light Alfa Romeo MiTo 2017 Service Manual

WARNING
47)The presence of the TPMS does not
permit the driver to neglect regular checks
of the tyre pressure, including for the spare
wheel.
48)Tyre pressure must be checked with
tyres cold. Should it become necessary for
whatever reason to check pressure with
warm tyres, do not reduce pressure even
though it is higher than the prescribed value,
but repeat the check when tyres are cold.
49)Should one or more wheels be fitted
without sensors, the system will no longer be
available and, in addition to the TPMS
warning light flashing for less than one
minute before becoming constant, a warning
message will be shown on the display, until
4 wheels with sensors are fitted again.
50)The TPMS cannot warn of sudden
decreases in tyre pressure (for example
when a tyre bursts). In this case, stop the car,
braking with caution and avoiding abrupt
steering.
51)Replacing standard tyres with winter
tyres (and vice versa) requires TPMS
adjustment that must only be performed by
a dedicated Alfa Romeo Dealership.
52)Changes in outside temperature may
cause tyre pressures to vary. The TPMS
system may temporarily indicate
insufficient pressure. In this case, check the
tyre pressure when cold and, if necessary,
restore the inflation values.53)When a tyre is removed, it is advisable
to replace the rubber valve seal as well:
contact a dedicated Alfa Romeo Dealership.
Tyre and/or rim fitting/removal operations
require specific precautions; to avoid
damaging or fitting the sensors incorrectly,
tyre and/or rim fitting/removal operations
should only be carried out by specialised
staff. Contact a dedicated Alfa Romeo
Dealership.
54)Intense radio-frequency interference
may prevent the correct operation of the
TPMS. This condition will be indicated by a
message on the display. The message will
disappear automatically as soon as the
radio-frequency interference ceases to
affect the system.
55)The tyre repair kit (Fix&Go) provided
with the vehicle (for versions/markets,
where provided) is compatible with the
TPMS sensors; using sealants not equivalent
with that in the original kit may adversely
affect its operation. If sealants not
equivalent with the original one are used, it is
recommended to have the TPMS sensors
checked by a qualified repair centre.
SEAT BELTS
USING THE SEAT BELTS
56) 57) 58)
All vehicle seats are equipped with seat
belts with three anchor points and a
retractor.
The retractor mechanism operates
locking the belt in the event of sharp
braking or strong deceleration due to an
impact. This allows the belt strap to slide
freely and to adapt to the body of the
occupant. In the event of an accident, the
belt will lock reducing the risk of impact
inside the passenger compartment and
of being projected outside the vehicle.
The driver is responsible for respecting,
and ensuring that all the other occupants
of the vehicle also respect, the local laws
in force in relation to the use of the seat
belts.
Always fasten the seat belts before
setting off.
Using the seat belts
The belt should be worn keeping the
torso straight and rested against the
backrest.
To fasten the safety belts, hold the
tongue 1 fig. 43 and insert it into the
buckle 2, until it clicks into place. If the
seat belt jams during removal, let it
rewind for a short stretch, then pull it out
70
SAFETY
again without jerking.

SBR SYSTEM (Seat Belt
Reminder)
It consists of an acoustic warning which,
switching on the
warning lights in the
trim located on the fig. 46 internal rear
view mirror, warns passengers in the
front and rear seats that their seat belts
are not fastened.
For long-term deactivation of the SBR
system, contact a Alfa Romeo
Dealership.
The SBR system can be reactivated at
any time through the Setup Menu only
(see “Menu Items” in “Knowing your
vehicle” section).
The warning lights may be red or green
and operate as follows:
1 = front left seat (driver status for
left-hand drive versions)
2 = rear left seat (passenger);
3 = rear centre seat (passenger)
4 = rear right seat (passenger);
5 = front right seat (passenger status
for left-hand drive versions).
NOTE On versions equipped with sport
front seats, the indication of passenger
side seat belt fastened (warning light
1 for right-hand drive versions or warning
light 5 for left-hand drive versions) will
never be displayed.
FRONT SEATS (warning light 1 = driver
and 5 = passenger)
Driver
If the driver is the only occupant and the
seat belt is not fastened, when 20 km/h
is exceeded or when travelling at a speed
from 10 to 20 km/h for longer than
5 seconds, a buzzer sequence will be
started (front seats) consisting of a tone
for 6 seconds followed by a 90 second
beep.The warning light will blink.
The warning lights will stay on constantly
at the end of the cycle until the engine is
stopped. The acoustic signal will be
interrupted immediately when the
driver’s seat belt is fastened and the
warning light will turn green.
The reminder cycle (acoustic and visual)
will be repeated as described above and
the red warning light will flash if the seat
belt is unfastened again while travelling.Passenger
A similar solution applies for the front
passenger, with the difference that the
warning light turns green and the signal is
interrupted also when the passenger
leaves the car.
It both front seat belts are unfastened
while the vehicle is travelling a few
seconds apart, the acoustic indication
will refer to the most recent event and
the two warning lights will proceed with
the visual indication independently.
REAR SEATS (warning light 2, 3 and 4)
The reminder cycle is run only when any
seat belt is unfastened (red blinking).
In this condition, the warning light for the
seat belt which has been unfastened will
start flashing red for approximately
30 seconds. An acoustic signal is also
emitted.
The visual indication (blinking red) will
start and end independently for each
warning light if several seat belts are
unfastened. The warning light will
become green when the relevant seat
belt is fastened again.
After about 30 seconds from the last
indication, the warning lights for rear
seats will switch off, irrespective of the
belt conditions (red or green).
46A0J0108C
72
SAFETY

