engine Alfa Romeo MiTo 2016 Workshop Manual

IMPORTANT
Do not wash the seats with water or pressurised steam (by hand or at
automatic seat washing stations).
The front and/or side bags may activate in the event of sharp knocks
to the underbody of the car (e.g. impact with steps, pavements,
potholes or road bumps etc.).
When the airbag deploys it emits a small amount of dust: the dust is
harmless and does not indicate the beginning of a fire. The dust may
irritate the skin and eyes however: in this case, wash with neutral soap
and water.
All operations on airbags (inspection, repair and replacement) must be
carried out by Alfa Romeo Authorized Services.
If the car is to be scrapped, contact Alfa Romeo Authorised Services to
have the airbags deactivated.
Pretensioners and airbags are deployed in different ways, according to
the type of impact. Failure to deploy of one of the devices does not
necessarily indicate a system malfunction.
If thewarning light does not switch on when the
key is turned to MAR-ON, or stays on while driving (on
some versions together with a message on the
display) there may be a fault in the restraint systems. In this
case, airbags or pretensioners may not be activated in the case
of an accident or (in a lesser number of cases) they may be
activated incorrectly. Before proceeding, contact Alfa Romeo
Authorised Services to have the system checked immediately.
Do not travel carrying objects in your lap, in front of
your chest or between your lips (pipe, pencils, etc.):
they could cause severe injury if the airbag is
deployed.
If the car has been subject to theft, attempted theft,
vandalism, or flooding, have the airbag system
inspected at Alfa Romeo Authorised Services.
When the ignition key is in and turned in the MAR-ON
position and the engine is off, the airbags may deploy
if the car is crashed by another moving vehicle.
Therefore, even if the car is stationary, when an active passenger
airbag is fitted, DO NOT install rear facing child restraint systems
on the front passenger seat. Deployment of the airbag following
an impact could cause fatal injuries to the child. Therefore,
always deactivate the passenger airbag when a rear facing child
restraint system is installed on the front passenger seat. The front
passenger seat must also be positioned back as far as possible
in order to avoid the child restraint system from coming into
contact with the dashboard. Immediately reactivate the
passenger airbag as soon as the child restraint system has been
removed. Also remember that, if the key is turned to STOP, none
of the safety devices (airbags or pretensioners) will be deployed
in the event of collision. Non-deployment in such cases does not
indicate a system malfunction.

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.

WARMING UP THE ENGINE JUST
AFTER IT HAS STARTED
Proceed as follows:
❒drive off slowly, letting the engine turn at medium revs and without
accelerating abruptly;
❒do not demand maximum performance for the first few kilometres. It
is advisable to wait until the engine coolant temperature indicator
starts moving.
STOPPING THE ENGINE
Turn the ignition key to STOP while the engine is idling.
IMPORTANT After a demanding drive, before turning the engine off
you should allow it to idle to allow the temperature in the engine
compartment to decrease.
A quick burst on the accelerator before stopping the engine
serves absolutely no practical purpose. It wastes fuel and
is especially damaging to turbocharged engines.
PARKING
Switch off the engine and pull up the handbrake. Engage a gear (1stif
the car is facing uphill or reverse if it is facing downhill) and leave
the wheels steered to one side.
If the car is parked on a steep slope block the wheels with a wedge or
stone. Always remove the ignition key when leaving the car.
Never leave children unattended in the car. Always
remove the key from the ignition when leaving the car
and take it with you.

SAVING FUEL
Here are some suggestions which can help you to save fuel and lower
harmful emissions.
GENERAL CONSIDERATIONS
Car maintenance
Have checks and adjustments carried out in accordance with the
“Scheduled Servicing Plan” (see chapter “Maintenance and care”).
Ty r e s
Check the tyre pressure at least once every 4 weeks: if the pressure is
too low, consumption levels increase as resistance to rolling is higher.
Unnecessary loads
Do not travel with an overloaded boot. The weight of the car and its
arrangement greatly affect fuel consumption and stability.
Roof rack/ski rack
Remove the roof rack or the ski rack from the roof after use. These
accessories lower aerodynamic penetration and adversely affect
consumption levels. It is better to use a trailer to transport particularly
bulky objects.
Electrical devices
Only use electrical devices for the time needed. The heated rear
window, additional headlights, windscreen wipers and heater fan
require a considerable amount of energy; increasing the current uptake
increases fuel consumption (by up to +25% in an urban cycle).Climate control system
Using the climate control system will increase consumption: use the air
vents when the external temperature allows it.
Devices for aerodynamic control
The use of non-certified devices for aerodynamic control may adversely
affect air drag and fuel consumption.
DRIVING STYLE
Starting
Do not warm up the engine at low or high revs when the vehicle is
stationary; this causes the engine to warm up more slowly, thereby
increasing fuel consumption and emissions. It is therefore advisable to
move off immediately, slowly, avoiding high speeds: in this way the
engine will warm up more quickly.
Unnecessary actions
Avoid revving up when at traffic lights or before switching off the
engine. The latter action, like double-declutching, is unnecessary and
causes increased fuel consumption and pollution.
Gear selection
Use a higher gear when traffic and road conditions allow it. Using a
low gear for faster acceleration will increase consumption. In the same
way improper use of a high gear increases consumption, emissions
and engine wear.

