amberGLOW PLUG HEATING/GLOW PLUG
HEATING FAILURE (diesel versions)
This warning light switches on when the key is
turned to MAR-ON. It will switch off as soon as
the heater plugs have reached a preset
temperature. The engine can be started as soon
as the warning light switches off.
IMPORTANT In mild or high temperature
conditions, the warning light comes on for a very
short time only.
Glow plug preheating failure
The warning light will flash (a message will appear
on the display, on some versions) to indicate a
fault in the glow plugs preheating system.Contact an Alfa Romeo Dealership as soon as
possible.
amberWATER IN DIESEL FILTER (diesel versions)
The warning light remains on constantly when
driving (together with a message in the display),
to indicate the presence of water in the diesel
filter.

IMPORTANT
13) If, turning the ignition key to MAR-ON, thewarning light does not turn on or if it turns on steadily or flashing
when travelling (on certain versions together with the message on the display), contact an Alfa Romeo Dealership
as soon as possible.
IMPORTANT
14) The presence of water in the fuel supply system circuit may cause severe damage to the injection system and
irregular engine operation. If the
warning light comes on in the instrument panel (together with a message in the
display) contact an Alfa Romeo Dealership as soon as possible to bleed the system. If the above indications come
on immediately after refuelling, water has probably been poured into the tank: turn the engine off immediately and
contact an Alfa Romeo Dealership.

Warning lights on
panelWhat it means What to do
amberDPF CLEANING (particulate trap) in progress
(diesel versions with DPF only)
When the key is turned to MAR-ON, the warning
light switches on but it should switch off after a
few seconds. The warning light switches on
constantly to indicate that the DPF system needs
to eliminate the trapped pollutants (particulate)
through the regeneration process.
The warning light does not come on during every
DPF regeneration, but only when driving
conditions require that the driver is notified. To
turn off the warning light, keep the car in motion
until the regeneration process is over.
On average, the process lasts 15 minutes.
Optimal conditions for completing the process are
achieved by travelling at 60 km/h with engine
speed above 2000 rpm.
When this warning light switches on, it does not
indicate a car failure and thus it should not be
taken to a workshop. On some versions, together
with the warning light switching on, the display
shows a dedicated message.

KNOWING THE INSTRUMENT PANEL
WARNING
69) Always drive at a speed appropriate to the traffic conditions, the weather and traffic regulations. The engine can be
stopped even if the DPF warning light is on: however, repeated interruptions of the regeneration process could cause
premature deterioration of the engine oil. For this reason, always wait until the warning light switches off before
stopping the engine as described above. It is not advisable to complete DPF regeneration with the car stationary.

panelWhat it means What to do
amberELECTRONIC STABILITY CONTROL (ESC)
SYSTEM
When the ignition key is turned to MAR-ON, the
warning light switches on, but should switch off
as soon as the engine is started.
Intervention by the system is indicated by the
flashing of the warning light: it indicates that the
car is in critical stability and grip conditions.
If the warning light (or symbol on the display)
does not switch off, or if it stays on with the
engine running, this means that an ESC system
fault is present.
On some versions, the display shows the
dedicated message.Contact an Alfa Romeo Dealership as soon as
possible to have the problem diagnosed and
resolved.

SYSTEM
ASR system failure
When the ignition key is turned to MAR-ON, the
warning light switches on, but should switch off
as soon as the engine is started.
The warning light will flash while driving to indicate
that the ASR system is intervening.
If the warning light (or symbol on the display)
does not switch off, or if it stays on with the
engine running, this means that an ASR system
malfunction has been detected.
On some versions, the display shows the
dedicated message.In this case, contact an Alfa Romeo Dealership as
soon as possible.
Hill Holder system failure
The warning light switches on together with the
symbol and corresponding message on the
display to indicate Hill Holder system failure.In this case, contact an Alfa Romeo Dealership as

