2019 MASERATI GRANTURISMO winter tires

• 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.
When the tread is worn to one of the
tread wear indicators, the tire should
be replaced. 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
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 0.35 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. Driving

with the key removed to the ignition
switch.
• 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
“ICE” drive 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.
• Avoid sharp braking, sharp changes
in direction and rapid acceleration. Rapid acceleration on snow covered
or icy surfaces may cause the driving
wheels to pull erratically to the right
or left. This phenomenon occurs
when there is a difference in the
surface traction under the rear
(driving) wheels.
WARNING!
Rapid acceleration on slippery surfaces
is dangerous. Unequal traction can
cause sudden pulling of the rear
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.).
Driving through Flooded
Sections Driving through more than a
centimeters deep shallow standing
water section will require extra
caution to ensure passenger safety and
prevent damage to your vehicle.
WARNING!
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 Caution
and Warning 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
the bottom of the tire rims mounted
on the vehicle.
• 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

“Driving”). 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 features of these tires are
significantly reduced in winter when
tread depth is less than 0.157 in (4
mm). In this case, they should be
replaced.
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 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
