28 Navigation Functions
Route Search Methods
• The route displayed in the route guidance
is a reference route to the destination. It
is not necessarily the shortest route. This
route guidance also does not take traffic
congestion information into account.
• Not all roads are used in route guidance.
• Routes using ferries are set to be less
recommended than normal roads. Therefore,
even when a ferry provides a quicker route
to the destination, a route not using the ferry
may be displayed.
• When a toll road interchange, parking area,
or service area is set as the destination or
as a waypoint, select from an establishment
search or from a freeway simplified map and
set without scrolling the map.
• Sometimes, the route is not the same as the
one prepared previously even though the
same locations were set as the destination
and waypoints.
• Sometimes routes are displayed that include
pedestrian ways, stairs, etc. that are not
passable by vehicle.
• If there is no road to the destination or only
narrow roads, a route may be displayed
that goes to some place apart from the
destination.
• Because searches are carried out passing
alongside establishments, depending on the
road configuration, roundabout routes may
be displayed.
• Sometimes routes are searched that take
traffic rule information into account.
• Sometimes, some temporary rules are not
taken into account or the time for which
they are applied differs from when they are
actually in effect.
Route Guidance
• When your car is driving on the searched
route, this displays the distance until the
destination or the next waypoint.
• When your car is driving off the searched
route, this displays the distance from the
point where you left the route until the
destination or the next waypoint.
• The display of the estimated time of arrival
at the destination is calculated based on the
remaining time data in the map data and
learning trip information.
• Sometimes even though you need to turn
at a junction, the junction name is not in the
guidance and the junction is not covered in
the audio guidance.
• Sometimes left and right turn guidance
differs from the actual road configuration.
• When you go off the route, for example by
turning one junction too early, sometimes the
audio guidance continues for the route you
had been on.
• Sometimes the distance in the guidance is
slightly too high or too low.
Precautions for operating the
navigation
• During route guidance, always obey the
actual traffic regulations. Failure to do so
may cause a traffic accident.
• The route is searched using the map data on
the map card. Sometimes it may differ from
actual restrictions for construction, one-way
rules, and other traffic rules. Always obey
the actual traffic regulations.
• Traffic rules that depend on the time of
day reflect the time at which the route was
searched. When driving the route, always
obey the actual traffic regulations.
• The distance your car has traveled is
measured with the speed sensor (and this
speed is proportional to the rotation rate of
the tires).When the tires are new, if you have
non-standard tires, or if the tire air pressure
is not correct, error inputs the distance
measurement more easily and the location
of your car may not be displayed correctly.
• The route is a reference route to around the
destination. It is not the shortest route or the
route most free of traffic congestion.
• While you are driving, the amount of road
information displayed is restricted and some
roads may not be displayed.(For example,
narrow streets)
• If the distance to the destination is extremely
short or extremely long, route search may be
impossible.
• Even if you travel off the route, the route is
automatically recalculated.
• The estimated time of arrival varies with the
road conditions and how you drive.
