(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

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.

Use of the Engine
Breaking-In
Today's most modern production
methods are designed to provide
extremely precise construction and
assembly of components. However,
moving parts do undergo a settling
process, basically in the first hours of
vehicle operation.
Do not drive keeping at a constant
high speed rate for a prolonged time.
While cruising, brief full-throttle
acceleration within the limits of local
traffic laws contributes to a good
break-in. Wide-open throttle
acceleration in low gear can be
detrimental and should be avoided.
The engine oil installed in the engine
at the factory is a high-quality energy
conserving type lubricant. Oil changes
should be consistent with anticipated
climate conditions under which vehicle
operations will occur. For the
recommended viscosity and quality
grades, see “Refillings” in section
“Features and Specifications”.
A new engine may consume some oil
during its first few thousand
kilometers of operation. This should
be considered as a normal part of thebreak-in and not interpreted as an
indication of malfunction.
Avoid exceeding 5000 rpm for the first
620 trip mi (1000 km).
After starting the vehicle, do not
exceed 4000 rpm until the engine has
warmed up sufficiently (coolant
temperature: 149-158°F/65-70°C).
While Driving
Never travel with the tachometer
indicator approaching the peak rpm,
not even downhill. When the
tachometer indicator is approaching
the peak rpm (red colored zone), take
precautions to avoid exceeding that
limit.
Ensure proper operation of different
devices checking their respective
control telltales.
CAUTION!
• Under normal conditions, all red
warning lights on the instrument
cluster display should be off. When
they come on, they indicate a
malfunction. Refer to “Instrument
Cluster” in section “Dashboard
Instruments and Controls”.
• Continuing to drive when a red
warning light is on could cause
serious damage to the vehicle and
affect its performance.
WARNING!
Do not travel downhill with the
engine off, as the servo brake will no
longer function due to the vacuum
decrease and thus after a few braking
attempts, the system becomes totally
inefficient. The power steering will
also lose its efficiency under these
conditions.
Onboard Diagnostic System
Your vehicle is equipped with a
sophisticated onboard diagnostic
system. This system monitors the
performance of the emissions, engine,
