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.

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

map other than your current vehicle position,
you can bring the desired point to the center
of the screen by using the scroll feature.

direction until you lift your finger.If you touch switches like
ºMarkº, ºPOIº,
etc., the screen does not scroll and the re-
spective function operates.

nearest to the point you touched is set
as the destination. At this time, if the
nearest road is over 3 miles from des-
tination point, the system may not be
able to calculate a guidance route.

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.
