air condition MASERATI QUATTROPORTE 2019 Service Manual

When the tread is worn to one of the
tread wear indicators, the tire should
be replaced.
WARNING!
The wet performance (aquaplaning
resistance) will decrease
proportionally to the thickness of the
tread.
Tires Durability The service life of a tire depends on
various factors including, but not
limited to:
• driving style;
• tire pressure;
• distance driven.
WARNING!
Tires and the spare tire (if equipped)
should be replaced after six years,
regardless of the remaining tread.
Failure to follow this warning could
result in tire failure. Replacement Tires NOTE:
In order to maintain high performance
and safety level under all driving
conditions, Maserati strongly
recommends to use tires equivalent to
the originals in size, quality and
performance when replacement is
needed.
For the size designation of your tire
see the label on the driver's side rear
door pillar or see table “Wheels” in
section “Features and Specifications”.
The “Load Index” and “Speed Symbol”
for your tire will be found on the
original equipment tire sidewall.
NOTE:
Maserati recommends Maserati
Genuine Tires marked with “MGT”
logo specifically designed for its
models.
It is recommended to replace the two
front tires or two rear tires as a pair.
Replacing just one tire can seriously
affect your vehicle’s handling.
If you ever replace a wheel assembly,
make sure that the wheel’s
specifications (valve, TPMS sensor and
tire) match those of the original
wheels. Failure to use equivalent replacement tires may adversely affect
the safety, handling, and ride of your
vehicle.
Your Authorized Maserati Dealer is
available to provide suggestions as to
the types of tires most suited to the
use foreseen by the Customer.
WARNING!
• Do not use a tire, wheel size or
rating other than that specified for
your vehicle. Some combinations of
unapproved tires and wheels may
change suspension dimensions and
performance characteristics,
resulting in altered steering,
handling, and braking operations of
the vehicle. This can cause
unpredictable handling and stress to
steering and suspension
components. Use only the tire and
wheel sizes with load ratings
appointed for your vehicle.
• Never use a tire with a smaller load
index or capacity, other than what
was originally equipped on your
vehicle. Using a tire with a smaller
load index could result in tire
overloading and failure.
• Always check the maximum speed
rating on the tire sidewall on anyDriving

Compact Spare Tire The limited-use spare tire, or compact
spare tire, is for temporary emergency
use only.
This tire is identified by a label
indicating the driving speed limitations
to comply with when using the spare
tire.
Inflate the spare tire to the cold
inflation pressure listed on the table
“Tire Inflation Pressure” in section
“Features and Specifications”.
Mounting the spare tire affects vehicle
handling. Replace (or repair) as soon as
possible the original equipment tire
and reinstall it on the vehicle. Do not
install more than one compact spare
tire and wheel on the vehicle at a
time.
WARNING!
With these compact spare tires, do not
drive more than 50 mph (80 km/h).
Temporary use spares have limited
tread life. Tire Pressure Monitoring
System (TPMS) The Tire Pressure Monitoring System
(TPMS) will warn the driver of a low
tire pressure according to the vehicle
recommended cold pressure indicated
on the table “Tire Inflation Pressure”
in section “Features and
Specifications” and on the label
applied on the driver's side rear door
pillar.
Tire pressure should always be set
based on cold inflation tire pressure.
The cold tire inflation pressure must
not exceed the maximum inflation
pressure molded into the tire sidewall.
Check “Tires – General Information” in
section “Driving” for information on
how to properly inflate the tires.
The tire pressure will also increase as
the vehicle is driven - this is normal
and there is no adjustment required
when this occurs.
The TPMS will warn the driver of a low
tire pressure if the tire pressure falls
below the low-pressure warning limit
for any reason, including low
temperature effects and natural
pressure loss of the tire.
The TPMS will continue to warn the
driver of low tire pressure as long as
the condition persists and will not turn off until the tire pressure is equal or
above the recommended cold inflation
pressure. Once the low tire pressure
warning light
illuminates, you must
increase the tire pressure to the
recommended cold inflation pressure
in order for the TPMS light
to turn
off. The system will automatically
update and the TPMS light
will turn
off once the system acquires the
correct tire pressure.
The vehicle may need to be driven for
up to 20 minutes above 15 mph
(24 km/h) in order for the TPMS to
acquire and process the updated
setting.Driving

