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.
“Drive Away Inhibit” strategy In order to avoid a dangerous
condition resulting from leaving the
vehicle “not braked” with running engine and without driver on board,
“Drive Away Inhibit” strategy alerts
the driver with messages on the
instrument cluster display and
sounding chimes, then puts the
transmission in P (Park).
The table shows the vehicle condition
and the action that the system runs to
exit the dangerous condition.

Brake and Stability Control
System The vehicle is equipped with an
Electronic Stability Control System
(ESC), 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:
• ABS (Anti-lock Braking System);
• EBD (Electronic Brake-force
Distribution);
• TCS (Traction Control System);
• BAS (Brake Assist System);
• BTO (Brake Throttle Override);
• HSA (Hill Start Assist).
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 ESC
system brakes the appropriate wheel
to counteract over or under steering.
• Oversteer - when the vehicle is
turning more than appropriate for
the steering wheel position.
• Understeer - when the vehicle is
turning less than appropriate for the
steering wheel position.
The ESC system has two available
operating modes:
ESC on
This is the normal ESC operating mode.
At each start-up of the vehicle, the ESC
system is set in this mode and should
be used for most driving conditions.
The ESC should only be turned off for
specific reasons as pointed out in the
following paragraphs.
ESC off
The “ESC off” mode is aimed for a
more spirited driving experience but
also purposeful for driving in deep
snow, sand, or gravel. The current
mode disables the TCS portion of the
ESC and raises the threshold for ESC
activation, allowing higher wheel spin
than normally granted by the ESC
system. The
(ESC OFF) button is
fitted beside the gear shift lever: toDriving

248

deactivate the system see “Drive
Mode” in this section.
WARNING!
In SPORT mode the ESC control
thresholds are higher for maximum
performance on dry road surface. To
ensure maximum security of the ESC,
it is recommended not to activate
SPORT mode on surfaces with
medium- and low-grip (e.g., wet,
snow, dirt, etc..) with ESC system
active (
(ESC OFF) button not
pressed).
NOTE:
• When in “ESC off” mode, the TCS
functionality of ESC is deactivated
(except for the limited slip feature
described in the TCS paragraph of
this chapter). All other stability
features of ESC function regularly.
• To improve the vehicle's traction
when driving with snow chains, or
when starting off in deep snow,
sand, or gravel, it may be desirable
to switch to the “ESC off” mode by
pressing the
(ESC OFF) button and
remain in this operational mode no
longer than needed. Once the
situation requiring “ESC off” mode is overcome, turn the ESC on again by
pressing the
(ESC OFF) button.
This may also be performed while in
motion.
Anti-Lock Braking System (ABS)
and Electronic Brake-force
Distribution (EBD) The Anti-Lock Braking 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.
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 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.Driving
5
249

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.
Pumping brakes makes the stopping
distance longer. Just press firmly on
your brake pedal when you need to
slow down or stop. Do not pump
brakes.
Traction Control System (TCS) The current device is an integral part
of the ESC system. It operates
automatically by reducing the power
transmitted by the engine in case of
slipping, loss of grip on wet floor
(aquaplaning), acceleration on slippery
snow-covered or frozen surfaces, etc.
Activating under slip conditions
different control systems: • if slippage affects both drive wheels,
it reduces the power transmitted by
the engine;
• if slippage only affects one drive
wheel, it brakes the slipping wheel
automatically.
Brake Assist System (BAS) This system completes the ABS system
by optimizing the vehicle braking
capacity during emergency brake
maneuvers. The system detects an
emergency braking situation by
sensing the rate and amount of brake
application and then applies optimum
pressure to the brakes in order to help
reduce braking distances.
The quick brake coupling is optimal for
BAS performances. In order to fully
exploit the system, apply continuous
brake pedal pressure during the entire
vehicle stop sequence. Do not reduce
brake pedal pressure earlier than
required. Once the brake pedal is
released, the BAS is deactivated.
Brake Throttle Override (BTO) To complete the range of systems that
assist braking, the vehicle is equipped
with BTO, which is designed to stop
the vehicle even when it is during
acceleration. If the brake pedal is
depressed together with the accelerator, the system does not
consider as “conflict” the sequence
“brake-first-then-accelerator” of pedal
application and it will not engage the
BTO. When the system recognizes that
the accelerator pedal is stuck pressed
and the sequence “accelerator-first-
then-brake-pressed” (this sequence is
recognized as a “conflict”), the engine
power should be automatically
reduced and, if the driver continues to
depress the accelerator and the brake
pedal, the system can make the vehicle
come to a complete stop.
Additionally, if the brake pedal is
released when the accelerator is still
stuck pressed, the corresponding
engine torque increases gradually to a
safe value.
During this event, the ETC light
indicator will illuminate. The system
exits from this strategy when the
accelerator pedal is completely
released.
Hill Start Assist (HSA) The HSA system is designed to assist
the driver when starting a vehicle
uphill. HSA will maintain the level of
brake pressure applied for a short
period of time also after releasing the
brake pedal.Driving
5
250

