The GPS signal may be physically obstructed, leading to
inaccurate vehicle position on the map screen. Tunnels, tall
buildings, trucks, or even the placement 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 system is receiving clear GPS
signals, the vehicle position may not be shown accurately or
inappropriate route guidance may occur in some cases.
CAUTION
l The installation of window tinting may obstruct the GPS
signals. Most window tinting contains some metallic 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.
TIPS FOR THE NAVIGATION SYSTEM
● 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.
• 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.
• After repeating a change of direction by going
forward and backward, or turning on a turntable in
a parking lot.
• When leaving a covered parking lot or parking
garage.
• When a roof carrier is installed.
• When driving with tyre chains installed.
• When the tyres are worn.
• After replacing a tyre or tyres.
• When using tyres that are smaller or larger than the
factory specifications.
• When the tyre pressure in any of the 4 tyres is not
correct.
