temperature control in the blue area. The system will
bring in outside air and cool it.
On cool but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough.

side windows. To defrost the windows quickly, use
DEFROST with the temperature knob all the way in the

grid to remove fog from
the rear window. Press
the area labeled PUSH to
turn the defogger on.
