6. TIPS FOR THE NAVIGATION SYSTEM
1. GPS (GLOBAL POSITIONING SYSTEM)
LIMITATIONS OF THE
NAVIGATION SYSTEM
This navigation system calculates the current position using satellite signals, various vehicle signals, map data, etc.
However, an accurate position may not be shown depending on satellite conditions, road configuration, vehicle condition or other circumstances.
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 system has a certain level of inaccuracy. 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 receiving signals from satellites, the “GPS” mark appears at the top left of the screen.
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 control 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.
NOTICE
●
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.

6. TIPS FOR THE NAVIGATION SYSTEM
Accurate current position may not be shown in the following cases:
• When driving on a small angled Yshaped 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 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 current position calibration correctly.
• 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 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 4 tires is not correct.
If the vehicle cannot receive GPS signals, the current position can be adjusted manually. For information on setting the current position calibration:

Inappropriate route guidance may occur in the following cases:
• When turning at an intersection off the designated route guidance.
• If you set more than 1 destination but skip any of them, auto reroute will display a route returning to the destination on the previous route.
• When turning at an intersection for which there is no route guidance.
• When passing through an intersection for which there is no route guidance.
• During auto reroute, the route guidance may not be available for the next turn to the right or left.
• During high speed driving, it may take a long time for auto reroute to operate. In auto reroute, a detour route may be shown.
• After auto reroute, the route may not be changed.
• If an unnecessary U-turn is shown or announced.
• If a location has multiple names and the system announces 1 or more of them.
• When a route cannot be searched.
• If the route to your destination includes gravel, unpaved roads or alleys, the route guidance may not be shown.
• Your destination point might be shown on the opposite side of the street.
• When a portion of the route has regulations prohibiting the entry of the vehicle that vary by time or season or other reasons.
• The road and map data stored in the navigation system may not be complete or may not be the latest version.

After replacing a tire:
INFORMATION
●
This navigation system uses tire turning data and is designed to work with factory-specified tires for the vehicle.
Installing tires that are larger or smaller than the originally equipped diameter may cause inaccurate display of the current position. The tire pressure also affects the diameter of the tires, so make sure that the tire pressure of all 4 tires is correct.