All warning lights will remain off if all
the seat belts (front and rear) are already
fastened when the key it turned to MAR.
All the warning lights will come on
when at least one belt changes from
fastened to unfastened status or vice
versa.
PRE-TENSIONERS
59) 60)
The vehicle is equipped with front seat
belt pretensioners, which draw back the
seat belts by several centimetres in the
event of a strong frontal impact. This
guarantees the perfect adherence of the
seat belts to the occupant's bodies
before the retention action begins.
It is evident that the pretensioners have
operated when the belt withdraws
toward the retractor.
This car is also equipped with a second
pretensioner (fitted in the kick plate
area). Its activation is signalled by the
shortening of the metal cable.
A slight discharge of smoke may be
produced during the activation of the
pretensioner which is not harmful and
does not involve any fire hazard.
IMPORTANT To obtain the highest
degree of protection from the action of
the pretensioner, wear the seat belt tight
to the torso and pelvis.
The pretensioner does not require any
maintenance or lubrication: any changes
to its original conditions will invalidate its
efficiency. If, due to unusual natural
events (floods, sea storms, etc.), the
device has been affected by water and/or
mud, contact an Alfa Romeo Dealership
to have it replaced.
LOAD LIMITERS
To increase passenger safety, the front
seat belt reels contain a load limiter
which allows the force acting on the chest
and shoulders to be modulated during the
belt restraining action in the event of a
frontal impact.
GENERAL INSTRUCTIONS FOR USING
THE SEAT BELTS
61) 62)
Seat belts must also be worn by pregnant
women: the risk of injury in the event of
an accident is reduced for them and the
unborn child if they are wearing a seat
belt.
Pregnant women must position the lower
part of the belt very low down so that it
passes over the pelvis and under the
abdomen fig. 47.
The belt must not be twisted. The upper
part must pass over the shoulder and

IMPORTANT NOTES

Main recommendations to carry
children safely
Install the child restraint systems on
the rear seat, which is the most protected
position in the event of an impact.
Keep children in rearward facing child
restraint systems for as long as possible,
at least until 3–4 years old.
Should a rearward facing child
restraint system be installed on the rear
seats, it is advisable to position it as far
forward as the position of the front seat
allows.
If the passenger side front airbag is
deactivated always check the permanent
switching on of the warning light
in
the trim above the interior rear view
mirror to make sure that it has actually
been deactivated.
Carefully follow the instructions
supplied with the child restraint system
itself. Keep the instructions in the vehicle
along with the other documents and this
handbook. Do not use second-hand child
restraint systems without instructions.
Only one child is to be strapped into
each restraint system; never carry two
children simultaneously.
Always check that the seat belts do
not rest on the child’s neck.
Always check that the seat belt is well
fastened by pulling on it.
While travelling, do not let the child sit
incorrectly or unfasten the belts.
Never allow a child to put the belt's
diagonal section under an arm or behind
their back.
Never carry children on your lap, even
newborns. No one can hold a child in the
case of an accident.
In the event of an accident, replace the
child restraint system with a new one. In
addition, and depending on the type of
child restraint system installed, replace
the seat belt with which the child
restraint system was connected.
WARNING
73)The diagram is indicative and for fitting
purposes only. Fit the child restraint system
according to the instructions, which must be
included.
74)If a Universal ISOFIX child seat system
is not fixed to all three anchorages, it will not
be able to protect the child correctly. In a
crash, the child could be seriously or fatally
injured.
75)Fit the child restraint system when the
car is stationary. The child restraint system
is correctly secured to the brackets when
you hear the click. Follow the instructions for
assembly, disassembly and positioning that
the Manufacturer must supply with the child
restraint system.
76)Do not use the same lower anchorage to
install more than one child restraint system.
FRONT AIRBAGS
77) 78) 79) 80) 81)
“SMART BAG”SYSTEM (MULTISTAGE
FRONT AIRBAGS)
The car features multistage front airbags
(“Smart bag”) for driver and passenger.
The front driver/passenger airbags are
designed to protect occupants in the
event of frontal impacts of medium-high
severity, by placing the bag between the
occupant and the steering wheel or
dashboard.
Therefore non-activation in other types
of collisions (side collisions, rear shunts,
roll-overs, etc.) is not a system
malfunction.
Airbags are not a replacement of but
complementary to the seat belts, which
you are recommended to always wear. In
the event of impact, those not wearing a
seat belt are projected forwards and may
come into contact with the bag which is
still inflating. The protection offered by
the bag is compromised in these
circumstances.
Front airbags may not activate in the
following situations:
frontal impacts against highly
deformable objects not involving the
front surface of the car (e.g. wing collision
against guard rail, etc.);
81

