Light FIAT DOBLO 2007 1.G Service Manual

90GETTING TO KNOW YOUR VEHICLE
To exploit the ABS system to the full
in the event of necessity, you should
take heed of the following advice:
Braking while cornering always re-
quires extreme care even when using
ABS.
The most important advice to follow
is this The ABS exploits the
road hold available as
much as possible but can-
not increase it. You should always
drive carefully on slippery sur-
faces and avoid any unnecessary
risks.
If the ABS system cuts in
it is a sign that the grip
between the tyre and the
road surface has reached the lim-
it: you must slow down to match
the speed to the road grip avail-
able.
If there is a fault, the in-
strument panel warning
light >will come on. At
this point, reduce speed and go to
a Fiat Dealership to have your ve-
hicle checked and put right im-
mediately.
When the ABS cuts in,
and you feel the brake
pedal pulsating, do not re-
move your foot, but keep it
pressed. In doing so you will stop
in the shortest amount of space
possible under the current road
conditions.
If you follow these tips you will be
able to brake better in any situation.
IMPORTANTVehicles fitted with
may only be fitted with wheel rims,
tyres and brake pads of the make and
model approved by the vehicle man-
ufacturer.
The system is completed with an
EBD electronic brake force distribu-
tor which increases the brake system
performance and employs the ABS
control unit and sensors.
The vehicle is fitted with
an electronic braking de-
vice (EBD). The >and
xwarning light will come on at
the same time when the engine
is running to indicate that there
is an EBD system failure. In this
case violent braking may be ac-
companied by early rear wheel
locking with the possibility of
skidding. Drive the vehicle ex-
tremely carefully to the nearest
Fiat Dealership to have the sys-
tem checked.

91GETTING TO KNOW YOUR VEHICLE
The cushion immediately inflates,
placing itself as a protection between
the body of the front occupants and
the structure that could cause injuries.
Immediately after, the cushion deflates.
The front air bag (driver and pas-
senger) is not a replacement of but
complementary to the use of belts,
which should always be worn, as spec-
ified by law in Europe and most non-
European countries.
In case of crash, a person not wear-
ing the seat belt moves forward and
may come into contact with the cush-
ion while it is still inflating. Under this
circumstance the protection offered
by the airbag is reduced.
Front airbags may not activate in the
following situations:
– in collisions against highly de-
formable objects not affecting the ve-
hicle front surface (e.g. bumper colli-
sion against guard rail); If the xbrake fluid low
warning light comes on,
stop the vehicle immedi-
ately and contact the nearest Fi-
at Dealership. Fluid leaks from
the hydraulic system, in fact, can
compromise brake system oper-
ation, both traditional systems
and systems with ABS.FRONT AND SIDE
AIRBAGS
The vehicle can be fitted with front
air bags for the driver and passenger
and with side bags.
FRONT AIRBAGS
Front airbags (driver and passenger)
have been designed to protect the oc-
cupants in the event of head-on crash-
es of medium-high severity, by plac-
ing the cushion between the occupant
and the steering wheel or dashboard.
Front airbags are designed to protect
vehicle’s occupants in front crashes
and therefore non-activation in other
types of collisions (side collisions, rear
shunts, roll-overs, etc.) is not a system
malfunction.
In case of crash, an electronic con-
trol unit, when required, triggers the
inflation of the cushion according to
the severity of the collision. Warning light >alone,
with the engine running,
normally indicates a fault
in the ABS system only. In this
case, the braking system is still ef-
ficient, though without the anti-
locking device. Under these con-
ditions, performance of the EBD
system may be reduced. Also in
this case, you are advised to go
immediately to the nearest Fiat
Dealership, driving in such a way
to avoid sharp braking to have
the system checked.

93GETTING TO KNOW YOUR VEHICLE
Manual deactivation
The passenger side airbag can be de-
activated if it is absolutely necessary to
carry a child in the front passenger
seat.
Deactivation / reactivation shall be
carried out with ignition device at
STOP. Turn the specific switch fig.
142on the dashboard on passenger
side with the ignition key.IMPORTANTOperate the switch
only with engine off and ignition key
removed.
The switch fig. 142has two posi-
tions:
– Passenger front airbag on: (position
ON P): instrument panel warning
light
Foff. Do not carry children on
the front seat.
– Passenger front airbag off: (position
OFF F): instrument panel warning
light Fon. A child can be carried on
the front seat with a suitable restraint
system.
Warning light Fon the cluster
stays on permanently until the pas-
senger’s airbag is reactivated.
Deactivation of the passenger’s front
air bag does not inhibit operation of
the side air bag.SERIOUS DANGER:
With passenger’s
air bag active (ON),
never place child’s seats with the
cradle facing backwards since the
air bag activation could cause to
the child serious injuries, even
mortal. In the case of need, al-
ways deactivate the passenger’s
air bag when a child’s seat is
placed on the front seat. The
front passenger’s seat shall be ad-
justed in the most backward po-
sition to prevent any contact be-
tween child’s seat and dashboard.
Even if not compulsory by law,
you are recommended to reac-
tivate the air bag immediately as
soon as child transport is no
longer necessary.

