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 fixed 
guide lines on the screen and 
the actual distance/course on 
the road.
NOTICE
• 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.

screen and the actual 
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.■When the ground behind 
the vehicle slopes down 
sharply
The distance guide lines will 
appear to be farther from the 
vehicle than the actual distance. 
Because of this, objects will 
appear to be closer 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.

■When any part of the vehi-
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.
A margin of error
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.

On the screen, it appears that a

However, in reality if you back 
up to point  , you will hit the

●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 Blue-
tooth® 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 Blue-
tooth
® 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. 1 6 )
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 Blue-
tooth
®. Bluetooth® is a wire-
less 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.
*
*: This function is not available in  some countries or areas.

●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. The temperature 
inside may rise to a level that 
could damage the phone.
