Dodge 2009 Viper - Manual (Page 130)

NOTE: There is a varying temperature differential be-
tween the upper and lower outlets for added comfort.
The warmer air goes to the floor outlets. This feature
provides improved comfort during sunny but cool con-
ditions.
• Floor
Air is directed through the floor outlets with a
lesser amount through the defrost outlets.
• Defrost/Floor
Air is directed through the windshield defrost and
the floor outlets. This setting works best in cold or
snowy conditions that require extra heat at the
windshield. This setting is good for maintaining comfort
while reducing moisture on the windshield.
• Defrost
Air is directed through the windshield defrost
outlet. Use this mode with maximum fan and
temperature settings for best windshield defrosting.
NOTE: The air conditioning compressor operates in this
mode. This dehumidifies the air to help dry the wind-
shield. To improve fuel economy, leave in the Defrost
mode only when necessary.
Air Conditioning Control
With the fan control in the ON position, push the
A/C button to turn on the air conditioning com-
pressor. An indicator light above the button shows
that the Air Conditioning compressor is on. Conditioned
air is now directed through the outlets selected. Pushing
the button a second time turns the compressor OFF.
Slight changes in engine speed or power may be noticed
when the compressor is on. This is a normal occurrence
since the compressor will cycle on and off to maintain
comfort and increase fuel economy.
NOTE: If your air conditioning performance seems
lower than expected, check the front of the A/C con-
denser for an accumulation of dirt or insects.
