warning light MASERATI QUATTROPORTE 2019 Repair Manual

CAUTION!
• Under normal conditions, all red
warning lights on the instrument
cluster display should be off. When
they come on, this indicates 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.
Onboard Diagnostic System Your vehicle is equipped with a
sophisticated onboard diagnostic
system. This system monitors the
performance of the emissions, engine,
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 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.
•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
for a complete check of the system
and, if necessary, road tests.Driving

WARNING!
Never leave the electronic Cruise
Control system on when not in use.
You could accidentally set the system
or cause it to go faster than you want.
Always leave the system off when you
are not using it.
Speed Range of Use Speed mph (km/h)
Minimum 18 (30)
Engaged/activated 18 (30)
Maximum 130 (210)
Setting Desired Speed Turn on the CC function. When the
vehicle has reached the desired speed
(in the example: 60 mph), push
downward the multifunction switch
(SET -) and release.
The
green light below the desired
speed will illuminate on the
instrument cluster display. Release the accelerator and the vehicle
will operate at the selected speed.
NOTE:
The vehicle should be traveling at a
steady speed and on level ground
before pushing the switch downward.
Pressing the
“ON/OFF” button or
the ACC Gap button for 2 seconds (in
the Optional Configuration) or moving
the ignition switch in OFF position
erases the set speed memory.
Changing Speed Setting Pushing the multifunction switch
upward (RES +) or downward (SET -)
once, or by holding it down, will
enable to increase or decrease the set
speed by one unit (1 mph or 1 km/h). If
the car is equipped with ADAS
Systems, the single press of the
multifunction switch will increase or decrease the set speed of 1 mph or
1 km/h; a continuous pressure of the
same will increase or decrease the set
speed of 5 mph or 10 km/h.
Release the switch when the desired
speed is reached, and the new set
speed will be visualized below the
green light.
Each subsequent tap of the
multifunction switch will increase or
decrease the speed by 1 mph or
1 km/h.
Temporary Deactivation A soft tap on the brake pedal, pressing
the multifunction switch (CANC), or
normal brake pressure while slowing
the vehicle will temporarily deactivate
the CC without erasing the set speed
memory. The
white light with
below the set speed will appear on the
display.Driving

Driver Override If the driver presses the accelerator
pedal while the CC is on, such as to
overtake another vehicle, and exceeds
the set speed limit, the system will
temporarily deactivate the CC. During
the event, the speed indication below
the
green light will be blinking.
When the accelerator pedal is
released, the vehicle will return to the
set speed and the
green light with
below the set speed with steady light
will be displayed.
Resume Speed To resume a previously set speed, push
upward the multifunction switch (RES
+) and release. The
green light
with below the set speed will
illuminate on the instrument cluster.
Resume can be used at any speed
above 18 mph (30 km/h). 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 is a standard equipment while
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 aDriving
5
257

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

Push the ON/OFF button a second time
and release to turn the system off. A
pop-up message is displayed for 2
seconds to indicate that ACC was
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 the 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.
(Continued)Driving

(Continued)
• 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 the
accelerator pedal (see “ACC
Operation Before and During Stop”
in this chapter).
• The ACC system maintains set speed
when driving up hill and down hill.
However, a slight speed change on
moderate hills is normal. In addition,
downshifting may occur while
climbing uphill or descending
downhill. This is normal operation
and necessary to maintain set speed.
When driving uphill and downhill,
the ACC system will cancel if the
braking temperature exceeds normal
range.
Temporary Deactivation A soft tap on the brake pedal, pushing
the multifunction control (CANC), or normal brake pressure while slowing
the vehicle will temporarily deactivate
the ACC without erasing the set speed
memory. The
white light will appear
on the display with below the set
speed.
Conditions for Disabling and
Deactivation Besides the cases specified in the
previous paragraph, the following
conditions will disable the system:
• Anti-Lock Brake (ABS) kicks in.
• Transmission lever is not in D (Drive).
• The Electronic Stability Control and
the Traction Control System (ESC/TCS)
activate.
• Vehicle parking brake is operated.
• The driver safety belt is unbuckled at
low speed.
• The driver door is ajar at low speed.
• The driver disabled the ESC using the
(ESC OFF) button on central
console.
• The road is too steep both uphill and
downhill at low speed.
The system is deactivated and set
speed is deleted from system memory,
if the ACC ON/OFF button is pressed or
if ignition device is turned to OFF .Resuming Speed If a speed setting is stored in system
memory, press the multifunction
control (RES +) up and take foot off
the accelerator pedal. The last set
speed will be displayed.
WARNING!
The resume function should be used
only when road and traffic conditions
allow it. Resuming a too high or too
low speed for current traffic and road
conditions could cause a harsh vehicle
acceleration or deceleration which
could increase the risk of collisions
and death or serious injury.
Setting the ACC Gap The specified ACC gap can be set by
varying the distance setting among the
four possible options identified by the
number of horizontal bars:
• Maximum (longest) distance: 4 bars.
• Long distance: 3 bars (default
distance).
• Medium distance: 2 bars.
• Short distance: 1 bar.
Using this distance setting and the
vehicle speed, ACC calculates and sets
the gap to the vehicle ahead.Driving
5
262

