2013 Alfa Romeo Giulietta brake

ABS SYSTEMThe car is fitted with an ABS braking system, which prevents the wheels
from locking when braking, makes the most of road grip and gives
the best control when performing emergency braking under difficult
road conditions.
The EBD system (Electronic Braking Force Distribution) completes the
system allowing the brake force to be distributed between the front and
rear wheels.
IMPORTANT To obtain the maximum efficiency of the braking system,
a bedding-in period of about 500 km is needed: during this period
it is better to avoid sharp, repeated and prolonged braking.
SYSTEM INTERVENTIONIt can be detected because the brake pedal pulsates slightly and the
system gets noisier: it means that the car speed should be altered
to suit the type of road surface.
If the ABS system intervenes, this indicates that the
traction of the tyres on the road is nearing its limit.
Slow down to a speed compatible with the available
traction.The ABS gets the most from the available grip, but it
cannot improve it; you should therefore take every
care when driving on slippery surfaces and not take
unnecessary risks.When the ABS cuts in and you feel the brake pedal
pulsating, do not remove your foot, but keep the pedal
pushed down; in doing so you, will stop in the
shortest distance possible under the road conditions at the time.

ESC (Electronic Stability
Control) SYSTEMThis is an electronic system controlling car stability in the event of tyre
grip loss, helping to maintain directional control.
The system is capable of recognising potentially dangerous situations
in terms of the stability and intervenes automatically on the brakes in a
differentiated manner for the four wheels in order to provide a
stabilising torque.
The ESC system also includes the following systems:
❒Hill Holder
❒ASR
❒Brake Assist
❒MSR
❒CBC
❒“ELECTRONIC Q2” (“E-Q2”)
❒DST
❒RABSYSTEM ACTIVATIONThe ESC system switches on automatically when the engine is started
and cannot be switched off.SYSTEM INTERVENTIONIt is signalled by the flashing of theESCwarning light on the
instrument panel, to inform the driver that the car is in critical stability
and grip conditions.
HILL HOLDER SYSTEMThis system is an integral part of the ESC system and facilitates starting
on slopes.
It is automatically activated in the following conditions:
❒uphill: vehicle stationary on a road with a gradient higher than 5%,
engine running, brake pedal pressed and gearbox in neutral or
gear (other than reverse) engaged;
❒downhill: vehicle stationary on a road with a gradient higher than
5%, engine running, brake pedal pressed and reverse gear
engaged.
When setting off the ESC system control unit maintains the braking
pressure at the wheels until the engine torque required for departure is
reached or for approximately 2 seconds, allowing your right foot to
be moved easily from the brake pedal to the accelerator.
If the vehicle has not departed after this time, the system will deactivate
automatically by gradually releasing the brake force. A sound may
be heard during this stage: this indicates that the vehicle is about
to move off.
IMPORTANT The Hill Holder system is not a handbrake. Do not leave
the vehicle without having engaged the handbrake, switched off the
engine and engaged a gear.

ASR (AntiSlip Regulation) SYSTEMIt is an integral part of the ESC system. It automatically operates in the
event of one or both drive wheels slipping, loss of grip on wet roads
(aquaplaning) and acceleration on slippery, snowy or icy roads, etc.
Depending on the slipping conditions, two different control systems are
activated:
❒if the slipping involves both drive wheels, the ASR intervenes
reducing the power transmitted by the engine;
❒if the slipping only involves one of the drive wheels, the ASR
intervenes automatically braking the wheel that is slipping.
For the correct operation of the ESC and ASR systems,
the tyres must be the same make and type on all
wheels, in perfect condition and, above all, of the type,
make and size recommended.The ESC system operates even when the space-saver
wheel is being used. Always remember that the
space-saver wheel, being smaller than the original
wheel, provides less grip.Do not take unnecessary risks, even if your vehicle is
fitted with the ESC and ASR systems. Driving style must
always be adapted to road conditions, visibility and
traffic. The driver is always responsible for road safety.
BRAKE ASSIST(assistance during emergency braking)
The system, which cannot be turned off, recognises emergency braking
(on the basis of the brake pedal operating speed) and speeding up
the response of the braking system. The Brake Assist device is
deactivated if there is a ESC system failure.MSR SYSTEM(Motor Schleppmoment Regelung)
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.CBC (Cornering Brake Control)
SYSTEMThis function improves the distribution of the braking pressure at the
four wheels (to fully exploit the grip available on the ground) when
braking on bends if the ABS intervenes. This improves stopping
distances and above all vehicle stability when cornering.“ELECTRONIC Q2” SYSTEM (“E-Q2”)The “Electronic Q2” system uses the braking system to create an effect
similar to a limited slip differential.
The front braking system, when accelerating around a curve, acts on
the inside wheel to increase the drive to the outside wheel (increased
load), dynamically and continuously distributing the torque between
the front drive wheels according to driving and road conditions.
The system, combined with MacPherson front suspension, allows
particularly effective and sports driving to be achieved.

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.RAB SYSTEM (Ready Alert Brakes)
(only with “Dynamic” mode
engaged)It is a function that achieves a pre-positioning of the brake pads (front
and rear) following a rapid release of the accelerator pedal to reduce
braking times, shortening stopping distances.
“Alfa DNA” SYSTEM
(Car dynamic control system)This device allows, using lever A fig. 82 (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. 82 is moved to “d” position, the activation of
“Dynamic” mode is confirmed by a temporary variation in the
brightness (flashing) of the instrument panel.

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).
Electronic Q2:improves traction and reduces understeer in
acceleration while exiting curves.
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 reconfigurable multifunction display (see fig.
86).
ENGAGEMENT/DISENGAGEMENT OF
“All Weather” MODEEngagement
Move lever A fig. 82 downwards (to the 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. 87).
ESC and ASR: intervention thresholds for top safety and car control
even in the event of critical road conditions (e.g. in case of rain, snow,
etc.).

