the sun may adequately warm your upper body, but your

in two ways.-Cool air
is directed 'toward your upper
body through the front instrument panel outlets, ,while
slightly warmed
air is directed through the heater outlet
at
your feet.
.The air conditioner compressor operates in all Air
Conditioning positions, and the Defrost position when
.the outside temperature is above
40 OF (4.5 C).

Heating
When outside temperatures are cold, 8liding:the upper .
lever to Heater and the' lower lever to :Warm will send,
heated air though the heater outlets, 'and-some through
