2016 Alfa Romeo Giulia ABS

AST (Alfa™ Steering Torque)SYSTEM
53)
The AST function uses the integration of
the ESC system with the electric power
steering to increase the safety level of
the whole vehicle.
In critical situations (braking on surfaces
with different grip conditions), through
the AST function the ESC system
controls the steering to implement an
additional torque contribution on the
steering wheel, to suggest the most
correct manoeuvre to the driver.
The coordinated action of the brakes and
steering increases the sensation of
safety and control of the vehicle.
ATV (Alfa™ Active Torque Vectoring)
SYSTEM
The dynamic drive control is used to optimize
and balance the drive torque between the
wheels of the same axis. The ATV system
improves the grip in turns, sending more drive
torque to the external wheel.
Given that, in a turn, the external wheels
of the car travel more than the internal
ones and therefore turn faster, sending a
higher thrust to the external rear wheel
allows for the car to be more stable and
to not suffer a phenomenon called
"understeer". Understeer occurs when,
during a turn, a car tends to widen the set
trajectory, in this situation the lateral
acceleration the car is subjected tobecomes higher that the grip of the tyres,
which are unable to maintain the car in
the trajectory set by the driver through
the steering angle determined by turning
the steering wheel.
WARNING
30)For maximum efficiency of the braking
system, a bedding-in period of about 500 km
(310 miles) is required: during this period it
is advisable to avoid sharp, repeated and
prolonged braking.
31)If the ABS intervenes, this indicates that
the grip of the tyres on the road is nearing its
limit: you must slow down to a speed
compatible with the available grip.
32)
The ABS cannot overrule the natural laws
of physics, and cannot increase the grip
available according to the condition of the road.
33)The ABS cannot prevent accidents, including
those due to excessive speed on corners, driving
on low-grip surfaces or aquaplaning.
34)The capability of the ABS must never be
tested irresponsibly and dangerously, in
such a way as to compromise personal
safety and the safety of others.
35)
For the correct operation of the ABS, the
tyres must of necessity be the same make and
type on all wheels, in perfect condition and, above
all, of the prescribed type and dimensions.
36)There may be a brief delay in shifting to
AWD mode after a tyre slipping event.
37)When a DTC system failure symbol
appears, the driver must be aware of the
different driving reaction and therefore
reduce the speed. The symbol
warns the
driver not to drive in areas that require
four-wheel drive or on snow-covered roads.38)The ESC system cannot alter the natural
laws of physics, and cannot increase grip,
which depends on the condition of the road.
39)The ESC system cannot prevent
accidents, including those due to excessive
speed on corners, driving on low-grip
surfaces or aquaplaning.
40)The capability of the ESC system must
never be tested irresponsibly and
dangerously, in such a way as to compromise
personal safety and the safety of others.
41)For the correct operation of the ESC
system, the tyres must necessarily be of the
same make and type on all wheels, in perfect
condition and, above all, of the prescribed
type and size.
42)ESC performance features must not
induce the driver to take unnecessary or
unwarranted risks. Your driving style must
always be suited to the road conditions,
visibility and traffic. The driver is, in any
case, responsible for safe driving.
43)For the correct operation of the TC
system, the tyres must of necessity be the
same make and type on all wheels, in perfect
condition and, above all, of the prescribed
type and dimensions.
44)TC performance features must not
induce the driver to take unnecessary or
unwarranted risks. Your driving style must
always be suited to the road conditions,
visibility and traffic. The driver is, in any
case, responsible for safe driving.
45)The TC system cannot overrule the
natural laws of physics, and cannot increase
the grip available according to the condition
of the road.
46)The TC system cannot prevent
accidents, including those due to excessive
speed on corners, driving on low-grip
surfaces or aquaplaning.

