Operating Tips - Dodge Challenger SRT 392 2015 Operating Information Manual

To provide you with maximum comfort in the
Automatic mode, during cold start-ups the
blower fan will remain on low until the engine
warms up. The blower will increase in speed
and transition into Auto mode.
Manual Operation Override
The system allows for manual selection of
blower speed, air distribution mode, A/C status
and recirculation control.
The blower fan speed can be set to any fixed
speed by adjusting the blower control. The fan
will now operate at a fixed speed until additional
speeds are selected. This allows the front oc-
cupants to control the volume of air circulated in
the vehicle and cancel the Auto mode.
The operator can also select the direction of the
airflow by selecting one of the available mode
settings. A/C operation and Recirculation con-
trol can also be manually selected in Manual
operation.

NOTE:
Each of these features operates indepen-
dently from each other. If any feature is
controlled manually, temperature control
will continue to operate automatically.

Operating Tips

NOTE:
Refer to the chart at the end of this section
for suggested control settings for various
weather conditions.
Summer Operation
The engine cooling system must be protected
with a high-quality antifreeze coolant to provide
proper corrosion protection and to protect
against engine overheating. A solution of 50%
OAT (Organic Additive Technology) coolant that
meets the requirements of Chrysler Material
Standard MS-12106 and 50% water is recom-
mended. Refer to "Maintenance Procedures" in
"Maintaining Your Vehicle" for proper coolant
selection.
Winter Operation
Use of the air Recirculation mode during winter
months is not recommended because it may
cause window fogging.
Vacation Storage
Any time 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 ensure adequate system lubri-
cation to minimize the possibility of compressor
damage when the system is started again.
Window Fogging
Interior fogging on the windshield can be quickly
removed by turning the mode selector to De-
frost. The Defrost/Floor mode can be used to
maintain a clear windshield and provide suffi-
cient heating. If side window fogging becomes
objectionable, increase blower speed to im-
prove airflow and clearing of the side windows.
Vehicle windows tend to fog on the inside in mild
but rainy or humid weather.
