When driving on a winding road.
When driving on a slippery road such as
in sand, gravel, snow, etc.
When driving on a long straight road.
When freeway and surface streets run in

parking garage.
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 larg-
er than the factory specifications.When the tire pressure in any of the four
tires is not correct.
INFORMATION
If your vehicle cannot receive GPS sig-
nals, you can correct the current posi-
tion manually. For information on set-

see page lxxxviii.

(b) Inappropriate route guidance
may occur in the following cases:
When turning at an intersection off the
designated route guidance.
If you set more than one destination but
skip any of them, auto reroute will display a
route returning to the destination on the pre-
vious 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.
It may take a long time to operate auto re-
route during high speed driving. In auto re-
route, a detour route may be shown.
After auto reroute, the route may not be
changed.
An unnecessary U−turn may be shown
or announced.
A location may have multiple names and
the system will announce one or more.
Some routes may not 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 or season or other reason.
The road and map data stored in your
navigation system may not be complete or
may not be the latest version.
After replacing the tire, implement the
operation described in the “ Tire
change calibration”. (For details, see
page xc.)
This navigation system uses the tire turning
data and is designed to work with factory−
specified tires for your vehicle. Installing
tires that are larger or smaller than the origi-
nally equipped diameter may cause inaccu-
rate display of the vehicle’s position. The tire
pressure also affects the diameter of the
tires so please make sure the tire pressure
of all four tires is correct.
