Left-hand Multifunction Lever
The multifunction lever on the left side
of the steering column controls the
operation of the turn signals,
headlight beam selection and
overtaking lights.
This multifunction lever also controls
the Cruise Control. See chapter "Cruise
Control" in section "Driving" for
further information.
Turn Signals
Move the left-hand multifunction lever
all the way up or down until the stop
trigger.
The left or right arrow indicator on
respectively the speedometer and
tachometer instrument cluster, flashes
to show proper operation of the front
and rear turn signal lights.To activate lane change function, tap
the lever up or down once, without
moving beyond the detent. The turn
signals (right or left) will flash three
times then automatically turn off.
This function is useful when
overtaking or changing lanes.NOTE:
If either light remains on and does not
flash, or flashes at a fast rate, check for
a defective outside light bulb. If an
indicator on instrument cluster fails
while moving the lever, then the
indicator bulb is probably defective.
High Beams and Flashing
To switch on the high beams with the
light switch in headlamp
or
“AUTO” position, shift the left-hand
multifunction lever onward.
A related
blue telltale will
illuminate on the tachometer.
By pulling the lever backward (toward
the steering wheel) you switch off the
high beams and switch on the low
beams.

(e.g., rain, snow, ice, sand, etc.) it is
advisable not to activate SPORT
mode, even with the ESC enabled.ICE Drive Mode Indicator
This indicator illuminates
when the low grip function is
active.
Fuel Economy Indicator
While driving, the system will
indicate that you should shift
gears in order to optimize fuel
consumption when the
required speed is reached.
The recommended gearshift indicator
will only work when the transmission
is set to manual sequential operation.

mode is active.
MANUAL Drive Mode Indicator
This indicator illuminates

system (with digital maps where
available), communication and
information features within a single
system.
The MTC+ System features an audio
system which is acoustically optimized
for this specific vehicle.
WARNING!
The navigation system assists the
driver while driving, providing advice
and suggestions, by voice guidance
and graphic information, for the best
route to reach the set destination. The
suggestions provided by the
navigation system do not relieve the
driver from full responsibility for the
maneuvers made through traffic while
driving, or from compliance with road
regulations and other provisions
regarding road traffic. The person

ESC System Operations
In order to prevent unstable driving
conditions, the ESC system may request
the transmission system to deactivate
gearshifting. The system handles this
request depending on the gear
engaged and on the rpm, and decides
whether to accept it or not.
Driving with Cruise Control
With the Cruise Control function
activated, the transmission system
selects such settings as to provide
enhanced comfort and fuel-economy.
MC Start Strategy
(for MC version only)
With the aim of optimizing standing
starts for performance driving (only
recommended for use in areas closed
to traffic and in accordance with the
Highway Code), the automatic
transmission system is equipped with
quick start strategy.
This strategy is activated when the
following conditions occur
simultaneously:
• AUTO and SPORT modes active;
•
ESC mode off;
• brake pedal depressed.In these conditions, the driver has the
possibility to accelerate and, keeping
the brake pedal depressed, keep the
vehicle standing until reaching an
engine speed between 2300 an 2500
rpm. Then, upon releasing the brake
pedal, have the best standing start
performance.
WARNING!
This strategy must only be used on
vehicles in areas closed to traffic, in
accordance with the Highway Code
and only by skilled drivers.
Transmission Malfunction and
Overheating Conditions
Transmission Failure
Transmission function is electronically
monitored to detect abnormal
conditions. If a condition that could
result in transmission damage is
detected, Transmission Limp Home
Mode will be activated. In this
situation, the transmission may
operate only in certain gears, or may
not shift at all.
CAUTION!
In these conditions, we recommendedthat you stop the vehicle and turn off
the engine for at least one minute.
When restarting the engine, the
self-diagnosis system may cancel the
malfunction, which will in any case be
recorded by the ECU.
A message and thewarning light
in the instrument cluster will inform
the driver about the transmission
failure.
In failure conditions, the transmission
shift lever can however be shifted to R
(Reverse), N (Neutral) and D (Drive)
position.
When shifting to D (Drive) position,
only a few gears will be available,
depending on the malfunction found.
CAUTION!
If a transmission failure is signaled,
take your vehicle to the nearest
Authorized Maserati Dealeras soon as
possible to have the problem
corrected.
If the failure is signaled when the
engine is started, it means that the
transmission ECU detected a fault
when the vehicle was last used. Also in
this case, take your vehicle to the
nearest Center of theAuthorized

exhaust, do not idle the engine except
as necessary, service your vehicle in a
well-ventilated area and wear gloves
or wash your hands frequently when
servicing your vehicle. For more

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
