SYSTEM DESCRIPTION
Component Parts
Mode door control system components are:
Unified meter and A/C amp.
Mode door motor (LCU)
A/C LAN system (PBR built-in mode door motor, upper ventilator door motor, air mix door motor and
intake door motor)
In-vehicle sensor
Ambient sensor
Sunload sensor
Intake sensor
System Operation
The unified meter and A/C amp. receives data from each of the sensors. The unified meter and A/C amp.
sends air mix door, mode door, upper ventilator door and intake door opening angle data to the air mix door
motor LCU, mode door motor LCU, upper ventilator door motor LCU and intake door motor LCU.
The air mix door motor, mode door motor, upper ventilator door motor and intake door motor read their respec-
tive signals according to the address signal. Opening angle indication signals received from the unified meter
and A/C amp. and each of the motor position sensors are compared by the LCUs in each door motor with the
existing decision and opening angles. Subsequently, HOT/COLD, DEF/VENT, OPEN/SHUT and FRE/REC
operation is selected. The new selection data are returned to the unified meter and A/C amp.

WAR NING :
Avoid breathing A/C refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose and
throat. Remove HFC-134a (R-134a) from A/C system using certified service equipment meeting
requirements of SAE J-2210 [HFC-134a (R-134a) recycling equipment] or J-2209 [HFC-134a (R-134a)

SYSTEM DESCRIPTIONPFP:00000
System FunctionsNKS00489
Here is an example of functions. For details, refer to the owner's manual or navigation system owner's manual.
AUDIO
Speed Sensitive Volume (for BASE System)
Volume level of this system gone up and down automatically in proportion to the vehicle speed. And the
control level can be selected by the customer.
The audio unit inputs the vehicle signal that is sent from unified meter and A/C amp via CAN communica-
tion through AV (NAVI) control unit.
Precision Phased Audio (for BASE System)
It plays back the sound using the woofer (ultra-low bass and clear midrange sound) and reproduces the
sound with presence.
When the conventional BASS/TREBLE adjustment is a maximum, the sounds might be unclear because
the volume of midrange sound also rises together with the bass and treble. The precision phased audio
can emphasize ultra-low bass and ultra-high treble without changing the midrange sound by digital pro-
cessing using DSP.
NOTE:
When the radio is played, the noise may increase more than the presence due to the characteristics of
broadcasting waves. Therefore, the amplification rate while playing the radio is controlled lower than the
rate while playing CD.
AudioPilot® (for BOSE System)
AudioPilot® is the sound improving system that picks up any noises and the sound of music coming into the
vehicle by a microphone under the steering, and that the BOSE amp revises the frequency feature of music at
real time in response to the frequency feature of the noise while driving and listening to music.
If low frequency area noise from vehicle is loud, it adjusts low frequency element of music to be bigger
than vehicle noise.
If high frequency area noise from vehicle is loud, it adjusts all frequency element of music to be bigger
than vehicle noise.
Centerpoint® (for BOSE Surround 5.1ch System)
CD and 2.0ch DVD stereo sound played at audio unit and DVD player are subjected to signal processing in
BOSE amp. It can play the surround sound with presence.
VEHICLE INFORMATION SYSTEM
The status of audio, climate control system, fuel consumption, and navigation system (if equipped) are
displayed.
AV (NAVI) control unit receives the data signal from ECM, unified meter and A/C amp and low tire pres-
sure warning control unit via CAN communication. It calculates the values of fuel economy, tire pressure,
and trip computer from the received information and displays them.
NAVIGATION SYSTEM
Location Detection Principle
The navigation system periodically calculates the vehicle's current
position according to the following three signals:
Travel distance of the vehicle as determined by the vehicle
speed sensor
Turning angle of the vehicle as determined by the gyroscope
(angular velocity sensor)
Direction of vehicle travel as determined by the GPS antenna
(GPS information)
The current position of the vehicle is then identified by comparing the
calculated vehicle position with map data read from the map DVD-
ROM, which is stored in the DVD-ROM drive (map-matching), and

REAR VIEW MONITOR
An indirect route is suggested.If there are restrictions (such as one way streets)
on roads close to the starting point or destination,
the system may suggest an indirect route.Adjust the location of the starting point or
destination.
The system may suggest an indirect route because
route calculation does not take into consideration
some areas such as narrow streets (gray roads).Reset the destination to a main or ordinary
road, and recalculate the route.
The landmark information does not
correspond to the actual informa-
tion.This may caused by insufficient or incorrect data on
the DVD-ROM.This is not a malfunction.
The suggested route does not
exactly connect to the starting
point, waypoints, or destination.There is no data for route calculation closer to
these locations.Set the starting point, waypoints and desti-
nation on main road, and perform route cal-
culation. Symptom Possible cause Possible solution
Symptom Possible cause Possible solution
The voice guidance is not avail-

The vehicle has deviated from the suggested
route.Go back to the suggested route or request
route calculation again.
Voice guidance is set to off. Turn on the voice guidance.
Route guidance is set to off. Turn on the voice guidance.
The guidance content does not

the command.
The system recognizes the com-
mand incorrectly.The interior of the vehicle is too noisy.Close the windows or have other occu-
pants be quiet.
The volume of the voice is too low. Speak louder.
Pronunciation is unclear. Speak clearly.
Voice recognition mode is not yet ready to speak.Push the release “PTT” on the steering
switch, and speak a command after the
tone sounds.
5 seconds or more have passed after pushed and
released “PTT” on the steering switch.Make sure to speak a command within
5seconds after push and release “PTT” on
the steering switch.
Only a limited range of voice commands is usable
for each screen.Use a correct voice command appropriate
for the current screen.

(GPS information)
The current position of the vehicle is then identified by comparing the
calculated vehicle position with map data read from the map DVD-
ROM, which is stored in the DVD-ROM drive (map-matching), and
indicated on the screen as a vehicle mark. More accurate data is judged and used by comparing vehicle posi-
tion detection results found by the GPS with the result by map-matching.
The current vehicle position will be calculated by detecting the dis-
tance the vehicle moved from the previous calculation point and its
direction.
Travel distance
Travel distance calculations are based on the vehicle speed
sensor input signal. Therefore, the calculation may become
incorrect as the tires wear down. To prevent this, an automatic
distance correction function has been adopted.
Travel direction
Change in the travel direction of the vehicle is calculated by a
gyroscope (angular velocity sensor) and a GPS antenna (GPS
information). They have both advantages and disadvantages.
