2021 Alfa Romeo MiTo check engine light

WARNING
82)Do not affix rigid objects to the garment
hooks or support handles.
83)Do not rest your head, arms or elbows on
the door, windows or the area in which the
Window bag is located to avoid possible
injury during airbag inflation.
84)Never lean your head, arms or elbows
out of the window.
85)If the
warning light does not switch
on when the key is turned to MAR, 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 an Alfa Romeo Dealership to have
the system checked immediately.
86)Do not travel carrying objects on your
lap, in front of your chest or between your
lips (pipe, pencils, etc.): they could cause
severe injury if the airbag is deployed.
87)If the car has been subject to theft,
attempted theft, vandalism, or flooding,
have the airbag system inspected at an Alfa
Romeo Dealership.88)The airbags may also be deployed when
the car is not moving, if the key is in the
ignition and turned to MAR-ON or when the
engine is off, if the car is hit by another
moving vehicle. Therefore, even if the vehicle
is stationary, when an active front
passenger airbag is fitted, DO NOT install
rearward 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 side airbag when a
rearward 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
prevent 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.
89)When the ignition key is turned to MAR,
the
warning light switches for few
seconds, then if the passenger airbag is
active it should switch off.
90)The front airbag is designed to be
deployed for impacts of a greater intensity
than for the pretensioners. For impacts
whose intensity falls between the two levels,
normally, only the pretensioners will be
activated.91)The airbag does not replace seat belts
but increases their efficiency. Because front
airbags are not deployed for low-speed
crashes, side collisions, rear-end shunts or
rollovers, occupants are protected, in
addition to any side bags, only by their seat
belts, which must therefore always be
fastened.
92)On cars with side bags, do not cover the
front seat backrests with extra covers.

WARNING
117)The space-saver wheel is specific for
your car. Do not use it on cars of different
models. Do not use space-saver wheels of
different models on your car. The
space-saver wheel must only be used in the
event of an emergency. Never use it for more
than strictly necessary and never exceed
80 km/h. On the space-saver wheel there is
an orange label, summarising the main
warnings regarding space-saver wheel
usage restrictions. Never remove or cover
the label. Never apply any hub cap to the
space-saver wheel.118)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. On hills or uneven roads, use
chocks or appropriate objects to block the
wheels of the vehicle.
119)The vehicle's driving characteristics
will be modified with the space-saver wheel
fitted. Avoid violent acceleration and
braking, abrupt steering and fast cornering.
The overall duration of the space-saver
wheel is about 3000 km, after which the
relevant tyre must be replaced with another
one of the same type. Never install a
traditional tyre on a rim designed to be used
as a space-saver wheel. Have the wheel
repaired and refitted as soon as possible.
Using two or more space-saver wheels at the
same time is forbidden. Do not apply grease
to the bolt threads before fitting: they could
come unscrewed.
120)The jack may be used to replace
wheels only on the car that it comes with or
other cars of the same model. Never use the
jack for other purposes, such as lifting other
vehicle models. Never use it for repair
operations under the vehicle. Incorrect
positioning of the jack may cause the vehicle
to fall. Do not use the jack for loads higher
than the one shown on its label. Never install
snow chains on the space-saver 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
space-saver wheel on the rear axle. In this
way, with two normal front drive wheels, it is
possible to use snow chains.121)Incorrectly fitting the wheel cap may
cause it to fall off when the car is in motion.
Never tamper with the inflation 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").
122)The jack is a tool developed and
designed only for changing a wheel, if a tyre
gets punctured or damaged, on the vehicle
with which it is supplied or on other vehicles
of the same model. Any other use, e.g. to jack
up other vehicle models or different things,
is strictly prohibited. Never use for
maintenance or repair activities under the
car or to exchange the summer/winter
wheels and vice versa. Never go under the
raised vehicle. Should it be necessary to
work under the vehicle, contact an Alfa
Romeo Dealership. Incorrect positioning of
the jack may cause the raised vehicle to fall:
use only in the positions indicated. Do not
use the jack for loads higher than the one
shown on its label. Never start the engine
with vehicle raised. If the vehicle is raised
more than necessary, everything can
become more unstable, with the risk of the
vehicle dropping violently. Thus, lift the
vehicle only as needed in order to access the
spare wheel.

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;

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.
