engine FIAT DOBLO COMBI 2017 2.G Service Manual

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. 145;
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.
129

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. 146).
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

START&STOP
SYSTEM
IN BRIEF
The Start&Stop device automatically
stops the engine each time the
vehicle is stationary and starts it
again when the driver wants to move
off.
This improves the efficiency of the
vehicle by reducing fuel consumption,
the emission of harmful gases and
noise pollution.
OPERATING MODE
Stopping the engine
WITH MANUAL GEARBOX
With the vehicle stationary, the engine
stops with the gearbox in neutral and
the clutch pedal released.
WITH ROBOTISED GEARBOX
The engine cuts out if the vehicle stops
with the brake pedal pressed.
This condition can be maintained even
if the brake pedal is not depressed, if
the gear lever is in position N.Note: The engine can only be stopped
automatically after a speed of about
10 km/h is reached, to prevent the
engine from being repeatedly stopped
when driving at walking pace.
The engine being stopped is signalled
by a fig. 147 symbol on the display,
depending on the trim level.
Restarting the engine
WITH MANUAL GEARBOX
Depress the clutch pedal to restart the
engine.
WITH ROBOTISED GEARBOX
If the gear lever is in position N, place it
in any other gear, otherwise release
the brake pedal or move the gear lever
to (+), (–) or R.MANUAL ACTIVATION
AND DEACTIVATION
The device can be activated/
deactivated by the button A fig. 148
placed on the side of the handbrake.
When the function is not active, the
button LED is on. In addition, on some
versions, additional information
concerning the deactivation or
activation of the Start&Stop system is
given through a message on the
display.

three minutes.
automatic climate control system for
adjusting the thermal comfort level or
to enable MAX-DEF function.
With a gear engaged, the engine can
be automatically restarted only by
fully depressing the clutch pedal. The
driver is asked to perform this operation
by the instrument panel warning light
fig. 147 flashing and, where provided,
the message in the display.
Note: In cases of undesired engine
stops, due for example to the clutch
pedal being released abruptly with
a gear engaged, if the Start&Stop
system is activated, the engine can be
restarted by fully depressing the clutch
pedal or by placing the gear lever in
neutral.
Note: If the clutch is not pressed, when
three minutes have elapsed since the
engine was stopped, the engine can
only be restarted using the key.
SAFETY FUNCTIONS
In engine cut-out conditions through
the Start&Stop system, if the driver
unfastens his/her seat belt and opens
the driver's door or the passenger door,
the engine can be restarted only by
using the key.The driver is notified of this condition by
a buzzer, through the instrument panel
warning light fig. 147 flashing and,
where provided, by a message in the
display.
"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. Note: In any
case, it is possible to keep the engine
running by deactivating the Start&Stop
system.

STARTING AND DRIVING

VEHICLE INACTIVITY
Versions with dummy pole fig. 150
If the vehicle is inactive, special care
must be taken to disconnect the
battery electrical power supply. This
procedure is carried out by
disconnecting the rapid release
negative terminal A from the negative
false pole B because there is a battery
status monitoring sensor D at the
negative battery pole C which should
never be disconnected except when
the actual battery is replaced.
Versions without
dummy pole fig. 151
In case of car inactivity, special
attention must be paid due 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
of the battery installed on the negative
battery pole D. This sensor should
never be disconnected from the pole
except if the battery is replaced.
98)
EMERGENCY STARTING
When jump starting, never connect the
negative lead (–) of the auxiliary battery
to the negative pole C of the vehicle
battery, but rather to either the false
pole B or to an engine/gearbox earth
point fig. 152.

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, if
the engine is stopped downhill, the engine
must be restarted by the gear lever
towards (+) or (-) without releasing the
brake pedal. For vehicles with robotised
gearbox and Hill Holder function, in case of
engine automatic stop with the car
downhill, the engine must be restarted
moving the gear lever towards (+) or (-)
without releasing the brake pedal, so that
the Hill Holder function becomes available,
as it works only with engine running.
102)If climate comfort is to be favoured,
the Start&Stop system can be deactivated,
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
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.
134
STARTING AND DRIVING

