96GETTING TO KNOW YOUR VEHICLE
The correct operation of
front airbags, side airbags
and pretensioners is en-
sured only if the vehicle is not
overloaded.
Do not wash the seat
back in vehicles with side
airbags with pressurised
steam or water in automatic seat
washing stations.
The airbag does not re-
place seat belts but rather
increases their effective-
ness. Furthermore, the airbag is
not fired in the event of low
speed front collisions, side colli-
sions, rear-end shunts and roll-
overs. In these cases, the passen-
gers are only protected by the
seat belts which for this reason
must always be fastened.
Always drive with both
hands on the rim of the
steering wheel so that the
airbag is free to inflate during a
head-on collision, and protect
you from serious injury. Do not
drive with your body bending to-
wards the steering wheel, but sit
in an upright position with your
back resting against the seat.
Do not cover the back-
rest of front seats with
trims or covers that are
not suitable to be used with side
bags.
It is important to re-
member that the airbag
can be fired if the ignition
key is fitted and at MAR also if
the engine is not running and the
vehicle it is hit by another vehicle
travelling at suitable speed. As a
consequence, Fiat recommends
sitting children in their specific
restraint systems on the back
seat, which is the most protected
position possible. On the con-
trary, the airbags will not be fired
if the vehicle is crashed into when
the key is not inserted or turned.
Consequently, in this case, the
fact that the system is not fired
does not indicate a fault.

EOBD SYSTEM
The EOBD system (European On
Board Diagnosis) allows continuos di-
agnosis of the components of the ve-
hicle correlated with emissions.
Furthermore, the system warns the
driver of deterioration concerning the
emission system components by
means of the Uwarning light on the
instrument panel.
The objective is to:
– monitor system efficiency;
– warn when failures can increase
emissions over the threshold estab-
lished by the European regulations;
– warn of the need to replace dete-
riorated components.
Furthermore, the system is equipped
with a connector for interfacing with
specific tools used to read the error
codes stored in the control unit mem-
ory along with a set of diagnostic and
engine specific parameters.IMPORTANTAfter eliminating the
problem, your Fiat Dealershipwill
run a bench test to fully check the sys-
tem. In some cases, a long road test
may be required. Contact a Fiat Dealer-
ship as soon as possible if
the Uwarning light ei-
ther does not come on when the
key is turned to MAR or comes
on, with fixed or flashing light,
when travelling. Warning light U
operation can be checked by
means of special equipment by
traffic agents. Always comply
with the traffic regulations in
force in the country where you
are travelling.
SOUND SYSTEM
If the “Sound System” has not been
requested, the vehicle features an odd-
ment compartment on the dashboard.
Contact a Fiat Dealer-
ship if you want to install
a sound system after pur-
chasing your vehicle. Their staff
will advise you on how to safe-
guard the life of the battery. Ex-
cessive idle intake can damage
the battery and invalid the bat-
tery warranty as well.
LIGHT PRESETTING
The system consists of the following:
– sound system power wires;
– wires for front speakers on the
dashboard, doors (where provided)
and rear speakers for passengers
transport versions;
– sound system compartment;
– aerial wire and aerial.

104GETTING TO KNOW YOUR VEHICLE
On certain versions the cap has a
mechanical lock to be opened using
the door key. PROTECTING THE
ENVIRONMENT
Protecting the environment has been
the guiding principle in the design of
the Fiat Doblò right from the start.
The result is the use of materials and
creation of devices that can reduce or
considerably curtail harmful influences
on the environment.
The devices for curtailing petrol en-
gine emissions are the following:
– a three-way catalytic converter;
– Lambda sensors (oxygen sensors);
– a fuel evaporation system. Do not put naked flames
or lighted cigarettes near
the fuel filler hole as there
is a danger of fire. Do not bend
too close to the hole either so as
not to breathe in harmful
vapours.
IMPORTANTIf required, replace
the fuel cap with another genuine cap
to avoid affecting the efficiency of the
fuel vapour recovery system.
The devices for curtailing diesel en-
gine emissions are:
– an oxidising catalytic converter;
– an exhaust gas recirculation system
(E.G.R.).
– diesel particulate filter (DPF)
– Lambda probes (where provided).
Consequently, the Fiat Doblò is ready
to travel well ahead of the most strin-
gent international pollution control
standards.

