Battery FIAT 500E 2017 2.G Service Manual

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.

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.
Maintenance-Free Battery 12 Volt
Your vehicle is equipped with a maintenance-free 12
Volt battery. You will never have to add water, nor is
periodic maintenance required.
WARNING!
• Battery fluid is a corrosive acid solution and can
burn or even blind you. Do not allow battery
fluid to contact your eyes, skin, or clothing. Do
not lean over a battery when attaching clamps. If
acid splashes in eyes or on skin, flush the area
immediately with large amounts of water. Refer
to “Jump-Starting Procedures” in “What To Do In
Emergencies” for further information.
• Battery gas is flammable and explosive. Keep
flame or sparks away from the battery. Do not use
a booster battery or any other booster source with
an output greater than 12 Volts. Do not allow
cable clamps to touch each other.
• Battery posts, terminals, and related accessories
contain lead and lead compounds. Wash hands
after handling.
• The battery in this vehicle has a vent hose that
should not be disconnected and should only be
replaced with a battery of the same type (vented).

MAINTAINING YOUR VEHICLE 247

CAUTION!
•It is essential when replacing the cables on the
battery that the positive cable is attached to the
positive post and the negative cable is attached to
the negative post. Battery posts are marked posi-
tive (+) and negative (-) and are identified on the
battery case. Cable clamps should be tight on the
terminal posts and free of corrosion.
• If a 12 Volt Low Voltage Battery System “fast
charger” is used while the battery is in the ve-
hicle, disconnect both vehicle battery cables be-
fore connecting the charger to the battery. Do not
use a “fast charger” to provide starting voltage.
Air Conditioner Maintenance
For best possible performance, your air conditioner
should be checked and serviced by an authorized dealer
at the start of each warm season. This service should
include cleaning of the condenser fins and air condi-
tioning performance tests.
CAUTION!
Do not use chemical flushes in your air condition-
ing system as the chemicals can damage your air
conditioning components. Such damage is not cov-
ered by the New Vehicle Limited Warranty.
WARNING!
• Use only refrigerants and compressor lubricants
approved by the manufacturer for your air condi-
tioning system. Some unapproved refrigerants are
flammable and can explode, injuring you. Other
unapproved refrigerants or lubricants can cause
the system to fail, requiring costly repairs. Refer
to Warranty Information Book, located on the
DVD, for further warranty information.
• The air conditioning system contains refrigerant
under high pressure. To avoid risk of personal
injury or damage to the system, adding refriger-
ant or any repair requiring lines to be discon-
nected should be done by an experienced techni-
cian.

VEHICLE STORAGE
The preferred way of storing your vehicle for a long
period of time is to leave it attached to a Level 1 or Level
2 charger. The vehicle has a wake-up feature that will
wake the system every 3 weeks and do a maintenance
charge on the 12 Volt battery and also top off the high
voltage battery if necessary. Anytime you store your vehicle, or keep it out of service
(e.g., vacation) for two weeks or more, run the air
conditioning system at idle for about five minutes in the
fresh air and high blower setting. This will ensure
adequate system lubrication to minimize the possibility
of compressor damage when the air conditioning sys-
tem is started again.
