cooling FIAT 500E 2015 2.G Owners Manual

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.
16 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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
humidity, or if rapid cooling is desired, you may
wish to recirculate interior air by pushing the RECIRCU-
LATION control button. Recirculation mode should only
be used temporarily. The recirculation LED will illumi-
nate when this button is selected. Push the button a
second time to turn off the Recirculation mode LED and
allow outside air into the vehicle.
NOTE:In cold weather, use of Recirculation mode may lead
to excessive window fogging. The recirculation feature may
be unavailable (indicator light shall blink) if conditions exist
that could create fogging on the inside of the windshield. On
systems with Manual Climate Controls, the Recirculation
mode is not allowed in Defrost mode to improve window
clearing operation. Recirculation will be disabled automati-
cally if this mode is selected. Attempting to use Recirculation
while in this mode will cause the LED in the control button
to blink and then turn off.
Automatic Operation
1. Push the AUTO button on the Automatic Temperature
Control (ATC) Panel, the indicator will illuminate
when on.
2.Next, adjust the temperature you would like the system
to maintain by adjusting the temperature control buttons.
Once the desired temperature is displayed, the system
will achieve and automatically maintain that comfort
level.
206 UNDERSTANDING YOUR INSTRUMENT PANEL

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.

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
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.
302 MAINTAINING YOUR VEHICLE

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 sys-
tem is overheated. Do not loosen or remove the cap to
cool an overheated cooling system. Heat causes pres-
sure 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.

MAINTAINING YOUR VEHICLE 303

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).
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.
304 MAINTAINING YOUR VEHICLE

Please note that it is the owner ’s responsibility to main-
tain the proper level of protection against freezing ac-
cording 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” in Section 7 of this
supplement for the proper maintenance 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.
CAUTION!
It is recommended to have the cooling systems ser-
viced at your authorized dealer. Failure to do so could
result in poor cooling system performance and/or
vehicle damage.
Disposal Of Used Power Electronics and Battery
Thermal Management Systems Coolant
Used antifreeze is a regulated substance requiring proper
disposal. Check with your local authorities to determine
the disposal rules for your community. To prevent inges-
tion by animals or children, do not store antifreeze in
open containers or allow it to remain in puddles on the
ground. If ingested by a child, contact a physician
immediately. Clean up any ground spills immediately.

Points To Remember
If an examination of your underhood compartment
shows no evidence of cooler or hose leaks, the vehicle
may be safely driven.
•Do not overfill the coolant recovery bottles.
•Check coolant (antifreeze) freeze point in the coolant
recovery bottles. If coolant (antifreeze) needs to be
added, contents of coolant recovery bottles must also
be protected against freezing.
•If frequent coolant (antifreeze) additions are required,
or if the level in the coolant recovery bottles does not
drop when the engine cools, the cooling system should
be pressure tested for leaks.
•Maintain coolant (antifreeze) concentration at 50%
OAT coolant (antifreeze) (minimum) and distilled/
deionized water for proper corrosion protection of
your engine which contains aluminum components.
•Make sure that the coolant control systems recovery
bottles overflow hoses are not kinked or obstructed.
•Keep the front of the coolant control systems clean. If
your vehicle is equipped with air conditioning, keep
the front of the condenser clean.
