check engine light FIAT 500X 2017 Owner handbook (in English)

READ THIS CAREFULLY
REFUELLINGPetrol engines: only refuel with unleaded petrol with octane rating (RON) not less than 95 in compliance with the European specification
EN228. Do not use petrol containing methanol or ethanol E85. Using these mixtures may cause misfiring and driving issues, as well as damage
fundamental components of the supply system.
For further details on the use of the correct fuel see the "Refuelling the vehicle" paragraph in the "Starting and driving" chapter.
Diesel engines: refuel only with diesel fuel conforming to the European specification EN590. The use of other products or mixtures may
damage the engine beyond repair and consequently invalidate the warranty, due to the damage caused.
For further details on the use of the correct fuel see the "Refuelling the vehicle" paragraph in the "Starting and driving" chapter.
STARTING THE ENGINE
Versions with manual gearbox (petrol engines): make sure that the handbrake is engaged; set the gear lever to neutral, fully depress the
clutch pedal without pressing the accelerator, then turn the ignition key to AVV or press the ignition device button; release the key or the button
as soon as the engine has started.
Versions with manual gearbox (diesel engines): make sure that the handbrake is engaged; set the gear lever to neutral, fully depress the
clutch pedal without pressing the accelerator, then turn the ignition key to MAR and wait for the
warning light to switch off. Bring the ignition
key to AVV or press the ignition device button; release the key or the button as soon as the engine has started.
Versions with automatic transmission: make sure that the handbrake is engaged and that the gear lever is in P (Parking) or N (Neutral),
depress the brake pedal, without pressing the accelerator pedal, then turn the ignition key to AVV or press the ignition device button; release
the key or the button as soon as the engine has started.
PARKING ON FLAMMABLE MATERIAL
The catalytic converter develops high temperatures during operation. Do not park the vehicle on grass, dry leaves, pine needles or other
flammable material: fire hazard.
RESPECTING THE ENVIRONMENT
The vehicle is fitted with a system that carries out a continuous diagnosis of the emission-related components in order to help protect the
environment.
ELECTRICAL ACCESSORIES
If, after buying the vehicle, you decide to add electrical accessories (with the risk of gradually draining the battery), contact a Fiat Dealership.
They can calculate the overall electrical requirement and check that the vehicle's electric system can support the required load.
SCHEDULED SERVICING
Correct maintenance of the vehicle is essential for ensuring that it maintains its performance and its safety features, its environmental
friendliness and low running costs unchanged in time.

if 30 minutes pass with the vehicle
stationary (versions with manual
gearbox) or with the gear lever at P
(Park) (versions with automatic
transmission) and the engine off, the
ignition device will automatically move
to the STOP position.
NOTE With engine started, it is possible
to go away from the vehicle taking the
electronic key with you. The engine will
still be running. The vehicle will indicate
the absence of the key on board when
the door is closed.
For more information on the engine
start-up, see the description in the
"Starting the engine" paragraph, in the
"Starting and driving" chapter.

STEERING LOCK
Activation
Versions with key without remote
control: with the device at STOP,
remove the key and turn the steering
wheel until it locks.
IMPORTANT If the ignition key has been
moved from the MAR to the STOP
position, the steering lock cannot
engage until the key is removed from
the ignition device.
Versions with electronic key: the
steering lock engages when the driver
door is opened, with the ignition devicebutton at STOP and speed below
3 km/h.
Deactivation
Versions with key without remote
control: slightly moving the steering
wheel, turn the key to the MAR
position.
Versions with electronic key: the
steering lock disengages when the
ignition device is pressed and the
electronic key is recognised.

WARNING
2)If the ignition device has been tampered
with (e.g. an attempted theft), have it
checked by a Fiat Dealership before driving
again.
3)Always take the key with you when you
leave your vehicle to prevent someone
from accidentally operating the controls.
Remember to engage the electric parking
brake. Never leave children unattended in
the vehicle.
4)It is absolutely forbidden to carry out any
after-market operation involving steering
system or steering column modifications
(e.g. installation of anti-theft device) that
could adversely affect performance,
invalidate the warranty, cause serious
safety problems and also result in the car
not meeting type-approval requirements.5)Never extract the mechanical key while
the vehicle is moving. The steering wheel
will automatically lock as soon as it is
turned. This holds true for cars being
towed as well.
6)Before exiting the vehicle, ALWAYS
engage the parking brake, steer the
wheels, engage the first gear if uphill and
the reverse if downhill. On versions with
automatic transmission, bring the gear
lever to P (Park) and press the ignition
device to bring it to STOP. If the vehicle is
parked on a steep slope, chock the wheels
with wedges or stones. When leaving the
car, always lock all the doors by pressing
the dedicated button on the handle (see
"Keyless Entry" in the paragraph "Doors").
7)For versions equipped with the Full
Keyless System, do not leave the
electronic key inside or near the car or in a
place accessible to children. Do not leave
the vehicle with the ignition device in MAR
position. A child could activate the electric
window winders, other controls or even
start the vehicle.

