2020 FIAT 500 check engine

WARNING
31)If the gearbox is faulty, contact a Fiat Dealership as soon as possible to have the system checked.
Warning light What it means
red“DUALDRIVE” ELECTRIC POWER STEERING FAILURE
When the key is turned to MAR, the warning light switches on but it should switch off after a few seconds.
If the warning light stays on, on some versions along with a dedicated message on the display, you may
not have steering assistance and the effort required to operate the steering wheel could be notably
increased; steering is, however, possible.
In this case, contact a Fiat Dealership.
If the warning light switches on while driving (on some versions, together with a dedicated message on the
display) you may not have steering assistance. Although it will still be possible to steer the vehicle, the effort
needed to operate the steering wheel could be increased: contact a Fiat Dealership as soon as possible.
IMPORTANT In some circumstances, factors independent of the electric power steering could cause the
warning light on the instrument panel to switch on. In this case, stop the car immediately (should it be in
motion), stop the engine for about 20 seconds and then restart the engine. If the warning light stays on,
contact a Fiat Dealership.
IMPORTANT After the battery is disconnected, the steering must be initialised. The warning light switches
on to indicate this. To carry out this procedure, simply turn the steering wheel all the way from one end to
the other or drive in a straight line for about a hundred metres.
redOPEN DOORS / BONNET / BOOT (versions with multifunctional display)
The warning light appears on the display, together with a dedicated message, on some versions, when one
or more doors, the tailgate or the bonnet (for versions/markets, where provided) are not properly closed.
An acoustic warning is also emitted with the doors open and the car in motion.

Warning light What it means
yellowINJECTION / EOBD SYSTEM FAILURE
Under normal conditions, the warning light comes on when the ignition key is turned to MAR, but should
go off as soon as the engine is started.
The warning light remains on or switches on while driving, on some versions together with a dedicated
message on the display, if the injection system is not working properly. In particular, if the warning light
switches on continuously, it indicates a malfunction in the supply/ignition system that could cause
excessive exhaust emissions, a possible loss of performance, poor driveability and high fuel consumption.
Under these conditions, the vehicle can continue travelling at moderate speed without demanding
excessive effort from the engine. Prolonged use of the car with the warning light on may cause damage.
Contact a Fiat Dealership as soon as possible.
If the warning light is flashing, this indicates that the catalytic converter may be damaged.
If the light flashes, come off the accelerator pedal to reduce engine revs until the warning light stops
flashing; continue the journey at moderate speed, trying to avoid driving conditions that may cause further
flashing, and get to a Fiat Dealership as soon as possible.

Warning light What it means
yellowFIAT CODE SYSTEM FAILURE
With the key in the MAR position, on some versions the warning light, or the symbol on the display, turns
on continuously, along with a dedicated message on the display, to signal a possible Fiat CODE system
failure.
If the warning light or symbol blinks on the display with engine running, it means that the vehicle is not
protected by the engine immobiliser device.
In this case, contact a Fiat Dealership as soon as possible.
yellowFUEL RESERVE - LIMITED RANGE
The warning light switches on when the ignition key is turned to MAR, but it should switch off after a few
seconds.
The warning light or the symbol switches on in the display when about 5 litres of fuel are left in the tank.
The triangle on the right side of the symbol indicates the side of the car with the fuel filler.
IMPORTANT If the warning light flashes or the symbol is constantly on, depending on the versions, there is
a fault in the system. If this is the case, go to a Fiat Dealership to have the system checked.
yellowREAR FOG LIGHT
The warning light switches on when the rear fog light is activated.
yellowABS FAILURE
The warning light switches on when the ignition key is turned to MAR, but it should switch off after a few
seconds.
The warning light comes on, on some versions along with a message on the display, when the system is
inefficient or not available. In this case the braking system maintains its efficiency unaltered but without the
advantage of the ABS system.
Drive carefully and contact a Fiat Dealership as soon as possible.

Symbol What it means
yellowPASSENGER AIRBAG/SIDE BAGS DEACTIVATED
The warning light indicates the passenger airbag protection status. If the warning light is off, passenger's
airbag protection is active: to deactivate it, use the Setup Menu (in this case the LED lights up). When the
engine is started (ignition key turned to MAR position), the warning light turns on for about 8 seconds,
provided that at least 5 seconds have elapsed from when it was switched off. If not, contact a Fiat
Dealership. If the engine is switched off/on again in less than 5 seconds the warning light may remain off. In
this case, to check correct warning light operation, switch the engine off, wait for at least 5 seconds and
switch the engine on again. The warning light may light up with various intensity levels depending on the
vehicle conditions. The intensity may also vary during the same key cycle.

