such as 15° C (60° F) or 32° C
(90° F)
.

Select a temperature setting that
is higher in hot weather and
lower in cold weather.

when it is not needed.
.
Only use defrost to clear the
windows.

the fan speed, air delivery, air
conditioning, and recirculation in
order to heat or cool the vehicle to
the desired temperature.