WARNING LIGHTS AND MESSAGES
IMPORTANT The warning light switches on in the instrument panel together with a dedicated message and/or acoustic signal
when applicable. These indications are indicative and precautionary and as such must not be considered as exhaustive and/or
alternative to the information contained in the Owner Handbook, which you are advised to read carefully in all cases. Always
refer to the information in this chapter in the event of a failure indication.
IMPORTANT Failure indications displayed are divided into two categories: serious and less serious failures. Serious failures are
indicated by a repeated and prolonged warning "cycle". Less serious failures are indicated by a warning "cycle" with a shorter
duration. The display cycle of both categories can be interrupted. The instrument panel warning light will stay on until the cause
of the failure is eliminated.
Warning light What it means
INSUFFICIENT BRAKE FLUID / ELECTRIC PARKING BRAKE ON
Low brake fluid level
The warning light switches on when the brake fluid in the reservoir falls below the minimum level, possibly
due to a leak in the circuit. Restore the brake fluid level, then check that the warning light has switched
off. If the warning light stays on, contact a Fiat Dealership.
Electric parking brake on
The warning light switches on when the electric parking brake is engaged. Release the electric parking
brake, then check that the warning light has switched off. If the warning light stays on, contact a Fiat
Dealership.
EBD FAILURE
The simultaneous switching on of the
(red) and(amber) warning lights with the engine on
indicates either a failure of the EBD system or that the system is not available. In this case, the rear
wheels may suddenly lock and the vehicle may swerve when braking sharply.
Drive very carefully to the nearest Fiat Dealership to have the system inspected immediately.
49

Warning light What it means
ENGINE COOLANT TEMPERATURE TOO HIGH
The warning light (or the icon on the display on some versions) switches on when the engine is
overheated.
When driving normally: stop the vehicle, switch off the engine and check that the water level in the
reservoir is not below the MIN mark. If it is, wait for the engine to cool down, then slowly and carefully
open the cap, top up with coolant and check that the level is between the MIN and MAX marks on the
reservoir. Also check visually for any fluid leaks. If, when restarting, the warning light switches on (or the
icon is displayed) again, contact a Fiat Dealership.
If the vehicle is used under demanding conditions(e.g. in high-performance driving): slow down
and, if the warning light stays on, stop the vehicle. Stop for two or three minutes with the engine running
and slightly accelerated to facilitate better coolant circulation, then turn the engine off. Check that the
coolant level is correct as described above.
IMPORTANT Over demanding routes, it is advisable to keep the engine running and slightly accelerated
for a few minutes before turning it off.
POWER STEERING FAILURE
This warning light (or symbol in the display) switches on when the ignition device is brought to MAR, but it
should switch off after a few seconds. If the warning light (or symbol on the display) remains on, you
could not have steering assistance and the effort required to operate the steering wheel could be
increased; steering is, however, possible. On some versions, the display shows the dedicated message.
Contact a Fiat Dealership as soon as possible.
51

Warning light What it means
INJECTION/EOBD SYSTEM FAILURE
In normal conditions, when the ignition device is brought to MAR, the warning light switches on, but it
should switch off as soon as the engine is started. The operation of the warning light may be checked by
the traffic police using specific devices. Comply with the laws and regulations of the country where you
are driving.
13)
Injection system failure
If the warning light remains on, or it switches on whilst driving, the injection system is not working
properly. The warning light on constantly signals a malfunction in the supply/ignition system which could
cause high exhaust emissions, a possible loss of performance, poor driveability and high consumption.
On some versions, the display shows the dedicated message. The warning light switches off if the
malfunction disappears, but it is still stored by the system. Under these conditions, the vehicle can
continue travelling at moderate speed but without demanding excessive effort from the engine or high
speed. Prolonged use of the vehicle with the warning light on may cause damage. Contact a Fiat
Dealership as soon as possible.
Catalytic converter damaged
If the warning light flashes, it means that the catalytic converter may be damaged. Release the
accelerator pedal to lower the speed of the engine until the warning light stops flashing. Continue the
journey at moderate speed, trying to avoid driving conditions that may cause further flashing and contact
a Fiat Dealership as soon as possible.
54
KNOWING THE INSTRUMENT PANEL

