elling at moderate speed without demanding excessive
effort from the engine. Prolonged use of the vehicle
with the warning light on may cause damage. Go to a
Fiat Dealership as soon as possible.
The warning light goes out after the fault disappears,

CHANGING A FUSE
GENERAL INFORMATION
The fuse is a protective device for the electric system: it
operates if there is a fault or improper intervention in the
system.
Check the state of the corresponding fuse when a device
does not work: the filament A-fig. 173 should be intact.
If it is not, replace the blown fuse with a new one of the
same amperage (same colour).
B intact fuse.
Cfuse with damaged filament.
To change a fuse, use the tweezer D located in the tool
box or the Fix&Go container (for versions/markets where
provided).
If the same fuse blows again, contact
a Fiat Dealership.
WARNING
Never replace a damaged fuse with metal
wires or other recycled material.
Do not replace one fuse with another of
greater amperage; FIRE HAZARD.
If a general protection fuse (MEGA-FUSE, MIDI-
FUSE) is activated, contact a Fiat Dealership.
Remove the key from the ignition and switch off
or disable all electrical devices before replacing
a fuse.
WARNING
To identify the protective fuse, see the tables on the fol-
lowing pages.
If a general protection fuse for safety sys-
tems (air bag system, braking system),
power unit systems (engine system, transmission
system) or steering system is triggered, contact a
Fiat Dealership.
