Example of Symptoms Judged Not MalfunctionEKS00BL3
BASIC OPERATION
VEHICLE MARK
Symptom Cause Remedy
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 malfunctioning.
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 (dis-
play unit).System is not malfunction.
Symptom Cause Remedy
Map screen and BIRDVIEW™
Name of the place varies 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 malfunctioning.
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 screen may
be inhibited by the automatic illumination adjust-
ment 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 instrument
panel.Do not place anything in the center on top of
the display.
GPS satellites are not visible from current loca-
tion.Wait until GPS satellites are visible by mov-
ing the vehicle.
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.

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 travelling 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 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 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
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.
Vehicle Use of tire chainsWhen 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,
adjust it by using the distance
adjustment function. (If the tire
chain is removed, recover the
original value.) Cause (condition) –: While driving ooo: Display Driving condition Remarks (correction, etc.)
