engine FIAT DOBLO COMBI 2016 2.G Service Manual

STARTING THE
ENGINE
The vehicle is fitted with an immobiliser:
if the engine fails to start, see the
paragraph on “The Fiat CODE system”
in the “Dashboard and controls”
section.
The engine may be noisier during the
first few seconds of operation,
especially after a long period of
inactivity. This is due to the hydraulic
tappets, the timing system chosen for
petrol engine versions to reduce the
number of servicing interventions, and
affects neither functionality nor reliability.

PROCEDURE FOR
PETROL VERSIONS
Proceed as follows:
engage the handbrake;
put the gear lever into neutral;
fully depress the clutch pedal,
without touching the accelerator;
turn the ignition key to AVV and
release it as soon as the engine starts.
If the engine does not start at the
first attempt, return the ignition key to
STOP before repeating the starting
procedure.
If, when the ignition key is on MAR, the
instrument panel warning light
remains on together with warning
light
, turn the key to STOP and
then back to MAR; if the warning light
remains on, try the other keys provided
with the vehicle. If you are still unable
to start the engine, perform the
emergency starting procedure (see
"Emergency starting" in the "In an
emergency" chapter) and contact a Fiat
Dealership.PROCEDURE FOR DIESEL
VERSIONS
Proceed as follows:
engage the handbrake;
put the gear lever into neutral;
turn the ignition key to MAR: the
warning lights
andon the
instrument panel will turn on;
wait for the warning lightsand
to switch off. The hotter the engine
is, the quicker this will happen;
fully depress the clutch pedal,
without touching the accelerator;
turn the ignition key to AVV as soon
as warning light
switches off.
Waiting too long will waste the heating
work carried out by the glow plugs.
Release the key as soon as the engine
starts.
IMPORTANT With the engine cold, the
accelerator pedal must be fully released
when you turn the ignition key to AVV.
If the engine does not start at the
first attempt, return the ignition key to
STOP before repeating the starting
procedure.
If, when the ignition key is at MAR the
warning light remains lit, turn the
key to STOP and then back to MAR; if
the warning light remains lit, try with the
other keys provided with the vehicle. If
you still cannot start the engine, contact
a Fiat Dealership.

STARTING AND DRIVING

19)
WARMING UP THE
ENGINE JUST AFTER IT
HAS STARTED
Proceed as follows:
drive off slowly, letting the engine
turn at medium revs. Do not accelerate
abruptly;
do not demand full performance at
first. Wait until the engine coolant
temperature gauge starts moving.
EMERGENCY STARTING
If the instrument panel warning light
stays on steadily, you can perform
an emergency starting by using the
code on the CODE card (see the “In an
emergency” section).
20)
STOPPING THE ENGINE
Turn the ignition key to STOP while the
engine is idling.
IMPORTANT After a taxing drive, you
should allow the engine to “catch
its breath” before turning it off by letting
it idle to allow the temperature in the
engine compartment to fall.
WARNING
17)It is advisable not to demand maximum
performance from your vehicle (e.g.
excessive acceleration, long distances at
high speeds, excessively intense braking,
etc.) during the initial period of use.
18)When the engine is off, do not leave
the key turned to MAR to prevent
unnecessary electrical consumption from
draining the battery.
19)If the indicator flashes for 60
seconds after starting or during an
extended towing period, this indicates
a problem in the glow plug pre­heating
system. Use the vehicle normally if the
engine starts, but contact a Fiat Dealership
as soon as possible.
20)Never start the engine by pushing,
towing or driving downhill. This could
cause fuel to flow into the catalytic
converter and damage it beyond repair.
WARNING
95)It is dangerous to run the engine in
enclosed areas. The engine takes in
oxygen and releases carbon dioxide,
carbon monoxide and other toxic gases.
HANDBRAKE
The handbrake lever is located between
the front seats. Pull the lever upwards
to engage the handbrake and ensure
that the vehicle does not move. The
vehicle should be secured after several
clicks of the lever. If it is not, contact
a Fiat Dealership to have it adjusted.
96)When the handbrake lever is engaged
and the ignition key is in MAR position,
the instrument panel warning light
will switch on.
Proceed as follows to release the
handbrake:
slightly lift the lever and press
release button A fig. 140;
keep button A pressed and lower
the lever. The
warning light in the
instrument panel will switch off.
Press the brake pedal when carrying
out this operation to prevent the vehicle
from moving accidentally.
PARKING
Proceed as follows:
stop the engine and engage the
handbrake;
engage the gear (on a slope, engage
first gear if the vehicle is facing uphill
or reverse if it is facing downhill) and
leave the wheels steered.
125

