2020 FIAT 500 engine

WARNING
143)Modifications or repairs to the electric
system that are not carried out properly
or do not take the system technical
specifications into account can cause
malfunctions leading to the risk of fire.
144)Halogen bulbs contain pressurised
gas, in the case of breakage they may
burst causing glass fragments to be
projected outwards.
145)Only replace the light bulbs when the
engine is off and in a position that does
not interfere with traffic and lets you safely
replace them (see the description in the
“Replacement” paragraph). Also ensure
that the engine is cold, to prevent the risk
of burns.
146)Before replacing the bulb, wait for the
exhaust ducts to cool down: DANGER
OF SCALDING!147)Due to the high power supply voltage,
gas discharge bulbs (Xenon) should only
be replaced by specialised personnel:
danger of death! Contact a Fiat Dealership.
WARNING
49)Halogen bulbs must be handled
holding the metallic part only. Touching the
transparent part of the bulb with your
fingers may reduce the intensity of the
emitted light and even reduce the lifespan
of the bulb. In the event of accidental
contact, wipe the bulb with a cloth
moistened with alcohol and let the bulb
dry.
50)Where possible, it is advisable to have
bulbs changed at a Fiat Dealership. The
correct operation and direction of the
external lights are absolutely essential for
the safety of the car and of compliance
with the law.
51)The intervention must be carried out
taking all precautions necessary to avoid
damaging the bodywork (please use a
sufficiently rigid and appropriately thick
plastic card).

REPLACING A
WHEEL
GENERAL
INSTRUCTIONS
154) 155) 156) 157) 158) 159) 160) 161) 162)
JACK
Please note that:
the jack weight is 1.76 kg;
the jack requires no adjustment;
the jack cannot be repaired and in
the event of a fault it must be replaced
by another genuine one;
no tool other than its cranking
device may be fitted on the jack.
MAINTENANCE
prevent any dirt from depositing on
the "worm screw"
keep the "worm screw" lubricated
never modify the jack.
CONDITIONS OF
NON-USE
at temperatures lower than -40°C on
a sandy or muddy ground
on uneven ground
on steep roads
in extreme weather conditions:
thunderstorms, typhoons, hurricanes,
blizzards, storms, etc.
in direct contact with the engine or
for repairs under the car
on boats.
RAISING WITH A JACK
AND REPLACING A
WHEEL
To change a wheel, proceed as follows:
stop the car in a position that is
not dangerous for oncoming traffic
where you can change the wheel safely.
The ground must be flat and sufficiently
compact;
stop the engine, pull up the
handbrake and engage the first gear or
reverse. Wear the reflective safety
jacket (compulsory by law) before
getting out of the car;
raise the mat on the floor of the
luggage compartment;
undo the fastener B fig. 112;
take out the tool box C fig. 112 and
place it next to the wheel to be
changed;
take the space-saver wheel D fig.
112;
for vehicles with wheel cap: use the
screwdriver provided, applying leverage
to the dedicated opening on the outer
edge;
127

159)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. Never go
under the raised vehicle. If any work under
the vehicle is necessary, contact the Fiat
Service Network. Incorrect placing of
the jack can cause the vehicle to drop: 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 vehicle raised. If the vehicle is raised
more than necessary, everything can
become more unstable, with the risk of the
vehicle dropping violently. Thus, lift the
vehicle only as needed in order to access
the spare tyre.
160)Snow chains cannot be fitted to the
space-saver wheel. So, if a front (drive)
wheel is punctured and chains are needed,
a rear wheel should be fitted to the front
of the car and the space-saver wheel
should be fitted to the rear. In this way,
equipped with two normal drive wheels at
the front, they can be fitted with snow
chains, thus resolving the emergency
situation.
161)If the hub cap is not fitted correctly, it
may come off when the car is travelling.
Never tamper with the inflation valve. Never
introduce tools of any kind between rim
and tyre. Check tyre and space-saver
wheel pressures regularly, complying with
the values given in the "Technical
specifications" chapter.162)It is extremely dangerous to attempt
to change a wheel on the side of the
vehicle next to the driving lane: make sure
that the vehicle is at a sufficient distance
from the road, to avoid being run over.
163)Be very careful when removing/
refitting the hub cap due to the proximity of
the brake disc. We recommend using
heat protection gloves.
WARNING
53)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.
54)Contact a Fiat Dealership as soon as
possible to have the correct tightening
of the wheel bolts checked.

