APPENDIX

There are two types of areas available
for route guidance. In one type of area,
primarily around metropolitan centers,
detailed route guidance is available for
the entire area. In the other type of area,
all roads are displayed on the map but
route guidance is limited. The naviga-
tion route might lack precision because
the data (no right turns, one−way traf-
fic, etc.) is not complete. It is still pos-
sible to reach the destination by follow-
ing the arrow direction and distance as
shown on the bottom left of the screen.
The arrow points in the direction of the
destination. The distance shown is as
measured in a straight line from the cur-
rent vehicle position to the destination
area.
In order to provide you with as accurate
map information as possible, we are al-
ways gathering information such as on
road repairs and carrying out on −site in-
vestigations. However, the names of
roads, streets, facilities, and their locations
frequently change. In some places,
construction on roads may be in progress.
For that reason, information on some
areas in this system might be different from
the actual location.
The map database is normally updated
once a year. Contact your Lexus dealer for
information about the availability and pric-
ing of an update. When changing the map DVD
−ROM, we
recommend using your Lexus dealer.
To change the map DVD −ROM yourself,
follow these instructions carefully.
Do not use any tolls other than in −vehicle
tools.
For the storage location of the in −vehicle
tools, refer to the “Owner’s Manual” .
1. Set the “ENGINE START STOP”
switch in ACCESSORY mode.
2. Insert the 2 picks provided in the in−
vehicle tools into the holes on both
sides of the clock panel at a slight out-
ward angle until you hear a “click”.
