HANDS-FREE PHONE FUNCTION
 AV control unit includes hands-free phone function.
 Hands-free communication can be oper ated by connecting using Bluetooth
™ communication with cellular
phone.
 Operation is performed by steering switch, and operating condition is indicated on display.
 Guide sound that is heard during operation is input fr om AV control unit to BOSE amp., and is output from
front speaker and center speaker.
When A Call Is Originated
Spoken voice sound output from the microphone (microphone signal ) is input to AV control unit. AV control unit
outputs to cellular phone with Bluetooth
™ communication as a TEL voice signal. Voice sound is then heard at
the other party.
When Receiving A Call
Voice sound is input to own cellular phone from the other party. TEL voice signal is output to door speaker, and
the signal is input to BOSE amp. via AV control unit by establishing Bluetooth
™ communication from cellular
phone.
TOUCH PANEL SYSTEM
Each operation of multi AV system can be perfo rmed by directly touching a front display.
AROUND VIEW MONITOR FUNCTION
 This system is equipped with wide-angle high-resolution cameras on the front and rear of the vehicle and on
both right and left door mirrors. The images from front view, rear view, front-side view (RH side), and birds-
eye view that shows the view from the top of the vehicle are displayed to monitor the vehicle surroundings.
 Around view monitor control unit cuts out and expands the image received from each camera to create each view.
 The sonar indicator is displayed on display (superimposed on the camera image) in combination with the
camera assistance sonar system to warm of the approach of an obstacle.
 In front view and rear view, the vehicle width, dist ance lines and predictive course lines are superimposed
and displayed. In front-side view, the vehicle distance guiding line and vehicle width guiding line are dis-
played.
 The Birds-Eye view converts the images from 4 cameras into the overhead view and displays the status of
the vehicle on display. The vehicle icon and sonar indica tor that are displayed on the Birds-Eye view display
are rendered by around view monitor control unit.
Around View Monitor Screen
 Around view monitor combines and displays the travel di rection view and “Birds-Eye view”, “Front-Side view”
and then it displays the sonar indicator on the “Birds -Eye view”, “Front-Side view”, “Rear wide view”.
 AV control unit renders the “Change View” switch, view icon, warning message on display.

REMOVAL
1. Pull headlining assembly (rear). Obtain a service area. Refer to INT-28, "Exploded View".
2. Disconnect antenna feeder connector.
3. Remove nut, and remove satellite radio antenna and the cover from the vehicle as a single unit.
INSTALLATION
Install in the reverse order of removal.
CAUTION:
If the satellite radio ante nna mounting nut is tightened looser than the specified torque, then this will
lower the sensitivity of the antenna. On the other hand, if the nut is tightened tighter than the specified
torque, then this will deform the roof panel.
Disassembly and AssemblyINFOID:0000000006362353
DISASSEMBLY
Insert cloth-covered driver into gaps between satel lite radio antenna and the cover, and remove the cover from
satellite radio antenna.
ASSEMBLY
Assemble in the reverse order of disassembly.

INTELLIGENT BRAKE ASSIST
INTELLIGENT BRAKE ASSIST : System DescriptionINFOID:0000000006228299
FUNCTION DESCRIPTION
Intelligent Brake Assist (IBA) syst
em warns the driver by a vehicle ahead detection indicator and chime when
there is a risk of a collision with the vehicle ahead in the traveling lane and the driver must take avoidance
action immediately. The system helps reduce the rear -end collision speed by applying the brakes when it
judges a collision can not be avoided.
CAUTION:
The IBA system is a not collision avoidance system. It is the driver ′s responsibility to stay alert, drive
safely and be in control of the vehicle at all times. As there is a performance limit, it may not provide a
warning or brake in certain conditions.
NOTE:
 The IBA system shares component parts and diagnosis wi th the Intelligent Cruise Control (ICC) system.
New parts added to the IBA system is the IBA OFF indica tor lamp in the combination meter and the IBA OFF
switch on the instrument driver lower panel.
 The ICC sensor integrated unit shares the parts with the ICC, but the IBA system will operate even when the
ICC system is turned to OFF.
OPERATION DESCRIPTION
The IBA system uses an ICC sensor located below t he front bumper to measure the distance to a vehicle
ahead. When the system judges that the distance gets shorter, the vehicle ahead detection indicator on the
combination meter blinks and the warning chime sounds.
To turn the system OFF/ON, push and hold the IBA OFF switch after starting the engine for more than 1 sec-
ond.
NOTE:
 The system ON/OFF condition will be memorized even if the ignition switch turns OFF.
 The IBA system operates under the following conditions.
- The IBA system will function when the vehicle is driv en at speeds of approximately 15 km/h (10 MPH) and
above, and when the vehicle ′s speed is approximately 15 km/h (10 MPH) faster than that of the vehicle
ahead.
