air condition Alfa Romeo Giulia 2018 Owner's Manual

The feature is especially useful for road
splash or over spray from the windshield
washers of the vehicle ahead. Rotate the
end of the multifunction lever to one of
four settings to activate this feature.
The sensor has an adjustment range that
varies progressively from wiper still
(no stroke) when the windshield is dry, to
wiper at continuous speed (fast
operation) with intense rain.
Activation
Rotating the wiper switch to position
oractivates the rain sensor.
The activation of the rain sensor system
is done by tapping the wiper stalk
upwards while the switch is in the
orposition.
The variation in sensitivity during rain
sensor operation is also signaled by a
stroke of the wiper (command acquired
and implemented). This stroke is also
executed with the windshield dry.
If the windshield washer is used with the
rain sensor activated, the normal washing
cycle is performed, after which the rain
sensor resumes its normal automatic
operation.
Note: Keep the glass in the sensor area
clean. Deactivation
Use the wiper switch or cycle the ignition
to STOP.
In the event of malfunction of the rain
sensor while it is active, the windshield
wiper operates intermittently at a speed
consistent with the sensitivity setting of
the rain sensor, whether or not there is
rain on the glass for as long as the sensor
failure is indicated on the display.
The sensor continues to operate and it is
possible to set the windshield wiper to
continuous mode
or. The failure
indication remains on for as long as the
sensor is active.
The rain sensor is able to recognize and
automatically adjust itself in the
presence of the following conditions:
Presence of dirt on the controlled
surface (e.g. salt, dirt, etc.).
Presence of streaks of water caused
by the worn window wiper blades.
Difference between day and night.

always off with intake of outside air):
both indicators not illuminated on the Air
Recirculation Button
The three operating conditions are
obtained by pushing the Air Recirculation
Button
in sequence. Enabling The Air Quality System (AQS)
Function — If Equipped
When the automatic recirculation
function is selected, the AQS function
automatically activates internal air
recirculation when the outside air is
polluted (e.g. in heavy traffic and tunnels).
At low external temperatures or in high
humidity, the automatic function turns
off to avoid fogging up the windows.
The user can select the function again by
pushing the Air Recirculation Button.
In
automatic operation, air recirculation
will be controlled by the system according
to outside environmental conditions.
Note:
With the AQS function active and
after the internal air recirculation
system has been functioning for a set
amount of time, the Climate Control
System enables air intake to cycle the
air in the passenger compartment for a
set time. The AQS function is disabled
during the air changes.
The engagement of the recirculation
system makes it possible to reach the
required heating or cooling conditions
faster. It is, however, inadvisable to use
it on rainy/cold days as it can increase
the possibility of the windows fogging.
When the outside temperature is low,
recirculation is forced off to prevent the
windows from fogging up.

A/C Compressor
Push the A/C button to activate or
deactivate the A/C compressor (indicator
illuminated when activated). The A/C
compressor will remain off even after the
engine has stopped.
When the A/C compressor is turned off,
the system deactivates air recirculation
to prevent the windows from fogging up.
If the climate control system can
maintain the temperature, with the A/C
turned off, the AUTO feature will remain
on and the AUTO button indicator light
will not switch off.
To restore automatic control of the A/C
compressor, push the A/C button or the
AUTO button. With the A/C compressor
off, the air speed can be set manually
using the Air Speed Adjustment Knob.
When the A/C compressor is on, and the
engine is running, air speed cannot be
lower than the minimum speed (only one
indicator light is lit).
Note:
When the A/C is off the Climate
Control system can not produce air that
is colder than the current outside
temperature. Under certain environmental
conditions, windows could fog up rapidly,
since the air is not dehumidified.
Front Defroster And MAX-DEF
Function
Push the Front Defroster button(indicator illuminated) to defrost the
windshield and side windows.
While in MAX-DEF function, the air
conditioner will:
Activate the air conditioner

