The distance guide lines and the vehicle width guide lines
may not actually be parallel
with the dividing lines of the
parking space, even when
they appear to be so. Be sure
to check visually.
 The distances between the
vehicle width guide lines and
the left and right dividing lines
of the parking space may not
be equal, even when they
appear to be so. Be sure to
check visually.
 The distance guide lines give
a distance guide for flat road
surfaces. In any of the follow-
ing situations, there is a mar-
gin of error between the guide
lines on the screen and the
actual distance/course on the
road.
■When the ground behind
the vehicle slopes up
sharply
The distance guide lines will
appear to be closer to the vehi-
cle than the actual distance.
Because of this, objects will
appear to be farther away than
they actually are. In the same
way, there will be a margin of
error between the guide lines
and the actual distance/course
on the road.
NOTICE
●The rear view monitor system
may not operate properly in the
following cases.
• If the back of the vehicle is hit, the position and mounting angle
of the camera may change.
• As the camera has a water proof construction, do not
detach, disassemble or modify
it. This may cause incorrect
operation.
• When cleaning the camera lens, flush the camera with a large
quantity of water and wipe it
with a soft and wet cloth.
Strongly rubbing the camera
lens may cause the camera lens
to be scratched and unable to
transmit a clear image.
• Do not allow organic solvent, car wax, window cleaner or a
glass coating to adhere to the
camera. If this happens, wipe it
off as soon as possible.
• If the temperature changes rap- idly, such as when hot water is
poured on the vehicle in cold
weather, the system may not
operate normally.
• When washing the vehicle, do not apply intensive bursts of
water to the camera or camera
area. Doing so may result in the
camera malfunctioning.
●Do not expose the camera to
strong impact as this could
cause a malfunction. If this hap-
pens, have the vehicle
inspected by your Toyota dealer
as soon as possible.

The distance guide lines will
appear to be farther from the

between the guide lines and the

cle sags
When any part of the vehicle
sags due to the number of pas-
sengers or the distribution of the
load, there is a margin of error
between the fixed guide lines on
the screen and the actual dis-
tance/course on the road.

Peripheral monitoring system
The distance guide lines are dis-
played according to flat surfaced
objects (such as the road). It is
not possible to determine the
position of three-dimensional
objects (such as vehicles) using
the vehicle width guide lines and
distance guide lines. When
approaching a three-dimen-
sional object that extends out-
ward (such as the flatbed of a
truck), be careful of the follow-
ing.
■Vehicle width guide lines
Visually check the surroundings
and the area behind the vehicle.
In the case shown below, the
truck appears to be outside of
the vehicle width guide lines and
the vehicle does not look as if it
hits the truck. However, the rear
body of the truck may actually
cross over the vehicle width
guide lines. In reality if you back
up as guided by the vehicle
width guide lines, the vehicle
may hit the truck. Vehicle width guide lines

●This system is not guaranteed to
operate with all Bluetooth®
devices.
●If your cellular phone does not
support Bluetooth®, this system
cannot function.
●In the following conditions, the
system may not function:
• The cellular phone is turned off.
• The current position is outside the
communication area.
• The cellular phone is not con-
nected.
• The cellular phone has a low bat- tery.
●Depending on the type of
Bluetooth® phone, some function
is not available.
●When using the hands-free sys-
tem or Bluetooth® audio and
Wi-Fi® hotspot functions at the
same time, the following problems
may occur:
• The Bluetooth
® connection may
be cut.
• Noise may be heard on the
Bluetooth
® audio playback.
• A noise may be heard during phone calls.
●Bluetooth® uses the 2.4 GHz fre-
quency band. If both a Wi-Fi® con-
nection and Bluetooth®
connection are being used simul-
taneously, each connection may
be affected.
●If a Bluetooth® device is attempt-
ing to connect to the vehicle while
another device is connected as a
Bluetooth
® audio device or con-
nected using the hands-free sys-
tem or Wi-Fi
® hotspot function,
the communication speed may
decrease or malfunctions may
occur, such as image distortion or
audio skipping. If a Bluetooth
®
device is connected to the system,
the interference it may cause will
be reduced. When carrying a
device with its Bluetooth
® connec-
tion enabled, make sure to regis-
ter it to the system and connect it
or disable its Bluetooth
® function.
●When a device is connected via
Bluetooth®, the Bluetooth® icon
on the status bar will be displayed
in blue. ( P.11)
Some basics
The hands-free system
enables calls to be made
and received without having
to take your hands off the
steering wheel.
This system supports
Bluetooth
®. Bluetooth® is a
wireless data system that
enables cellular phones to
be used without being con-
nected by a cable or placed
in a cradle.
The operating procedure of
the phone is explained here.
When an Apple CarPlay
connection is established,
phone functions will be per-
formed by Apple CarPlay
instead of the hands-free
system.
WARNING
●While driving, do not operate a
cellular phone.

1226-1. Phone operation (Hands-free system for cellular phones)

WARNING
●Your audio unit is fitted with
Bluetooth® antennas. People
with implantable cardiac pace-
makers, cardiac resynchroniza-
tion therapy-pacemakers or
implantable cardioverter defibril-
lators should maintain a reason-
able distance between
themselves and the Bluetooth
®
antennas. The radio waves may
affect the operation of such
devices.
●Before using Bluetooth®
devices, users of any electrical
medical device other than
implantable cardiac pacemak-
ers, cardiac resynchronization
therapy-pacemakers or implant-
able cardioverter defibrillators
should consult the manufacturer
of the device for information
about its operation under the
influence of radio waves. Radio
waves could have unexpected
effects on the operation of such
medical devices.
NOTICE
●Do not leave your cellular phone
in the vehicle. T he temperature
inside may rise to a level that
