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

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.
