2015 FIAT DOBLO COMBI check engine light

Warning lights on
panelWhat it means What to do
amberINJECTION/EOBD SYSTEM FAILURE
In normal conditions, when the ignition key is turned to
MAR the warning light switches on, but it should switch
off as soon as the engine is started.
The operation of
warning light may be checked by
the traffic police using specific devices. Comply with the
laws and regulations of the country where you are
driving.13)
If the warning light stays on or switches on when driving,
it means that the injection system is not working
properly; in particular, if the warning light comes on
constantly, this indicates a malfunction in the supply/
ignition system that could cause excessive exhaust
emissions, a possible loss of performance, poor
driveability and high fuel consumption.
On some versions, the display shows the dedicated
message.
The warning light switches off if the malfunction
disappears, but it is still stored by the system.Under these conditions, you may continue
travelling at a moderate speed without
demanding excessive effort from the
engine. Prolonged use of the vehicle with
the warning light on constantly may cause
damage.
Contact a Fiat Dealership as soon as
possible.
NOTE (for petrol engine only)
If the warning light flashes, it means that the catalytic
converter may be damaged.In this case, it is necessary to release the
accelerator pedal to lower the speed of
the engine until the warning light stops
flashing. Continue the journey at moderate
speed, trying to avoid driving conditions
that may cause further flashing and
contact a Fiat Dealership as soon as
possible.

KNOWING THE INSTRUMENT PANEL

❒Fuel cut-off system failure
❒Park sensor failure.
❒Start&Stop system failureContact a Fiat Dealership as soon as possible to
have the fault fixed.
The warning light turns on and flashes to indicate a
failure of the
warning light. In this case, the
warning light may not indicate a fault in the
restraint systems.Before continuing, contact a Fiat Dealership to
have the system checked immediately.

amberDPF (PARTICULATE FILTER) CLEANING
UNDERWAY
(for versions/markets, where provided)
When the key is turned to MAR, the warning light
switches on but it should switch off after a few
seconds.
The warning light switches on constantly to inform
the driver that the DPF system needs to eliminate
the trapped pollutants (particulate) through the
regeneration process.
A dedicated message will appear on the display
when the warning light switches on (for versions/
markets, where provided).The warning light does not come on during
every DPF regeneration, but only when driving
conditions require that the driver is notified. The
warning light will switch off if the vehicle remains
in motion until regeneration has been
completed. On average, the process lasts 15
minutes.
The best conditions to complete the
regeneration process are reached by driving the
vehicle constantly at 60 km/h with engine speed
above 2000 rpm. When this warning light
comes on, it does not indicate a vehicle failure
and it should not therefore be taken to a
workshop.

KNOWING THE INSTRUMENT PANEL

IMPORTANT
22) For diesel engines, use only
diesel fuel for motor vehicles
in accordance with EN590
European specifications. The use
of other products or mixtures
may damage the engine beyond
repair and consequently invalidate
the warranty, due to the damage
caused. If you accidentally refuel
with another type of fuel, do not
start the engine, and drain the
tank. If the engine has run, even
for a very short time, you will need
to have the entire fuel supply
system emptied in addition to the
tank.
23) Do not bring naked flames or lit
cigarettes near the fuel tank filler:
fire risk. Keep your face away
from the fuel filler to prevent
breathing in harmful vapours.
SAVING FUEL
Some useful tips are given below for
fuel saving and reducing harmful
emissions of CO2 and other
pollutants (nitrogen oxides, unburnt
hydrocarbons, Particulate Matter
(PM), etc.).
PRACTICAL ADVICE
FOR REDUCING FUEL
CONSUMPTION AND
HARMFUL EMISSIONS
Vehicle conditions
❒Have checks and adjustments for
vehicle maintenancecarried out
in accordance with the “Scheduled
servicing plan”.
❒Checktyrepressure regularly, at
least once every four weeks.
Excessively low pressures will
increase consumption because
rolling resistance will be higher. In
addition, this wears the tyre more
quickly and impairs performance.
❒Only usesnow tyreswhen
the weather conditions make them
absolutely necessary. They increase
consumption and noise.❒Do not travel witha heavy load: the
weight of the vehicle (especially when
driving in town) and its geometry
greatly affect fuel consumption and
stability.
❒Removeroof racks or ski racks
after use. These accessories reduce
the vehicle's aerodynamic
penetration and have a negative
effect on fuel consumption.
❒When transporting particularly large
objects, use atrailerif possible.
❒Use the vehicle's air vents if possible:
travelling with the windows open
impairs aerodynamics.
❒Use electrical devices only for the
amount of time needed. The vehicle’s
heated rear window, additional
headlights, screen wipers and heater
fan require a considerable amount
of energy; this increases fuel
consumption (by up to +25% in an
urban cycle).
❒Air conditioning leads to higher fuel
consumption (on average up to
+30%). If the temperature outside is
not too extreme, try and use the
air vents.

STARTING AND DRIVING

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.
