Limitations Of The Navigation system

GPS Signal Reception State
As the GPS satellite frequency is received/transmitted in straight lines, reception may not work if hiding devices are placed on or near the GPS antenna or when traveling through the following locations.

• | Tunnels

• | Basement parking structures

• | Underneath an overpass

• | Roads within forested areas

• | Areas near high rise buildings

• | Roads within canyons

Vehicle Position Display

1. | If multipass errors occur due to reflections from buildings or related causes, the current position mark on the navigation may differ from the actual position of the vehicle.

2. | The position of the vehicle on the navigation may be different from the actual position if the vehicle is under the situation. Driving a vehicle for a short period of time will correct the position on thenavigation through map matching or GPS information.

A. | When driving on a Y-shaped road with a narrow angle, the current position may be displayed in the opposite direction.

B. | If the vehicle is loaded onto a car transport vehicle, the current position mark may be stalled on the last position prior to loading.

C. | When driving on a spiral-shaped road.

D. | When driving in mountain regions with sharp turns or sudden brakes.

E. | When entering a road after having been in an underground parking structure, building parking structure, or turnable with many rotations.

F. | When the tires have recently been replaced (Especially upon use of spare or studless tires)

G. | If the battery terminal is removed.

H. | When driving in city streets, the current position may be displayed on the opposite side or on an off-road position.

I. | When changing the zoom level from the maximum zoom in level to a different zoom level, the current position mark may be displayed on a different road.

J. | When driving in heavy traffic with frequent go · stops in traffic or intersections.

K. | When driving under slippery conditions, such as heavy sand, snow, etc.

L. | When driving with the tire chain in place.

M. | When using a tire with an incorrect size specification.

N. | When the tire pressure for the 4 tires are different.

O. | When the replacement tire is a worn or used tire (Especially studless tires having passed a 2nd seasons, etc.)

P. | When driving near high-rise buildings

Q. | If a roof carrier has been installed

R. | When driving under high speeds or having calculated a long-distance route.

Route Guidance
Suitable route guidance may not occur caused by search conditions or the driving position.

• | Guidance to go straight may be given while driving on a straight road.

• | Guidance may not be given even when having turned at an intersection.

• | There are certain intersections in which guidance may not occur.

• | A route guidance signaling entrance into a no enter zone may occur (No enter zone, road under construction, etc.)

• | Guidance may be given to a position removed from the actual destination if roads to reach the actual destination do not exist or are too narrow.

• | Faulty voice guidance may be given if the vehicle breaks from the designated route (ex : if a turn is made at an intersection while the navigation provided guidance to go straight).

• | Map Data may be missing or incorrect causing route guidance to not be given.

Route Re-calculation
The following phenomena may occur after conducting route recalculation.

• | Guidance may be given to a position differing from the current position when turning at an intersection.

• | Route recalculation may take a longer period of time when driving under high speeds.

• | A route guidance signaling for a U-Turn in a No U-Turn location may occur.

• | A route guidance signaling entrance into a no enter zone may occur (No enter zone, road under construction, etc).

• | Guidance may be given to a position removed from the actual destination do not exist or are too narrow.

• | Faulty voice guidance may be given if the vehicle breaks from the designated route (ex : if a turn is made at an intersection while the navigation provided guidance to go straight)
