SPEEDOMETER (SPEED INDICATOR)
This shows the speed of the car.
REV COUNTER
This indicates the engine rpm.
FUEL LEVEL GAUGE
This shows the amount of fuel left in the fuel tank.
0 - tank empty.
1 - tank full
The warning light in the gauge lights up when there are only 8 to
10 litres of fuel remaining in the tank; refuel at the earliest op-
portunity.
ENGINE COOLANT TEMPERATURE INDICATOR
This gauge indicates the temperature of the engine coolant. The
warning light on the indicator lights up to indicate an increase in
coolant temperature; in the event of this happening, switch off the
engine and contact an Alfa Romeo Authorised Service Provider.
INSTRUMENT PANEL WARNING LIGHTS
General warnings
The warning lights come on in conjunction with a dedicated mes-
sage and/or a buzzer where appropriate. These indications are
brief and precautionary and as such must not be considered as
exhaustive and/or alternative to the information contained in the
Owner’s Handbook, which you are recommended to read careful-
ly in all cases. Always refer to the information in this chapter in the
event of a failure signal.
Low brake fluid level (red)
When the ignition key is turned to MAR, the warning
light turns on but should go off after a few seconds.
The warning light (or symbol on the display) comes on
when the level of the brake fluid in the reservoir falls below the
minimum level due to possible leaks in the circuit.
A specific message will be shown on the display.
Handbrake on (red)
When the ignition key is turned to MAR, the warning light turns
on but should go off after a few seconds. The warning light (or
symbol on the display) comes on when the handbrake is on. If
the car is moving a buzzer is also triggered.
IMPORTANT If the warning light comes on with the vehicle in mo-
tion, check that the handbrake is not engaged.

Hot engine coolant (red)
When the ignition key is turned to MAR, the warning
light turns on but should go off after a few seconds.
The warning light turns on when the engine is over-
heated. A specific message will be shown on the display.
If the warning light comes on, proceed as follows:
❍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 not, wait for a few minutes 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.
Also visually check for leaks. If the warning light comes on again
at the next engine start-up, contact Alfa Romeo Authorized Ser-
vices.
❍if the car is used under demanding conditions (e.g. towing trail-
ers uphill or fully loaded): slow down and, if the light stays on,
stop the car. Stop for two or three minutes with the engine run-
ning and slightly accelerated to assist better coolant circulation.
Then switch the engine off. Check correct fluid level as described
above.
IMPORTANT On particularly demanding journeys, it is advisable to
keep the engine on and slightly accelerated for a few minutes be-
fore switching it off.
u
Door open (red)
(for versions/markets, where provided)
The warning light (or symbol on the display) comes
on when one or more doors or the boot are not perfectly
closed. An acoustic signal is activated with the doors open and
the car moving. On some versions, the warning light (or symbol
on the display) also lights up when the bonnet is not perfectly
closed.´
EOBD/injection system fault (amber)
Under normal conditions, the warning light comes on
when the ignition key is turned to MAR, but should
go off as soon as the engine is started.
If the warning light remains on or comes on whilst driving, that
means that the injection system is not working properly; in partic-
ular, if the warning light comes on constantly, this indicates a mal-
function in the supply/ignition system that could cause excessive
exhaust emissions, a possible loss of performance, poor driveabil-
ity and high fuel consumption.
A specific message is displayed on certain versions.
Under these conditions, you can continue travelling at moderate
speed without demanding excessive effort from the engine. Pro-
longed use of the car with the warning light on may cause dam-
age. Contact Alfa Romeo Authorized Services as soon as possible.
The warning light goes out after the fault disappears, but the in-
dication is stored in the system.U

START&STOP
Manual climate control system
The system will remain set to the air flow setting made by the user
when the Start&Stop function is operated (engine off when speed
is zero). Cooling and heating in the passenger compartment is not
guaranteed in these conditions because the compressor and the
engine coolant pump are both stopped. To privilege climate con-
trol system operation, press the button on the dashboard to turn
the Start&Stop function off.
NOTAIn particularly severe climate conditions it is recommended
to limit the use of the Start&Stop function to prevent the com-
pressor from continuously switching on and off, with following fa-
st window misting and accumulation of humidity with unpleasant
smells in the passenger compartment.
SYSTEM MAINTENANCE
Operate the climate control system for at least 10 minutes every
month during the winter. Have the system checked by Alfa Romeo
Authorized Services before the summer.
A0K0083m
Four other positions are provided (see diagram below):
v(A Position) Air flow distribution between centre/side dash-
board vents, rear vent and windscreen and front side window
demisting/defrosting vents. This distribution setting ventilates
the passenger compartment and prevents the windows from
misting up.
u(B Position) Air flow distributed between foot well vents and
windscreen and front side window defrosting/demisting vents.
This distribution setting allows warms up the passenger com-
partment and prevents the windows from misting up.
w(C Position) Air flow distribution between footwell vents
(warmer air) and centre/side dashboard vents and rear vent
(cooler air).
-(D Position) Automatic demisting/defrosting activation (see
description of the previous pages).