If the vehicle is parked on a steep
slope, it is advisable to block the
wheels with a wedge or stone.
To prevent draining the battery, do not
leave the ignition key turned to MAR.
Always remove the key when you leave
the vehicle.
Never leave children unattended in the
vehicle. Always remove the ignition
key when leaving the vehicle, and take
it with you.
WARNING
96)The vehicle should be secured after
several clicks of the lever. If it is not,
contact a Fiat Dealership to have it
adjusted.
USING THE
GEARBOX
To engage the gears, depress the
clutch pedal fully and shift the gear
lever A-fig. 127 into the required
position (the diagram is shown on the
gear knob fig. 141).
IMPORTANT Reverse may only be
engaged when the vehicle is at a
standstill. With the engine running, wait
for at least 2 seconds with the clutch
pedal fully pressed before engaging
reverse to prevent damage to the gears
and grating.
To engage reverse R from neutral, lift
ring B under the knob and at the same
time move the gear lever to the right
and then backwards (as shown in the
diagram).
97)
21)
WARNING
97)Depress the clutch pedal fully to
change gear correctly. Therefore, the floor
area underneath the pedal unit must not
be obstructed in any way. Ensure that the
floor mat is always laid flat and does not
interfere with use of the pedals.
WARNING
21)Do not drive with your hand resting on
the gear lever as the force exerted, even
if slight, could lead over time to premature
wear of the internal gearbox components.
The clutch pedal should be used only
for gear changes. Do not drive with your
foot resting on the clutch pedal, however
lightly. For versions/markets where
provided, the electronic clutch control
could cut in by interpreting the incorrect
driving style as a fault.

STARTING AND DRIVING

"ENERGY SAVING"
FUNCTION
(for versions/markets, where provided)
If, after the engine has been
automatically restarted, the driver does
not take any action for a period of
about 3 minutes, the Start&Stop
system will definitively stop the engine
to avoid fuel consumption.
The engine can only be started using
the key in such cases. N.B.: In any
case, it is possible to keep the engine
running by deactivating the Start&Stop
system.
IRREGULAR OPERATION
In the case of malfunctions the
Start&Stop system is disabled.
The driver is informed of the problem by
the general failure warning light A fig.
144, where provided, coming on with
an information message and the
system failure symbol B fig. 144 in the
control panel. In this case, contact a
Fiat Dealership.VEHICLE INACTIVITY

If the vehicle is inactive, special care
must be taken to disconnect the
battery electrical power supply. This
procedure must be carried out by
disconnecting the rapid-release
negative terminal A from the negative
dummy pole B because there is a
battery status monitoring sensor D on
the negative battery terminal C which
must never be disconnected, except if
the battery is replaced.
Versions without dummy pole fig.
146
In the event of vehicle inactivity, special
attention must be paid to the
disconnection of the battery power
supply.Proceed as follows: detach the
connector A (by pressing button B)
from sensor C for monitoring the status

WARNING
98)If the battery needs to be replaced,
always contact a Fiat Dealership. Replace
the battery with a new one of the same
type and specifications.
99)Before opening the bonnet, make sure
that the vehicle is switched off and the
key is in the OFF position. Please follow the
instructions on the decal near the front
crossmember. It is advisable to extract the
key when there are other people in the
vehicle.100)The vehicle should always be
evacuated after the key has been removed
or turned to the OFF position. When
refuelling, make sure that the vehicle is
switched off with the key in the OFF
position.
101)For vehicles with robotised gearbox,
in the event of automatic engine stopping
with the vehicle on a slope, the engine
should be restarted by moving the gear
lever towards (+) or (–) without releasing
the brake pedal. For vehicles with
robotised gearbox and Hill Holder function,
in the event of automatic engine stopping
with the vehicle on a slope, the engine
must be restarted by moving the gear lever
towards (+) or (–) without releasing the
brake pedal, so that the Hill Holder
function, active only with the engine
running, becomes available.
102)If climate comfort is to be favoured,
the Start&Stop system can be disabled, for
a continuous operation of the climate
control system.
TPMS (Tyre
Pressure
Monitoring System)
(for versions/markets, where provided)
103) 104) 105) 106) 107) 108) 109) 110) 111)
DESCRIPTION
The tyre pressure monitoring system
(TPMS) warns the driver of low tyre
pressure on the basis of the cold
inflation pressure prescribed for the
vehicle.
Changes in outside temperature may
cause tyre pressure to vary. This means
that a decrease in the outside
temperature corresponds to a decrease
in the tyre pressure.
Tyre pressure must always be adjusted
according to the cold inflation pressure.
Cold tyre inflation pressure is the tyre
pressure after letting the vehicle stand
for at least three hours or a travel
shorter than 1.6 km after an interval of
three hours.
The cold tyre inflation pressure must
not exceed the maximum inflation
pressure value printed on the side of
the tyre.
The tyre pressure also increases while
driving the vehicle: this is a normal
condition and does not require any
adjustment of the pressure.
NOTE
147F0V0043
130
STARTING AND DRIVING

