BASIC FUNCTIONS

After replacing the tire, implement the
operation described in the “Current
position calibration”. (For details, see
page 95.)
This navigation system uses tire turning
data and is designed to work with factory −
specified tires for your Toyota. 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. Map database is made based on the
maps, 2008 edition of DENSO, whose
information source comes from
NAVTEQ maps, Tele Atlas maps and
infoUSA POIs.

POSITION/DIRECTION CALIBRATION
1. Move the cursor mark to your de-
sired point by operating the select and
scroll lever of the n avigation controller.
Push the
“ENTER” button on the navi-
gation controller.
2. Operate the select and scroll lever
of the navigation controller, so that the
screen direction is facing to your de-
sired direction.
Push the
“ENTER” button on the navi-
gation controller, and then the map screen
will be displayed. TIRE CHANGE CALIBRATION
The tire change calibration function
should be used when the tires are re-
placed.
This will adjust for any possible
change in tire circumference from the
old tires to the new ones. If this proce-
dure is not performed when tires are re-
placed, the current vehicle position
mark may become incorrect.
To execute the fast distance tire calibration
procedure, select the
“Tire change”switch on the “Calibration” screen.
The message appears and the fast dis-
tance calibration is automatically started.
A few seconds later, the map screen will be
displayed.