CLIMATE CONTROL SYSTEM COMPRESSOR
Press C to turn the compressor on/off (the LED on the button will
light up when the compressor is on). The system remembers that
the compressor has been switched off, even after the engine has
stopped.
When the compressor is switched off the system deactivates air re-
circulation to prevent the windows from misting up and deactivates
the AQS function. In this case, although the system is capable of
maintaining the required temperature, the AUTO LED will go out.
The temperatures will flash for a few seconds if the required tem-
perature cannot be maintained.
To restore automatic control for switching on the climate control
compressor, press C button again or press the AUTO button.
With compressor off:
❍if the outside temperature is higher than the set one, the sys-
tem will not be able to satisfy the request. The temperature
value will then flash on the display for a few seconds;
❍the fan speed can be manually reset.
When the compressor is on and the engine is running, manual ven-
tilation cannot drop under the maximum speed (only one LED on).
IMPORTANT With the climate control compressor off, it is not pos-
sible to admit air into the passenger compartment with a tempera-
ture below the outside temperature; moreover, under certain envi-
ronmental conditions the windows could mist up very quickly since
the air cannot be dehumidified.
RAPID WINDOW DEMISTING/DEFROSTING
(MAX-DEF function)
Press-to turn windscreen and side window demisting/defrosting
function on (LED on button lit). The climate control system carries
out the following operations:
❍switches on the climate control compressor when climatic con-
ditions allow;
❍turns air recirculation off;
❍sets maximum air temperature (HI) in both zones;
❍sets proper fan speed according to the engine coolant tem-
perature;
❍directs air flow to the windscreen and front side windows vents;
❍the heated rear windscreen is turned on
❍shows fan speed (LED G lit).
IMPORTANT The MAX-DEF function will remain on for approximately
3 minutes from when the engine coolant reaches adequate tem-
perature.
The LED on the AUTO button will go out when the function is on.
With the function activated the only possible manual adjustments
are adjusting the fan speed and the turning the heated rear wind-
screen off. By pressing B, C,
-or AUTO buttons, the climate
control system will turn the MAX-DEF off.

NOTEWhen the Start&Stop function is active (engine off and
vehicle speed zero), the automatic recirculation management is
turned off always taking air in from outside, to reduce the proba-
bility of window misting up (as the compressor is off).
SUPPLEMENTARY ELECTRIC HEATER
(for versions/markets where provided)
This device speeds up passenger compartment warming when it is
very cold. The additional heater turns off automatically after reach-
ing the required comfort conditions.
Automatic dual zone climate control system
(for versions/markets, where provided)
The supplementary electric heater is operated automatically ac-
cording to environmental conditions and when the engine is run-
ning.
Manual climate control system
The supplementary heater is activated automatically by turning A
knob to the end of the red section and setting the fan (knob B)
to at least the 1
stspeed.
IMPORTANT NOTES
The heater only works if the outside temperature and engine coolant
temperature are low.
The heater will not activate if the battery voltage is too low.
START&STOP
Automatic climate control system
The automatic climate control system manages the Start&Stop
function (engine off when speed is zero) to ensure adequate com-
fort inside the passenger compartment.
Specifically, the Start&Stop function is turned off when the weath-
er is particularly hot or cold to guarantee an adequate level of com-
fort inside the passenger compartment; therefore, the engine will
not be stopped during these transient conditions, even if the speed
is zero.
When the Start&Stop is on and the engine is off at zero speed,
the climate control system will turn the engine back on if the in-
side temperature conditions should rapidly deteriorate (or if the
user asks for maximum cooling – LO – or quick demisting –
MAX-DEF).
With the Start&Stop function on and engine off at zero speed,
air flow is reduced to the minimum to main comfort conditions in-
side the passenger compartment as long as possible when the sys-
tem is in AUTO mod (LED N on).
The climate control system attempts to manage the discomfort
caused by the engine stopping (compressor and engine coolant
pump off) but operation of the climate control system can be priv-
ileged by turning the Start&Stop off by pressing the button on
the dashboard.
NOTEIn particularly severe climate conditions it is recommen-
ded to limit the use of the Start&Stop function to prevent the com-
pressor from continuously switching on and off, with following fa-
st window misting and accumulation of humidity with unpleasant
smells in the passenger compartment.

It is advisable not to demand maximum perfor-
mance from your car (e.g. excessive acceleration,
long distances at top rpm, excessively intense brak-
ing, etc.) when it is first used.
Remember that the brake servo and electro-
mechanical power steering are not operational un-
til the engine has been started, therefore much
more effort than usual is required on the brake pedal and
steering wheel.
Never jump start the engine by pushing, towing or
driving downhill. These manoeuvres may damage
the catalytic converter.
When the engine is switched off never leave the
key in the MAR position to prevent useless cur-
rent absorption from draining the battery.
HOW TO WARM UP THE ENGINE
AFTER IT HAS JUST STARTED
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 temperature indicator
starts moving.
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 especially damaging to tur-
bocharged engines.
