check engine light FIAT 500L 2018 Owner handbook (in English)

88)SERIOUS DANGER: When there is an
active passenger airbag, DO NOT install
rearward facing child restraint systems on
the front seat. Deployment of the airbag
in a crash could cause fatal injuries to the
child regardless of the severity of the
collision. 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.
89)To deactivate the airbags using the
instrument panel display menu, see the
description in the "Knowing the instrument
panel" chapter, "Setup Menu" paragraph.
90)Do not affix rigid objects to the garment
hooks or support handles.
91)Do not rest your head, arms or elbows
on the door, on the windows or in the
window bag area to prevent injury during
deployment.
92)Never lean your head, arms or elbows
out of the window.
93)If, when the key 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.94)On some versions, in the event of
warning light failure, thewarning
light switches on and the explosive charges
of the passenger airbag are deactivated.
95)On vehicles with side bags, do not
cover the front seat backrests with extra
covers.
96)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.
97)If the car has been stolen or in
the event of an attempt to steal it, if it has
been subjected to vandalism or floods,
have the airbag system checked by a Fiat
Dealership.
98)The airbags may also be deployed
when the car is not moving, if the key is in
the ignition and turned to MAR 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.
99)The
LED warning light indicates the
passenger airbag protection status. If the
LED is off, passenger side 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 LED 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 LED
may remain off. In this case, to check
correct LED operation, switch the engine
off, wait for at least 5 seconds and switch
the engine on again. The LED may light
up with various intensity levels depending
on the vehicle conditions. The intensity may
also vary during the same key cycle.
100)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.
101)The airbag does not replace seat
belts but increases their efficiency.
Because front airbags are not deployed for
low-speed crashes, side collisions,
rear-end shunts or rollovers, occupants are
protected, in addition to any side bags,
only by their seat belts, which must
therefore always be fastened.
101

Cable disconnection
Once the engine has been started,
remove the cables proceeding as
follows:
disconnect the end of the cable
used for negative (–) from the engine
earth of the car with flat battery;
disconnect the other end of the
cable used for negative (–) from the
negative terminal (–) of the auxiliary
battery;
disconnect the end of the cable
used for positive (+) from the positive
terminal (+) of the auxiliary battery;
disconnect one end of the cable
used for positive (+) from the positive
terminal (+) of the car with flat battery.
If it is often necessary to perform a
jump starting, have the car battery and
the recharging system checked by a
Fiat Dealership.
BUMP STARTING
Never bump start the engine by
pushing, towing or coasting downhill.
IMPORTANT Remember that the brake
servo and electric power steering are
not active until the engine is started. A
much greater effort will therefore be
required to use the brake pedal or turn
the steering wheel.IMPORTANT Any accessories (e.g.
mobile phones, etc.) connected to the
vehicle power sockets draw current
even if they are not used. These
devices, if left connected too much time
with engine off, may cause the battery
to drain with following reduction of
its life and/or failure to start the engine.
WARNING
140)Do not get too close to the radiator
cooling fan: the electric fan may start;
danger of injury. Scarves, ties and other
loose clothing might be pulled by moving
parts.
141)Remove any metal objects (e.g. rings,
watches, bracelets), that might cause an
accidental electrical contact and cause
serious injury.
142)The batteries contain acid that can
burn skin or eyes. Batteries produce
hydrogen, which is easily flammable and
explosive. Thus keep away flames or
devices which may cause sparks.
143)This starting procedure must be
performed by expert personnel because
incorrect actions could cause electrical
discharge of considerable intensity.
Furthermore, battery fluid is poisonous and
corrosive: avoid contact with skin and
eyes. Keep naked flames and lighted
cigarettes away from the battery and do
not cause sparks.
WARNING
67)Do not connect the cable to the
negative terminal (–) of the flat battery. The
following spark could lead to battery
explosion and cause serious harm. Only
use the specific earth point; do not use any
other exposed metallic part.
68)Never use a fast battery-charger to
start the engine as this could damage the
electronic systems of your vehicle,
particularly the ignition and engine fuel
supply control units.
144
IN AN EMERGENCY

FUEL CUT-OFF
SYSTEM
144)
This intervenes in the case of an impact
causing:
the interruption of the fuel supply
with the engine consequently cutting
out;
the automatic unlocking of the
doors;
turning on the lights inside the car;
the switching on of the hazard
warning lights.
The intervention of the system is
indicated by a message shown on the
display.
IMPORTANT Carefully check the vehicle
for fuel leaks, for instance in the engine
compartment, under the vehicle or
near the tank area. After an impact, turn
the ignition key to STOP to prevent the
battery from running down.
Reset procedure
To restore correct operation of the
system, carry out the following Reset
procedure (the procedure must be
completed in less than 1 minute):
turn the ignition key to the MAR
position;
activate the right direction indicator
and then stop it;
activate the left direction indicator
and then stop it;
activate the right direction indicator
and then stop it;
activate the left direction indicator
and then stop it;
turn the ignition key to the STOP
position and then to MAR.
LPG versions: in case of collision, the
petrol feed is immediately closed, the
LPG safety solenoid valves are closed
and injection is interrupted to stop
the engine.
Natural Power versions: in the event
of an impact, the power supply is
immediately cut off, causing engine
switching off.
WARNING
144)If, after an impact, you smell fuel or
notice leaks from the fuel system, do
not reactivate the system to avoid the risk
of fire.
TOWING THE
VEHICLE
ATTACHING THE TOW
RING
145) 146) 147) 148)
The tow rings, which are supplied with
the car, are housed in the tool box,
under the carpet in the luggage
compartment.
IMPORTANT The shorter tow ring is for
use on the front of the car and the
longer one on the rear.
500L WAGON versions
NOTE 500L WAGON versions have
only one tow ring, which can be used
on either the front or the rear bumper.

