●When Wi-Fi® hotspot is off, no
item is displayed.
The amount displayed does not
always correspond with the
amount displayed on the Blue-
tooth

The amount of battery charge
left may not be displayed
depending on the type of the
Bluetooth

used in the following conditions
and/or places:
The cellular phone is obstructed
by certain objects (such as
when it is behind the seat or in
the glove box or console box).
The cellular phone is touching or
is covered with metal materials.
Leave the Bluetooth

place where the condition of the
Bluetooth
® connection is good.

1143-5. Tips for operating the navigation system
3-5.Tips for operating the navigation system
The Global Positioning System
(GPS) developed and operated
by the U.S. Department of
Defense provides an accurate
current position, normally using
4 or more satellites, and in some
case 3 satellites. The GPS sys-
tem has a certain level of inac-
curacy. While the navigation
system compensates for this
most of the time, occasional
positioning errors of up to 300 ft.
(100 m) can and should be
expected. Generally, position
errors will be corrected within a
few seconds.
When the vehicle is not receiv-
ing signals from satellites, the
unreceived GPS mark appears
on the map screen. When the
vehicle is receiving the signals,
the unreceived GPS mark does not appear on the map screen.
The GPS signal may be physi-
cally obstructed, leading to inac-
curate vehicle position on the
map screen. Tunnels, tall build-
ings, trucks, or even the place-
ment 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 sys-
tem is receiving clear GPS sig-
nals, the vehicle position may
not be shown accurately or inap-
propriate route guidance may
occur in some cases.

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.
GPS (Global Position-
ing System)
This navigation system cal-
culates the current position
using satellite signals, vari-
ous vehicle signals, map
data, etc. However, an accu-
rate position may not be
shown depending on satel-
lite conditions, road config-
uration, vehicle condition or
other circumstances.
Limitations of the naviga-
tion system
NOTICE
●The installation of window tint-
ing may obstruct the GPS sig-
nals. Most window tinting
contains some metallic content
that will interfere with GPS sig-
nal reception of the antenna in
the instrument panel. We advise
against the use of window tint-
ing on vehicles equipped with
navigation systems.
