1. DRIVING TEST 1
1. Scroll the map screen to display the area to make correction. Press “ENTER” and select “CURRENT LOCATION CORRECTION”.
2. Correct direction of the vehicle mark.
3. Perform the distance correction of the CONFIRMATION/ADJUSTMENT mode. Note: Normally, adjustment is not necessary because this system has automatic distance correction func-
tion. However, when a tire chain is fitted, adjustment in accordance with the tire diameter ratio must be
made.
4. Are symptoms malfunctioning to the AV- 1 7 1 , "
Example of Symptoms Judged Not Malfunction" present
after driving the vehicle?
YES or NO
YES >> Limit of the location detection capacity of the navigation system.
NO >> GO TO 2.
2. DRIVING TEST 2
Did any malfunction occur when the proper test in the following test patterns is performed?
Test pattern
Driving test finds the difference between the symptoms monitored with and without each sensor.
–Test pattern 1: Test method with no GPS location correction
Disconnect GPS antenna connector (GT5) connected to the NAVI control unit. Accurately adjust the cur-
rent location and the direction, and then drive the vehicle.
–Test pattern 2: Test method with no map-matching
Accurately adjust the current location and the direction. Eject the map DVD-ROM from the NAVI control
unit with ignition switch turned to OFF, and then drive the vehicle. After driving, insert the map DVD-ROM
back in the unit, display the track of the vehicle on the map screen and compare it with the actual road
configuration.
Sample tests
– matching or by GPS>
Perform test pattern 1.
–;
Perform test pattern 1 and 2.
Compare the track of the vehicle on the map screen and the actual road configuration. For fairly accurate
tracking, plotting shall be made every several hundred meters.
–;
Perform test pattern 1 and 2.
Drive on a road of which distance is accurately known (by utilizing distance posts on a highway). Calculate
the rate of change (increased/decreased) of the distance by comparing with the actual distance.
Correction = A/B
A: Distance shown on the screen
B: Actual distance
YES or NO
YES >>If adjustment is insufficient, perform adjustment again.
If any error is found in the map, please let us know.
Replace NAVI control unit.
NO >> Limit of the location detection capacity of the navigation system.

No image is shown. Display brightness adjustment is set fully to DARK side. Adjust the display brightness.
No guide sound is heard.
Audio guide volume is too low or
too high. Volume control is set to OFF, MIN or MAX. Adjust the audio guide volume.
Audio guidance is not available while the vehicle
is driving on a dark pink route. System is not malfunction.
Screen is too dark.
Motion of the image is too slow. Temperature inside the vehicle is low. Wait until the temperature inside the vehicle
reaches the proper temperature.
Small black or bright spots appear
on the screen. Symptom peculiar to a liquid crystal display. System is not malfunction.
Symptom Cause Remedy
Map screen and BIRDVIEW™
Name of the place vary with the
screen. Some thinning of the character data is done to
prevent the display becoming to complex. In
some cases and in some locations, the display
contents may differ.
The same place name, street name, etc. may not
be displayed every time on account of the data
processing. System is not malfunction.
Vehicle mark is not positioned cor-
rectly. Vehicle is transferred by ferry or by towing after its
ignition switch is turned to OFF. Drive the vehicle for a while in the GPS sat-
ellite signal receiving condition.
Screen will not switch to nighttime
mode after the lighting switch is
turned ON. The daytime screen is selected by the “SWITCH
SCREENS” when the last time the screen dim-
ming setting is done.
Switching between daytime/nighttime screens
may be inhibited by the automatic illumination
adjustment function. Perform screen dimming and select the
nighttime screen by “SWITCH SCREENS”.
Map screen will not scroll in accor-
dance with the vehicle travel. Current location is not displayed. Press “MAP” button to display the current
location.
Vehicle mark will not be shown. Current location is not displayed. Press “MAP” button to display the current location.
Accuracy indicator (GPS satellite
mark) on the map screen stays
gray. GPS satellite signal is intercepted because the
vehicle is in or behind a building. Move the vehicle out to an open space.
GPS satellite signal cannot be received because
an obstacle is placed on top of the display. Do not place anything in the center on top of
the display.
GPS satellites are located badly. Wait until the location becomes better.
Vehicle location accuracy is low. Accuracy indicator (GPS satellite mark) on the map screen stays gray. Current location is not determined.
Vehicle speed setting by the vehicle speed pulse
has been deviated (advanced or retarded) from
the actual vehicle speed because tire chain is fit-
ted or the system has been used on another vehi-
cle. Drive the vehicle for a while [for approx. 30
minutes at approx. 30 km/h (19 MPH)] and
the deviation will be automatically adjusted.
If advancement or retard still occur, perform
the distance adjustment by CONFIRMA-
TION/ADJUSTMENT mode of diagnosis
function.
Map data has error or omission. (Vehicle mark is
always deviated to the same position.) As a rule, an updated map DVD-ROM will be
released once a year.