WARNING
28)If, when the ignition device is turned to MAR, thewarning light does not switch on or stays on whilst driving, a failure may have
occurred in the restraint systems. In this case the airbags or pretensioners may not be deployed in an impact or, in a lower number of cases,
they may be deployed accidentally. Before continuing, contact a Fiat Dealership immediately to have the system checked.
29)The fault of the
warning light is signalled by the switching on of theicon on the instrument panel. In this case, the warning light may
not indicate any faults with the restraint systems. Before continuing, contact a Fiat Dealership immediately to have the system checked.
30)If a failure is present with sharp braking, the rear wheels may lock and the vehicle may swerve.
IMPORTANT
13)If, turning the ignition device to MAR, thewarning light does not turn on or if it turns on steadily or flashing when travelling (on some
versions together with the message on the display), contact a Fiat Dealership as soon as possible.
14)If the warning light (or the icon on the display) flashes whilst driving, contact a Fiat Dealership.
15)If the symbol switches on when driving, stop the engine immediately and contact a Fiat Dealership.
16)Driving the vehicle with this symbol on may severely damage the gearbox, with resulting breakage. The oil may also overheat: contact with
hot engine or with exhaust components at high temperature could cause fires.
17)The presence of water in the fuel system circuit may cause severe damage to the injection system and irregular engine operation. If the
symbol is displayed contact a Fiat Dealership as soon as possible to bleed the system. If the above indications come on immediately after
refuelling, water has probably been poured into the tank: switch the engine off immediately and contact a Fiat Dealership.
18)Vehicle travel speed should always be adapted to the traffic and weather conditions, and must always comply with traffic regulations. The
engine can be stopped even if the DPF warning light is on: however, repeated interruptions of the regeneration process could cause
premature deterioration of the engine oil. For this reason it is always advisable to wait for the symbol to go off before turning off the engine,
following the instructions above. Do not complete the DPF regeneration process when the vehicle is stopped.
19)If the
warning light comes on, the exhausted engine oil should be changed as soon as possible, never drive more than 500 km from
the first switching-on of this warning light. Failure to observe the above may result in severe damage to the engine and invalidate the warranty.
Remember that when this warning light comes on, it does not mean that the level of engine oil is low, so if it flashes you do not need to top up
the engine oil.
20)If the symbol flashes when driving, contact a Fiat Dealership.
69

it is correctly activated via the
Uconnect™system;
the ignition device is at MAR;
the vehicle speed is between 7 and
200 km/h;
the front seat belts are fastened.
Changing the system sensitivity
The sensitivity of the system can be
changed through theUconnect™
system menu, choosing from one of the
following three options: "Near", "Med"
or "Far". See the description in the
Uconnect™supplement for how to
change the settings.
The pre-set option is "Med". With this
setting, the system warns the driver of a
possible collision with the vehicle in
front when that vehicle is at a standard
distance, between that of the other two
settings.
With the system sensitivity set to "Far",
the system will warn the driver of a
possible collision with the vehicle in
front when that vehicle is at a greater
distance, thus providing the possibility
of acting on the brakes more lightly and
gradually. This setting provides the
drivers with the maximum possible
reaction time to prevent a potential
accident.
With the option set to "Near", the
system will warn the driver of a possible
collision with the vehicle in front whenthat vehicle is close. This setting offers
the driver a lower reaction time
compared to the "Med" and "Far"
settings, in the event of a potential
collision, but permits more dynamic
driving of the vehicle.
The system sensitivity setting is kept in
the memory when the engine is
switched off.
System limited operation signal
If the dedicated message is displayed,
a condition limiting the system
operation may have occurred. The
possible reasons of this limitation are
something blocking the camera view or
a fault.
If an obstruction is signalled, clean the
area of the windscreen indicated in
fig. 60 and check that the message has
disappeared.
Although the vehicle can still be driven
in normal conditions, the system may
be not completely available.
When the conditions limiting the system
functions end, this will go back to
normal and complete operation. Should
the fault persist, contact a Fiat
Dealership.System failure signalling
If the system switches off and a
dedicated message is shown on the
display, it means that there is a fault on
the system.
In this case, it is still possible to drive
the vehicle, but you are advised to
contact a Fiat Dealership as soon as
possible.
Radar indication not available
If conditions are such that the radar
cannot detect obstacles correctly, the
system is deactivated and a dedicated
message will be shown on the display.
This generally occurs in the event of
poor visibility, such as when it is
snowing or raining heavily.
The system can also be temporarily
dimmed due to obstructions such as
mud, dirt or ice on the bumper. In such
cases, a dedicated message will be
shown on the display and the system
will be deactivated. This message can
sometimes appear in conditions of high
reflectivity (e.g. tunnels with reflective
tiles or ice or snow). When the
conditions limiting the system
functioning end, it will go back to a
normal and complete operation.
In certain particular cases, this
dedicated message could be displayed
when the radar is not detecting any
vehicle or object within its view range.