If system does not detect the presence
of any vehicles ahead, only the bars
referred to set distance will be
displayed.
When system detects the presence of a
vehicle ahead, it is displayed in front
of the bars (see example in the figure).
To increase or decrease the number of
bars, corresponding to the gap from vehicle ahead, press and release the
distance setting button.
Each press and release of the button
changes the gap starting from 3 bars
(default distance) and moving in a
sequential way towards the minimum
distance: 3 → 2 → 1 → 4 → 3 → 2 → 1 → 4 and so
on.
If there is no vehicle ahead, the
vehicle will maintain the set speed. If a
slower moving vehicle is detected in
the same lane, the system displays the
target vehicle icon before the bars.
From that moment, the system adjusts
the vehicle speed automatically to
maintain the distance setting,
regardless of the set speed.
The vehicle will then maintain the set
distance until:
• The vehicle ahead accelerates to a
speed above the set speed. • The vehicle ahead moves out of the
lane or view of the sensor.
• The distance setting is changed.
• The driver disables the system.
The maximum braking applied by ACC
is limited; however, the driver can
always apply the brakes manually, if
necessary. Obviously, any time the ACC
system automatically operates the
brakes, the brake lights will turn on as
if the driver was braking.
A Proximity Warning on display will
alert the driver if ACC predicts that its
maximum braking level is not
sufficient to maintain the set distance.
If this occurs, a visual alert will flash
on the display and a chime will sound
while ACC continues to apply its
maximum braking capacity.Driver Assist Page

system will compensate and provide
additional brake force as required.
When the system determines a
collision with the vehicle in front of
you is no longer probable, the
warning messages will be deactivated.
NOTE:
• Bad weather conditions, like heavy
rain, snow, etc., can lead to reduced
system performance. Under these
conditions relevant objects will not
be detected or detected late by the
system.
• FCW is designed to react in specific
situations in typical traffic scenarios
with objects in the same lane driving
in the same direction, but under
certain conditions it can also react
on stationary objects in the same
lane. It is not designed to react to
oncoming traffic or crossing traffic.
• The FCW alerts may be triggered to
objects other than vehicles such as
guard rails or sign posts based on
the course prediction. This is
expected and is a part of normal
FCW activation and functionality.
• It is unsafe to test the FCW system.
To prevent such misuse of the
system, after four Active Braking
events within a key cycle, the Active
Braking portion of FCW will be deactivated until the next key cycle.
The limit of four events applies to
the brake actuation too.
• FCW will automatically deactivated
when
(ESC OFF) button is pressed
(LED light up).
WARNING!
• Forward Collision Warning (FCW) is
not intended to avoid a collision on
its own, nor can FCW detect every
type of potential collision. The
driver has the responsibility to avoid
a collision by controlling the vehicle
via braking and steering. Failure to
follow this warning could lead to
serious injury or death. The driver is
always in charge to safely drive and
to avoid critical situations, and not
rely on the support of the FCW
system. Driver has to keep in mind
that the system and therefore its
intervention is always subject to the
prevailing physical limits.
• Forward Collision Warning (FCW) is
not intended either to warn or to
apply any brake aid/brake
intervention in case of collisions
with pedestrians (if not equipped with PEB sub-system), bicycles and
not licensable vehicles in general.
Speed Range of Use Speed mph (km/h)
Minimum 0 (0)
Engaged/activated 1.12 (1.8)
Maximum 155 (250)
When the speed is outside the
specified limits, the system
automatically disables without turning
on the corresponding warning light
on the instrument cluster.
FCW Status The driver can adjust FCW sensitivity
or enable/disable the brake actuation
with the other emergency brakings by
touching "Controls" soft-key on MTC+
display. The current setting is indicated
beside to the "Forward Collision
Warning" soft-key. If you want to
change the setting, touch the soft-key
on the side to enter FCW page.Driving

