• 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
nearestAuthorized 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!

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

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 nearestAuthorized
Maserati Dealerin 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 the
Driving

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 someparameters, 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
withBOS, 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

(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

sophisticated onboard diagnostic
system. This system monitors the

as necessary, service your vehicle in a
well-ventilated area and wear gloves
or wash your hands frequently when

vehicle
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 toSTOP (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
Turn 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:

before driving through the standing
water.
• Do not exceed 5 mph (8 km/h) when
driving through standing water. This
will minimize wave effects.
•
Driving through standing water may
cause damage to your vehicle
drivetrain components. After driving
through standing water, do not drive if
you are not sure about drivetrain
condition. Such damage is not covered
by the New Vehicle Warranty.
• Getting water inside your vehicle
engine can cause it to lock up and
stall out, and cause serious internal
damage to the engine. Such damage
is not covered by the New Vehicle
Warranty.
• After driving through standing
water always have the fluids (engine
oil, transmission oil, etc) checked for
contamination at anAuthorized
Maserati Dealer.
WARNING!
•Driving through standing water
limits your vehicle traction
capabilities. Do not exceed 5 mph
(8 km/h) when driving through
standing water.•Driving through standing water
limits your vehicle braking
capabilities, which increases
stopping distances. Therefore, after
driving through standing water,
drive slowly and lightly press on the
brake pedal several times to
progressively dry the brakes discs
and pads.
•Getting water inside your vehicle
engine can cause it to lock up and
stall out.
•Failure to follow these warnings
may result in injuries that are
serious or fatal to you, your
passengers, and others around you.
Pollution Control Devices
Even if the vehicle is fitted with
antipollution devices, the environment
deserves the greatest respect from
every one of us.
By following a few simple rules, the
driver can avoid damaging the
environment and very often can
reduce fuel consumption as well.
In this regard, some useful
information is listed here below;
please read it carefully.
• The first precaution is to follow the
Scheduled Service Plan scrupulously
(see “Scheduled Service Plan” in
section “Maintenance and Care”.
• The correct operation of the
antipollution devices not only helps
respect for the environment, but
also has an impact on vehicle
efficiency. Keeping these devices in
good working conditions is the first
rule for driving both ecologically
sound and economically.
• Always use unleaded fuel.
• If starting is difficult, do not make
prolonged attempts. In particular,
avoid push starts, towing or
downhill starts: these are all
maneuvers that can damage the
catalytic converters. For any
