SYSTEM DIAGRAM
AUDIO SYSTEM
The audio system consists of the following components
• Audio unit
• Front door speakers
• Rear door speakers
• Steering wheel audio control switches
• Antenna base (antenna amp.)
• Rod antenna
When the audio system is on, AM/FM signals received
by the rod antenna are amplified by the antenna amp.
and sent to the audio unit. The audio unit then sends audio signals to the front door speakers and rear door
speakers.
Refer to Owner's Manual for audio system operating instructions.
HANDS-FREE PHONE SYSTEM
System Operation
NOTE:
Cellular telephones must have their wireless connec tion set up (paired) before using the Bluetooth
® telephone
system.
The Bluetooth
® telephone system allows users who have a Bluetooth® cellular telephone to make a wireless
connection between their cellular telephone and the Bluetooth
® control unit. Hands-free cellular telephone
calls can be sent and received. Some Bluetooth
® cellular telephones may not be recognized by the Bluetooth®
control unit. When a cellular telephone or the Bluetooth® control unit is replaced, the telephone must be paired
with the Bluetooth
® control unit. Different cellular telephones may have different pairing procedures, refer to
the cellular telephone operating manual.
Refer to the Owner's Manual for Bluetooth
® telephone system operating instructions.
Bluetooth® Control Unit
When the ignition switch is turned to ACC or ON, the Bluetooth® control unit will power up. During power up,
the Bluetooth
® control unit is initialized and performs various self-checks. Initialization may take up to 20 sec-
onds.
Steering Wheel Audio Control Switches
When buttons on the steering wheel audio control switches are pushed, the resistance in steering wheel audio
control switch circuit changes, depending on which button is pushed.
The following functions can be performed using the steering wheel audio control switches:
• Initiate self-diagnosis of the Bluetooth
® telephone system
• Answer and end telephone calls
