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 |
• |
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) |
