6. NAVIGATION SYSTEM INFORMATION
1. LIMITATIONS OF THE NAVIGATION SYSTEM
The Global Positioning System (GPS) de-
veloped and operated by the U.S. Depart-
ment of Defense provides an accurate
current vehicle position, normally using 4
or more satellites, and in some case 3 sat-
ellites. The GPS system has a certain level
of inaccuracy. While the navigation system
will compensate for this most of the time,
occasional positioning errors of up to 300
feet (100 m) can and should be expected.
Generally, position errors will be corrected
within a few seconds.
The GPS signal may be physically ob-
structed, leading to inaccurate vehicle po-
sition on the map display. Tunnels, tall
buildings, trucks, or even the placement of
objects on the instrument panel may ob-
struct 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.

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.
• 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 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.
• 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.
This navigation system calculates the
current vehicle position using satellite
signals, various vehicle signals, map
data, etc. However, an accurate posi-
tion may not be shown depending on
satellite condition, road configuration,
vehicle condition or other circumstanc-
es.
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. We advise against
the use of window tinting on vehicles
equipped with navigation systems.

1. REAR VIEW MONITOR SYSTEM
1. REAR VIEW MONITOR SYSTEM OPERATION
1To display the rear view image on the
screen, the shift lever is in the “R” posi-
tion when the engine switch is in the
“ON” position.
If you move the shift lever out of the “R”
position, the screen returns to the previ-
ous screen.
The rear view monitor system assists
the driver by displaying an image of the
view behind the vehicle while backing
up.
The image is displayed in reverse on
the screen. This allows the image to
appear in the same manner as that of
the rear view mirror.CAUTION
●Never depend on the rear view monitor
system entirely when backing up.
Always make sure your intended path is
clear.
Use caution, just as you would when
backing up any vehicle.
● Never back up while looking only at the
screen. The image on the screen is dif-
ferent from actual conditions. Depicted
distances between objects and flat sur-
faces will differ from the actual dis-
tances. If you back up while looking only
at the screen, you may hit a vehicle, a
person or an object. When backing up,
be sure to check behind and all around
the vehicle visually and with mirrors
before proceeding.
● Do not use the system when the back
door, trunk or tailgate is not completely
closed.
● Use your own eyes to confirm the vehi-
cle’s surroundings, as the displayed
image may become faint or dark, and
moving images will be distorted, or not
entirely visible when the outside tem-
perature is low. When backing up, be
sure to check behind and all around the
vehicle visually and with mirror before
proceeding.
● Do not use the system in the following
cases:
• On icy or slick road surfaces, or in
snow.
• When using tire chains or emergency tires.
• On an uneven road, such as a slope.
 With rear view monitor guide lines (If
equipped)
● Always check the vehicle surrounding
area, because the guide lines are ancil-
lary lines.
● The guide lines are ancillary lines and
do not change even if the steering wheel
is turned.
