rection of the current vehicle position
mark.
5. Touch “Enter”.
The map screen will be displayed.TIRE CHANGE CALIBRATION
The tire change calibration function will be
used when replacing the tires. This function
will adjust the mis−calculation caused by the
circumference difference between the old
and new tires. If this procedure is not per-
formed when tires are replaced, the current
vehicle position mark may be incorrectly dis-
played.
To perform a distance calibration proce-
dure, touch “Tire Change” on the “Cal-
ibration” screen.
The message appears and the quick distance
calibration is automatically started. A few
seconds later, a map screen will be displayed.

tion” on page 107.
(b) Inappropriate route guidance may oc-
cur in the following cases:
When turning at an intersection off the

The road and map data stored in your nav-

may not be the latest version.
After replacing the tire, implement the op-
eration described in the “ Current posi-
tion/tire change calibration”. (See page
107.)
This navigation system uses tire turning data
and is designed to work with factory−speci-
fied tires for your vehicle. Installing tires that
are larger or smaller than the originally
equipped diameter may cause inaccurate
display of the vehicle’s position. The tire pres-
sure also affects the diameter of the tires so
please make sure the tire pressure of all four
tires is correct.
