PARKING ON FLAMMABLE MATERIAL
The catalytic converter develops high temperatures during operation. Do not park the car on grass, dry leaves, pine needles or other flammable material: fire
hazard.
RESPECTING THE ENVIRONMENT
The car is fitted with a system that carries out a continuous diagnosis of the emission-related components in order to help protect the environment.
ELECTRICAL ACCESSORIES
If, after buying the car, you decide to add electrical accessories (with the risk of gradually draining the battery), contact an Alfa Romeo Dealership. They will
calculate the overall electrical requirement and check that the car’s electrical system can support the required load.
CODE card(for versions/markets, where provided)
Keep it in a safe place, not in the car. We recommend that you always carry the electronic code provided on the CODE card with you, in case you need to
perform an emergency start.
SCHEDULED SERVICING
Correct maintenance of the car is essential for ensuring that it maintains its performance and its safety features, its environmental friendliness and low running
costs for a long time to come.
THE OWNER MANUAL CONTAINS…
… important information, advice and warnings for correct use, driving safety and maintenance of your car over time. Particular attention should be paid to
information marked with the following symbols: (personal safety) (environmental protection) (car integrity).

ALARM(for versions/markets, where provided)
ALARM ACTIVATION
The alarm activates in the following
cases:
❒wrongful opening of a door/bonnet/
luggage compartment (perimeter
protection);
❒wrongful operation of the ignition
switch (ignition key turned to
MAR-ON);
❒cutting of the battery cables;
❒movement inside the passenger
compartment (volumetric protection);
❒anomalous lifting/tilting of the car (for
versions/markets, where provided).
Operation of the alarm is indicated by
an acoustic and visual signal (flashing of
the direction indicators for several
seconds). The alarm activation modes
may vary according to the market.
There is a maximum number of
acoustic/visual cycles. When this is
reached the system returns to normal
operation.IMPORTANT The engine locking
function is guaranteed by the Alfa
Romeo CODE, which is automatically
activated when the ignition key is
extracted from the ignition switch.
IMPORTANT The alarm is adapted to
meet requirements in various countries.
SWITCHING ON THE
ALARM
With the doors, bonnet and tailgate
closed and the ignition key either
turned to STOP or removed, point the
key with remote control towards the car
and press and release the
button.
Except for specific markets, the system
emits a visual and acoustic signal and
enables door locking.
A self-diagnosis stage precedes the
switching on of the alarm: in the event
of faults, the system will generate a
further acoustic and/or visual signal
through the LED on the dashboard.
If after the alarm is switched on, a
second acoustic signal is emitted
and/or a visual signal via the LED on
the dashboard, wait about 4 seconds
and switch off the alarm by pressing the
button, check that the doors,
bonnet and luggage compartment are
closed correctly and then reactivate the
system by pressing the
button.If the alarm emits an acoustic signal
even when the doors, bonnet and
luggage compartment are correctly
closed, a fault has occurred in system
operation: in this case, contact an
Alfa Romeo Dealership.
ALARM SELF-ACTIVATION
(for versions/markets, where provided)
If the alarm has not been activated
using the remote control, once about
30 seconds have elapsed from when
the ignition key was turned to STOP
and a door or the tailgate was last
opened and then closed, the alarm
activates automatically.
This is indicated by the LED on the
button A fig. 10 lighting up intermittently
and the indications of activation
described previously.
To deactivate the alarm, press the
button on the remote control.
The alarm also activates when the
doors are closed by turning the metal

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.

Warning lights on
panelWhat it means What to do
redALTERNATOR FAILURE
The warning light switches on when the ignition
key is turned to MAR-ON, but it should switch off
as soon as the engine has started (with the
engine idling a brief delay before switching off is
acceptable).If the warning light (or symbol on the display)
stays on constantly or flashing, contact an Alfa
Romeo Dealership as soon as possible.
WARNING
63) If the
warning light does not switch on when the key is turned to MAR-ON or if it stays on when driving (together
with the message on the display), there may be a fault in the restraint systems; in this case, the airbags or
pretensioners may not deploy in the event of an accident or, in a lower number of cases, they could deploy
erroneously. Before proceeding, contact an Alfa Romeo Dealership to have the system checked immediately.
64) Failure of the
warning light is signalled by the flashing for longer than the usual 4 seconds of the
warning light
(located in the trim above the internal rear view mirror). In addition, the airbag system automatically disables the
passenger side airbag. In this case, the
warning light may not indicate a fault in the restraint systems. Before
proceeding, contact an Alfa Romeo Dealership to have the system checked immediately.

redENGINE COOLANT TEMPERATURE
TOO HIGH
When the key is turned to MAR-ON, the warning
light switches on but should switch off after a few
seconds. The warning light turns on when the
engine is overheated.
The display shows the dedicated message.When driving normally: stop the car, switch off the
engine and check that the water level in the
reservoir is not below the MIN mark. If it is, wait
for the engine to cool down, then slowly and
carefully open the cap, top up with coolant and
check that the level is between the MIN and MAX
marks on the reservoir. Also check visually for any
fluid leaks. Should the warning light turn on again
at the next start-up, contact an Alfa Romeo
Dealership.
If the car is used under demanding conditions
(e.g. in high-performance driving): slow down
and, if the warning light stays on, stop the car.
Wait for 2 or 3 minutes with the engine running
and slightly accelerated to further favour the
coolant circulation. Then stop the engine. Check
the correct coolant level as described above.
IMPORTANT Over demanding routes, it is
advisable to keep the engine on and slightly
accelerated for a few minutes before switching it
off.
