coolant Alfa Romeo Giulietta 2014 Owner's Manual

There are also another 4 positions (see
diagram below fig. 29):
Position A: Air flow distribution
between centre/side dashboard
vents, rear diffuser and windscreen
and front side window demisting/
defrosting diffusers. This
distribution setting ventilates the
passenger compartment well and
prevents the windows from misting
up.Position B: Air flow distributed
between footwell diffusers and
windscreen and front side window
defrosting/demisting diffusers.
This distribution setting allows the
passenger compartment to warm
up efficiently and prevents the
windows from misting up.
Position C: Air flow distribution
between footwell diffusers (hotter
air) and centre/side dashboard
diffusers and rear diffuser (cooler
air).Position D: Automatic
demisting/defrosting activation
(see description in previous
pages).
START&STOP
Manual climate control
If the Start&Stop function is activated
(engine off when the car speed is
0 km/h), the system keeps the air flow
selected by the user.
In these conditions, the compartment
cooling and heating cannot be
guaranteed, as the compressor stops
with the engine coolant pump.
The Start&Stop function can be
deactivated to enhance the operation of
the climate control system by pressing
the dedicated button on the
dashboard.SERVICING
MAINTENANCE
In winter, the climate control system
must be turned on at least once a
month for about 10 minutes.
Have the system inspected at an Alfa
Romeo Dealership before the summer.

With the compressor on and the engine
running, manual ventilation cannot be
lower than the minimum speed (only
one LED lit).
IMPORTANT With the compressor off,
air cannot be introduced to the
passenger compartment with
a temperature lower than the outside
temperature. Moreover, under certain
environmental conditions, windows
could mist up rapidly since the air is not
dehumidified.
RAPID WINDOW
DEMISTING/DEFROSTING
(MAX-DEF function)
Press the
button to activate (LED
on button on) the windscreen and side
windows demisting/defrosting function.
The climate control system carries out
the following operations:
❒switches on the air conditioning
compressor when climatic conditions
are suitable;
❒deactivates air recirculation;
❒sets maximum air temperature (HI) in
both zones;
❒sets fan speed according to the
engine coolant temperature;
❒directs air flow to windscreen and
front side windows diffusers;❒activates the heated rear window.
❒displays the fan speed (LED G lit).
IMPORTANT The MAX-DEF function
remains on for about 3 minutes from
when the engine coolant reaches the
appropriate temperature.
When the function is activated, the LED
on the AUTO button switches off.
With the function activated the only
possible manual adjustments are
adjusting the fan speed and turning the
heated rear window off.
When the B, C,
or AUTO buttons
are pressed, the climate control system
will turn the MAX-DEF off.
HEATED REAR WINDOW
DEMISTING/DEFROSTING
Press the
button to activate (LED
on button on) heated rear window
demisting/defrosting.
This function switches off automatically
after about 20 minutes or when the
engine is turned off. It is not switched
on automatically the next time the
engine is started.
For versions/markets where provided,
press thebutton to activate
demisting/defrosting of exterior rear
view mirrors and heated nozzles (for
versions/markets, where provided).IMPORTANT Do not affix stickers to the
inside of the heated rear window over
the heating filaments, to avoid damage
that might cause them to stop working
properly.
Thermal comfort
windscreen
(for versions/markets, where provided)
Some versions feature a thermal
comfort windscreen which, with the car
exposed to the sun, reduces the
temperature in the passenger
compartment relative to the outside
temperature, thus ensuring greater
comfort.
Humidity sensor
(for versions/markets, where provided)
The humidity sensor helps to prevent
the windows from misting up. For
full functionality, it is advisable to
activate the AUTO function (LED N on).
When the outside temperature is low,
the system could automatically turn the
compressor on and turn air recirculation
off for safer driving.

