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
obstruct the GPS signals.
The installation of window tinting may
also obstruct the GPS signals. Most win-
dow tinting contains some metallic con-
tent that will interfere with the GPS signal
reception. We recommend not to use the
window tinting on vehicles equipped with
navigation systems.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.

The tire change calibration function
should be used when the tires are re-
placed. This will adjust for any pos-

the old tires to the new ones. If this
procedure is not performed when tires
are replaced, the current vehicle posi-
tion mark may become incorrect.
To execute the fast distance tire calibra-
tion procedure, touch the
“Tire
