BASIC FUNCTIONS

When your vehicle is not receiving signals
from the satellites, the “GPS” mark does
not appear at 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 good 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:
When driving on a small angled Y−
shaped road.
When driving on a spiral 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 cur-
rent position calibration correctly.
After repeating a change of directions
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 the 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.
INFORMATION
If your vehicle cannot receive GPS
signals, you can correct the current
position manually. For the informa-
tion on setting the current position
calibration, see page 95.
