2014 Alfa Romeo Giulietta steering wheel

ESC SYSTEM
IN BRIEF
The ESC system improves the
directional control and stability of the
car in various driving conditions.
The ESC system corrects the car’s
understeer and oversteer, distributing
the brake force on the appropriate
wheels. The torque supplied by
the engine can also be reduced in
order to maintain control of the car.
30) 31) 32) 33) 34)
The ESC system uses sensors installed
on the car to determine the trajectory
that the driver intends to follow and
compares it with the car’s effective
trajectory. When the real trajectory
deviates from the desired trajectory, the
ESC system intervenes to counter the
car’s understeer or oversteer.
❒Oversteer: occurs when the car is
turning more than it should according
to the angle of the steering wheel.
❒Understeer: occurs when the car is
turning less than it should according
to the angle of the steering wheel.The ESC system also includes the
following systems:
❒EBD
❒ABS
❒CBC
❒ASR
❒HILL HOLDER
❒HBA
❒MSR
❒DST
❒“ELECTRONIC Q2” (“E-Q2”)
❒"PRE-FILL" (RAB - Ready Alert
Brake)
SYSTEM ACTIVATION
The ESC system switches on
automatically when the engine is
started and cannot be switched off.
SYSTEM INTERVENTION
This is indicated by the flashing of the
warning light on the instrument
panel, to inform the driver that the car is
in critical stability and grip conditions.EBD SYSTEM
The EBD system is an integral part of
the ESC system and intervenes during
braking, distributing the brake force
optimally between front and rear
wheels.
This guarantees greater braking stability
for the car, preventing sudden locking
of the rear wheels and the consequent
instability of the car.
ABS
This system, which is an integral part of
the braking system, prevents one or
more wheels from locking and slipping
in all road surface conditions,
irrespective of the intensity of the
braking action, ensuring that the car
can be controlled even during
emergency braking and optimising
stopping distances.
The system intervenes when braking
and the wheels are about to lock,
typically in emergency braking or
low-grip conditions, when locking may
be more frequent.
The system also improves control and
stability of the car when braking on a
surface where the grip of the left and
right wheels varies, or on corners.
65

When two seconds have elapsed,
without starting, the system is
automatically deactivated, gradually
releasing the braking pressure. During
this release stage it is possible to hear a
typical mechanical brake release noise,
indicating the imminent movement of
the car.
IMPORTANT The Hill Holder system is
not a parking brake; therefore, never
leave the car without having engaged
the handbrake, turned the engine
off and engaged first gear, so that it is
parked in safe conditions (for further
information read the "Parking"
paragraph in the "Starting and driving"
chapter).
IMPORTANT There may be situations
on small gradients (less than 8%),
with car laden, in which the Hill Holder
system may not activate, causing a
slight reversing motion and increasing
the risk of collision with another vehicle
or object. The driver is, in any case,
responsible for safe driving.HBA (Hydraulic Brake
Assist) SYSTEM
45) 46) 47)
The HBA system is designed to
improve the car's braking capacity
during emergency braking. The system
detects emergency braking by
monitoring the speed and force with
which the brake pedal is pressed, and
consequently applies the optimal brake
pressure. This can reduce the braking
distance: the HBA system therefore
completes the ABS.
Maximum assistance from the HBA
system is obtained by pressing the
brake pedal very quickly. In addition,
the brake pedal should be pressed
continuously during braking, avoiding
intermittent presses, to get the most
out of the system.
Do not reduce pressure on the brake
pedal until braking is not necessary
anymore.
The HBA system is deactivated when
the brake pedal is released.MSR (Motor
Schleppmoment
Regelung) SYSTEM
This system is an integral part of the
ABS, that intervenes, if there is a
sudden downshifting, restoring torque
to the engine, thereby preventing
excessive drive at the drive wheels
which, especially in poor grip
conditions, could lead to a loss in
stability of the car.
DST SYSTEM (Dynamic
Steering Torque)
This function integrates Dual Pinion
active steering into the operation of
ESC. For particular manoeuvres, the
ESC system controls the steering
to actuate a steering torque and assist
the driver in the best possible way.
The system operates the brakes and
steering in a coordinated manner to
increase the suspension and safety
level of the car as a whole. The steering
provides additional torque on the
steering wheel.
67