269

Setting options are described in the
following paragraph.
When FCW status for some reason
changes to off, the corresponding
amber warning light on instrument
cluster will light on.
This warning light informs the driver
that FCW is disabled. This warning
light will light even when the
activation of another driver assistance
feature or drive mode (example:
(ESC OFF)) disables the FCW. NOTE:
The FCW system setting is kept in
memory from one key cycle to the
next.
Changing FCW Sensitivity and
Active Braking The default status of FCW Sensitivity is
the “Medium” setting. When the
active braking function (“Forward
Collision Warning Active Braking”)
setting is on, the system warns you of
a possible collision with the vehicle in
front of you when you are farther
away and it applies limited braking.
This gives you the most reaction time
to help avoid a possible collision.
Changing the sensitivity status to the
“Near” setting, allows the system to
warn you of a possible collision with
the vehicle in front of you when you
are much closer. This setting provides
less reaction time than the “Far”
sensitivity setting, which allows for a
more dynamic driving experience.
“Medium” is the intermediate status
between the two described above. NOTE:
• The default values shall appear at
every new ignition cycle: Sensitivity =
“Medium” and Active Braking = on.
• FCW may not react to irrelevant
objects such as objects not in the
path of the car, stationary objects
that are far away, oncoming traffic,
on cross traffic vehicles, or leading
vehicles with the same or higher rate
of speed.
• The active braking (autonomous
braking/braking aid) will not be
provided in case of potential collision
with static object such as guard rails,
walls, etc..).
• FCW will be disabled like ACC (refer
to chapter “Adaptive Cruise Control -
ACC” in this section.
Changing the active braking status to
“Off” prevents the system fromDriving
5
270

providing limited autonomous braking
or additional brake support if the
driver is not braking adequately in the
event of a potential frontal collision.
In this state the system disables the
brake jerk.
Limited Operation and Service
Warning The messages indicating on display the
limited functionality or service at an
Authorized Maserati Dealer required
are the same as for the ACC system.
For further details, refer to “Adaptive
Cruise Control – ACC” in this section.
NOTE:
• The adjustment of the sensor could
be affected by strong shocks or light
collisions. This could affect the
system by reducing the systems
performance or could increase the
false positive rate. The adjustment of
the radar system has to be proved or
a new adjustment has to be
performed by an Authorized
Maserati Dealer .
• The radar system requires specific
feature to detect objects. The
detection could be disturbed/
reduced by environment influences,
for example by electrical field or the
object itself. Object with small radar reflection properties could not be
detected or detected late.
Radar Device - Regulatory
Information The “Regulatory Information” for all
the radio frequency and radar devices
can be consulted by accessing the
“Services” section on the website
www.maserati.com.
Lane Keeping Assist - LKA
(optional, with ACC only) This system was designed especially
for highway or freeway driving, to
reduce the risk that the vehicle, under
particular circumstances, accidentally
departs from the lane in use. When
this happens, graphic instructions on
instrument cluster display together
with steering torque application and
steering wheel vibration (depending
on the distance to the line) warn the
driver that the vehicle is going out of
the lane initiates a steering maneuver
to try to prevent the lane exit.
To detect lane lines, the system uses
the forward-facing camera behind the
rear-view mirror, which is the same
one used also by the lighting system
to manage the automatic high beams.
The logic core is in the front radar.
LKA system remembers the condition
it was in before turning off the
vehicle.
