2019 MASERATI QUATTROPORTE ECU

Starting with a Cold Engine
Start-off slowly, avoiding sudden
acceleration and rev the engine up at
low medium speeds. High-
performance driving should be
avoided until the engine temperature
reaches 149-158°F (65-70°C).
Engine Turn-Off • With the shift lever in P (Park), D
(Drive) or R (Reverse) positions (see
“Automatic Transmission” in this
section) and vehicle standstill, press
and release the START/STOP button
to switch off the engine. A burst on
the accelerator pedal before turning
off the engine has no purpose and
increases fuel consumption.
• If the shift lever is in N (Neutral) and
the START/STOP button is pressed
once, the instrument cluster will
display a “Vehicle Not in Park”
message and the engine will remain
running.
WARNING!
Never leave a vehicle out of the P
(Park) position, as it could move. NOTE:
If
the ignition switch is left in the ACC
or RUN (engine not running) position
and the transmission is in P (Park), the
system will automatically time out
after 30 minutes of inactivity and the
ignition will switch to OFF position.
Engine Turn Off when in Automatic
Start&Stop
When the engine has been turned off
by the Start&Stop system, press and
release the START/STOP button. The
ignition switch will return to the OFF
position and the vehicle is off.
“Panic Stop” Strategy In panic conditions, if driver stops
engine in any non-standard manner
while driving at a speed over 2 mph
(3 km/h), the “Panic Stop” strategy can
manage the situation by checking
gearchange condition upon engine
cutting, driver’s action on brakes, road
condition (flat or slope) so as to set
gearchange to the most suitable
condition.
The “Panic Stop” strategy considers
that the driver should stop the engine
by pressing the ignition switch at least
3 times or holding it depressed for at
least 2 seconds.Automatic Start&Stop
System The Maserati Start&Stop system allows
the engine to automatically switch off
when the vehicle stops and to restart
when the driver intends to drive. This
feature can reduce fuel consumption
up to 6% according to different drive
conditions. During the “Stop
(AutoStop)” phase the ignition is still
on and all security features are
available.
In order for the Start&Stop to activate,
the vehicle must be stationary and the
brake pedal adequately pressed.
NOTE:
If the brake pedal is not sufficiently
pressed the Start&Stop may not
function even if the vehicle is stopped.
When the Start&Stop switches off the
engine, the related light
illuminates on the instrument
cluster.
As soon as the brake pedal is released,
the engine turns on.
While the vehicle is stopped, the
transmission can be placed in P (Park)
pressing the “P” button on the shift
lever.Driving

In this way the system moves the
transmission in P (Park) position.
Automatic Transmission Range P (Park)
Use this position to park the vehicle.
The transmission can be shifted from
“P” position only with the brake pedal
and the unlock button pressed: then
move the shift lever. To move the shift
lever from “P” position to any other
position, the engine must be switched
on. The engine can be regularly
started in P (Park) range. Never
attempt to use P (Park) while the
vehicle is in motion. When parking on
a level surface, you may press the “P”
button first, and then apply the
electronic parking brake by pulling the
trigger upwards. The Instrument cluster will display the
related indicator light
and the
message for 5 seconds.
When parking on a hill, apply the
parking brake before pressing the “P”
button.
For enhanced security, turn the front
wheels toward the kerb on a downhill
and away from the kerb on an uphill
grade. WARNING!
• Never use the P (Park) mode as a
substitute for the electric parking
brake. Always apply the parking
brake fully when parked to prevent
vehicle movement and possible
injury or damage.
• Make sure the transmission is in P
(Park) before leaving the vehicle.
CAUTION!
• DO NOT race the engine when
shifting from P (Park) or N (Neutral)
into another gear range, as this can
damage the drivetrain.
• The following indicators should be
used to ensure that you have
engaged the shift lever into the “P”
position:
– when shifting into P (Park), push
the “P” button on the shift lever.
– with the brake pedal released,
verify that “P” position is
illuminated on the shift lever and
in the instrument cluster display.Driving

NOTE:
The gearshift indicator will only work
when the transmission is set in M +/-
(Manual) mode.
Transmission Malfunction and
Overheating Conditions Transmission Emergency Control
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. In some situations, the
transmission system may not
re-engage if the engine is turned off
and restarted.
A message in the instrument cluster
will inform the driver about the more
serious transmission conditions, and
indicate what actions may be
necessary.
Transmission Oil Overtemperature
If the transmission oil temperature
exceeds the operating limit, the red
warning light
illuminates on the
instrument cluster. In this case, slow down until
temperature returns to normal level
(the light will turn off).
If this is not sufficient, we recommend
to stop the vehicle, shift the lever to
position P (Park) or N (Neutral) and
keep the engine idle until the
temperature red warning light
turns off and the message
disappears from the display. Resume
driving without demanding high
engine performance. If the red
warning light
and the related
message turns on again, it is advisable
to stop the vehicle, turn off the engine
and wait for the engine/transmission
assembly to fully cool down.
If the instrument cluster message
indicates that the transmission may
not re-engage after engine shutdown,
perform the following procedure
preferably at an Authorized Maserati
Dealer . In the event of a momentary problem,
the transmission can be reset to regain
all forward gears by performing the
following steps.
• Stop the vehicle.
• Shift the transmission into P (Park), if
possible.
• Turn the engine off.
• Wait approximately 30 seconds.
• Restart the engine.
• Shift the transmission into D (Drive)
and then into the desired gear
range. If the problem is no longer
detected, the transmission will return
to normal operation.
NOTE:
Even if the transmission can be reset,
we recommend that you visit an
Authorized Maserati Dealer at your
earliest possible convenience, which
has diagnostic equipment to
determine if the problem could recur.