The TPMS does not replace the
normal tyre maintenance service and
does not indicate any fault in a tyre.
Therefore, the TPMS should not be
used as pressure switch while adjusting
the tyre inflation pressure.
Driving with insufficient tyre pressure
causes their overheating and can
result in tyre failure. The low inflation
pressure reduces fuel efficiency and
tyre tread life and may also affect
handling and braking performance of
the vehicle.
The TPMS does not replace the
correct tyre maintenance. It is up to the
driver to maintain the correct tyre
pressure level measuring it with
a suitable pressure switch. This is
necessary even if the decrease in the
inflation pressure value does not cause
the tyre pressure control warning light
to switch on.
The TPMS warns the driver of any
condition of insufficient tyre pressure
If this drops below the insufficient
pressure limit for any reason including
low temperature and normal pressure
loss of the tyre.
The seasonal temperature changes
affect tyre pressure.The TPMS uses wireless devices with
electronic sensors mounted on the
wheel rims to constantly monitor the
value of tyre pressure. The sensors
mounted on each wheel as part of the
valve stem transmit various information
of the tyres to the receiver module, in
order to calculate the pressure.
IMPORTANT Monitoring and
maintaining the correct pressure in all
four tyres are particularly important.
Tyre pressure monitoring system
low pressure warning
The system warns the driver if one or
more tyres are flat by switching on
the warning light
on the instrument
panel (together with a warning message
and an acoustic signal).The TPMS continues to advise the
driver of the low tyre pressure condition
until this is corrected; the warning
continues until the pressure
corresponds or exceeds the pressure
prescribed for the cold tyres. When the
tyre low pressure control warning
light
switches on constantly, the
inflation pressure must be adjusted until
it reaches the pressure prescribed for
cold tyres. After the automatic update
of the system, the tyre pressure control
warning light switches off. You may
need to drive the vehicle for about 20
minutes at a speed higher than 20
km/h to allow the TPMS to receive this
information.
IMPORTANT In the case of deflation of
more than one tyre sequentially, without
switching off and on the engine, from
the second tyre involved the acoustic
signal is not activated, only the
dedicated signal is shown on the
display.
To prevent the signal from being stored
in the event of pressure loss of a
subsequent tyre (with deactivation of
the acoustic signal), the ignition key
must be turned to MAR and then to
STOP, each time pressure is restored.

Storing vehicle speed
Proceed as follows:
turn ring nut A fig. 148 to ON and
press the accelerator pedal so that the
vehicle reaches the desired speed;
move the stalk upwards (+) for at
least one second, then release it: the
vehicle speed is memorised and you
can therefore release the accelerator
pedal.
If necessary (when overtaking for
instance) acceleration is possible by
simply pressing the accelerator pedal:
releasing the accelerator pedal, the
vehicle will return to the speed
memorised previously.Restoring the stored
speed
If the device has been deactivated, for
example by depressing the brake or
clutch pedal, the stored speed can be
restored as follows:accelerate progressively until a
speed close to that stored is reached;
engage the gear selected at the time
that the speed was stored;
press button B fig. 148.
Increasing the stored
speed
This can be done in two ways:
by pressing the accelerator and
memorizing the new speed reached;
or
by moving the stalk upwards (+).
Each operation of the stalk will
correspond to a slight increase in
speed of about 1 km/h, while keeping
the stalk upwards will increase the
speed continuously.Reducing the stored
speed
This can be done in two ways:
by deactivating the device and then
storing the new speed
or
by moving the stalk downwards (-)
until the new speed, which will
automatically remain memorised, is
reached.
Each movement of the stalk will
correspond to a slight reduction in
speed of about 1 km/h, while keeping
the stalk held downwards will decrease
the speed continuously.
Deactivating the device
The device can be switched off by the
driver in the following ways:
by turning ring nut A to the OFF
position;
if the engine is stopped (leaving the
stalk ring nut at ON), when the ignition
key is next turned to ON, Cruise
Control will be activated automatically.

134
STARTING AND DRIVING

Traction Plus operation
The system is deactivated when
starting. To activate the Traction Plus
system press the A fig. 149 button.
The activation of the Traction Plus
system involves the following functions
being switched on:
inhibition of the ASR function, in
order to fully exploit the engine torque;
the differential locking effect on
the front axle, through the braking
system, to improve traction on irregular
grounds.
If the Traction Plus system is faulty, the
warning light on the instrument
panel switches on constantly.
PARKING SENSORS
These are located in the rear bumper
fig. 150 and their function is to inform
the driver, through an intermittent
beeping noise, about the presence of
obstacles behind the vehicle.
ACTIVATION
The sensors are automatically activated
when reverse is engaged. As the
obstacle behind the vehicle gets closer
to the bumper, the frequency of the
acoustic signal increases.
ACOUSTIC SIGNAL
When reverse gear is engaged an
intermittent acoustic signal is
automatically activated.
The frequency of the acoustic signal:
increases as the distance between
the vehicle and the obstacle decreases;
becomes continuous when the
distance between the vehicle and the
obstacle is less than 30 cm and stops
immediately if the distance increases;
is constant if the distance between
the vehicle and the obstacle is
unchanged;
whereas, if this situation occurs for
the side sensors, the indication will stop
after about 3 seconds to avoid, for
example, warning indications in the
event of manoeuvres alongside walls.
Detection distances
If several obstacles are detected by the
sensors, only the nearest one is
considered.
FAULT INDICATIONS
Any parking sensor faults will be
indicated when reverse is engaged by
the warning light in the instrument panel
switching on together with the
message in the multifunction display, for
versions/markets, where provided (see
chapter "Warning lights and
messages”).
