spare wheel MASERATI QUATTROPORTE 2019 Owners 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

Vehicles with Compact Spare Tire
• The compact spare tire does not
have a TPMS sensor. Therefore, the
TPMS will not monitor the pressure
of the compact spare tire.
• If you replace a tire having pressure
below the low-pressure warning
limit, with the compact spare tire, on
the next ignition switch cycle, the
TPMS light
will illuminate
followed by a beeping sound. In addition, the graphic in the
instrument cluster will still display a
flashing pressure value
corresponding to the compact tire
position.
• After driving the vehicle for up to 20
minutes above 15 mph (24 km/h),
the TPMS light
will flash for 75
seconds and then remain lit. The
instrument cluster will then display a
"Service Tire Pressure System"
message for a minimum of five
seconds and then display dashes (--)
in place of the pressure value.
• Each subsequent ignition switch
cycle will be followed by a beeping
sound, the TPMS light
will flash
for 75 seconds and then remain lit.
The instrument cluster will then
display a "Service Tire Pressure
System" message for a minimum of
five seconds and subsequently displays dashes (--) in place of the
pressure value.
• Once you repair, replace or reinstall
a tire with the compact spare tire,
the TPMS will update automatically.
The TPMS light
will turn OFF and
the graphic in the instrument cluster
will display a new pressure value
instead of dashes (--), as long as no
tire pressure is below the
low-pressure warning limit in any of
the four tires. 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 information.
TPMS Deactivation The TPMS can be deactivated if
replacing all four tire rims with wheel
and tire assemblies not using of TPMS
sensors, such as winter wheel and tireDriving

Using the Compact Spare
Wheel NOTE:
The compact spare wheel is supplied in
aluminium or steel: the pictures show
the one in aluminium.
The compact spare wheel is stored in
the trunk and is supplied deflated in
order to limit the amount of space
occupied. An electric compressor is also
provided for inflating. In the event of
a tire puncture, proceed as follows.
• Stop the vehicle in a place that does
not constitute a danger to traffic and
where the wheel can be changed
safely.
• Select the P (Park) mode and then
engage manually the electric parking
brake and move the ignition switch
to OFF position.
• If necessary, turn the hazard warning
flashers on and place the warning
triangle (if equipped) at the required
distance.In an Emergency

• If provided, the chock can be
installed in order to improve vehicle
stability.
WARNING!
The vehicle must be level and on the
firm ground during the vehicle lifting
operations. If forced to stop the
vehicle on a slope, call the Assistance
service and avoid any operation.
• Before placing the chock, it is
necessary
to open
it like a book as
shown in the picture. • Lift the ground coverage of the
trunk.
• Take the tools for changing the
wheel (indicated in picture) from the
container.
• Unscrew and pull out the locking
wheel knob. • Take the container and the compact
spare wheel out of the trunk.
• Remove from the compressor case
the inflation hose and the cable with
a plug for the power outlet.
• Unscrew the valve cap of the
compact spare wheel and screw the
fitting of the inflation hose onto the
valve.
• Insert the power plug into one of
the available power outlets fitted in
the trunk or passenger
compartment.
• Set the ignition device on ACC or
RUN position.
• Turn the compressor on by pressing
the switch.
• Stop the compressor by pressing the
switch again, when the pressure
indicated by the gauge reaches the
recommended level (see “TireIn an Emergency