41) 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.
42) The ASR system can’t overrule
the natural laws of physics, and
can’t increase the grip available
according to the condition of
the road.
43) The ASR system cannot prevent
accidents, including those due to
excessive speed on corners,
driving on low-grip surfaces or
aquaplaning.
44) The capability of the ASR system
must never be tested irresponsibly
and dangerously, in such a way
as to compromise personal safety
and the safety of others.
45) The HBA system can’t alter the
natural laws of physics, and can’t
increase grip which depends on
the condition of the road.
46) The HBA system cannot prevent
accidents, including those due to
excessive speed on corners,
driving on low-grip surfaces or
aquaplaning.47) The capability of the HBA system
must never be tested irresponsibly
and dangerously, in such a way
as to compromise the safety of
the driver, the other occupants of
the car or any other road user.
“Alfa DNA” SYSTEM
(Car dynamic
control system)This device allows, using lever A fig. 75
(on the central tunnel), three car
response modes to be selected
according to driving style and road
conditions:
❒d=Dynamic(sports driving mode);
❒n=Natural(mode for driving in
normal conditions);
❒a=All Weather(mode for driving in
poor grip conditions, such as rain
and snow).
The device also acts on the dynamic
car control systems (engine, steering,
ESC system, instrument panel).75

When lever A fig. 75 is moved to “d”
position, the activation of “Dynamic”
mode is confirmed by a temporary
variation in the brightness (flashing) of
the instrument panel.
DRIVING MODES
Lever A is monostable type. In other
words, it always remains in a central
position.
The selected driving mode is indicated
by the corresponding LED coming on in
the panel and by an indication on the
reconfigurable multifunction display, as
illustrated below:
❒Dynamic modefig. 76 (display

Move lever A fig. 75 upwards (next to
the letter “d”) and hold in this position
for 0.5 seconds until the corresponding
LED lights up or the word “Dynamic”
appears on the display (see fig. 78).
Upon release, lever A returns to the
central position.
ESC and ASR:intervention thresholds
that allow more enjoyable, sportier
driving whilst guaranteeing stability of
the vehicle.
"ELECTRONIC Q2" system:the
system is calibrated to increase traction
whilst accelerating on bends,
improving the vehicle agilitySteering wheel tuning:uses the
sports mode function.
DST:braking standard control
coordinated with ABS/ESC. Standard
control over lateral acceleration.
Oversteering compensation depending
on the ESC/ASR intervention
thresholds: a slight movement on the
steering wheel encourages the driver to
carry out the most appropriate
manoeuvre.
Engine:prompter response +
Overboost to maximise torque (for
versions/markets, where provided).
RAB:by pre-positioning of the brake
pads (front and rear) following a rapid
release of the accelerator pedal to
reduce braking times, shorten stopping
distances and improve the brake pedal
feeling.
The activation of the Dynamic mode is
also shown by the change in the
instrument panel lighting that, after
decreasing, reaches the highest
luminosity and then returns to the
previously set values.Disengagement
To deactivate “Dynamic” mode and
return to “Natural”, repeat the same
movement of the lever within the same
times. In this case, the LED
corresponding to “Natural” mode will
light up and the words “Natural on” will
appear on the display (see fig. 79).78

