the speed stored. Every time rotating
section is reset, the speed is increased
or decrease by approx. 0.6 mph (1
Km/h). Keep the rotating section
turned to vary the speed
continuously. When a new speed is
reached, it will automatically remain
constant.
• Button "RCL" at end of left
multifunction lever is used to resume
the speed stored.
NOTE:
•When the key in the ignition switch
is turned toSTOP (OFF)position or
ON/OFF switch is in the "OFF"
position, the speed stored is erased
and the system deactivated.
•The CC must be deactivated when
not in use.
WARNING!
Leaving the Cruise Control system on
when not in use is dangerous. You
could accidentally set the system or
cause it to go faster than you want.
Always leave the CC off when you are
not using it.
Storing a Speed
Turn the ON/OFF switch to "ON" and
reach the desired speed driving
normally. Turn the rotating section in
the middle of the left multifunction
lever to "+" for at least 3 seconds and
then release it.
The vehicle speed is stored and the
accelerator pedal can be released.
The vehicle will proceed at the
constant speed stored until the brake
pedal is pressed.
If necessary, (for example, to pass
another vehicle), you can accelerate by
simply pressing the accelerator pedal.
Afterward, when you release the
accelerator pedal, the vehicle will
return to the speed previously stored.
Resuming the Speed Stored
If the CC has been deactivated after
braking, the speed previously stored
can be resumed as follows:
• gradually accelerate until you reach a
speed close to that stored;
• engage the gear selected when the
speed was stored (4th, 5th or 6th
gear);
• press button "RCL".
Increasing the Speed Stored
The speed stored can be increased in
two ways:• by pressing the accelerator and then
storing the new speed reached (turn
the rotating section in the middle of
the left multifunction lever for more
than 3 seconds); or
• by turning the rotating section to
position "+": each impulse
transmitted by the rotating section
will cause a slight increase in speed
(about 0.6 mph/1 Km/h), whereas a
constant pressure on the same
rotating section will cause a
continuous increase in speed. When
the rotating section is released, the
new speed will be automatically
stored in the memory.
Decreasing the Speed Stored
The speed stored can be reduced in
two ways:
• by deactivating the CC, pressing the
brake pedal and then storing the
new speed (turning the rotating
section to position “+” for at least 3
seconds); or
• by keeping the rotating section
turned to position “-” until reaching
the new speed, which will be stored
automatically.
Resetting the Speed Stored
The speed stored is automatically
reset:

advisable to activate CC only when
traffic and road conditions permit
safe use of this device, that is: on
straight and dry roads, expressways
or highways, smooth flowing traffic
and smooth asphalt. Do not activate
this device when driving in town or
in heavy traffic.
•CC can only be activated at speeds
exceeding 19 mph (30 km/h).
•CC can only be activated in 4th, 5th
or 6th gear, depending upon the
vehicle speed.
•When driving downhill with the CC
activated, the vehicle may pick up
speed slightly exceeding the speed
stored, due to the change in the
engine load.
•In the event of malfunctioning or
failure of CC, turn ON/OFF switch to
"OFF" position and contact the
Authorized Maserati Dealer afterhaving checked that the relative
fuse is in proper working order.
•ON/OFF switch can be always left at
"ON" position without damaging
the CC. In any case, it is advisable to
deactivate the CC when it is not in
use. Turn ON/OFF switch to "OFF"
position to prevent any speeds from
being unintentionally stored.

Tire and Loading Information Label
The proper cold tire inflation pressure
is listed on the driver's side rear door
pillar.
This label tells you important
information about the:
• Number of people that can be
carried in the vehicle.
• Total weight the vehicle can carry.
• Tire size designed for the vehicle.
• Cold tire inflation pressures for the
front, rear, and spare tires.
Loading
The vehicle maximum load on the tire
must not exceed the load carrying
capacity of the tire on your vehicle.
You will not exceed the tire's load
carrying capacity if you adhere to the
loading conditions, tire size, and cold
tire inflation pressures specified onthe “Tire and Loading Information
Label” and in the “Features and
Specifications” section.
NOTE:
Under a maximum loaded vehicle
condition, gross axle weight ratings
(GAWRs) for the front and rear axles
must not be exceeded.
Tires
Driving over rough or damaged road
surfaces, as well as debris, curbs and
other obstacles can cause serious
damage to wheels, tires, and
suspension parts.
This is more likely to occur with
low-profile tires, which provide less
cushioning between the wheel and
the road.
Be careful to avoid road hazards and
reduce your speed, especially if your
vehicle is equipped with low profile
tires.
WARNING!
Overloading of your tires is
dangerous. Overloading can cause tire
failure, affect vehicle handling, and
increase the stopping distance. Use
tires of the recommended load
capacity for your vehicle. Never
overload them.
Department of Transportation
Uniform Tire Quality Grades
The following tire grading categories
were established by the National
Highway Traffic Safety Administration.
The specific grade rating assigned by
the tire's manufacturer in each
category is shown on the sidewall of
the tires on your vehicle.
Driving
5
179

