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
106-118 Doblo GB 9-05-2008 12:09 Pagina 110

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.

204TECHNICAL SPECIFICATIONS
FUEL CONSUMPTION
The fuel consumption and CO2emis-
sion values listed in the table below are
determined based on homologation
tests laid down in the European Di-
rective 2004/3/EC.
To measure fuel consumption and
emissions the procedures below are
followed:
– Urban cycle:the vehicle is start-
ed with the engine cold and driven so
as to reproduce the speed and
gearshift profile specified in the Euro-
pean Directive. The cycle includes a
series of accelerations, decelerations,
driving at constant speed and standing
with the engine in idle. The maximum
speed reached during the cycle is
50km/h and the average speed is
19km/h.– Extraurban cycle:consecutive to
the urban cycle according to the spec-
ifications laid down in the European
Directive. The maximum speed
reached during the cycle is 120km/h
and the average speed is 63km/h.
– consumption:this is determined
through a weighted average of the
consumption measured for the urban
cycle (with approx. 37% weight) and
for the extraurban cycle (with approx.
63% weight).
IMPORTANT
In practice, fuel consumption may be
higher than the values determined
through the homologation tests. Be-
low are some of the main factors that
may result in a deviation between the
consumption measured during normal
use of the vehicle and that measured
during the homologation tests.1) Vehicle conditions: inadequate
maintenance, use of roof racks, trail-
ers, heavy load conditions, intense use
of the electrical devices and the air-
conditioning.
2) Driving style: frequent cold starts
to drive short stretches, incorrect
procedure to warm up the engine,
gearshifting, continuous driving at high
speeds, sudden acceleration and brak-
ing.
3) Traffic and road conditions: driving
in traffic, uphill or twisty roads, road
surface conditions.
4) Atmospheric conditions: intem-
perate climate, wind, rain, snow, dri-
ving at high altitudes.
5) Percentage town, out-of-town and
motorway driving.

PRACTICAL TIPS TO
REDUCE CONSUMPTION
AND ENVIRONMENTAL
POLLUTION
Vehicle conditions
1. Have checks and adjustments
carried out in accordance with the
“Scheduled Service Plan”.
2. Check the tyre pressure at inter-
vals of not more than 4 weeks (see
“Tyre pressure”). Too low tyre pres-
sure increases consumption as the
rolling resistance increases. In these
conditions the tyres wear faster and
performance deteriorates.
3. Use winter tyresonly in the sea-
sons where dictated by the climatic
conditions. Winter tyres not only in-
crease consumption but also tyre
noise.4. Do not travel in heavy load con-
ditions(vehicle overloaded): The
weight of the vehicle (especially when
driving in town) and its trim greatly af-
fect fuel consumption and stability.
5. Remove roof racks or ski racks
after use. These accessories reduce
the aerodynamics of the vehicle and
have a negative effect on fuel con-
sumption.
6. Ideally use a trailerto transport
particularly bulky objects.
7. It is preferable to use the air vents:
driving with the window open has a
negative effect on the aerodynamics of
the vehicle.
8. Use the electrical devices only for
the time strictly necessary. The rear
heated window, additional headlights,
windscreen wipers and heater fan
need a considerable amount of ener-
gy, consequently increasing fuel con-
sumption (up to 25% more in the ur-
ban cycle).9. Using the air-conditioning in-
creases consumption (up to 30% more
on average): use the air vents when
the outside temperature permits.
Driving style
1. After starting the engineit is
advisable to set off immediately and
slowly avoiding revving up the engine.
Do not warm up the engine with the
vehicle stationary either at idle or at
high speed: in these conditions the en-
gine in fact warms up more slowly, in-
creasing consumption, emissions and
wear of the mechanical devices.
2. Avoid revving upwhen starting
at traffic lights or before turning off the
engine. This action, like double-de-
clutching, is unnecessary and causes in-
creased fuel consumption and pollu-
tion.