turning the engine off and on again until
the RESET procedure is carried out.
Reset procedure
The iTPMS needs an initial
"self-learning" phase (with length
depending on the driving style and road
conditions: optimal conditions being
driving on a straight road at 80 km/h for
at least 20 minutes) which starts when
the RESET procedure is carried out
manually.
The RESET procedure must be carried
out:
whenever the tyre pressure is
modified;
when even only one tyre is changed;
when tyres are rotated/inverted;
when the space-saver wheel is fitted.
Before carrying out the RESET
procedure, inflate the tyres to the rated
pressure values specified in the inflation
pressure table (see "Wheels" paragraph
in the "Technical specifications"
chapter).
If the RESET procedure is not carried
out, in all above cases, the
warning
light may give false indications on one
or more tyres.
To carry out the RESET procedure, with
the car stopped and the ignition device
at MAR, use the Main Menu as follows:
go to "Vehicle info" and then to
"Reset tyre pressure";
press the "OK" and hold down (more
than 2 seconds);
the display will show the procedure
progress (with a graphic bar) till the
RESET is completed.
At the end of the RESET procedure the
display will show the "Reset saved"
message, indicating that the
self-learning has been started and you
will hear a beep. If the self-learning
procedure of the iTPMS system has not
been carried out correctly, you will not
hear any acoustic warning.
Operating conditions
The system is active for speeds above
15 km/h.
In a few situations such as sporty
driving, particular conditions of the road
surface (e.g. icy, snowy, unsurfaced
roads) the signalling may be delayed or
partial in detecting the contemporary
deflation of more than one tyre.
Under special conditions (e.g. car
loaded asymmetrically on one side,
damaged or worn tyre, fitting the
space-saver spare wheel, use of the
"Fix&Go Automatic" tyre repair kit, fitting
snow chains, fitting different tyres on
the axles) the system may provide false
indications 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 and the symbols "–
–" will appear next to the shape of the
car next to each tyre.
This warning is displayed also after the
engine has been switched off and then
on again if the correct operating
conditions are not restored.
In the case of abnormal signals, it is
recommended to perform the RESET
procedure. If the indications appear
again after a successful RESET, check
that the tyres used on all four wheels
are the same and that the tyres are not
damaged. As soon as possible, refit the
standard tyre instead of the
space-saver spare, remove the snow
chains (if possible), check correct load
distribution and repeat the RESET
procedure by driving on a clean,
tarmacked road. If the indications
persist, contact a Fiat Dealership.

SAFETY

88)Always drive with your hands on the
rim of the steering wheel so that the airbag
can inflate freely if required. Do not drive
with your body bent forward. Keep your
back straight against the backrest.
89)When there is an active passenger
airbag, DO NOT install rearward facing
child restraint systems on the front seat.
Deployment of the airbag in an accident
could cause fatal injuries to the child
regardless of the severity of the impact.
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.
90)To deactivate the airbags using the
instrument panel menu, see the description
in the "Knowing the instrument panel"
chapter, "Menu Options" paragraph.
91)Do not affix rigid objects to the
garment hooks or support handles.
92)Do not rest your head, arms or elbows
on the door, windows or the area in which
the Window bag is located to avoid
possible injury during airbag inflation.
93)Never lean your head, arms or elbows
out of the window.94)If, when the ignition device is turned to
MAR, thewarning light does not switch
on or stays on whilst driving, a fault may
have occurred in the restraint systems. In
this case the airbags or pretensioners may
not be deployed in an impact or, in a lower
number of cases, they may be deployed
accidentally. Contact a Fiat Dealership
immediately to have the system checked.
95)In some versions, in the event of a LED
OFFfailure (located on the dashboard
trim), thewarning light on the
instrument panel turns on and the
passenger side airbags are deactivated. In
some versions, in the event of a LED
ONfailure (located on the dashboard
trim), thelight on the console turns on.
96)On cars with side bags, do not cover
the front seat backrests with extra covers.
97)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.
98)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.99)If the ignition device is at MAR, even if
the engine is switched off, airbags may be
deployed when the vehicle is stationary
and hit by another 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
ignition device is set 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.
100)Malfunction of the
warning light is
indicated by the activation of an airbag
failure icon and dedicated message on the
instrument panel display. The pyrotechnic
charges are not disabled. Contact a Fiat
Dealership immediately to have the system
checked
101)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.