SAFETY

Radar indication not available
If conditions are such that the radar
cannot detect obstacles correctly, the
system is deactivated and a dedicated
message appears on the display. This
generally occurs in the event of poor
visibility, such as when it is snowing or
raining heavily.
The system can also be temporarily
dimmed due to obstructions such as mud,
dirt or ice on the bumper. In such cases, a
dedicated message will be shown on the
display and the system will be
deactivated. This message can
sometimes appear in conditions of high
reflectivity (e.g. tunnels with reflective
tiles or ice or snow). When the conditions
limiting the system functions end, this
will go back to normal and complete
operation.
In certain particular cases, this dedicated
message could be displayed when the
radar is not detecting any vehicles or
objects within its view range.
If atmospheric conditions are not the real
reason behind this message, check if the
sensor is dirty. It could be necessary to
clean or remove any obstructions in the
area shown in fig. 68.
If the message appears often, even in the
absence of atmospheric conditions such
as snow, rain, mud or other obstructions,contact an Alfa Romeo Dealership for a
sensor alignment check.
In the absence of visible obstructions,
cleaning the radar surface, by manually
removing the decorative cover trim,
could be required. Have this operation
performed at an Alfa Romeo Dealership.
IMPORTANT It is recommended that you
do not install devices, accessories or
aerodynamic attachments in front of the
sensor or darken it in any way, as this can
compromise the correct functioning of
the system.
Frontal collision alarm with active
braking
(where provided)
If this function is selected, the brakes are
operated to reduce the speed of the
vehicle in the event of potential frontal
impact.
This function applies an additional
braking pressure if the braking pressure
applied by the driver does not suffice to
prevent potential frontal impact.
The function is active with speed above
4 mph (7 km/h).
Driving in special conditions
In certain driving conditions, such as, for
example:
driving close to a bend;
the vehicle ahead is leaving a
roundabout;
vehicles with small dimensions and/or
not aligned in the driving lane;
lane change by other vehicles;
vehicles travelling at right angles to
the vehicle.
system intervention might be
unexpected or delayed. The driver must
therefore be very careful, keeping
control of the vehicle to drive in complete
safety.
IMPORTANT In particularly complex
traffic conditions, the driver can
deactivate the system manually through
the Connect system.
Driving close to a bend
When entering or leaving a wide bend, the
system may detect a vehicle that is in
front of you, but that is not driving in the
same lane fig. 70. In cases such as these,
the system may intervene.
7006016S0005EM
73

"TPMS check" message with some
dashes (– –) instead of the pressure
values.
From the following ignition cycle, the
TPMS will not emit any acoustic signal
and the display will not show the
message "TPMS check", but the dashes
will be still displayed instead of the
pressure value.
WARNING
54)The system is an aid for vehicle driving,
it DOES NOT warn the driver about incoming
vehicles outside of the detection areas. The
driver must always maintain a sufficient
level of attention to the traffic and road
conditions and for controlling the trajectory
of the vehicle.
55)The Forward Collision Warning (FCW)
system is automatically deactivated when
RACE mode is selected.
56)The system is an aid for the driver, who
must always pay full attention while driving.
The responsibility always rests with the
driver, who must take into account the
traffic conditions in order to drive in
complete safety. The driver must always
maintain a safe distance from the vehicle in
front.
57)If the driver depresses the brake pedal
fully or carries out a fast steering during
system operation, the automatic braking
function may stop (e.g. to allow a possible
manoeuvre to avoid the obstacle).58)The system intervenes on vehicles
travelling in the same lane. People, animals
and things (e.g. pushchairs) are not taken
into consideration.
59)If the car must be placed on a roller
bench for maintenance interventions or if it
is washed in an automatic roller washing
tunnel with an obstacle in the front part (e.g.
another car, a wall or another obstacle), the
system may detect its presence and
activate. In this case the system must be
deactivated through the settings of the
Connect system.
60)The presence of the TPMS does not
permit the driver to neglect regular checks
of the tyre pressure, including for the spare
tyre, and correct maintenance: the system is
not used to signalling a possible tyre fault.
61)Tyre pressure must be checked with
tyres rested and cold. Should it become
necessary for whatever reason to check
pressure with warm tyres, do not reduce
pressure even though it is higher than the
prescribed value. Repeat the check when the
tyres are cold.
62)Should one or more wheels be fitted
without sensors, the system will no longer be
available and a warning message will be
shown on the display, until wheels with
sensors are fitted again.
63)The TPMS cannot indicate sudden tyre
pressure drops (e.g. if a tyre bursts). In this
case, stop the vehicle, braking with caution
and avoiding abrupt steering.
64)Changes in outside temperature may
cause tyre pressures to vary. The system
may temporarily indicate insufficient
pressure. In this case, check the tyre
pressure when cold and, if necessary,
restore the inflation values.65)Replacing standard tyres with winter
tyres and vice versa requires TPMS system
adjustment that must only be performed by
Alfa Romeo Dealerships.
66)When a tyre is removed, it is advisable
to replace the rubber valve seal as well:
contact an Alfa Romeo Dealership. The
fitting/removal of the tyres and/or rims
require special care. To avoid damaging or
fitting the sensors incorrectly, tyre and/or
rim fitting/removal operations should only
be carried out by specialised staff. Contact
an Alfa Romeo Dealership.IMPORTANT
19)The system may have limited or absent
operation due to weather conditions such as:
heavy rain, hail, thick fog, heavy snow.
20)The section of the bumper before the
sensor must not be covered with adhesives,
auxiliary headlights or any other object.
21)System intervention might be
unexpected or delayed when other vehicles
transport loads projecting from the side,
above or from the rear, with respect to the
normal size of the vehicle.
22)Operation can be adversely affected by
any structural change made to the vehicle,
such as a modification to the front geometry,
tyre change, or a heavier load than the
standard load of the vehicle.
23)Incorrect repairs made on the front part
of the vehicle (e.g. bumper, chassis) may alter
the position of the radar sensor, and
adversely affect its operation. Go to an Alfa
Romeo Dealership for any operation of this
type.
77

