GETTING TO KNOW YOUR CAR

START&STOP
SYSTEM(for versions/markets, where provided)
IN BRIEF
The Start&Stop system automatically
stops the engine each time the car
is stationary and starts it again when
the driver wants to move off.
In this way, the efficiency of the car is
increased, by reducing consumption,
emissions of harmful gases and
noise pollution.
OPERATING MODES
Engine stopping mode
With the car stopped, the engine stops
with gearbox in neutral and clutch
pedal released.
NOTE The engine can only be stopped
automatically after exceeding about
10 km/h, to prevent the engine from

ENGINE STOPPING
FAILURE CONDITIONS
When the system is active, due to
comfort, emission control and safety
reasons, the engine does not stop
in some conditions, among which
10):
❒engine still cold;
❒especially cold outside temperature;
❒battery not sufficiently charged;
❒particulate filter regeneration (DPF) in
progress (diesel engines only);
❒driver's door not shut;
❒driver's seat belt not fastened;
❒reverse gear engaged (for example,
for 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 with
MAX-DEF function activation;
❒during the first period of use, to
initialise the system.ENGINE RESTARTING
CONDITIONS
Due to comfort, emission control and
safety reasons, the engine can restart
automatically without any action by the
driver, under special conditions, such
as:
❒battery not sufficiently charged;
❒reduced braking system vacuum
(e.g. if the brake pedal is pressed
repeatedly);
❒car moving (e.g. when driving on
roads with a gradient);
❒engine stopping by Start&Stop
system for over 3 minutes;
❒for versions equipped with dual zone
automatic climate control system (for
versions/markets, where provided),
if an adequate level of thermal
comfort has not been reached or
MAX-DEF function activation.
With gear engaged, automatic engine
restarting is possible only by fully
depressing the clutch pedal. The driver
is informed by the displaying of a
message on the display and -
for versions/markets, where provided -
by the flashing of the symbol
.Notes
If the clutch is not pressed, about 3
minutes after the engine stops, the
engine can be restarted only using the
ignition key.
In cases when the engine stops and
this is not desired, due for example to
the clutch pedal being released sharply
with a gear engaged, if the Start&Stop
system is activated, the engine can
be restarted by fully depressing the
clutch pedal or by placing the gear lever
in neutral.
SAFETY FUNCTIONS
When the engine is stopped by the
Start&Stop system, if the driver releases
his/her seat belt and opens the driver's
or passenger's door, the engine can
be restarted only using the ignition key.
The driver is informed by a buzzer
and by the flashing of the symbol
on
the display; on some versions, a
message is displayed as well.

"ENERGY SAVING"
FUNCTION
(for versions/markets, where provided)
If, following automatic engine restarting,
the driver does not carry out any
action on the car for over 3 minutes,
the Start&Stop system stops the engine
once and for all, to prevent fuel
consumption. In these cases, the
engine can be restarted only using the
ignition key.
NOTE In any case, it is possible to keep
the engine running by deactivating the
Start&Stop system.IRREGULAR OPERATION
In the event of malfunction, the
Start&Stop system is deactivated.
The driver is informed of the fault by the
flashing
symbol (versions with
multifunction display) or
symbol
(versions with reconfigurable
multifunction display). For versions/
markets where provided, a message is
also displayed.
In this case, contact an Alfa Romeo
Dealership.CAR INACTIVITY
In the event of car inactivity (or if the
battery is replaced), special attention
must be paid to the disconnection
of the battery power supply.
Proceed as follows: detach connector
A fig. 83 (by pressing button B) from
sensor C for monitoring the status
of the battery installed on the negative
battery pole D. This sensor should
never be disconnected from the pole
except if the battery is replaced.
48)
IMPORTANT After turning the ignition
key to STOP, wait at least 1 minute
before disconnecting the electrical
supply to the battery.83

JUMP STARTING
When jump starting, never connect the
negative lead (–) of the auxiliary battery
to the negative pole A fig. 84 of the
car battery, but rather to an
engine/gearbox earth point.
49)
IMPORTANT
10) If you wish to run the air
conditioning system, you may
deactivate the Start&Stop system
to allow continuous operation of
the air conditioning system.
WARNING
48) When replacing the battery,
always contact an Alfa Romeo
Dealership. The replacement
battery should be of the same
type (HEAVY DUTY) and should
have the same characteristics.49) Before opening the bonnet,
make sure that the engine is off
and that the ignition key is in
the STOP position. Follow the
instructions on the dedicated
label on the front crossmember
(fig. 85). We recommend that you
remove the key from the ignition if
other people remain in the car.
The car 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).

