• When driving with tyre chains
installed.
• When the tyres are worn.
• After replacing a tyre or tyres.
• When using tyres that are smaller or
larger than the factory specifications.
• When the tyre pressure in any of the 4
tyres is not correct.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 desti-
nation 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 guid-
ance 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 regu-
lations prohibiting the entry of the
vehicle that vary by time or season or
other reasons.
• The road and map data stored in the
navigation system may not be com-
plete or may not be the latest version.
If the vehicle cannot receive GPS sig-
nals, the current position can be
adjusted manually. For information
on setting the current position cali-
bration, see page 152.

After replacing a tyre, implement the
operation described in the “TYRE
CHANGE CALIBRATION”. (See
page 153.)
INFORMATION
This navigation system uses tyre turn-
ing data and is designed to work with
factory-specified tyres for the vehicle.
Installing tyres that are larger or
smaller than the originally equipped
diameter may cause inaccurate dis-
play of the current position. The tyre
pressure also affects the diameter of
the tyres, so make sure that the tyre
pressure of all 4 tyres is correct.