SCHEDULED
SERVICING
Correct servicing is crucial for
guaranteeing a long life for the vehicle
under the best conditions. For this
reason, Fiat has planned a series of
checks and services at fixed distance
intervals and, where provided, at fixed
time intervals, as described in the
Scheduled Servicing Plan.
Before each coupon however you
always need to pay attention to what is
written in the Scheduled Servicing
Plan (e.g. periodically check liquid
levels, tire pressure, etc.).
Scheduled Servicing is offered by all
Fiat Dealerships according to a set time
schedule. If, during each operation, in
addition to the ones scheduled, the
need arises for further replacements or
repairs, these may be carried out with
the owner's explicit agreement only.
If your car is used frequently for towing,
the interval between one scheduled
servicing operation and the next should
be reduced.IMPORTANT The Scheduled Servicing
coupons are prescribed by the
Manufacturer. Failure to carry them out
can cause the guarantee to decline. It is
advisable to inform a Fiat Dealership of
any small operating irregularities without
waiting for the next scheduled service
deadline.PERIODIC CHECKS
Every 1,000 kmor before long trips
check and, if necessary, top up:engine coolant level;
brake fluid level;
windscreen washer fluid level;
tyre inflation pressure and condition;
operation of lighting system
(headlights, direction indicators, hazard
warning lights, etc.);
operation of windscreen washer/
wiper system and positioning/wear of
rear window wiper blades.
Every3,000km, check and top up if
required: engine oil level.For 0.9
TwinAir Turbo versionsevery3,000
km check the engine oil level and
top it up to the maximum level, if
necessary.

SERVICING AND CARE

ENGINE OIL
152)70) 71)3)
Check that the oil level is between the
MIN and MAX references on the
dipstick A. If the oil level is near or even
under the MIN mark, add oil using the
filler B to reach the MAX mark.
Take out the engine oil dipstick A, clean
it with a lint-free cloth and reinsert it.
Extract the engine oil dipstick again and
check that the level is between the
MIN and MAX marks on the dipstick.
0.9 TwinAirTurbo versions only
Unscrew the cap, clean the dipstick
with a lint-free cloth, reinsert the
dipstick and screw the cap back on.
Unscrew the cap again and check that
the engine oil level is between the
MIN and MAX marks on the dipstick.
NOTE On 0.9 TwinAirTurbo versions, if
the instrument panel display shows
the message warning that the engine oil
needs to be topped up to the MAX
level, after topping up to the MAX level
the instrument panel Setup Menu
must be used to confirm that this has
been done (see “Display” section of
“Knowing your instrument panel”
chapter).Engine oil consumption: the
maximum engine oil consumption is
usually 400 grams every 1000 km.
During the initial period of use the
engine oil consumption conditions
should be considered as having
stabilised after the first 5000 - 6000
km.
ENGINE COOLANT FLUID
153)72)
If the level is too low, unscrew the cap
of reservoir C and add the fluid
described in the "Technical
Specifications" chapter.
WINDSCREEN/REAR
WINDOW WASHER FLUID
154) 155)
If the level is too low, lift reservoir cap D
and add the fluid described in the
"Technical Specifications" chapter.
IMPORTANT The headlight washer
system will not operate when the fluid
level is low, even though the
windscreen/rear window washer
continues to operate. On some
versions there is a reference notch on
the dipstick: ONLY the windscreen/rear
window washer operates with the
level below this reference.BRAKE FLUID
156) 157)73)
Check that the fluid is at the max. level.
If the fluid level in the reservoir is too
low, undo reservoir cap E and add the
fluid described in the "Technical
Specifications" chapter.
DUALOGIC
TRANSMISSION FLUID
4)
The transmission fluid level should only
be checked at a Fiat Dealership.
BATTERY
158) 159) 160) 161)5)74)
The battery does not require the
electrolyte to be topped up with distilled
water. A periodic check carried out at
a Fiat Dealership is, however, necessary
to check efficiency.
IMPORTANT After the battery is
disconnected, the steering must be
initialised. The
warning light on the
instrument panel switches on to
indicate this. To carry out this
procedure turn the steering wheel all
the way from one end to the other
or drive in a straight line for about a
hundred metres.

SERVICING AND CARE

In the event of extended inactivity the
display will show the average of the
indices until that moment (the "Average
index"), then the indices will be
coloured again in real time as soon as
the vehicle is restarted.
To check the data average of previous
route (the "route" starts when the
ignition key is turned to MAR and stops
when it is turned to STOP), select the
"Previous route" button.
The details of the previous trip can also
be displayed by pressing the "Details"
button, in which journey duration (time
and mileage) and average speed will be
reported.
Trip data storage and transfer
The trip data can be stored in
the system memory and transferred
using a suitably configured USB
memory stick or theUconnect™ LIVE
App.
This allows you to display the history of
the collected data, showing the
complete analysis of the trip data and
of your driving style.
For further information visit the
www.driveuconnect.eu websiteIMPORTANT Do not remove the USB
memory stick nor unpair the
smartphone and theUconnect™ LIVE
App before the system has
downloaded the data, since these
could be lost. During the transfer of
data to the devices,Uconnect™
messages may appear on the display
to guide the user correctly through
the operation; follow these instructions.
These messages are only displayed
with the ignition key at STOP and when
a delay in theUconnect™system
switching off is set. The data are
automatically transferred to the devices
when the engine is switched off.
Transferred data will be deleted from
the system memory in this manner. You
can choose to store the trip data or
not, by pressing the "Settings" button
and by setting the storage activation
and the USB or Cloud transfer mode.
When the USB memory stick is full, the
dedicated messages are shown on
theUconnect™system display.
