BLUETOOTH® HANDS-FREE
PHONE SYSTEM
WARNING
.Only use a phone after stopping your
vehicle in a safe location. If you have
to use a phone while driving, exercise
extreme caution at all times so full
attention may be given to vehicle
operation.
. If you find yourself unable to devote
full attention to vehicle operation
while talking on the phone, pull off
the road in a safe location and stop
your vehicle before doing so.
CAUTION
To avoid draining the vehicle battery
(12V battery), only use a phone after
starting the engine or the hybrid system.
Your vehicle is equipped with a 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 procedure for
connecting the phone does not need to be
performed again. Your phone is automati-
cally selected by the in-vehicle phone module
when the ignition switch is switched to the
ON position with the selected cellular phone
turned on and carried in the vehicle.
You can register up to five different Blue-
tooth® cellular phones to the in-vehicle
phone module. However, you can talk on
only one cellular phone at a time.
The Voice Recognition System supports
phone commands, so dialing a phone number
using your voice is possible.“7. Voice Recognition”
. Wireless LAN (Wi-Fi) and the Blue-
tooth® functions share the same fre-
quency band (2.4GHz). Using the
Bluetooth® and wireless LAN functions
at the same time may slow down or
disrupt communications and could cause
undesired noise. It is recommended that
you turn wireless LAN (Wi-Fi) off 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 Pone System.
. Some Bluetooth® enabled cellular
phones may not be recognized by the
in-vehicle phone module. Please visit
www.infinitiusa.com/bluetooth/search
for a recommended phone list.
. You will not be able to use a hands-free
phone under the following conditions:
— Your vehicle is outside the service area for your cellular phone network.
— 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.
— Your cellular phone is locked in order to prevent dialing.
. 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.
. This Bluetooth® system supports Wide-
band speech, which enhances the sound
quality of phone calls placed over Blue-
4-2

tooth®. To take advantage of this fea-
ture, the cellular device should be used
on a carrier supporting Adaptive Multi-
Rate Wideband (AMR-WB) or HD voice
technology. The performance of AMR-
WB may vary by carrier and calling area.
Consult your cellular phone carrier if you
experience issues with call quality or
connection.
. Immediately after the ignition switch is
turned ON, it may be impossible 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 of the cellular phone
may discharge quicker than usual.
. If the Bluetooth® Hands-Free Phone
System seems to be malfunctioning,
please visit www.infinitiusa.com/blue-
tooth for troubleshooting help.
. Some cellular phones or other devices
may cause interference or a buzzing
noise to be emitted from the audio system speakers. Storing the device in a
different location may reduce or elim-
inate the noise.
. Refer to the owner’s manual for the
cellular phone for information regarding
the telephone pairing procedure specific
to your phone, battery charging and
cellular phone antenna, etc.
. The antenna display on the monitor may
not match the antenna display of some
cellular phones.
. The battery display on the monitor may
not match the battery display of some
cellular phones.
. Keep the interior of the vehicle as quiet
as possible to her the caller’s voice clearly
as well as to minimize echoes.
. If reception between callers is unclear,
adjusting the incoming or outgoing call
volume may improve the clarity.CONTROL BUTTONS AND MI-