106DRIVING YOUR VEHICLE
ENGINE
STARTING3)Press the clutch pedal fully down,
without pressing the accelerator.
4) Turn the ignition key to AVV
and let it go the moment the engine
starts.
If the engine does not start at the
first attempt, return the ignition key
to STOPbefore trying to start the
engine again.
If the warning lights ¢(Y) and U
stay on when the ignition key is at
MAR, turn the key to STOPand
then to MARagain; if the warning light
stays on, try with the other keys pro-
vided.
If you are still unable to start the en-
gine, perform the emergency start-up
procedure (see section “In an emer-
gency”) and go to a Fiat Dealership.
IMPORTANTNever leave the ig-
nition key at MARwhen the engine is
off.HOW TO START DIESEL
VERSIONS
1) Ensure that the handbrake is up.
2)Put the gear lever into neutral.
3)Turn the ignition key to MAR. In-
strument panel warning lights U, m
and ¢(Y) will come on.
4)Wait for warning lights Uand ¢
(Y) to turn off.
5) Wait for the instrument panel
warning light mto go out. The hot-
ter the engine is, the quicker this will
happen.
6)Press the clutch pedal down to
the floor without touching the accel-
erator.
7) Turn the key to AVVimmedi-
ately after the mwarning light goes
out. If you wait to long, you will lose
the benefit of the work done by the
glow plugs.

It is dangerous to let the
engine run in a garage or
other closed area. The
engine consumes oxygen and
gives off carbon dioxide, carbon
monoxide and other poisonous
fumes.
Do not touch the high
voltage cables (spark plug
leads) when the engine is
running.
STARTING PROCEDURE FOR
PETROL VERSIONS
1) Ensure that the handbrake is up.
2)Put the gear lever into neutral.

107DRIVING YOUR VEHICLE
HOW TO WARM UP THE
ENGINE AFTER IS HAS JUST
STARTED (petrol and diesel
versions)
– Begin to move forward slowly let-
ting the engine turn at medium revs.
Do not accelerate abruptly.
– Do not push the engine to its lim-
it for the first few kilometres. You are
recommended to wait until the
coolant temperature gauge starts
moving.
EMERGENCY START-UP
If the Fiat CODE system fails to
recognise that code transmitted by the
ignition key (instrument panel warning
light ¢(Y) on) the emergency start-
up can be performed by using the
CODE card code.
See section “In an emergency”. The warning light m
will flash (for approxi-
mately 60 seconds) at
start-up or during prolonged
cranking to signal a fault in the
glow plug heating system. You
can use the vehicle as usual if the
engine starts but you should con-
tact a Fiat Dealership as soon as
possible to have problem seen to.
If the engine does not start at the
first attempt, return the ignition key
to STOPbefore trying to start the
engine again.
If with key at MARwarning light ¢
(Y) stays on, turn the key to STOP
and then to MARagain; if the warn-
ing light stays on, try with the other
keys provided.
If you still cannot start the engine, get
in touch with Fiat Dealership.
IMPORTANTNever leave the ig-
nition key at MARwhen the engine is
off.Catalysed vehicles must
not be bump started
(pushed, towed or coast-
ed downhill) as this could cause
fuel to flow into the catalytic ex-
haust system and damage it be-
yond repair.
Remember that until
the engine has started the
brake booster and hy-
draulic power steering systems
will not work and a greater effort
will therefore be required to de-
press the brake pedal or turn the
steering wheel.

