MY TRAFFIC ROUTES
Specific routes (such as frequently
used routes) on which you wish to re-
ceive traffic information can be regis-
tered as “My Traffic Routes”. A route is
set by defining a start point and end
point, and can be adjusted by setting
up to 2 preferred roads.

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 in-
accuracy. While the navigation system
compensates for this most of the time, oc-
casional positioning errors of up to 300 ft.
(100 m) can and should be expected. Gen-
erally, position errors will be corrected
within a few seconds. When the vehicle is r
eceiving signals from
satellites, the “GPS” mark appears at the
top left of the screen.
The GPS signal may be physically ob-
structed, leading to inaccurate vehicle po-
sition on the map screen. Tunnels, tall
buildings, trucks, or even the placement of
objects on the control 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 re-
ceiving clear GPS signals, the vehicle po-
sition may not be shown accurately or
inappropriate route guidance may occur in
some cases.
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 con-
dition 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.

Accurate 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. 
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 dis-
play 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 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.
 If the vehicle cannot receive GPS sig-
nals, the current position can be
adjusted manually. For information on
setting the current position calibration:

 After replacing a tire:  P. 2 6 4

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

ABOUT THE MAP DATA
Map data for the navigation system is
contained in a SD card that is inserted
in the SD card slot.
Do not eject the SD card, as doing so
may deactivate the navigation system.
WA R N I N G
●Do not allow children to touch the SD
card. It may be accidently swallowed
and get stuck in the throat resulting in
death or serious injury.
NOTICE
●Do not edit or delete the map data on
the SD card, as doing so may deactivate
the navigation system.
● Take care not to lose the micro SD card,
as it is a small part that may easily
become lost when ejected or dropped.
