2018 FIAT 500E cooling

E-Park is activated when the driver pushes the PARK
button. An electric motor activates the parking pawl and
locks the single-speed transmission when the vehicle is
placed into PARK. This will prevent any unwanted move-
ment of the vehicle.
NOTE:The engagement of the E-Park can be heard when
there is no noise in the interior of the vehicle, this is a
normal condition.
Climate Control (HVAC System)
Your 500e is equipped with an Automatic Temperature
Control (ATC) HVAC system. This HVAC system utilizes a
humidity sensor, cabin sensor, and ambient temperature
sensor to choose operation mode and control cabin com-
fort. These components allow the controller to operate the
HVAC system in a very efficient manner to maximize
driving range.
Your 500e also uses an electric air heater to provide heat to
the cabin.
Electric Air Conditioning Compressor
Your 500e uses an electric air conditioning compressor. The
air conditioning compressor is powered by the high volt-
age battery system and is used to cool the vehicle occu-
pants and the high voltage battery while the vehicle is
being driven or when it is being charged.
The high voltage battery may require cooling to keep the
vehicle running. The air conditioning compressor activates
without any input from the occupant.
NOTE: The AC system helps cool the high voltage battery.
If the air conditioning system should require service, see an
authorized dealer as soon as possible.
Electric Power Steering
Your vehicle is equipped with an Electric Power Steering
(EPS) system. The power steering system requires no
maintenance and operates without the use of power steer-
ing fluid.

NOTE:
•It is not necessary to move the temperature settings for
cold or hot vehicles. The system automatically adjusts
the temperature, mode, and blower speed to provide
comfort as quickly as possible.
• The temperature can be displayed in U.S. or Metric units
by selecting the US/Metric customer-programmable fea-
ture.
To provide you with maximum comfort in the Automatic
mode during cold start-ups, the blower fan remains on low
until the vehicle warms up. The blower increases in speed
and transition into Auto mode.
Manual Operation Override
This system offers a full complement of manual override
features. The AUTO symbol in the front ATC display will
be turned off when the system is being used in the manual
mode.
NOTE: The system will not automatically sense the pres-
ence of fog, mist or ice on the windshield. Defrost mode
must be manually selected to clear the windshield and side
glass.
Operating Tips
NOTE: Refer to the chart at the end of this section for
suggested control settings for various weather conditions.
Summer Operation
The vehicle cooling system must be protected with a
high-quality antifreeze coolant to provide proper corrosion
protection and to protect against vehicle overheating. OAT
coolant (conforming to MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the vehicle 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.
Vacation/Storage
Before 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 fresh air with the
blower setting on high. This ensures adequate system
lubrication to minimize the possibility of compressor dam-
age when the system is started again.

Power Electronics And Battery Thermal
Management Systems — Coolant Level Check
The coolant expansion bottles provides a quick visual
method for determining that the coolant level is adequate.
With the vehicle off and coolant at ambient temperature,
the level of the coolant (antifreeze) in the bottles should be
between the bottom and top lines marked “MIN-MAX
FILL RANGE”.
As long as the vehicle operating temperature is satisfactory,
the coolant bottles need only be checked once a month.When additional coolant (antifreeze) is needed to maintain
the proper level, it should be added to the coolant bottles.
Do not overfill.
Check the Power Electronics and Battery Thermal Manage-
ment Systems coolant (antifreeze) protection every 12
months (before the onset of freezing weather, where appli-
cable).
Maintain coolant (antifreeze) concentration at a minimum
of 50% Mopar Antifreeze/Coolant 10 Year/150,000 Mile
Formula OAT (Organic Additive Technology) and
distilled/deionized water for proper corrosion protection.
Check the coolant bottles tubing for brittle rubber, crack-
ing, tears, cuts and tightness of the connection at the bottles
and radiator. Inspect the entire system for leaks.
Check the front of the A/C condenser for any accumula-
tion of bugs, leaves, etc. If dirty, clean by gently spraying
water from a garden hose vertically down the face of the
condenser.
NOTE:
DO NOT REMOVE THE COOLANT PRESSURE
CAP WHEN THE COOLING SYSTEM IS HOT.

220 SERVICING AND MAINTENANCE

WARNING!
You or others can be badly burned by hot coolant
(antifreeze) or steam from your radiator. If you see or
hear steam coming from under the hood, do not open
the hood until the radiator has had time to cool. Never
try to open a cooling system pressure cap when the
radiator is hot.
Power Electronics And Battery Thermal
Management Systems — Cooling Pressure Caps
The caps must be fully tightened to prevent loss of coolant
(antifreeze).
The caps should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.
NOTE:
•The pressure caps on the reservoirs are unique and rated
at 5 PSI (34.5 kPa).
• Use only Mopar replacement parts.
WARNING!
•The warning words “DO NOT OPEN HOT” on the
cooling system pressure cap are a safety precaution.
Never add coolant (antifreeze) when the cooling
system is overheated. Do not loosen or remove the
cap to cool an overheated cooling system. Heat
causes pressure to build up in the cooling system. To
prevent scalding or injury, do not remove the pres-
sure cap while the system is hot or under pressure.

SERVICING AND MAINTENANCE 221

WARNING!(Continued)
•Do not use a pressure cap other than the one speci-
fied for your vehicle. Personal injury or vehicle
damage may result.
Selection Of Coolant
Refer to “Fluids And Lubricants” in “Technical Specifica-
tions” for further information.
CAUTION!
•Mixing of coolant (antifreeze) other than specified
Organic Additive Technology (OAT) coolant (anti-
freeze), may result in cooling system damage and
may decrease corrosion protection. Organic Additive
Technology (OAT) coolant is different and should
not be mixed with Hybrid Organic Additive Tech-
nology (HOAT) coolant (antifreeze). If a non-OAT
coolant (antifreeze) is introduced into the cooling
system in an emergency, it should be replaced with
the specified coolant (antifreeze) as soon as possible.
(Continued)
CAUTION! (Continued)
•Do not use water alone or alcohol-based coolant
(antifreeze) products. Do not use additional rust
inhibitors or antirust products, as they may not be
compatible with the radiator coolant and may plug
the radiator.
• This vehicle has not been designed for use with
propylene glycol-based coolant (antifreeze). Use of
propylene glycol-based coolant (antifreeze) is not
recommended.
Adding Coolant
Your vehicle has been built with cooling systems that allow
extended maintenance intervals. This coolant (antifreeze)
can be used up to ten years or 150,000 miles (240,000 km)
before replacement. To prevent reducing this extended
maintenance period, it is important that you use the same
coolant (antifreeze) throughout the life of your vehicle.
Please review these recommendations for using Organic
Additive Technology (OAT) coolant (antifreeze).