INDEX

Maximum speed
Fuel consumption considerably increases as speed increases. Keep
your speed as even as possible, avoiding unnecessary braking and
acceleration which cause excessive fuel consumption and increased
emissions.
Acceleration
Accelerating violently severely affects consumption and emissions:
acceleration should be gradual and should not exceed the maximum
torque.
CONDITIONS OF USE
Cold starting
Short distances and frequent cold start-ups will prevent the engine from
reaching optimal running temperature. This results in a significant
increase in consumption levels (from +15 to +30% on the urban cycle)
and emissions.
Traffic and road conditions
High fuel consumption is caused by heavy traffic, for instance when
travelling in a queue with frequent use of low gears or in large towns
with many traffic lights. Winding mountain roads and rough road
surfaces also adversely affect consumption.
Stops in traffic
During prolonged stops (e.g. level crossings) switch the engine off.
TOWING TRAILERS
IMPORTANT
The vehicle must be provided with a type-approved tow hook and
adequate electrical system to tow caravans or trailers. Installation must
be carried out by a specialist.
Fit any specific and/or additional rear view mirrors as specified by the
Highway Code.
Remember that, when towing a trailer, steep hills are harder to climb,
braking distances increase and overtaking takes longer relative to
the overall weight of the trailer.
Engage a low gear when driving downhill, rather than constantly using
the brake.
The weight of the trailer reduces the load capacity of the car by the
same amount. Consider the weight at full load, including accessories
and luggage, to make sure you do not exceed the maximum towable
weight (shown in the registration document).
Respect the speed limits specific to each country for vehicles towing
trailers. In any case do not exceed 100 km/h.

SNOW CHAINS
The use of snow chains should be in compliance with local regulations.
The snow chains may be applied only onto the front wheel tyres (drive
wheels).
Check the tension of the snow chains after the first few metres have
been driven.
Use reduced size snow chains: on all versions, for 195/55 R16" and
205/55 R16" size tyres use low-clearance snow chains with a
maximum projection beyond the tyre profile of 9 mm.
IMPORTANT The space-saver wheel cannot be fitted with snow chains.
If a front (drive) wheel is punctured and snow chains must be used,
you must remove a normal wheel from the rear and replace this one
with the space-saver wheel. In this way, with two normal drive wheels,
it is possible to use snow chains.
Keep your speed down when snow chains are fitted; do not
exceed 50 km/h. Avoid potholes, steps and pavements
and avoid driving long distances on roads not covered with
snow to avoid damaging the car and the roadbed.
STORING THE CAR
If the car is to be left inactive for longer than a month, the following
precautions should be noted:
❒park the vehicle in a dry, covered and, if possible, ventilated area;
engage a gear and check that the handbrake is not engaged;
❒disconnect the negative battery terminal and check the battery
charge. Repeat this check once every three months during storage;
❒if you have not disconnected the battery, check the battery charge
every thirty days;
❒clean and protect the painted parts using protective wax;
❒clean and protect the shiny metal parts using special compounds
available commercially;
❒sprinkle talcum powder on the windscreen and rear window wiper
rubber blades and lift them off the glass;
❒slightly open the windows;
❒cover the car with a cloth or perforated plastic sheet. Do not use
compact plastic sheets which do not allow humidity to evaporate
from the surface of the car.
❒inflate tyres to +0.5 bar above the standard specified pressure and
check it at intervals;
❒do not drain the engine cooling system.
IMPORTANT After turning the ignition key to STOP, wait at least 1
minute before disconnecting the battery power supply.