jamming of the car underneath other
vehicles or protective barriers (e.g.
underneath a truck or a guard rail) as, in
this case, the bags would offer no
additional protection with respect to the
seat belt and their deployment would be
inappropriate. Failure to activate in the
conditions described above is due to the
fact that they may not provide any
additional protection compared with seat
belts, so their activation would be
inappropriate. In these cases,
non-deployment does not indicate a
system malfunction.
FRONT AIRBAG DRIVER'S SIDE
This consists of an instantly inflating
cushion contained in a special
compartment in the centre of the
steering wheel fig. 57.
PASSENGER SIDE FRONT AIRBAG
This consists of an instantly inflating bag
contained in a special recess in the
dashboard fig. 58 which has a larger
volume than that of the driver.
FRONT PASSENGER SIDE AIRBAG AND
CHILD RESTRAINTSYSTEMS
Rearward facing child restraint systems
mustNEVERbe fitted on the front seat
with an active passenger airbag since in
the event of an impact the airbag
activation may cause fatal injuries to the
transported child.ALWAYScomply with
the instructions on the label on the
passenger side sun visor fig. 59.Deactivating passenger side airbags:
front airbag and side bag for pelvis,
chest protection (Side bag)
If a child must be carried on the front seat
in a rear facing child restraint system,
deactivate the passenger side front
airbag and side bag for pelvis, chest
protection (Side bag). To deactivate the
airbags use the Setup Menu (see the
instructions in the “Display” paragraph,
“Knowing the instrument panel” chapter).
With airbags deactivated, a warning light
lights up on the instrument panel in
the trim located above the internal
rearview mirror fig. 60.

SAFETY

With front passenger airbag on, when the
ignition key is turned to MAR, the warning
light switches on constantly for several
seconds and then it should switch off.
If the warning light
flashes, this
indicates a fault in the warning light
.
Before proceeding, contact an Alfa
Romeo Dealership to have the system
checked immediately.
Rotating the starting device to MAR, the
warning light
switches on for a few
seconds. If not, contact an Alfa Romeo
Dealership. During the first seconds, the
activation of the warning light
does
not actually show the passenger
protection status, but only tests its
correct operation. After a test of a few
seconds, the warning light will indicate
the status of the passenger airbag
protection.Passenger protection active: warning
light
off.
Passenger protection deactivated: the
warning light
switches on with a
steady light.
The warning light
may light up with
various intensity levels depending on the
vehicle conditions. The intensity may vary
during the same key cycle.
DRIVER SIDE KNEE BAG
This is located in a dedicated
compartment under the steering wheel
fig. 61. It provides additional protection
in the event of a frontal impact.

WARNING
77)Do not apply stickers or other objects on the steering wheel, on the dashboard in the passenger side airbag area, on side upholstery on the roof
or on the seats. Never put objects (e.g. mobile phones) on the passenger's side dashboard since they could interfere with correct inflation of the
airbag and also cause serious injury to the passengers.
78)Always drive keeping your hands on the steering wheel rim so the airbag can inflate freely if necessary. Do not drive with your body bent
forward. Keep the back of your seat upright and lean back into it.
79)When there is an active passenger airbag, DO NOT install rearward facing child restraint systems on the front seat. Deployment of the airbag
in an accident could cause fatal injuries to the child regardless of the severity of the impact. 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.
80)To deactivate the airbags, see the “Knowing your car” section, “Menu items” paragraph.
81)A failure of the
warning light is indicated by thewarning light switching on. In addition, the airbag system automatically disables the
passenger side airbag (where provided). Before proceeding, contact an Alfa Romeo Dealership to have the system checked immediately.
85

