2019 MASERATI QUATTROPORTE air filter

relevant soft-key button to activate
the two different functionalities.
The recirculation function, that allows
to open/close the A/C air inlet by
operating the
button on the
climate control panel or the MTC+ soft
key, is integrated with the Air Quality
Sensor.
This sensor, positioned upstream of the
A/C filter, in front of the air intake of
the A/C system, detects the presence of
polluting substances and submits an
electric signal to the A/C control unit,
that closes the intake of the external
air by activating the air recirculation.
The
button or the MTC+ soft-key
can therefore enable three operating
modes, switchable in sequence.
Starting from the outside air condition
with LED on the button off and MTC+
soft-key not highlighted, in which the
external air is aspirated by the A/C
system and treated to be introduced
into the passenger compartment,
subsequent actuations of the
button or the MTC+ soft-key
change the state as follows.
• First press: the A/C system activates
the automatic recirculation control
by using the signal transmitted from
the AQS. The symbol “A” on the
button and the MTC+ soft-key
lights up. • Second press: the A/C system
activates the recirculation, the LED
on the button or the MTC+ soft-key
light up. The A/C system will stay this
way up to a new actuation, or until
the increased humidity could lead to
windshield fogging: in this case the
recirculation automatically switches
to external air.
• Third press: the A/C system switches
back to external air (default
operating mode).
The next press of the
button or
the MTC+ soft-key restarts the
operating cycle just described.
NOTE:
To avoid the risk of fogging, the AQS is
disabled when the external
temperature falls below 35 °F (2 °C). NOTE:
In cold weather, use of recirculation
mode may lead to window fogging.
Select the MIX mode and increase
the blower speed to prevent fogging.
MAX A/C
Activating this function, the system
switches to exit “AUTO”, enter “A/C”
and recirculation. The minimum
temperature (LO) in both zones, the
maximum blower speed and the
“Dashboard” air distribution mode
are also selected.
The blower speed can be adjusted and
the air distribution can be modified
without exiting “MAX A/C”. To exit
“MAX A/C” touch the relevant MTC+
soft-key or exit A/C or recirculation.Dashboard Instruments and Controls

the air conditioning system at idle
for about five minutes in the fresh
air by high blower setting. This will
ensure adequate system lubrication
and minimize the possibility of
compressor damage when the
system is started again.
A/C Filter The climate control system filters
outside air containing dust, pollen and
some odors. Strong odors cannot be
totally removed by A/C filter at the
entrance of the air climate system. See
“Maintenance Procedures” in section
“Maintenance and Care” for filter
replacement instructions. Phone and Voice Controls
on Steering Wheel The commands on the right side of the
steering wheel activate/deactivate the
phone mode (
) and the Voice
Recognition (
) controls functions.
These functions are only available
when one or more Bluetooth ®
compatible mobile phones are paired
with the MTC+ System connection: to
pair a phone and to learn all available
functions refer to the MTC+ guide.
NOTE:
On the Maserati website, at
www.maserati.com , or through an
Authorized Maserati Dealer you may
consult the list of telephones that are
compatible with the MTC+, and their
level of compatibility. The voice command communication
system is fully integrated with the
vehicle's audio system.
The volume can be adjusted from the
upper knob on the central console
(see “Infotainment System” in this
section or from the steering wheel
radio controls (see “Audio Controls” in
this section).
The system will automatically mute
the radio when using the phone
mode.
When activating the phone mode
using voice commands with
speakerphone, you should talk quietly
in a normal conversational tone by
keeping the driving position and
turning to the microphone of the
voice command system located inside
of the internal rear-view mirror.
The ability of the system voice control
to recognize the user's voice
commands can be invalidated when
speaking too quickly or too loudly.Dashboard Instruments and Controls

