DIESEL ENGINES
Use diesel fuel for motor
vehicles complying with
European specifications
EN590 only. The use of other
products or mixtures may dam-
age the engine beyond repair and
invalidate the warranty. If the
tank is accidentally filled with oth-
er types of fuel, do not start the
engine and drain the tank. If the
engine has run even for a very
short time, you will also need to
drain the fuel supply circuit.AT THE FILLING
STATIONPETROL ENGINES
Use only unleaded petrol.
To prevent errors, the diameter of
the fuel tank filler is too small to in-
troduce a lead petrol pump filler.
Use petrol with a rated octane num-
ber (R.O.N.) not lower than 95.
IMPORTANTAn inefficient cat-
alytic converter will allow harmful ex-
haust fumes to be emitted and thus
contribute to air pollution.
IMPORTANTNever put even the
tiniest amount of leaded petrol in the
fuel tank of your vehicle even in an
emergency. You would damage the
catalytic converter beyond repair. 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.

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”.

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.

HOW TO USE
THE GEARS
Press the clutch fully before shifting
the gear stick into one of the positions
shown in the diagram in fig. 2(the di-
agram is also on the gear lever knob).
IMPORTANTOnly engage the re-
verse gear when the vehicle is com-
pletely stationary. With the engine
running, wait for at least 2 seconds
with the clutch pedal pressed to avoid
damaging the gears and scratching.To engage reverse (R) from neutral:
– shift the lever to the right and back.
For version 1.4
8Vand 1.6 16V, to en-
gage reverse (R) from neutral, raise
collar A-fig. 3set under the knob and
move the lever rightwards and then
backwards at the same time.

You must press the
clutch fully down to
change gear properly. It is
therefore essential that there is
nothing under the pedals. Make
sure that mats are lying flat and
do not get in the way of pedals.

110DRIVING YOUR VEHICLE
Some suggestions which may help
you to keep the running costs of the
vehicle down and lower the amount
of toxic emissions released into the at-
mosphere are given below.
GENERAL
CONSIDERATIONS
Vehicle maintenance
The overall state of the vehicle is an
important factor which has a marked
influence over fuel consumption and
driving comfort and on the life span of
your vehicle. For this reason care
should be taken to maintain your ve-
hicle by carrying out the necessary
checks and regulations in accordance
with the specifications given in the
SERVICE SCHEDULE (see sections:
spark plugs, idling, air cleaners, diesel
fuel filter, timing).Tyres
Tyre pressure should be checked at
least once every four weeks: if the
pressure is too low fuel consumption
increases as the resistance to the
rolling movement of the tyre is
greater. In this state, tyre wear is in-
creased and handling suffers which will
effect safety.
Unnecessary loads
Do not travel with too much load in
the boot. The weight of the vehicle
and its trim greatly effects consump-
tion and stability.
Roof rack/ski rack
Remove the roof rack or the ski rack
from the roof as soon as they are no
longer used.
These accessories reduce the aero-
dynamic penetration of the vehicle and
will increase consumption. Whentransporting particularly large objects,
use a trailer, where possible.
Electric devices
Use electric devices for the neces-
sary time only. The heated rear win-
dow, fog lights, windscreen wipers,
heater fan require large amounts of
electricity and increasing the request
for power will also increase fuel con-
sumption (up to +25% when driving in
towns).
Climate control system
The climate control system is an ad-
ditional load which greatly effects the
engine leading to higher consumption
(up to +20% in average). When the
temperature outside allows, use the
air vents where possible.
Aerodynamic accessories
The use of non-certified aerodynamic
items may adversely affect air drag and
consumption levels.
CONTAINING RUNNING COSTS AND POLLUTION

DRIVING STYLE
Starting
Do not warm the engine when the
vehicle is stationary or at high or low
revs: in this way the engine will warm
up gradually increasing consumption
and emissions. You should drive off
slowly straight away avoiding high revs
so that the engine will warm up more
quickly.
Unnecessary actions
Avoid revving the engine when
stopped at traffic lights or before
switching off the engine and avoid dou-
bling the clutch as these actions have
no purpose of modern vehicles and
serve only to increase consumption
and pollution.
Gear selection
As soon as the traffic and road con-
ditions allow it, shift to a higher gear.
Using a lower gear to liven up accel-
eration greatly increases consumption.
In the same way, improper use of the
higher gears will increase consump-tion, emissions and wear and tear on
the engine.
Top speed
Fuel consumption increases consid-
erably as speed increases. For exam-
ple, when accelerating from 90 to 120
km/h, fuel consumption increases up
to approximately +30%. Your speed
should be kept as even as possible and
superfluous braking and acceleration
avoided as this increases both con-
sumption and emissions. A “smooth”
driving style should be adopted by at-
tempting to anticipate manoeuvres to
avoid imminent danger and to keep a
safe distance from the vehicle in front
to avoid braking sharply.
Acceleration
Accelerating violently increasing the
revs will greatly effect consumption
and emission: acceleration should be
gradual and not exceed the maximum
torque.CONDITIONS OF USE
Cold starting
Frequent cold starting will not enable
the engine to reach optimal running
temperature. It follows, therefore, that
consumption will be higher (from +15
to +30% in towns) as will the pro-
duction of toxic emissions.
Traffic situations and road
conditions
Heavy traffic and higher consumption
are synonymous: for example, when
driving slowly with frequent use of
lower gears or in towns where there
are numerous traffic lights.
Also twisting roads, mountain roads
and rough road surfaces pay a heavy toll
on consumption.
Traffic hold-ups
During prolonged stops (traffic lights,
level crossings, etc.) the engine should
be switched off.

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.

118DRIVING YOUR VEHICLE
The following precautions should be
taken if the vehicle will not be used for
several months:
– Park the vehicle in covered, dry and
if possible well-ventilated premises.
– Engage a gear.
– Make sure the handbrake is not en-
gaged.
– Remove the cables from the bat-
tery terminals (first remove the cable
to the negative terminal), and check
the battery charge. If the vehicle is to
be stored for long periods the charge
of the battery should be checked
every month and recharged if it falls
below 12.5V.IMPORTANT Where relevant,
switch off the electronic alarm with the
remote control.
– Clean and protect the painted parts
using protective wax.
– Clean and protect the shiny metal
parts using special compounds readi-
ly available.
– Sprinkle talcum powder on the
rubber windscreen and rear window
wiper blades and lift them off the glass.
– Slightly open the windows.– Cover the vehicle with a cloth or
perforated plastic sheet. Do not use
sheets of non-perforated plastic as
they do not allow moisture on the ve-
hicle body to evaporate.
– Inflate the tyres to 0.5 bar above
the normal specified pressure and
check it at intervals.
– Do not drain the engine cooling
system.