WARNING
47)If the warning light switches on, the degraded engine oil must be changed as soon as possible, and never more than 500 km from the
first time that the warning light switches on. Failure to observe the above may result in severe damage to the engine and invalidate the
warranty. The activation of this warning light is not related to the amount of oil in the engine. Therefore, never top up with oil when the warning
light starts flashing.
48)If the warning light
(or the amber warning light, for versions/markets, where provided) switches on, the degraded engine oil
must be changed as soon as possible, and never more than 500 km from the first time that the warning light switches on. Failure to observe
the above may result in severe damage to the engine and invalidate the warranty. The activation of this warning light is not related to the
amount of oil in the engine. Therefore, never top up with oil when the warning light starts flashing.
63

Under special conditions (e.g. car
loaded asymmetrically on one side,
damaged or worn tyre, fitting the
space-saver spare wheel, fitting snow
chains, fitting different tyres on the
axles) the system may give false
warnings or be temporarily deactivated.
If the system is temporarily deactivated
the
warning light flashes for about
75 seconds and then is continuously
on; at the same time, the display shows
a warning message.
This warning is displayed also after the
engine has been switched off and
then on again if the correct operating
conditions are not restored.
WARNING
77)If the system signals a pressure
decrease on one or more tyres, it
is recommended to always check the
pressure on all four tyres.
78)The iTPMS does not relieve the driver
from the obligation to check the tyre
pressure every month; it is not to
be considered a system to replace
maintenance or a safety system.
79)Tyre pressure must be checked with
tyres cold. Should it become necessary for
whatever reason to check pressure with
warm tyres, do not reduce pressure even
though it is higher than the prescribed
value, but repeat the check when tyres are
cold.80)The iTPMS cannot indicate sudden tyre
pressure drops (for example when a tyre
bursts). In this case, stop the vehicle,
braking with caution and avoiding abrupt
steering.
81)The system only warns that the tyre
pressure is low: it is not able to inflate
them.
82)Insufficient tyre inflation increases fuel
consumption, reduces the tread duration
and may affect the capacity to drive safely.
OCCUPANT
PROTECTION
SYSTEMS
some of the most important safety
equipment of the vehicle comprise the
following protection systems:
seat belts;
SBR (Seat Belt Reminder) system;
head restraints;
child restraint systems;
Front airbags and side bags.
Read the information given the
following pages with the utmost care. It
is of fundamental importance that the
protection systems are used in the
correct way to guarantee the maximum
possible safety level for the driver and
the passengers.
For the description of the head restraint
adjustment see the "Head restraints"
paragraph in the "Knowing your
vehicle" chapter.
73

106)In some versions, in the event of a
LEDfailure (located on the dashboard
panel), thewarning light on the
instrument panel turns on and the
passenger side airbags are deactivated.
107)The
warning light indicates the
passenger side airbag protection status. If
the warning light is off, passenger side
protection is active: to deactivate it, use the
Setup Menu (in this case the LED lights
up). When the car is started (ignition key
turned to MAR position), the warning light
turns on for about 8 seconds, provided
that at least 5 seconds have elapsed from
when it was switched off. If not, contact
a Fiat Dealership. If the engine is switched
off/on again in less than 5 seconds the
warning light may remain off. In this case,
to check correct warning light operation,
switch the engine off, wait for at least 5
seconds and switch the engine on again.
The warning light may light up with various
intensity levels depending on the vehicle
conditions. The intensity may also vary
during the same key cycle. When the
ignition key is turned to MAR, the
warning light switches for few seconds,
then if the passenger airbag protection is
active it should switch off.
108)If a child must be carried on the front
seat in a rearward facing child restraint
system, it is compulsory to deactivate the
passenger side front airbag, making sure
that it is deactivated by checking the
dedicated warning light on the instrument
panel. Move the passenger's seat as far
back as possible to avoid contact between
the child restraint system and the
dashboard.109)Malfunction of the
warning light is
indicated by the activation of an airbag
failure symbol and a dedicated message
on the instrument panel display (or, for
versions where provided, by the activation
of a blinking generic failure warning light). In
this case, the
warning light may not
indicate failures in the restraint systems.
Contact a Fiat Dealership immediately
to have the system checked.
110)Do not use seatcovers on front seats
featuring side airbags.
111)Do not travel carrying objects in your
lap, in front of your chest or between
your lips (pipe, pencils, etc.): they could
cause severe injury if the airbag is
deployed.
112)If the car has been stolen or in the
case of attempt to steal it, if it has been
subjected to vandalism or floods, have the
airbag system checked by a Fiat
Dealership.113)The airbags may also be deployed
when the car is not moving, if the key is in
the ignition and turned to MAR-ON or
when the engine is off, if the car is hit by
another moving vehicle. Therefore, even if
the vehicle is stationary, when an active
front passenger airbag is fitted, DO NOT
install rearward facing child restraint
systems on the front passenger seat.
Deployment of the airbag following an
impact could cause fatal injuries to the
child. Therefore, always deactivate the
passenger side airbag when a rearward
facing child restraint system is installed on
the front passenger seat. The front
passenger seat must also be positioned
back as far as possible in order to prevent
the child restraint system from coming
into contact with the dashboard.
Immediately reactivate the passenger
airbag as soon as the child restraint system
has been removed. Also remember that, if
the key is turned to STOP, none of the
safety devices (airbags or pretensioners)
will be deployed in the event of collision.
Non-deployment in such cases does
not indicate a system malfunction.
114)When the ignition key is turned to
MAR, the
warning light switches for few
seconds, then if the passenger airbag
protection is active it should switch off.
115)Do not wash the seats with water or
pressurised steam (wash by hand or at
automatic seat washing stations).
116)The airbag deployment threshold is
higher than that of the pretensioners.
For collisions in the range between the two
thresholds, it is normal for only the
pretensioners to be activated.
