2012 Alfa Romeo MiTo stop start

114GETTING TO KNOW YOUR CAR
NoteThe engine automatic stop is allowed only after having run
at about 10 km/h, to prevent repeated engine stops when driving
at a very slow speed. The engine stopping is signalled by display-
ing the
Usymbol in fig. 71.
Engine re-starting mode
To restart the engine, press the clutch pedal.
SYSTEM MANUAL ACTIVATION/DEACTIVATION
To activate/deactivate the system, press the button fig. 72 on
the trim next to the steering wheel. When the system is deacti-
vated, the
Uwarning light in the instrument panel switches on.
For versions/markets, where fitted, a message plus a symbol on
the display may appear in the event of activation/deactivation of
the system.
START&STOP SYSTEM
(for versions/markets, where provided)
The Start&Stop system stops the engine automatically when the
vehicle stops and starts it again when the driver wants to resume
driving. In this way, the vehicle efficiency is increased, by reduc-
ing consumption, dangerous gas emissions and sound pollution.
The system is active every time the engine is started.
OPERATING MODE
Engine stopping mode
With stopped vehicle, the engine stops with gearbox in neutral and
released clutch pedal.

ENGINE FAILED STOPPING CONDITIONS
When the system is operating, due to comfort, emission control
and safety reasons, the engine could not stop in some conditions,
among which:
❍still cold engine;
❍especially cold outside temperature;
❍insufficiently charged battery;
❍operating heated rear window;
❍windscreen-wiper operating at max. speed;
❍particulate filter (DPF) regeneration in progress (only for Diesel
engines);
❍open driver's door;
❍unfastened driver's seat belt;
❍engaged reverse (for example during parking manoeuvres);
❍for versions equipped with dual zone automatic climate control
(for versions/markets, where provided), if an adequate level
of thermal comfort has not been reached or MAX-DEF func-
tion activation;
❍during the first utilization period, for the system initialisation.
In these cases, the display shows a message and - for those ver-
sions/markets where it has been fitted - the
Usymbol on the
display flashes.
ENGINE RESTARTING CONDITIONS
Due to comfort, emission control and safety reasons, the engine
can be restarted automatically without any intervention by the
driver, under special conditions, such as:
❍insufficiently charged battery;
❍windscreen-wiper operating at max. speed;
❍low vacuum in the braking system (for example after repeat-
ed actions on the brake pedal);
❍moving vehicle (for example while driving downhills);
❍engine stopping by Start&Stop system for over 3 minutes;
❍for versions equipped with dual zone automatic climate control
(for versions/markets where provided), to enable suitable ther-
mal comfort or MAX-DEF function activation.
With engaged gear, the engine automatic restarting is possible
only by fully pressing the clutch pedal. The driver is informed by
the displaying of a message and - for versions/markets where it
has been fitted - by the flashing of the
Usymbol on the display.
Notes
If the clutch is not pressed, after 3 minutes from the engine stop-
ping, the engine can be restarted only by the ignition key.
In case of undesired engine stopping conditions, for example as a
result of sudden clutch pedal release with engaged gear, if the
Start&Stop system is active, the engine can be restarted by fully
pressing the clutch pedal or placing the gearbox in neutral.
If temperature comfort is to be preferred, deac-
tivate the Start&Stop system to make the climate
control system work continuously

SAFETY CONDITIONS
When the engine is stopped by the Start&Stop system, if the dri-
ver releases his/her seat belt and opens the driver's or passenger's
door, the engine can be restarted only by the ignition key.
This condition is signalled by a buzzer and by a displayed message
and - for versions/markets where it has been fitted - by the flash-
ing of the
Usymbol on the display.
"ENERGY SAVING" FUNCTION
(for versions/markets, where provided)
If, as a result of the engine automatic restarting, the driver does not
make any action on the vehicle for over 3 minutes, the Start&Stop
system stops the engine once and for all, to prevent fuel consump-
tion. In these cases, the engine can be restarted only by the igni-
tion key.
Note In any case, the engine can be still kept running by deactivat-
ing the Start&Stop system.
OPERATING IRREGULARITIES
In case of malfunctioning conditions, the Start&Stop system is
deactivated. The driver is informed about the failure through the
switching-on of the warning light
èon the instrument panel and
- for versions/markets where it has been fitted - through the dis-
playing of a message + symbol. In this case, contact Alfa Romeo
Authorised Service.

CAR INACTIVITY
(with Start&Stop system with dummy pole)
(for versions/markets where provided)
In case of vehicle inactivity conditions, pay special attention to
the disconnection of the battery power supply. The procedure must
be made by disconnecting the quick release negative terminal
A-fig. 73 from the dummy negative pole B, as the battery nega-
tive pole C has a sensor D for battery condition monitoring that
must never be disconnected (unless the battery is replaced).
CAR INACTIVITY
(with Start&Stop system without dummy pole)
(for versions/markets where provided)
In case of car inactivity, special attention must be paid due to the
disconnection of the battery power supply. Proceed as follows:
detach the connector A-fig. 74 (by pressing button B) from sen-
sor C for monitoring the battery status installed on the battery neg-
ative pole D. This sensor should never be disconnected from the
pole except if the battery is replaced.
fig. 73A0J0249m
In case of battery replacement, always contact
Alfa Romeo Authorised Service. Replace the bat-
tery using a new one of the same type (HEAVY
DUTY) and having the same specifications.