letter “a”) and hold in this position for
0.5 seconds until the corresponding
LED lights up or the word “All Weather”
appears on the display (see fig. 80).
ESC and ASR systems:intervention
thresholds aimed at guaranteeing
the maximum safety in low grip driving
conditions. It is recommended to
activate the "All Weather" mode when
fitting snow chains.
"ELECTRONIC Q2" system:the
system is deactivated.
Steering wheel tuning:maximum
comfort.DST:higher braking control
coordinated with ABS/ESC. Standard
control over lateral acceleration.
Oversteering compensation depending
on the ESC/ASR intervention
thresholds: a slight movement on the
steering wheel encourages the driver to
carry out the most appropriate
manoeuvre.
Engine:standard response.Disengagement
To deactivate “All Weather” mode and
return to “Natural”, carry out the same
procedure described for “Dynamic”
mode, but move lever A fig. 75 to “a”.
IMPORTANT
❒It is not possible to switch directly
from “Dynamic” mode to “All
Weather” mode and vice versa. You
must always first go back to “Natural”
mode and then select the other
mode.
❒The driving mode engaged before the
engine stops is maintained when it is
next started.
❒In the event of system failure or a
fault with lever A, no driving modes
can be selected. The display will
show a warning message.80

OPERATING CONDITIONS
50) 51) 52) 53) 54) 55)
The system is active for speeds above
15 km/h.
In a few situations (such as sporty
driving, winter climate or unmade
roads) the signalling may be delayed.
Under special conditions (e.g. car
loaded asymmetrically on one side,
towing a trailer, damaged or worn tyre,
fitting the space-saver wheel, fitting
snow chains, fitting different tyres on
the axles) the system may give false
indications or be temporarily
deactivated.
If the system is temporarily deactivated,
warning light flashes for about 75
seconds and then is continuously on; at
the same time, the display shows the
message "TYRE PRESSURE
MONITORING NOT AVAILABLE".
This indication is displayed also after
the engine has been switched off and
then on again if the correct operating
conditions are not restored.IMPORTANT
INFORMATION
WARNING
50) If the system signals a pressure
decrease on a specific tyre, it is
recommended to check the
pressure on all four tyres.
51) iTPMS does not relieve the
driver from the obligation to check
the tyre pressure every month; it
is not even to be considered a
replacing system for maintenance
or a safety system.
52) Tyre pressure must be checked
with tyres 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, but repeat the
check when tyres are cold.
53) The iTPMS cannot indicate
sudden tyre pressure drops (for
example when a tyre bursts).
In this case, stop the car, braking
with caution and avoiding abrupt
steering.54) The system only warns that the
tyre pressure is low: it is not able
to inflate them.
55) An insufficient tyre inflation
increases fuel consumption,
reduces the tread duration and
may affect the capacity of driving
safely.

EOBD SYSTEM
(European On
Board Diagnosis)(for versions/markets, where provided)
Operation
The EOBD system (European On Board
Diagnosis) carries out a continuous
diagnosis of the components of the car
related to emissions.
It also alerts the driver, by switching on
the
warning light on the instrument
panel, together with a message on
the display, when these components
are no longer in peak condition (see
“Warning lights and messages”
paragraph in the "Knowing the
instrument panel" chapter).
The aim of the EOBD system (European
On Board Diagnosis) is to:
❒monitor the system efficiency;
❒indicate an increase in emissions;
❒indicate the need to replace
damaged components.The car also has a connector, which
can interface with appropriate tools,
that makes it possible to read the error
codes stored in the electronic control
units together with a series of specific
parameters for engine operation and
diagnosis. This check can also be
carried out by the traffic control
authorities.
IMPORTANT After eliminating a fault, to
check the system completely, the Alfa
Romeo Dealership is obliged to run
tests and, if necessary, road tests
which may also require a long journey.
DUAL PINION
ACTIVE STEERINGOperation
This only operates with the key turned
to MAR-ON and the engine started.
The steering allows the force required
at the steering wheel to be adjusted
to suit driving conditions. The different
power assistance modes can be
selected via the d, n, a positions of the
“Alfa DNA System” lever (see paragraph
entitled “Alfa DNA System”).
56)
IMPORTANT After the battery is
disconnected, the steering must be
initialised. The warning light switches on
to indicate this. To carry out this
procedure, simply turn the steering
wheel all the way from one end to the
other or drive in a straight line for about
a hundred metres.
