check engine light Alfa Romeo MiTo 2020 Owner handbook (in English)

JUMP STARTING(versions with Start&Stop system)
125)
When jump starting, never connect the
negative lead (–) of the auxiliary battery
to the negative pole 1 fig. 111 of the car
battery, but rather to an engine/gearbox
earth point.
BUMP STARTING
Never, under any circumstances, jump
start the engine by pushing, towing or
coasting downhill.
IMPORTANT
34)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.35)Never use a fast battery-charger to
start the engine as this could damage the
electronic systems of your vehicle,
particularly the ignition and engine fuel
supply control units.
WARNING
124)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.
125)Before opening the bonnet, make sure
that the engine is off and that the ignition
key is in the STOP position. Please follow the
instructions on the decal near the front
crossmember. We recommend that you
remove the key from the ignition if other
people remain in the vehicle. The vehicle
should always be left after the key has been
removed or turned to the STOP position.
During refuelling, make sure that the engine
is off (and that the ignition key is in the STOP
position).
FUEL CUT-OFFSYSTEM
Operation
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.
The intervention of the system is
indicated by a message shown on the
display.
Carefully check the vehicle for fuel leaks,
for instance in the engine compartment,
under the vehicle or near the tank area.
126)
After a collision, turn the ignition key to
STOP to prevent the battery from
running down.
To restore the correct operation of the
car, proceed as follows:
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;

SERVICING AND MAINTENANCE

PERIODIC CHECKS
Every 1,000 km or before long trips
check and, if necessary, top up:
engine coolant, brake fluid and
windscreen washer fluid level;
tyre inflation pressure and condition;
operation of lighting system
(headlights, direction indicators, hazard
warning lights, etc.);
operation of screen wash/wipe system
and positioning/wear of windscreen/
rearscreen wiper blades
Every 3,000 km check and top up if
required: engine oil level.
IMPORTANT To find out the correct oil
quantity, always check using the dipstick.
Carry out the check with the vehicle
parked on level ground.
DEMANDING USE OF THE CAR
If the vehicle is used mainly under one of
the following conditions:
towing a trailer or caravan;
dusty roads;
short, repeated journeys (less than
7-8 km) at sub-zero outside
temperatures;
engine often idling or driving long
distances at low speeds or long periods
of inactivity;
the following checks must be carried out
more often than indicated in the
Scheduled Servicing Plan:
check front disc brake pad condition
and wear;
check cleanliness of bonnet and
luggage compartment locks, cleanliness
and lubrication of linkage;
visually inspect condition of: engine,
gearbox, transmission, pipes and hoses
(exhaust - fuel system - brakes) and
rubber elements (boots - sleeves - bushes
- etc.);
check battery charge and battery fluid
level (electrolyte);
visually inspect conditions of the
accessory drive belts;
check and, if necessary, change engine
oil and replace oil filter;
check and, if necessary, replace pollen
filter;
check and, if necessary, replace air
cleaner.

SERVICING AND MAINTENANCE

BATTERY
The battery 6 (see previous pages) does
not require the electrolyte to be topped
up with distilled water. A periodic check
carried out at an Alfa Romeo Dealership
is, however, necessary to check
efficiency.

ELECTROLYTE LEVEL

If necessary, replace the battery with
another original battery with the same
specifications. Follow the battery
manufacturer's instructions for
maintenance.
USEFUL ADVICE FOR EXTENDING THE
LIFE OF YOUR BATTERY
To avoid draining your battery and make
it last longer, observe the following
instructions:
when you park the car, ensure that the
doors, tailgate and bonnet are closed
properly, to prevent any lights from
remaining on inside the passenger's
compartment;
switch off all roof lights inside the car:
the car is however equipped with a
system which switches all internal lights
off automatically;
do not keep accessories (e.g. radio,
hazard warning lights, etc.) switched on
for a long time when the engine is not
running;
before performing any operation on
the electrical system, disconnect the
negative battery cable.
IMPORTANT If the charge level remains
under 50% for a long time, the battery is
damaged by sulphation, reducing its
capacity and efficiency at start-up.
The battery will also be more at risk of
freezing (this can happen as early as
-10°C). Refer to the "Vehicle inactivity"
paragraph in "Starting and driving"
chapter if the vehicle is left parked for a
long time.
If, after purchasing the car, you wish to
install electrical accessories which
require permanent electrical supply (e.g.
alarm, etc.) or accessories which
influence the electrical supply
requirements, contact an Alfa Romeo
Dealership, whose qualified staff will
evaluate the overall electrical
consumption.
WARNING
139)Battery fluid is poisonous and
corrosive. Avoid contact with the skin and
eyes. Keep open flames away from the
battery and do not use objects that might
create sparks: risk of explosion and fire.
140)Using the battery with insufficient
fluid irreparably damages the battery and
may cause an explosion.
141)If the vehicle must remain unused for a
long time at a very low temperature, remove
the battery and take it to a warm place, to
avoid freezing.
142)When performing any operation on the
battery or near it, always protect your eyes
with special goggles.
IMPORTANT
43)Incorrect installation of electric and
electronic devices may cause severe damage
to your car. After purchasing your vehicle, if
you wish to install any accessories (e.g.
anti-theft, radio phone, etc.), go to an Alfa
Romeo Dealership, which will suggest the
most suitable devices and advise you
whether a higher capacity battery needs to
be installed.

SERVICING AND MAINTENANCE

IMPORTANT INFORMATION AND RECOMMENDATIONS
WARNING
INTERIOR FITTINGSDo not travel with the storage compartment open: it may injure the front seat occupants in the event of an accident.
The cigar lighter gets extremely hot. Handle it carefully and make sure that children don’t use it: risk of fire and/or burns.
Do not use the ashtray as a waste paper basket: it may catch fire in contact with cigarette stubs.
ROOF RACK/SKI RACKAfter travelling for a few kilometres, check to ensure that the fixing screws for the attachments are well tightened.
Never exceed the maximum permitted loads (see chapter "Technical specifications").
Distribute the load evenly and pay attention to side winds when driving.
ELECTRIC POWER STEERINGBefore starting any servicing operation, stop the engine and remove the key from the ignition switch to operate the steering lock,
particularly when the wheels do not touch the ground. If this is not possible (for example if the key needs to be turned to MAR or the
engine must be running), remove the main fuse that protects the electric power steering.
INTERIORNever use flammable products, such as petrol ether or rectified petrol to clean the inside of the car. The electrostatic charges
which are generated by rubbing during the cleaning operation may cause a fire.
Do not keep aerosol cans in the car: they might explode. Aerosol cans must not be exposed to a temperature exceeding 50°C.
When the vehicle is exposed to sunlight, the internal temperature can greatly exceed this value.
