2021 Alfa Romeo MiTo ECU

The following conditions may influence
the performance of the parking
assistance system:
reduced sensor sensitivity and a
reduction in the parking assistance
system performance could be due to the
presence on the surface of the sensor of:
ice, snow, mud, thick paint
The sensors may detect a
non-existent obstacle (echo interference)
due to mechanical interference, for
example when washing the car, in rain
(strong wind), hail.
The signals sent by the sensors can
also be altered by the presence of
ultrasonic systems (e.g. pneumatic brake
systems or pneumatic drills) near the
vehicle.
sensor performance can also be
influenced by the position of the sensors.
For example by a change in the ride
setting (caused by the wear of the shock
absorbers, suspension), overloading the
car and carrying out specific tuning
operations that require the car to be
lowered;
The detection of obstacles at the top
part of the car may not be guaranteed
because the system detects obstacles
that could cause an impact with the car in
the bottom part.
IMPORTANT
26)The sensor must be free of mud, dirt,
snow or ice in order for the system to work.
Be careful not to scratch or damage the
sensors while cleaning them. Avoid using dry,
rough or hard cloths. The sensors must be
washed using clean water, with the addition
of vehicle shampoo if necessary. When using
special washing equipment such as high
pressure jets or steam cleaning, clean the
sensors very quickly keeping the jet more
than 10 cm away.
WARNING
103)Only have the bumpers repainted or
any retouches to the paintwork in the area of
the sensors carried out by an Alfa Romeo
Dealership. Incorrect paint application could
affect the operation of the parking sensors.
104)Parking and other dangerous
manoeuvres are, however, always the
driver’s responsibility. While carrying out
these manoeuvres, always make sure that
no people (especially children) or animals are
in the area concerned. The parking sensors
are an aid for the driver, but the driver must
never allow their attention to lapse during
potentially dangerous manoeuvres, even
those executed at low speeds.
TOWING TRAILERS
105) 106)
IMPORTANT NOTES
The car must be provided with a
type-approved tow hook and adequate
electric system to tow caravans or
trailers. Installation must be carried out
by a specialist.
Install any specific and/or additional door
mirrors as specified by the Highway
Code.
Remember that when towing a trailer,
steep hills are harder to climb, the
braking spaces increase and overtaking
takes longer depending on the overall
weight.
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).
Do not exceed the speed limits specific
to each country you are driving in, in the
case of vehicles towing trailers. In any
case do not exceed 100 km/h.

INSTALLING A TOW HOOK
Contact an Alfa Romeo Dealership to
install a tow hook.
WARNING
105)The ABS with which the car is equipped
will not control the braking system of the
trailer. Particular caution is therefore
required on slippery roads.
106)Do not, under any circumstances,
modify the vehicle's braking system to
control the trailer breaking system. The
towing braking system must be completely
independent of the vehicle's hydraulic
system.
REFUELLING THE VEHICLE
During refuelling procedure, switch off
the engine, engage handbrake, rotate the
ignition key to STOP and do not smoke.
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
Only use 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.
When using or parking the vehicle for a
long time in the mountains or cold areas,
it is advisable to refuel using locally
available Diesel. In this case, it is also
advisable to keep the tank over 50% full.
FUEL TANK CAP
107)
Opening
Open flap 1 fig. 76 pulling it outwards,
hold cap 2 still, insert the ignition key in
the lock and turn it anticlockwise. Then,turn the cap anticlockwise and remove it.
The cap has a loss prevention device
3 which secures it to the flap so that it
cannot be lost. Attach the cap to device
4 during refuelling.
Closing
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.
ENGINES WITH LPGSYSTEM
The gas filler is located next to the petrol
filler cap. It has a "non return", located in
the filler body itself.
To access the filler 2 fig. 77 open the
access flap 1.
