Inputting letters and numbers
2The navigation system operates by
switches on the screen and on the bezel.
When you touch a switch, a beep sounds.
When using the switches on the touch
screen, please use only light pressure
with your finger to protect the screen
from damage. Do not use objects other
than your finger to touch the screen.
UN005
To type in an address etc., directly touch al-
phabet keys on the screen. If you touch a
wrong letter, delete it using the
switch.
Touching the
switch erases one letter.Touching the
ºListº switch will change the
screen to a display of the database items that
match the name or address that you have
entered on the screen. The number of
matching items is shown to the right side of
the screen. If the matching item is more than
9,999, the system displays º
º on the
screen.
To input numerals, touch the
º0±9º switch
and the display will change the screen to
number input display.
UN006
Touching the ºA±Zº switch changes the
screen back to the previous name input dis-
play.
UN007
When a list is displayed, you can scroll or
page through the list by using the appropri-
ate switch.
To shift to the next or previous
page.
To scroll up or down one item at
a time.
This expresses a displayed
screen position.

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
40The GPS satellites may not send signals due
to repairs or improvements being made to
them.
Even when the navigation system is receiv-
ing good GPS signals, the vehicle position
may not be shown accurately or inappropri-
ate route guidance may occur in some
cases.
(a) Accurate current vehicle
position may not be shown in
the following cases:
When driving on a small angled Y±
shaped road.
When driving on a spiral road.
When driving on a slippery road such as
in sand, gravel, snow, etc.
When driving on a long straight road.
When freeway and surface streets run in
parallel.
After moving by ferry or vehicle carrier.
When a long route is searched during high
speed driving.
When driving without setting the current
position calibration correctly.
After repeating a change of directions by
going forward and backward, or turning
on a turntable in the parking lot.
When leaving a covered parking lot or
parking garage.
When a roof carrier is installed.
When driving with the tire chains installed.When the tires are worn.
After replacing a tire or tires.
When using tires that are smaller or larger
than the factory specifications.
When the tire pressure in any of the four
tires is not correct.
INFORMATION
If your vehicle cannot receive GPS sig-
nals, you can correct the current posi-
tion manually. For the information on
setting the current position calibration,
see page 61.

Limitations of the Navigation System

(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.
