steering Alfa Romeo Giulietta 2015 User Guide

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.“ELECTRONIC Q2”
SYSTEM (“E-Q2”)
The "Electronic Q2" system intervenes
during acceleration on corners, braking
the inner drive wheel and thus
increasing the traction of the outer
wheel (which bears more of the car’s
weight): the torque is thus distributed
optimally between the drive wheels
in accordance with the driving
conditions and road surface, permitting
particularly effective, sporty driving.
"PRE-FILL" SYSTEM
(RAB - Ready Alert
Brake)
(only with 'Dynamic" mode activated)
This function activates automatically
if the accelerator pedal is released
rapidly, reducing the brake pad travel
(both at front and back), with the aim of
preparing the braking system and
enhancing its responsiveness, thus
reducing the stopping distance in the
event of subsequent braking.

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,
VDC system, instrument panel).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:

IMPORTANT For versions/markets,
where provided, switching to "Dynamic"
mode is automatically disabled in the
first kilometres in order to guarantee
correct settling of the mechanical
components. If an attempt to activate
the system is made before this limit, the
display will show a dedicated message
to remind the driver that this request
cannot be fulfilled.

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).ENGAGEMENT/
DISENGAGEMENT OF “All

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, particular conditions of the road
surface (e.g. icy, snowy, unsurfaced
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, use of the
"Fix&Go Automatic" kit, 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
the
warning light flashes for about
75 seconds and then is continuously
on; at the same time, the display shows
a dedicated message.
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.

or partial in detecting the contemporary
deflation of more than one tyre.

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 STEERING
Operation
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.
