vibrate and a graphic will display on
the instrument cluster.
WARNING!
• In case the vehicle approaches a
curve that is too tight in relation to
the current speed the system will
disengage, therefore the driver must
be prepared to take over control of
the vehicle immediately at any time.
To avoid this situation it is important
that the vehicle speed is not set
higher than the current speed limit
of the road.
• Highway Assist (HAS) is a hands-on
feature! You must keep your hands
on the steering wheel at all times.
The HAS system will disengage and
ACC will cancel if your hands are
removed from the steering wheels
for a set amount of time.
• HAS is intended for use only on
highways or limited access freeways
with a fully attentive driver. When
using HAS, hold the steering wheel
and be aware of surrounding traffic
and road conditions. Always be
prepared to immediately take over
control of the vehicle from the HAS
system. Failure to follow these instructions could result in serious
injury or death.
• The following list does not fully
represent all situations in which HAS
may not function as intended. Do
NOT solely rely on the HAS system
to control the vehicle. It is the
driver’s responsibility to stay alert
and safely control the vehicle at all
times.
• If the windshield is replaced, you
must have the forward-facing
camera remounted and aligned by
an Authorized Maserati Dealer.
Many factors can impact the
performance
of HAS
causing the
system to be unable to function as
intended. These include (but are not
limited to):
• Narrow, winding or curvy roads.
• Poor visibility (due to heavy rain,
snow, fog, etc.).
• Bright light (oncoming headlights or
direct sunlight) or shadows.
• Damage or obstruction caused by
mud, ice, snow, etc.
• A damaged or misaligned bumper.
• Interference from other equipment
that generates electromagnetic
waves. • Wet roads, roads covered or partially
covered by snow.
• Construction zones.
HAS Operation With ACC set (see “Adaptive Cruise
Crontrol – ACC” in this section), HAS
system activates by simply pressing the
button on the steering wheel.
Once the conditions are met, HAS will
engage.
CAUTION!
The Highway Assist (HAS) system may
take up to 5 seconds to engage once
all conditions are met.
The conditions for HAS to engage are
as
follows:
• HAS must be turned on or enabled.
NOTE:
In case of wet road or raining
conditions the function could be
disabled by the system in order to
minimize the risks.
• The vehicle must be on the highway
or limited access freeway.
• Adaptive Cruise Control (ACC) must
be engaged.
• Left and right visible lane lines.Driving

• Vehicle speed must be between 0 to
90 mph (0 and 145 km/h).
• No faults in the forward facing
camera, radar, EPS, or MTC+.
• Lane width between 3 to 4.6 yd (2.8
and 4.2 m).
• Turn signal not activated.
• No faults related to this system.
Speed Range of Use Speed mph (km/h)
Minimum 0 (0)
Engaged/activated
(with ACC engaged) 0 (0)
Engaged/activated
(with ACC not
engaged) 18 (30)
Maximum 90 (145)
• If set above the maximum speed,
HAS will not function after the
vehicle speed will reach the
maximum speed.
• If set below the maximum speed and
the ACC target speed is increased,
HAS will function up to the
maximum speed and then the system
will turn off automatically.
• When the ACC target speed is reduce
and speed is lower than the maximum speed, the system will start
automatically.
• If the ACC target speed is set under
the maximum speed, HAS is active
and vehicle speed increases above
the maximum speed due to slope,
HAS will continue to function.
HAS Monitoring on Instrument
Cluster HAS and the other ADAS systems
conditions can be monitored on
instrument cluster display by accessing
the “Driver Assist” page with the
buttons on the steering wheel (see
“Instrument Cluster” in section
“Dashboard Instruments and
Controls”).
The
symbol in grey indicates that
the HAS system is active, but not
engaged and is shown at the centre of
the TFT display when the “Driver
Assist” page is displayed. When exiting
the "Driver Assist" page, on TFT
display top left corner, the
grey
symbol will appear in the multiple
light of active ADAS systems. In addition to these symbols, on the
TFT top and bottom edge a coloured
glow may appear (further referred to
as "attention level colour"). Attention
level colour together with the outline
of the symbol
represent a further
indication of the system status. Driver Assist Page
Non-Driver Assist PageDriving
5
286

When exiting the “Driver Assist” page,
the attention level colour will always
be displayed until the system is
disabled by pressing the
button on
the steering wheel.
The HAS system uses sensors in the
steering wheel outer crown to detect
if the driver’s hands are on the
steering wheel. If the driver’s hands
are not detected on the steering wheel, the instrument cluster will
display a series of warnings to alert
the driver to return their hands to the
steering wheel. There will also be
audible chimes. After a set amount of
time, HAS will cancel if the driver’s
hands are not returned to the steering
wheel.
When the system does not sense the
hands on the steering wheel for a few
seconds (3 – 5 seconds) or more (up to
10 seconds), it tries to draw the
attention of the driver by showing,
even when the display is not in the
"Driver Assist" page, the
symbol
with the figure of the hands in the
centre of the display. According to
such time frames, the system will
change the attention level colour,
silence the audio in the vehicle (if it is
active) and emit audible chimes to
invite the driver to take the control of
the vehicle again. This is the only way
to reengage the system.
Hands Detection on Steering
Wheel The sensors in the steering wheel
outer crown are able to detect the
presence of the hands on the steering
wheel. In order to be able to use the HAS
system, place your hands around the
steering wheel outer crown.
NOTE:
• The sensors are not able to detect
the presence of the hands on the
steering wheel areas covered in
wood, plastic bezels or carbon
inserts (where present).
HAS is deactivated if the steering
wheel is no longer being touched.
System Statuses The active status of the HAS system is
indicated by the green attention level
colour which is maintained even if the
driver releases his/her grip from the
steering wheel up to 3 seconds.
The yellow attention level colour
appears when the driver removes
his/her hands from the steering wheelDriver Assist Page
Non-Driver Assist Page Driving

