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.
