exhaust Alfa Romeo MiTo 2017 Owner's Manual

WARNING LIGHTS AND MESSAGES
IMPORTANT The warning light switches on in the instrument panel together with a dedicated message and/or acoustic signal when
applicable. These indications are indicative and precautionary and as such must not be considered as exhaustive and/or alternative
to the information contained in the Owner Handbook, which you are advised to read carefully in all cases. Always refer to the
information in this section in the event of a failure indication.
IMPORTANT Failure indications displayed are divided into two categories: very serious and less serious failures. Serious faults are
indicated by a repeated and prolonged warning "cycle". Less serious faults are indicated by a warning "cycle" with a shorter duration.
The display cycle of both categories can be interrupted. The instrument panel warning light will stay on until the cause of the
malfunction is eliminated.
WARNING LIGHTS ON INSTRUMENT PANEL
Warning lights on
panelWhat it means What to do
LOW BRAKE FLUID/HANDBRAKE ENGAGED
The warning light switches on when the key is turned to
MAR-ON, but it should switch off after a few seconds.
Low brake fluid level
The warning light (or symbol on the display) switches on
when the level of the brake fluid in the reservoir falls
below the minimum level, possibly due to leaks in the
circuit.Restore the brake fluid level, then check that the warning
light has switched off.
If the warning light stays on, contact an Alfa Romeo
Dealership.
Handbrake engaged
The warning light (or symbol on the display) switches on
when the handbrake is engaged. If the car is moving an
acoustic signal is also emitted.Release the handbrake, then check that the warning light
has switched off.
If the warning light (or symbol on the display) stays on,
contact an Alfa Romeo Dealership.

KNOWING THE INSTRUMENT PANEL

Warning lights on
panelWhat it means What to do
INJECTION/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 the
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.14)
If the warning light remains on or switches on whilst driving, it
means that the injection system is not working properly. The
warning light on constantly signals a malfunction in the
supply/ignition system which could cause high exhaust emissions,
a possible loss of performance, poor driveability and high
consumption.
The warning light goes out after the fault disappears: the
indication is stored in the system.Under these conditions, the vehicle can continue
travelling at moderate speed without
demanding excessive effort from the engine.
Prolonged use of the car with the warning light
on constantly may cause damage.
Contact an Alfa Romeo Dealership as soon as
possible.
Petrol engines only
If the warning light flashes, it means that the catalytic converter
may be damaged.In this case, 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 an Alfa Romeo Dealership as soon as
possible.
GLOW PLUG HEATING/GLOW PLUG HEATING FAILURE (diesel
versions)
This warning light switches on when the key is turned to MAR. It
will switch off as soon as the heater plugs have reached a preset
temperature. The engine can be started as soon as the warning
light switches off.
WARNING In mild or high temperature conditions, the warning
light comes on for a very short time only.
Glow plug preheating failure
The warning light will flash to indicate a failure in the glow plug
preheating system.Contact an Alfa Romeo Dealership as soon as
possible.

KNOWING THE INSTRUMENT PANEL

WARNING
23)If thewarning light does not switch on when the ignition device is moved to ON or if it stays on when driving (together with the message on
the display), there might be a fault in the restraint systems; in this case, the airbags or pretensioners may not deploy in the event of an accident or,
in a lower number of cases, they could deploy erroneously. Before proceeding, contact an Alfa Romeo Dealership to have the system checked
immediately.
24)A fault with the warning light
is signalled by illumination of the iconon the instrument panel display and by the flashing of passenger
airbag disabled warning light on the rearview mirror. In addition, the airbag system automatically disables the passenger side airbag (where
provided). In this case, the warning light may not indicate any faults with the restraint systems. Before proceeding, contact an Alfa Romeo
Dealership to have the system checked immediately.
25)If the warning light comes on, the exhausted engine oil should be changed as soon as possible, never drive more than 500 km from the first
switching-on of this warning light. Failure to observe the above may result in severe damage to the engine and invalidate the warranty. Remember
that when this warning light comes on, it does not mean that the level of engine oil is low, so if it flashes you must not top up the engine oil.
26)If the warning light flashes with the car in motion, contact an Alfa Romeo Dealership.
27)Always drive at a speed appropriate to the traffic conditions, the weather and traffic regulations. The engine may be switched off even if the
warning light is on: repeated interruptions of the regeneration process could cause an early deterioration of engine oil. For this reason it is
always advisable to wait for the symbol to go off before turning off the engine, following the instructions above. Do not complete the DPF
regeneration process when the vehicle is stopped.
IMPORTANT
13)If thewarning light switches on when driving, stop the engine immediately and contact an Alfa Romeo Dealership.
14)If, turning the ignition device to MAR, the warning lightdoes not turn on or if it turns on steadily or flashing when travelling (on some
versions together with the message on the display), contact an Alfa Romeo Dealership as soon as possible.
15)The presence of water in the fuel system circuit may cause severe damage to the injection system and irregular engine operation. If the
symbol is displayed contact an Alfa Romeo Dealership as soon as possible to bleed the system. If the above indications come on immediately
after refuelling, water has probably been introduced into the tank: stop the engine immediately and contact an Alfa Romeo Dealership.