If the driver does not apply the
throttle during this short period of
time, the system will release brake
pressure and the vehicle will start
sloping down. The system will release
brake pressure proportionally to the
amount of throttle/torque applied as
the vehicle starts to move in the
chosen direction.
HSA Activation Criteria
The following criteria must be met in
order for HSA to activate:
• vehicle is stationary;
• gear selection matches vehicle uphill
direction (i.e., vehicle facing uphill is
in forward gear; vehicle backing
uphill is in reverse gear).
HSA will work in R (Reverse) and all
forward gears when the activation
criteria have been met.
The system will not activate if the
transmission is placed in N (Neutral) or
P (Park). Using the Brakes CAUTION!
To obtain a good performance by
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
and by a message on the
instrument cluster.
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.
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 miles driven on the road.
The 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
of miles.
During this break-in period, the
slightly reduced braking ability must
be compensated for by pressing the
brake pedal harder. This appliesDriving
5
251

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, the
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. The
automatic or manual activation of the
parking brake will ensure vehicle
braking.
Brake overheating could also cause
“squeals” and “vibration”. 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
miles/kilometers of operation. This
should be considered as a normal part of the break-in and not interpreted as
an indication of malfunction.
Specific Requirements
Avoid exceeding 5000 rpm for the first
620 mi trip (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°).
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.Driving

CAUTION!
• Under normal conditions, all red
warning lights on the instrument
cluster display should be off. When
they come on, this indicates 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.
Onboard Diagnostic System Your vehicle is equipped with a
sophisticated onboard diagnostic
system. This system monitors the
performance of the emissions, engine,
and automatic transmission control
systems. When these systems are
operating properly, your vehicle will
provide excellent performance and
fuel economy, as well as engine
emissions well within current local
regulations of various countries.
If any of these systems require service,
the system will turn on the
Malfunction Indicator Light (MIL).
It will also store diagnostic codes and
other information, which your Authorized Maserati Dealer will use to
service your vehicle. Although the
vehicle will still be driveable and not
need towing, contact an Authorized
Maserati Dealer for service as soon as
possible.
CAUTION!
• Prolonged driving with the
Malfunction Indicator Light
(MIL) on could cause further damage
to the emissions control system. It
could also affect fuel economy and
drivability. The vehicle must be
serviced before any emissions tests
can be performed.
•Ifthe
Malfunction Indicator
Light (MIL) is flashing while the
engine is running, severe catalytic
converter damage and power loss will soon occur. Immediate service is
required at an Authorized Maserati
Dealer .
• After the problem has been solved,
the Authorized Maserati Dealer
personnel will perform specific tests
for a complete check of the system
and, if necessary, road tests.Driving

Electronic Cruise Control The electronic Cruise Control (CC)
enables the driver to maintain the
desired vehicle speed without pressing
the accelerator pedal, reducing driving
fatigue on highways, especially long
trips, as the set speed is automatically
maintained. A firm press on the
accelerator pedal or the braking pedal
will temporarily deactivate the cruise
control function.
CAUTION!
The device can only be switched on at
speeds exceeding 18 mph (30 km/h)
and it switches off automatically when
the brake pedal or the accelerator
pedal is pressed.
WARNING!
The Cruise Control function must only
be activated when traffic and the
route permit a constant speed to be
maintained safely for a sufficiently
long distance. Controls The electronic Cruise Control controls
are located on the left side of the
steering wheel.
Control configuration depends on
which driver assist systems are installed
to the vehicle.
In the standard configuration there is
a specific button to enable and disable
the CC.
In the optional configuration, there is
no specific button to enable and
disable the CC, since the driver uses
the ACC control buttons. Control buttons have the following
functions:
Standard Configuration
ON/OFF button to
engage/disengage CC
system.
Optional Configuration
Press ACC Gap button and
hold it down for 2 seconds
to enable the CC system.
