identify the
owner of the vehicle (name,
gender, age, etc.) is not
recorded.
*1: The recorded data varies accord-
ing to the vehicle grade level and
options with which it is equipped.

WARNING
■Caution regarding interfer-
ence with electronic devices
●People with implantable car-
diac pacemakers, cardiac
resynchronization ther-
apy-pacemakers or implantable
cardioverter defib rillators should
keep away from the smart key
system antennas. ( P.120)
The radio waves may affect the
operation of such devices. If
necessary, the entry function
can be disabled. Ask your Toy-
ota dealer for details, such as
the frequency of radio waves
and timing of the emitted radio
waves. Then, consult your doc-
tor to see if you should disable
the entry function.
●Users of any electrical medical
device other than implantable
cardiac pacemakers, cardiac
resynchronization ther-
apy-pacemakers or implantable
cardioverter defibrillators should
consult the manufacturer of the
device for information about its
operation under the influence of
radio waves.
Radio waves could have unex-
pected effects on the operation
of such medical devices.
Ask your Toyota dealer for details
on disabling the entry function.

be heard and the brake pedal
response may change, but this
does not indicate a malfunction.
●When the system is operating, the
brake pedal may feel stiffer than
expected or sink. In either situa-
tion the brake pedal can be
depressed further. Further
depress the brake pedal as nec-
essary.
PCS (Pre-Collision Sys-
tem)
The pre-collision system
uses sensors to detect
objects ( P.191) in the path
of the vehicle. When the
system determines that the
possibility of a frontal colli-
sion with a detectable
object is high, a warning
operates to urge the driver
to take evasive action and
the potential brake pressure
is increased to help the
driver avoid the collision. If
the system determines that
the possibility of a collision
is extremely high, the
brakes are automatically
applied to help avoid the
collision or help reduce the
impact of the collision.
The pre-collision system
can be disabled/enabled
and the warning timing can
be changed. ( P.200)

Driving
■Intersection collision avoid-
ance support (crossing
vehicles)
At an intersection, etc., if the
system determines that the pos-
sibility of a collision with an
approaching vehicle or motorcy-
cle is high, the pre-collision
warning and pre-collision brak-
ing will operate.
Depending on the intersection,
assistance may not operate cor-
rectly.
■Acceleration Suppression
at Low Speed
When driving at a low speed, if
the accelerator pedal is strongly
depressed and the system
determines that there is a possi-
bility of a collision, engine output
will be restrained or the brakes
will be applied weakly to restrict acceleration. During operation,
a buzzer will sound and a warn-
ing indicator and message will
be displayed on the multi-infor-
mation display.
WARNING
■Pre-collision braking
●When the pre-collision braking
function is operating, a large
amount of braking force will be
applied.
●The pre-collision braking func-
tion is not desig
ned to hold the
vehicle stopped. If the vehicle is
stopped by pre-collision brake
control, the dri ver should oper-
ate the brakes immediately as
necessary.
●The pre-collision braking func-
tion may not operate if certain
operations are performed by the
driver. If the accelerator pedal is
being depressed strongly or the
steering wheel is being turned,
the system may determine that
the driver is taking evasive
action and possibly prevent the
pre-collision braking function
from operating.
●If the brake pedal is being
depressed, the system may
determine that t he driver is tak-
ing evasive action and possibly
delay the operation timing of the
pre-collision brake control.

Driving
The pre-collision setting can
be changed on the customize
settings. ( P.412)
 When the pre-collision warn-
ing timing is changed, the
emergency steering assist
(excluding the active steering
function) timing will also be
changed.
When "Later" is selected, the
emergency steering assist
(excluding the active steering
function) will not operate in
most cases.
 When the dynamic radar
cruise control is operating, the
pre-collision warning will
operate at the “Earlier” timing,
regardless of the user setting. 
When driving on a road with
clear lane lines with the
dynamic radar cruise control
operating, lane lines and pre-
ceding and surrounding vehi-
cles are detected using the
front camera and radar sen-
sor, and the steering wheel is
operated to maintain the vehi-
cle’s lane position.
Use the this function only on high-
ways and expressways.
If the dynamic radar cruise control
is not operating, the function will not
operate.
In situations where the lane lines
are difficult to see or are not visible,
such as when in a traffic jam, sup-
port will be provided using the path
of preceding and surrounding vehi-
cles.
If the system determines that the
steering wheel has not been oper-
ated for a certain amount of time or
the steering wheel is not being
firmly gripped, the driver will be
alerted via a display and this func-
tion will be temporarily canceled.
If the steering wheel is firmly
gripped, the func tion will begin
operating again.

●Outside/recirculated air mode may
automatically switch depending on
the temperature setting or the
inside temperature.
■When the outside temperature
falls to nearly 32°F (0°C)
The dehumidification function may
not operate even when “A/C” switch
is pressed.
■Ventilation and air conditioning
odors
●To let fresh air in, set the air condi-
tioning system to the outside air
mode.
●During use, various odors from
inside and outside the vehicle may
enter into and a ccumulate in the
air conditioning system. This may
then cause odor to be emitted
from the vents.
●To reduce potential odors from
occurring:
• It is recommended that the air
conditioning system be set to out-
side air mode prior to turning the
vehicle off.
• The start timing of the blower may be delayed for a short period of
time immediately after the air con-
ditioning system is started in auto-
matic mode.
●When parking, the system auto-
matically switches to outside air
mode to encourage better air cir-
culation throughout the vehicle,
helping to reduce odors that occur
when starting the vehicle.

■Warning performance of the tire
pressure warning system
●When performing the tire pressure
setting using the current tire infla-
tion pressure, the warning timing
of the tire pressure warning sys-
tem will vary according to the con-
ditions under which tire pressure
setting was performed. Therefore,
a warning may be output even if
the tire inflation pressure drops
slightly or if the ti re inflation pres-
sure increases above that when
the tire inflation pressure was set.
●Make sure to per form the tire
pressure setting p rocedure after
adjusting the tire inflation pres-
sure. Also, make sure the tires are
cold before performing the tire
pressure setting procedure or
adjusting the tire inflation pres-
sure.
