Dodge 2009 Viper - Manual (Page 131)

Operating Tips
NOTE: Refer to the chart at the end of this section for
suggested control settings for various weather condi-
tions.
Summer Operation
The engine cooling system in air-conditioned vehicles
must be protected with a high-quality antifreeze coolant
to provide proper corrosion protection and to protect
against engine overheating. A 50% solution of ethylene
glycol antifreeze coolant in water is recommended. Refer
to “Maintenance Procedures” in Section 7 of this manual
for proper coolant selection.
Winter Operation
• Use the Defrost mode to direct cold air away from the
occupants during engine warm-up in cold weather.
• The blower air will heat faster in cold weather if you
use only the low blower speeds for the first ten
minutes of vehicle operation.
• Use of the air Recirculation mode during winter
months is not recommended because it may cause
window fogging.
Vacation Storage
Anytime you store your vehicle, or keep it out of service
(i.e., vacation) for two weeks or more, run the air
conditioning system at idle for about five minutes in the
fresh air and high blower setting. This will insure ad-
equate system lubrication to minimize the possibility of
compressor damage when the system is started again.
