2018 FIAT 500C fuel pump

Your vehicle may also be designed to perform any of these
other functions in response to the Enhanced Accident
Response System:
• Turn off the Fuel Filter Heater, Turn off the HVAC
Blower Motor, Close the HVAC Circulation Door
• Cut off battery power to the:
• Engine
• Electric Motor (if equipped)
• Electric power steering
• Brake booster
• Electric park brake
• Automatic transmission gear selector
• Horn
• Front wiper
• Headlamp washer pump
NOTE: After an accident, remember to cycle the ignition
to the STOP (OFF/LOCK) position and remove the key
from the ignition switch to avoid draining the battery.
Carefully check the vehicle for fuel leaks in the engine compartment and on the ground near the engine compart-
ment and fuel tank before resetting the system and starting
the engine. If there are no fuel leaks or damage to the
vehicle electrical devices (e.g. headlights) after an accident,
reset the system by following the procedure described
below. If you have any doubt, contact an authorized dealer.
Enhanced Accident Response System Reset
Procedure
After the event occurs, when the system is active, a
message regarding fuel cutoff is displayed. Turn the igni-
tion switch from ignition AVV/START or MAR/ACC/
ON/RUN to ignition STOP/OFF/LOCK. Carefully check
the vehicle for fuel leaks in the engine compartment and on
the ground near the engine compartment and fuel tank
before resetting the system and starting the engine.
Depending on the nature of the event the left and right turn
signal lights, located in the instrument panel, may both be
blinking and will continue to blink. In order to move your
vehicle to the side of the road, you must follow the system
reset procedure.134 SAFETY

WARNING!• Never have any smoking materials lit in or near the
vehicle when the gas cap is removed or the tank is
being filled.
• Never add fuel when the engine is running. It may
cause the MIL to turn on and could cause a fire.
• A fire may result if gasoline is pumped into a
portable container that is inside of a vehicle. You
could be burned. Always place gas containers on the
ground while filling.
CAUTION!• Damage to the fuel system or emission control sys-
tem could result from using an improper fuel filler
cap. A poorly fitting cap could let impurities into the
fuel system. Also, a poorly fitting aftermarket cap
can cause the “Malfunction Indicator Light (MIL)”
to illuminate, due to fuel vapors escaping from the
system.
• To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling. NOTE:
• When the fuel nozzle “clicks” or shuts off, the fuel tank
is full.
• Tighten the gas cap about 1/4 turn until you hear one
click. This is an indication that the cap is properly
tightened.
• If the gas cap is not tightened properly, the MIL will
come on. Be sure the gas cap is tightened every time the
vehicle is refueled.
Loose Fuel Filler Cap Message
After fuel has been added, the vehicle diagnostic system
can determine if the fuel filler cap is possibly loose,
improperly installed, or damaged. If the system detects a
malfunction, the “gASCAP” message will display in the
odometer display. Tighten the gas cap until a  clicking 
sound is heard. This is an indication that the gas cap is
properly tightened. Push the odometer reset button to turn
the message off. If the problem persists, the message will
appear the next time the vehicle is started. This might
indicate a damaged cap. If the problem is detected twice in
a row, the system will turn on the MIL. Resolving the
problem will turn the MIL off. 6STARTING AND OPERATING 187

Indiscriminate use of fuel system cleaning agents should
be avoided. Many of these materials intended for gum and
varnish removal may contain active solvents or similar
ingredients. These can harm fuel system gasket and dia-
phragm materials.
Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline with oxygen-
ates such as ethanol.
CAUTION!DO NOT use E-85, gasoline containing methanol, or
gasoline containing more than 15% ethanol (E-15). Use
of these blends may result in starting and drivability
problems, damage critical fuel system components,
cause emissions to exceed the applicable standard,
and/or cause the Malfunction Indicator Light to illu-
minate. Please observe pump labels as they should
clearly communicate if a fuel contains greater than 15%
ethanol (E-15). Problems that result from using gasoline containing more
than 15% ethanol (E-15) or gasoline containing methanol
are not the responsibility of the manufacturer and may
void or not be covered under New Vehicle Limited War-
ranty.
Do Not Use E-85 In Non-Flex Fuel Vehicles
Non-Flex Fuel Vehicles (FFV) are compatible with gasoline
containing up to 15% ethanol (E-15). Use of gasoline with
higher ethanol content may void the New Vehicle Limited
Warranty.
If a Non-FFV vehicle is inadvertently fueled with E-85 fuel,
the engine will have some or all of these symptoms:
• Operate in a lean mode.
• OBD II “Malfunction Indicator Light” on.
• Poor engine performance.
• Poor cold start and cold drivability.
• Increased risk for fuel system component corrosion.288 TECHNICAL SPECIFICATIONS

CNG And LP Fuel System Modifications
Modifications that allow the engine to run on Compressed
Natural Gas (CNG) or Liquid Propane (LP) may result in
damage to the engine, emissions, and fuel system compo-
nents. Problems that result from running CNG or LP are
not the responsibility of the manufacturer and may void or
not be covered under the New Vehicle Limited Warranty.
MMT In Gasoline
Methylcyclopentadienyl Manganese Tricarbonyl (MMT) is
a manganese-containing metallic additive that is blended
into some gasoline to increase octane. Gasoline blended
with MMT provides no performance advantage beyond
gasoline of the same octane number without MMT. Gaso-
line blended with MMT reduces spark plug life and
reduces emissions system performance in some vehicles.
The manufacturer recommends that gasoline without
MMT be used in your vehicle. The MMT content of
gasoline may not be indicated on the gasoline pump;
therefore, you should ask your gasoline retailer whether
the gasoline contains MMT. MMT is prohibited in Federal
and California reformulated gasoline. Fuel System Cautions
CAUTION!Follow these guidelines to maintain your vehicle’s
performance:
• The use of leaded gasoline is prohibited by Federal
law. Using leaded gasoline can impair engine perfor-
mance and damage the emissions control system.
• An out-of-tune engine or certain fuel or ignition
malfunctions can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune or
malfunctioning and may require immediate service.
Contact an authorized dealer for service assistance.
• The use of fuel additives, which are now being sold
as octane enhancers, is not recommended. Most of
these products contain high concentrations of metha-
nol. Fuel system damage or vehicle performance
problems resulting from the use of such fuels or
additives is not the responsibility of the manufac-
turer and may void or not be covered under the New
Vehicle Limited Warranty. 9TECHNICAL SPECIFICATIONS 289
