2018 FIAT 500C engine overheat

3. When the system is set up for your comfort level, it is
not necessary to change the settings. You 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 fea-
ture.
To provide you with maximum comfort in the Automatic
mode during cold start-ups, the blower fan remains on low
until the engine 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 engine cooling system must be protected with a
high-quality antifreeze coolant to provide proper corrosion
protection and to protect against engine overheating. OAT
coolant (conforming to MS.90032) is recommended.
Winter Operation
To ensure the best possible heater and defroster perfor-
mance, make sure the engine 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.54 GETTING TO KNOW YOUR VEHICLE

Instrument Cluster Descriptions
1. Tachometer
• This gauge measures engine revolutions per minute
(RPM x 1000). Before the pointer reaches the red area,
ease up on the accelerator to prevent engine damage.
2. Temperature Gauge
• The temperature gauge shows engine coolant tem-
perature. Any reading within the normal range indi-
cates that the engine cooling system is operating
satisfactorily.
• The digital gauge will likely indicate a higher tempera-
ture when driving in hot weather, or up mountain
grades. It should not be allowed to exceed the upper
limits of the normal operating range.
WARNING!• Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge reads
“H” pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
drops back into the normal range. If the pointer (Continued) WARNING! (Continued)remains on the “H,” turn the engine off immediately
and call an authorized dealer for service.
• A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer
for service if your vehicle overheats. If you decide to
look under the hood yourself, see “Servicing And
Maintenance.” Follow the warnings under the Cool-
ing System Pressure Cap paragraph.
3. Speedometer
• Indicates vehicle speed.
4. Fuel Gauge
• The digital display shows the amount of fuel in the
tank.
• The switching on of the digital warning light indicates
that 1 – 1.3 gallons of fuel are left in the tank; in this
situation, refuel as soon as possible.
• Do not travel with the fuel tank almost empty; any
gaps in fuel delivery could damage the catalytic con-
verter.78 GETTING TO KNOW YOUR INSTRUMENT PANEL

— Door Open Warning Light
This indicator will illuminate when one or more door(s) are
not fully closed.
NOTE: If the vehicle is moving and a door is opened, there
will also be a single chime.
— Electric Power Steering Fault Warning Light
This warning light will turn on when there’s a fault with the
EPS (Electric Power Steering) system. Refer to “Power Steer-
ing” in “Starting And Operating” for further information.
WARNING!Continued operation with reduced assist could pose a
safety risk to yourself and others. Service should be
obtained as soon as possible.
— Electronic Throttle Control (ETC) Warning
Light
This warning light will illuminate to indicate a problem
with the Electronic Throttle Control (ETC) system. If a
problem is detected while the vehicle is running, the light
will either stay on or flash depending on the nature of the problem. Cycle the ignition when the vehicle is safely and
completely stopped and the transmission is placed in the
PARK position. The light should turn off. If the light
remains on with the vehicle running, your vehicle will
usually be drivable; however, see an authorized dealer for
service as soon as possible.
NOTE: This light may turn on if the accelerator and brake
pedals are pressed at the same time.
If the light continues to flash when the vehicle is running,
immediate service is required and you may experience
reduced performance, an elevated/rough idle, or engine
stall and your vehicle may require towing. The light will
come on when the ignition is placed in the ON/RUN or
ACC/ON/RUN position and remain on briefly as a bulb
check. If the light does not come on during starting, have
the system checked by an authorized dealer.
— Engine Coolant Temperature Warning Light
This light warns of an overheated engine condition. If the
engine coolant temperature is too high, this indicator will
illuminate and a single chime will sound.86 GETTING TO KNOW YOUR INSTRUMENT PANEL

If the light turns on while driving, safely pull over and stop
the vehicle. If the A/C system is on, turn it off. Also, shift
the transmission into NEUTRAL and idle the vehicle. If the
temperature reading does not return to normal, turn the
engine off immediately and call for service. Refer to “If
Your Engine Overheats” in “In Case Of Emergency” for
further information.
— Hood Open Warning Light — If Equipped
This warning light will illuminate when the hood is left
open and not fully closed.
— Liftgate Open Warning Light
This indicator will illuminate when the liftgate is open/
ajar/not fully closed.
— Oil Pressure Warning Light
This warning light will illuminate to indicate low engine
oil pressure. If the light turns on while driving, stop the
vehicle, shut off the engine as soon as possible, and contact
an authorized dealer. A chime will sound when this light
turns on. Do not operate the vehicle until the cause is corrected. This
light does not indicate how much oil is in the engine. The
engine oil level must be checked under the hood.
— Seat Belt Reminder Warning Light
This warning light indicates when the driver or passenger
seat belt is unbuckled. When the ignition is first placed in
the ON/RUN or ACC/ON/RUN position and if the
driver ’s seat belt is unbuckled, a chime will sound and the
light will turn on. When driving, if the driver or front
passenger seat belt remains unbuckled, the Seat Belt Re-
minder Light will flash or remain on continuously and a
chime will sound.
Refer to “Occupant Restraint Systems” in “Safety” for
further information.
— Transmission Fault Warning Light
This light will illuminate (together with a message in the
instrument cluster display and a buzzer) to indicate a
transmission fault. Contact an authorized dealer if the
message remains after restarting the engine. 4GETTING TO KNOW YOUR INSTRUMENT PANEL 87

