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

®
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

Bluetooth®, this system cannot function.
● In the following conditions, the system
may not function:

• The current position is outside the com-
munication area.
