Your vehicle is equipped with Bluetooth®
Hands-Free Phone System. If you are an
owner of a compatible Bluetooth® enabled
cellular phone, you can set up the wireless
connection between your cellular phone and
the in-vehicle phone module. With Blue- tooth® wireless technology, you can make
or receive a telephone call with your cellular
phone in your pocket.
Once a cellular phone is connected to the in-
vehicle phone module, the procedures for
connecting the phone does not need to be
performed again. Your phone will automati-
cally re-connect to the in-vehicle phone
module when the ignition switch is placed
in the ACC or ON position with the selected
cellular phone turned on and carried in the
vehicle.
You can register up to 6 different Blue-
tooth® devices in the in-vehicle phone
module. However, you can talk on only one
cellular phone at a time.
The Voice Recognition System supports
phone and text message commands, so
dialing a phone number using your voice is
possible.“7. Voice recognition”
Before using the Bluetooth® Hands-Free
Phone System, refer to the following notes. . Wireless LAN (Wi-Fi) and the Blue-
tooth® functions share the same fre-
quency band (2.4 GHz). Using the
Bluetooth® and the wireless LAN func-
tions at the same time may slow down or disconnect the communication and cause
undesired noise. It is recommended that
you turn off the wireless LAN (Wi-Fi) (if
so equipped) when using the Bluetooth®
functions.
. Set up the wireless connection between
a compatible cellular phone and the in-
vehicle phone module before using the
Bluetooth® Hands-Free Phone System.
. Some Bluetooth® enabled cellular
phones may not be recognized by the
in-vehicle phone module. Visit the web-
site below for a recommended phone list.
www.infinitiusa.com/bluetooth/
. When Apple CarPlay® or Android Auto
is active, Apple CarPlay® or Android
Auto will take the place of your Blue-
tooth® Hands-Free Phone functionality.
. You will not be able to use a hands-free
phone under the following conditions:
— Your vehicle is outside of the tele- phone service area.
— Your vehicle is in an area where it is difficult to receive radio waves; such
as in a tunnel, in an underground
parking garage, behind a tall building
or in a mountainous area.
4-2

— Your cellular phone is locked in orderto prevent dialing.
. If Apple CarPlay® or Android Auto is
active, the Bluetooth® Hands-Free
Phone cannot be used.
. When the radio wave condition is not
ideal or ambient sound is too loud, it may
be difficult to hear the other person’s
voice during a call.
. Immediately after the ignition switch is
placed in the ACC or ON position, it may
not be possible to receive a call for a
short period of time.
. Do not place the cellular phone in an area
surrounded by metal or far away from
the in-vehicle phone module to prevent
tone quality degradation and wireless
connection disruption.
. While a cellular phone is connected
through the Bluetooth® wireless con-
nection, the battery power of the cellular
phone may discharge quicker than usual.
. Visit the website below for trouble-
shooting help if the Bluetooth® Hands-
Free Phone System seems to be mal-
functioning.
www.infinitiusa.com/bluetooth/ .
Some cellular phones or other devices
may cause interference or a buzzing
noise to come from the audio system
speakers. Storing the device in a differ-
ent location may reduce or eliminate the
noise.
. Refer to the cellular phone Owner’s
Manual regarding the telephone pairing
procedure specific to your phone, bat-
tery charging, cellular phone antenna,
etc.
. The antenna or battery display on the
monitor may not coincide with the
antenna or battery display of some
cellular phones.
. If reception between callers is unclear,
adjusting the incoming or outgoing call
volume may improve the clarity.
“Volume and Beeps settings”

optimized to recognize the driver’s voice.
Speech from vehicle passengers may not
be captured by the Bluetooth® Hands-
Free Phone System. .
Keep the interior of the vehicle as quiet
as possible to hear the caller’s voice

BLUETOOTH® HANDS-FREE PHONE SYSTEM
SymptomPossible cause Possible solution
A cellular phone cannot be registered. The cellular phone is not compatible with the in- vehicle Hands-Free Phone System. Use a cellular phone compatible with the system. Visit
www.infinitiusa.com/bluetooth/ to check compat-
ibility.
Registration of the cellular phone has been
performed incorrectly. Check the registration procedure, and then register
the cellular phone again.
A cellular phone cannot be connected or is
disconnected after the registration is
completed. The Bluetooth® setting of the in-vehicle Hands-
Free Phone System is turned off.
Turn on the Bluetooth® setting of the system.
The Bluetooth® setting of the cellular phone is
turned off. Turn on the Bluetooth® setting of the cellular phone.
The remaining battery level of the cellular phone
is low. Charge the battery of the cellular phone.
The wireless Bluetooth® connection may be
disrupted depending on the location of the
cellular phone. Do not place the cellular phone in an area surrounded
by metal or far away from the in-vehicle Hands-Free
Phone System. Do not place the cellular phone close
to the seats or your body.
Registration of the cellular phone is not com-
pleted. Perform registration of the cellular phone.
A call to a particular phone number fails. If the system tries to make a call several times to the same phone number (for example: the party
does not respond to the call, the party is out of
the service area, or the call is abandoned before
the party responds), the system may reject a
request to make a call to the phone number. Turn off the cellular phone and turn it on again to
reset the connection.
8. Troubleshooting guide
8-15

SymptomPossible cause Possible solution
When a cellular phone is operated to make
a call, the hands-free function becomes
unavailable. Some models of a cellular phone do not switch
to the hands-free mode when they are operated
to make a call. This is not a malfunction. Make another call using the
hands-free function.
The other party’s voice cannot be heard.
There is no ringtone. The volume level is set to the minimum. Adjust the volume level.
“Volume and Beeps settings” (page 2-32)
A cellular phone is not connected. Check the registration procedure, and then register the cellular phone again.
Each volume level (ringtone, incoming voice
or outgoing voice) is different. Each volume level is not adjusted properly. Adjust each volume level properly.
The antenna display and remaining battery
level are different between the touch
screen display and a cellular phone screen.
Making or receiving a call is unavailable
even though the antenna display shows
that it is possible to do so. The antenna display varies depending on the
model of cellular phone.
This does not indicate a malfunction. The antenna
display and remaining battery level shown on the
touch screen display may be different from those
shown on the cellular phone screen. Use them as a
reference.
A voice cannot be heard clearly when using
a cellular phone behind tall buildings. Some structures such as tall buildings, etc. may
cause irregular reflection of radio waves or
completely shut out radio waves that are used
for cellular phones. Move to a place without tall buildings.
Noise is heard when using a cellular phone
under/near areas of elevated railroads,
high voltage electric power cables, traffic
signals, neon billboards, etc. Electromagnetic waves that are generated from
radio devices may adversely affect the cellular
phone.
This is not a malfunction.
Noise is heard in the sound from the audio
system while using a cellular phone. Radio waves that are generated from a cellular
phone may adversely affect the sound from the
audio system. This is not a malfunction.
Sound skips or stutters. The cellular phone may have turned on the wireless LAN (Wi-Fi). Turn off the wireless LAN (Wi-Fi).
