2018 FIAT 500E coolant

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.
70 GETTING TO KNOW YOUR VEHICLE

WARNING!(Continued)
•ALWAYS make sure objects cannot fall or slide into
the driver ’s side floor area when the vehicle is
moving. Objects can become trapped under accelera-
tor, brake, or clutch pedals and could cause a loss of
vehicle control.
• NEVER place any objects under the floor mat (e.g.,
towels, keys, etc.). These objects could change the
position of the floor mat and may cause interference
with the accelerator, brake, or clutch pedals.
• If the vehicle carpet has been removed and re-
installed, always properly attach carpet to the floor
and check the floor mat fasteners are secure to the
vehicle carpet. Fully depress each pedal to check for
interference with the accelerator, brake, or clutch
pedals then re-install the floor mats.
• It is recommended to only use mild soap and water
to clean your floor mats. After cleaning, always check
your floor mat has been properly installed and is
secured to your vehicle using the floor mat fasteners
by lightly pulling mat.
Periodic Safety Checks You Should Make Outside
The Vehicle
Tires
Examine tires for excessive tread wear and uneven wear
patterns. Check for stones, nails, glass, or other objects
lodged in the tread or sidewall. Inspect the tread for cuts
and cracks. Inspect sidewalls for cuts, cracks, and bulges.
Check the wheel nuts for tightness. Check the tires (includ-
ing spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under vehicle after overnight parking for
coolant or other fluid leaks. If fluid leaks are suspected, the
cause should be located and corrected immediately.

SAFETY 151

Shallow Standing Water
Although your vehicle is capable of driving through shal-
low standing water, consider the following Caution and
Warning before doing so.
CAUTION!
•Always check the depth of the standing water before
driving through it. Never drive through standing
water that is deeper than the bottom of the tire rims
mounted on the vehicle.
• Determine the condition of the road or the path that
is under water and if there are any obstacles in the
way before driving through the standing water.
• Do not exceed 5 mph (8 km/h) when driving through
standing water. This will minimize wave effects.
• Driving through standing water may cause damage
to your vehicle’s drivetrain components. Always in-
spect your vehicle’s fluids (i.e., transmission, coolant,
etc.) for signs of contamination (i.e., fluid that is
milky or foamy in appearance) after driving through
standing water. Do not continue to operate the ve-
hicle if any fluid appears contaminated, as this may
(Continued)
CAUTION! (Continued)
result in further damage. Such damage is not covered
by the New Vehicle Limited Warranty.
• Driving through standing water limits your vehicle’s
traction capabilities. Do not exceed 5 mph (8 km/h)
when driving through standing water.
• Driving through standing water limits your vehicle’s
braking capabilities, which increases stopping dis-
tances. Therefore, after driving through standing
water, drive slowly and lightly press on the brake
pedal several times to dry the brakes.
• Failure to follow these warnings may result in inju-
ries that are serious or fatal to you, your passengers,
and others around you.
EXTENDING YOUR DRIVING RANGE PER CHARGE
The drive system and cabin temperature management
features use the most energy from the high voltage battery.
Reducing energy draw from these features are the easiest
and most effective way to extend driving range.
The 500e uses high voltage components to heat and cool
the cabin, so when using automatic climate control, con-
sider setting temperatures a few degrees higher or lower
during hot and cold days. If your 500e has been soaking in

TIRE SERVICE KIT — IF EQUIPPED
Small punctures up to 1/4 inch (6 mm) in the tire tread can
be sealed with Tire Service Kit. Foreign objects (e.g., screws
or nails) should not be removed from the tire. Tire Service
Kit can be used in outside temperatures down to approxi-
mately -4°F (-20°C).
This kit will provide a temporary tire seal, allowing you to
drive your vehicle up to 100 miles (160 km) with a
maximum speed of 50 mph (80 km/h).

UNDERHOOD COMPARTMENT
Adding Washer Fluid
The windshield washer fluid reservoir is located in the
underhood compartment, and the fluid level should be
checked at regular intervals. Fill the reservoir with wind-
shield washer solvent (not coolant/ antifreeze). Refer to
“Underhood Compartment” in this section for further
information.
WARNING!
Commercially available windshield washer solvents
are flammable. They could ignite and burn you. Care
must be exercised when filling or working around the
washer solution.
