2021 Alfa Romeo MiTo warning lights

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

WATER IN DIESEL FILTER (Diesel versions)
The warning light switches on constantly when driving to indicate
the presence of water in the diesel filter.
15)
DPF CLEANING (particulate trap) in progress (diesel versions
with DPF only)
The warning light switches on when the ignition key is turned to
MAR, but it should switch off after a few seconds. The warning
light switches on constantly to indicate that the DPF system
needs to eliminate the trapped pollutants (particulate) through
the regeneration process.
The warning light does not come on during every DPF
regeneration, but only when driving conditions require that the
driver is notified. To turn off the warning light, keep the car in
motion until the regeneration process is over.
On average, the process lasts 15 minutes. Optimal conditions for
completing the process are achieved by travelling at 60 km/h
with engine speed above 2000 rpm.
When this warning light switches on, it does not indicate a vehicle
failure and thus it should not be taken to a workshop.

TPMS SYSTEM
Low tyre pressure
The warning light (or symbol on the display) switches on (on some
versions together with a message on the display) (together with
an acoustic signal) if the pressure in one or more tyres drops
below a preset threshold.
In this way the TPMS warns the driver that one or more tyres may
be dangerously flat and liable to puncture.In any situation in which the message on the
display is "See manual", it is ESSENTIAL to refer
to the contents of the "Wheels" paragraph in the
"Technical specifications" section, strictly
complying with the indications that you find
there.
IMPORTANT Do not continue driving with one or
more flat tyres as handling may be
compromised. Stop the vehicle, avoiding sharp
braking and steering. Replace the wheel
immediately with the spare wheel (where
provided) or carry out a prompt repair using the
dedicated kit (see the paragraph on “Replacing a
wheel” in chapter “In an emergency”) and contact
Alfa Romeo Dealership as soon as possible.
TPMS failure
This warning light switches on (on some versions together with a
message on the display) when a TPMS fault is detected.
Should one or more wheels be fitted without sensors, the display
will show a warning message until initial conditions are restored.Contact an Alfa Romeo Dealership as soon as
possible.
Check tyre pressure
The warning light switches on (on some versions together with a
message in the display) to indicate that the tyre pressure is below
the value recommended to guarantee long tyre life and low fuel
consumption. It may also indicate a slow loss of pressure.
Should two or more tyres be in the condition mentioned above,
the display will show the indications corresponding to each tyre in
sequence. In this case it is advisable to restore the correct
pressure value

EOBDSYSTEM (European On
Board Diagnosis)
(where provided)
Operation
The EOBD system (European On Board
Diagnosis) carries out a continuous
diagnosis of the components of the car
related to emissions.
It also alerts the driver, by switching on
the warning light
on the instrument
panel, together with a message on the
display, when these components are no
longer in peak condition (see “Warning
lights and messages” paragraph in the
"Knowing the instrument panel" chapter).
The aim of the EOBD system (European
On Board Diagnosis) is to:
monitor the efficiency of the system;
indicate an increase in emissions;
indicate the need to replace damaged
components.
The vehicle also has a connector, which
can interface with appropriate tools, that
makes it possible to read the error codes
stored in the electronic control units
together with a series of specific
parameters for engine operation and
diagnosis. This check can also be carried
out by the traffic police.
IMPORTANT After eliminating a fault, to
check the system completely, the Alfa
Romeo Dealership is obliged to run tests
and, if necessary, road tests which may
also require a long journey.

KNOWING THE INSTRUMENT PANEL

SBR SYSTEM (Seat Belt
Reminder)
It consists of an acoustic warning which,
switching on the
warning lights in the
trim located on the fig. 46 internal rear
view mirror, warns passengers in the
front and rear seats that their seat belts
are not fastened.
For long-term deactivation of the SBR
system, contact a Alfa Romeo
Dealership.
The SBR system can be reactivated at
any time through the Setup Menu only
(see “Menu Items” in “Knowing your
vehicle” section).
The warning lights may be red or green
and operate as follows:
1 = front left seat (driver status for
left-hand drive versions)
2 = rear left seat (passenger);
3 = rear centre seat (passenger)
4 = rear right seat (passenger);
5 = front right seat (passenger status
for left-hand drive versions).
NOTE On versions equipped with sport
front seats, the indication of passenger
side seat belt fastened (warning light
1 for right-hand drive versions or warning
light 5 for left-hand drive versions) will
never be displayed.
FRONT SEATS (warning light 1 = driver
and 5 = passenger)
Driver
If the driver is the only occupant and the
seat belt is not fastened, when 20 km/h
is exceeded or when travelling at a speed
from 10 to 20 km/h for longer than
5 seconds, a buzzer sequence will be
started (front seats) consisting of a tone
for 6 seconds followed by a 90 second
beep.The warning light will blink.
The warning lights will stay on constantly
at the end of the cycle until the engine is
stopped. The acoustic signal will be
interrupted immediately when the
driver’s seat belt is fastened and the
warning light will turn green.
The reminder cycle (acoustic and visual)
will be repeated as described above and
the red warning light will flash if the seat
belt is unfastened again while travelling.Passenger
A similar solution applies for the front
passenger, with the difference that the
warning light turns green and the signal is
interrupted also when the passenger
leaves the car.
It both front seat belts are unfastened
while the vehicle is travelling a few
seconds apart, the acoustic indication
will refer to the most recent event and
the two warning lights will proceed with
the visual indication independently.
REAR SEATS (warning light 2, 3 and 4)
The reminder cycle is run only when any
seat belt is unfastened (red blinking).
In this condition, the warning light for the
seat belt which has been unfastened will
start flashing red for approximately
30 seconds. An acoustic signal is also
emitted.
The visual indication (blinking red) will
start and end independently for each
warning light if several seat belts are
unfastened. The warning light will
become green when the relevant seat
belt is fastened again.
After about 30 seconds from the last
indication, the warning lights for rear
seats will switch off, irrespective of the
belt conditions (red or green).
