SECTION I

Inputting Letters and Numbers
2The navigation system operates by
switches on the screen and the buttons
located on the front face around the
screen. When you touch a switch or push
a button, 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.
1UE001
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
ªListº 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
ªº on the
screen.
To input numerals, touch the
ª0±9º switch
and the display will change the screen to
number input display.
1UE002
Touching the ªA±Zº switch changes the
screen back to the previous name input dis-
play.
1UE003
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.

Destination Input by Emergency
20By touching the
ªEmergencyº switch
on the Destination screen, the display
changes to a screen to select dealers,
hospitals or police stations. During driv-
ing, only nearby police stations, hospi-
tals or dealers are shown. The current
position is shown with an address, the
latitude and the longitude at the top of the
screen.
1UE027
When you touch your desired emergency
category, the selected emergency category
list is displayed.
1UE028
The distance from your current position up to
the destination is displayed on the right of the
name.
You can see the names of the emergency
destinations in alphabetical order by touch-
ing the
ªName Sortº switch on the
screen.
Touch the
of your desired item. The
screen changes and displays the map
location of the selected destination and
the route preference. (See
ª(a) Entering
Destinationº on page 25.)
Touch the
ªInfo.º switch on the screen to
display the selected emergency destination
name, address and telephone number.
INFORMATION
The navigation system does not guide
in areas where route guidance is un-
available. (See page 56.)

Limitations of the Navigation System
53 This navigation system calculates the
current vehicle position using satellite
signals, various vehicle signals, map
data, etc. However, the 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 inaccuracy built
in for security reasons. While the navigation
system will compensate for this most of the
time, occasional positioning errors up to 300
feet can and should be expected. Generally,
position errors will be corrected within a few
seconds.
1UE087a
When your vehicle is receiving signals from
the satellites, the ªGPSº 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. We
recommend not to use the window tinting on
vehicles equipped with navigation systems.The 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.

Limitations of the Navigation System
54
(a) Accurate current vehicle posi-
tion may not be shown in the fol-
lowing 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 80.
(b) Inappropriate route guidance
may occur in the following cases:
When turning at a wrong intersection off
the designated route guidance
If you set more than one destination, auto
reroute will display a route returning to the
destination on the previous route when
you try to skip any of the destinations.
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 re-
route during high speed driving. In auto
reroute, a detour route may be shown.
After auto reroute, the route may not be
changed.
An unnecessary U±turn may be shown or
announced.
A location may have multiple names and
the system will announce one or more.

Limitations of the Navigation System
55 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), do the calibra-
tion. See page 80 for detailed information.

Map Database Information and Updates

based on NAVTECH maps, GDT maps
and infoUSA POIs.

There are two types of areas available for
route guidance. (See the following
pages.) 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 guid-
ance is limited. The navigation route
might lack precision because the data (no
right turns, one±way traffic, etc.) is not
complete. It is still possible to reach the
destination by following the arrow direc-
tion 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 current vehicle position to the
destination area.

1UE088a
In order to provide you with accurate map in-
formation as much as possible, we are al-
ways gathering information such as road re-
pairs and doing site investigation. However,
the names of roads, streets, facilities, and
their locations are often changed. In some
places, construction on roads may be in pro-
gress. 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 infor-
mation about the availability and pricing of an
update.
