2018 Alfa Romeo MiTo check engine

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;

“VELOCE” versions: remove cap 1 by
pressing on the upper part, take tow hook
2 from its housing in the tool support and
screw it in fully on the threaded pin.
WARNING
127)For versions with key without remote
control, before towing, turn the ignition key
to MAR and then to STOP without removing
it. The steering column will automatically
lock when the key is removed and the wheels
cannot be steered. Also check that the
gearbox is in neutral (on versions equipped
with automatic transmission, check that the
gear lever is in N position). For versions with
electronic key, move the ignition device to
MAR and then to STOP, without opening the
door.128)The brake servo and the
electromechanical power steering will not
work while the vehicle is being towed. You
will therefore need to apply more force on
the brake pedal and steering wheel. Do not
use flexible ropes when towing, and avoid
jerky movements. During towing, make sure
that the trailer hitch does not damage any
components it is touching. When towing the
car, you must comply with all specific traffic
regulations and adopt an appropriate
driving behaviour. Do not start the engine
while towing the car. Before tightening the
ring, clean the threaded housing thoroughly.
Make sure that the ring is fully screwed into
the housing before towing the car.
129)The front and rear tow hooks should be
used only for emergencies on the road. You
are allowed to tow the vehicle for short
distances using an appropriate device in
accordance with the highway code (a rigid
bar), to move the vehicle on the road in
readiness for towing or transport via a
breakdown vehicle. Tow hooks MUST NOT be
used to tow vehicles off the road or where
there are obstacles and/or for towing
operations using cables or other non-rigid
devices. In compliance with the above
conditions, towing must take place with the
two vehicles (one towing, the other towed)
aligned as much as possible along the same
centre line.

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

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;

ENGINE OIL
132)
38) 39)
2)
Check that the oil level is between the
MIN and MAX references on the dipstick
1. If the level of the oil is close to or below
the MIN mark, add oil via the filler fitting
2 until the MAX mark is reached.
1.4 Petrol / 1.4 Turbo Petrol/LPG /
1.4 Turbo Multi Air / 1.3 JTD
M-2versions: pull the engine oil dipstick 1,
clean it with a lint-free cloth and insert
it again. Extract it again and check that
the level is between the MIN and MAX
marks on the dipstick.
Turbo TwinAir versions: engine oil
dipstick 1 is integral with the cap 2.
Unscrew the cap, clean the dipstick with a
lint-free cloth, reinsert the dipstick and
screw the cap back on. Unscrew the plug
again and check that the engine oil level is
between the MIN and MAX marks on the
dipstick.
Engine oil consumption
The maximum engine oil consumption is
usually 400 grams every 1000 km. When
the car is new, the engine needs to be run
in; therefore the engine oil consumption
can only be considered stabilised after
the first 5000 - 6000 km.
ENGINE COOLANT FLUID
132)
40)
If the level is too low, unscrew the cap
3 of reservoir and add the fluid described
in the "Technical Specifications" chapter.
WINDSCREEN / REAR WINDOW
WASHING FLUID
134) 135)
If the level is too low, raise the reservoir
cap 4 and add the fluid described in the
"Technical Specifications" chapter.
BRAKE FLUID
136) 137)
41)
Check that the fluid is at the max. level. If
the fluid level in the reservoir is too low,
undo the reservoir cap 5 and add the fluid
described in the "Technical
Specifications" chapter.
ALFA TCT ACTIVATIONSYSTEM OIL(where provided)
3)
The transmission control oil level should
only be checked at an Alfa Romeo
Dealership.
IMPORTANT
37)Be careful not to confuse the various
types of fluids while topping up: they are not
compatible with each other! Topping up with
an unsuitable fluid could severely damage
your vehicle.
38)The oil level must never exceed the MAX
reference.
39)Do not add oil with specifications other
than those of the oil already in the engine.
40)Use a fluid of the same type as that
already present in the reservoir for any
topping up of the engine cooling system. The
fluid cannot be mixed with other types of
antifreeze fluids. In the event of topping up
with an unsuitable product, under no
circumstances start the engine and contact
an Alfa Romeo Dealership.
41)Prevent brake fluid, which is highly
corrosive, from coming into contact with
painted parts. Should it happen, immediately
wash with water.
WARNING
130)Never smoke while working in the
engine compartment: gas and inflammable
vapours may be present, with the risk of fire.
131)Be very careful when working in the
engine compartment when the engine is hot:
you may get burned. Do not get too close to
the radiator cooling fan: the electric fan may
start; danger of injury. Scarves, ties and
other loose clothing might be pulled by
moving parts.
