42GETTING TO KNOW YOUR VEHICLE
EOBD engine control system
failure
Under normal conditions, turning the
ignition key to MAR, the warning light
turns on, but it should go out as soon
as the engine is started. The initial
turning on indicates that the warning
light is working properly. If the warn-
ing light stays on or turns on when
travelling:
– glowing steadily: means a fault in
the supply/ignition system which could
cause high emissions at the exhaust,
possible lack of performance, poor
handling and high consumption levels.
On certain versions the dedicated
message is displayed.
In these conditions it is possible to
continue driving without however re-
quiring heavy effort or high speed from
the engine. Prolonged use of the ve-
hicle with the warning light on may
cause damages. Contact Fiat Deal-
ershipas soon as possible. The warn-
ing light goes off if the fault disappears,
but it is still stored by the system.
– flashing: indicates the possibility
of damage to the catalyst (see “EOBD
system” in this section). INJECTION SYSTEM

Dealershipas soon as possible. INCOMPLETE
DOOR LOCKING
(red)
On certain versions the warning
light turns on when one or more
doors or the tailgate are not proper-
ly shut.
On certain versions the dedicated
message is displayed; symbols

45GETTING TO KNOW YOUR VEHICLE
The presence of water in
the fuel circuit may cause
serious damage to the en-
tire injection system and cause ir-
regular engine operation. If the
warning light
cor èturns on
(on certain versions together
with the message on the display)
contact Fiat Dealership as soon
as possible to have the system re-
lieved. If the above indications
come on immediately after refu-
elling, water has probably been
poured into the tank: turn the en-
gine off immediately and contact
Fiat Dealership.
¢Y(
EXTERNAL LIGHT
FAILURE (amber)
The warning light turns on
when one of the following
lights is failing:
– sidelights
– brake lights (third brake light ex-
cluded)
– rear fog guards
– direction indicators
– number plate lights.

FAILURE -
FIAT CODE
(amber)
Turning the key to MARthe warn-
ing light shall flash only once and then
go off.
If with the ignition key at MAR, the
warning light stays on, this indicates a
possible failure (see “Fiat Code sys-
tem” in section “Dashboard and con-
trols”).
IMPORTANTThe turning on at
the same time of the warning lights
U
and Yindicates a failure of the Fiat
CODE system.
If with the engine running the warn-
ing light
Uflashes, this means that
the vehicle is not protected by the en-
gine inhibitor device (see “Fiat Code
system” in section “Dashboard and
controls”).
Contact Fiat Dealership to have all
the key memorised.

EMERGENCY
START-UP
If the Fiat code cannot deactivate the
engine immobilising system, the warn-
ing lights ¢(Y) and Ustay on and
the engine will not start. Follow the
emergency start-up procedure to start
the engine.
Read the whole procedure carefully
before trying to carry it out. If you
make a mistake, you must turn the ig-
nition key back to STOPand repeat
the whole operation from the begin-
ning (step 1).
1)Read the 5-figure electronic code
given on the CODE card.
2)Turn the ignition key to MAR.3)Press and hold down the accel-
erator pedal. The injection system
warning light Uwill come on for
about 8 seconds, and then go out. At
this point release the accelerator ped-
al and get ready to count the flashes
of the Uinjection warning light.
4) Count the number of flashes that
corresponds to the first figure of the
code on the CODE card, then press
the accelerator pedal and keep it there
until the Uwarning light comes on
for four seconds and then goes out;
release the accelerator pedal.
5) The Uwarning light will start
flashing again: after it has flashed the
number of times that corresponds to
the second figure on the CODE card,
press the accelerator pedal to the
floor and keep it there.
6)Do the same for the remaining fig-
ures on the CODE card.7)Once the final figure has been en-
tered, keep the accelerator pedal
pressed. The Uwarning light will light
up for four seconds and then go out;
release the accelerator pedal.
8)The Uwarning light will flash
rapidly for about 4 seconds to indicate
that the operation has been complet-
ed correctly.
9) Start the engine by turning the ig-
nition key from MARto AVV.
If, however, the Uwarning light
stays on, turn the ignition key to
STOPand repeat the procedure
from step 1).
IMPORTANT After an emergency
start-up, you should contact a Fiat
Dealership otherwise you will have
to repeat the procedure described
each time you want to start the en-
gine.