Materials Added to Fuel All gasoline sold in the United States is
required to contain effective
detergent additives. Use of additional
detergents or other additives is not
needed under normal conditions and
they would result in additional cost.
Therefore, you should not have to add
anything to the fuel.
Fuel System Warnings WARNING!
Follow these guidelines to maintain
your vehicle's performance:
• The use of leaded gasoline is
prohibited by Federal and Provincial
law. Using leaded gasoline can
impair engine performance and
damage the emissions control
system.
• The use of fuel additives, which are
now being sold as octane enhancers,
is not recommended. Most of these
products contain high concentrations
of methanol. Fuel system damage or
vehicle performance problems
resulting from the use of such fuels
or additives is not the responsibility
of Maserati. NOTE:
Intentional
tampering with the
emissions control system can result in
civil penalties civil penalties and could
void the vehicle warranty.
Carbon Monoxide Warnings WARNING!
Carbon monoxide (CO) in exhaust
gases is deadly. Follow the precautions
below to prevent carbon monoxide
poisoning:
• Do not inhale exhaust gases. They
contain carbon monoxide, a colorless
and odorless gas, which can kill.
Never run the engine in a closed
area, such as a garage, and never sit
in a parked vehicle with the engine
running for an extended period. If
the vehicle is stopped in an open
area with the engine running for
more than a short period, adjust the
ventilation system to force fresh,
outside air into the vehicle.
• Guard against carbon monoxide
with proper maintenance. Have the
exhaust system inspected every time
the vehicle is raised. Have any
abnormal conditions repaired promptly. Until repaired, drive with
all side windows fully open.
WARNING!
California Proposition 65
Operating, servicing and maintaining
a passenger vehicle or off-road vehicle
can expose you to chemicals including
such as, engine exhaust, carbon
monoxide, phthalates and lead, that
which are known to the State of
California to cause cancer and birth
defects or other reproductive harm. To
minimize exposure, avoid breathing
exhaust, do not idle the engine except
as necessary, service your vehicle in a

Some advices for driving in the rain are
listed below.
• Reduce your speed and keep a
greater safety distance from the
vehicles in front of you. High speed
may result in a loss of vehicle control.
• When driving on wet or slushy roads,
it is possible for a wedge of water to
build up between the tire and road
surface. This is known as
aquaplaning and may cause partial
or complete loss of vehicle control
and stopping ability. To reduce this
possibility: slow down if the road has
standing water or puddles.
• Heavy rain substantially reduces
visibility. In these circumstances, even
during the day, turn on the low
beams, to be more visible to other
drivers.
• Set the air conditioning and heating
system controls on the defogging
function, in order to avoid any
visibility problem.
• Periodically check the conditions of
the windshield wiper blades.
• In low grip conditions use “I.C.E.”
driving mode (see chapters “Drive
Mode” in this section). • Avoid driving with ESC OFF as this
will likely cause a loss of control of
the vehicle.
Driving in Fog
If the fog is dense, avoid traveling if
possible.
When driving in mist, blanket fog or
when there is the possibility of banks
of fog, please consider some advices
listed below.
• Keep a moderate speed.
• Even in daytime, turn on the low
beams and rear fog lights. Do not
use the high beams.
• Remember that fog creates
dampness on the asphalt and thus
any type of maneuver is more
difficult and braking distances are
extended.
• Keep a safe distance from the vehicle
in front of you.
• Avoid sudden changes in speed as
much as possible.
• Whenever possible, avoid overtaking.
• If you are forced to stop the vehicle
(breakdowns, impossibility of
proceeding due to poor visibility,
etc.), first of all, try to stop off of the
travel lane. Then turn on the hazard
warning flashers and, if possible, the
low beams. CAUTION!
Be aware that rear fog lights can
bother the drivers following your
vehicle: when visibility is back to
normal, turn off these lights.
Driving in the Mountains
Mountain
roads usually
have many
narrow turns and curves, tunnels and
steep uphill or downhill slopes: please
consider some advices listed below.
• Drive at a moderate speed, avoid
“cutting” corners.
• When driving inside a tunnel in
daylight turn on the low beams in
advance; avoid high beams and be
aware of the rapid brightness
change. Avoid abrupt maneuvers
that could be dangerous for the
following vehicle.
• Never coast downhill with the engine
off or in neutral.
• Remember that passing other
vehicles when driving uphill is slower
and thus requires more free distance
on the road. If you are being
overtaken on a hill, slow down and
allow the other vehicle to pass.Driving

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.