All passenger car tires must conform to
Federal safety requirements in
addition to these grades.
Treadwear
The Treadwear grade is a comparative
rating, based on the wear rate of the
tire when tested under controlled
conditions on a specified government
test course. For example, a tire graded
150 would wear one and one-half
times as well on the government
course as a tire graded 100. The
relative performance of tires depends
upon the actual conditions of their
use, however, and may depart
significantly from the norm due to
variations in driving habits, service
practices, and differences in road
characteristics and climate.
Traction Grades
The Traction grades, from highest to
lowest, are AAA, A, B, and C. These
grades represent the tire's ability to
stop on wet pavement, as measured
under controlled conditions on
specified government test surfaces of
asphalt and concrete. A tire marked C
may have poor traction performance.
WARNING!
The traction grade assigned to this tire
is based on straight-ahead braking
traction tests, and does not include
acceleration, cornering, hydroplaning,
or peak traction characteristics.
Temperature Grades
The temperature grades are A (the
highest), B, and C, representing the
tire's resistance to the generation of
heat and its ability to dissipate heat,
when tested under controlled
conditions on a specified indoor
laboratory test wheel. Sustained high
temperature can cause the material of
the tire to degenerate and reduce tire
life, and excessive temperature can
lead to sudden tire failure. The grade
C corresponds to a level of
performance, which all passenger car
tires must meet under the Federal
Motor Vehicle Safety Standard No.
109. Grades B and A represent higher
levels of performance on the
laboratory test wheel, than the
minimum required by law.
WARNING!
The temperature grade for this tire isestablished for a tire that is properly
inflated and not overloaded. Excessive
speed, under-inflation, or excessive
loading, either separately or in
combination, can cause heat buildup
and possible tire failure.
Tire Pressure
Proper tire inflation pressure is
essential for safety and best
performance of your vehicle. The tire
pressure monitoring system “TPMS”
setup on the vehicle (see “Tire Pressure
Monitoring System” in this section)
may alert the driver about insufficient
tire pressure even though the driver is
responsible for regularly checking the
tire pressure.
Radial tires fitted on the vehicle may
look properly inflated even when they
actually are under inflated. Do not
make a visual judgment when
determining proper inflation.
Three primary driving aspects are
affected by improper tire pressure:
Safety
WARNING!
•Improperly inflated tires can be
dangerous.
Driving

180

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.
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.
YourAuthorized Maserati Dealeris
available to provide suggestions as tothe 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 any
tire on the vehicle.
•Never exceed the maximum speed
rating of the tires. Risk of accident
and serious personal injury due to
excessive speed.
Driving

•Failure to equip your vehicle with
tires having adequate speed
capability can result in tire failure.
CAUTION!
Replacing original tires with tires of a
different size may result in false
speedometer and odometer readings.
Winter Tires
These tires are specially designed for
driving on snow and ice and are fitted
to replace the ones supplied with the
vehicle. Winter or all-season tires can
be identified by the M+S (Mud &
Snow) or 3PMSF (3 Peaks Mountain
Snow Flake) designation on the tire
sidewall.
Before mounting winter tires, contact
anAuthorized Maserati Dealerto
receive the technical information
necessary to advise you on wheel and
tire compatibility.
As to the type of tires to use, inflation
pressures and winter tires
specifications, carefully follow the
indications as reported in the
“Technical Data” and “Tire Inflation
Pressure” chapters in section “Features
and Specifications”.
WARNING!
The standard tires profile and rubber
mixture are optimized for wet and dry
driving conditions. Standard tires may
not prove favorable for snow
conditions.
NOTE:
Snow tires should have the same load
capacity as original equipment tires
and should be mounted on all four
wheels.
Snow Chains
Maserati approved traction devices (or
snow chains) may be used to improve
traction on compacted snow in heavy
snow conditions.
The use of snow chains is specified by
local regulations of each country.
Use snow chains of reduced
dimensions, with a maximum
projection of 0.35 in (9 mm) beyond
the tire tread.
Maserati recommended to use snow
chains KONIG, type “Supermagic”.
The snow chains may be fitted only on
rear wheel tires.
Please, contact your Service for further
information.Check the snow chain tension after
driving for a distance of about 55 yd
(50 m) with the chains fitted.
With the snow chains fitted, it is
advisable to deactivate the ESC system
(see chapter “Drive Mode” in this
section).
CAUTION!
• The use of non-recommended snow
chains may damage the vehicle.
• Broken chains can cause serious
damage. Stop the vehicle
immediately if noise occurs that
could indicate chain breakage.
Remove the damaged parts of the
chain before further use.
• Do not exceed 30 mph (50 km/h).
• Drive cautiously and avoid severe
turns and large bumps, especially
with a loaded vehicle.
• Avoid holes in the road, do not drive
over steps or sidewalks and do not
drive on long stretches without
snow. This will prevent damage to
the vehicle and the roadbed.