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.TPMS operation faults
The system fault is indicated by
warning light
which first flashes for
75 seconds and then stays on steadily.
This can occur in any of the following
situations:
interference caused by electronic
devices or radio frequency emissions
similar to those of the TPM sensors.
Application of tinted films which
interfere with the signals of the radio
waves.
Presence of snow or ice on the
wheels or the wheel arches.
Use of snow chains.
Use of wheels/tyres not equipped
with TPM sensors.
The space-saver wheel is not
equipped with the tyre pressure control
sensor. Therefore, the tyre pressure is
not controlled by the system.
NOTE The vehicle may be equipped
with FiX&Go Automatic tyre repair
kit, space-saver wheel or full size spare
wheel (with or without original TPMS
sensor to measure tyre pressure).
After the punctured tyre has been
repaired with the original tyre sealant
contained in the FiX&Go Automatic tyre
repair kit, the previous condition must
be restored, so that the
warning
light is off during normal driving.
135

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. 153.
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.
Deactivating the
function
The device can be switched off by the
driver in the following ways:
by pressing the brake pedal when
the device is adjusting the speed:
by pressing the clutch pedal when
the device is adjusting the speed;
by pressing button B fig. 153 when
the device is adjusting the speed (for
versions/markets, where provided);
by pressing the accelerator pedal (in
this case the system is not actually
turned off but the acceleration request
takes priority; the cruise control remains
activated, without the need to the
press button B fig. 153 to restore the
previous conditions once the
acceleration is over).
The device is automatically switched off
in the following cases:
if the ABS or ESC systems intervene
with the vehicle speed below the
set limit
in the event of system failure.
WARNING
112)When travelling with the device active,
never move the gear lever to neutral.
113)In the event of device faults or failures,
turn the ring nut A to OFF and contact a
Fiat Dealership.
138
STARTING AND DRIVING

TRACTION PLUS
SYSTEM
(for versions/markets, where provided)
Traction Plus is a driving aid, useful
for setting off in poor grip conditions
(snow, ice, mud, etc.) which allows the
drive force to be distributed in the
best way over the front axle when one
wheel is slipping.
Traction Plus acts by braking the
wheels with poor grip (or those slipping
more than the others), thereby
transferring the drive force to those
which have greater grip on the ground.
This function can be activated manually
by pressing the A fig. 154 button on
the control panel and operates under
50 km/h. When this speed is exceeded,
it is automatically deactivated and it is
reactivated again when the speed
falls below 50 km/h.Traction Plus operation
The system is deactivated when
starting. To activate the Traction Plus
system press the A fig. 154 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. 155 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;
154F0V0575
155F0V0077
139

If they are open, they can cause the
system to send false signals: always
close the rear doors.
Do not apply stickers to the sensors.
WARNING
114)The sensors must be clean of mud,
dirt, snow and ice in order for the system
to work. Be careful not to scratch or
damage the sensors while cleaning them.
Avoid using dry, rough or hard cloths.
The sensors must be washed using clean
water, with the addition of car shampoo
if necessary. When using special washing
equipment such as high pressure jets or
steam cleaning, clean the sensors very
quickly keeping the jet more than 10 cm
away.
115)Parking manoeuvres, however, are
always the driver’s responsibility. While
carrying out these manoeuvres, always
make sure that no people (especially
children) or animals are in the area
concerned. The parking sensor is designed
to assist drivers, who must still never
allow their attention to lapse during
potentially dangerous manoeuvres even if
performed at low speed.
REFUELLING THE
VEHICLE
PETROL ENGINES
Only use unleaded petrol, with an
octane number (R.O.N.) not lower than
95.
IMPORTANT An inefficient catalytic
converter leads to harmful exhaust
emissions, thus contributing to air
pollution.
IMPORTANT Never use leaded petrol,
even in small amounts or in an
emergency, as this would damage the
catalytic converter beyond repair.
DIESEL ENGINES
Operation at low temperatures
If the outside temperature is very low,
the diesel thickens due to the formation
of paraffin clots with consequent
defective operation of the fuel supply
system.In order to avoid these problems,
different types of Diesel are distributed
according to the season: summer
type, winter type and Arctic type (cold,
mountain areas). If refuelling with diesel
whose specifications are not suitable
for the usage temperature, it is
advisable to mix PETRONAS
DURANCE DIESEL ART additive in the
proportions shown on the container
with the fuel. Pour the additive into the
tank before the fuel.
When using or parking the vehicle for a
long time in the mountains or cold
areas, it is advisable to refuel using
locally available diesel fuel.
In this case, it is also advisable to keep
the tank over 50% full.
22)
TANK CAPACITY
To ensure that you fill the tank
completely, top up twice after the first
click of the fuel supply gun. Further
top-ups could cause faults in the fuel
feeding system.
FUEL TANK CAP
Opening
1) Open the flap A fig. 156 by pulling it
outwards, keep the cap B still, insert
the ignition key in the lock and turn
it anticlockwise.
