2. 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 connected by a cable or
placed in a cradle.
The operating procedure of the phone is
explained here.
CAUTION
● While driving, do not use a cellular phone
or connect the Bluetooth® phone.
● Your audio unit is fitted with Bluetooth
®
antennas. People with implantable car-
diac pacemakers, cardiac
resynchronization therapy-pacemakers
or implantable cardioverter defibrillators
should maintain a reasonable 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 pacemakers,
cardiac resynchronization therapy-pace-
makers or implantable cardioverter
defibrillators should consult the manufac-
turer of the device for information about
its operation under the influence of radio
waves. Radio waves could have unex-
pected 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.
INFORMATION
● 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 com-
munication area.
• The cellular phone is not connected.
• The cellular phone has a low battery.
● When using Bluetooth
® audio and
hands-free system at the same time, the
following problems may occur:
• The Bluetooth
® connection may be cut.
• Noise may be heard on the Bluetooth
®
audio playback.
