clutch MASERATI GRANTURISMO CONVERTIBLE 2019 Owners Manual

(gears are shifted at low engine
speeds).
In NORMAL mode, the system
controlling suspension damping uses a
shock absorber "softer" setting (see
"Skyhook Suspension" in section
"Understanding the Vehicle").
As SPORT mode has a lower priority
than ICE (low-grip) mode, if this is
already active when activating SPORT
mode, the system will ignore the
command.
CAUTION!
• Vs NORMAL mode, SPORT mode is characterized by faster gearshifting,
electronic suspension management
(Skyhook), opening of by-pass
exhaust valves (above 3000 rpm with
the vehicle in motion).
• In addition to enhancing performance, opening of the exhaust
also increases noise levels of the
vehicle.
In SPORT mode, fast gearshifting
however
, always depends on the
accelerator pedal travel and on the
engine rpm, as in NORMAL mode.
When in SPORT mode, the system
controlling suspension damping uses a
shock absorber "harder" setting (see "Skyhook Suspension" in section
"Understanding the Vehicle").
In MANUAL mode, DOWN-shifts with
the accelerator pedal released, will
have a braking effect approaching the
skidding limit of the driving wheels on
dry asphalt.
Under sports-style driving conditions
with gearshifts at high engine rpm,
double-clutching when up-shifting is
performed automatically.
WARNING!
It is advisable not to use SPORT mode
on roads with low or medium grip
conditions (e.g. ice, snow, or wet
roads) as the driving wheels could skid
during gearshifts.
Therefore, excessive use of the vehicle
in SPORT mode is advisable only on
race tracks.
If you use MANUAL and SPORT mode
in
combination for sports-style driving,
when starting-off or shifting gears,
you may perceive an initial slipping of
the driving wheels even on dry roads.
ICE (low-grip) Mode
This mode can be used on particularly
slippery road surfaces (e.g., rain, snow,
ice). To activate/deactivate this mode, press button "ICE" on the central
console. The word “ICE” will illuminate
on the instrument cluster display.
In “low-grip” mode, the system uses
2nd instead of 1st gear; this means
that 2nd gear will automatically be
engaged (gearshift lever in D (Drive)
position) in the event of standing
starts in automatic mode; on the other
hand, when in sequential manual
mode (transmission lever in MANUAL
"+"), moving the transmission lever
from N (Neutral), or R (Reverse) or
when the vehicle stops, 2nd gear will
automatically be engaged.
When sequential manual mode is
selected with 2nd gear engaged, a
downshift request will be ignored.
While driving, the system
automatically switches to the upper
gear if the engine reaches the
preestablished speed rate (3000 rpm).
ICE (low-grip) mode has priority over
SPORT mode and assists the ESC
system.
WARNING!
A downshift request from 6th to 5th
gear will only be accepted if the
engine speed rate in 5th gear is lower
than 3000 rpm. As ICE (low-grip) mode

Vehicle Stored for Long
Periods
If the vehicle is going to be stored for
over a month, follow the below
precautions:
• Wash and dry the vehiclethoroughly.
• Store the vehicle in a covered, dry and, if possible, ventilated area.
• Select P (Park) and turn off the engine.
• Turn the key in the ignition switch in STOP (OFF) position.
• Disconnect the battery (refer “Maintenance-Free Battery” in this
section) or connect a battery charger
(refer to paragraph “Maintaining
Battery Charge” of chapter “Battery
Statement” in this section).
• Check the battery charge status. During parking, this check must be
carried out every three weeks.
Recharge the battery if the open
circuit voltage is lower than 12.2 V.
• Check that the parking brake is NOT engaged.
• Do not empty the engine cooling system.
• Clean and protect the painted parts applying protective wax. • Clean and protect polished metal
parts with special products available
on the market.
• Talc the windshield wiper blades and raise them from the windshield.
• Cover the vehicle with a long cloth in breathable fabric (available from
the Authorized Maserati Dealer ). Do
not use thick plastic sheets, which do
not allow the humidity on the
vehicle surface to evaporate.
• Inflate the tires up to a pressure which must be 1 bar (14.5 psi) higher
than the normally prescribed one,
and check it at regular intervals.
NOTE:
The Authorized Maserati Dealer can
provide you with any information
about the available “Indoor and
Outdoor Car Covers”, available in the
“Genuine Accessories” range.
WARNING!
The tire pressure must be brought
back to the prescribed value before
reusing the vehicle (see “Tire Inflation
Pressure” in section “Features and
Specifications”).
Restarting the Vehicle
Before restarting the vehicle after a
long period of inactivity, we
recommend that you carry out the
following operations.
• Check the tires for pressure and for any damages, cuts or cracks. If this is
the case, have them replaced.
• Do not dry-rub the external surface of the vehicle.
• Visually inspect if there are any fluid leaks (oil, brake and clutch fluid,
engine coolant etc.).
• Have the engine oil and filter replaced.
• Check the fluid levels in the brake system, as well as the engine coolant
level.
• Check the air filter and have them replaced if necessary.
• Reconnect the battery after checking the charge status (refer to
“Maintenance-Free Battery” in this
section) and perform the initializing
procedure if applicable.
• With the transmission in N (Neutral), let the engine idle for several
minutes.