KNOWING THE INSTRUMENT PANEL

Driver
If the driver is the only occupant and
their seat belt is not fastened, when 20
km/h is exceeded or when travelling
at a speed between 10 and 20 km/h for
longer than 5 seconds, an acoustic
signal cycle will be started for the front
seats (continuous acoustic signal for
6 seconds followed by a 90 second
beep). The warning light will flash.
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 situation applies to the front
passenger, with the difference that the
warning light turns green and the
indication is also interrupted when the
passenger leaves the car.If both front seat belts are unfastened a
few seconds apart while the car is
travelling, the acoustic signal will refer
to the most recent event and the two
warning lights will proceed with the
visual indication independently.
REAR SEATS (warning
light no. 2, no. 3 and no.
4)
For the rear seats, the reminder cycle is
only activated when any seat belt is
unfastened (flashing red).
In this condition, the warning light for
the seat belt which has been
unfastened will flash (red) for
approximately 30 seconds. An acoustic
signal is also emitted.
The visual indication (flashing red) will
start and stop 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.
The rear seat warning lights will switch
off, regardless of the state of the belt
(red or green) approximately 30
seconds after the last signal.IMPORTANT
The warning lights are all off if all seat
belts (front and rear) are already
fastened when the ignition key is turned
to MAR.
All warning lights switch on when at
least one belt changes from fastened to
unfastened or vice versa.

SAFETY
FRONT SEATS (warning
light no. 1 = driver and
no. 5 = passenger)

96) When the ignition key is in and
turned in the MAR-ON position
and the engine is off, the airbags
may deploy if the car is crashed
by another moving vehicle.
Therefore, even if the car is
stationary, when an active
passenger airbag is fitted, DO
NOT install rear 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 airbag
when a rear 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 avoid 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 a collision. Non-
deployment in such cases does
not indicate a system malfunction.97) When the ignition key is turned
to MAR-ON, the
warning light
turns on (front airbag on
passenger's side enabled) and
blinks for a few seconds to remind
that the passenger airbag will
activate in the event of a collision.
Then it turns off.
98) The front airbags deploy in the
event of more severe collisions
than those required for deploying
the pretensioners. When the
impact is between the two
deployment thresholds, it is
normal that pretensioners only are
engaged.
99) 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.

STARTING THE
ENGINE
PROCEDURE FOR
PETROL VERSIONS
Proceed as follows:
❒engage the handbrake and place the
gear 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.
IMPORTANT INFORMATION
100) 101)
102)
16) 17) 18)
❒If the engine does not start at the first
attempt, return the ignition key to
STOP before repeating the starting
procedure.
❒If, when the ignition key is at
MAR-ON, the
instrument panel
warning light (or the symbol on the
display) stays on together with the
warning light, turn the key to
STOP and then back to MAR-ON. If
the warning light (or the symbol on
the display) remains on, 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 at MAR
when the engine is stopped.
PROCEDURE FOR DIESEL
VERSIONS
Proceed as follows:
19)
❒engage the handbrake and place the
gear lever in neutral;
❒turn the ignition key to MAR-ON: the
warning lights
andon the
instrument panel will turn on (for
versions/markets, where provided);
❒wait for the warning lights to switch
off;
❒fully depress the clutch pedal,
without touching the accelerator;
❒turn the ignition key to AVV as soon
as 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.
WARMING UP THE
ENGINE JUST AFTER IT
HAS STARTED
Proceed as follows:
❒drive off slowly, letting the engine turn
at medium speed without
accelerating abruptly;❒do not demand full performance at
first. It is advisable to wait until the
engine coolant temperature indicator
starts moving.
STOPPING THE ENGINE
Turn the ignition key to STOP while the
engine is idling.
IMPORTANT After a demanding drive,
before turning the engine off you should
let it idle so that the temperature in the
engine compartment decreases.
WARNING
100) 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.
101) 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.
102) Do not start the engine by
pushing, towing or driving
downhill. These manoeuvres may
damage the catalytic converter.
148
STARTING AND DRIVING

IMPORTANT
16) In the first period of use, we
recommend not to demand
maximum performance from the
car (for instance excessive
accelerations, extended travel at
maximum speed, sudden braking,
etc.).
17) With the engine off, do not leave
the key in the ignition switch on
MAR-ON to prevent draining
the battery.
18) A quick burst on the accelerator
before turning off the engine
serves absolutely no practical
purpose; it wastes fuel and is
especially damaging to
turbocharged engines.
19) If the
warning light flashes
for about 1 minute after starting
or during prolonged cranking, this
indicates a fault in the glow plug
preheating system. If the engine
starts, you may use the car
normally, but should contact an
Alfa Romeo Dealership as soon as
possible.
PARKING
Always remove the ignition key when
leaving the car.
When parking and leaving the car,
proceed as follows:
❒engage a gear (1st gear if parked
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 it, pull lever A fig. 126
upwards until the car is secured.
When the handbrake is engaged and
the ignition key is at MAR-ON, the
warning light will switch on in the
instrument panel.To release it, raise lever A slightly, hold
down button B and lower the lever:
the
warning light on the instrument
panel switches off.
103) 104)
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.