120IN AN EMERGENCY
If the battery is flat, you can use an-
other battery to start the engine. Its
capacity must be the same or slightly
greater than the flat battery.
Proceed as follows fig. 1:
1) Connect positive terminals (+) of
the two batteries with a jump lead.
2)With a second lead, connect the
negative terminal (–) of the auxiliary
battery and to an earthing point E
on
the engine or the gearbox of the ve-
hicle to be started.
IMPORTANTDo not directly
connect the two negative terminals:
sparks could ignite the flammable gas
from the battery. If the other battery
is fitted in a vehicle, prevent acciden-
tal contacts between the metal parts
of the two vehicles.
3) Start the engine.
4)When the engine has been start-
ed, remove the leads reversing the or-
der above.If the engine fails to start after a few
attempts, do not keep turning the key
but have the vehicle seen to at a Fiat
Dealership.

Do not carry out this
procedure if you lack ex-
perience; if it is not done
correctly it can cause very in-
tense electrical discharges. In ad-
dition, the fluid contained in the
battery is poisonous and corro-
sive. Avoid contact with skin and
eyes. You are also advised not to
put naked flames or lighted cig-
arettes near the battery and not
to cause sparks.
Under no circumstances
should a battery charger
be used to start the en-
gine: it could damage the elec-
tronic systems and in particular
the ignition and injection control
units.

144IN AN EMERGENCY
IF THE BATTERY
IS FLAT
First of all, read the “Vehicle main-
tenance” section for the steps to be
taken to avoid the battery running
down and to ensure it has a long life.
IF THE BATTERY IS FLAT
Charging should be slow at a low
amp rating for 24 hours. Charging for
a longer time may damage the battery.
Proceed as follows:
1) Disconnect the electrical system
from the battery terminals.
IMPORTANTWhere relevant,
switch the electronic alarm off with
the remote control.2)Connect the charger cables to the
battery terminals.
3)Turn on the charger.
4)When you have finished, turn the
charger off before disconnecting the
battery.
5)Reconnect the cables to the bat-
tery terminals. Make sure the polari-
ty is correct.JUMP STARTING
See “Jump starting”, in this chapter.
The liquid in the battery
is poisonous and corro-
sive. Do not let it touch
the skin or eyes. Recharging the
battery should be done in a well-
ventilated area away from naked
flames or possible sources of
sparks: explosion and fire risk.
Do not attempt to
recharge a frozen bat-
tery. Thaw it first other-
wise it could explode. If the bat-
tery froze, make sure that the in-
ternal elements are not broken
(short-circuit risk) and that the
casing is not cracked (risk of
spilling the poisonous and corro-
sive fluid).
Under no circumstances
should a battery charger
be used to start the en-
gine: it could damage the elec-
tronic systems and in particular
the ignition and injection control
units.

Modifications or repairs
to the fuel system that
are not carried out prop-
erly or do not take the system

SPARK PLUGS
The cleanness and soundness of the
spark plugs are very important for
keeping the engine efficient and pol-
luting emissions down.
The appearance of the spark plug, if
examined by an expert eyes, is a good
way of pinpointing a problem even if it
has nothing to do with the ignition sys-
tem. Therefore, if the engine has prob-
lems, it is important to have the spark
plugs checked at a Fiat Dealership.
The spark plugs must be
changed at the times
specified in the service
schedule. Only use the type of
plugs indicated. If the heat ratio
is less than required or the life
specified is not guaranteed, prob-
lems can arise.