can be deactivated/reactivated by
selecting the menu item “Vehicle
settings” through the switch on the
right side of the steering wheel (refer
to “Instrument Cluster” in section
“Dashboard Instruments and
Controls”.)
Press and release the switch toward
the arrow (
) to select “Electric Park
Brake”.
Press and release the switch once
again toward the arrow ( )to
visualize the options connected to this
function. • Auto Apply On (recommended
setting);
• Auto Apply Off.
Scroll with the switch toward the
arrow
or through the
programmable options.
Press and release the switch toward
the arrow (
) to set the selected
option. A check mark will remain next
to the previously-selected item until a
new selection is made. “Setting Saved” Selection notification
appears as a popup for 2 seconds then
the display will show again the
modified function.
In order to disable the automatic
operation follow the same procedures
and select the other option.
CAUTION!
• Under certain conditions when the
battery voltage is low, the electric
automatic parking brake system may
temporarily be deactivated for safety
reasons. Therefore, typically upon
starting the engine, when the
battery voltage drops, a message
may temporarily be displayed,
indicating that automatic operation
is temporarily disabled.

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 off” 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

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 vehicle 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 the 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 and 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 thisDriving

Driving Conditions Before the Trip Check the following at regular
intervals and always before long trips:
• tire pressure and condition;
• levels of fluids and lubricants;
• conditions of the windshield wiper
blades;
• clean the glass on the external light
and all other glass surfaces;
• proper operation of the indicator
lights and of the external lights.
CAUTION!
It is however advisable to perform
these checks at least every 600 mi
(1000 km) and always following the
maintenance schedule reported in
section “Maintenance and Care”.
Before you drive:
•
adjust seat position, steering wheel,
adjustable pedals (if equipped with)
and rearview mirrors in order to
have the best driving position;
• ensure that nothing (mat covers,
etc.) is obstructing the pedals
movement; • carefully arrange and secure any
objects in the trunk, to prevent them
from moving forward in case of
sudden stops;
• avoid heavy meals before a trip. A
light snack helps keep your reflexes
sharp. In particular, avoid drinking
alcohol.
WARNING!
Passengers must only travel seated in
the vehicle seats, with the seat belts
fastened. Always check that the driver
and all passengers have the seat belts
correctly fastened.
Safe Driving Although the vehicle is equipped with
active and passive safety devices, the
driver's conduct is always a decisive
factor for road safety.
Some simple rules for traveling safely
in different conditions are listed
below. Some of them will probably
already sound familiar but, in any
case, it would be useful to read them
carefully.
Driving at Night
The main guidelines to follow when
driving at night are set out below. • Drive carefully. Night conditions
demand more focus and attention.
• Reduce your speed, especially on
roads with no streetlights.
• Stop at early signs of drowsiness.
Continuing to drive would be a risk
for yourself and for others. Have a
rest before continuing your trip.
• Keep the vehicle at a greater
distance from vehicles in front of
you than you would during the day:
it is difficult to assess the speed of
other vehicles when you only see the
lights.
• Use the high beams only outside of
densely-populated areas and when
you are sure that they will not
disturb other drivers.
• When another vehicle is
approaching, switch from high
beams (if on) to low beams.
• Keep lights and headlights clean.
• Outside of densely-populated areas,
beware of animals crossing the road.
Driving in the Rain
Rain and wet roads are dangerous. On
a wet road all maneuvers are more
difficult since wheel grip on the road
is significantly reduced. This means
that braking distances increase
considerably and road grip decreases.Driving

Inflation Pressure” in section
“Features and Specifications”) and
screw the cap on the compact spare
wheel valve.
CAUTION!
• In order to obtain a more accurate
reading, the compressor should be
switched off when checking the tire
pressure of the compact spare wheel
on the pressure gauge.
• Do not run the compressor for more
than 20 minutes: there is a risk it
could overheat. Also, prolonged
power absorption may discharge the
battery, subsequently preventing the
engine from starting.
• The compressor has been designed
exclusively to inflate compact spare wheels; do not use it to inflate air
mattresses, floatation devices, etc.
• Fit the adapter on the wrench.
Extend
the wrench as shown, then
loosen by approximately one turn,
the five bolts on the wheel to be
changed.
• Place the jack near the wheel to be
changed as illustrated.
• Make sure that the head of the jack
is correctly inserted in one of the
slots beneath the rocker panel.
WARNING!
• The jack should be used on level firm
ground wherever possible.
• It is recommended that the wheels
of the vehicle be chocked, and that
no person should remain in a vehicle that is being jacked.
• If the vehicle has been stopped on a
slope or an uneven surface, place
chocks or other suitable items in
front of or behind the wheels to
stop the vehicle from moving.
• Never start or run the engine with
the vehicle on a jack.
• No person should place any portion
of their body under a vehicle that is
supported by a jack.
WARNING!
• Never position yourself under a
jacked vehicle.
• The lifted vehicle may fall and
damage the vehicle's body if the jack
is not positioned correctly.
• Never use the jack to carry out
maintenance or repairs under the
vehicle.
• Turn the jack lever until the wheel is
raised a few
centimeters off the
ground.
• Completely unscrew the five bolts
and remove the wheel. In case a
wheel security stud bolt is installed, it
can only be removed by using theIn an Emergency