IN AN EMERGENCY
In an emergency we recommend that you call the freephone number found in the Warranty Booklet. You can also
consult www.alfaromeo.com to find your nearest Alfa Romeo Authorized Services.
STARTING THE ENGINE
If thewarning light on the instrument panel remains on constantly,
contact Alfa Romeo Authorized Services immediately.
JUMP STARTING
If the battery is flat, the engine may be started using an auxiliary
battery with the same capacity or a little higher than the flat one.
Proceed as follows to start the vehicle:
❒connect the positive terminals (+ sign near the terminal) of the two
batteries with a jump lead fig. 115;❒with a second cable, connect the negative terminal(–)ofthe
auxiliary battery to an earthing point
on the engine or the
gearbox of the car to be started;
❒start the engine; afterwards, follow the sequence above in reverse
order to remove the cables.
For versions with Start&Stop system, to carry out the jump starting
procedure, refer to the paragraph “Start&Stop system” in the “Getting
to know your car” section.
Contact Alfa Romeo Authorized Services if you cannot start the engine
after several attempts.
IMPORTANT Never connect the negative terminals of the two batteries
directly! If the auxiliary battery is installed on another car, prevent
accidental contact between metallic parts of the two cars.
Never use a fast battery-charger to start the engine as this
could damage the electronic systems of your car,
particularly the ignition and fuel supply control units.

This starting procedure must be performed by expert
personnel because incorrect actions could cause
electrical discharge of considerable intensity.
Furthermore, battery fluid is poisonous and corrosive: avoid
contact with skin and eyes. Keep naked flames and lighted
cigarettes away from the battery and do not cause sparks.
BUMP STARTING
Never start the engine by pushing, towing or coasting downhill.
REPLACING A WHEEL
GENERAL INSTRUCTIONS
The car is equipped with the “Fix&Go Automatic Kit”: see the
paragraph “Fix&Go Automatic Kit” for how to use this device.
As an alternative to the “Fix&Go Automatic Kit” the car may be
equipped with a space-saver wheel: see the instructions on the
following pages for changing the tyre.
The spare wheel is specific for your car. Do not use it
on cars of different models. Do not use spare wheels of
different models on your car. The space-saver wheel
must only be used in case of emergency. It must only be used for
the distance necessary to reach a service point and the car speed
must not exceed 80 km/h. The space-saver wheel has an orange
sticker that summarises the main cautions for use and limitations.
Never remove or cover the label. Never apply any hub cap to
the space-saver spare wheel.
Alert other drivers that the car is stationary in
compliance with local regulations: hazard warning
lights, warning triangle, etc. Any passengers on board
should leave the car, especially if it is heavily laden. Passengers
should stay away from on-coming traffic while the wheel is
being changed. In case of steep slopes or rough slopes, place
wedges or other materials suitable to stop the vehicle under the
wheels.

The vehicle's driving characteristics will be modified
with the space-saver wheel fitted. Avoid violent
acceleration and braking, sharp steering and fast
cornering. The total life of a space-saver wheel is approximately
3,000 km, after which it must be replaced by another wheel of
the same type. Never attempt to fit a conventional tyre on a rim
designed for use as a space-saver wheel. Repair and refit the
standard wheel as soon as possible. Two or more space-saver
wheels should never be used together. Do not grease the threads
of bolts before fitting them: they might slip out.
The jack provided is only intended to be used for
replacing tyres on the vehicle with which it is supplied,
or on same-model vehicles. Never use the jack for
other purposes, such as lifting other car models. Never use it for
repair operations under the vehicle. Incorrect positioning of the
jack may cause the car to fall. Do not use the jack for loads
higher than those shown on the label. Never install snow chains
on the small spare wheel; if a front tyre (driving wheel) is
punctured and you need to use snow chains, use a standard
wheel from the rear axle and install the small spare wheel on the
rear axle. In this way, with two normal front drive wheels, it is
possible to use snow chains.
Incorrectly fitting the hubcap may cause it to fall off
when the vehicle is in motion. Never tamper with the
inflating valve. Never introduce tools of any kind
between rim and tyre. Regularly check the inflation pressure of
the tyres and space-saver wheel (see chapter "Technical
specifications").
JACK
Please note that:
❒the jack weight is 1.76 kg;
❒the jack requires no adjustment;
❒the jack cannot be repaired and in the event of a fault it must be
replaced by another original one;
❒no tool other than its cranking device may be fitted on the jack.
To change a wheel proceed as follows:
❒stop the car in a position that is not dangerous for oncoming traffic
where you can change the wheel safely. The ground must be flat
and sufficiently compact;
❒switch off the engine, pull up the handbrake and engage 1
agear or
reverse; put on the high visibility jacket (required by law) before
leaving the vehicle;
❒open the luggage compartment, pull tab A fig. 116 and lift up the
mat;
