Possible cause Drive condition Service procedure
AreaSlippery road surfaceOn wet, icy, or gravel road where
frequent wheel slippage occurs, dis-
tance calculations may be errone-
ous. The position marker may show
the vehicle to be in inaccurate posi-
tion.
If the position marker does not
move to the correct position
even after the vehicle has been
driven approximately 10 km (6
miles), perform ªADJUST CUR-
RENT LOCATIONº (EL-411). If
necessary, perform ªSPEED
CALIBRATIONº (EL-409). Slanted areaHilly areas where the road has
banked curves. When the vehicle
enters these banked curves, there
may be an error in steering angle
measurement. The position marker
may show the vehicle to be in inac-
curate position.
Map
dataMap display for a given road does not appear.
SEL699V
When the vehicle is driven on a
newly constructed road that does
not appear on the existing map.
Map marking and calibration are not
possible. The position marker may
indicate inaccurate position in close
proximity to the actual position.
Subsequently, when the vehicle is
driven on a road which is available
as map data, the position marker
may still indicate an inaccurate posi-
tion.
The vehicle is driven on a road whose course
has been altered (usually to improve the road or
to eliminate some hazard).
SEL700V
When the map data shown on the
display and the actual conditions are
different. Map matching will not be
possible. The position marker may
indicate inaccurate position in close
proximity to the actual position. If
the vehicle is driven on the indicated
road, further errors may occur.
Vehicle Use of tire chains (Stormy weather)Tire chains will affect distance sens-
ing. The position marker may indi-
cate inaccurate position.If the position marker does not
move to the correct position
even after the vehicle has been
driven approximately 10 km (6
miles), perform ªSPEED CALI-
BRATIONº (EL-409). After
removing the tire chains, sens-
ing accuracy may recover by
itself.

Possible cause:
Ð: Vehicle running ---: IndicationDrive condition Service procedure
Road
shapesY-intersection
SEL703V
In Y-intersections with a very
gradual change in course, a direc-
tional sensing may be inaccurate.
This may result in the position
marker giving the wrong road indica-
tion.
If the position marker does not
move to the correct position
even after the vehicle has been
driven approximately 10 km (6
miles), perform ªStore placeº. If
required, also perform
ªADJUST CURRENT LOCA-
TIONº (EL-411). Spiral road
SEL704V
On loop bridges and similar struc-
tures which result in a large and
continuous turn, turning angle may
be sensed inaccurately. As a result,
the position marker may separate
from the route on the map.
Straight road
SEL705V
In long distance driving on a straight
road or road with very gradual
curves, map marking inaccuracies
may occur. In such cases, the posi-
tion marker may stray from the route
being traveled during subsequent
turns due to inaccurate distance cal-
culation.
Winding road
SEL706V
Directional sensing precision errors
may occur when traveling on wind-
ing roads. During map matching, the
position marker may stray to an
adjacent road having a similar
shape. Subsequent position marker
error may occur.
Grid-like road shape
SEL707V
Directional sensing and distance
sensing, precision errors may occur
because of many roads having a
similar shape in the immediate area.
During map matching, the position
marker may stray to an adjacent
road having a similar shape. Subse-
quent position marker error may
occur.
Parallel roads
SEL708V
When driving on a parallel road,
map matching errors may occur.
Subsequent position marker error
may also occur.

NAVIGATION SYSTEM
This Condition is Not Abnormal (Cont'd)
EL-427

GPS signal reception conditions are good. However, the position mark does not return to its proper
position.
Ihe system senses the vehicle location with an error of approximately 100 m (328 ft). Due to the limitation
of precision, the position marker may be inaccurate even if the GPS signal reception condition is good.
IThe navigation system uses GPS data to determine vehicle location. GPS data is compared with other
locational sensing data during the map matching process. The system decides which data is more pre-
cise and uses that data.
IWhen the vehicle is stationary, GPS data cannot be used to make system corrections.
Area designations on the map display and the BIRDVIEWTdisplay differ.
To prevent the display from becoming congested, alphanumeric information is abridged.
[No problem]
Correct position of your vehicle is not displayed.
Vehicle position changed after ignition key was turned to the OFF position (Vehicle is transported on car ferry,
car train, or by some other means).
[Operate vehicle for short time under GPS receiving conditions.]
The display does not change to night-time mode even though the light switch has been turned ON.
Lights have been turned on. In ªDISPLAY CHANGEº mode, night-time mode on display has been switched to
day-time mode and still is.
[Turn lights on again. Set the display to night-time mode. Refer to EL-412.]
Map does not scroll even though the position of your vehicle is changed.
Present area does not appear on the display.
[Press the ªMAPº switch.]
Vehicle position marker does not appear.
Present area does not appear on the display.
[Press the ªMAPº switch.]
The map surface precision display (GPS satellite marker) still remains gray.
Vehicle is parked inside a building or in the shadow of a large building. This intercepts the GPS signal.
[Move the vehicle to a more open position.]
GPS signal is not received because objects are placed on the rear parcel shelf.
[Remove objects from the rear parcel shelf.]
GPS satellite position is bad.
[Wait until GPS satellite position improves.]
Vehicle position precision is bad.
The map surface precision display (GPS satellite marker) still remains gray.
[Refer to ªThe map surface precision display (GPS satellite marker) still remains grayº item (Symptoms)]
Vehicle speed and elapsed distance is calculated from the vehicle speed pulse. This pulse is dependent upon
tire size. If tire chains are used on the vehicle, accuracy will be affected (pulse rate will be too fast or too slow).
The same is true if the system installed to your vehicle is removed and installed on another vehicle.
[Drive the vehicle at a speed higher than 30 km/h (19 MPH) for approximately 30 minutes. Automatic read-
justment should occur. If it does not (remains too fast or too slow), distance calibration is required. Or, drive
the vehicle for a short distance. Perform ªSPEED CALIBRATIONº (EL-409). After removing the tire chains,
sensing accuracy may recover by itself.]
Bad map data or system defect (same error consistently occurs in the same area)
ROUTE SEARCH/ROUTE GUIDENBEL0235S03IIf the present location or the destination location is displayed in the avoid area, it is not possible to search
routes.
IIf the avoid area is set to wide range area, it may not be possible to find appropriate routes or search for
alternate routes.
IThe automatic re-route calculates a return to the original route. Because of this, it may not be possible to
search appropriate new routes. If you deviate from the original route and wish to select an appropriate new
route, touch ªRoute Calculationº.
IThe automatic re-route function may sometimes require considerable time.
IDisplayed route number and directional information at a highway junction may differ from the information
posted on the actual road signs.
IDisplayed street name information at a highway exit may differ from the information posted on the actual
road signs.
IStreet name information displayed on the enlarged intersection map may differ from the information posted
on the actual road signs.

even if the selected route is a major one,
appropriate route search data may not be
available.
LOCATION OF CAR MARKERNBEL0235S04IIf the vehicle has been parked in a multi-level parking facility or underground parking facility, the car marker
position may be inaccurate immediately after exiting the parking facility.
IThe GPS accuracy is within±100 m (300 ft). Even when receiving conditions are excellent, further posi-
tional correction may not occur.
STREET INDICATIONNBEL0235S05IStreet names displayed on the map may differ from the actual street names.