iTPMS (indirect Tyre
Pressure
Monitoring System)(for versions/markets, where provided)
DESCRIPTION
The car can be equipped with the
iTPMS (indirect Tyre Pressure
Monitoring System) which monitors the
tyre inflation status thanks to wheel
speed sensors.
The system warns the driver if one or
more tyres are flat by the dedicated
warning light
continuously on and a
warning message on the display.
If one tyre only is flat, the system can
indicate its position: it is anyway
recommended to check the pressure
on all four tyres.
This indication is displayed also when
turning the engine off and on again until
the RESET procedure is carried out.RESET PROCEDURE
The iTPMS system needs an initial
"self-learning" phase (with length
depending on the driving style and road
conditions) which starts when the
RESET procedure is carried out.
The Reset procedure must be carried
out:
❒whenever the tyre pressure is
modified;
❒when even only one tyre is changed;
❒when tyres are rotated/inverted;
❒when the space-saver wheel is fitted.
Before carrying out the RESET, inflate
the tyres to the rated pressure values
specified in the inflation pressure table
(see "Wheels" paragraph in the
"Technical specifications" section).
If the RESET is not carried out, in all
above cases, the warning light
may
give false indications on one or more
tyres.To carry out the RESET, with the car
stopped and the ignition key at
MAR-ON, press the button
fig. 86 on
the dashboard for 2 seconds; after
the RESET, the display shows the
message "RESET SAVED", indicating
that the "self-learning" has started.

OPERATING CONDITIONS
50) 51) 52) 53) 54) 55)
The system is active for speeds above
15 km/h.
In a few situations (such as sporty
driving, winter climate or unmade
roads) the signalling may be delayed.
Under special conditions (e.g. car
loaded asymmetrically on one side,
towing a trailer, damaged or worn tyre,
fitting the space-saver wheel, fitting
snow chains, fitting different tyres on
the axles) the system may give false
indications or be temporarily
deactivated.
If the system is temporarily deactivated,
warning light flashes for about 75
seconds and then is continuously on; at
the same time, the display shows the
message "TYRE PRESSURE
MONITORING NOT AVAILABLE".
This indication is displayed also after
the engine has been switched off and
then on again if the correct operating
conditions are not restored.IMPORTANT
INFORMATION
WARNING
50) If the system signals a pressure
decrease on a specific tyre, it is
recommended to check the
pressure on all four tyres.
51) iTPMS does not relieve the
driver from the obligation to check
the tyre pressure every month; it
is not even to be considered a
replacing system for maintenance
or a safety system.
52) 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.
53) The iTPMS cannot indicate
sudden tyre pressure drops (for
example when a tyre bursts).
In this case, stop the car, braking
with caution and avoiding abrupt
steering.54) The system only warns that the
tyre pressure is low: it is not able
to inflate them.
55) An insufficient tyre inflation
increases fuel consumption,
reduces the tread duration and
may affect the capacity of driving
safely.

EOBD SYSTEM
(European On
Board Diagnosis)(for versions/markets, where provided)
Operation
The EOBD system (European On Board
Diagnosis) carries out a continuous
diagnosis of the components of the car
related to emissions.
It also alerts the driver, by switching on
the
warning light on the instrument
panel, together with a message on
the display, when these components
are no longer in peak condition (see
“Warning lights and messages”
paragraph in the "Knowing the
instrument panel" chapter).
The aim of the EOBD system (European
On Board Diagnosis) is to:
❒monitor the system efficiency;
❒indicate an increase in emissions;
❒indicate the need to replace
damaged components.The car also has a connector, which
can interface with appropriate tools,
that makes it possible to read the error
codes stored in the electronic control
units together with a series of specific
parameters for engine operation and
diagnosis. This check can also be
carried out by the traffic control
authorities.
IMPORTANT After eliminating a fault, to
check the system completely, the Alfa
Romeo Dealership is obliged to run
tests and, if necessary, road tests
which may also require a long journey.
DUAL PINION
ACTIVE STEERINGOperation
This only operates with the key turned
to MAR-ON and the engine started.
The steering allows the force required
at the steering wheel to be adjusted
to suit driving conditions. The different
power assistance modes can be
selected via the d, n, a positions of the
“Alfa DNA System” lever (see paragraph
entitled “Alfa DNA System”).
56)
IMPORTANT After the battery is
disconnected, the steering must be
initialised. The warning light switches on
to indicate this. To carry out this
procedure, simply turn the steering
wheel all the way from one end to the
other or drive in a straight line for about
a hundred metres.
