two or more cities), the name change will not
appear on the list. The street name closest
to the starting point will be displayed with a
mileage to the next turn.
These marks indicate the direction
which you should turn at an inter-
section.
INFORMATION
The current vehicle position mark
appears at the bottom of the screen
next to the name of the street you are
driving on. The mark does not move.
If you leave the guidance route, the
name of the street you are on is not
shown on the list next to the current
vehicle position mark.
If the road type you are on changes
between a highway, a main street or
a residential street (at an inter-
change or fork), it will appear on the
turn list.
If a long route has been selected, it
may take a long time to display the

Orientation of the Map Limitations of the Navigation System
39 You can change the orientation of the
map from North±up to Heading±up by
touching the direction symbol at the top
left of the screen.
North±up symbol
Regardless of the direction of vehicle travel,
North is always up.
Heading±up symbol
The direction of the vehicle travel is always
up. A red arrow indicates North.This navigation system calculates the
current vehicle position using satellite
signals, various vehicle signals, map
data, etc. However, an accurate position
may not be shown depending on the sat-
ellite condition, road configuration, ve-
hicle condition or other circumstances.
The Global Positioning System (GPS) devel-
oped and operated by the U.S. Department
of Defense provides an accurate current ve-
hicle position using 3 to 4 satellites. The
GPS system has a certain level of inaccura-
cy built in for security reasons. While the
navigation system will compensate for this
most of the time, occasional positioning er-
rors up to 300 feet can and should be ex-
pected. Generally, position errors will be cor-
rected within a few seconds.
When your vehicle is receiving signals from
the satellites, the ºGPSº mark appears at the
top left of the screen.
The GPS signal may be physically ob-
structed, leading to inaccurate vehicle posi-
tion on the map display. Tunnels, tall build-
ings, trucks, or even the placement of
objects on the instrument panel may obstruct
the GPS signals.
The installation of window tinting may also
obstruct the GPS signals. Most window tint-
ing contains some metallic content that will
interfere with the GPS signal reception.
Lexus recommends that window tinting
should not be used on vehicles equipped
with navigation systems.

Limitations of the Navigation System
41
(b) Inappropriate route guid-
ance may occur in the follow-
ing cases:
When turning at a wrong intersection off
the designated route guidance.
If you are heading for a destination with-
out passing through a set way point, auto-
matic rerouting may display a route re-
turning to the set way point.
When turning at an intersection, there is
no route guidance.
When passing through the intersection,
there is no route guidance.
During automatic rerouting, the route
guidance may not be available for the next
turn to the right or left.
It may take a long time to operate auto-
matic rerouting during high speed driving.
In automatic rerouting, a detour route may
be shown.
During automatic rerouting, the route may
not be changed.
The route in a U±turn may be shown or
announced.
A location may have multiple names and
the system will announce one or more.Some routes may not be searched.
If the route to your destination includes
gravel, unpaved roads or alleys, the route
guidance may not be shown.
Your destination point might be shown on
the opposite side of the street.
When a portion of the route has regula-
tions prohibiting the entry of the vehicle
that vary by time or season or other rea-
son.
The road and map data stored in your
navigation system may not be complete
or may not be the latest release.
When replacing the tire(s), contact your
dealer.
This navigation system uses the tire turning
data and is designed to work with factory±
specified tires for your Lexus. Installing tires
that are larger or smaller than the originally
equipped diameter may cause inaccurate
display of the vehicle's position. The tire
pressure also affects the diameter of the tires
so please make sure the tire pressure of all
four tires is correct.
