2016 Alfa Romeo MiTo catalytic converter

VERY IMPORTANT
REFUELLING
Petrol engines: only refuel with unleaded petrol with
octane rating (RON) not less than 95 in compliance with the
European Standard EN228.
Diesel engines: refuel only with diesel fuel conforming to
the European specification EN590. The use of other products
or mixtures may damage the engine beyond repair and
consequently invalidate the warranty, due to the damage
caused.
STARTING THE ENGINE
Petrol engines: make sure that the handbrake is engaged,
set the gear lever to neutral, fully depress the clutch without
depressing the accelerator, then turn the ignition key to AVV
and release it as soon as the engine has started.
Diesel engines: turn the ignition key to MAR and wait for
the warning lights
andto go out; then turn the
ignition key to AVV and release it as soon as the engine has
started.
PARKING ON FLAMMABLE MATERIAL
The catalytic converter develops high temperatures during
operation. Do not park the car on grass, dry leaves, pine
needles or other flammable material: fire hazard.
RESPECTING THE ENVIRONMENT
The car is fitted with a system that carries out a continuous
diagnosis of the emission-related components in order to help
protect the environment.
ELECTRICAL ACCESSORIES
If after having purchased the car you decide to add
accessories requiring electricity (with the risk of gradually
draining the battery), contact Alfa Romeo Authorized
Services. They can calculate the overall electric requirement
and check that the car's electric system can support the
required load.
CODE card
(for versions/markets, where provided)
Keep it in a safe place, not in the car. We recommend that
you always carry the electronic code provided on the CODE
card with you, in case you need to perform an emergency
start.
SCHEDULED SERVICING
Correct maintenance of the car is essential for ensuring that it
maintains its performance and its safety features, its
environmental friendliness and low running costs for a long
time to come.
THE OWNER MANUAL CONTAINS…
...important information, advice and warnings for correct use,
driving safety and maintenance of your car over time.
Particular attention should be paid to information marked
with the following symbols:
(personal safety)(environmental protection)(car integrity).

SPEEDOMETER (SPEED INDICATOR)
This shows the speed of the car.
REV COUNTER
This indicates the engine rpm.
FUEL LEVEL GAUGE
This shows the amount of fuel left in the fuel tank.
The warning light in the gauge switches on when there are 5 to 7 litres
of fuel remaining in the tank; if this happens, refuel as soon as
possible.
Do not travel with the fuel tank almost empty: any gaps in fuel delivery
could damage the catalytic converter.
ENGINE COOLANT TEMPERATURE
GAUGE
The needle shows the temperature of the engine coolant and starts
supplying indications when the fluid temperature exceeds approx.
50°C.
Under normal conditions, the needle assumes different positions within
the scale depending on the usage conditions.
The warning light switches on to indicate an excessive increase of the
coolant temperature; in this case, stop the engine and contact Alfa
Romeo Authorized Services.
WARNING LIGHTS ON PANEL
General warnings
On some versions, the warning light switching-on is combined with
specific messages on the display and/or acoustic warnings.
These indications are brief and precautionary and as such must not be
considered as exhaustive and/or alternative to the information
contained in this Owner's Handbook, which you are recommended to
read carefully in all cases.
Always refer to the information in this paragraph in the event of a
failure indication.
Low brake fluid level (red)
Turning the key to the MAR position illuminates the warning light, but it
should switch off after a few seconds.
The warning light (or symbol on the display) comes on when the level
of the brake fluid in the reservoir falls below the minimum level,
possibly due to leaks in the circuit.
The display will show the dedicated message.
If the warning light turns on when driving stop the car
immediately and contact Alfa Romeo Authorized Services.

should switch off after a few seconds.
If the warning light (with message + symbol displayed on some
versions) does not switch off, or if it remains lit up when driving,
contact Alfa Romeo Authorized Services.Flashing of the warning light while driving indicates the intervention of
the ESC system.
ASR failure
Turning the key to the MAR position illuminates the warning light, but it
should switch off after a few seconds.
If the warning light (or the symbol on the display) does not switch off,
or if it remains lit when driving, contact Alfa Romeo Authorized
Services.
A specific message is displayed on certain versions.
The warning light flashes while driving to indicate the intervention of
the ASR system.
Hill Holder failure
This warning light comes on, on some versions together with the
symbol and a message in the display, in the event of a fault with
the Hill Holder system.

