overall conditions should also be
checked monthly. Tire pressures
change by approximately 1 PSI (0.07
bar) per 12°F (7°C) of air temperature
change. Keep this in mind when
checking tire pressure inside a garage,
especially in winter.
Example: If garage temperature = 68°F
(20°C) and the outside temperature =
32°F (0°C) then the cold tire inflation
pressure should be increased by 3 PSI
(0.21 bar) for every 12°F (7°C) for this
outside temperature condition.
Tire pressure may increase from 2 to 6
PSI (0.13 to 0.4 bar) during operation.
DO NOT reduce this normal pressure
build-up or your tire pressure will be
too low. 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
valve stem and the TPMS sensor
connected to it.
Tread Wear Indicators Tread wear indicators are in the
original equipment tires to help you
determine when your tires should be
replaced.
These indicators are molded into the
bottom of the tread grooves. 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 equivalentDriving

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 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.
• 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
an Authorized Maserati Dealer to
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 0.23 in (6 mm) beyond
the tire tread.Driving

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 tire assemblies. After replacing all four
wheel and tire assemblies (road tires)
with tires not equipped with Tire
Pressure Monitoring System sensors,
drive the vehicle for 20 minutes above
15 mph (24 km/h). The TPMS will
chime, the TPMS light
will flash on
and off for 75 seconds and then
remain on and the instrument cluster
will display the “Service Tire Pressure
System” message and then display
dashes (--) in place of the pressure
values. Beginning with the next
ignition switch cycle, the TPMS will no
longer chime or display the “Service
Tire Pressure System” message in the
instrument cluster but dashes (--) will
remain in place of the pressure values.
To reactivate the TPMS, replace all
four wheel and tire assemblies (road
tires) with tires equipped with TPMS
sensors. Then, drive the vehicle for up to 20 minutes above 15 mph
(24 km/h). The TPMS will chime, the
TPMS light
will flash for 75 seconds
and then turn off. The instrument
cluster will then display the “Service
Tire Pressure System” message.
The instrument cluster will also display
pressure values in place of the dashes
(--). On the next ignition switch cycle
the “Service Tire Pressure System”
message will no longer be displayed as
long as no system fault exists.

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 on Snow or Ice
Please consider some general advice
for driving in these conditions, listed
below.
• Maintain a very moderate speed.
• Fit snow chains or specific tires if the
road is covered with snow: see the
paragraphs “Tires – General
Information” in this section.
• We recommend you to activate the
“I.C.E.” mode (see chapters “Drive
Mode” in this section).
• During the winter season, even
apparently dry roads can have icy
sections. Be careful when crossing
bridges, viaducts and roads that have
little exposure to the sun and are
bordered by trees and rocks. They
may be icy.
• Keep an ample safe distance from
the vehicles in front of you.
WARNING!
• Rapid acceleration on slippery
surfaces is dangerous. Unequal
traction can cause sudden pulling of
the driving wheels. You could lose
control of the vehicle and possibly
have a collision. Accelerate slowly
and carefully whenever there is likely to be poor traction (ice, snow,
wet mud, loose sand, etc.).
• Do not drive on or across a road or
path where water is flowing and/or
rising (as in storm run-off). Flowing
water can wear away the road or
path surface and cause your vehicle
to sink into deeper water.
Furthermore, flowing and/or rising
water can carry your vehicle away
swiftly. Failure to follow this
warning may result in injuries that
are serious or fatal to you, your
passengers, and others around you.
Although your vehicle is capable of
driving
through shallow standing
water, consider the following Cautions
and Warnings before doing so.
CAUTION!
• Always check the depth of the
standing water before driving
through it. Never drive through
standing water that is deeper than
47 in (150 mm).
• Determine the condition of the road
or the path that is under water and if
there are any obstacles in the way
before driving through the standing
water.Driving

Winter Tires
These tires are specially designed for
driving on snow and ice and are fitted
to replace the ones supplied with the
vehicle.
The specific features of the winter tires
lead to lower performance under
normal environmental conditions or
on long highway trips, compared to
the standard tires.
Therefore, their use should be limited
to the situations and performance for
which they have been type-approved.
The Authorized Maserati Dealer can
provide all necessary information
about fitting winter tires on the
vehicle.
NOTE:
• We recommend fitting winter tires
on the vehicle at temperatures below
45 °F (7°C) since the driving
performance of summer tires is
reduced at low temperatures.
Summer tires may be permanently
damaged at extremely low
temperatures.
• Comply with all state and local laws
governing snow tire and tread depth
requirements. Wheel Rims Maintenance All wheel trims should be cleaned
regularly with a mild soap and water.
To remove heavy soil and/or excessive
brake dust, use a nonabrasive,
non-acidic cleaner.
Do not use scouring pads, steel wool, a
bristle brush, or metal polishes.
Do not use oven cleaner that may
affect and damage the brake calipers.
Avoid automatic car washes that use
acidic solutions or harsh brushes that
may damage the wheel rim protective
finish.
Bodywork Maintenance
and Care Protection from Atmospheric
Agents The main causes of corrosion are:
• atmospheric pollution;
• salinity and humidity in the
atmosphere (marine areas or a damp
climate);
• seasonal environmental conditions;
• salt scattered on the roadbed to melt
ice and snow.
The abrasive action of wind-carried
atmospheric dust and sand, mud and
stones should not be underestimated.
On this vehicle, Maserati has adopted
the best technological solutions to
protect the bodywork from corrosion.
The main measures are:
• paint products and systems that give
the vehicle particular resistance to
corrosion and abrasion;
• use of galvanized (or pre-treated)
metal sheets which are highly
resistant to corrosion in the most
exposed parts;
• spraying of the underbody, engine
compartment, insides of wheel
housings, and other structures withMaintenance and Care