31)When the engine stopped never leave
the ignition device in the ON position to
prevent useless current draw from draining
the battery.
32)Warning light
will flash after starting
or during prolonged cranking to indicate a
fault with the glow plug heating system. If
the engine starts, the vehicle can be regularly
used, but an Alfa Romeo Dealership must be
contacted as soon as possible.
33)A quick burst on the accelerator before
turning off the engine serves absolutely no
practical purpose; it wastes fuel and is
damaging for the engine.
ELECTRIC PARKING BRAKE
The vehicle is equipped with electric
parking brake to guarantee better use
and optimal performance compared to a
manually operated parking brake.
The electric parking brake features a
switch, located on the central tunnel
fig. 101, a motor with caliper for each
rear wheel and an electronic control
module.
The electric parking brake can be
engaged in two ways:
manually, by pulling the switch on the
central tunnel;
automaticallyin "Safe Hold" or "Auto
Park Brake" conditions.
IMPORTANT Normally, the electric
parking brake is engaged automatically
when the engine is stopped. This function
can be deactivated/activated on theConnect system by selecting the
following items in sequence on the main
menu: "Settings", "Driver assistance" and
"Automatic parking brake".
IMPORTANT Always engage the electric
parking brake before leaving the vehicle.
IMPORTANT In addition to parking the
vehicle with the parking brake always
engaged, the wheel steered, chocks or
stones positioned in front of the wheels
(when on a steep slope), you must always
engage:
Manual transmission:
Engage 1stgear if the car is parked
uphill or reverse gear if the car is parked
downhill.
Automatic transmission:
engage P (Park) mode.
IMPORTANT Should the vehicle battery
be faulty, to unlock the electric parking
brake the battery must be replaced.
Engaging the parking brake manually
103) 104) 105)
Briefly pull the switch located on the
central tunnel to manually engage the
electric parking brake when the vehicle is
stationary.
Noise may be heard from the rear of the
vehicle when engaging the electric
parking brake.