108DRIVING YOUR VEHICLE
IMPORTANTAfter a taxing drive
you should allow the engine to “catch
its breath” before turning it off by let-
ting it idle to allow the temperature in
the engine compartment to fall.
PARKING
Switch off the engine, pull up the
handbrake and engage a gear (1st gear
or reverse, according to whether the
vehicle is facing up or downhill) and
leave the wheels turned. If the vehi-
cle is left on a steep slope, wedges or
a rock should be used to lock the
wheels.
Do not leave the ignition key at
MARto prevent draining the battery.
Always remove the key when you
leave the vehicle.HANDBRAKE
The handbrake lever is located be-
tween the two front seats.
Pull the handbrake lever upwards un-
til the vehicle cannot be moved. Four
or five clicks are generally enough
when the vehicle is on level ground
while nine or ten may be required if
the vehicle is on a steep slope or laden.
IMPORTANTIf this is not the
case, take the vehicle to a Fiat Deal-
ership to have the handbrake adjust-
ed.
Instrument panel warning light x
will come on when the handbrake
lever is pulled up and the ignition key
is at MAR.
To release the handbrake:
1)Slightly lift the handbrake and
press release button A-fig.1.
2)Keep the button pressed in and
lower the lever. Warning light xwill
go out.
3)Press the brake pedal when car-
rying out this operation to prevent the
vehicle moving accidentally. STOPPING THE ENGINE
Turn the key to STOPwhile the
engine is idling.
A quick burst on the ac-
celerator before turning
off the engine serves ab-
solutely no practical purpose and
wastes fuel.
Never leave children un-
supervised in the vehicle.

CHEAP RUNNING
THAT RESPECTS THE ENVIRONMENT
LOOKING
AFTER EMISSION
CONTROL DEVICES
The correct use of pollution control
devices not only ensures respect for
the environment but also has an effect
on the vehicle’s performance. Keeping
these devices in good condition is
therefore a fundamental rule for dri-
ving that is easy on your pocket and
on the environment too.
The first step to take is to follow the
SERVICE SCHEDULE to the letter.
If your vehicle has a petrol engine use
only unleaded petrol.
If you have trouble starting, do not
keep turning the ignition key for long
periods. Be especially careful to avoid
bump starting the vehicle by pushing,
towing or rolling downhill: these are
all manoeuvres that can damage the
catalytic exhaust. Use an auxiliary bat-
tery for start-ups only.If the engine begins to “loose its
smoothness”, when travelling, contin-
ue your journey but reduce the de-
mands you are making on the engine
and have the vehicle seen to at a Fi-
at Dealershipas soon as possible.
When the instrument panel fuel re-
serve warning light comes on, fill up as
soon as possible. A low level of fuel
can cause an uneven supply of fuel to
the engine with the inevitable increase
in the temperature of the exhaust gas
and serious damage to the catalytic
converter.
Never run the engine with one or
more spark plugs disconnected, even
for testing purposes.
Do not warm up the engine by let-
ting it idle for a while before moving
off unless the outside temperature is
very low and, even in this case, only
do so for less than 30 seconds.
Do not install other heat shields and
do not remove those already fitted to
the catalytic converter and exhaust
pipe. Environmental protection has been
one of the guiding principles in the
production of the Fiat Doblò. It is no
accident that its pollution control
equipment is much more effective than
that required by current legislation.
Nonetheless, the environment can-
not get by without a concerted effort
from everyone.
By following a few simple rules you
can avoid harming the environment
and often cut down fuel consumption
at the same time.
On this subject, a few useful tips have
been given below to supplement those
marked by symbol #, at various points
of the handbook.
You are asked to read both the for-
mer and the latter carefully.

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.
JUMP STARTING
fig. 1
F0A0106b
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.

138IN AN EMERGENCY
IF A FUSE BLOWS
GENERAL
A fuse is an element for protecting
the electrical system. A fuse will trip
(i.e. it will blow) in the event of a fail-
ure or improper interventions in the
electrical system.
If an electrical device is not working,
check whether the respective fuse is
blown. The conductor A-fig. 40
should be intact. If it is not, replace the
fuse with another with the same am-
perage (same colour).
B- Undamaged fuse.
C- Fuse with broken filament.Remove the blown fuse with the
tongs provided D, which can be found
in the fusebox.

Never replace a broken
fuse with anything other
than a new fuse. Always
use a fuse of the same colour.
Never change a fuse
with another amperage:
FIRE RISK.
Do not attempt to re-
pair a blown MAXI-FUSE.
Go to a Fiat Dealership.
Before changing a fuse,
check the ignition key has
been removed and that
all the other electric devices have
been turned off/disabled.
If the fuse blows again,
have the vehicle inspect-
ed at a Fiat Dealership.
