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.

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.

REGULAR CHECKS
Every 1,000 km or before long journeys, check and top up the fol-
lowing if necessary:
❍engine coolant level, brake fluid and windscreen washer fluid
❍tyre pressure and condition;
❍operation of lighting system (headlights, direction indicators,
hazard lights, etc.);
❍operation of the windscreen wiper/washer system, position
and wear of windscreen/rear window wiper blades;
Check and top up, if required, the engine oil level every 3,000 km.
DEMANDING USE OF THE CAR
If you use the car mainly under one of the following conditions:
❍trailer or caravan towing;
❍dusty roads;
❍short (less than 7-8 km) and repeated journeys in sub-zero
temperatures;
❍frequent engine idling, travelling long distances at low speeds
or long term inactivity;
perform the following inspections more frequently than shown on
the Scheduled Servicing Plan:
❍check front disc brake pad condition and wear;
❍check cleanliness of bonnet and boot locks, as well as cleanli-
ness and lubrication of linkages;
❍visually inspect the conditions of: engine, gearbox, transmis-
sion, pipes and tubes (exhaust - fuel - brakes), rubber parts
(boots, sleeves, bushes, etc.);
❍check battery charge and liquid level (electrolyte);
❍visually inspect the condition of auxiliary drive belts;
❍check and if necessary change engine oil and oil filter;
❍check pollen filter and replace it, if required;
❍check air filter and replace, if required.