presence of: ice, snow, mud, thick paint,
on the surface of the sensor;
the sensor may detect a non-existent
obstacle ("echo interference") due to
mechanical interference, for example
when washing the vehicle, in rain (strong
wind), hail;
the signals sent by the sensor can also
be altered by the presence of ultrasonic
systems (e.g. pneumatic brake systems
of trucks or pneumatic drills) near the
vehicle;
parking assistance system
performance can also be influenced by
the position of the sensors, for example
due to a change in the ride setting
(caused by wear to the shock absorbers,
suspension), or by changing tyres,
overloading the vehicle or carrying out
specific tuning operations that require
the vehicle to be lowered;
the presence of a tow hook without
trailer, which may interfere with the
correct operation of the parking sensors.
Before using the Park Sensors system, it
is recommended to remove the
removable tow hook ball assembly and
the relevant attachment from the vehicle
when the latter is not used for towing
operations. Failure to comply with this
prescription may cause personal injuries
or damage to vehicles or obstacles since,
when the continuous acoustic signal is
emitted, the tow hook ball is already in aposition that is much closer to the
obstacle than the rear bumper. If you
wish to leave the tow hook fitted without
towing a trailer, it is advisable to contact
an Alfa Romeo Dealership for the Park
Sensors system update operations
because the tow hook could be detected
as an obstacle by the central sensors.
the presence of adhesives on the
sensors. Therefore, take care not to place
adhesives on the sensors.
WARNING
114)Parking and other potentially
dangerous manoeuvres are, however,
always the driver’s responsibility. When
performing these operations, always make
sure that there are no other people
(especially children) or animals on the route
you want to take. The parking sensors are an
aid for the driver, but the driver must never
allow their attention to lapse during
potentially dangerous manoeuvres, even
those executed at low speeds.
IMPORTANT
38)The sensors must be clean of mud, dirt,
snow or ice in order for the system to
operate correctly. Be careful not to scratch
or damage the sensors while cleaning them.
Avoid using dry, rough or hard cloths. The
sensors should be washed using clean water
with the addition of car shampoo if
necessary. When using special washing
equipment such as high pressure jets or
steam cleaning, clean the sensors very
quickly keeping the jet more than 10 cm
away.
39)Have interventions on the bumper in the
area of the sensors carried out only by an
Alfa Romeo Dealership. Interventions on the
bumper that are not carried out properly
may compromise the operation of the
parking sensors.
40)Only have the bumpers repainted or any
retouches to the paintwork in the area of the
sensors carried out by an Alfa Romeo
Dealership. Incorrect paint application could
affect the operation of the parking sensors.

LANE DEPARTURE WARNING
(LDW) SYSTEM
DESCRIPTION
41) 42) 43) 44) 45) 46)
The Lane Departure Warning system
makes use of a camera located on the
windscreen to detect the lane limits and
calculate the position of the vehicle
within such limits, in order to make sure
that it remains inside the lane.
When one or both lane limits are
detected and the vehicle passes over one
without the driver's say-so (direction
indicator not turned on), the system
emits an acoustic signal.
If the vehicle continues to go beyond the
line of the lane without any intervention
from the driver, the surpassed line will
light up on the display (left or right) to
urge the driver to bring the vehicle back
into the limits of the lane.
SYSTEM ACTIVATION/DEACTIVATION
The system is activated/deactivated by
pressing the button, fig. 113
When the engine is started the system is
always activated.Activation conditions
Once switched on, the system becomes
active only if the following conditions are
met:
the vehicle speed is above 45 mph
(70 km/h);
the lane limit lines are visible at least
on one side;
there are suitable visibility conditions;
the road is straight or with wide radius
bends;
a suitable distance is kept from the
vehicle in front;
the direction indicator (for leaving the
lane) is not active.
IMPORTANT
41)Projecting loads on the roof of the
vehicle may interfere with the correct
operation of the camera. Before starting
make sure the load is correctly positioned, in
order not to cover the camera operating
range.
42)If the windscreen must be replaced due
to scratches, chipping or breakage, contact
exclusively an Alfa Romeo Dealership. Do not
replace the windscreen on your own, risk of
malfunction! It is advisable to replace the
windscreen if it is damaged in the area of the
camera.
43)Do not tamper with nor operate on the
camera. Do not close the openings in the
aesthetic cover located under the interior
rear view mirror. In the event of a failure of
the camera, contact an Alfa Romeo
Dealership.
44)Do not cover the operating range of the
camera with stickers or other objects. Also
pay attention to other objects on the bonnet
(e.g. a layer of snow) and make sure they do
not interfere with the camera
45)The camera may have limited or absent
operation due to weather conditions such as:
heavy rain, hail, thick fog, heavy snow,
formation of ice layers on the windscreen.

STARTING AND DRIVING

46)Camera operation may also be
compromised by the presence of dust,
condensation, dirt or ice on the windscreen,
by traffic conditions (e.g. vehicles that are
driving not aligned with yours, vehicle driving
in a transverse or opposite way on the same
lane, bend with a small radius of curvature),
by road surface conditions and by driving
conditions (e.g. off-road driving). Make sure
the windscreen is always clean. Use specific
detergents and clean cloths to avoid
scratching the windscreen. The camera
operation may also be limited or absent in
some driving, traffic and road surface
conditions.REAR BACK-UP CAMERA /