GETTING TO KNOW YOUR VEHICLE

Note:The climate control system stores
the previously set temperatures and
resumes operation when any button on
the system is pushed.
Switching On The Climate Control
System
To switch the climate control system on
in automatic mode, push the AUTO
button.
Stop/Start
The climate control system manages the
Stop/Start system. Stop/Start has the
engine shut off when vehicle speed is
0 mph (0 km/h) to maintain comfort
within the vehicle.
Stop/Start will deactivate in the
following scenarios:
The climate control system is in AUTO
mode (indicator illuminated), and the
vehicle has yet to reach the set
temperature
The climate control system is in LO
maximum cooling
The climate control system is in HI
maximum heating
The climate control system is in the
MAX-DEF status
When the Stop/Start system is active,
the engine will restart if the inside
temperature changes significantly, or if
the LO setting, or MAX-DEF setting, is
activated. With Stop/Start system on, air flow is
reduced to keep the compartment
comfort conditions for longer.
Until the temperature drastically
changes within the cabin, the climate
control system will continue to maintain
the temperature while the engine is off.
By deactivating the Stop/Start system
with the
button located on the
dashboard, the climate control system
will take priority over the engine shutting
off.
Note:
In harsh climate conditions, limit the
use of the Stop/Start system to prevent
the compressor from continuously
switching on and off. This will cause
rapid misting of the windows and the
accumulation of humidity in the
passenger compartment.
When the Stop/Start system is on,
the climate control system will always
take air in from outside, reducing the
probability of the windows fogging up.
System Maintenance
In winter, the Climate Control System
must be turned on at least once a month
for approximately ten minutes.
Have the system inspected at an
authorized dealer before the summer.

ANTI-LOCK BRAKE (ABS) INDICATOR LIGHT
This light monitors the Anti-Lock Brake System (ABS). The
light will turn on when the ignition is placed in the ON/RUN
position and may stay on for as long as four seconds.
If the ABS light remains on or turns on while driving, then the
Anti-Lock portion of the brake system is not functioning and
service is required. However, the conventional brake system
will continue to operate normally if the brake indicator light
is not on.
If the ABS light is on, the brake system should be serviced as
soon as possible to restore the benefits of Anti-Lock
Brakes. If the ABS light does not turn on when the ignition is
placed in the ON/RUN position, have the light inspected by
an authorized dealer.Drive carefully and contact an authorized dealer as soon as
possible.
TIRE PRESSURE MONITORING INDICATOR LIGHT
The warning light switches on and a message is displayed to
indicate that the tire pressure is lower than the
recommended value and/or that slow pressure loss is
occurring. In these cases, optimal tire duration and fuel
consumption may not be guaranteed.
Should one or more tires be in the condition mentioned
above, the display will show the indications corresponding
to each tire in sequence.
Continue driving for up to 50 miles (80 km) at a speed no
higher then 50 mph (80 km/h). Contact an authorized dealer
to have the tire repaired.

ONBOARD DIAGNOSTIC
SYSTEM
Operation
The OBD (Onboard Diagnostic system)
carries out a continuous diagnosis of the
components of the vehicle related to
emissions.
It also alerts the driver of when these
components are no longer in peak
condition by switching on the
warning
light on the instrument panel (see
“Warning Lights And Messages”
paragraph in this chapter).
The aim of the OBD system (Onboard
Diagnostic) is to:
Monitor the efficiency of the system
Indicate an increase in emissions
Indicate the need to replace damaged
components
The vehicle also has a connector, which
can interface with appropriate tools, that
makes it possible to read the error codes
stored in the electronic control units
together with a series of specific
parameters for engine operation and
diagnosis. This check can be carried out
by your authorized dealer.
Note: After eliminating a fault, to check
the system completely, your authorized
dealer is obliged to run tests and, if
necessary certain road tests.
Onboard Diagnostic System (OBD II)
Cybersecurity
Your vehicle is required to have an
Onboard Diagnostic system (OBD II) and
a connection port to allow access to
information related to the performance
of your emissions controls. Authorized
service technicians may need to access
this information to assist with the
diagnosis and service of your vehicle and
emissions system.
Warning!
ONLY an authorized service technician
should connect equipment to the OBD II
connection port in order to read the VIN,
diagnose, or service your vehicle.
If unauthorized equipment is connected to
the OBD II connection port, such as a
driver-behavior tracking device, it may:
Be possible that vehicle systems,
including safety related systems, could be
impaired or a loss of vehicle control could
occur that may result in an accident
involving serious injury or death.
Access, or allow others to access,
information stored in your vehicle systems,
including personal information.
EMISSIONS INSPECTION AND
MAINTENANCE PROGRAMS
In some localities, it may be a legal
requirement to pass an inspection of your
vehicle's emissions control system.
Failure to pass could prevent vehicle
registration.
For states that require
an Inspection and
Maintenance (I/M), this
check verifies the
“Malfunction Indicator
Light (MIL)” is functioning and is not on
when the engine is running, and that the
OBD II system is ready for testing.
Normally, the OBD II system will be ready.
The OBD II system may notbe ready if
your vehicle was recently serviced,
recently had a dead battery or a battery
replacement. If the OBD II system should
be determined not ready for the I/M test,
your vehicle may fail the test.
Your vehicle has a simple ignition
actuated test, which you can use prior to
going to the test station. To check if your
vehicle's OBD II system is ready, you
must do the following:
1. Cycle the ignition switch to the ON
position, but do not crank or start the
engine.
Note: If you crank or start the engine,
you will have to start this test over.

