2008 FIAT DOBLO Ac unit

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.
If you wish to have a radio
installed, after purchasing
the vehicle, first go to a Fiat
Dealership who will be able to
advise on the subject in order to
safeguard the life of the battery and
protect the vehicle electrical sys-
tem. Excessive absorption will drain
and damage the battery and may
invalidate the battery warranty. The
lack of protection provided with a
factory-fitted radio may adversely
affect the correct operation of the
vehicle diagnostic system.
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.

– becomes continuous when the dis-
tance between the vehicle and the ob-
stacle is less that 30 cm and stops im-
mediately if the distance raises;
– is constant if the distance is unvar-
ied.
IMPORTANTIn the event of a
parking sensor system failure, you will
hear an alarm signal when you engage
reverse gear.
The sensors are shaped to fit into the
bumpers and optimise scanning angles.
fig. 149
F0A0723b
PARKING SENSORS
(where provided)
Parking sensors are located in the
rear bumper to detect and inform the
driver (through an intermittent
acoustic signal) about the presence of
obstacles behind the vehicle.
ACTIVATION
Sensors will activate automatically
when engaging reverse gear.
The frequency of the acoustic alarm
will increase as the distance between
the vehicle and the obstacle decreas-
es.
BUZZER WARNINGS
When the reverse gear is engaged an
intermittent acoustic signal is auto-
matically activated (short beep to sig-
nal system activation).
The acoustic signal frequency:
– becomes louder as the reduction
of distance between the vehicle and
the obstacle decreases;Detection distances:
Central ray ................................130 cm
Corner action range ................ 60 cm
Min/max range ................... 25/180 cm
If several sensors signal an obstacle,
the control unit checks and indicates
the closest one.
The system will automatically cut out
also when reverse gear is engaged af-
ter a distance of 50 or after exceeding
the speed of 30 km/h.
For proper operation,
the parking sensors shall
always be clean from
mud, dirt, snow or ice. Therefore
keep the rear bumpers clean to
prevent irregular operation of
the parking sensors.

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”.

114DRIVING YOUR VEHICLE
The tow hitch must comply with the
current regulation, with reference to
Directive 94/20/EC and amendments.
Install a tow hitch which is suitable
for the towing capacity of the vehicle.
Use a unified coupling for the elec-
trical connections. The coupling is gen-
erally fitted on a specific mount fas-
tened to the tow hitch.
For electrical connection, a 7 or 13
pole 12VDC coupling must be used
(CUNA/UNI and ISO/DIN standards).
Follow the instructions provided by
the manufacturer of the vehicle and/or
the tow hitch.
Use the specific trailer light fusebox
for electrical connections.
An electric brake should be supplied
directly by the battery through a cable
with a cross section of no less than 2.5
mm
2.In addition to the electrical connec-
tion, only the lead for powering an
electric brake and the lead to power
a light inside the trailer not exceed-
ing 15W may be connected to the ve-
hicle’s electrical system.
For connections use the preset con-
trol unit with battery cable no less
than 2,5 mm
2.
FITTING DIAGRAM
The trailer tow hitch is to be fixed in
the points indicated (see diagram fig.
4).
The plate 1must have a minimum
thickness of 6 mm. The fastening
points 2will be equipped with shims
’16 x 2 mm. The tow hitch structure
is fastened in the points shown with Ø
by means of six M8 screws and four
M10 screws.
Fasten the tow hitch to the body and
trim the bumper with the frame pro-
vided with the assembly kit.
After fitting the tow hitch, the emp-
ty vehicle weight will increase by ap-
proximately 15.5 kg. The ABS system will not
control the trailer braking
system. Great care
should therefore be taken when
driving on slippery road surfaces.
Under no circumstances
modify the vehicle’s brak-
ing system for trailer
braking control. The trailer’s
braking system must be com-
pletely independent of the vehi-
cle’s hydraulic system.
TOW HITCH INSTALLATION
The towing device should be fas-
tened to the body by specialised per-
sonnel according to any additional
and/or integrative information supplied
by the Manufacturer of the device.

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.
