1153-5. Tips for operating the navigation system
3
Navigation system
• When driving on a long straight road.
• When freeway and surface streets run in parallel.
• After moving by ferry or vehicle carrier.
• When a long route is searched during high speed driving.
• When driving without setting the current position calibration cor-
rectly.
• After repeating a change of direc- tion by going forward and back-
ward, or turning on a turntable in
a parking lot.
• When leaving a covered parking lot or parking garage.
• When a roof carrier is installed.
• When driving with tire chains installed.
• When the tires are worn.
• After replacing a tire or tires.
• When using tires that are smaller or larger than the factory specifi-
cations.
• When the tire pressure in any of the 4 tires is not correct.
 If the vehicle cannot receive
GPS signals, the current posi-
tion can be adjusted manu-
ally. For information on setting
the current position calibra-
tion: P. 1 0 8
 Inappropriate route guidance
may occur in the following
cases:
• When turning at an intersection
off the designated route guid-
ance. • If you set more than 1 destination
but skip any of them, auto reroute
will display a route returning to
the destination on the previous
route.
• When turning at an intersection for which there is no route guid-
ance.
• When passing through an inter- section for which there is no route
guidance.
• During auto reroute, the route guidance may not be available for
the next turn to the right or left.
• During high speed driving, it may take a long time for auto reroute
to operate. In auto reroute, a
detour route may be shown.
• After auto reroute, the route may not be changed.
• If an unnecessary U-turn is shown or announced.
• If a location has multiple names and the system announces 1 or
more of them.
• When a route cannot be searched.
• If the route to your destination includes gravel, unpaved roads or
alleys, the route guidance may
not be shown.
• Your destination point might be shown on the opposite side of the
street.
• When a portion of the route has regulations prohibiting the entry
of the vehicle that vary by time,
season or other reasons.
• The road and map data stored in the navigation system may not be
complete or may not be the latest

1474-6. Tips for operating the audio/visual system
4
Audio/visual system
Station interference: When a
reflected signal and a signal
received directly from a radio
station are very nearly the same
frequency, they can interfere
with each other, making it diffi-
cult to hear the broadcast.
Static: AM is easily affected by
external sources of electrical
noise, such as high tension
power lines, lightening or electri-
cal motors. This results in static.
■SiriusXM
 Cargo loaded on the roof lug-
gage carrier, especially metal
objects, may adversely affect
the reception of SiriusXM Sat-
ellite Radio.
 Alternation or modifications
carried out without appropri-
ate authorization may invali-
date the user’s right to
operate the equipment.
■Certification 

1565-1. Voice command system operation
5-1.Voice command system operation
■Steering switchTalk switch
Voice command system:
• Press the talk switch to start the voice command system. To can-
cel voice command, press and
hold the talk switch.
When an Apple CarPlay/Android
Auto connection is established:
• Press and hold the talk switch to start Siri/Google Assistant. To
cancel Siri/Google Assistant,
press the talk switch.
• Press the talk switch to start the voice command system.
■Microphone
 It is unnecessary to speak
directly into the microphone
when giving a command.
●Voice commands may not be rec-
ognized if:
• Spoken too quickly.
• Spoken at a low or high volume.
• The roof or windows are open.
• Passengers are talking while voice commands are spoken.
• The fan speed of the air condition-
ing system is set at high.
• The air conditioning vents are turned towards the microphone.
●In the following conditions, the
system may not recognize the
command properly and using
voice commands may not be pos-
sible:
• The command is incorrect or unclear. Note that certain words,
accents or speech patterns may
be difficult for the system to recog-
nize.
• There is excessive background
noise, such as wind noise.
●Normally, it is necessary to wait
for a beep before saying a com-
mand. To enable the ability to talk
over prompts and say commands
before the beep, enable the voice
prompt interrupt function. ( P. 6 4 )
●This system may not operate
immediately after the engine
switch is in ACC or ON.
Voice command sys-
tem
The voice command system
enables the radio, phone
dialing, etc. to be operated
using voice commands.
Refer to the command list
for samples of voice com-
mands. ( P.160)

1737-1. Rear view monitor system

Peripheral monitoring system
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.

■Microphone
The microphone is used when
talking on the phone.
●The other party’s voice will be
heard from the front speakers.
The audio/visual system will be
muted during phone calls or when
hands-free voice commands are
used.
●Talk alternately with the other
party on the phone. If both parties
speak at the same time, the other
party may not hear what has been
said. (This is not a malfunction.)
●Keep call volume down. Other-
wise, the other party’s voice may
be audible outside the vehicle and
voice echo may increase. When
talking on the phone, speak
clearly towards the microphone.
●The other party may not hear you
clearly when:
• Driving on an unpaved road. (Making excessive traffic noise.)
• Driving at high speeds.
• The roof or windows are open.
• The air conditioning vents are pointed towards the microphone.
• The sound of the air conditioning fan is loud.
• There is a negative effect on
sound quality due to the phone
and/or network being used.
