2020 MASERATI GRANTURISMO transmission

Drive Mode
Controls Preview
Drive modes can be set using the
buttons on central console, below the
A/C controls.
Buttons on the central console have
following functions:
• SPORT: to activate/deactivate a
sportier drive mode. In this mode,
the vehicle has a faster throttle
response and suspension/ESC sport
calibration (not recommended on
wet/slippery surfaces).
• ICE (low-grip): to activate/deactivate
the drive mode to ensure increased
control on slippery surfaces as well
as higher energy efficiency.
•
(ESC Off): to exclude/reactivate
the ESC system.• PARK OFF: to deactivate/reactivate
the automatic activation of the
Electric Parking Brake (EPB).
The active mode (in the example:
SPORT) is shown on the instrument
cluster display.
The drive mode can be selected only
with the key in the ignition switch in
MAR (ON)position, even while
driving. For each mode there are
various vehicle settings, that are
automatically set by the system in
relation to the traveling speed, engine
rpm, accelerator position, speed with
which the pedal is depressed as well as
the traveling conditions (uphill,
downhill, curves).
Use the Drive Mode Buttons
Drive modes can be set using the
buttons on central console.Buttons only have two statuses: OFF
and ON. The OFF status (button
released) is the standard function
mode. The ON status is activated by
pressing the button, the dedicated
LED on the button will illuminate.
Unlike the others, the
(ESC Off)
button must be pressed for at least 2
seconds. The SPORT and ICE (low-grip)
modes can be selected both when the
transmission is set to automatic
(AUTO) and to sequential manual
(MANUAL) operation.
NORMAL/SPORT Mode
SPORT mode is activated by pressing
the button "SPORT" on the central
console; the word “SPORT” will
illuminate on the instrument cluster
display.
To return to NORMAL mode from
SPORT mode, press the button again.
Whenever the engine is started, the
system automatically activates
NORMAL mode, even if SPORT mode
was selected before the engine was
last turned off.
NORMAL mode is intended specifically
for comfortable and fuel-economy
driving (low longitudinal and lateral
acceleration); the gears are shifted
with minimum rpm in lowest noise
Driving
5
159

(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
Driving
5
160

can be activated at any time and the
system limits the engine speed rate to
3000 rpm in all gears except for the
6th, unrequested gearshifts could take
place.
In any case, it is advisable to
deactivate SPORT mode before
selecting ICE (low-grip) mode.
When sequential manual gearshifting
is active, regardless of the mode set
(NORMAL / SPORT / ICE), the
transmission will automatically upshift
or downshift when reaching the
minimum and maximum rpm. This is
to prevent engine overrevving or
underrevving.
(ESC Off) Mode
The ESC system is designed to
automatically activate every time the
engine is started and can be
deactivated by pressing
(ESC Off)
button on the central console for
about 2 seconds. The
(ESC Off)
amber warning light illuminates on
the instrument cluster as well as on
the display, where it is accompanied
by a specific message.
The ESC (Electronic Stability Control)
antiyawing system incorporates all of
the vehicle control systems: ABS, EBD,
ASR and MSR (see "Brake and StabilityControl System" in this section for
further information).
The system is fitted with a unit that
predicts the vehicle behavior with
extreme accuracy. The system can
detect when the driver is about to lose
control of the vehicle. In this case, it
can activate the brake calipers
individually and engine control, in
order to create a torque sufficient to
resist the vehicle’s yawing moment.
Press
(ESC Off) button again to
reactivate the system.
The
(ESC On) amber warning light
on the instrument cluster flashes
during all the operating phases.
, the system is automatically disabled
and cannot be re-activated. While
driving, this condition is signaled by
the
(ESC On) amber warning light,
that illuminates both on the
instrument cluster as well as on the
multi-function display, where it is
accompanied by the message “ESC
unavailable go to dealer”.
When the engine is started, the system
malfunction is indicated by the
illumination of the
(ESC On) amber
warning light.
CAUTION!
• In the event of a fault, and with the
ESC system disabled (
(ESC Off)
button pressed), the vehicle behaves
as if it were not equipped with this
system: however, we recommend
you contact theAuthorized Maserati
Dealeras soon as possible to have
the system checked.
• If you have to tow the vehicle with 2
wheels raised, make sure the key in
the ignition switch is in theSTOP
(OFF)position. Otherwise, with the
ESC system active (
(ESC Off)
button not pressed), the control unit
will store a malfunction with
consequent illumination of the
(ESC On) amber warning lights on
the instrument cluster and on the
display. Should this occur, contact
theAuthorized Maserati Dealerto
have the system repaired.
• In low- and medium-grip conditions
(e.g., rain, snow, ice, sand, etc.) it is
advisable not to activate SPORT
mode, even with the ESC system
active (
(ESC Off) button not
pressed).

