Condition 2 :whether to use motorway or not
Avoid Motorway :
Calculate a route that avoids motorway. (A route
using the motorway may be set if your destina-
tion is far away.)
• The system assumes the driver deviated either
intentionally or inadvertently from the route
and searches for another route (intelligent
rerouting). Depending on the situation, the
system may search a new route that does not
return to the original one.
• The calculated route is one example of the
route to your destination decided by the Navi-
gation System whilst taking the type of streets
or traffic regulations into account. It is not nec-
essarily an optimum route. (In some cases, you
may not be able to set the streets you want to
pass. If you want to pass a certain street, set
the way point on that street.)
• The route set by your Navigation System is
based on the assumption that the driver does
not know the area. Thus, the streets known to
local drivers, such as small streets or special
roads, may not be used for the set route.
• Some route options may become the same
route. If visiting points are set, or the route is
set by voice operation, only one route is calcu-
lated.
• Route setting is limited to the range of the disc
in use.
• 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 way points along the
way.)
• During voice guidance, turns and junctions
from the motorway are announced. However, if
you pass junctions, turns, and other guide
points in rapid succession, some may not be
announced.
• It is possible that guidance may direct you off a
motorway and then back on again.
• In some cases, the set 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, guidance may direct you past
your destination and then indicate a U-turn to
get back to it.

• In some cases, a route may begin on the oppo-
site side of a railway or river from your actual
current location. If this happens, drive towards
your destination for a while, and try route cal-
culation again.
• In the following cases, the route that passes
through an Area to Avoid may be set:
- when your vehicle is in the Area to Avoid
- when your destination or way points are in
the Area to Avoid
- when it is not possible to avoid doing so
• If a suitable route cannot be set in compliance
with the specified "Detour" distance, or your
preference to avoid motorways, toll roads, ferry
route, the setting or parameter may be
ignored.
• When there is a traffic jam ahead, if driving
through the traffic jam is better than taking the
detour, a detour route may not be set.
• There may be instances when the starting
point and the destination point are not on the
highlighted route.
• The number of roundabout exits displayed on
the screen may differ from the actual number
of roads.
• "Auto Reroute" function does not work in the
following cases:
- when your car is not on a street
- when your car is on a ferry
- when driving on a road inside a facility
- when driving on a roundabout

Route highlighting

• Once set, the route is highlighted in bright
green on the map.
• The immediate vicinity of your starting point
and destination may not be highlighted, and
neither will areas with particularly complex
road layouts. Consequently, the route may
appear to be cut off on the display, but voice
guidance will continue.

Intersection enlargement

• When "Close-up of Junction" is on, the map
scale increases to show more detail as you
approach an intersection.
• If the intersection is approached in a gentle
curve, the map displayed may differ from the
actual road layout.
