Route setting information
Route search specifications
Your navigation system sets a route to your
destination by applying certain built-in rules to
the map data. This section provides some use-
ful information about how a route is set.
CAUTION
When a route is calculated, the route and voice
guidance for the route are automatically set.
Also, for day or time traffic regulations, only infor-
mation about traffic regulations at the time when
the route was calculated is shown. One-way
streets and street closures may not be taken into
consideration. For example, if a street is open dur-
ing the morning only, but you arrive later, it would
be against the traffic regulations so you cannot
drive along the set route. When driving, please
follow the actual traffic signs. Also, the system
may not know some traffic regulations.
! The calculated route is one example of the
route to your destination decided by the na-
vigation system while taking the type of
streets or traffic regulations into account. It
is not necessarily an optimum route. (In
some cases, you may not be able to set the
streets you want to pass. If you need to
pass a certain street, set the waypoint on
that street.)
! If the destination is too far, there may be in-
stances where the route cannot be set. (If
you want to set a long-distance route going
across several areas, set waypoints along
the way.)
! During voice guidance, turns and intersec-
tions from the freeway are announced.
However, if you pass intersections, turns,
and other guide points in rapid succession,
some may delay or not be announced.
! It is possible that guidance may direct you
off a freeway and then back on again.
! In some cases, the route may require you
to travel in the opposite direction to your
current heading. In such cases, you are in-
structed to turn around, so please turn
around safely by following the actual traffic
rules.
! In some cases, a route may begin on the
opposite side of a railway or river from your
actual current location. If this happens,
drive towards your destination for a while,
and try route calculation again.
! When there is a traffic congestion ahead, if
driving through the traffic congestion is
better than taking the detour, a detour
route may not be suggested.
! There may be instances when the starting
point, the waypoint and the destination
point are not on the highlighted route.