REFUELLING THE CAR
Stop the engine before refuelling.
PETROL ENGINES
Only use unleaded petrol. The petrol octane rating (RON) must not be
lower than 95. In order to prevent damage to the catalytic converter
never introduce even the smallest amount of leaded petrol, even in the
event of an emergency.
DIESEL ENGINES
Use only diesel fuel compliant with European specification EN590. The
use of other products or mixtures may damage the engine beyond
repair and consequently invalidate the warranty, due to the damage
caused.
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 fuel are
distributed according to the season: summer type, winter type and
arctic type (cold/mountain areas). If refuelling with diesel fuel whose
features are not suitable for the temperature of use, it is advisable
to mix TUTELA DIESEL ART additive with the fuel, in the proportions
shown on the container. 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 fuel.
In this case, it is also advisable to keep the tank over 50% full.
FUEL TANK CAP
Opening
Open flap A fig. 88, pulling it outwards, hold cap B still, insert the
ignition key in the lock and turn it anticlockwise. Then turn the cap
anticlockwise and remove it.
The plug is provided with a loss prevention device C which secures it to
the flap, so it cannot be lost. Attach the cap to device D during
refuelling.
Closure
Fit the cap (complete with key) and turn it clockwise until it clicks once
or more. Then turn the key clockwise and extract it, then close the flap.
The sealing may cause a slight pressure increase in the tank. A little
breathing off, while slackening the cap is absolutely normal.
Do not place naked flames or lit cigarettes near to the
fuel filler: fire risk. Also, keep your face away from
this fuel inlet to avoid inhaling harmful fumes.

PROTECTING THE ENVIRONMENT
The following devices are used for reducing petrol fuel engine
emissions: catalytic converter, oxygen sensors and evaporation control
system
The following devices are used for reducing diesel fuel engine
emissions: oxidising catalytic converter, exhaust gas recirculation
system (EGR) and particulate filter (DPF).
DIESEL PARTICULATE FILTER (DPF)
(Diesel Particulate Filter)
(for versions/markets, where provided)
The Diesel Particulate Filter is a mechanical filter, integral to the
exhaust system, that physically traps carbon particles present in the
exhaust gases of diesel engines.
The diesel particulate filter is needed to eliminate almost all carbon
particle emissions in compliance with current/future regulations and
standards.
During standard use of the vehicle, the engine control unit records a set
of data (e.g.: travel time, type of route, temperatures, etc.) and it will
then calculate how much particulate has been trapped by the filter.Since this filter physically traps particulate, it should be periodically
regenerated (cleaned) at regular intervals by burning carbon particles.
The regeneration procedure is controlled automatically by the engine
management control unit according to the filter conditions and vehicle
use conditions.
During the regeneration there may be a limited increase in the engine
idle speed, fan activation, a limited increase in fumes and high
temperatures at the exhaust.
These are not faults; they do not impair normal car performance or
damage the environment. If the dedicated message is displayed, see
contents of "Warning lights and messages" paragraph.
The catalytic converter and particulate filter (DPF) reach
very high temperatures during operation. Therefore
do not park the car on flammable materials (grass, dry
leaves, pine needles, etc.): fire hazard.

PROCEDURE FOR DIESEL VERSIONS
Proceed as follows:
❒engage the handbrake and place the gearbox lever in neutral;
❒turn the ignition key to MAR-ON: the warning lights
and
(or the symbol on the display) on the instrument panel will
switch on;
❒wait for the warning lights (or the symbol on the display) to switch
off;
❒fully depress the clutch pedal, without touching the accelerator;
❒turn the ignition key to AVV;
warning light switches off.
Waiting too long will waste the heating work carried out by the
glow plugs. Release the key as soon as the engine starts.
If thewarning light flashes for about 1 minute after
starting or during prolonged cranking, this indicates a fault
in the glow plug preheating system. Use the car normally
if the engine starts and go to Alfa Romeo Authorized Services as soon
as possible.
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.
It is advisable not to demand maximum performance from
your car (e.g. excessive acceleration, long distances at
maximum rpm, excessively intense braking, etc.) when it is
first used.
When the engine is off, do not leave the ignition key turned
to MAR to prevent unnecessary electrical consumption from
draining the battery.
Remember that the brake servo and electromechanical
power steering are not operational until the engine
has been started, therefore much more effort than
usual is required on the brake pedal and steering wheel.
Never start the engine by pushing, towing or driving
downhill. These manoeuvres may damage the catalytic
converter.
