2016 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
movement 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 tempera-
ture sensor to choose operation mode and control cabin
comfort. These components allow the controller to oper-
ate 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
voltage battery system and is used to cool the vehicle
occupants 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 will
activate 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 your 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
steering fluid.

Climate Control Functions
Air Conditioning (A/C)
The Air Conditioning (A/C) button allows the operator
to manually activate or deactivate the air conditioning
system. When in A/C mode with the ATC set to a cool
temperature, dehumidified air flows through the air outlets. If Economy mode is desired, push the A/C
button to turn off the A/C mode in the ATC display and
deactivate the A/C system.
NOTE:
•
If the system is in Mix or Defrost Mode, the A/C can
be turned off, but the A/C system shall remain active
to prevent fogging of the windows.
• If fog or mist appears on the windshield or side glass,
select Defrost mode and adjust blower speed if
needed.
Recirculation Control
When outside air contains smoke, odors, or high humid-
ity, or if rapid cooling is desired, you may wish to
recirculate interior air by pushing the RECIRCULATION
control button. Recirculation mode should only be used
temporarily. The recirculation LED will illuminate when

WARNING!
•Take care to avoid the radiator cooling fan when-
ever the hood is raised. It can start anytime the
ignition switch is ON. You can be injured by
moving fan blades.
• Remove any metal jewelry such as rings, watch
bands and bracelets that could make an inadvertent
electrical contact. You could be seriously injured.
• Batteries contain sulfuric acid that can burn your
skin or eyes and generate hydrogen gas which is
flammable and explosive. Keep open flames or
sparks away from the battery.
1. Set the parking brake, place the transmission into PARK and turn the ignition to LOCK.
2. Turn off the heater, radio, and all unnecessary electri- cal accessories. 3. Remove the protective cover over the positive
(+)
battery post.
4. If using another vehicle to jump-start the battery, park the vehicle within the jumper cables reach, set the
parking brake and make sure the ignition is OFF.
WARNING!
Do not allow vehicles to touch each other as this
could establish a ground connection and personal
injury could result.
Jump-Starting Procedure
WARNING!
Failure to follow this jump-starting procedure could
result in personal injury or property damage due to
battery explosion.

Check the Power Electronics and Battery Thermal Man-
agement Systems coolant (antifreeze) protection every 12
months (before the onset of freezing weather, where
applicable).
Maintain coolant (antifreeze) concentration at a mini-
mum of 50% MOPAR Antifreeze/Coolant 10 Year/
150,000 Mile Formula OAT (Organic Additive Technol-
ogy) 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 accumu-
lation 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.
WARNING!
You or others can be badly burned by hot coolant
(antifreeze) or steam from your radiator. If you see or

WARNING!(Continued)
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 caps.
• 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
pressure cap while the system is hot or under
pressure.
• Do not use a pressure cap other than the one
specified for your vehicle. Personal injury or ve-
hicle damage may result.
Selection Of Coolant
Refer to “Fluids, Lubricants, And Genuine Parts” in
“Maintaining Your Vehicle” 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 Addi-
tive Technology (OAT) coolant is different and
should not be mixed with Hybrid Organic Additive
Technology (HOAT) coolant (antifreeze). If a non-
OAT coolant (antifreeze) is introduced into the
cooling system in an emergency, it should be re-
placed with the specified coolant (antifreeze) as
soon as possible.
• 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.
(Continued)
CAUTION! (Continued)
•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 (an-
tifreeze) 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).
296 MAINTAINING YOUR VEHICLE

When adding coolant (antifreeze):
•The manufacturer recommends using MOPAR
Antifreeze/Coolant 10 Year/150,000 Mile Formula
OAT (Organic Additive Technology).
• Mix a minimum solution of 50% OAT coolant (anti-
freeze) and distilled water. Use higher concentrations
(not to exceed 70%) if temperatures below -34ºF (-37ºC)
are anticipated.
• Use only high purity water such as distilled or deion-
ized water when mixing the water and coolant (anti-
freeze) solution. The use of lower quality water will
reduce the amount of corrosion protection in the
cooling systems.
Please note that it is the owners responsibility to maintain
the proper level of protection against freezing according
to the temperatures occurring in the area where the
vehicle is operated. NOTE:
Mixing coolant (antifreeze) types will decrease
the life of the Power Electronics and Battery Thermal
Management Systems coolant (antifreeze) and will re-
quire more frequent coolant (antifreeze) changes.
Power Electronics And Battery Thermal
Management Systems — Drain, Flush And Refill
Refer to “Maintenance Schedules” for the proper main-
tenance intervals.
If the coolant (antifreeze) is dirty or contains a consider-
able amount of sediment, clean and flush with a reliable
cooling system cleaner. Follow with a thorough rinsing to
remove all deposits and chemicals. Properly dispose of
old coolant (antifreeze) solution.
