engine FIAT DOBLO COMBI 2015 2.G Workshop Manual

Driving style
❒Afterstarting the engineyou
should drive away immediately and
slowly, avoiding high revs. Do not
warm up the engine at low or high
revs when the vehicle is stationary;
this causes the engine to warm
up more slowly, thereby increasing
fuel consumption, emissions and
mechanical component wear.
❒Avoidpointless actionssuch as
revving up when at traffic lights or
before stopping the engine. The latter
action, like double-declutching, is
unnecessary and causes increased
fuel consumption and pollution.
❒Gear selection:select a high gear
as soon as possible (taking into
account normal engine operation and
traffic conditions) without pushing
the engine to high revs during the
intermediate gears. Using low gears
at high revs to get lively acceleration
increases fuel consumption, harmful
emissions and engine wear.❒Vehicle speed:fuel consumption
increases exponentially as the speed
of the vehicle increases. Keep your
speed moderate and as even as
possible, avoiding unnecessary
braking and acceleration, which
cause excessive fuel consumption
and increased emissions. Keeping a
safe distance from the vehicle in
front helps to maintain a steady
speed.
❒Acceleration:accelerating violently
severely affects consumption and
emissions. Acceleration should
be gradual and should not exceed
the maximum engine torque rate.
CONDITIONS OF USE
Cold starting
Short journeys and frequent cold
starts do not allow the engine to
reach optimum operating
temperature.
This results in a significant increase
in consumption levels (from +15
to +30% on the urban cycle) and
emissions.Traffic and road
conditions
Rather high consumption levels are
linked to situations with heavy traffic,
for instance when travelling in
queues with frequent use of the
lower gears or in cities with many
traffic lights. Winding mountain
roads and rough road surfaces also
adversely affect consumption.
Stops in traffic
During prolonged hold-ups (e.g.
level crossings) the engine should
be switched off.

IN AN EMERGENCY

CHANGING A WHEEL
The vehicle is originally equipped
with the Fix&Go automatic quick
tyre repair kit (see instructions in the
next section). As an alternative,
the vehicle may have a normal-sized
spare wheel.
Wheel changing and correct use of
the jack and spare wheel call for
some precautions, as listed below.
108) 109) 110) 111)
Note for one-way
tyres
One-way tyres have a few arrows on
the side indicating the rotation
direction. If a wheel is changed
(when punctured, for example) the
direction of the arrows on the spare
wheel tyre may not coincide with
the rotation direction of the wheel to
be replaced.
In these conditions, too, the tyre still
maintains its safety features.Anyway, it is recommended to have
the wheel repaired and refitted as
soon as possible, as the best
performance is achieved when the
rotation direction of all tyres
coincides with the one indicated by
the arrows.
Please note that:
❒the jack weight is 4 kg;
❒the jack requires no adjustment;
❒the jack cannot be repaired and in
the event of a fault it must be
replaced by another original one;
❒no tool other than its cranking device
may be fitted on the jack.
To change a wheel, proceed as
follows:
❒stop the vehicle in a position that is
not dangerous for oncoming traffic
where you can change the wheel
safely. The ground should be flat
if possible, and sufficiently firm;
❒stop the engine and pull the
handbrake;
❒engage first gear or reverse;
❒wear the reflective safety jacket
(compulsory by law in certain
countries) before getting out of the
vehicle;❒indicate that the vehicle has broken
down using the devices required by
the law in the current country (e.g.
warning triangle, hazard lights, etc.);
❒for Cargo versions fig. 180: move the
left front seat forward and operate
lever A to access the tool bag; take it
to the wheel that needs replacing;
❒for Doblò/Doblò Combi versions fig.
181: open the rear doors, inside the
compartment on the rear right side,
take the tool bag, unhooking the
elastic band from the buckle, and
take it next to the wheel to be
changed;
❒take wheel spanner B fig. 182 and
the extension with pentagonal fitting
C; inside the load area, fit extension
C on bolt A; use spanner B to lower
the wheel by unwinding the wire;

❒make sure that switch E fig. 200 for
the compressor is in position 0 (off),
start the engine, insert plug D fig. 199
into the power socket and switch on
the compressor by placing switch
E fig. 200 in position I (on). Inflate the
tyre to the pressure specified in the
"Cold tyre pressures" paragraph
in "Technical data" chapter. Check
tyre pressure on gauge F fig. 200
with compressor off to obtain a more
precise reading;❒if after 5 minutes it is still impossible
to reach at least 1.5 bar, disengage
the compressor from the valve and
power socket, then move the vehicle
forwards by approx. 10 metres in
order to distribute the sealant inside
the tyre evenly, then repeat the
inflation operation;
❒if after this operation it is still
impossible after 5 minutes to reach at
least 1.8 bar, do not start driving
since the tyre is excessively damaged
and the quick tyre repair kit cannot
guarantee proper hold, contact a Fiat
Dealership;
❒if reaching the tyre pressure specified
in paragraph “Inflation pressure” in
chapter “Technical Data”, start driving
immediately;
118) 119) 120)
❒after having driven for about 10
minutes, stop and recheck the tyre
pressure fig. 201; remember to apply
the handbrake;
❒if at least 1.8 bar pressure is read,
restore correct pressure (with engine
running and handbrake on) and
restart;
❒drive with the utmost care to the
nearest Fiat Dealership.
FOR CHECKING AND
RESTORING
PRESSURE ONLY
The compressor can also be used
solely for restoring pressure.
Release the quick coupling and
connect directly to the tyre valve fig.
202; in this way, the bottle will not
be connected to the compressor
and no sealing fluid will be injected.

