NORMAL OPERATING CONDITION

Route Search

NOTE:
Except for the ordinance-designated cities. (Malfunctioning areas may be changed in the updated map disc.)

Examples of Current-Location Mark Displacement

Symptom

Cause

Remedy

Voice guide will not operate.

Note: Voice guide is only available at intersections
that satisfy certain conditions (indicated by z on
the map). Therefore, guidance may not be given
even when the route on the map changes direction.

System is not malfunctioning.

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 ac-
tual 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) near-
by and reset the destination and passing
points onto it. Take care of the traveling direc-
tion 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.

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 malfunctioning.

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 malfunctioning.

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 destina-
tion, 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 malfunctioning.

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 displayed as
the recommended route.

Vehicle's travel amount is calculated by reading its travel distance and turning angle. Therefore, if the vehicle

is driven in the following manner, an error will occur in the vehicle's current location display. If correct location

has not been restored after driving the vehicle for a while, perform location correction.

Driving condition

Remarks (correction, etc.)

Road config-
uration

Y–intersections

At a Y intersection or similar gradual divi-
sion of roads, an error in the direction of
travel deduced by the sensor may result in
the current-location mark appearing on the
wrong road.

If after travelling about 10 km (6
miles) the correct location has
not been restored, perform lo-
cation correction and, if neces-
sary, direction correction.

Spiral roads

When driving on a large, continuous spiral
road (such as loop bridge), turning angle
error is accumulated and the vehicle mark
may deviate from the correct location.

Straight roads

When driving on a long, straight road and
slow curve without stopping, map-matching
does not work effectively enough and dis-
tance errors may accumulate. As a result,
the vehicle mark may deviate from the cor-
rect location when the vehicle is turned at a
corner.

Zigzag roads

When driving on a zigzag road, the map
may be matched to other roads in the simi-
lar direction nearby at every turn, and the
vehicle mark may deviate from the correct
location.

Roads laid out in a grid pattern

When driving where roads are laid out in a
grid pattern, or where many roads are run-
ning in the similar direction nearby, the map
may be matched to them by mistake and
the vehicle mark may deviate from the cor-
rect location.

Parallel roads

When two roads are running in parallel
(such as highway and sideway), the map
may be matched to the other road by mis-
take and the vehicle mark may deviate from
the correct location.

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 travelling about 10 km (6
miles) the correct location has
not been restored, perform lo-
cation correction and, if neces-
sary, direction correction.

Turntable

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 eas-
ily 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
travelling on banked roads, or in other cas-
es 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 cor-
rect 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 still deviates, ad-
just it by using the distance ad-
justment function. (If the tire
chain is removed, recover the
original value.)