that prevent the TPMS from
functioning properly. Always check the
TPMS malfunction telltale after
replacing one or more tires or wheels
on your vehicle to ensure that the
replacement or alternate tires and
wheels allow the TPMS to continue to
function properly.
General Information
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 at the base
of the rear door pillar.
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 lowtemperature 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.
The TPMS monitors the tire pressure
by means of special sensors fitted
inside the wheel rims, in position with
the inflation valve.
These sensors transmit a signal that is
detected by the antenna integrated in
the ECU.
The ECU processes this information
and, via the CAN line, transmits a
series of tire pressure data and system
errors, if any, to the instrument cluster.
The display may show the information
received by means of specific screen
pages, which can be recalled by
pressing briefly the "MODE" button
(see "TFT Display: Controls" in chapter
"Instrument Cluster" of the section
Dashboard Instruments and
Controls").
WARNING!
The TPMS warns the driver that the
tire pressure has decreased. This
warning does not exempt the driver
from periodically checking the tires
and from complying with the
prescribed tire pressure levels.
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 occur when
using replacement equipment that is
not of the same size, type, and/or

style. Aftermarket wheels can cause
sensor damage. Do not use
aftermarket tire sealants or balance
beads, as damage to the sensors may
result.
• The system can temporarily
experience radio-electric interference
emitted by devices using similar
frequencies.
• After inspecting or adjusting the tire
pressure, always reinstall the valve
stem cap. This will prevent moisture
and dirt from entering the valve
stem and damage the TPMS internal
sensor.
NOTE:
•Driving on a significantly
underinflated tire causes the tire to
overheat and may lead to tire failure.
Under-inflation also reduces fuel
efficiency and tire tread life, and may
affect the vehicle’s handling and
stopping ability.
•The TPMS is not a substitute for
proper tire maintenance, and it is the
driver’s responsibility to maintain
correct tire pressure using an
accurate tire pressure gage, even if
under-inflation has not reached thelevel to trigger illumination of the
TPMS light
.
•Seasonal temperature changes will
affect tire pressure, and the TPMS
will monitor the actual tire pressure
in the tire.
Viewing Messages on the
Display
By pressing repeatedly the “MODE”
button of the control panel on left
side of the steering column, the user
can access the information page that
shows the pressure values of each tire
(“Tire Pressure” screen page: see
paragraph "TFT Display: Screen Pages"
in chapter "Instrument Cluster" of
section "Dashboard Instruments and
Controls").
If system faults or low pressure is
detected on a not indentified tire,"Check Tire Pressure" or "TPMS
Malfunction" pop-up message will be
displayed for 10 seconds. The
amber warning light will
permanently illuminate on the right
side of the instrument cluster display.
With a malfunction detected, the "Tire
Pressure" screen page will not be
available while will be available the
calibration screen page.
The “Tire Pressure” screen page
becomes available again, until the
malfunction is corrected.
Low Tire Pressure Conditions
The signal transmitted by the ECU
activates messages and symbols on the
TFT display with two priority levels
corresponding to the following
thresholds:
• Soft Warning: if the pressure is 10%
lower than the rated pressure;
• Hard Warning: if the pressure is 17%
lower than the rated pressure.
The system refers to the rated pressure
acquired after calibration.
The two alarm thresholds for
monitoring the tire pressure
respectively activate the following
alerts:
• “Check tire pressure” illuminates on
the display when the pressure of one
