2018 FIAT 500X warning light

Warning lightWhat it means
yellowiTPMS
iTPMS failure
When an iTPMS system failure is detected, the light flashes for 75 seconds, then stays on and a warning
message appears. This also happens if there are one or more wheels without sensors, until initial
conditions are restored.
IMPORTANT Do not continue driving with one or more flat tyres as handling may be compromised. Stop
the vehicle, avoiding sharp braking and steering. Repair immediately using the dedicated tyre repair kit (see
the “Fix&Go Automatic kit” paragraph in the "In an emergency" chapter) and contact a Fiat Dealership as
soon as possible.
Tyre pressure low
The warning light switches on and a message is displayed to indicate that the tyre pressure is lower than
the recommended value and/or that slow pressure loss is occurring. In these cases, optimal tyre duration
and fuel consumption may not be guaranteed.
In any situation in which the dedicated message is shown on the display, it is ESSENTIAL to refer to the
contents of the "Wheels" paragraph in the "Technical data" chapter, strictly complying with the indications
that you find there.
Once the normal operating conditions of the car are restored, carry out the "Reset" procedure.
WARNING Do not continue driving with one or more flat tyres as the car handling may be compromised.
Stop the vehicle, avoiding sharp braking and steering.

Warning lightWhat it means
yellowINJECTION / 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.
24)
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 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 car 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.
57

Warning lightWhat it means
yellowLANE ASSIST SYSTEM
The warning light switches on as follows:
Warning light continuously on (white):
the system is activated, but the lane limits were not detected (the
lane lines are grey).
Warning light on and flashing (amber): the vehicle has approached the lane line and is about to pass it.
Warning light switched on continuously (green): the system has detected the limits of both lanes. The
system will act on the steering wheel if the lane was passed unintentionally.
yellow GLOW PLUG PREHEATING (Diesel versions)
This warning light comes on when the ignition device is brought to MAR and will switch off when the glow
plugs have reached the preset temperature. The engine can be started as soon as the warning light
switches off.
IMPORTANT In mild or high temperature conditions, the warning light comes on for a very short time only.
GLOW PLUG PREHEATING FAILURE (Diesel versions)
The warning light will flash to indicate a failure in the glow plug preheating system. In this case, contact a
Fiat Dealership as soon as possible.
yellow
FULL BRAKE CONTROL OFF
The warning light comes on when the Full Brake Control system is deactivated by the driver or in the event
of automatic deactivation following a temporary system failure. Contact a Fiat Dealership as soon as
possible.

WARNING
31)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.
32) 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.
33) If a failure is present with sharp braking, the rear wheels may lock and the vehicle may swerve.
IMPORTANT
24)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.
25) If the warning light (or the icon on the display) flashes whilst driving, contact a Fiat Dealership.
26) If the symbol switches on when driving, stop the engine immediately and contact a Fiat Dealership.
27) 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.
28) 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.
29) 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.
30) 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.
31) If the symbol flashes when driving, contact a Fiat Dealership.

KNOWING THE INSTRUMENT PANEL

System intervention
The intervention of the system is
indicated by the flashing of the
warning light on the instrument
panel, to inform the driver that the
vehicle is in critical stability and grip
conditions.
41) 42) 43) 44) 45)
TC (Traction Control)
SYSTEM
The system automatically operates in
the event of slipping, loss of grip on wet
roads (aquaplaning) and acceleration on
slippery, snowy or icy roads, etc. on
one or more drive wheels. Depending
on the slipping conditions, two different
control systems are activated:
if the slipping involves both drive
wheels, the system intervenes, reducing
the power transmitted by the engine;
if the slipping only involves one of the
drive wheels, the BLD (Brake Limited
Differential) function is activated,
automatically braking the wheel which
is slipping (the behaviour of a
self-locking differential is simulated).
This will increase the engine torque
transferred to the wheel which isn't
slipping. This function remains active
even if the "Systems partially disabled"
and "Systems disabled" modes are
selected (see description in the
following pages). System intervention
The intervention of the system is
indicated by the flashing of the
warning light on the instrument
panel, to inform the driver that the
vehicle is in critical stability and grip
conditions.
46) 47) 48) 49) 50)
PBA (Panic Brake
Assist) SYSTEM
The PBA system is designed to improve
the vehicle’s braking capacity during
emergency braking.
The system detects emergency braking
by monitoring the speed and force with
which the brake pedal is pressed, and
consequently applies the optimal brake
pressure. This can reduce the braking
distance: the PBA system therefore
completes the ABS.
Maximum assistance from the PBA
system is obtained by pressing the
brake pedal very quickly. In addition, the
brake pedal should be pressed
continuously during braking, avoiding
intermittent presses, to get the most
out of the system. Do not reduce
pressure on the brake pedal until
braking is not necessary anymore.
The PBA system is deactivated when
the brake pedal is released.
51) 52) 53)
HHC (Hill Hold Control)
SYSTEM
This is an integral part of the ESC
system and facilitates starting on
slopes, activating automatically in the
following cases:
uphill: vehicle stationary on a road
with a gradient higher than 5%, engine
running, brake pressed and
transmission in neutral or gear other
than reverse engaged;
downhill: vehicle stationary on a road
with a gradient higher than 5%, engine
running, brake pressed and reverse
gear engaged.
When setting off, the ESC system
control unit maintains the braking
pressure on the wheels until the engine
torque necessary for starting is
reached, or in any case for a maximum
of 2 seconds, allowing your right foot to
be moved easily from the brake pedal
to the accelerator.
When two seconds have elapsed,
without starting, the system is
automatically deactivated, gradually
releasing the braking pressure. During
this release stage it is possible to hear a
typical mechanical brake release noise,
indicating the imminent movement of
the vehicle.
