Air distribution selection
Air flow to the windscreen and front side window vents to demist/defrost them.
Air flow at central and side dashboard vents to ventilate the chest and the face during the hot season.
Air flow to the front and rear footwell vents. This air distribution setting heats the passenger compartment most quickly, giving
a prompt sensation of warmth
IMPORTANT In warm-humid weather conditions, using cold air on the windscreen may cause external condensation.
In AUTO mode, the climate control system automatically manages air distribution (the LEDs on buttons H are off). When set
manually, the air distribution is indicated by the LEDs on the selected buttons switching on.
You can also set a combination of the air distribution settings described above. In combined function mode the relevant function is
enabled simultaneously with those already set by pressing the corresponding button. If a button whose function is already active is
pressed, the operation is cancelled and the corresponding LED switches off. To restore automatic control of the air distribution after
a manual selection, press the AUTO button.
Start&Stop
The automatic dual zone climate control system manages the Start&Stop system (engine off when car speed is 0 km/h) to ensure
adequate comfort inside the car. When the Start&Stop system is on (engine off and car at a standstill), the automatic recirculation
management is turned off always taking air in from outside, to reduce the probability of the windows misting up (as the compressor
is off).
IMPORTANT
2)The system uses a coolant that is compatible with the laws in force in the countries where the vehicle is sold, R134a or R1234yf (indicated on a
specific plate in the engine compartment). The use of other coolants affects the efficiency and condition of the system. Also the compressor
coolants used must be compatible with the indicated coolant.

Warning lights on
panelWhat it means What to do
ENGINE COOLANT TEMPERATURE TOO HIGH
The warning light switches on when the ignition key is
turned to MAR, but it should switch off after a few
seconds. The warning light turns on when the engine is
overheated.
The display shows the dedicated message.In normal driving conditions: stop the car, switch off the
engine and check that the water level in the reservoir is
not below the MIN mark. In this case, 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 itself. 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 vehicle is used under demanding conditions: (e.g. in
high-performance driving): slow down and, if the warning
light stays on, stop the vehicle. Wait for 2 or 3 minutes
with the engine running and slightly accelerated to further
favour the coolant circulation. Then stop the engine. Check
that the coolant level is correct 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.
ALFA TCT FAILURE
(for versions/markets, where provided)
The warning light switches on when the ignition key is
turned to MAR, but it should switch off after a few
seconds.
The warning light flashes (together with a message in the
display and an acoustic signal) to indicate that the gearbox
is faulty.
The warning light can switch on even in the case of
transmission overheating, after a particularly demanding
use. In this case an engine performance limitation is
carried out.Contact an Alfa Romeo Dealership as soon as possible.
If it is necessary to start the engine with a transmission
failure, follow the procedure described in the "Alfa TCT"
paragraph, in chapter "Starting and driving".
SPEED LIMIT EXCEEDED
(for versions/markets, where provided)
The warning light switches on when the car exceeds the
speed limit value set in the Setup Menu (e.g. 120 km/h).
On some versions a message is shown along with a symbol
on the display, and an acoustic signal is emitted.
47

PERIODIC CHECKS
Every 1,000 km or before long journeys,
check and, if necessary, top up the
following:
engine coolant, brake fluid and
windscreen washer fluid level;
tyre inflation pressure and condition;
operation of lighting system
(headlights, direction indicators, hazard
warning lights, etc.);
operation of screen wash/wipe system
and positioning/wear of windscreen/
rearscreen wiper blades
Check and top up, if required, the engine
oil level every 3,000 km.
IMPORTANT To find out the correct oil
quantity, always check using the dipstick.
Carry out the check with the vehicle
parked on level ground.
DEMANDING USE OF THE CAR
If the vehicle is used mainly under one of
the following conditions:
towing a trailer or caravan;
dusty roads;
short, repeated journeys (less than
7-8 km) at sub-zero outside
temperatures;
engine often idling or driving long
distances at low speeds or long periods
of inactivity;
the following checks must be carried out
more often than indicated in the
Scheduled Servicing Plan:
check front disc brake pad condition
and wear;
check cleanliness of bonnet and
luggage compartment locks, cleanliness
and lubrication of linkage;
visually inspect condition of: engine,
gearbox, transmission, pipes and hoses
(exhaust - fuel system - brakes) and
rubber elements (boots - sleeves - bushes
- etc.);
check battery charge and battery fluid
level (electrolyte);
visually inspect conditions of the
accessory drive belts;
check and, if necessary, change engine
oil and replace oil filter;
check and, if necessary, replace pollen
filter;
check and, if necessary, replace air
cleaner.

SERVICING AND MAINTENANCE

ENGINE OIL
Check that the oil level is between the
MIN and MAX references on the dipstick
3.
If the level of the oil is close to or below
the MIN mark, add oil via the filler fitting
2 until the MAX mark is reached.
131)42)
Take out the engine oil dipstick 3, clean it
with a lint-free cloth and reinsert it.
Extract it again and check that the level is
between the MIN and MAX marks on the
dipstick.
Engine oil consumption
43)3)
The maximum engine oil consumption is
usually 400 grams every 1000 km. When
the car is new, the engine needs to be run
in; therefore the engine oil consumption
can only be considered stabilised after
the first 5000 - 6000 km.
ENGINE COOLANT FLUID
If the level is too low, unscrew the cap
1 of reservoir and add the fluid described
in the "Technical Specifications" chapter.
44)132)
WINDSCREEN / REAR WINDOW
WASHING FLUID
If the level is too low, raise the reservoir
cap 6 and add the fluid described in the
"Technical Specifications" chapter.
133) 134)
IMPORTANT The headlight washer
system will not operate when the fluid
level is low, even though the
windscreen/rear window washer
continues to operate. For
versions/markets, where provided, there
is a reference notch on the dipstick (see
previous pages): ONLY the
windscreen/rear window wiper operates
with the level below this reference.
BRAKE FLUID
Check that the fluid is at the max. level.
If the fluid level in the reservoir is too low,
undo the reservoir cap 4 and add the fluid
described in the "Technical
Specifications" chapter.
45)135) 136)
AUTOMATIC TRANSMISSION
ACTIVATIONSYSTEM OIL
(for versions/markets, where provided)
The transmission control oil level should
only be checked at an Alfa Romeo
Dealership.
4)
IMPORTANT
41)Be careful not to confuse the various
types of fluids while topping up: they are not
compatible with each other! Topping up with
an unsuitable fluid could severely damage
your vehicle.42)The oil level must never exceed the MAX
reference.
43)Do not add oil with specifications other
than those of the oil already in the engine.
44)Use a fluid of the same type as that
already present in the reservoir for any
topping up of the engine cooling system. The
fluid cannot be mixed with other types of
antifreeze fluids. In the event of topping up
with an unsuitable product, under no
circumstances start the engine and contact
an Alfa Romeo Dealership.
45)Prevent brake fluid, which is highly
corrosive, from coming into contact with
painted parts. Should it happen, immediately
wash with water.
WARNING
129)Never smoke while working in the
engine compartment: gas and inflammable
vapours may be present, with the risk of fire.
130)Be very careful when working in the
engine compartment when the engine is hot:
you may get burned. Do not get too close to
the radiator cooling fan: the electric fan may
start; danger of injury. Scarves, ties and
other loose clothing might be pulled by
moving parts.
131)If the engine oil is being topped up, wait
for the engine to cool down before loosening
the filler cap, particularly for vehicles with
aluminium cap (where provided). WARNING:
risk of burns!
