2020 MASERATI GRANTURISMO CONVERTIBLE snow chains

ESC system brakes the appropriate
wheel to counteract over or under
steering.
• Oversteer - when the vehicle is
turning more than appropriate for
the steering wheel position.
• Understeer - when the vehicle is
turning less than appropriate for the
steering wheel position.
The ESC system has two available
operating modes:
ESC On
This is the normal ESC operating mode.
At each start-up of the vehicle, the ESC
system is set in this mode and should
be used for most driving conditions.
The ESC should only be turned off for
specific reasons as pointed out in the
following paragraphs.
ESC Off
The “ESC Off” mode is aimed for a
more spirited driving experience but
also purposeful for driving in deep
snow, sand, or gravel. The current
mode disables the traction control
portion of the ESC and raises the
threshold for ESC activation, allowing
higher wheel spin than normally
granted by the ESC system. The
(ESC
Off) button is fitted in front of the
transmission shift lever: to deactivatethe system see “Drive Mode” in this
section.
WARNING!
In SPORT mode the ESC control
thresholds are higher for maximum
performance on dry road surface. To
ensure maximum security of the ESC is
recommended not to activate SPORT
mode on surfaces with medium- and
low-grip (e.g., wet, snow, dirt, etc..)
with ESC system active (button
(ESC
Off) not pressed).
NOTE:
To improve the vehicle's traction when
driving with snow chains, or when
starting off in deep snow, sand, or
gravel, it may be desirable to switch to
the “ESC Off” mode by pressing the
(ESC Off) button and remain in this
operational mode no longer than
needed. Once the situation requiring
“ESC Off” mode is overcome, turn the
ESC on again by pressing the
(ESC
Off) button. This may also be
performed while in motion.
Anti-Slip Regulation (ASR)
The ASR incorporated in the ESC
system avoids skidding of the driving
wheels during acceleration by means
of the engine control unit (spark
advance delay, engine throttle
opening reduction and fuel injection
cut) and the rear brakes.
The ASR system is designed to enhance
vehicle stability and active safety while
driving, especially under the following
conditions:
• internal wheel skidding on curves
due to the load dynamic variations or
excessive acceleration;
• excessive power transmitted to the
wheels, also in relation to the road
surface conditions;
• acceleration on slippery, snowy or icy
road surfaces;

•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
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.

NOTE:
TheAuthorized Maserati Dealercan
provide you with all information about
the Maserati Snow Chains, available in
the "Genuine Accessories" range.Tire Pressure Monitoring
System - TPMS
Guidelines
Each tire (including the spare tire, if
provided) should be checked monthly.
Tires should be checked when cold and
inflated to the inflation pressure
recommended by the vehicle
manufacturer indicated on tire
inflation pressure label (applied on the
driver's rear door pillar) and in “Tire
Inflation Pressure” of section “Features
and Specifications”.
If your vehicle has tires of a different
size than the size indicated on the
vehicle placard or tire inflation
pressure label, you should determine
the proper tire inflation pressure for
those tires.
As an added safety feature,
your vehicle has been
equipped with a tire pressure
monitoring system (TPMS) that
illuminates a low tire pressure telltale
when one or more of your tires is
significantly under-inflated.
Accordingly, when the low tire
pressure telltale illuminates, you
should stop and check your tires as
soon as possible, and inflate them to
the proper pressure. Driving on asignificantly under-inflated tire causes
the tire to overheat and can lead to
tire failure. Under-inflation also
reduces fuel efficiency and tire tread
life, and may affect the vehicle’s
handling and stopping ability.
Please note that the TPMS is not a
substitute for proper tire maintenance,
and it is the driver’s responsibility to
maintain correct tire pressure, even if
under-inflation has not reached the
level to trigger illumination of the
TPMS low tire pressure telltale.
Your vehicle has also been equipped
with a TPMS malfunction indicator to
indicate when the system is not
operating properly.
The TPMS malfunction indicator is
combined with the low tire pressure
telltale. When the system detects a
malfunction, the telltale will flash for
approximately one minute and then
remain continuously illuminated. This
sequence will continue upon
subsequent vehicle start-ups as long as
the malfunction exists. When the
malfunction indicator is illuminated,
the system may not be able to detect
or signal low tire pressure as intended.
TPMS malfunctions may occur for a
variety of reasons, including the
installation of replacement or
alternate tires or wheels on the vehicle

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

approximately 44 lb (20 kg) being
placed on the handle of the wrench
supplied when extended for use.
•After refitting the standard wheel,
check the tire pressure.
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).
NOTE:
The used wheel may soil the mats if it
is housed in the car: insert the used
wheel in the protective bag housed in
the side pocket of the covering bag.
To Refit the Standard Wheel with
Repaired 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). This is
equivalent to a load of
approximately 44 lb (20 kg) being
placed on the handle of the wrench
supplied when extended for use.
•After refitting the standard wheel,
check the tire pressure.
Once finished:
• completely deflate the compact
spare wheel by pressing on the valve
with the overhang of the valve cap;
• wrap the power cable and the
inflation hose inside the compressor
case;
• place the compressor, the jack, the
wrench and the adapter in the
