window Lexus IS250 2012 Navigation Manual

APPENDIX
372
This navigation system calculates the
current vehicle position using satellite
signals, various vehicle signals, map
data, etc. However, the accurate posi-
tion may not be shown depending on
the satellite condition, road configura-
tion, vehicle condition or other circum-
stances.
The Global Positioning System (GPS) de-
veloped and operated by the U.S. Depart-
ment of Defense provides an accurate cur-
rent vehicle position, normally using 4 or
more satellites, and in some case 3 satel-
lites. The GPS system has a certain level
of inaccuracy. While the navigation sys-
tem will compensate for this most of the
time, occasional positioning errors of up to
300 feet (100 m) can and should be expec-
ted. Generally, position errors will be cor-
rected within a few seconds.
When your vehicle is receiving signals
from the satellites, the “GPS” mark ap-
pears at the top left of the screen.
The GPS signal may be physically ob-
structed, leading to inaccurate vehicle
position on the map display. Tunnels, tall
buildings, trucks, or even the placement of
objects on the instrument panel may ob-
struct the GPS signals.
The GPS satellites may not send signals
due to repairs or improvements being
made to them.
Even when the navigation system is re-
ceiving clear GPS signals, the vehicle
position may not be shown accurately or
inappropriate route guidance may occur in
some cases.
NOTICE
The installation of window tinting
may obstruct the GPS signals. Most
window tinting contains some metal-
lic content that will interfere with GPS
signal reception of the antenna in the
instrument panel. We advise against
the use of window tinting on vehicles
equipped with navigation systems.