Symptom Cause Remedy
Destination cannot be set. Destination to be set is on an expressway. Set the destination on an ordinary road.
Passing point is not searched
when re-searching the route. The vehicle has already passed the passing point,
or the system judged so. To include the passing points that have been
passed into the route again, set the route
again.
Route information will not be dis-
played. Route searching has not been done. Set the destination and perform route
searching.
Vehicle mark is not on the recommended route. Drive on the recommended route.
Route guide is turned OFF. Turn route guide ON.
Route information is not available on the dark pink
route. System is not malfunction.
After the route searching, no guide
sign will appear as the vehicle
goes near the entrance/exit to the
toll road. Vehicle mark is not on the recommended route.
(On the display, only guide signs related to the
recommended route will be shown.) Drive on the recommended route.
Automatic route searching is not
possible. Vehicle is driving on a highway (gray route), or no
recommended route is available. Drive on a road to be searched. Or re–
search the route manually. In this case, how-
ever, the whole route will be searched.
Performed automatic detour
search (or detour search). How-
ever, the result is the same as that
of the previous search. Performed search with every condition consid-
ered. However, the result is the same as that of
the previous search. System is not malfunction.
Passing points cannot be set. More than five passing points were set. Passing points can be set up to five. To stop at more than five points, perform sharing in
several steps.
When setting the route, the start-
ing point cannot be selected. The current vehicle location is always set as the
starting point of a route. System is not malfunction.
Some menu items cannot be
selected. The vehicle is being driven. Stop the vehicle at a safe place and then
operate the system.
Symptom Cause Remedy
Voice guide will not operate. Note: Voice guide is only available at intersections that satisfy certain conditions . Therefore, guid-
ance may not be given even when the route on the
map changes direction. System is not malfunction.
The vehicle is not on the recommended route. Return to the recommended route or re- search the route.
Voice guide is turned OFF. Turn voice guide ON.
Route guide is turned OFF. Turn route guide ON.
Voice guide does not match the
actual road pattern. Voice guide may vary with the direction to which
the vehicle is turn and the connection of the road
to other roads. Drive in conformity to the actual traffic rules.
Symptom Cause Remedy
No route is shown. No road to be searched is found around the des- tination. Find wider road (orange road or wider)
nearby and reset the destination and passing
points onto it. Take care of the traveling
direction when there are separate up and
down roads.
Starting point and the destination are too close. Set the destination at more distant point.
Conditional traffic regulation (day of the week/
time of the day) is set at the area around the cur-
rent location or the destination. Turn the time-regulating search conditions
OFF. Turn “Avoid regulation time” in the
search conditions OFF.

