2018 FIAT FULLBACK oil

175)If you tow the vehicles with automatic
transmission with the driving wheels on the
ground (Type B) as illustrated, make sure
that the towing speed and distance given
below are never exceeded, causing
damage to the transmission. Towing speed:
30 km/h Towing distance: 80 km For the
towing speed and the towing distance,
follow the local driving laws and
regulations.
176)On vehicles with manual transmission,
do not tow the vehicle with the rear wheels
on the ground (Type B) as illustrated.
177)Never tow an automatic transmission
vehicle with the front wheels up (and the
rear wheels on the ground) (Type B) when
the automatic transmission fluid level is low.
This may cause serious and expensive
damage to the transmission.
178)When the engine is not running, the
brake booster and power steering pump do
not operate. This means higher brake
depression force and higher steering effort
are required. Therefore, vehicle operation is
very difficult.
179)Do not leave the ignition switch in the
“LOCK” position or the operation mode in
OFF. The steering wheel will lock, causing
loss of control.
180)On vehicles with Super Select 4WD II,
when you are going to tow another vehicle,
set the drive mode-selector to “4H”
position. Selecting “2H” drive may increase
the differential oil temperature, resulting in
possible damage to the driving system.
Further, the drive train will be subjected to
excessive loading possibly leading to oil
leakage, component seizure, or other
serious faults.OPERATION UNDER
ADVERSE DRIVING
CONDITIONS
On a flooded road
Avoid flooded roads. In the event
driving flooded roads, doing so may
cause the following serious damage to
the vehicle.
Engine stalling
Short in electrical components
Engine damage caused by water
immersion
After driving flooded roads, be sure to
have an inspection at a Fiat Dealership
and take the necessary measures or
repair.
On a wet road
When driving in rain or on a road with
many puddles a layer of water may
form between the tyres and the road
surface. This reduces a tyre’s frictional
resistance on the road, resulting in loss
of steering stability and braking
capability.
To cope with this, observe the following
items:
(a) Drive your vehicle at a slow speed.
(b) Do not drive on worn tyres.
(c) Always maintain the specified tyre
inflation pressures.On a snow-covered or frozen road
When driving on a snow-covered or
frozen road, it is recommended that you
use snow tyres or snow traction device
(tyre chains). Refer to the “Snow tyres”
and “Snow traction device (tyre chains)”
sections.
Avoid high-speed operation, sudden
acceleration, abrupt brake application
and sharp cornering.
Depressing the brake pedal during
travel on snowy or icy roads may cause
tyre slippage and skidding. When
traction between the tyres and the road
is reduced the wheels may skid and the
vehicle cannot readily be brought to a
stop by conventional braking
techniques. Braking will differ,
depending upon whether you have
anti-lock brake system (ABS). If you do
have ABS, brake by pressing the brake
pedal hard, and keeping it pressed. If
you do not have ABS, pump the brake
pedal with short rapid jabs, each time
fully applying and fully releasing for
greatest effect.
Allow extra distance between your
vehicle and the vehicle in front of you,
and avoid sudden braking.
Accumulation of ice on the braking
system can cause the wheels to lock.
Pull away from a standstill slowly after
confirming safety around the vehicle.

Fuse replacement
344) 345) 346) 347) 348) 349)
182)
1. Before replacing a fuse, always turn
off the electrical circuit concerned and
place the ignition switch in the “LOCK”
position or put the operation mode in
OFF.
2. Remove the fuse puller (A) from the
inside of the fuse block in the engine
compartment.
3. Referring to the fuse load capacity
table, check the fuse pertaining to the
problem.B. Fuse is OK
C. Blown fuse
NOTE If any system does not function
but the fuse corresponding to that
system is normal, there may be a fault
in the system elsewhere. We
recommend you to have your vehicle
checked.
4. Insert a new fuse of the same
capacity by using the fuse puller into
the same place at the fuse block.
WARNING
344)Never replace a fuse with another
with a higher amp rating; DANGER OF
FIRE. If a general protection fuse
(MEGA-FUSE, MIDI-FUSE) is activated,
contact a Fiat Dealership.
345)If the newly inserted fuse blows again
after a short time, we recommend you to
have the electrical system checked to find
the cause and rectify it.
346)Never use a fuse with a larger
capacity than specified or a substitute
(such as a cable or foil). Doing so could
cause the circuit wires to overheat and
create a fire.
347)Never replace a blown fuse with metal
wires or other material.
348)Before replacing a fuse, make sure
that the ignition key has been removed and
that all the other services are switched off
and/or disengaged.
349)If a general protection fuse for safety
systems (airbag system, braking system),
power unit systems (engine system,
transmission system) or steering system
blows, contact a Fiat Dealership.
IMPORTANT
182)If it is necessary to wash the engine
compartment, take care not to directly hit
the fuse box and the window wiper motor
with the water jet

