NORMAL OPERATING CONDITION

EXAMPLES OF CURRENT LOCATION MARK DISPLACEMENT

It calculates vehicle travel by reading travel distance and turn angle. Therefore, a mistake will occur in the cur-
rent location display if the vehicle is driven in the following manner. Perform location correction if correct loca-
tion has not been restored after driving the vehicle normally.

Rear view monitor image is not
clear

Front glass of camera lens is dirty.

Dip a soft cloth into water and wipe the glass
softly.

There are raindrops, snow, etc.

Wipe it with a soft cloth softly.

The sunlight or the headlight of following vehicle is
shining directly to the camera lens.

It returns to the original condition if the light
applied to the lens disappears.

Road pat-
tern

Y-intersections

At a Y intersection or similar gradual
division of roads, errors in the direc-
tion of travel deduced by the sensor
may result in the current location
mark appearing on the wrong road.

Perform location correction and, if
necessary, direction correction if the
correct location has not been re-
stored after traveling about 10 km/h
(6 MPH).

Spiral roads

Turning angle errors accumulate
and vehicle mark may deviate from
the correct location when driving on
a large, continuous spiral road (such
as loop bridge).

Straight roads

Map-matching does not work effec-
tively enough and distance errors
may accumulate when driving on a
long, straight, slowly curving road
without stopping. As a result, the ve-
hicle mark may deviate from the cor-
rect location when the vehicle turns
at a corner.

Switchback turns

The map may be matched to other
roads in a similar direction nearby at
every turn, and the vehicle mark
may deviate from the correct loca-
tion when driving on a zigzag road.

Grid pattern roads

The map may be matched to them
by mistake and the vehicle mark
may deviate from the correct loca-
tion when driving in a location where
roads are laid out in a grid pattern,
where many roads are running in the
similar direction nearby.

Parallel roads

The map may be matched to the oth-
er road by mistake and the vehicle
mark may deviate from the correct
location when two roads are running
in parallel (such as highway and
sideway).

Place

In a parking lot

Matching may place the vehicle
mark on a nearby road when driving
in a parking lot, or other locations
where there are no roads on the
map. The vehicle mark may have
deviated from the correct location
when the vehicle returns to the road.
Direction errors accumulate, and the
vehicle mark may deviate from the
correct location when driving in cir-
cle or turning the steering wheel re-
peatedly.

Perform location correction and, if
necessary, direction correction if the
correct location has not been re-
stored after traveling about 10 km/h
(6 MPH).

Turntable

The navigation system cannot re-
ceive the signal from the gyroscope
(angular speed sensor) when the ig-
nition switch is OFF. Therefore, the
displayed direction may be incorrect
and the correct road may not be eas-
ily returned to after rotating the vehi-
cle on a turntable with the ignition
OFF.

Slippery roads

On snow, wet roads, gravel, or other
roads where tires may slip easily, ac-
cumulated mileage errors may
cause the vehicle mark to deviate
from the correct road.

Slopes

An error in the turning angle will oc-
cur, and the vehicle mark may devi-
ate from the road when parking in
sloped garages, when traveling on
banked roads, or in other cases
where the vehicle turns when tilted.

Map data

Roads not displayed on the map screen

Map matching does not function cor-
rectly and matches the location to a
nearby road when driving on new
roads or other roads not displayed
on the map screen. The vehicle
mark may deviate from the correct
road when the vehicle returns to a
road which is on the map.

Different road pattern
(Changed due to repair)

Map matching does not function cor-
rectly and matches the location to a
nearby road if the road pattern
stored in the map data and the actu-
al road pattern are different. The ve-
hicle mark may deviate from the
correct road.

THE CURRENT POSITION MARK SHOWS A POSITION THAT IS COMPLETELY INCORRECT.

In the following cases, the current location mark may be displayed in a completely incorrect location. If so, per-
form position/direction correction.
• When location correction has not been done
- It may shift to a completely unexpected location and not return unless location correction is performed if

GPS satellite reception is poor and the current location mark slips out of place. The position will be corrected
if a GPS signal can be received.

• When vehicle is traveled by ferry, or when vehicle is towed.
- Because calculation of the current location cannot be done when traveling with the ignition OFF, for example

when traveling by ferry or when being towed, the location before travel is displayed. The location will be cor-
rected if the precise location can be detected with GPS.

Vehicle

Use of tire chains

The vehicle mark may deviate from
the correct road.

Drive the vehicle for a while. Adjust
it with the distance adjustment func-
tion if distance still deviates. (Re-
cover the original value if tire chains
are removed.)

Use of tires other than the specified size

Replace all tires with the specified
size tire.

Malfunctioning air pressure of tire

Adjust all tires to the specified air
pressure.

Replace tire

Drive the vehicle for a while. It ad-
justs with the distance adjustment
function if the distance is still not in
the correct location.

Driving man-
ner

Just after the engine is started

The vehicle can be shown in the in-
correct direction and may deviate
from the correct location if vehicle is
driven off just after the engine is
started when gyroscope (angular
speed sensor) correction is not com-
pleted.

Wait for a short while before driving
after starting the engine.

Continuous driving without stopping

Direction errors may accumulate,
and the current location mark may
deviate from the correct road when
driving long distances without stop-
ping.

Stop and adjust 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.

Perform location correction and, if
necessary, direction correction if af-
ter traveling about 10 km/h (6 MPH)
the correct location has not been re-
stored.

Position cor-
rection
method

Position correction accuracy

Accuracy may be reduced when cor-
rect road cannot be found, particu-
larly in places where there are many
roads if accuracy of location settings
is poor.

From the roads displayed on the
screen, input a position within an
accuracy of 1mm (0.04 in).

CAUTION:

When correcting, use the most
detailed map possible.

Direction when location is corrected

Accuracy may be reduced after-
wards if accuracy of location set-
tings during correction is poor.

Perform direction correction.
