• 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)

(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 sufficientto 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.

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,
Driving
5
183

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 the 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
on the test bench for a complete
check of the system and, if necessary,
also road tests, even on long
distances.
In addition, the system is equipped
with
a diagnostics connector that,
when interfaced with suitable
instruments, makes it possible to read
the error codes stored in the ECU,
together with a set of specific
parameters for engine operation diagnostics cycle, on compliance with
CARB, EPA OBDII rules.
CAUTION!
• Once the engine is started, the
Malfunction Indicator Light (MIL)
will remain on for approximately 18
seconds before turning off. This is a
normal condition and part of the
operating strategy.
• When the key in the ignition switch is turned to MAR (ON)position if the
Malfunction Indicator Light (MIL)
does not illuminate or if it
illuminates while driving, contact
your local Authorized Maserati
Dealer as soon as possible.

Position of the Diagnostic Connector
The
diagnostic connector is positioned
underneath the dashboard, next to
the hood opening lever. It can be
accessed without removing any cover.
Cruise Control (CC)
The 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 19 mph (30 km/h)
and it switches off automatically when
the brake pedal is pressed or when a
speed of 125 mph (200 km/h) is
exceeded.
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 controls of the CC are located on
the multifunction lever, on the left
side of the steering wheel.
• The innermost ON/OFF switch has two positions:
OFF: the CC is deactivated;
ON: the CC is active. When the CC is
activated, the
green warning
light on the display illuminates
together with the message “Cruise
control on”.
• The rotating section in the middle of the left multifunction lever is used to
store the vehicle speed, to keep it
constant or to increase or decrease
the speed stored. Turn the rotating
section to position "+" to save the
speed reached or to increase the
speed stored. Turn the rotating
section to position "–" to decrease
Driving
5
185

the speed stored. Every time rotating
section is reset, the speed is increased
or decrease by approx. 0.6 mph (1
Km/h). Keep the rotating section
turned to vary the speed
continuously. When a new speed is
reached, it will automatically remain
constant.
• Button "RCL" at end of left multifunction lever is used to resume
the speed stored.
NOTE:
• When the key in the ignition switch
is turned to STOP (OFF)position or
ON/OFF switch is in the "OFF"
position, the speed stored is erased
and the system deactivated.
• The CC must be deactivated when
not in use.
WARNING!
Leaving the Cruise Control system on
when not in use is dangerous. You
could accidentally set the system or
cause it to go faster than you want.
Always leave the CC off when you are
not using it. Storing a Speed
T

urn the ON/OFF switch to "ON" and
reach the desired speed driving
normally. Turn the rotating section in
the middle of the left multifunction
lever to "+" for at least 3 seconds and
then release it.
The vehicle speed is stored and the
accelerator pedal can be released.
The vehicle will proceed at the
constant speed stored until the brake
pedal is pressed.
If necessary, (for example, to pass
another vehicle), you can accelerate by
simply pressing the accelerator pedal.
Afterward, when you release the
accelerator pedal, the vehicle will
return to the speed previously stored.
Resuming the Speed Stored
If the CC has been deactivated after
braking, the speed previously stored
can be resumed as follows:
• gradually accelerate until you reach a speed close to that stored;
• engage the gear selected when the speed was stored (4th, 5th or 6th
gear);
• press button "RCL".
Increasing the Speed Stored
The speed stored can be increased in
two ways: • by pressing the accelerator and then
storing the new speed reached (turn
the rotating section in the middle of
the left multifunction lever for more
than 3 seconds); or
• by turning the rotating section to position "+": each impulse
transmitted by the rotating section
will cause a slight increase in speed
(about 0.6 mph/1 Km/h), whereas a
constant pressure on the same
rotating section will cause a
continuous increase in speed. When
the rotating section is released, the
new speed will be automatically
stored in the memory.
Decreasing the Speed Stored
The speed stored can be reduced in
two ways:
• by deactivating the CC, pressing the brake pedal and then storing the
new speed (turning the rotating
section to position “+” for at least 3
seconds); or
• by keeping the rotating section turned to position “-” until reaching
the new speed, which will be stored
automatically.
Resetting the Speed Stored
The speed stored is automatically
reset:
Driving

• by turning the engine off; or
• by turning ON/OFF switch to "OFF"position.
Warnings while Driving with CC
WARNING!
• When driving with CC activated, do
not shift to N (Neutral) position. It is
advisable to activate CC only when
traffic and road conditions permit
safe use of this device, that is: on
straight and dry roads, expressways
or highways, smooth flowing traffic
and smooth asphalt. Do not activate
this device when driving in town or
in heavy traffic.
• CC can only be activated at speeds
exceeding 19 mph (30 km/h).
• CC can only be activated in 4th, 5th
or 6th gear, depending upon the
vehicle speed.
• When driving downhill with the CC
activated, the vehicle may pick up
speed slightly exceeding the speed
stored, due to the change in the
engine load.
• In the event of malfunctioning or
failure of CC, turn ON/OFF switch to
"OFF" position and contact the
Authorized Maserati Dealer after having checked that the relative
fuse is in proper working order.
• ON/OFF switch can be always left at
"ON" position without damaging
the CC. In any case, it is advisable to
deactivate the CC when it is not in
use. Turn ON/OFF switch to "OFF"
position to prevent any speeds from
being unintentionally stored.