IN AN EMERGENCY

JUMP STARTING
If the battery is flat, a jump starting can
be performed using the battery and
the cables of another car, or using an
auxiliary battery. In all cases, the battery
used must have a capacity equal to or
a little higher than the flat one.
Jump starting may be dangerous if
carried out incorrectly: carefully follow
the procedures described below.
IMPORTANT NOTES
After turning the ignition key to STOP
and having closed the driver's side
door, wait at least one minute before
disconnecting the battery and then
reconnecting the electrical supply to the
battery.
Do not use an auxiliary battery or any
other source of external supply with
a voltage above 12 V: the battery, the
starter, the alternator and the electrical
system of the car could be damaged.
Do not attempt jump starting if the
battery is frozen. The battery could
break and explode!JUMP STARTING166) 167) 168)
56) 57) 58)
If the battery is flat, the engine may be
started using an auxiliary battery fig.
127, with the same capacity or a little
higher than the flat one.
Proceed as follows to start the car:
connect the positive terminals (+
mark near the terminal) of the two
batteries using a suitable lead;
with a second lead, connect the
negative terminal – of the auxiliary
battery to an earth point
on
the engine or the gearbox of the car to
be started;
start the engine;
when the engine has been started,
remove the leads reversing the order
above.For versions with Start&Stop
In the case of emergency starting,
NEVER connect the negative lead (–) of
the auxiliary battery to negative pole
(–) of the battery, but only to an earth
point on the engine/gearbox assembly.
If after a few attempts the engine does
not start, do not persist but contact
a Fiat Dealership.
IMPORTANT Do not directly connect
the negative terminals of the two
batteries: sparks could ignite explosive
gas released from the battery. If the
auxiliary battery is installed on another
car, prevent accidental contact
between metallic parts of the two cars.
BUMP STARTING
Never bump start the engine by
pushing, towing or driving downhill.
This could cause fuel to flow into the
catalytic converter and damage it
beyond repair.
IMPORTANT Remember that the brake
servo and electrical power steering
system (for versions/markets, where
provided) 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.

IN AN EMERGENCY

WARNING
166)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.
167)Remove any metal objects (e.g. rings,
watches, bracelets), that might cause an
accidental electrical contact and cause
serious injury.
168)Do not attempt to charge a frozen
battery: it must be thawed first, otherwise it
may explode. If freezing has occurred, the
battery should be checked by skilled
personnel to make sure that the internal
elements are not damaged and that the
body is not cracked, with the risk of leaking
poisonous and corrosive acid.
WARNING
56)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.57)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.
58)Never bump start the engine by
pushing, towing or coasting downhill. This
could cause fuel to flow into the catalytic
converter and damage it beyond repair.
FUEL CUT-OFF
SYSTEM
169)
This intervenes in the case of an impact
causing:
the fuel supply cut-off with the
engine consequently switching off
the automatic unlocking of the doors
turning on of the lights inside the
vehicle;
The intervention of the system is
indicated by a message shown on the
display.
IMPORTANT Carefully check the car for
fuel leaks, for instance in the engine
compartment, under the car or near the
tank area. After a collision, turn the
ignition key to STOP position to prevent
the battery from running down.
To restore the correct operation of the
vehicle, proceed as follows:
turn the ignition key to the MAR-ON
position
activate the right direction indicator
deactivate the right direction
indicator