• short, repeated journeys (less than
4–5 mi/7-8 km) at sub-zero outside
temperatures;
• engine often idling or driving long
distances at low speeds or long
periods of idleness;
you should perform the following
inspections more frequently than
recommended on the “Scheduled
Service Plan”:
• check front disc brake pad conditions
and wear;
• check cleanliness of hood and trunk
locks, cleanliness and lubrication of
linkage;
• visually inspect conditions of: engine,
transmission, pipes and hoses
(exhaust - fuel system - brakes) and
rubber elements (boots - sleeves -
bushes - etc.);
• check battery charge;
• visually inspect condition of the
accessory drive belts;
• check and, if necessary, change
engine oil and replace oil filter;
• check and, if necessary, replace
pollen filter of the A/C system;
• check and, if necessary, replace air
cleaner filter. CAUTION!
All maintenance operations for the
vehicle must be carried out by an
Authorized Maserati Dealer . For
routine and minor maintenance
operations which you can carry out
yourself, make sure that you have the
necessary experience and always use
suitable equipment, original Maserati
spare parts and the prescribed fluids.
Shall this not be the case, do not carry
any operation on your own and
contact an Authorized Maserati
Dealer .
On Board Diagnostic System Your vehicle is equipped with a
sophisticated on board diagnostic
system called OBD II. This system
monitors the performance of the
emissions, engine, and automatic
transmission control systems. When
these systems are operating properly,
your vehicle will provide excellent
performance and fuel economy, as
well as engine emissions suited to
current government regulations.
If any of these systems require service,
the OBD II system will turn on the
Malfunction Indicator Light
on the
instrument cluster display (refer to “Instrument Cluster” in section
“Dashboard Instruments and
Controls”). The system stores as well
diagnostic codes and other
information to assist your service
technician by performing repairs.
Although the vehicle will be driveable
and will not need towing, contact an
Authorized Maserati Dealer for service
as soon as possible.
CAUTION!
• Prolonged driving with the MIL
on could cause further damage to
the emissions control system. It could
also affect fuel economy and
driveability. The vehicle must be
serviced before any emissions tests
can be performed.
• If the MIL
is flashing while the
engine is running, severe catalytic
converter damage and power loss
will soon occur. Immediate service at
an Authorized Maserati Dealer is
required.
Emissions Inspection and
Maintenance Programs In some localities, it may be a legal
requirement to pass an inspection of

Engine Air Filters Replacement Contact an Authorized Maserati
Dealer to have the air filters replaced.
A/C Air Filter Replacement This filter performs mechanic/
electrostatic air filtering, provided that
windows and doors are closed.
The filter is located under the hood in
the external A/C system air inlet, on
the passenger side of the vehicle, next
to the windshield wipers.
To replace the filter during the
scheduled maintenance services or
after the vehicle has been heavily used
on dusty roads, proceed as follows:
• Remove the access door in the cowl
screen by pressing the retaining clips
indicated. • Unsnap both ends and lift the filter
retaining cover.
• Remove the used filter slipping it off
from within the air intake.
• Install the new filter with arrows
pointing in the direction of airflow,
which is toward the rear of the
vehicle (text and arrows on the filter
will indicate this). • Close the filter retaining cover and
reinstall the access door.
CAUTION!
Failure to replace the filter may
considerably reduce the air
conditioning and heating system
efficiency.
Wiper Maintenance and Blades
Replacement Windshield Wiper Arms Lifting
When the windshield wiper arms are
in rest position it is not possible to
check or replace the blades as they

• Cover the vehicle with a long cloth
in breathable fabric (available from
an Authorized Maserati Dealer ). Do
not use thick plastic sheets, which do
not allow the humidity on the
vehicle surface to evaporate.
• Inflate the tires up to a pressure
which must be 14.5 psi (1 bar) higher
than the normally prescribed one,
and check it at regular intervals.
NOTE:
The Authorized Maserati Dealer can
provide you with any information
about the available “Indoor and
Outdoor Car Covers”, available in the
“Genuine Accessories” range.
WARNING!
The tire pressure must be brought
back to the prescribed value before
reusing the vehicle (see “Tire Inflation
Pressure” in section “Features and
Specifications”). Restarting the Vehicle Before restarting the vehicle after a
long period of inactivity, we
recommend that you carry out the
following operations.
• Check the tires for pressure and for
any damages, cuts or cracks. If this is
the case, have them replaced.
• Do not dry-rub the external surface
of the vehicle: use a damp cloth.
• Visually inspect if there are any fluid
leaks (oil, brake and clutch fluid,
engine coolant etc.).
• Have the engine oil and filter
replaced.
• Check the fluid levels in the brake
system, as well as the engine coolant
level.
• Check the air filters and have them
replaced if necessary.
• Reconnect the battery after checking
the charge status (refer to
“Maintenance-Free Battery” in this
section) and perform the initializing
procedure if applicable. You can
consult the paragraph “Battery
Reconnection” in this chapter for
further information on this subject. • With the transmission in N (Neutral),
let the engine idle for several
minutes.
