2019 MASERATI GHIBLI wheel torque

Active Blind Spot Assist -
ABSA (optional, with ACC
only) ABSA system is only available on
vehicles equipped with ACC system
and represents an addition to the BSA
previously described (see chapter
"Blind Spot Assist - BSA" of this
section).
ABSA adds to the BSA the possibility in
certain circumstances to avoid and or
mitigate side collisions with vehicles
proceeding in the adjacent lanes by
changing the car's direction in order
to try to keep it inside the
detected/estimated lane. A steering
wheel vibration is used as further
feedback to warn the driver that the
lane change is not safe.
The main logic core is the front radar,
whereas the sense inputs are the
radars on the rear bumper fascia used
for sensing the presence of vehicle in
the blind spot areas and the forward
facing camera placed behind the
internal rear-view mirror that instead
is used for lane detection and
estimation.
ABSA is designed to help the driver to
avoid mitigate a collision. Torque and
vibration application is however available in the 37 - 112 mph (60 -
180 km/h) speed interval. All the speed
thresholds related to the BSA remain
still valid, since ABSA as mentioned is
BSA extension.
ABSA is intended as a “hands-on”
function meaning that the driver is
required to stay engaged in the
driving all the time with his/her hands
on the steering wheel, in case hands
are not on the steering wheel for a
certain time there cannot be any
steering torque application vibration
included.
System Availability ABSA is designed for an attentive
driver therefore the system is available
only when his/her hands are on the
steering wheel or with hands off for a
very limited amount of time. When
the system is enabled, it will trigger
cluster warning in case at least one
hand is not detected on the steering
wheel.
The torque application as well as the
vibration are suppressed/inhibited in
case of: high driver torque in the
steering wheel, high lateral
acceleration, hands not on the
steering wheel detected for more than
a certain time. Highly dynamic behaviours, driving on
the lane boundary, off course will
prevent the function from working.
FCW braking and stability system
interventions (ESC, ABS) will also
prevent the system from operating.
Changing lane results in system
inhibition for a certain time.
In addition the road must respect
some characteristics such as minimum-
maximum width, lane clearly defined
by two lane boundaries and only in
limited case for a limited time at least
one.
NOTE:
• In case of wet road or raining
conditions the function could be
disabled by the system in order to
minimize the risks.
• With lane boundaries it is mainly
referred to painted lines,
nevertheless the system in good
conditions might properly recognise
as valid lane boundaries also other
types (for example road edges,
curbs, etc..).Driving

• ABSA “Strength": it tunes the
steering torque value to have a
stronger or weaker directional
correction/deviation.
Blind Spot Assist in "Visual & Haptic"
Mode
When the system is on and configured
“Visual & Haptic” then the ABSA is
enabled and to the conventional
visual warnings is added the steering
torque and vibration.
When operating in this mode, the
system will provide a visual alert in the
appropriate outside rear-view mirror
when it detects a vehicle or an object
in the detection areas monitored by its
sensors. In case of turn indicator
activation on the appropriate side, the
system will react with a torque on the
steering wheel to try to prevent the
lane change and therefore to
avoid/mitigate the collision. The
torque on the steering is applied
when the car is very close to the lane
boundary as a further feedback to
warn the driver of the unsafe
maneuver.
NOTE:
• The steering torque is not supplied if
the system is not able to estimate a
lane and if the turn indicator from
the appropriate side is not inserted. • The presence of the hands on the
steering wheel is detected by a logic
combination of a capacitive sensor
installed in the steering wheel and
the measured applied torque at the
steering column. This leads to a
more robust hands detection.
WARNING!
• Risk of accident despite steering
torque application of Active Blind
Spot Assist (ABSA).
• A course-correcting steering torque
application cannot always prevent a
collision.
• The driver is always required to
steer, brake or accelerate themself,
especially if ABSA warns or makes a
course correcting steer intervention.
• Always maintain a safe distance at
the sides.
• Steering torque application may be
interrupted at any time by counter
steering by the driver.
RCP - Rear Cross Path
Operation RCP operation is the same as described
in chapter "Blind Spot Assist - BSA". When ABSA is turned off from MTC+
"Controls" page, there will be no
visual or audible alerts from RCP
subsystem.
When ABSA is turned on with any
setting,RCP subsystem shall respond
with both visual and audible alerts
when a detected vehicle or object is
present. Whenever an audible alert is
requested, the radio (if on) is also
muted.
Right/left turn/hazard signal status is
ignored; the RCP status always
requests the chime.
System Temporarily
Unavailable The blind spot system will become
temporarily unavailable and the
instrument cluster display will show
the message “Blind Spot Alert
Temporarily Unavailable” when the
vehicle enters a radio quite zone
(example the areas around radio
telescopes).
The warning light on the outside
rear-view mirrors will be lit up and
stay lit until the vehicle exits the zone.
System Fault The ABSA system cannot properly
operate either due to a fault of its
components, or because the area onDriving

