If you join the road after driving
around a large parking lot.
When you drive around a traffic circle.
When starting driving immediately
after starting the engine.
Your navigation system sets a route to your
destination by applying certain built-in
rules to the map data. This section provides
some useful 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 information about
traffic regulations applicable at the time
when the route was calculated is
considered. One-way streets and street
closures may not be taken into
consideration. For example, if a street is
open during 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 navigation 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 take. If
you need to take a certain street, set a
waypoint on that street.)
•
If the destination is too far, there may be
instances 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
intersections from the freeway are
announced. However, if you pass
intersections, turns, and other guidance
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
instructed 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.
