Voice Recognition
The Bluetooth system uses voice recognition
to interpret voice commands to dial phone
numbers and name tags.
For additional information, say“Help”while
you are in a voice recognition menu.
Noise : Keep interior noise levels to a
minimum. The system may not recognize
voice commands if there is too much
background noise.
When to Speak : A short tone sounds after
the system responds indicating when it is
waiting for a voice command. Wait until the
tone and then speak.
How to Speak : Speak clearly in a calm and
natural voice.
Audio System
When using the in-vehicle Bluetooth system,
sound comes through the vehicle's front
audio system speakers and overrides the
audio system. Use the audio system volume
knob, during a call, to change the volume
level. The adjusted volume level remains in
memory for later calls. To prevent missed
calls, a minimum volume level is used if the
volume is turned down too low.
Bluetooth Controls
Use the buttons on the steering wheel to
operate the in-vehicle Bluetooth system. See
Steering Wheel Controls 066.
b/g:Press to answer incoming calls,
confirm system information, and start
speech recognition.
c/x: Press to end a call, reject a call,
or cancel an operation.

paired to the Bluetooth system and then
connected to the vehicle before it can be
used. See the cell phone manufacturer's user
guide for Bluetooth functions before pairing
the cell phone.
Pairing Information

cannot be paired to the vehicle as a

same time.
.Up to five cell phones can be paired to
the Bluetooth system.
.The pairing process is disabled when the
vehicle is moving.
.Pairing only needs to be completed once,
unless the pairing information on the cell
phone changes or the cell phone is
deleted from the system.
.Only one paired cell phone can be
connected to the Bluetooth system at
a time.
.If multiple paired cell phones are within
range of the system, the system connects

the order that they were first paired to
the system. To connect to a different
paired phone, see “Connecting to a
Different Phone” later in this section.

4. Start the pairing process on the cell phone that you want to pair. For help
with this process, see the cell phone
manufacturer's user guide.
