DEF V button
Press the DEF V button to obtain maximum
airflow to the windshield. Adjust the
temperature setting as required for defrosting.
The Display window will show the temperature
setting with the defrost symbol V to the left of
the temperature. When the outside temperature
is about 50˚F (10˚C) and above, the air will be
dehumidified to remove moisture. This will help
prevent fogging in humid weather.
OUTSIDE TEMP button
By pressing this button the temperature of the
air outside of the vehicle will show in the
display. The outside temperature will continue to
be displayed until the OUTSIDE TEMP button is
pressed again to cancel. If the selected
temperature setting is changed while the outside
temperature is displayed, the new selected
temperature will be displayed for 4 seconds after
it is changed. Then, the outside temperature will
return to the window. If a manual override is
pressed or the thumbwheel is rotated while the
outside temperature is displayed, the window
will show the change for 4 seconds. Then, the
outside temperature will return along with the
changed override selection.
