Description and Operation

Description

Navigation System Limitations / GPS Signal Reception Condition: Because GPS satellite signals are received/transmitted in straight lines, reception may not work if masking objects are located on or near the GPS antenna, or when traveling in the following locations.

• Tunnels
• Underground parking structures
• Under elevated roads
• Roads through forested areas
• Areas near high-rise buildings
• Canyon roads

Vehicle Position Display

1. 1
   If multipath errors occur due to reflections from buildings or related causes, the current position mark on the navigation screen may differ from the actual vehicle position.
2. 2
   The vehicle position on the navigation display may differ from the actual position if the vehicle is driven for a short period while being towed or transported; the vehicle position will be corrected through map matching or GPS information (in some cases, this may take several minutes).

   • When driving on a Y-shaped narrow-angle road, the current position may be displayed in the opposite direction.
   • If the vehicle is loaded onto a car carrier, the current position mark may stop at the last position before loading.
   • When driving on a spiral road.
   • When driving in mountainous areas with steep curves or sudden braking.
   • When exiting onto a road after being in an underground parking structure, a building parking structure, or a turn with many rotations.
   • When tires have been recently replaced (especially after using temporary spare or non-studded tires).
   • If the battery terminal has been disconnected.
   • When driving on city streets, the current position may be displayed on the opposite side of the road or in an off-road position.
   • When the scale level is changed from the maximum scale level to another scale level, the current position mark may be displayed on a different road.
   • When driving in heavy traffic with frequent stops or at intersections.
   • When driving on slippery roads, such as deep sand, snow, etc.
   • When driving with snow chains installed.
   • When using tires of an incorrect size.
   • When the tire pressure differs between the four tires.
   • When replacing a worn or used tire (especially a non-studded tire that has been in use for a second season, etc.)
   • When driving near high-rise buildings.
   • If a roof rack is installed.
   • When driving at high speeds or when calculating a long-distance route.

Route Guidance: Proper route guidance may not be performed due to search conditions or driving position.

• On a straight road, a straight-ahead instruction may be given.
• Guidance may not be given even when turning at an intersection.
• There are certain intersections where guidance may not be provided.
• Route guidance may indicate entry into a restricted area (No Entry, road under construction, etc.).
• Guidance may be provided to a location away from the actual destination if roads leading to the actual destination do not exist or are too narrow.
• Incorrect voice guidance may be given if the vehicle leaves the set route (example: a turn is made at an intersection while the navigation system instructed to go straight).
• Map data may be missing or incorrect, which may make route guidance impossible for the given destination.

Route Recalculation The following phenomena may occur after route recalculation.

• Guidance may be given to a position different from the current position when turning at an intersection.
• Route recalculation may take longer when driving at high speeds.
• Route guidance may indicate a U-turn at a location where a U-turn is prohibited.
• Route guidance may indicate entry into a restricted area (No Entry, road under construction, etc.).
• Guidance may be provided to a location away from the actual destination if roads leading to the actual destination do not exist or are too narrow.
• Incorrect voice guidance may be given if the vehicle leaves the set route (example: a turn is made at an intersection while the navigation system instructed to go straight).