NOTE:
Except for the ordinance-designated cities and the prefectural capitals (Malfunctioning areas may be changed in the updated map disc.)
Indicated route is intermittent. In some areas, highways (gray routes) are not
used for the search
(Note) Therefore, the route to
the current location or the passing points may be
intermittent. System is not malfunction.
When the vehicle has passed the
recommended route, it is deleted
from the screen. A recommended route is controlled by each sec-
tion. When the vehicle has passed the passing
point 1, then the map data from the starting point
up to the passing point 1 will be deleted. (The
data may remain undeleted in some area.) System is not malfunction.
Detouring route is recommended. In some areas, highways (gray routes) are not used for the search.
(Note) Therefore, detour
route may be recommended. Set the route closer to the basic route (gray
route).
A detour route may be shown when some traffic
regulation (one-way traffic, etc.) is set at the area
around the starting point or the destination. Slightly move the starting point or the desti-
nation, or set the passing point on the route
of your choice.
In the area where highways (gray routes) are
used for the search, left turn has priority around
the current location and the destination (passing
points). For this reason, the recommended route
may be detouring. System is not malfunction.
Landmarks on the map do not
match the actual ones. This can be happen due to omission or error in
the map data. As a rule, an updated map DVD-ROM will be
released once a year. Wait until the latest
map has become available.
Recommended route is far from
the starting point, passing points,
and destination. Starting point, passing points, and destination of
the route guide were set far from the desired
points because route searching data around
these area were not stored. Reset the destination onto the road nearby. If
this road is one of the highways (gray
routes), an ordinary road nearby may be dis-
played as the recommended route.

NAVIGATION SYSTEM
Revision: 2005 July 2005 FX
Place In 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 10km
(6miles) the correct location
has not been restored, perform
location correction and, if nec-
essary, direction correction.
Turn ta ble
When the ignition switch is OFF, the navi-
gation system cannot get the signal from
the gyroscope (angular speed sensor).
Therefore, the displayed direction may be
wrong and the correct road may not be
easily returned to after rotating the vehicle
on a turn table 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 data Road 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.
Vehicle Use 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.)

CURRENT LOCATION MARK SHOWS A POSITION WHICH IS COMPLETELY WRONG
In the following cases, the current-location mark may appear on completely different position in the map
depending on the GPS satellite signal receiving conditions. In this case, perform location correction and direc-
tion correction.
When location correction has not been done
–If the receiving conditions of the GPS satellite signal is poor, if the current-location mark becomes out of
place, it may move to a completely different location and not come back if location correction is not done.
The position will be corrected if the GPS signal can be received.
When the vehicle has traveled by ferry, or when the vehicle has been being towed
–Because calculation of the current location cannot be done when traveling with the ignition OFF, for exam-
ple when traveling by ferry or when being towed, the location before travel is displayed. If the precise loca-
tion can be detected with GPS, the location will be corrected.
CURRENT-LOCATION MARK JUMPS
In the following cases, the current-location mark may appear to jump as a result of automatic correction of the
current location.
When map matching has been done
–If the current location and the current-location mark are different when map matching is done, the current-
location mark may seem to jump. At this time, the location may be “corrected” to the wrong road or to a
location which is not on a road.
When GPS location correction has been done
–If the current location and the current-location mark are different when the location is corrected using GPS
measurements, the current-location mark may seem to jump. At this time, the location may be “corrected”
to a location which is not on a road.
Precautions
for driving Just after the engine is started
If the vehicle is driven off just after the
engine is started when the gyroscope
(angular speed sensor) correction is not
completed, the vehicle can lose its direc-
tion and may have deviated from the cor-
rect location. Wait for a short while before
driving after starting the engine.
Continuous driving without stopping When driving long distances without stop- ping, direction errors may accumulate, and
the current-location mark may deviate from
the correct road. Stop and adjust the orientation.
Abusive driving Spinning the wheels or engaging in other kinds of abusive driving may result in the
system being unable perform correct
detection, and may cause the vehicle mark
to deviate from the correct road. If after traveling about 10 km (6
miles) the correct location has
not been restored, perform
location correction and, if nec-
essary, direction correction.
How to cor-
rect location Position correction accuracy
If the accuracy of location settings is poor,
accuracy may be reduced when the correct
road cannot be found, particularly in places
where there are many roads. Enter in the road displayed on
the screen with an accuracy of
approx. 1mm.
Caution: Whenever possible,
use detailed map for the cor-
rection.
Direction when location is corrected
If the accuracy of location settings during
correction is poor, accuracy may be
reduced afterwards. Perform direction correction.
