6. TIPS FOR THE NAVIGATION SYSTEM
1. GPS (GLOBAL POSITIONING SYSTEM)
The Global Positioning System (GPS) de-
veloped and operated by the U.S. Depart-
ment of Defense provides an accurate
current position, normally using 4 or more
satellites, and in some case 3 satellites. The
GPS system has a certain level of inaccura-
cy. While the navigation system compen-
sates for this most of the time, occasional
positioning errors of up to 300 ft. (100 m)
can and should be expected. Generally, po-
sition errors will be corrected within a few
seconds.When the vehicle is receiving signals from
satellites, the “GPS” mark appears at the
top left of the screen.
The GPS signal may be physically obstruct-
ed, leading to inaccurate vehicle position on
the map screen. Tunnels, tall buildings,
trucks, or even the placement of objects on
the instrument panel may obstruct the GPS
signals.
The GPS satellites may not send signals due
to repairs or improvements being made to
them.
Even when the navigation system is receiv-
ing clear GPS signals, the vehicle position
may not be shown accurately or inappropri-
ate route guidance may occur in some cas-
es.
LIMITATIONS OF THE
NAVIGATION SYSTEM
This navigation system calculates the
current position using satellite signals,
various vehicle signals, map data, etc.
However, an accurate position may not
be shown depending on satellite condi-
tions, road configuration, vehicle condi-
tion or other circumstances.
NOTICE
●
The installation of window tinting may
obstruct the GPS signals. Most window
tinting contains some metallic content
that will interfere with GPS signal recep-
tion of the antenna in the instrument
panel. We advise against the use of win-
dow tinting on vehicles equipped with
navigation systems.

zAccurate current 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 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 direction by going forward and backward, or turning
on a turntable in a 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.
• When using tires that are smaller or larger than the factory specifications.
• When the tire pressure in any of the 4 tires is not correct. z
Inappropriate route guidance may occur in
the following cases:
• When turning at an intersection off the
designated route guidance.
• If you set more than 1 destination but skip any of them, auto reroute will display a
route returning to the destination on the
previous route.
• 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.
• During high speed driving, it may take a long time for auto reroute to operate. In
auto reroute, a detour route may be
shown.
• After auto reroute, the route may not be changed.
• If an unnecessary U-turn is shown or announced.
• If a location has multiple names and the system announces 1 or more of them.
• When a route cannot 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, season or other reasons.
• The road and map data stored in the navi- gation system may not be complete or
may not be the latest version.
z If the vehicle cannot receive GPS signals,
the current position can be adjusted
manually. For information on setting the
current position calibration: →P. 1 5 5

INFORMATION
●This navigation system uses tire turning
data and is designed to work with factory-
specified tires for the vehicle. Installing
tires that are larger or smaller than the
originally equipped diameter may cause
inaccurate display of the current position.
The tire pressure also affects the diame-
ter of the tires, so make sure that the tire
pressure of all 4 tires is correct.
