Before Thinking There is a Product Defect
The current position as shown on the navigation may differ from
the actual position under the following conditions.
The following occurrences are not malfunctions :
• When driving on Y-shaped roads
with narrow angles the current posi-
tion may be displayed in the oppo-
site direction
• Within city streets, the current posi-
tion may be displayed on the oppo-
site side or on an off-road position
• When changing the zoom level
from maximum to a different level,
the current position may become
displayed on a different road
• I f t h e v e h i c l e i s l o a d e d o n t o a
ferry or a car transport vehicle, the
current position may become stalled
on the last position prior to loading
• When driving on a spiral-shaped
road
• When driving in mountain regions
with sharp turns or sudden brakes
• When entering a road after passing
an underground parking structure,
building parking structure, or roads
with many rotations
• When driving in heavy traffic with
frequent starts and stops
• When driving under slippery condi-
tions, such as heavy sand, snow,
etc.
• When driving on spiral-shaped roads• When the tires have recently been
replaced (Especially upon use of
spare or studless tires).
• When using tires of improper size• When the tire pressure for the 4 tires
are different
• When the replacement tire is worn
or used (Especially studless tires
having passed a second season).
• When driving near high-rise build-
ings
• W h e n a r o o f c a r r i e r h a s b e e n
installed
• When a long distance route is calcu-
lated while driving on an expressway
In such cases, continued driving will
automatically enable the system
to conduct map matching or use
updated GPS information to provide
the current position (In such cases,
u p t o s e v e r a l m i n u t e s m a y b e
required)
Correct route guidance may not occur due to search conditions
or driving position.
The following occurrences are not malfunctions :
• Guidance to go straight may be
given while driving on a straight
road
• Guidance may not be given even
when having turned at an intersec-
tion
• There are certain intersections in
which guidance may not occur
• A route guidance signaling for a
u-turn may occur in some No u-turn
intersections
• Route guidance signaling entrance
i n t o a N o - e n t r y z o n e m a y o c c u r
(No-entry zone, road under construc-
tion, etc.)
• Guidance may be given to a position
that is not 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 away from the
designated route. (e.g. if a turn is
made at an intersection while the
navigation provided guidance to go
straight.)
These situations may occur after conducting route calculation.
The following occurrences are not malfunctions :
• Guidance may be given to a posi-
tion differing from the current posi-
tion when turning at an intersection
• When driving in high speeds, route
recalculation may take a longer
period of time
• R o u t e g u i d a n c e s i g n a l i n g f o r a
u-turn may occur in some No u-turn
intersections
• Route guidance signaling entrance
i n t o N o - e n t r y z o n e m a y o c c u r .
(No-entry zone, road under construc-
tion, 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 away from the
designated route (e.g. If a turn is
made at an intersection while the
navigation provided guidance to go
straight.)