GETTING TO KNOW YOUR INSTRUMENT PANEL

Operating Example
For example, your vehicle may have a
recommended cold (parked for more than
three hours) placard pressure of 33 psi
(227 kPa). If the ambient temperature is
68°F (20°C), and the measured tire
pressure is 28 psi (193 kPa), a
temperature drop to 20°F (-7°C) will
decrease the tire pressure to
approximately 24 psi (165 kPa). This tire
pressure is low enough to turn on the
“Tire Pressure Monitoring Warning Light.”
Driving the vehicle may cause the tire
pressure to rise to approximately 28 psi
(193 kPa), but the “Tire Pressure
Monitoring Telltale Light” will still be on.
In this situation, the “Tire Pressure
Monitoring Warning Light” will turn off
only after the tires are inflated to the
vehicle’s recommended cold placard
pressure value.
Caution!
The TPMS has been optimized for the
original equipment tires and wheels.
TPMS pressures and warning have been
established for the tire size equipped on
your vehicle. Undesirable system operation
or sensor damage may result when using
replacement equipment that is not of the
same size, type, and/or style. The TPM
sensor is not designed for use on
aftermarket wheels and may contribute to a
poor overall system performance or sensor damage. Customers are encouraged to use
OEM wheels to assure proper TPM feature
operation.
Using aftermarket tire sealants may
cause the Tire Pressure Monitoring System
(TPMS) sensor to become inoperable.
After using an aftermarket tire sealant it is
recommended that you take your vehicle to
your authorized dealer to have your sensor
function checked.
After inspecting or adjusting the tire
pressure always reinstall the valve stem
cap. This will prevent moisture and dirt from
entering the valve stem, which could
damage the TPMS sensor.
Insufficient Tire Pressure Indication
If an insufficient pressure value is
detected on one or more tires, the
warning light in the instrument cluster
will display alongside the dedicated
messages, the system will highlight the
tire or tires with insufficient pressure
graphically, and an acoustic signal will be
emitted.
In this case, stop the vehicle, check the
inflation pressure of each tire, and inflate
the necessary tire or tires to the correct
cold inflation pressure value, shown on
the display or in the dedicated TPMS
menu. TPMS Temporarily Disabled — TPMS
Check Message
When a system fault is detected, the “Tire
Pressure Monitoring Telltale Light” will
flash on and off for 75 seconds, and then
remain on solid. The system fault will also
sound a chime. If the ignition is cycled,
this sequence will repeat, provided that
the system fault still exists. The “Tire
Pressure Monitoring Telltale Light” will
turn off when the fault condition no
longer exists. A system fault can occur
due to any of the following:
Jamming due to electronic devices or
driving next to facilities emitting the
same radio frequencies as the TPMS
sensors.
Installing some form of aftermarket
window tinting that affects radio wave
signals.
Accumulation of snow or ice around
the wheels or wheel housings.
Using tire chains on the vehicle.
Using wheels/tires not equipped with
TPMS sensors.
After the punctured tire has been
repaired with the original tire sealant
contained in the Tire Repair Kit, the
previous condition must be restored so
that the
warning light is off during
normal driving.
