Tire Calibrate

As the vehicle moves, the navigation system receives speed pulses from the PCM. These pulses are converted
using a conversion factor to a mph speed that moves the vehicle position (VP) on the map. The navigation
system has an internal tuning function that generates and refines this factor based on actual driving. The "Level"
indicates the status of the tuning. At navigation initialization, it begins at 0, and increases to 10 as the
navigation system is used.

z

The "Auto Tuning" is factory set to "ON", and should remain on.

z

The "LEVEL" indicates the tuning status. If it is less than 10, the unit is still calibrating.

z

The "Tire-Cal. Tuning" and the "Set" button should not be used. It is for factory use only.

Trip Calibrate

By holding down the MENU button while on the "Trip Information" screen, you will see the screen below. This
screen allows you to adjust the vehicle range (distance to empty).

z

"Calc. RANGE" is the calculated value.

z

"Disp. RANGE" is the distance displayed on the trip computer "Range" field. If it reads "0", the vehicle
will have enough fuel to travel approximately 20 miles.

z

Range Tuning can be adjusted "+" or "-" to adjust the range to empty. It is recommended that this value
not be changed.

NOTE:

Setting the range offset too low (+10) could result in the vehicle running out of
gas before the display reads "0". Make changes slowly when changing this
value.

Solar Angle

This screen is used to graphically display the sun's position as determined by GPS. The Navi System uses the
sun's angle, along with the sunlight sensor to control the driver/passenger A/C air flow. The heat that must be
removed by the A/C unit varies, depending on the angle of the sun entering the vehicle. This screen is for
factory use only, and should not be adjusted.

z

The screen shows a circular diagram of the sky oriented in the direction that the vehicle is pointing.
During daylight hours a red dot is shown, representing the direction and elevation of the sun. The outer
circle represents the horizon (0 degrees elevation). The middle circle is 30 degrees, the center circle is 60
degrees, and the very center is directly overhead (90 degrees).

z

The "Auto button" should always be on (yellow).

z

The "Angle", "Dir", and "Reliability" settings are used by the factory to simulate the sun's position for
debugging this function.

NOTE:

This model does not use this feature.
