Safety
WARNING!
• Improperly inflated tires can be
dangerous.
• Under-inflation increases tire flexing
and can result in tire overheating.
• Over-inflation reduces a tire's ability
to cushion shock. Objects on the
road and potholes can cause
damage that results in tire failure.
• Over-inflated or under-inflated tires
can affect vehicle handling and can
fail suddenly, resulting in loss of
vehicle control.
• Unequal tire pressures can cause
steering problems.
• Unequal tire pressures from one side
of the vehicle to the other can cause
the vehicle to drift to the right or
left.
• Always drive with each tire inflated
to the recommended cold tire
inflation pressure.
Economy
Improper
inflation pressures may
cause uneven wear patterns to
develop across the tire tread. These
abnormal wear patterns will reduce tread life resulting in a need for
earlier tire replacement. Under-
inflation also increases tire rolling
resistance resulting in higher fuel
consumption.
Ride comfort and vehicle stability
Proper tire inflation contributes to a
comfortable ride. Over-inflation
produces a jarring and uncomfortable
ride.
Tire Pressure Checkup The proper cold tire inflation pressure
is indicated on the driver's side rear
door pillar and on the table “Tire
Inflation Pressure” in section
“Features and Specifications”.
Inflation pressure specified on the
table always refers to “cold tire
inflation pressure”. Cold tire inflation
pressure is defined as the tire pressure
after the vehicle has not been driven
for at least three hours, or driven less
than 1 mi (1.6 km) after a three hour
period.
Check tire pressures more often in
case of significant outside
temperature changes, as tire pressure
varies according to temperature
changes.
The pressure should be checked and if
necessary adjusted; tire wear and 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.Driving

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. The chains may be fitted only on 19”
rear wheel tires.
Please contact an Authorized Maserati
Dealer 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 snow chains can cause
serious damage. Stop the vehicle
immediately if noise occurs that
could indicate snow chain breakage.
Replace the damaged parts of the
snow 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.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

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. • Do not exceed 5 mph (8 km/h) when
driving through standing water. This
will minimize wave effects.
• Driving through standing water may
cause damage to your vehicle
drivetrain components. After driving
through standing water, do not drive
if you are not sure about drivetrain
condition. Such damage is not
covered by the New Vehicle
Warranty.
• Getting water inside your vehicle
engine can cause it to lock up and
stall out, and cause serious internal
damage to the engine. Such damage
is not covered by the New Vehicle
Warranty.
• After driving through standing
water always have the fluids (engine
oil, transmission oil, etc) checked for
contamination at an Authorized
Maserati Dealer .
WARNING!
• Driving through standing water
limits your vehicle traction
capabilities. Do not exceed 5 mph
(8 km/h) when driving through
standing water.

Insufficient tire inflating pressure can
cause tire overheating and possible
internal damage.
CAUTION!
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 it.
Impacts with curbs, holes, and
obstacles
in the road, and prolonged
trips on rough roads can cause tire
damage which may not be visible to
the naked eye.
Check your tires regularly for any signs
of damage (e.g. scratches, cuts, cracks,
bulges, etc.). If sharp objects penetrate
the tires, they can cause structural
damage which is only visible when the
tire is removed.
In any case, any possible damage must
be inspected by an experienced
technician, as it may seriously reduce
the tire life.
Remember that tires deteriorate with
time, even if used little or not at all.
Cracks in the tire tread and sides,
alongside possible bulging, are a sign
of deterioration. WARNING!
• Check the inflating pressure of the
tires when cold, at least every two
weeks and before long trips.
• Have old tires inspected by an
experienced technician, to make
sure they can still be used safely. If
the same tire has been on your
vehicle for 4 or 5 years, have it
inspected anyway by an
experienced technician.
• Never fit tires of uncertain origin.
• “Directional” tires have an arrow on
their side showing the rolling
direction. To keep the best
performance when replacing a tire,
make sure that the rolling direction
corresponds to the one shown by
the arrow.
• During the tire life, the rolling
direction used for the first fitting
should always be observed, also in
case of “nondirectional” tires.
• Check the depth of the tire tread at
regular intervals. The thinner is the
tread, the greater is the risk of
skidding.
• Drive carefully on wet roads to
decrease the risk of aquaplaning. 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.Maintenance and Care