EMERGENCY STARTING
(with Start&Stop system with dummy pole)
(for versions/markets where provided)
In case of vehicle jump starting, never connect the negative cable
(–) of the auxiliary battery to the negative pole B - fig. 75 of the
vehicle battery, rather to the dummy pole A or to an en-
gine/gearbox earth point.

EMERGENCY STARTING
(with Start&Stop system without dummy pole)
(for versions/markets where provided)
When jump starting, never connect the negative lead (–) of the
auxiliary battery to the negative pole A - fig. 76 of the car bat-
tery, but rather to an engine/gearbox earth point.

134SAFETY
The warning lights can be red and green and they operate as fol-
lows (fig. 4):
❍1=front left seat (driver's condition 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's condition for left-hand drive
versions)
Front seats (warning light no. 1 = driver and
no. 5 = passenger)
Driver
If the driver is the only occupant and his seat belt is unfastened,
when 20 km/h is exceeded or when travelling at a speed from 10
to 20 km/h for longer than 5 seconds, an acoustic reminder se-
quence will be started for front seats, consisting of a tone for 6 sec-
onds followed by a 90 second beep. The warning light will blink.
The warning lights will stay on fixed at the end of the cycle until
the engine is stopped. The acoustic reminder will be interrupted im-
mediately 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 situation arises for the front passenger, except that the
warning lights becomes green and the signal also stops when the
passenger leaves the car. In the event that both front seat belts are
unfastened with the vehicle in motion, a few seconds apart, the
acoustic signal refers to the most recent event, while both warning
lights display a visual signal independently of one another.
Rear seats (warning light no. 2, no. 3 and no. 4)
For rear seats, the reminder cycle is run only when any seat belt
is unfastened (red flashing warning light). In this condition, the
warning light referred to the seat belt which has been unfastened
will become red and blink for approximately 30 seconds. There is
also an acoustic signal.
The visual indication (red flashing) will start and stop independently
for each warning light if several seat belts are unfastened. The warn-
ing light will become green when the relevant seat belt is fas-
tened again.
After about 30 seconds from the last reminder, the warning lights
for rear seats will switch off, independently of the belt conditions
(red or green).
IMPORTANT NOTES
The warning lights are all off if all seat belts (front and rear) are
already fastened when the ignition key is turned on MAR.
All warning lights will light up when at least one belt goes from fas-
tened to unfastened or vice versa.

154STARTING UP AND DRIVING
STARTING THE ENGINE
STARTING PROCEDURE FOR PETROL VERSIONS
Proceed as follows:
❍engage the handbrake and place the gearbox in neutral;
❍press the clutch pedal down to the floor without touching the
accelerator;
❍turn the ignition key to AVV and let it go the moment the en-
gine starts.
IMPORTANT NOTES
❍If the engine does not start on the first attempt, turn the igni-
tion key to STOP before repeating the operation.
❍If, when the ignition key is on MAR, the Ywarning light (or
symbol in the display) remains lit together with the
Uwarning
light, turn the key to STOP and then back to MAR; if the warn-
ing light remains on, try using the other keys provided with the
car. If you are still unable to start the engine carry out the emer-
gency starting procedure (see “Emergency Start-up” in chap-
ter 4) and contact an Alfa Romeo Authorised Service Provider.
❍Never leave the ignition key on MAR when the engine is off.
PROCEDURE FOR DIESEL VERSIONS
Proceed as follows:
❍engage the handbrake and place the gearbox in neutral;
❍turn the ignition key to MAR: the mandYwarning lights
(or symbol in the display) will come on;
❍wait for the warning light (or symbol in the display) to go
out;
❍press the clutch pedal down to the floor without touching the
accelerator;
❍turn the ignition key to AVV as soon as the mwarning light
goes out. Waiting too long will waste the work done by the
glow plugs. Release the key as soon as the engine starts.
If warning light mblinks for 60 seconds after
starting or during prolonged cranking, this indi-
cates a fault in the glow plug pre-heating system.
Use the car normally if the engine starts and contact an
Alfa Romeo Authorised Services provider as soon as pos-
sible.
Is is dangerous to let the engine run in enclosed
spaces. The engine depletes oxygen and discharges
carbon dioxide, carbon monoxide and other toxic
gases.

STARTING UP AND DRIVING155
3
In the initial period of use, it is advisable to avoid
placing the car under excessive stress (for instance
excessive acceleration, extended travel at maxi-
mum speed, sharp braking etc.).
Remember that the servo brake and electric pow-
er steering are not operational until the engine has
been started, therefore more effort than usual is
required on the brake pedal and steering wheel.
Avoid jump starting the engine by pushing, towing
or driving downhill. These manoeuvres may dam-
age the catalytic converter.
When the engine is off, do not leave the key in
the ignition switch turned to MAR to avoid drain-
ing the battery.
HOW TO WARM UP THE ENGINE AFTER IT HAS
JUST STARTED (petrol and diesel engines)
Proceed as follows:
❍drive off slowly, letting the engine turn at medium speed. Do
not accelerate abruptly;
❍do not demand maximum performance for the first few kilo-
metres. Wait until the engine coolant gauge starts moving.
EMERGENCY START
If the Ywarning light in the instrument panel remains on con-
stantly, contact an Alfa Romeo Authorised Service Provider.
STOPPING THE ENGINE
Turn the ignition key to STOP while the engine is idling.
IMPORTANT After a taxing drive, before turning the engine off you
should allow it to idle to allow the temperature in the engine com-
partment to fall.
A quick burst on the accelerator before turning off
the engine serves absolutely no practical purpose,
it wastes fuel and is damaging, especially to tur-
bocharged engines.