95GETTING TO KNOW YOUR VEHICLE
Pretensioners, front airbags and side
airbags are triggered by the electron-
ic control unit according to different
types of impacts. Missed triggering of
the system, consequently, does not in-
dicate a fault in the system.
If when turning the key
to MAR the warning light
¬does not turn on or if it
stays on when travelling there
could be a failure in safety sys-
tems; in this event air bags or
pretensioners could not trigger in
case of impact or, in a minor
number of cases, they could trig-
ger accidentally. Contact Fiat
Dealership immediately to have
the system checked.When the passenger’s
front airbag is active (pas-
senger front airbag deac-
tivation switch at ON), the
F
warning light will come on for ap-
proximately four seconds and
flash for other four seconds when
the ignition key is turned to MAR
to remind the driver than the
passenger’s front and side airbags
(where fitted) will be fired in the
event of a crash. The warning
light should go out immediately
afterwards.
If an attempt has been
made to steal the vehicle,
or if it has actually been
stolen or has been vandalised in
any way or subjected to flooding,
have the airbag system checked
over at a Fiat Dealership.The front air bag is trig-
gered for shocks greater
in magnitude that the
pretensioners. For impacts be-
tween these two thresholds, it is
therefore normal that only the
pretensioners are triggered.
Do not apply stickers or
other objects to the
steering wheel or to the
dashboard on the passenger’s
side. Do not travel with objects
on your lap or in front of you nor
with a pipe, pencil or similar be-
tween your lips; you could seri-
ously hurt yourself if the airbag
inflates in a collision.

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.

103GETTING TO KNOW YOUR VEHICLE
If the outside temperature is very
low, the diesel thickens due to the for-
mation of paraffin and could clog the
fuel filter.
In order to avoid these problems, dif-
ferent types of diesel are distributed
according to the season: summer type,
winter type and arctic type (cold
mountain areas).
If refuelling with diesel fuel not ade-
quate, you are recommended to add
TUTELA DIESEL ARTto the fuel,
in the proportions written on the con-
tainer. Pour the antifreeze into the fu-
el tank before the fuel.
REFUELLING
To guarantee full tank filling, carry
out two refuelling operations after the
first click of the fuel delivery gun.
Avoid further topping up operations
that could cause damages to the fuel
system.FUEL FILLER CAP fig. 150
Make sure that the left-
hand sliding side door is
completely closed before
refuelling. You could damage the
door and the sliding lock system
which comes into play when the
fuel flap is open.
You cannot open the
left-hand sliding side door
while refuelling when the
flap is open.
fig. 150
F0A0219b
To open:
1)Turn the cap by approximately half
a turn anticlockwise and remove it.
IMPORTANTThe hermetic clo-
sure may cause a slight pressure in the
tank: a slight hissing when turning the
cap is quite normal.
2)While you are filling up, place the
cap on the fuel filler flap as illustrated
in the figure.
To close:
The cap has a bayonet coupling. In-
sert the cap and turn it clockwise un-
til it clicks once or more.

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.

105GETTING TO KNOW YOUR VEHICLE
DIESEL PARTICULATE
FILTER (DPF) (for Multijet
versions 1.3 85 HP and 1.9 120
HP)
The Diesel Particulate Filter is a me-
chanical filter, integral with the exhaust
system, that physically traps particulates
present in the exhaust gases of Diesel
engines.
The diesel particular filter has been
adopted to eliminate almost totally par-
ticulates in compliance with current /
future law regulations.
During normal use of the vehicle, the
engine control unit records a set of da-
ta (e.g.: travel time, type of route, tem-
peratures, etc.) and it will then calcu-
late how much particulates has been
trapped by the filter.Since this filter physically traps partic-
ulates, it shall be cleaned (reclaimed) at
regular intervals by burning carbon par-
ticles.
Reclaiming procedure is controlled
automatically by the engine control unit
according to the filter conditions and
the conditions of use of the vehicle.
During reclaiming the following phe-
nomena could take place: idling slight
increase, fan activation, slight smoke in-
crease, high exhaust temperatures.
These situations shall not be considered
as faults and they do not affect vehicle
performance and environment.
If the dedicated message is displayed,
refer to paragraph “Warning lights and
messages”.

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.