REPLACEMENT OF
LAMP BULBS
350) 351) 352) 353) 354) 355) 356) 357) 358) 359) 360)
Before replacing a bulb, ensure the
lamp is off. Do not touch the glass part
of the new bulb with your bare fingers;
the skin oil left on the glass will
evaporate when the bulb gets hot and
the vapour will condense on the
reflector and dim the surface.
NOTE If you are unsure of how to carry
out the work as required, we
recommend you to consult a specialist.
Be careful not to scratch the vehicle
body when removing a lamp and lens.
When it rains, or when the vehicle has
been washed, the inside of the lens
sometimes becomes foggy.This is the same phenomenon as when
window glass mists up on a humid day,
and does not indicate a functional
problem. When the lamp is switched
on, the heat will remove the fog.
However, if water gathers inside the
lamp, we recommend you to have the
lamp checked.
Bulb location and capacity
When replacing a bulb, be sure to use a
new bulb of the same type, wattage,
and colour. If you install a different bulb,
the bulb could malfunction or fail to
come on and could lead to a vehicle
fire.

IN AN EMERGENCY
361)

Rear room lamp — Type 2
1. Insert a straight blade (or minus)
screwdriver into the notch of the lens
and pry gently to remove it. Remove the
bulb from the lamp holder.
NOTE Wrap a piece of cloth around the
tip of the screwdriver in order to avoid
scratching the lens.
2. To install the bulb, perform the
removal steps in reverse.NOTE When installing the lens, fit the
two tabs on one side of the lens into
the holes on the vehicle side before
fitting the two tabs on the opposite side
of the lens into the holes on the vehicle
side.
Glove box lamp
Have the glove box lamp bulb replaced
at a Fiat dealership.
WARNING
350)Before replacing the bulb, wait for the
exhaust ducts to cool down: DANGER OF
SCALDING!
351)Only replace the bulb when the
engine is off and the vehicle is in a safe
position that does not cause danger to the
traffic and allows for a safe replacement.
Also ensure that the engine is cold, to
prevent the risk of burns.352)Halogen bulbs contain pressurised
gas; in the case of breakage they may
burst.
353)Bulbs are extremely hot immediately
after being turned off. When replacing a
bulb, wait for it to cool sufficiently before
touching it. You could otherwise be burnt.
354)Handle halogen lamp bulb with care.
The gas inside halogen lamp bulb is highly
pressurized, so dropping, knocking, or
scratching a halogen lamp bulb can cause
it to shatter.
355)Never hold the halogen lamp bulb
with a bare hand, dirty glove, etc. The oil
from your hand could cause the bulb to
break the next time the headlamps are
operated fig. 0 fig. 423. If the glass surface
is dirty, it must be cleaned with alcohol,
paint thinner, etc., and refit it after drying it
thoroughly.
356)Always consult a specialist when
repairing or replacing the bulbs of high
intensity discharge headlamps. This is
because the power circuit, bulbs and
electrodes generate a high voltage that
could cause an electric shock.
357)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.
358)Only replace bulbs when the engine is
off. Also ensure that the engine is cold, to
prevent the risk of burns.
359)Do not install commercially available
LED-type bulbs. Commercially available
LED-type bulbs could adversely affect the
operation of the vehicle, such as by
preventing the lamps and other vehicle
equipment from operating properly.
