3-6.Tips for the navigation s ystem
The Global Positioning System (GPS)
developed and operated by the U.S.
Department of Defense provides an
accurate current vehicle position, nor-
mally using 4 or more satellites, and in
some case 3 satellites. The GPS sys-
tem has a certain level of inaccuracy.
While the navigation system will com-
pensate for this most of the time, occa-
sional positioning errors of up to 100 m
(100 yards) can and should be
expected. Generally, position errors
will be corrected within a few seconds.
The GPS signal may be physically
obstructed, leading to inaccurate vehi-
cle position on the map display. Tun-
nels, tall buildings, trucks, or even the
placement of objects on the instrument
panel may obstruct the GPS signals.
The GPS satellites may not send sig-
nals due to repairs or improvements
being made to them.
Even when the navigation system is
receiving clear GPS signals, the vehi-
cle position may not be shown accu-
rately or inappropriate route guidance
may occur in some cases.
 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 winding road.
• When driving on a slippery road such as
in sand, gravel, snow, etc.
• When driving on a long straight road.
• When motorway and surface streets run
in parallel.
• After moving by ferry or vehicle carrier.
• When a long route is searched during
high speed driving.
• After repeating a change of direction 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 tire chains installed.
• When the tires are worn.
• After replacing a tire or tires.
GPS (Global Positioning
System)
This navigation system calculates
the current vehicle position using
satellite signals, various vehicle sig-
nals, map data, etc. However, an
accurate position may not be shown
depending on satellite condition,
road configuration, vehicle condi-
tion or other circumstances.
Limitations of the navigation sys-
tem
NOTICE
●The installation of window tinting may
obstruct the GPS signals. Most win- dow tinting contains some metallic content that will interfere with GPS
signal reception of the antenna. We advise against the use of window tint-ing on vehicles equipped with naviga-
tion systems.

3-6. Tips for the navigation system
• When using tires that are smaller or
larger than the fact ory specifications.
• When the tire pressure in any of the four
tires is not correct.
 Inappropriate route guidance may
occur in the following cases:
• When turning at an intersection off the
designated route guidance.
• If you set more than one destination but
skip one of them, auto reroute will dis-
play a route returning to the destination
that was skipped.
• When turning at an intersection for
which there is no route guidance.
• When passing through an intersection
for which there is no route guidance.
• During auto reroute, 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
reroute 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.
• 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-
sons.
• The road and map data stored in the
navigation system may not be complete
or may not be the latest version.
●This navigation system uses tire turning data and is designed to work with fac-
tory-specified tires for the vehicle. Install- ing tires that are larger or smaller than the originally equipped diameter may cause
inaccurate display of the current vehicle position. The tire pressure also affects the diameter of the tires so make sure the
tires pressure of all four tires is correct.
