Accurate current position may not be
shown in the following cases:
• When driving on a small angled Y-
shaped road.
• 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 parallel.
• After moving by ferry or vehicle carrier.
• When a long route is searched during high speed driving.
• When driving without setting the current position calibration correctly.
• After repeating a change of direction by going forward and backward, or turning
on a turntable in a parking lot.
• When leaving a covered parking lot or 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 larger than the factory specifications.
• When the tire pressure in any of the 4
tires 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 dis-
play 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 or 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.
 If the vehicle cannot receive GPS sig-
nals, the current position can be
adjusted manually. For information on
setting the current position calibration:
→P. 2 4 8
 After replacing a tire: →P. 2 4 9

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