temperature sensor Alfa Romeo Giulietta 2014 Owner's Manual

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.
33

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

60) Parking and other dangerous
manoeuvres are, however, always
the driver’s responsibility. While
carrying out these manoeuvres,
always make sure that no people
(especially children) or animals are
in the area concerned. The
parking sensors are an aid for the
driver, but the driver must never
allow their attention to lapse
during potentially dangerous
manoeuvres, even those executed
at low speeds.
REFUELLING THE
CARStop the engine before refuelling.
PETROL ENGINES
Only use unleaded petrol 95 R.O.N.
compliant with the European
specification EN228. The petrol octane
rating (R.O.N.) must not be lower than
95. In order to prevent damage to
the catalytic converter never introduce
even the smallest amount of leaded
petrol, even in the event of an
emergency.
DIESEL ENGINES
Use only diesel fuel compliant with
European specification EN590. The use
of other products or mixtures may
damage the engine beyond repair and
consequently invalidate the warranty,
due to the damage caused.Operation at low
temperatures
If the outside temperature is very low,
the diesel thickens due to the formation
of paraffin clots with consequent
defective operation of the fuel supply
system.
In order to avoid these problems,
different types of diesel are distributed
according to the season: summer type,
winter type and arctic type (cold,
mountain areas).
If refuelling with diesel whose
specifications are not suitable for the
usage temperature, it is advisable
to mix TUTELA DIESEL ART additive in
the proportions shown on the container
with the fuel. Pour the additive into
the tank before the fuel.
When using or parking the car for a
long time in the mountains or cold
areas, it is advisable to refuel using
locally available fuel. In this case, it is
also advisable to keep the tank over
50% full.

PROTECTING THE
ENVIRONMENTThe following devices are used for
reducing petrol fuel engine emissions:
catalytic converter, oxygen sensors and
evaporation control system
The following devices are used for
reducing diesel fuel engine emissions:
oxidising catalytic converter, exhaust
gas recirculation system (EGR) and
particulate filter (DPF).
62)
DIESEL PARTICULATE
FILTER (DPF)
(Diesel Particulate Filter)
(for versions/markets, where provided)
The Diesel Particulate Filter is a
mechanical filter, integral to the exhaust
system, that physically traps carbon
particles present in the exhaust gases
of diesel engines.
The diesel particulate filter is needed to
eliminate almost all carbon particle
emissions in compliance with
current/future regulations and
standards.During standard use of the vehicle, the
engine control unit records a set of data
(e.g.: travel time, type of route,
temperatures, etc.) and it will then
calculate how much particulate has
been trapped by the filter.
Since this filter physically traps
particulate, it should be periodically
regenerated (cleaned) at regular
intervals by burning carbon particles.
The regeneration procedure is
controlled automatically by the engine
management control unit according
to the filter conditions and vehicle use
conditions.
During the regeneration there may be a
limited increase in the engine idle
speed, fan activation, a limited increase
in fumes and high temperatures at the
exhaust.
These are not faults; they do not impair
normal car performance or damage
the environment. If the dedicated
message is displayed, see contents of
"Warning lights and messages"
paragraph, in chapter "Knowing the
instrument panel".
WARNING
62) The catalytic converter and
particulate filter (DPF) reach very
high temperatures during
operation. Therefore do not park
the car on flammable materials
(e.g. grass, dry leaves, pine
needles, etc.): fire hazard.
