NISSAN 2012 Altima Sedan - Navigation System Owner's Manual - Manual (Page 143)

● If ЉUse Time Restricted RoadsЉ is deactivated,
the system calculates a route without any
consideration of the regulations concerning
the time or day of the week. Therefore, the
suggested route may include a road subject
to traffic regulations concerning the time or
day of the week. When driving along the
route, always follow all traffic regulations re-
gardless of whether
ЉUse Time Restricted
Roads Љ is ON or OFF.
● If the system cannot calculate any alternative
routes, it displays the previous route.
● If the vehicle overly deviates from the sug-
gested route, the system calculates a new
route.
● Statistical traffic information is based on pre-
vious traffic data. When the traffic situation
rapidly changes due to unexpected accidents,
construction
work, traffic restrictions,
emergencies, etc., the prediction accuracy of
the system may be reduced.
● Traffic jam information displayed on the map
screen is not statistical traffic information.
● When ЉUse Statistical Traffic InformationЉ is
turned on, the system may lead to a road
where a traffic jam occurs or to a detour even
though the shortest route does not have a
traffic jam.
● Even when ЉUse Real Time Traffic InformationЉ
is turned on, if traffic information has not been
provided for the area, sometimes it is possible
that a detour will not be indicated in a location
where a traffic jam occurs.
● The system may not lead to a detour if traffic
closure or a traffic jam occurs far from the
present location.
● The system calculates to reduce the time re-
quired for the entire route from the start to
destination. If there are no appropriate routes,
the system may lead to a route where a traffic
jam occurs instead of leading to a detour.
● This system can learn and memorize the route
that is most frequently used. However, de-
spite driving on the same route several times
so that the system can learn the route, the
system may have difficulty learning the route
under the following conditions:
– ЉUse Time Restricted RoadЉ is turned on.
–
ЉUse Real Time Traffic InfoЉ is turned on.
Various guidance information can be set to be
played during route guidance and activate or de-
activate route and/or voice guidance.
