6. TIPS FOR THE NAVIGATION SYSTEM
1. GPS (GLOBAL POSITIONING SYSTEM)
The Global Positioning System (GPS)
developed and operated by the U.S. De-
partment of Defense provides an accu-
rate current position, normally using 4
or more satellites, and in some case 3
satellites. The GPS system has a certain
level of inaccuracy. While the naviga-
tion system compensates for this most
of the time, occasional positioning er-
rors of up to 100 yd. (100 m) can and
should be expected. Generally, position
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 ob-
structed, 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 re-
ceiving clear GPS signals, the vehicle
position 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 posi-
tion may not be shown depending on
satellite conditions, road configura-
tion, vehicle condition or other cir-
cumstances.
NOTICE
The installation of window tinting
may obstruct the GPS signals. Most
window tinting contains some metal-
lic content that will interfere with
GPS signal reception of the antenna
in the instrument panel. We advise
against the use of window 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 motorway and surface streets
run in parallel.
• After moving by ferry or vehicle car-
rier.
• When a long route is searched during
high speed driving.
• When driving without setting the cur-
rent 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 tyre chains
installed.
• When the tyres are worn.
• After replacing a tyre or tyres.
• When using tyres that are smaller or
larger than the factory specifications.
• When the tyre pressure in any of the 4
tyres 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
display a route returning to the desti-
nation 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 guid-
ance 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.
If the vehicle cannot receive GPS sig-
nals, the current position can be
adjusted manually. (P.171)

• Your destination point might be
shown on the opposite side of the
street.
• When a portion of the route has regu-
lations prohibiting the entry of the
vehicle that vary by time, season or
other reasons.
• The road and map data stored in the
navigation system may not be com-
plete or may not be the latest version.
After replacing a tyre: P.172
INFORMATION
This navigation system uses tyre turn-
ing data and is designed to work with
factory-specified tyres for the vehicle.
Installing tyres that are larger or
smaller than the originally equipped
diameter may cause inaccurate dis-
play of the current position. The tyre
pressure also affects the diameter of
the tyres, so make sure that the tyre
pressure of all 4 tyres is correct.
