“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.
Vehicle condition Action of the driver
The system puts the
transmission in P
(Park) position.• Engine running and speed lower than
1.8 mph (3 km/h).
• Transmission in any position other P
(Park).
• Driver safety belt unlocked.
• Driver door opened.
• Brake pedal pressed. The driver releases the brake pedal to
get out of the vehicle.
Warnings Warnings
• Slow continuous chime.
• The condition of the vehicle not in P
(Park) position will be signaled by a
message on the display. • Fast chime.

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);
• ROM (Roll-Over Mitigation);
• TSM (Trailer Sway Mitigation);
• HDC (Hill Descent Control).
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 sand, or
gravel. The current mode disables the
TCS portion of the ESC and raises theDriving
5
273
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: to 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 of f” 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
274
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.
• The ABS installed to this vehicle
does not control trailer braking
system. Pay utmost attention when
driving on slippery ground since the
trailer traction might get poorer.
• Do not modify the vehicle braking
system to control the trailer brakes.
The hydraulic system controlling
vehicle braking must remain
independent from trailer braking
system. 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 will 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 increase gradually to a
safe value.
During this event, the ETC light
indicator will illuminate. The systemDriving
5
275
exits from this strategy when the
accelerator pedal is completely
unstuck.
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.
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).
Roll-Over Mitigation (ROM) This system anticipates the potential
for wheel lift by monitoring the
driver's steering wheel input and the
speed of the vehicle. When ROM
determines that the rate of change of
the steering wheel angle and vehicle's
speed are sufficient to potentially
cause wheel lift, it then applies the
appropriate brake and may also
reduce engine power to lessen the
chance that wheel lift will occur.
ROM will only intervene during very
severe or evasive driving maneuvers.
ROM can only reduce the chance of
wheel lift occurring during severe or
evasive driving maneuvers. It cannot
prevent wheel lift due to other factors,
such as road and off-road conditions,
leaving the roadway, or striking
objects or other vehicles.
WARNING!
Many factors, such as vehicle loading,
road and off-road conditions, and
driving conditions, influence the
chance that wheel lift or rollover may occur. ROM cannot prevent all wheel
lift or roll-overs, especially those that
involve leaving the roadway or
striking objects or other vehicles. The
capabilities of a ROM-equipped
vehicle must never be exploited in a
reckless or dangerous manner, which
could jeopardize the user’s safety or
the safety of others.
Trailer Sway Mitigation (TSM) TSM uses sensors in the vehicle to
recognize an excessively swaying
trailer and will take the appropriate
actions to attempt to stop the sway.
The system may reduce engine power
and apply the brake of the
appropriate wheel(s) to counteract the
sway of the trailer. TSM will become
active automatically once an
excessively swaying trailer is
recognized.
TSM cannot stop all trailers from
swaying. Always use caution when
towing a trailer and follow the trailer
tongue weight recommendations.
Refer to “Trailer Towing” in this
section for further information. When
TSM is functioning, the “ESC
Activation/Malfunction Indicator
Light” will flash (see “Instrument
Cluster” in section “DashboardDriving
5
276
Instruments and Controls”), the
engine power may be reduced and
you may feel the brakes being applied
to individual wheels to attempt to
stop the trailer from swaying.
TSM is disabled when the ESC system is
partially deactivated (button
pressed, LED on).
WARNING!
If TSM activates while driving, slow
the vehicle down, stop at the nearest
safe location, and adjust the trailer
load to eliminate trailer sway.
Hill Descent Control (HDC) HDC maintains vehicle speed while
descending hills during various driving
situations, by actively controlling the
brakes.
HDC is part of the ESC system and has
three possible states:
• Off: feature is not enabled and will
not activate.
• Enabled: feature is enabled and
ready but activation conditions are
not met, or driver is actively
overriding with brake or throttle
application. • Active: feature is enabled and
actively controlling vehicle speed.
Enabling and Activating the HDC
HDC is enabled by pressing the HDC
switch on LH side of steering wheel.
NOTE:
The figures only show the Standard
Configuration. The following conditions must also be
met to enable HDC:
• Maximum activation speed: 18 mph
(30 km/h).
• Parking brake is released.
• Driver door is closed.
HDC enabling is indicated by the
white light with below 3 dashes on
instrument cluster display coming
steady on. The light remains white
while the driver operates the pedal
unit to change the speed, or when
driving on a flat stretch of road
between two descents, or when the
descent is over.
Failed enabling is indicated by a
message on display.
Once enabled, when driving the
system automatically activates HDC.
When the vehicle exceeds 2.5 mph
(4 km/h) and a defined threshold of
slope, the light
turns green and the
current speed appears below it until
the default speed value set to 5 mph
(8 km/h). Therefore, the vehicle speed
is increased or decreased until it
reaches the default value.Standard Configuration
Optional Configuration Driving
5
277
• HDC will be deactivated but remain
available when driver pushes the
accelerator steadily, without
exceeding 18 mph (30 km/h). A
pop-up message and the
green
light will stay on.
• When the vehicle speed exceeds
18 mph (30 km/h) but is lower than
31 mph (50 km/h) this function turns
to stand-by mode, the
light with
below the set speed turns white. In
this case, to reset the function it is
necessary to push up (RES +)
multifunction switch.
• While, if speed exceeds 31 mph
(50 km/h), or when driving beyond
18 mph (30 km/h) for over 70
seconds, system will immediately
disable the feature and the
light
will turn off. Brake Overheating with HDC
The icon on instrument cluster display
and the LED on steering wheel button
will flash when HDC deactivates due
to overheated brakes. The flashing
will stop and HDC will activate again
once the brakes have cooled
sufficiently.
WARNING!
• HDC is only intended to assist the
driver in controlling vehicle speed
when descending hills. The driver
must remain attentive to the driving
conditions and is responsible for
maintaining a safe vehicle speed.
• Prolonged use of the system might
overheat the brakes. In case of
brake overheating, the HDC, if
active, will be progressively
deactivated after warning the driver
(switch-off of LED on button);
feature can be reactivated only after
brake temperature will have
decreased sufficiently. Distance that
can be traveled depends on brake
temperature, load and vehicle
speed.
• The performance of a vehicle
equipped with HDC must never be
exploited in a reckless or dangerous manner that could jeopardize the
driver’s safety or the safety of
others.

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 “bed 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 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, 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 “vibrations”.Driving
