The set speed for HDC is selectable by
the driver, and can be adjusted by
using the pedal unit or the
multifunction control on steering
wheel, which is the same used to set
the Cruise Control (see “Electronic
Cruise Control” or “Adaptive Cruise
Control - ACC” in this section).
• If the driver brakes, the speed goes
below the default value: when s/he
releases the brake pedal, the speed
goes back to 3 mph (4 km/h).
• If the driver accelerates without
exceeding the maximum limit value
of 18 mph (30 km/h), when s/he
releases the accelerator pedal HDC
will set to the speed reached by
vehicle in that moment. The set value
appears under the
green light on
the display.
Or: • Push down (SET -) multifunction
switch to decrease the speed up to
1.8 mph (3 km/h) : pressing the brake
pedal up to default speed of 5 mph

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.

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.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.Driving

Using Electronic Cruise Control
on Hills The transmission may be downshifted
on hills to maintain the vehicle set
speed. The CC system maintains set
speed up and down hills. A slight
speed change on moderate hills is
normal. On steep slopes it is
recommended to drive without CC.
WARNING!
Electronic Cruise Control can be
dangerous where the system cannot
maintain a constant speed. Do not use
electronic Cruise Control in heavy
traffic or on winding, icy,
snow-covered or slippery roads. Adaptive Cruise Control -
ACC (optional) ADAS Equipments The Adaptive Cruise Control (ACC) is
part of ADAS equipments together
with:
• Lane Keeping Assist (LKA)
• Active Blind Spot Assist (ABSA)
• Forward Collision Warning (FCW)
• Highway Assist (HAS)
• Traffic Sign Assist (TSA).
FCW, HAS and TSA are separate
functions that may not be present in
the ADAS equipment. For more details
see “Forward Collision Warning -
FCW”, “Highway Assist - HAS" and
"Traffic Sign Assist - TSA" in this
section.
NOTE:
LKA and ABSA are described in the
relevant chapters of this section.
ACC Preview The Adaptive Cruise Control (ACC)
further increases the drive comfort
ensured by the Cruise Control when
driving on highways and freeways.
Always consider that ACC is not a safety system and is not designed to
prevent accidents.
The ACC allows driver to keep Cruise
Control active in limited or moderate
traffic conditions with no need to
constantly restore the Cruise Control.
The ACC uses a radar sensor, located
on the front grille behind the trident,
and the forward-facing camera behind
the internal rear-view mirror to detect
the presence of a vehicle ahead at a
close distance and moving in the same
direction.
This vehicle, in this chapter, will be
indicated as "target vehicle" or
"vehicle ahead".
NOTE:
• If the sensor detects no vehicle
ahead, the ACC system will maintain
set steady speed.
• If the ACC sensor detects a vehicleDriving
5
286

ahead, the ACC system automatically
kicks in by slightly accelerating or
braking (to avoid exceeding the
initially set speed) so that the vehicle
keeps present distance, trying to
adapt to the speed of the detected
vehicle ahead.
WARNING!
• The Adaptive Cruise Control (ACC) is
designed to increase vehicle driving
comfort. It must not be considered
as a means of replacing the required
attention of the driver. The driver is
always required to drive carefully.
The driver is always required to pay
utmost attention to driving
conditions (road, traffic, weather)
and style (speed, distance from
sensed vehicle ahead, brake use).
Driver has the full responsibility of
the vehicle therefore his attention is
crucial to keeping vehicle control, in
particular when approaching curves
and situations with heavy traffic.
Failure to follow these warnings can
result in a collision and death or
serious personal injury
• In some driving scenarios, the ACC
could have detection problems. In
such cases, the ACC could kick in late or unexpectedly. The driver must be
careful since his/her intervention
could be necessary.
• It is always the driver’s responsibility
to obey speed limits and to keep
minimum legal distance to the
preceding vehicle.
• ACC system can decelerate only with
limited braking, it cannot execute
emergency braking.
The ACC system:
•
Does not activate/react in the
presence of pedestrians, bicycles,
incoming traffic from opposite
direction and steady objects such as
a vehicle stuck in a traffic jam.
• Is meant for the use on highways
and well-built roads, not for city
traffic or mountain roads.
• May not have enough time to react
and/or decelerate sufficiently on
vehicles when lane is changed too
quickly or the relative speed is too
high. In such cases the driver has to
react appropriately and without any
acoustic/visual warning.
• Cannot consider road, traffic and
weather conditions and might prove
limited when visibility is poor.
• Does not always fully recognize
complex driving conditions and this could cause an incorrect assessment
of the required safety distance.
It is recommended to disable the ACC
system in the following instances:
• When driving in the fog, heavy rain,
heavy snow, slush, heavy traffic and
similar complex situations such as
highway construction zones.
• When entering a junction lane or a
slip road to leave the highway; when
driving on narrow, icy, snowy,
slippery roads, or on uphill and
downhill roads.
• The system is designed and calibrate
for car with no trailer.
• When circumstances do not allow to
drive safely at constant speed.

disabled.
WARNING!
Leaving the Adaptive Cruise Control
(ACC) system on when not in use is
dangerous. You could accidentally
activate the system or cause it to go
faster than you want. Always leave
the system off when you are not using
it.
Setting the Speed When the vehicle reaches the required
speed, press down and release the
multifunction control (SET -). The
display will show set speed
corresponding to vehicle current one.
Speed value will be indicated below
the
green symbol and above the distance bars, in the center of the
display.
Remove foot from accelerator pedal
and vehicle will continue at set speed.
Driver Override If driver accelerates beyond the set
speed or faster than the car would do
with ACC engaged, the set speed
below the
green light will blink and
the time gap bars will vanish to
indicate that in this condition the
system cannot control the distance
between vehicle and sensed vehicle
ahead. Vehicle speed will be
determined only by the accelerator
pedal position.
Changing Speed Setting Once speed is set, driver can increase
or decrease it by respectively pressing
multifunction control up (RES +) or down (SET -). Speed can be increased
or decreased in two ways:
• Pressing control once, set speed will
increase or decrease by one unit
corresponding to 1 mph (1 km/h).
• Hold the control to increase or
decrease set speed by 5 mph
(10 km/h) at a time.
NOTE:
• When pressing the multifunction
control up (RES +) or down (SET -),
the new set speed will be the current
speed of the vehicle.
• When using (SET -) control to
decelerate, if the engine braking
power does not slow down the
vehicle sufficiently to reach the set
speed, the brake system will
automatically slow down the vehicle.
• The ACC system applies the brake
down to a full stop when following a
target vehicle. If an ACC host vehicle
follows a target vehicle to a
standstill, after a two or three second
delay, the system will not be able to
resume driving the car
autonomously. At this point it is
necessary for the driver to manually
reengage the system by either using
the multifunction control (press SET-
or RES+) or by pressing theDriving
