CHECKING PROCEDURE
To prevent inaccurate or false readings, make sure there is no refrigerant vapor, shop chemicals, or cigarette
smoke in the vicinity of the vehicle. Perform the leak test in calm area (low air/wind movement) so that the
leaking refrigerant is not dispersed.
1. Stop the engine.
2. Connect a suitable A/C manifold gauge set (SST: J-39183) to the A/C service valves.
3. Check if the A/C refrigerant pressure is at least 345 kPa (3.52 kg/cm
2 , 50 psi) above 16°C (61°F). If less
than specification, recover/evacuate and recharge the system with the specified amount of refrigerant.
NOTE:
At temperatures below 16°C (61°F), leaks may not be detected since the system may not reach 345 kPa
(3.52 kg/cm
2 , 50 psi).
4. Perform the leak test from the high-pressure side (compressor discharge a to evaporator inlet h) to the
low-pressure side [evaporator drain hose i to shaft seal m(VQ35DE) or n(VK45DE)]. Refer to ATC-152,
"Components" . Perform a leak check for the following areas carefully. Clean the component to be
checked and move the leak detected probe completely around the connection/component.
Compressor
Check the fitting of high- and low-pressure flexible hoses, relief valve and shaft seal.
Condenser
Check the fitting of high-pressure flexible hose and pipe.
Liquid tank
Check the fitting of refrigerant pressure sensor.
Service valves
Check all around the service valves. Ensure service valve caps are secured on the service valves (to pre-
vent leaks).
NOTE:
After removing A/C manifold gauge set from service valves, wipe any residue from valves to prevent any
false readings by leak detector.
Cooling unit (Evaporator)
With engine OFF, turn blower fan on “High” for at least 15 seconds to dissipate any refrigerant trace in the
cooling unit. Wait a minimum of 10 minutes accumulation time (refer to the manufacturer’s recommended
procedure for actual wait time) before inserting the leak detector probe into the drain hose.
Keep the probe inserted for at least 10 seconds. Use caution not to contaminate the probe tip with water
or dirt that may be in the drain hose.
5. If a leak detector detects a leak, verify at least once by blowing compressed air into area of suspected
leak, then repeat check as outlined above.
6. Do not stop when one leak is found. Continue to check for additional leaks at all system components.
If no leaks are found, perform steps 7 - 10.
7. Start the engine.
8. Set the A/C control as follows;
a. A/C switch: ON
b. MODE door position: VENT (Ventilation)
c. Intake door position: Recirculation
d. Temperature setting: Max. cold
e. Fan speed: High
9. Run engine at 1,500 rpm for at least 2 minutes.
10. Stop the engine and perform leak check again following steps 4
through 6 above.
Refrigerant leaks should be checked immediately after stopping
the engine. Begin with the leak detector at the compressor. The
pressure on the high-pressure side will gradually drop after
refrigerant circulation stops and pressure on the low-pressure
side will gradually rise, as shown in the graph. Some leaks are
more easily detected when pressure is high.

SYSTEM DESCRIPTION
Revision: 2007 April2007 M35/M45
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
SKIB1058E

AV-10
[WITHOUT MOBILE ENTERTAINMENT SYSTEM]
SYSTEM DESCRIPTION
Revision: 2007 April2007 M35/M45

Map-matching does not function correctly when a road on which
the vehicle is driving is new and not recorded in the map DVD-
ROM, or when road pattern stored in the map data and the
actual road pattern are different due to repair.
When driving on a road not present in the map, the map-match-
ing function may find another road and position the vehicle mark
on it. Then, when the correct road is detected, the vehicle mark
may change to it.

Effective range for comparing the vehicle position and travel
direction calculated by the distance and direction with the road
data read from the map DVD-ROM is limited. Therefore, when
there is an excessive gap between current vehicle position and
the position on the map, correction by map-matching is not possible.
GPS (Global Positioning System)
GPS (Global Positioning System) was developed for and is con-
trolled by the US Department of Defense. The system utilizes GPS
satellites (NAVSTAR), sending out radio waves while flying on an
orbit around the earth at an altitude of approximately 21,000 km
(13,100miles).
The GPS receiver calculates the vehicle's position in three dimen-
sions (latitude/longitude/altitude) according to the time lag of the
radio waves received from four or more GPS satellites (three-dimen-
sional positioning). If radio waves were received only from three
GPS satellites, the GPS receiver calculates the vehicle's position in
two dimensions (latitude/longitude), utilizing the altitude data calcu-
lated previously with radio waves from four or more GPS satellites
(two-dimensional positioning).
Position correction by GPS is not available while the vehicle is stopped.
Accuracy of GPS will deteriorate under the following conditions:

In two-dimensional positioning, GPS accuracy will deteriorate when altitude of the vehicle position
changes.

The accuracy can be even lower depending on the arrangement of the GPS satellites utilized for the posi-
tioning.

Position detection is not possible when vehicle is in an area where radio waves from the GPS satellite do
not reach, such as in a tunnel, parking lot in a building, and under an elevated highway. Radio waves from
the GPS satellites may not be received when some object is located over the GPS antenna.
NOTE:

Even a high-precision three dimensional positioning, the detection result has an error about 10 m (30 ft).

Because the signals of GPS satellite is controlled by the Tracking and Control Center in the United States,
the accuracy may be degraded lower intentionally or the radio waves may stop.
HANDS-FREE PHONE

AV (NAVI) control unit has Bluetooth module. It can perform wireless hands-free telephone calls using a
cellular phone in vehicle compartment.

5 or more portable phones can be registered into the AV (NAVI) control unit.
REAR VIEW MONITOR

The small CCD camera is equipped into the rear end of the vehicle. The rear view monitor that displays
the area behind the vehicle while backing up is equipped.

Guiding lines indicating side and rear clearances are provided in the rear view monitor image, which
allows the driver to more easily judge distances between the vehicle and objects in the display. The possi-
ble route lines that indicate the possible route according to the steering angle are provided to help backing
up when parking.

Image quality of the rear view image and of the navigation screen can be adjusted separately.