• Lateral accelerations exceeds the
limits.
NOTE:
• When HAS cancels, the symbol
will turn red then grey.
• The presence of the hands on the
steering wheel is detected by a logic
combination of a capacitive sensor
installed in the steering wheel and
the measured applied torque at the
steering column. This leads to a
more robust hands detection.
System Limitations HAS is unable to guide the vehicle
when the following conditions occur.
• Lane markings are not clear or
visibility is poor (i.e. heavy rain,
snow, fog, etc.).
• Obstructed, covered or damaged
forward-facing camera or sensor.
• When driving on hills or sharp
curves.
• When approaching toll booths.
• When the highway entrance or exit
is wider than 20 ft (6 meters).
• Bright light (ex. direct sunlight or
glare) facing the forward camera. WARNING!
Many unforeseen conditions can occur
that can affect the performance of
Highway Assist (HAS). Always keep
this in mind and drive attentively. It is
the drivers responsibility to keep
control of the vehicle at all times.
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.Traffic Sign Assist – TSA
(optional) TSA detects traffic signs through the
use of a forward-facing digital camera
mounted on windshield, behind the
rear-view mirror. TSA assists the driver
by displaying on the instrument
cluster detected speed limits and
traffic signs with a restriction
indicated by an additional sign (e.g. in
snow conditions). TSA also uses the
data of the navigation system, in
order to provide information to the
driver in all cases in which the camera
is not able to detect the traffic signs
that are present on the road where
the car is travelling.
Some examples of these are: due to
low visibility, light reflection, damaged
traffic signs, traffic signs in wrong
position like rotated or fallen poles.
NOTE:
• Overtaking restriction signs are not
displayed by the TSA system.
• TSA provides a visual warning to the
driver when he/she unintentionally
reaches the maximum speed limit
allowed or when it exceeds the set
“Sensitivity” value.

WARNING!
• The spare wheel is narrower than
standard wheels and must only be
used to travel the distance required
to reach a service station, where the
punctured tire can be repaired or
replaced.
• Do not exceed a maximum speed of
50 mph (80 km/h) when using the
compact spare wheel; when this
limit is exceeded, the stability, road
holding and braking of the vehicle
will be compromised. Avoid
accelerating to full speed, heavy
braking and fast cornering.
• The compact spare wheel must be
inflated to the recommended tire
pressure (see “Tire Inflation
Pressure” in section “Features and
Specifications”). • For safety reasons, it is absolutely
forbidden to drive with more than
one compact spare wheel fitted on
the vehicle.
• Snow chains cannot be fitted on the
compact spare wheel.
• The spare wheel can travel a
maximum of 1,800 mi (3.000 km).
To Refit the Standard Wheel with
Repair
ed or Replaced Tire
• Following the procedure and the
caution described above, raise the
vehicle and remove the compact
spare wheel reusing the supplied
wrench with adapter, suitably
extended.
• Fit the standard wheel with repaired
or replaced tire.
• Tighten the original bolts on the
wheel.
• Lower the vehicle and remove the
jack.
• Fully tighten the bolts, alternately
tightening diametrically opposite. WARNING!
Observe the tightening torque for the
bolts securing the wheels (72 ± 7 lbf·ft
/ 98 ± 10 Nm). Check the correct
tightening torque as soon possible
contacting an Authorized Maserati
Dealer.
• Reassemble the center cover (if
equipped)
on the wheel rim.
Once finished:
• completely deflate the compact
spare wheel by pressing on the valve
with the overhang of the valve cap;
• place the compact spare wheel and
tool container in the trunk;
• fix everything in place with the

ignition switch is in the OFF position. If
this is not observed, when the ESC is
active, the ECU will store a
malfunction and the relative warning
light
will illuminate on the
instrument cluster display. This
requires the intervention of an
Authorized Maserati Dealer to reset
the system.
Towing an AWD Vehicle
WARNING!
Single axle towing or use of a tow
dolly is not allowed since it will
severely damage components of an
AWD vehicle.
WARNING!
Use of a tow dolly on front wheels is
strictly forbidden since front wheels
may still receive a residual amount of
torque and disengage the vehicle from
the tow dolly and affect safety of
both rescuers and other road users. Use the Tow Hook of the Tool
Kit CAUTION!
The tow hook should only be used for
towing the car on flat roads. Do not
use the tow hook to remove the car
that is stuck on off road stretches.
The tow hook is also used to tow the
vehicle
on the
platform of a tow truck.
The tow hook is contained in the tool
kit (see “Tool Kit” in this section) and
must be screwed in its seat accessible
behind the front grille, right-hand
side, after removing the protective
cap.
• Carefully clean the threaded seat
before screwing the hook.
• Screw the tow hook into its seat for
at least 11 turns. NOTE:
Maximum work angle of towing cable:
15°.