ENGINE STOPPING FAILURE
CONDITIONSWhen the system is operating, due to comfort, emission control and
safety reasons, the engine does not stop in some conditions, among
which:
❒engine still cold;
❒especially cold outside temperature;
❒battery not sufficiently charged;
❒particulate filter regeneration (DPF) in progress (diesel engines only);
❒driver's door not shut;
❒driver's seat belt not fastened;
❒reverse gear engaged (for example, for parking manoeuvres);
❒for versions equipped with dual zone automatic climate control (for
versions/markets, where provided), if an adequate level of thermal
comfort has not been reached or with MAX-DEF function activation;
❒during the first period of use, to initialise the system.
If the climate comfort is to be favoured, the Start&Stop
system can be deactivated, for a continuous operation of
the climate control system.
ENGINE RESTARTING CONDITIONSDue to comfort, emission control and safety reasons, the engine can
restart automatically without any action by the driver, under special
conditions, such as:
❒battery not sufficiently charged;
❒reduced braking system vacuum (e.g. if the brake pedal is pressed
repeatedly);
❒car moving (e.g. when driving on roads with a gradient);
❒engine stopping by Start&Stop system for over 3 minutes;
❒for versions equipped with dual zone automatic climate control
system (for versions/markets, where provided), if an adequate level
of thermal comfort has not been reached or MAX-DEF function
activation.
With gear engaged, automatic engine restarting is possible only by
fully depressing the clutch pedal. The driver is informed by the
displaying of a message on the display and - for versions/markets,
where provided - by the flashing of the symbol
.
Notes
If the clutch is not pressed, about 3 minutes after the engine stops, the
engine can be restarted only using the ignition key.
In cases when the engine stops and this is not desired, due for example
to the clutch pedal being released sharply with a gear engaged, if the
Start&Stop system is activated, the engine can be restarted by fully
depressing the clutch pedal or by placing the gear lever in neutral.

OPERATION WITH TRAILERParking sensor operation is deactivated automatically when the trailer
electric cable plug is fitted into the car tow hook socket. The sensors
are automatically enabled again when the trailer's cable plug is
removed.
The sensor must be free of mud, dirt, snow or ice in order
for the system to work. 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.When repainting the bumpers or touching up paint in
the sensor area, contact Alfa Romeo Authorized
Services only. Incorrect paint application could affect
the operation of the parking sensors.Parking manoeuvres however are always the driver’s
responsibility. When carrying out such manoeuvres,
always ensure that the manoeuvring area is free of
people (particularly children) and animals. The parking sensor is
designed to assist drivers, who must still never allow their
attention to lapse during potentially dangerous manoeuvres even
if performed at low speed.
GENERAL WARNINGSDuring parking manoeuvres, pay the utmost attention to any obstacles
that could be located above or below the sensors.
Objects located near the rear of the car are not detected under certain
circumstances and could therefore cause damage to the car or be
damaged.
The following conditions may influence the performance of the parking
sensor system:
❒reduced sensor sensitivity and a reduction in the parking assistance
system performance could be due to the presence on the surface of
the sensor of: ice, snow, mud, thick paint
❒the sensors may detect a non-existent obstacle (echo interference)
due to mechanical interference, for example when washing the
car, in rain (strong wind), hail;
❒The signals sent by the sensors can also be altered by the presence
of ultrasonic systems (e.g. pneumatic brake systems or pneumatic
drills) near the vehicle.
❒sensor performance can also be influenced by the position of the
sensors. For example by a change in the ride setting (caused by
the wear of the shock absorbers, suspension), overloading the
vehicle and carrying out specific tuning operations that require the
vehicle to be lowered;
❒The detection of obstacles at the top part of the car may not be
guaranteed because the system detects obstacles that could cause an
impact with the car in the bottom part.

STARTING AND DRIVING
STARTING THE ENGINEPROCEDURE FOR PETROL VERSIONSProceed as follows:
❒engage the handbrake and place the gearbox lever in neutral;
❒fully depress the clutch pedal, without touching the accelerator;
❒turn the ignition key to AVV and release it as soon as the engine
starts.
IMPORTANT
❒If the engine does not start at the first attempt, return the ignition key
to STOP before repeating the starting procedure.
❒If, when the ignition key is at MAR, the instrument panel warning
light
remains on together with warning light
, turn the
key to STOP and then back to MAR; if the warning light remains on,
try the other keys provided. If you are still unable to start the engine
contact Alfa Romeo Authorized Services.
❒Never leave the ignition key at MAR when the engine is stopped.
PROCEDURE FOR DIESEL VERSIONSProceed as follows:
❒engage the handbrake and place the gearbox lever in neutral;
❒turn the ignition key to MAR: the warning lights
and
on
the instrument panel will switch on;
❒wait for the warning lights to switch off;❒fully depress the clutch pedal, without touching the accelerator;
❒turn the ignition key to AVV;
warning light switches off.
Waiting too long will waste the heating work carried out by the
glow plugs. Release the key as soon as the engine starts.
If the
warning light flashes for about 1 minute after
starting or during prolonged cranking, this indicates a fault
in the glow plug preheating system. Use the car normally
if the engine starts and go to Alfa Romeo Authorized Services as soon
as possible.
It is dangerous to run the engine in enclosed areas. The
engine takes in oxygen and releases carbon dioxide,
carbon monoxide and other toxic gases.It is advisable not to demand maximum performance from
your car (e.g. excessive acceleration, long distances at
maximum rpm, excessively intense braking, etc.) when it is
first used.When the engine is off, do not leave the ignition key turned
to MAR to prevent unnecessary electrical consumption from
draining the battery.
