2018 FIAT 500X check engine light

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 when
that 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. 63 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.
If atmospheric conditions are not the
real reason behind this message, check
if the sensor is dirty. It could be
necessary to clean or remove any
obstructions in the area illustrated in
fig. 62.

SAFETY

This warning is displayed also when
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.

WARNING
90)Do not apply stickers or other objects
on the steering wheel, on the dashboard in
the passenger side airbag area, on side
upholstery on the roof or on the seats.
Never put objects (e.g. mobile phones) on
the passenger side of the dashboard since
they could interfere with correct inflation of
the passenger airbag and also cause
serious injury to the passengers.
91) 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.
92) 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.
93) To deactivate the airbags using the
instrument panel menu, see the description
in the "Knowing the instrument panel"
chapter, "Menu Options" paragraph.
94) Do not affix rigid objects to the
garment hooks or support handles. 95)
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.
96) Never lean your head, arms or elbows
out of the window.
97) If, when the ignition device is turned to
MAR, the
warning 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.
98) In some versions, in the event of a LED
OFF failure (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
ON failure (located on the dashboard
trim), thelight on the console turns on.
99) On cars with side bags, do not cover
the front seat backrests with extra covers.
100) 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.
101) 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. 102)
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.
103) 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
104) 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.
111

153)Never tamper with the inflation valve.
Never introduce tools of any kind between
the rim and the tyre. Check tyre and
space-saver wheel pressures regularly,
complying with the values given in the
"Technical specifications" chapter.
154) The jack is a tool developed and
designed only for changing a wheel, if a
tyre gets punctured or damaged, on the
vehicle with which it is supplied or on other
vehicles of the same model. Any other use,
e.g. to jack up other vehicle models or
different things, is strictly prohibited. Never
use it to carry out maintenance or repairs
under the vehicle or to change
summer/winter wheels and vice versa: we
advise you to contact a Fiat Dealership.
Never go under the raised vehicle: use it
only in the positions indicated. Do not use
the jack for loads higher than the one
shown on its label. Never start the engine
with car raised. If the car is raised more
than necessary, everything can become
more unstable, with the risk of the car
dropping violently. Thus, lift the car only as
needed in order to access the space-saver
spare wheel.
155) When turning the jack handle make
sure that it can turn freely without scraping
your hand against the ground. The moving
components of the jack ("worm screw" and
joints) can also cause injuries: do not touch
them. If you come into contact with
lubricating grease, clean yourself
thoroughly.FIX&GO AUTOMATIC