(Continued)
• Driving on parabolic curves will
deactivate the system.
PARK OFF Mode
To deactivate manual operation of the
parking brake, with the engine on,
press the "PARK OFF" button on the
central console. The words “PARK
OFF” appear on the instrument cluster
display for 5 seconds, after which they
remain displayed but in smaller size.
To reactivate automatic operation,
press the "PARK OFF" button once
again, the words “PARK ON” appear
on the display for 5 seconds.
CAUTION!
• In certain conditions when the
battery voltage is low, the electric
parking brake system may
temporarily be deactivated for safety
reasons. Therefore, typically upon
starting the engine, when the
battery voltage drops, the message
“PARK OFF” may temporarily be
displayed on the instrument cluster,
indicating that automatic operation
is temporarily disabled.• In the case of performance starting,
check that the electric parking brake
is disengaged.
For further information see "Parking
Brake" in this section.
Sequential Manual Operation
(MANUAL)
In this mode, the transmission interacts
with the driver in order to allow
manual shift and ensure increased
control of the vehicle. The current
mode allows the gear system to
optimize the engine brake action,
remove undesired shifting into higher
and lower gears and improve the
overall performance of the vehicle.
With automatic transmission selected
(D (Drive) position), shift the
transmission shift lever to position “+”
o “–”.
When this mode is selected, the
symbol “+” or “–” illuminates on the
gear display, based on the position of
the transmission shift lever, and the
gear engaged is shown on the
instrument cluster display.
WARNING!
When sequential manual operation isselected, upshifting or downshifting
must be performed manually.
To engage the gears, shift the
transmission shift lever to one of the
following two positions:
"+" (UP) to engage a higher gear;
"–" (DOWN) to engage a lower gear.
CAUTION!
• However, some conditions will
remain automatically controlled, for
example, when the engine is
overrevving or underrevving, the
system automatically engages a
higher or lower gear.
• If you request a gearshift in
conditions where the engine is
overrevving or underrevving, the
system will not accept the command.
• The ECU is programmed to control
one gearshift at a time, therefore,
fast and repeated actions will not
necessarily result in a gearshift. A
higher or lower gear is engaged only
if the previous procedure requested
has been completed.
When the system refuses to engage a
gear, an acoustic signal will sound for a
few seconds.
Driving
5
162

Sequential manual operation can only
be selected from the D (Drive) position
whatever the function (SPORT,
NORMAL) active at the time of the
request. The gear selected by the
automatic transmission will remain
engaged when the transmission shift
lever is moved.
Shifting the lever back to D (Drive),
automatic operation will instantly be
resumed, and a gear will be engaged
based on the driving style and mode
selected.
In the event of a failure of the
sequential manual gearshift system,
the transmission ECU will select
automatic operation.
Gearshift Paddles Operation
In sequential manual operating mode
(MANUAL), upshifting and
downshifting can be controlled not
only with the transmission shift lever
but also with the two paddles
positioned behind the steering wheel.
"+": (UP): upper gearshift paddle.
"–": (DOWN): lower gearshift paddle.Also in automatic transmission mode,
when the transmission lever is in
position D (Drive), you can shift to a
different gear by moving one of the
paddles. This action will temporarily
switch the system to sequential
manual operation.
If you then keep to a constant driving
style (low longitudinal and lateral
acceleration), the gearbox
automatically switches back to
automatic operation.
Gear Shift Indicator Light
In order to improve fuel economy, we
recommend that you shift gears when
the system prompts you to do so. This
will help reduce fuel consumption
without significantly affecting vehicle
performance.
The arrow icon beside the displayed
gear will light up to indicate the
moment the gear change is required.This indicator lights up just before
reaching the required speed for gear
change.
When the new gear is engaged, the
indicator turns off. If the shift runs
late or is not performed at all, the
indicator remains lit for a few seconds
then turns off. As soon as new
conditions requiring further gear
change occur, the indicator light will
illuminate again.
NOTE:
The gearshift indicator will only work
when the transmission is set to manual
sequential operation (see paragraph
"Sequential Manual Operation
(MANUAL)" in this chapter).

Parking Brake
The vehicle is equipped with an
electric automatic parking brake, also
called EPB (Electric Parking Brake).
It can be automatically engaged when
the engine is turned off and it is
disengaged when, with the engine
running, the accelerator pedal is
depressed.
When the parking brake is applied
(with the key in the ignition switch in
STOP (OFF)position), the
indicator lights up on the rev.
counter display and the related
message is displayed on the instrument
cluster for 5 seconds (see “Instrument
Cluster” in section “Dashboard
Instruments and Controls”).
During engagement and
disengagement procedures, the
indicator flashes until theparking brake has reached its
maximum activation force and is
respectively fully released.
The parking brake is automatically
applied when the engine is turned off
and the vehicle is stationary.
It can only be disengaged when the
engine is restarted.
If the key has been removed from the
ignition switch or is turned inSTOP
(OFF)position, it cannot be
disengaged.
Manual Engagement/
Disengagement
The parking brake can also be
manually engaged or disengaged
when the engine is running and when
the vehicle is moving or the key in the
ignition switch is inMAR (ON)
position, by pressing the brake pedal
and raising the lever located next to
the transmission shift lever.
When the parking brake is applied, the
indicator lights up on the rev.
counter and the related message will
be displayed on the instrument cluster.
If the engine was turned off when the
automatic engagement device was
deactivated (see “Deactivating
Automatic Operation” in this chapter)
it is possible to shift the parking brake
simply by pulling the lever upward.
CAUTION!
The main function of the EPB is to
allow safe parking of the vehicle,
therefore it must only be applied
when the vehicle is already stationary.
If the EPB is used while the vehicle is
moving and decelerating until a speed
lower of 3 mph (5 km/h) and, in
particular, until complete stop
(typically in a sudden brake), it is
necessary to have the EPB system
checked by anAuthorized Maserati
Dealer.
WARNING!
•Always hold the brake pedal pressed
during engagement or
disengagement of the parking brake.

