Maserati Dealer to 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 the engine/transmission assembly to fully
cool down.

(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) modeDriving
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 Stability Control 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 the Authorized Maserati
Dealer as 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 the STOP
(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
the Authorized Maserati Dealer to
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

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 Driving

• in the event of loss of grip on wet
roads (aquaplaning).
The ASR system works in combination
with the electronic suspension control
system: in normal conditions (SPORT
mode off), stability in low and
medium grip conditions has priority,
while with SPORT mode active, the
system favors traction, thereby
optimizing vehicle performance on dry
asphalt.
The ASR system is automatically
activated every time the engine is
started and can be deactivated by
pressing
(ESC Off) button (see
"Drive Mode" in this section).
ASR System Failure
In the event of a fault, the system is
automatically disabled and cannot be
re-activated. While driving, this
condition is signaled by the
amber
warning light on the instrument
cluster display, which illuminates
together with the message “ASR
unavailable go to dealer”. Also the
(ESC On) amber warning light
illuminates inside the tachometer with
the message indicating that the ESC
system is unavailable. In this case drive
with the greatest care and have the
system immediately checked by the
nearest Authorized Maserati Dealer . MSR Function
The ASR system also controls the
engine braking torque when the
accelerator pedal is released under
low grip conditions (e.g., snow, ice,
etc.): in these conditions, the high
braking torque provided by the
engine may cause instability of the
vehicle.
The system, using the same sensors as
the ABS, detects skidding of one or
both driving wheels when the
accelerator is released and opens the
motor-driven throttle of the engine
fuel system thereby reducing the
braking torque and re-establishing the
maximum grip conditions for the
driving wheels.
WARNING!
The maximum deceleration that can
be obtained with the engine brake
always depends on the tire grip on
the road surface. Snow or ice
obviously reduce grip values.
WARNING!
California Proposition 65

Anti-Lock Braking System (ABS)
and Electronic Brake-force
Distribution (EBD) The Anti-Lock Brake System (ABS)
provides increased vehicle stability and
brake performance under most
braking conditions. The system
automatically “pumps” the brakes
during severe braking to prevent
wheel lock-up.
The Electronic Brake-force Distribution
(EBD) prevents the rear wheels from
over-braking and provides greater
control of available braking forces
applied to the rear axle. Driving
5
169

WARNING!
The ABS helps prevent the wheels
from locking, but it does not increase
the physical grip limits between the
tires and the road. Therefore, always
keep a safe distance from the vehicle
in front of yours and reduce your
speed when entering a curve.
NOTE:
• When
the vehicle's speed is higher
than 7 mph (11 km/h), you may also
hear a slight clicking sound as well as
other motor noises. The system is
performing a self-check cycle to
ensure that the ABS is working
properly.
• This self-check occurs each time the
vehicle is started and accelerated
past 7 mph (11 km/h).
ABS is activated during braking under
certain road or stopping conditions.
ABS-inducing conditions can include
ice, snow, gravel, bumps, railroad
tracks, loose debris.
You may also experience the following
when the brake system goes into Anti-
Lock: • The ABS motor running (it may
continue to run for a short time after
the vehicle stops).
• The clicking sound of solenoid valves.
• Brake pedal pulsations.
• A slight drop or fall away of the
brake pedal at the end of the stop.
These are all normal characteristics of
ABS functioning.
WARNING!
• The ABS contains sophisticated
electronic equipment that may be
susceptible to interference caused by
improperly-installed or high-output
radio transmitting equipment. This
interference can cause possible loss
of anti-lock braking capability.
Installation of such equipment
should be performed by qualified
Maserati personnel.
• Pumping the Anti-Lock Brakes will
diminish their effectiveness and may
lead to a collision. Pumping brakes
makes the stopping distance longer.
Just press firmly and continuously on
your brake pedal when you need to
slow down or stop ABS and EBD System Failure
In
the event of a failure the ABS
system will be deactivated, but this will
not affect the efficiency of the
standard braking system.
The failure will be indicated by the
illumination of the
amber warning
light on the instrument cluster.
An EBD system failure is indicated by
the illumination of the
red
warning light on the instrument
cluster.
In this case we recommend that you
contact the nearest Authorized
Maserati Dealer in order to identify
the fault as soon as possible, by means
of the system self-diagnostic function.
WARNING!
• The
failure warning light usually
illuminates with the engine running
to indicate a malfunction in the ABS
system only. In this case, the braking
system will remain fully functioning,
but will not use the ABS. In these
conditions, also the EBD system
efficiency may be affected. Drive
with the greatest care in order to
avoid sudden braking and have the
system immediately checked by theDriving
5
170