Inflation Pressure” in section
“Features and Specifications”) and
screw the cap on the compact spare
wheel valve.
CAUTION!
• In order to obtain a more accurate
reading, the compressor should be
switched off when checking the tire
pressure of the compact spare wheel
on the pressure gauge.
• Do not run the compressor for more
than 20 minutes: there is a risk it
could overheat. Also, prolonged
power absorption may discharge the
battery, subsequently preventing the
engine from starting.
• The compressor has been designed
exclusively to inflate compact spare wheels; do not use it to inflate air
mattresses, floatation devices, etc.
• Fit the adapter on the wrench.
Extend
the wrench as shown, then
loosen by approximately one turn,
the five bolts on the wheel to be
changed.
• Place the jack near the wheel to be
changed as illustrated.
• Make sure that the head of the jack
is correctly inserted in one of the
slots beneath the rocker panel.
WARNING!
• The jack should be used on level firm
ground wherever possible.
• It is recommended that the wheels
of the vehicle be chocked, and that
no person should remain in a vehicle that is being jacked.
• If the vehicle has been stopped on a
slope or an uneven surface, place
chocks or other suitable items in
front of or behind the wheels to
stop the vehicle from moving.
• Never start or run the engine with
the vehicle on a jack.
• No person should place any portion
of their body under a vehicle that is
supported by a jack.
WARNING!
• Never position yourself under a
jacked vehicle.
• The lifted vehicle may fall and
damage the vehicle's body if the jack
is not positioned correctly.
• Never use the jack to carry out
maintenance or repairs under the
vehicle.
• Turn the jack lever until the wheel is
raised a few
centimeters off the
ground.
• Completely unscrew the five bolts
and remove the wheel. In case a
wheel security stud bolt is installed, it
can only be removed by using theIn an Emergency

WARNING!
• The spare wheel is narrower than
standard wheels and must only be
used to travel the distance required
to reach a service station, where the
punctured tire can be repaired or
replaced.
• Do not exceed a maximum speed of
50 mph (80 km/h) when using the
compact spare wheel; when this
limit is exceeded, the stability, road
holding and braking of the vehicle
will be compromised. Avoid
accelerating to full speed, heavy
braking and fast cornering.
• The compact spare wheel must be
inflated to the recommended tire
pressure (see “Tire Inflation
Pressure” in section “Features and
Specifications”). • For safety reasons, it is absolutely
forbidden to drive with more than
one compact spare wheel fitted on
the vehicle.
• Snow chains cannot be fitted on the
compact spare wheel.
• The spare wheel can travel a
maximum of 1,800 mi (3.000 km).
To Refit the Standard Wheel with
Repair
ed or
Replaced Tire
• Following the procedure and the
caution described above, raise the
vehicle and remove the compact
spare wheel reusing the supplied
wrench with adapter, suitably
extended.
• Fit the standard wheel with repaired
or replaced tire.
• Tighten the original bolts on the
wheel.
• Lower the vehicle and remove the
jack.
• Fully tighten the bolts, alternately
tightening diametrically opposite. WARNING!
Observe the tightening torque for the
bolts securing the wheels (72 ± 7 lbf·ft
/ 98 ± 10 Nm). Check the correct
tightening torque as soon possible
contacting an Authorized Maserati
Dealer.
Once finished:
•
completely deflate
the compact

• wrap the power cable and the
inflation hose inside the compressor
case.
• place the compressor, the jack, the
wrench and the adapter in the
container inside the compact spare
wheel;
• reposition the other tools;
• lower the ground coverage at the
bottom of the trunk. Emergency Release of the
Parking Brake In the event the electric parking brake
locks due to a system failure (see
“Parking Brake” in section “Driving”),
it is not possible to move the vehicle,
since the actuator that operates on
the brake pad inside each rear caliper
will lock the rear wheels.
After verifying that the battery is
sufficiently charged (otherwise use an
external power source connected to
the vehicle electric system to operate
the EPB control lever and try to unlock
the parking brake), for moving the
vehicle it is necessary to force the
actuator to release the rear brake
discs. Contact the Authorized Maserati
Dealer to carry out this operation.
WARNING!
If the parking brake has been
activated in manual or automatic
mode and it is not possible to release
it by operating on the lever of the
central console, do not move the
vehicle since rear brake calipers might
be damaged. For more information on vehicle towing see "Towing a Disabled
Vehicle" chapter in this section.