Parking Brake” in section “In an
Emergency”).
• “Parking Brake system revision: go to
dealer”
The EPB system requires
maintenance, therefore contact an
Authorized Maserati Dealerto have
the system corrected.
WARNING!
In the event of an EPB failure, take
your vehicle to the nearest Authorized
Maserati Dealer as soon as possible.
Initialize the EPB System after a
Battery Disconnecting
After the detachment and the
subsequent connection of the battery,
on the instrument cluster display the
warning light will light up.
To initialize the EPB system lift, release
and lift again the lever located next to
the transmission shift lever.
Emergency Disengagement
In case of brake lock with complete
electrical system failure, it is necessary
to act on the electric actuator using
the special tool provided in the tool kit
to release the pressure of the parking
brake shoes (see “Emergency Releaseof the Parking Brake” chapter in
section “In an Emergency”).
EPB Operation with
Overheated Brakes
Driving on mountain roads with steep
slopes or a sports use of the vehicle
could overheat the brake system
components. In these conditions,
parking brake must not be used since
the push of the power actuator might
not be sufficient to ensure vehicle
braking, especially on a slope.
Drive normally without braking to
allow the brakes to cool down a few
minutes before stopping. In this way,
the automatic or manual activation of
the parking brake will ensure vehicle
braking.
Parking
Straighten the wheels and turn off the
engine.
Before leaving the vehicle, make sure
that the parking brake is fully applied
in automatic or manual mode and
place the transmission lever in the P
(Park) position.
Remove the key from the ignition
switch.
WARNING!
•Always check that the vehicle is
locked before leaving it.
•Never leave children unattended in
the vehicle.
•Do not park the vehicle on paper,
grass, dry leaves or other flammable
materials. They could catch fire if
they come into contact with hot
parts of the exhaust system.
•Do not leave the engine running
while the vehicle is unattended.
CAUTION!
When you need to park the vehicle on
a steep slope, both with the engine on
and off, it is recommended not only to
Driving
5
166

engage the parking brake, but also to
shift the transmission shift lever to P
(Park) before leaving the vehicle.
When parking on hill roads, it is
important to turn the front wheels
toward the curb on a downhill grade
and away from the curb on an uphill
grade.
Apply the parking brake before
placing the shift lever in P (Park),
otherwise the load on the
transmission locking mechanism may
make it difficult to move the shift
lever out of P (Park).
In certain conditions, it is however
advisable to disengage the parking
brake manually and slightly apply the
service brake for starting off. This is
advisable when there are obstacles
very close to the vehicle in the
direction in which you intend to move.
Brake and Stability
Control System
The vehicle is equipped with an
Electronic Stability Control (ESC)
anti-yawing system, which helps to
maintain directional control in the event
of loss of grip of the tires. The system is
able to detect potentially dangerous
situations for the stability of the vehicle
and automatically sets the brakes on all
four wheels in a differentiated manner,
in order to provide a torque settlement
of the vehicle.
ESC includes the following subsystems:
• ASR (Anti-Slip Regulation)
• ABS (Anti-lock Braking System)
• EBD (Electronic Brake-force
Distribution)
• HBA (Hydraulic Brake Assistance)
• BOS (Brake Override System)
WARNING!
•These systems cannot prevent the
natural laws of physics from
affecting the vehicle, nor can they
increase traction, braking or steering
efficiency beyond that afforded by
the condition of the vehicle brakes
and tires.•These systems cannot prevent
collisions, including those resulting
from excessive speed in turns,
following another vehicle too
closely, or hydroplaning.
•The capabilities of a vehicle
equipped with these systems must
never be exploited in a reckless or
dangerous manner that could
jeopardize the driver’s and the
passenger’s safety or the safety of
others.
Electronic Stability Control
(ESC)
This system enhances directional
control and stability of the vehicle
under various driving conditions. The
ESC corrects over steering and under
steering of the vehicle by applying the
brake to the appropriate wheel.
Engine power may also be reduced to
assist in counteracting the conditions
of instability and maintain the right
direction. The system is also able to
reduce the engine power.
Through sensors fitted on the vehicle,
the ESC system detects the driver’s
chosen direction comparing it to the
one maintained while running. In case
of discrepancy between the required
trajectory and the current one, the
