2015 FIAT DOBLO COMBI engine

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
Engine stopping mode
WITH MANUAL GEARBOX
With the vehicle stationary, the
engine stops with the gearbox in
neutral and the clutch pedal
released.WITH ROBOTIZED 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 the fig. 140 icon on the
display, depending on the trim
level.Engine restarting
mode
WITH MANUAL GEARBOX
Depress the clutch pedal to restart
the engine.
WITH ROBOTIZED 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 via button A fig. 141
located to the side of the
handbrake.
The deactivation is signalled when
the LED on the button switches on.
In addition, on the versions where
provided, additional information
concerning the deactivation or
activation of the Start&Stop is given
through a message in the display.

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 fig. 140
warning light flashing in the
instrument panel 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. 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. 142, where
provided, coming on with an
information message and the
system failure symbol B fig. 142 in
the control panel. In this case,
contact a Fiat Dealership.VEHICLE INACTIVITY
Versions with dummy
pole fig. 143
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

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.
85) 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)
86) 87) 88) 89) 90) 91) 92) 93) 94)
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.
144
STARTING AND DRIVING

❒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.
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.
145

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. 146 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. 146
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
95) When travelling with the device
active, never move the gear lever
to neutral.
96) In the event of device faults or
failures, turn the ring nut A to
OFF and contact a Fiat
Dealership.
149

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. 147
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. 147 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. 148 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.
