Display:
When an obstacle is detected, the indica-
tor will flash yellow. The flashing speed be-
comes faster as the vehicle gets closer to
the obstacle. When the distance between
the vehicle and the obstacle is less than
about 0.8 ft. (25 cm), the indicator will illu-
minate in red.
Beeps:
As distance to the obstacle gets closer, the
interval of the intermittent sound gets
shorter, and then finally changes to a con-
tinuous sound when the distance between
the vehicle and the obstacle is less than
about 0.8 ft. (25 cm).

This navigation system calculates the
current vehicle position using satellite
signals, various vehicle signals, map
data, etc. However, the accurate posi-
tion may not be shown depending on
the satellite condition, road configura-
tion, vehicle condition or other circum-
stances.
The Global Positioning System (GPS) de-
veloped and operated by the U.S. Depart-
ment of Defense provides an accurate cur-
rent vehicle position, normally using 4 or
more satellites, and in some cases 3 satel-
lites. The GPS system has a certain level
of inaccuracy. While the navigation sys-
tem will compensate for this most of the
time, occasional positioning errors of up to
300 feet (100 m) can and should be expec-
ted. Generally, position errors will be cor-
rected within a few seconds.
When your vehicle is receiving signals
from the satellites, the “GPS” mark ap-
pears at the top left of the screen.
The GPS signal may be physically ob-
structed, leading to inaccurate vehicle
position 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
position may not be shown accurately or
inappropriate route guidance may occur in
some cases.
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.

(a) Accurate current vehicle position
may not be shown in the following
cases:
DWhen driving on a small angled Y−
shaped road.
DWhen driving on a winding road.
DWhen driving on a slippery road such
as in sand, gravel, snow, etc.
DWhen driving on a long straight road.
DWhen motorway and surface streets
run in parallel.
DAfter moving by ferry or vehicle carrier.
DWhen a long route is searched during
high speed driving.
DWhen driving without setting the cur-
rent position calibration correctly.
DAfter repeating a change of direction by
going forward and backward, or turning
on a turntable in the parking lot.
DWhen leaving a covered parking lot or
parking garage.
DWhen a roof carrier is installed.
DWhen driving with tire chains installed.
DWhen the tires are worn.
DAfter replacing a tire or tires.
DWhen using tires that are smaller or
larger than the factory specifications.
DWhen the tire pressure in any of the
four tires is not correct.
INFORMATION
If your vehicle cannot receive GPS
signals, you can correct the current
position manually. For information
on setting the current position cal-
ibration, see page 115.
(b) Inappropriate route guidance may
occur in the following cases:
DWhen turning at an intersection off the
designated route guidance.
DIf you set more than one destination but
skip any of them, auto reroute will dis-
play a route returning to the destination
on the previous route.
DWhen turning at an intersection for
which there is no route guidance.
DWhen passing through an intersection
for which there is no route guidance.
DDuring auto reroute, the route guid-
ance may not be available for the next
turn to the right or left.
DIt may take a long time to operate auto
reroute during high speed driving. In
auto reroute, a detour route may be
shown.
DAfter auto reroute, the route may not be
changed.
DAn unnecessary U −turn may be shown
or announced.
DA location may have multiple names
and the system will announce one or
more.
DSome routes may not be searched.
DIf the route to your destination includes
gravel, unpaved roads or alleys, the
route guidance may not be shown.
DYour destination point might be shown
on the opposite side of the street.
DWhen a portion of the route has regula-
tions prohibiting the entry of the vehicle
that vary by time or season or other
reasons.
DThe road and map data stored in your
navigation system may not be com-
plete or may not be the latest version.