WARNING!Do not coast in NEUTRAL and never turn off the
ignition to coast down a hill. These are unsafe practices
that limit your response to changing traffic or road
conditions. You might lose control of the vehicle and
have a collision.
CAUTION!Towing the vehicle, coasting, or driving for any other
reason with the transmission in NEUTRAL can cause
severe transmission damage. Refer to “Recreational
Towing” in “Starting And Operating” and “Towing A
Disabled Vehicle” in “In Case Of Emergency” for
further information.
DRIVE (D)
This range should be used for most city and highway
driving. It provides the smoothest upshifts and downshifts,
and the best fuel economy. The transmission automatically
upshifts through all forward gears. The DRIVE position
provides optimum driving characteristics under all normal
operating conditions. When frequent transmission shifting occurs (such as when
operating the vehicle under heavy loading conditions, in
hilly terrain, or traveling into strong head winds), use the
AutoStick shift control (refer to AutoStick in this section for
further information) to select a lower gear. Under these
conditions, using a lower gear will improve performance
and extend transmission life by reducing excessive shifting
and heat buildup.
If the transmission temperature exceeds normal operating
limits, the transmission controller will expand the range of
torque converter clutch engagement. This is done to pre-
vent transmission damage due to overheating.
During cold temperatures, transmission operation may be
modified depending on engine coolant temperature. Nor-
mal operation will resume once the engine temperature has
risen to a suitable level.
Instrument Cluster Messages
Dedicated messages will be displayed in the instrument
cluster to alert the driver when certain unusual conditions
occur. 6STARTING AND OPERATING 173

NOTE: In AutoStick mode, the transmission will only shift
up or down when the driver moves the gear selector
rearward (+) or forward (-), except as described below.
• The transmission will automatically upshift when nec-
essary to prevent engine over-speed.
• The transmission will automatically downshift as the
vehicle slows (to prevent engine lugging) and will
display the current gear.
• The transmission will automatically downshift to first
gear when coming to a stop. After a stop, the driver
should manually upshift (+) the transmission as the
vehicle is accelerated.
• You can start out (from a stop) in first, second, or third
gear. Starting out in second or third gear can be helpful
in snow or icy conditions. To select second or third gear
after the vehicle is brought to a stop, tap the gear selector
rearward (+) once or twice.
• The system will ignore shift commands that would
cause engine lugging or overspeed. An audible beep will
sound if an inappropriate gear is requested. • Avoid using speed control when AutoStick is engaged
because the transmission will not shift automatically.
• Transmission shifting will be more noticeable when
AutoStick is enabled.
• The system may revert to automatic shift mode if a fault
or overheat condition is detected.
To disengage AutoStick mode, return the gear selector to
the DRIVE position. You can shift in or out of the AutoStick
position at any time without taking your foot off the
accelerator pedal.
WARNING!Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their grip
and the vehicle could skid, causing a collision or
personal injury. 6STARTING AND OPERATING 175

IF YOUR ENGINE OVERHEATS
In any of the following situations, you can reduce the
potential for overheating by taking the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, place the transmission in
NEUTRAL, but do not increase engine idle speed.
NOTE: There are steps that you can take to slow down an
impending overheat condition:
• If your air conditioner (A/C) is on, turn it off. The A/C
system adds heat to the engine cooling system and
turning the A/C off can help remove this heat.
• You can also turn the temperature control to maximum
heat, the mode control to floor and the blower control to
high. This allows the heater core to act as a supplement
to the radiator and aids in removing heat from the
engine cooling system.
WARNING!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 (Continued) WARNING! (Continued)open the hood until the radiator has had time to cool.
Never try to open a cooling system pressure cap when
the radiator or coolant bottle is hot.
CAUTION!Driving with a hot cooling system could damage your
vehicle. If the pointer rises to the H (red) mark, the
instrument cluster will sound a chime. When safe, pull
over and stop the vehicle with the engine at idle. Turn
off the air conditioning and wait until the pointer
drops back into the normal range. If the pointer
remains on the H (red) mark for more than a minute,
turn the engine off immediately and call for service.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand or snow, it can
often be moved using a rocking motion. Turn the steering
wheel right and left to clear the area around the front
wheels. Then shift back and forth between DRIVE and
REVERSE (with automatic transmission) or SECOND224 IN CASE OF EMERGENCY
