cooling FIAT 500E 2017 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 ve-
hicle is placed into PARK. This will prevent any un-
wanted 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 uti-
lizes a humidity sensor, cabin sensor, and ambient
temperature sensor to choose operation mode and
control cabin comfort. These components allow the
controller to operate the HVAC system in a very effi-
cient 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 ve-
hicle 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 Steer-
ing (EPS) system. The power steering system requires
no maintenance and operates without the use of power
steering fluid.
12 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

NOTE:
•If fog or mist appears on the windshield or side glass,
select Defrost mode and increase blower speed if
needed.
• If your air conditioning performance seems lower
than expected, check the front of the A/C condenser
(located in front of the radiator), for an accumulation
of dirt or insects. Clean with a gentle water spray
from the front of the radiator and through the
condenser.
Recirculation
When outside air contains smoke, odors, or high hu-
midity, or if rapid cooling is desired, you may wish to
recirculate interior air by pushing the Recirculation
control button. The recirculation indicator will illumi-
nate when this button is selected. Push the button a
second time to turn off the Recirculation mode 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 (button on the touchscreen
greyed out) 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 automatically
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 Temperature Control (ATC) — If
Equipped
Automatic Operation
1. Push the AUTO button on the faceplate.
2. Next, adjust the temperature you would like the system to maintain by adjusting the driver and
passenger temperature control buttons. 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, itis 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
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 feature.
To provide you with maximum comfort in the Auto-
matic 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
This system offers a full complement of manual over-
ride 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
presence of fog, mist or ice on the windshield. DE-
FROST 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 condi-
tions.
Summer Operation
The engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corro-
sion protection and to protect against engine overheat-
ing. OAT coolant (conforming to MS.90032) is recom-
mended. Refer to “Maintenance Procedures” in
“Maintaining Your Vehicle” for proper coolant selec-
tion.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is func-
tioning properly and the proper amount, type, and
concentration of coolant is used. Refer to “Maintenance

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,
cracking, 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 PRES-
SURE 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.

MAINTAINING YOUR VEHICLE 243

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.
(Continued)
WARNING! (Continued)
•Do not use a pressure cap other than the one
specified for your vehicle. Personal injury or
vehicle 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 speci-
fied Organic Additive Technology (OAT) coolant
(antifreeze), 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 Technology (HOAT) coolant (anti-
freeze). If a non-OAT coolant (antifreeze) is intro-
duced into the cooling system in an emergency, it
should be replaced with the specified coolant
(antifreeze) as soon as possible.
(Continued)
244 MAINTAINING YOUR VEHICLE

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 Or-
ganic 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
deionized water when mixing the water and coolant
(antifreeze) solution. The use of lower quality water
will reduce the amount of corrosion protection in the
cooling systems.
Please note that it is the owner ’s 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.

MAINTAINING YOUR VEHICLE 245

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 consid-
erable 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
serviced 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 ingestion by animals or children, do not store
antifreeze in open containers or allow it to remain inpuddles on the ground. If ingested by a child, contact a
physician immediately. Clean up any ground spills
immediately.
Points To Remember
WARNING!
•
Turn vehicle OFF and disconnect the fan motor
lead before working near the radiator cooling fan.
• You or others can be badly burned by hot engine
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 open a cooling system
pressure cap when the radiator or coolant bottle is
hot.
• Keep hands, tools, clothing, and jewelry away
from the radiator cooling fan when the hood is
raised. The fan may start without warning,
whether the ignition is on or off.
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.
246 MAINTAINING YOUR VEHICLE

•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 re-
quired, 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.
