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 posi-
tion even after the vehicle
has been driven approxi-
mately 10 km (6 miles), per-
form ªAdjust Current Loca-
tionº MODE (EL-298). If
necessary, perform ªSpeed
Calibrationº (EL-290). 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 pos-
sible. The position marker may indi-
cate 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 posi-
tion even after the vehicle
has been driven approxi-
mately 10 km (6 miles), per-
form ªSpeed Calibrationº (EL-
290). After removing the tire
chains, sensing accuracy
may recover by itself.
