SYSTEM DESCRIPTION
Revision: 2006 January2006 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.

MOBILE ENTERTAINMENT SYSTEM
The wireless headphone has been adopted to the rear seat. It is possible to listen to a separate sound in
front seat and rear seat and to see a separate image in front display and rear display.
When headphone mode is turned ON at radio/CD changer mode, AUX or DVD mode is turned ON only for
rear seat. The image that is different from front seat is displayed and a separate sound is output from
speaker and headphone.

AV (NAVI) control unit has a Bluetooth module. It can perform wireless hands-free telephone calls using
the portable phone in a pocket.
5 or more portable phones can be registered into the AV (NAVI) control unit.

DESCRIPTION
All dimensions indicated in the figures are actual.
When using a tracking gauge, adjust both pointers to equal length. Then check the pointers and gauge
itself to make sure there is no free play.
When a measuring tape is used, check to be sure there is no elongation, twisting or bending.
Measurements should be taken at the center of the mounting holes.
An asterisk (*) following the value at the measuring point indicates that the measuring point on the other
side is symmetrically the same value.
The coordinates of the measurement points are the distances measured from the standard line of X, Y
and Z.

3. Attach liquid gasket tube to the tube presser [SST: WS39930000
(—)].
Use Genuine RTV Silicone Sealant or equivalent. Refer to
GI-48, "
RECOMMENDED CHEMICAL PRODUCTS AND
SEALANTS" .
4. Apply liquid gasket without breaks to the specified location with
the specified dimensions.
If there is a groove for the liquid gasket application, apply liq-
uid gasket to the groove.
As for the bolt holes, normally apply liquid gasket inside the
holes. Occasionally, it should be applied outside the holes.
Make sure to read the text of service manual.
Within five minutes of liquid gasket application, install the mat-
ing component.
If liquid gasket protrudes, wipe it off immediately.
Do not retighten after mounting bolts and nuts the installation.
After 30 minutes or more have passed from the installation, fill
engine oil and engine coolant.
CAUTION:
If there are specific instructions in this manual, observe them.

LIQUID GASKET APPLICATION PROCEDURE
1. Using a scraper, remove old liquid gasket adhering to the liquid
gasket application surface and the mating surface.
Remove liquid gasket completely from the groove of the liquid
gasket application surface, mounting bolts, and bolt holes.
2. Wipe the liquid gasket application surface and the mating sur-
face with white gasoline (lighting and heating use) to remove
adhering moisture, grease and foreign materials.
3. Attach liquid gasket tube to the tube presser [SST: WS39930000
(—)].
Use Genuine RTV Silicone Sealant or equivalent. Refer to
GI-48, "
RECOMMENDED CHEMICAL PRODUCTS AND
SEALANTS" .
4. Apply liquid gasket without breaks to the specified location with
the specified dimensions.
If there is a groove for liquid gasket application, apply liquid
gasket to the groove.
As for bolt holes, normally apply liquid gasket inside the
holes. Occasionally, it should be applied outside the holes.
Make sure to read the text of this manual.
Within five minutes of liquid gasket application, install the mat-
ing component.
If liquid gasket protrudes, wipe it off immediately.
Do not retighten mounting bolts or nuts after the installation.
After 30 minutes or more have passed from the installation, fill
engine oil and engine coolant.
CAUTION:
If there are specific instructions in this manual, observe
them.
