TIPS FOR THE NAVIGATION SYSTEM
GPS ( GLOBAL POSITIONING SYSTEM )
REGARDING ERRORS IN CURRENT POSITION DISPLAY
The system displays the vehicle current position based on GPS information and data from various sensors and road maps . However , when the radiowave signals from GPS satellites are weak or when signals are received from only two satellites or less , errors may occur in the position . Modifying or adjusting the system will not prevent these errors .
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 feet ( 100 m ) can and should be expected . Generally , position errors will be corrected within a few seconds .
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
� 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 .
