Example of Symptoms Judged Not MalfunctionNKS0049E
BASIC OPERATION
NOTE:
Locations stored in the Address Book and other memory functions may be lost if the vehicle's battery is disconnected or becomes dis-
charged. If this occurs, service the vehicle's battery as necessary and re-enter the information in the Address Book.
VEHICLE ICON
Symptom Possible cause Possible solution
No image is displayed.The brightness is at the lowest setting. Adjust the brightness of the display.
The display is turns off.
Push and hold to turn on the display.
No voice guidance is available.
The volume is too high or too low.The volume is not set correctly, or it is turned off. Adjust the volume of voice guidance.
Volume guidance is not provided for narrow streets
(roads displayed in gray).This is not a malfunction.
No map is displayed on the screen.The map DVD-ROM is not inserted, or it is inserted
upside down.Insert the map DVD-ROM correctly.
A screen other than map screen is displayed. Push “MAP”.
The screen is too dim.
The movement is slow.The temperature in the interior of the vehicle is low.Wait until the interior of the vehicle has
warmed up.
Some pixels in the display are
darker or brighter than others.This condition is an inherent characteristic of liquid
crystal displays.This is not a malfunction.
Some menu items cannot be
selected.Some menu items become unavailable while the
vehicle is driven.Park the vehicle in a safe location, and
then operate the navigation system.
Symptom Possible cause Possible solution
Names of roads and locations dif-
fer between Plan view and Bird-
view™.This is because the quantity of the displayed infor-
mation is reduced so that the screen does not
become too crowded. There is also a chance that
names of the roads or locations may be displayed
multiple times, and the names appearing on the
screen may be different because of a processing
procedure.This is not a malfunction.
The vehicle icon is not displayed in
the correct position.The vehicle was transported after the ignition switch
was turned off, for example, by a ferry or car trans-
porter.Drive the vehicle for a while on a road
where GPS can be received.
The position and direction of the vehicle may be
incorrect depending on the driving environments and
the levels of positioning accuracy of the navigation
system.This is not a malfunction. Drive the vehi-
cle for a while to automatically correct the
position and direction of the vehicle icon.
When the vehicle is travelling on a
new road, the vehicle icon is
located on another road nearby.Because the new road is not stored in the map data,
the system automatically places the vehicle ion on
the nearest road available. Updated road information will be included
in the next version of the map DVD-ROM.
The screen does not switch to the
night screen even after turning on
the headlights. The daytime screen was set the last time the head-
lights were turned on.Set the screen to the night screen mode
using when turning on the headlights.
The map does not scroll even
when the vehicle is moving.The current location map screen is not displayed. Push “MAP”.
The vehicle icon is not displayed. The current location map screen is not displayed. Push “MAP”.
The GPS indicator on the screen
remains gray.GPS signals cannot be received depending on the
vehicle location, such as in a parking garage, on a
road that has numerous tall buildings, etc.Drive on an open, straight road for a
while.
GPS signals cannot be received because objects
are placed on the rear parcel shelf.Remove the objects from the rear parcel
shelf.
A sufficient amount of GPS satellites are not avail-
able.Wait for the satellites to move locations
available for navigation system.

PlaceIn a parking lot When driving in a parking lot, or other loca-
tion where there are no roads on the map,
matching may place the vehicle mark on a
nearby road. When the vehicle returns to
the road, the vehicle mark may have devi-
ated from the correct location.
When driving in circle or turning the steer-
ing wheel repeatedly, direction errors accu-
mulate, and the vehicle mark may deviate
from the correct location.
If after traveling about 10 km (6
miles) the correct location has
not been restored, perform
location correction and, if nec-
essary, direction correction. Turntable
When the ignition switch is off, the naviga-
tion system cannot get the signal from the
gyroscope (angular speed sensor). There-
fore, the displayed direction may be wrong
and the correct road may not be easily
returned to after rotating the vehicle on a
turntable with the ignition off.
Slippery roads On snow, wet roads, gravel, or other roads
where tires may slip easily, accumulated
mileage errors may cause the vehicle mark
to deviate from the correct road.
Slopes When parking in sloped garages, when
traveling on banked roads, or in other
cases where the vehicle turns when tilted,
an error in the turning angle will occur, and
the vehicle mark may deviate from the
road.
Map dataRoad not displayed on the map screen
When driving on new roads or other roads
not displayed on the map screen, map
matching does not function correctly and
matches the location to a nearby road.
When the vehicle returns to a road which is
on the map, the vehicle mark may deviate
from the correct road.
Different road pattern
(Changed due to repair)
If the road pattern stored in the map data
and the actual road pattern are different,
map matching does not function correctly
and matches the location to a nearby road.
The vehicle mark may deviate from the
correct road.
VehicleUse of tire chains
When tire chains are used, the mileage is
not correctly detected, and the vehicle
mark may deviate from the correct road.Drive the vehicle for a while. If
the distance is still deviated,
adjust it by using the distance
adjustment function. (If the tire
chain is removed, recover the
original value.) Cause (condition) Driving condition Remarks (correction, etc.)

SYSTEM DESCRIPTIONPFP:00000
System FunctionsNKS004AB
Here is an example of functions. For details, refer to the owner's manual or navigation system owner's manual.
AUDIO
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
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.

More accurate traveling direction is detected because priorities are set for the signals from these two
devices according to the situation.
Map-Matching
Map-matching compares a current location detected by the method
in the “Location Detection Principle” with a road map data from Map
DVD-ROM stored in DVD-ROM drive.
NOTE:
The road map data is based on data stored in the map DVD-ROM.
The vehicle position may not be corrected under the following circumstances and after driving for a certain
time when GPS information is difficult to receive. In this case, the vehicle mark on the display must be cor-
rected manually.
In map-matching, alternative routes to reach the destination will
be shown and prioritized, after the road on which the vehicle is
currently driven has been judged and the vehicle mark has been
repositioned.
If there is an error in distance and/or direction, alternative routes
will be shown in different order of priority, and the incorrect road
can be avoided.
If two roads are running in parallel, they are of the same priority.
Therefore, the vehicle mark may appear on either of them alter-
nately, depending on maneuvering of the steering wheel and
configuration of the road.
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.
Type Advantage Disadvantage
Gyroscope
(angular velocity sensor)Can detect the vehicle's turning angle quite
accurately.Direction errors may accumulate when vehicle is
driven for long distances without stopping.
GPS antenna
(GPS information)Can detect the vehicle's travel direction
(North/South/East/West).Correct direction cannot be detected when vehi-
cle speed is low.
