TIRE CHANGE CALIBRATION
The tire change calibration function will be
used when replacing the tires. This func-
tion will adjust the miscalculation caused
by the circumference difference between
the old and new tires. If this procedure is
not performed when the tires are replaced,
the current vehicle position mark may be
incorrectly displayed.
To perform a distance calibration pro-
cedure, touch “Tire Change” on the
“Calibration” screen.
The message appears and the quick dis-
tance calibration is automatically started.
A few seconds later, a map screen will be
displayed.

After replacing a tire, implement the op-
eration described in the “TIRE
CHANGE CALIBRATION”. (See page
114.)
This navigation system uses tire turning
data and is designed to work with factory−
specified tires for your vehicle. Installing
tires that are larger or smaller than the orig-
inally equipped diameter may cause inac-
curate 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. This system uses the maps of DENSO.
