– If it is impossible to reach the destination
or waypoints because of traffic
regulations, etc.
– If the only route to reach the destination
or waypoints is extremely complicated.
– If the destination, current vehicle position
or waypoint is within the “Avoid Area”.
– If a part of the route is included in the
“Avoid Area”.
● The following may occur when the route is
displayed:
– If you calculate a route on a main road,
the starting point of the route may not ex-
actly match the current vehicle location.
– The endpoint of the route may not exactly
match the destination.
– If you calculate a route on a main road,
the system may display a route from an-
other main road. This may be because
the position of the vehicle icon is not
accurate. In this case, park the vehicle in
a safe location and reset the vehicle icon,
or continue driving to see if the position
of the vehicle icon is automatically ad-
justed before recalculating the route.
– There are cases in which the system
shows an indirect route to reach the des-
tination or waypoints, if you set them
from stored or facility information. In or-
der to correct this, you must be careful
about the traffic direction, especially
when lanes with different travel direc-
tions are shown separately, such as in-
terchanges and service areas.
– This system makes no distinction be-
tween limited traffic control and total
control (blockage). It may show an indi-
rect route even if the road is usable.
– Even if the freeway preference is set to
OFF, a route that uses the freeway may
be suggested.
– Even if the preference is set to OFF, a
route that uses a ferry line may be
suggested.
– Ferry lines, excluding those that are only
for pedestrians, bicycles and
motorcycles, are stored in this system.
Take into consideration the travel time re-
quired and operational condition before
deciding whether to use them or not.
INFO:
The system will only announce street names
when the system language is set to English.
Street names are not announced when the sys-
tem is set to Français (French) or Español
(Spanish).
BASICS OF VOICE GUIDANCE
Voice guidance announces which direction to
turn when approaching an intersection in which
a turn is necessary.
NOTE:
● There may be some cases in which voice
guidance and actual road conditions do
not correspond. This may occur because
of discrepancies between the actual
road and the information on the map
data, or it is due to the vehicle’s speed.
● In case voice guidance does not corre-
spond to the actual road conditions, fol-
low the information obtained from traf-
fic signs or notices on the road.
● Route guidance provided by the naviga-
tion system does not take carpool lane
driving into consideration, especially
when carpool lanes are separated from
other road lanes.
