Navigation system
• When a roof carrier is installed.
• When driving with tire chains installed.
• When the tires are worn.
• After replacing a tire or tires.
• When using tires that are smaller or
larger than the factory specifications.
• When the tire pressure in any of the 4
tires is not correct.
 If the vehicle cannot receive GPS
signals, the current position can be
adjusted manually. For information
on setting the current position cali-
bration: →P.96
 Inappropriate route guidance may
occur in the following cases:
• When turning at an intersection off the
designated route guidance.
• If you set more than 1 destination but skip
any of them, auto reroute will display a
route returning to the destination on the
previous route.
• When turning at an intersection for
which there is no route guidance.
• When passing through an intersection
for which there is no route guidance.
• During auto reroute, the route guidance
may not be available for the next turn to
the right or left.
• During high speed driving, it may take a
long time for auto reroute to operate. In
auto reroute, a detour route may be
shown.
• After auto reroute, the route may not be
changed.
• If an unnecessary U-turn is shown or
announced.
• If a location has multiple names and the
system announces 1 or more of them.
• When a route cannot be searched.
• If the route to your destination includes
gravel, unpaved roads or alleys, the
route guidance may not be shown.
• Your destination point might be shown
on the opposite side of the street.
• When a portion of the route has regula-
tions prohibiting the entry of the vehicle
that vary by time, season or other rea-
sons.
• The road and map data stored in the
navigation system may not be complete
or may not be the latest version.

● This navigation system uses tire turning
data and is designed to work with fac-
tory-specified tires for the vehicle. Install-
ing tires that are larger or smaller than the
originally equipped diameter may cause
inaccurate display of the current position.
The tire pressure also affects the diame-
ter of the tires, so make sure that the tire
pressure of all 4 tires is correct.
