Alfa Romeo Giulietta 2013 Owner handbook (in English)

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.

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.

SAFETY FUNCTIONSWhen the engine is stopped by the Start&Stop system, if the driver
releases his/her seat belt and opens the driver's or passenger's door,
the engine can be restarted only using the ignition key.
The driver is informed by a buzzer and by the flashing of the symbol
on the display; on some versions, a message is displayed as well.
"ENERGY SAVING" FUNCTION(for versions/markets, where provided)
If, following automatic engine restarting, the driver does not carry out
any action on the car for over 3 minutes, the Start&Stop system stops
the engine once and for all, to prevent fuel consumption. In these
cases, the engine can be restarted only using the ignition key.
NOTE In any case, it is possible to keep the engine running by
deactivating the Start&Stop system.IRREGULAR OPERATIONIn the event of malfunction, the Start&Stop system is deactivated.
The driver is informed of the fault by the flashing
symbol (versions
with multifunction display) or
symbol (versions with reconfigurable
multifunction display). For versions/markets where provided, a
message is also displayed.
In this case, contact Alfa Romeo Authorized Services.
CAR INACTIVITYIn the event of car inactivity (or if the battery is replaced), special
attention must be paid to the disconnection of the battery power
supply.
Proceed as follows: detach the connector A fig. 90 (by pressing button
B) from sensor C for monitoring the status of the battery installed on
the negative battery pole D. This sensor should never be disconnected
from the pole except if the battery is replaced.
In case of battery replacement, always contact Alfa
Romeo Authorized Services. Replace the battery with
one of the same type (HEAVY DUTY) and with the same
specifications.
IMPORTANT After turning the ignition key to STOP, wait at least 1
minute before disconnecting the electrical supply to the battery.

JUMP STARTINGWhen jump starting, never connect the negative lead (–) of the
auxiliary battery to the negative pole A fig. 91 of the car battery, but
rather to an engine/gearbox earth point.
Before opening the bonnet, make sure the engine is off and
the ignition key is in the STOP position. Follow the
instructions on the label on the front crossmember (fig. 92).
It is advisable to extract the key when there are other people in the
vehicle. Exit from the car only after having removed the ignition key or
having rotated it to the STOP position. During refuelling, make sure
that the engine is off and that the ignition key is in the STOP position.
EOBD SYSTEM (European On
Board Diagnosis)(for versions/markets, where provided)
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 diagnostic connector that can be interfaced with
appropriate tools, which 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 police.
IMPORTANT After eliminating a fault, to check the system completely,
Alfa Romeo Authorised Services are obliged to run tests and, if
necessary, road tests which may also call for a long journey.