118) affix the adhesive label in an
easy-to-see position for the driver
as a reminder that the tyre has
been treated with the quick tyre
repair kit. Drive carefully,
particularly on bends. Do not
exceed 80 km/h. Do not
accelerate or brake suddenly.
119) If the pressure has fallen below
1.8 bar, do not drive any further:
the automatic Fix&Go automatic
quick tyre repair kit cannot
guarantee the correct hold
because the tyre is too damaged.
Contact a Fiat Dealership.
120) Inform the Dealership that the
tyre has been repaired using the
quick tyre repair kit. Give the
booklet to the personnel charged
with handling the treated tyre.
IMPORTANT
28) Punctures caused by foreign
bodies can be repaired if the
damage does not exceed 4 mm on
the tread and on the shoulder of
the tyre.
IMPORTANT
2) Do not dispose of the can or the
sealing fluid as household waste.
Have them disposed of in
compliance with national and
local regulations.
EMERGENCY
STARTING
Go to a Fiat Dealership immediately
if warning light
stays on
constantly on the instrument panel.
JUMP STARTING
If the battery is flat, it is possible to
start the engine using an auxiliary
battery with the same capacity or a
little higher than the flat one.
Proceed as follows to start the
vehicle fig. 204:
❒connect the positive terminals (+
mark near the terminal) of the two
batteries using a suitable lead;
❒with a second lead, connect the
negative terminal (–) of the auxiliary
battery to an earthing point
on the
engine or the gearbox of the vehicle
to be started;
❒start the engine;
❒when the engine has been started,
remove the cables reversing the
order above.
If after a few attempts the engine
does not start, do not persist but
contact the nearest Fiat Dealership.
183

IMPORTANT Do not directly connect
the negative terminals of the two
batteries: any sparks may ignite the
explosive gas which could come
out of the battery. If the auxiliary
battery is installed on another
vehicle, avoid any metal parts on the
latter and the vehicle with the flat
battery from accidentally coming
into contact.
29)
121)
BUMP STARTING
Never bump start the engine by
pushing, towing or coasting
downhill. This could cause fuel to
flow into the catalytic converter and
damage it beyond repair.IMPORTANT Remember that the
brake booster and the electric
power steering system are
not active until the engine is started,
so you will need to apply much
more force to the brake pedal or
steering wheel.
IMPORTANT
29) Never use a fast battery-charger
for emergency starting of the
engine as this could damage the
electronic systems of your vehicle,
particularly the ignition and fuel
supply control units.
WARNING
121) This procedure must be
performed by qualified personnel
as incorrect actions may cause
high-intensity electrical discharge.
Furthermore, battery fluid is
poisonous and corrosive: avoid
contact with skin and eyes. Keep
naked flames away from the
battery. No smoking. Do not cause
sparks.

IN AN EMERGENCY

FUEL CUT-OFF
SYSTEM
This intervenes in the case of an
impact causing:
❒the fuel supply cut-off with the engine
consequently switching off;
❒the automatic unlocking of the doors;
❒the switching on of the interior lights;
❒switching on of the hazard warning
lights (to deactivate the lights press
the dedicated button on the
dashboard).
122)
When the system has been
triggered, the message “Fuel cut off,
see handbook” is displayed on
some versions.
Check carefully for fuel leaks, for
instance in the engine compartment,
under the vehicle or near the tank
area.
After a collision, turn the ignition key
to STOP to prevent the battery
from running down.
The following procedure should be
carried out to restore the correct
operation of the vehicle:
❒turn the ignition key to the MAR
position;❒activate the right direction indicator;
❒deactivate the right direction
indicator;
❒activate the left direction indicator;
❒deactivate the left direction indicator;
❒activate the right direction indicator;
❒deactivate the right direction
indicator;
❒activate the left direction indicator;
❒deactivate the left direction indicator;
❒turn the ignition key to the OFF
position.
WARNING
122) If, after an impact, you smell
fuel or notice leaks from the fuel
supply system, do not reactivate
the system to avoid the risk of fire.
LIFTING THE
VEHICLE
If the vehicle needs to be lifted, go
to a Fiat Dealership which is
equipped with the arm hoist or
workshop lift.
