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.
• |
Basement parking structures
|
• |
Underneath an overpass
|
• |
Roads within forested areas
|
• |
Areas near high rise buildings
|
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)
