2020 MASERATI GRANTURISMO CONVERTIBLE Owners Manual

(Drive) to R (Reverse), and vice versa,
by pressing the unlock button on the
transmission shift lever.
• Vehicle moving: switching to N
(Neutral) from D (Drive) requires the
unlock button on the shift lever
pressed.
• From D (Drive) selected mode it is
always possible to switch to
MANUAL mode by shifting the
transmission shift lever to "+" or "–"
position.
The gears will be engaged 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).
The system has been programmed to
classify all driving styles, in relation to
the above mentioned parameters, and
to associate them with the various
vehicle settings, which go from
extremely comfortable and economic
driving to racing-style driving. The
setting is selected automatically.
At extremely cold temperatures
(-23°F/-30°C or below), transmission
may be affected by the low
temperature of the engine and
transmission. Normal operation will
resume once the transmissiontemperature has risen to a normal
level.
Transmission Strategy in
Particular Driving Situations
Downhill Driving
When the accelerator pedal is
released, the transmission system
detects that the vehicle is moving
downhill and deactivates upshifting.
When the accelerator pedal is
depressed, upshifting is reactivated
but will be delayed by a few seconds.
When the brake pedal is depressed,
the transmission system downshifts to
provide enhanced engine braking
power.
In other words, when driving
downhill, the transmission system
operates so as to avoid upshifting and
shifting gears when the accelerator
pedal is released, and delays gear
engagement by a few seconds when
the accelerator pedal is depressed.
In addition, when the brakes are
applied, it engages the lowest gear in
order to provide enhanced engine
braking power.
This strategy is aimed at making
downhill driving safer.Driving in Curves
The system detects when the vehicle
goes into a curve through the lateral
acceleration and the steering angle.
Detecting this condition, it controls
gearshifting using a specific mode.
This mode is exited when the vehicle
comes out of the curve, at a distance
that varies depending on the vehicle
speed.
Fast-off Strategy
When the accelerator pedal is fully
released, the system deactivates
upshifting.
The next time the pedal is depressed,
upshifting will be reactivated only
after a few seconds.
Upshifting is also deactivated when
the accelerator pedal is partially
released; the system waits the time
necessary to evaluate if the release
action is completed.
Hot-mode Situations
In the event that the engine oil or
coolant temperature is too high or
both, the transmission system reduces
the maximum engine speed to 4000
rpm.
Therefore, upshifting will occur at this
limit.
This strategy does not apply to
downhill driving, so as to always have
Driving

165

the efficiency of engine braking
together with the standard braking
system.
ESC System Operations
In order to prevent unstable driving
conditions, the ESC system may request
the transmission system to deactivate
gearshifting. The system handles this
request depending on the gear
engaged and on the rpm, and decides
whether to accept it or not.
Driving with Cruise Control
With the Cruise Control function
activated, the transmission system
selects such settings as to provide
enhanced comfort and fuel-economy.
MC Start Strategy
(for MC version only)
With the aim of optimizing standing
starts for performance driving (only
recommended for use in areas closed
to traffic and in accordance with the
Highway Code), the automatic
transmission system is equipped with
quick start strategy.
This strategy is activated when the
following conditions occur
simultaneously:
• AUTO and SPORT modes active;
•
ESC mode off;
• brake pedal depressed.In these conditions, the driver has the
possibility to accelerate and, keeping
the brake pedal depressed, keep the
vehicle standing until reaching an
engine speed between 2300 an 2500
rpm. Then, upon releasing the brake
pedal, have the best standing start
performance.
WARNING!
This strategy must only be used on
vehicles in areas closed to traffic, in
accordance with the Highway Code
and only by skilled drivers.
Transmission Malfunction and
Overheating Conditions
Transmission Failure
Transmission function is electronically
monitored to detect abnormal
conditions. If a condition that could
result in transmission damage is
detected, Transmission Limp Home
Mode will be activated. In this
situation, the transmission may
operate only in certain gears, or may
not shift at all.
CAUTION!
In these conditions, we recommendedthat you stop the vehicle and turn off
the engine for at least one minute.
When restarting the engine, the
self-diagnosis system may cancel the
malfunction, which will in any case be
recorded by the ECU.
A message and thewarning light
in the instrument cluster will inform
the driver about the transmission
failure.
In failure conditions, the transmission
shift lever can however be shifted to R
(Reverse), N (Neutral) and D (Drive)
position.
When shifting to D (Drive) position,
only a few gears will be available,
depending on the malfunction found.
CAUTION!
If a transmission failure is signaled,
take your vehicle to the nearest
Authorized Maserati Dealeras soon as
possible to have the problem
corrected.
If the failure is signaled when the
engine is started, it means that the
transmission ECU detected a fault
when the vehicle was last used. Also in
this case, take your vehicle to the
nearest Center of theAuthorized
Driving
5
166

Maserati Dealerto have the
transmission checked.
WARNING!
When the transmission is
malfunctioning, drive very carefully
considering that vehicle performance
is reduced. In addition, the reverse
gear safety lock may not be active:
absolutely do not shift the lever to R
(Reverse) when the vehicle is moving.
Transmission Oil Overtemperature
If the transmission oil temperature
exceeds the operating limit, a message
and the
red warning light
illuminates on the instrument cluster.
In this case, slow down until
temperature returns to normal level
(the light will turn off).
If this is not sufficient, we recommend
to stop the vehicle, shift the lever to
position P (Park) or N (Neutral) and
keep the engine idle until the
red
temperature warning light turns off
and the message disappears from the
display. Resume driving without
demanding high engine performance.
If the
red warning light and the
related message turns on again, it is
advisable to stop the vehicle, turn off
the engine and wait for theengine/transmission assembly to fully
cool down.

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
169

(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
170

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).
Driving

(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 is
selected, 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.
