Operating Tips - Fiat 500X 2018 Owner's Manual

2. Adjust the temperature you would like the system to
maintain, by adjusting the driver, and passenger tem-
peratures. Once the desired temperature is displayed,
the system will achieve and automatically maintain that
comfort level.
3. When the system is set up for your comfort level, it is
not necessary to change the settings. You will experience
the greatest efficiency by simply allowing the system to
function automatically.
NOTE:
• It is not necessary to move the temperature settings. The
system automatically adjusts the temperature, mode,
and fan speed to provide comfort as quickly as possible.
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 fan will engage
immediately if the Defrost mode is selected, or by changing
the front blower knob setting.

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. OAT
coolant (conforming to MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is functioning
properly and the proper amount, type, and concentration
of coolant is used. Use of the Air Recirculation mode
during Winter months is not recommended, because it may
cause window fogging.