nearest Centre of the Authorized
Maserati Dealer.
• The warning light illuminates
when the engine is running to
indicate an EBD system malfunction.
In this case, sharp braking may
cause an early locking of the rear
wheels, and the vehicle may skid.
Drive with the greatest care and
have the system immediately
checked by the nearest Centre of the
Authorized Maserati Dealer.
Hydraulic Brake Assistance
(HBA) HBA completes the ABS system by
optimizing the vehicle braking
capacity during emergency braking.
In the event of a critical situation,
where the vehicle must stop in the
shortest possible distance, the driver
usually depresses the brake pedal
quickly, but often not strongly
enough: this increases the braking
distance. HBA has been designed to
solve this problem and acts by
applying the maximum braking force
during emergency braking, in order to
stop the vehicle in the shortest
possible distance.
HBA recognizes the emergency
condition by analyzing some parameters, such as the pressure on
the brake servo, the wheel speed and
activation of the third stop. The ABS
control unit cross-checks this data and
substitutes the driver by activating the
braking system’s full power and so
ensures optimal braking performance
in the shortest possible distance.
Brake Override System (BOS) To complete the range of systems that
assist braking, the vehicle is equipped
with BOS , which is designed to stop
the vehicle even when it is being
accelerated. If the brake pedal is
depressed together with the
accelerator, the engine power should
be automatically reduced and, if the
driver continues to depress the
accelerator, the system may even cause
the vehicle to come to a complete
stop.
Additionally, if the brake pedal is
released when the accelerator is still
depressed, the corresponding engine
torque can be reached gradually.Using the Brakes CAUTION!
To obtain a good performance of
brake pads and discs, avoid sudden
braking during the first 190 mi
(300 km).
The pad wear limit is indicated by the
illumination
of the
warning light,
on the instrument cluster display.
In this event, please contact an
Authorized Maserati Dealer .
WARNING!
• Riding the brakes can lead to brake
failure and possibly an accident.
Driving with your foot resting or
riding on the brake pedal can result
in abnormally high brake
temperatures, excessive lining wear,
and possible brake damage. In an
emergency full braking capacity may
be impaired.
• If the
red warning light
illuminates when the engine is
running with the message that
indicates an insufficient brake fluid
level, stop the vehicle and check the
(Continued)Driving
5
171

(Continued)
brake fluid level immediately (see
"Maintenance Procedure" in section
“Maintenance and Care”). If fluid is
below the minimum level, top up
with the recommended fluid and
contact an Authorized Maserati
Dealer immediately to have the
system checked. Brake fluid leaks
affect the operation of the braking
systems.
• The brake system performance in
terms of active safety is not a reason
for the driver to run unnecessary
risks. The driving style shall always
be suited to weather conditions,
range of visibility and traffic.
• The maximum deceleration that can
be obtained always depends on the
tire grip on the road surface. With
snow or ice on the road the grip is
obviously reduced and the braking
distance is very high, even with the
ABS system.
Brake Pads and Brake Discs Wear on the brake pads and brake
discs depends to a great extent on the
driving style and the conditions of use
and therefore cannot be expressed in
actual kilometers driven on the road. The high-performance brake system is
designed for optimal braking effect at
all speeds and temperatures.
Certain speeds, braking forces and
ambient conditions (e.g. temperature,
humidity and long outdoor stopping
periods) can therefore cause the
brakes to "squeal". This is normal and
will cease after a few brakings.
New Brake Pads and/or Brake
Discs New brake pads have to be “broken
in”, and therefore only attain optimal
friction to the brake disc when the
vehicle has covered several
hundreds km.
During this first period, the slightly
reduced braking ability must be
compensated for by pressing the brake
pedal harder. This applies whenever
the brake pads and/or brake discs are
replaced.
Brake Overheating 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 on the brake shoes 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.Driving