SWITCHING OFF/ON THE
CLIMATE CONTROL
SYSTEM
Switching off the
climate control system
Press the
button (LED on button off).
With climate control off:
❒air recirculation is on, thus isolating
the passenger compartment from
the outside;
❒the compressor is off;
❒the fan is off;
❒the heated rear window can be
switched on or off;
❒the AQS (Air Quality System) function
cannot be activated.
IMPORTANT The climate control
system control unit stores the
temperatures set before the system
was switched off and restores them
when any button of the system is
pressed (except for button D).
Switching on the climate
control system
To switch on the climate control system
in fully automatic mode press the AUTO
button.START&STOP
Automatic Climate
Control
The dual zone automatic climate control
manages the Start&Stop function
(engine off when the car speed is zero)
to guarantee a suitable comfort inside
the car.
Specifically, the Start&Stop function is
turned off when the weather is
particularly hot or cold to guarantee an
adequate level of comfort 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 function is active
(engine off at zero car speed), the
climate control system will request
restarting of the engine if the inside
temperature conditions rapidly
deteriorate (or if the user requests
maximum cooling – LO – or quick
demisting – MAX DEF).
With the Start&Stop function on (engine
off at zero speed), air flow is reduced
to the minimum to maintain comfort
conditions inside the passenger
compartment as long as possible when
the system is in AUTO mode (LED N
on).The climate control system control unit
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 enhanced by turning
the Start&Stop off by pressing the
dedicated button on the dashboard.
NoteIn particularly severe climate
conditions it is recommended to limit
the use of the Start&Stop function
to prevent the compressor from
continuously switching on and off, with
consequent rapid misting of the
windows and accumulation of humidity
with unpleasant smells in the passenger
compartment.
NoteWhen the Start&Stop function is
on (engine off and vehicle speed zero),
the automatic recirculation
management is turned off always taking
air in from outside, to reduce the
probability of window misting up (as the
compressor is off).

GETTING TO KNOW YOUR CAR

ADDITIONAL HEATER
(for versions/markets, where provided)
This allows the passenger
compartment to be heated more
quickly in cold weather conditions. The
additional heater turns off automatically
after the required comfort conditions
are achieved.
Automatic dual zone
climate control system
(for versions/markets, where provided)
The additional heater activates
automatically depending on the
environmental conditions and with
engine started.
Manual climate control
system
The additional heater activates
automatically when knob A is turned to
the end of the red section and the fan
is set to at least 1
stspeed.
IMPORTANT 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.
IMPORTANT
2) The climate control system
detects the passenger
compartment temperature with a
mean radiant temperature sensor
fitted in a cover under the internal
rear view mirror. Obstructing the
field of view of this sensor with
any object could cause the
climate control system to operate
with less than optimal efficiency
EXTERNAL LIGHTS
IN BRIEF
The left stalk fig. 31 operates most of
the external lights. The external
lights can only be switched on when
the ignition key is at MAR-ON.
The instrument panel and the
dashboard and central tunnel
controls will light up together with the
external lights.31

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.
The warning light in the gauge lights up
when there are only 8 to 10 litres of
fuel remaining in the tank; if this
happens, refuel as soon as possible.
Do not travel with the fuel tank almost
empty: any gaps in fuel delivery could
damage the catalytic converter.ENGINE COOLANT
TEMPERATURE
INDICATOR
The needle shows the temperature of
the engine coolant and starts supplying
indications when the fluid temperature
exceeds approx. 50°C.
Under normal conditions, the needle
assumes different positions within
the scale depending on the usage
conditions.
The warning light turns on to indicate
an overheating of the engine coolant. In
this case, stop the engine and contact
an Alfa Romeo Dealership.
TRIP COMPUTER
IN BRIEF
The Trip computer is used to display
information on car operation when
the key is turned to MAR.
This function is characterised by two
separate memories, called "Trip A"
and "Trip B", where the car's
"complete missions" (journeys) are
recorded in a reciprocally
independent manner.
Both memories can be reset: i.e. start
of a new journey.
“Trip A” is used to display the figures
relating to:
❒Range
❒Distance travelled
❒Average fuel consumption
❒Instant fuel consumption
❒Average speed
❒Trip time (driving time).
“Trip B” may be used to display the
figures relating to:
❒Distance travelled B
❒Average consumption B

KNOWING THE INSTRUMENT PANEL

Warning lights on
panelWhat it means What to do
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.