for 3 to 5 seconds and the symbol
with the figure of the hands will
occupy the whole central area of the
display.
The red attention level colour appears
when the driver releases his/her grip
from the steering wheel for 5 and up
to 10 seconds: in this case a single
audible chime is repeated until he/she will take the control of the vehicle
again.
The red attention level colour remains
even when the steering wheel is
released for more than 8 to 10
seconds. In this case, if you are
travelling at a speed above 25 mph
(40 km/h) a sequences of 3 audible
chimes will be emitted after 8 seconds and a message will inform the driver
that the HAS system has been
disengaged, instructing him/her to grip
the steering wheel again. The same
will happen after 10 seconds if you
travel at a speed below 25 mph
(40 km/h). Then the
symbol on TFT
display will become grey.
If the driver keeps his/her hands away
from the steering wheel (for more
than 8 to 10 seconds), also the ACC
system is deactivated (
white ACC
symbol on the display) and will have to
be reset. The aid of LKA system will be
disabled as well. In these cases the
display will not show the attention
level colour anymore and the vehicle
will be controlled by the driver only.
HAS Disengage To disengage HAS you can do any of
the following actions:Driver Assist Page

• Press the HAS enable button on
the steering wheel.
• Begin steering manually.
• Press brake pedal.
• Turn off ACC.
• Unbuckle the driver’s seat belt.
• Press ACC Gap button for two
seconds to enable CC system.
• Shift out of the (D) Drive gear.
• Enter an Autonomous Emergency
Braking (AEB) event (See chapter
"Forward Collision Warning - FCW"
in this section).
• Turn signal activated.
System Cancellation The HAS system will cancel (without
driver intervention) if either of the
following actions occur:
• Curve that is too tight.
• When leaving the grip of the hands
on the steering wheel.
• Vehicle exits the highway or limited
access freeway.
• Lane line markers aren’t detected by
the forward facing camera.
• Any ADAS system faults.
• ACC cancellation.
• Vehicle speed exceeds the maximum
limit. • 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.

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. • The performance of TSA depends on
the update degree of navigation
system’s maps.
Customised Settings TSA is configurable by the customer
regarding the display mode on the
instrument cluster and the warning
sensitivity.
Entering "Controls" page on MTC+
display the driver can see the current
setting beside the "Traffic Sign Assist"
soft-key.
Touching “Traffic Sign Assist” soft-key
can disable or enable the system.
Touching the soft-key on the side the
driver can change the setting.
The display of the traffic signs can be
blinking or static.
The system can be set to display the
traffic signs when the speed of the
vehicle is equal to the speed limit allowed, or when it is higher than 5 or
10 mph (5 or 10 km/h).
Signs Monitoring on
Instrument Cluster
If TSA feature is set and a sign or a
speed limit is detected, the related
icons are displayed in the upper area
of the instrument cluster beside of the
main menu number and scroll arrows.Driving
5
290

The display area is divided in three
different sectors:
1 Conditioned speed limit area.
2 Unconditioned speed limit area.
3 Overtaking restriction area.
NOTE:
Overtaking restriction sign will be
displayed only in markets where this is
allowed.
If “Blinking On” warning mode is set,
when the visual warning is provided
only the unconditioned speed limit (in
sector 2 ) will start blinking when the
vehicle speed exceeds to the detected
unconditioned speed limit (“+0 mph”
or “+0 km/h” option) or when it
exceeds the set sensitivity value
(“+5 mph” - “+5 km/h” or “+10 mph” -
“+10 km/h” options). If the vehicle
speed stays above the unconditioned speed limit for several seconds the
unconditioned speed limit sign will
stop blinking because the manoeuvre
is evaluated as intentional. If the TSA
is not able to determine any kind of
valid speed limit neither from camera
nor from digital maps the following
image will be shown in sector 2 .
Since TSA also uses the data provided
by the navigation system, it can
update the sector 2 of the display in
the following situations without
detecting traffic signs:
• When the vehicle changes road.
• Highway enter/exit.
• Urban area stored in the digital map
enter/exit.
System Limitations TSA may be impaired or may not
function in the following situations:
• If there is poor visibility, e.g. due to
insufficient illumination of the road,
if there are highly variable shade
conditions or in rain, snow or fog.
• If there is glare, e.g. from oncoming
traffic, direct sunlight or reflections
from other vehicles.
• If the windshield in the area of the
camera is dirty, or if the camera is
fogged up, damaged or covered. • If the traffic signs are hard to detect,
e.g. due to dirt or snow, or because
they are covered or because of
insufficient lighting.
• If the information in the navigation
system's digital map is incorrect or
out-of-date.
• If the signs are ambiguous, e.g.
traffic signs on construction sites or
in adjacent lanes.
• When passing buses or trucks with a
speed sticker.Driving