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.
87

STARTING THE ENGINE
93) 94) 95)
17) 18) 19) 20)
Before starting the engine, adjust the
seat, the interior rear view mirrors, the
door mirrors and fasten the seat belt
correctly.
Never press the accelerator pedal for
starting the engine.
If necessary, messages indicating the
starting procedure can be shown on the
display.
PROCEDURE FOR PETROL VERSIONS
Except Turbo TwinAir versions
Proceed as follows:
engage the handbrake and place the
gearbox lever in neutral;
fully depress the clutch pedal, without
touching the accelerator;
turn the ignition key to AVV and
release it as soon as the engine starts.
Turbo TwinAir versions
Proceed as follows:
engage the handbrake and place the
gear lever in neutral or fully press the
clutch pedal if a gear other than neutral is
engaged;
turn the ignition key to AVV and
release it as soon as the engine starts.Versions with LPG system
To properly perform the starting
procedure, refer to as previously
described.
The engine always starts up on petrol
independently of the mode previously
selected. There must therefore always be
some petrol in the tank to protect the
petrol pump and to guarantee temporary
switching from LPG to petrol operation, if
high performance is required.
IMPORTANT NOTES
Except Turbo TwinAir versions:Ifthe
engine does not start at the first attempt,
return the ignition key to STOP before
repeating the procedure.
For Turbo TwinAir versions only:Ifthe
vehicle does not start at the first
attempt, return the ignition key to STOP
and repeat the starting procedure placing
the gear lever in neutral and fully
pressing the clutch pedal.
If, with the ignition key turned to MAR,
the
symbol is shown on the display
together with the warning light
, turn
the key to STOP and then back to MAR. If
the symbol on the display is still shown,
try with the other keys provided with the
car. Contact an Alfa Romeo Dealership if
the engine still does not start.
Never leave the ignition key in
MAR-ON position when the engine is
stopped.
PROCEDURE FOR DIESEL VERSIONS
Proceed as follows:
engage the handbrake and place the
gear lever in neutral;
turn the ignition key to MAR position:
the
warning light will light up on
instrument panel;
wait for the warning light to switch off;
fully depress the clutch pedal, without
touching the accelerator;
turn the ignition key to AVV; the
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.
WARNING
93)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.
94)The brake servo is not active until the
engine is started, so you would need to apply
much more force than usual to the brake
pedal.
95)Do not start the engine by pushing,
towing or driving downhill. These
manoeuvres may damage the catalytic
converter.
90
STARTING AND DRIVING

IMPORTANT
17)We recommend that during the initial
period, or during the first 1600 km
(1000 miles), you do not drive to full car
performance (e.g. excessive acceleration,
long journeys at top speed, sharp braking,
etc.).
18)When the engine is switched off never
leave the ignition device in the MAR position
to prevent useless current absorption from
draining the battery.
19)A quick burst on the accelerator before
turning off the engine serves absolutely no
practical purpose; it wastes fuel and is
damaging for the engine.
20)Warning light
will flash after starting
or during prolonged cranking to indicate a
fault with the glow plug heating system. If
the engine starts, the vehicle can be regularly
used, but an Alfa Romeo Dealership must be
contacted as soon as possible.
PARKING THE VEHICLE
96) 97)
Always remove the ignition key when
leaving the car.
When parking and leaving the car,
proceed as follows:
engage a gear (1stgear if facing uphill
or reverse if facing downhill) and leave
the wheels turned;
stop the engine and engage the
handbrake.
Block the wheels with a wedge or a stone
if the car is parked on a steep slope.
On versions equipped with Alfa TCT
transmission, before releasing the brake
pedal, wait for letter P to be displayed.
IMPORTANTNEVERleave the car with
the gearbox in neutral (or, on versions
equipped with Alfa TCT transmission,
before placing the gear lever at P).
HANDBRAKE
To engage the handbrake, pull lever 1
fig. 65 upwards until the car is secured.
When the handbrake is engaged and the
ignition key is on MAR-ON, the
instrument panel warning light
will
switch on.
To release it, raise lever 1 slightly, hold
down button 2 and lower the lever: the
warning light
on the instrument
panel switches off.
IMPORTANT Carry out these
manoeuvres with the brake pedal
pressed.
IMPORTANT For cars equipped with a
front armrest, lift it up to ensure that it
does not interfere with the action of the
handbrake.
WARNING
96)Never leave children unattended in the
car. Always remove the key from the ignition
when leaving the car and take it with you.
97)The car should be braked after a few
clicks of the parking brake: if this is not so,
contact an Alfa Romeo Dealership to have it
adjusted. Always park the car safely as
indicated by the Highway Code and as
described above.
