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

System intervention
A slight pulsing of the brake pedal and
noise indicates the intervention of the
ABS: this is completely normal when
the system intervenes.
35) 36) 37) 38) 39) 40) 41)
CBC (Cornering Brake
Control) SYSTEM
The system acts when braking on
corners, optimising the distribution of
brake pressure on the four wheels: the
system prevents the wheels on the
inside of the corner (less affected by the
weight of the car) from locking,
ensuring better stability and direction
for the car.ASR (Anti-Slip
Regulation) SYSTEM
42) 43) 44)
This is an integral part of the ESC
system and 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 system intervenes,
reducing the power transmitted by
the engine;
❒if the slipping only involves one of the
drive wheels, it also intervenes
automatically, braking the wheel that
is slipping.
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.HILL HOLDER SYSTEM
This is an integral part of the ESC
system and facilitates starting on
slopes, activating automatically in the
following cases:
❒uphill: car stationary on a road with a
gradient higher than 5%, engine
running, brake pressed and gearbox
in neutral or gear (other than reverse)
engaged;
❒downhill: car stationary on a road
with a gradient higher than 5%,
engine running, brake pressed and
reverse gear engaged.
When setting off, the ESC system
control unit maintains the braking
pressure on the wheels until the engine
torque necessary for starting is
reached, or in any case for a maximum
of 2 seconds, allowing your right foot
to be moved easily from the brake
pedal to the accelerator.
66
GETTING TO KNOW YOUR CAR

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

“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.
WARNING
30) The ESC system can’t alter the
natural laws of physics, and can’t
increase grip which depends on
the condition of the road.
31) The ESC system cannot prevent
accidents, including those due to
excessive speed on corners,
driving on low-grip surfaces or
aquaplaning.
32) 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.
33) For the correct operation of the
ASR 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.
34) The performance of the ESC
and ASR systems must not
encourage the driver to take
unnecessary risks. Your driving
style must always be suited to the
road conditions, visibility and
traffic. The driver is always
responsible for road safety.35) When the ABS intervenes and
you feel the brake pedal pulsating,
do not reduce the pressure, but
hold it down firmly and
confidently; in doing so you will
brake in the shortest distance
possible, depending on the
current road conditions.
36) For maximum efficiency of the
braking system, a bedding-in
period of about 500 km is
required: during this period it is
advisable to avoid sharp, repeated
and prolonged braking.
37) 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.
38) The ABS can’t overrule the
natural laws of physics, and can’t
increase the grip available
according to the condition of the
road.
39) The ABS cannot prevent
accidents, including those due to
excessive speed on corners,
driving on low-grip surfaces or
aquaplaning.
40) 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.

GETTING TO KNOW YOUR CAR

ENGAGEMENT/
DISENGAGEMENT OF
“Dynamic” MODE
Engagement
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

WARNING
105) Press the clutch pedal fully to
change gears correctly. It is
therefore essential that there is
nothing under the pedals: make
sure the mats are lying flat and do
not get in the way of the pedals.
IMPORTANT
20) Do not drive with your hand
resting on the gear lever as the
force exerted, even if slight, could
lead over time to premature wear
of the gearbox internal
components.
ALFA TCT(for versions/markets, where provided)
IN BRIEF
The car can be equipped with an
electronically managed Alfa TCT
6-speed automatic transmission
where gearshifting takes place
automatically according to the
instantaneous car usage parameters
(car speed, road gradient and
accelerator pedal position).
The new transmission is an absolute
innovation as it matches the
Start&Stop system with the most
recent alternative to traditional
automatic transmissions with built-in
torque converter.
Manual gearshifting can still occur
thanks to the sequential mode
position of the gear lever.
SELECTOR LEVER
The lever fig. 128 (left hand drive
versions) or fig. 129 (right hand drive
versions), can be placed in the following
positions:
❒P= Park
❒R= Reverse❒N= Neutral
❒D= Drive, (automatic forward speed)
❒+= Sequential upshifting
❒−= Sequential downshifting
If the lever is used in sequential mode,
moving the latter from D to the left,
the positions towards + or – are
unstable.
The lever has a button A, which must
be pressed to move the lever to P or R.
128 - Left hand drive versions
A0K0617
129 - Right hand drive versions
A0K0618
157

If, with 1
stgear or reverse (R) engaged,
the following conditions occur:
❒road slope over 5%;
❒clutch overheated;
❒engine torque constant for a given
period (e.g. if the car hits the
pavement or is parked downhill/
uphill);
car movement is achieved by pressing
the accelerator pedal.
IMPORTANT With handbrake released
and brake pedal released, engine at
idling speed and gear lever in position
D, R or sequential, pay the utmost care
because the car can move even
without the operation of the accelerator
pedal. This condition can be used
with the car on a level surface during
tight parking manoeuvres using the
brake pedal only.
AUTOMATIC DRIVING
MODE
D can be selected from sequential
operation in any driving conditions.
In automatic driving mode, the best
ratio is selected by the electronic
transmission control unit depending on
speed, engine load (accelerator pedal
position) and gradient of the road.“Kick-Down” function
To resume speed quickly, when the
accelerator pedal is pressed fully, the
transmission control system downshifts
("Kick-down" function).
IMPORTANT When driving on roads
with poor grip conditions (snow, ice,
etc.) avoid activating the kick-down
function.
Integration with "Alfa
DNA" system
Operating the “Alfa DNA” system fig.
134, three different driving modes can
be selected:
❒“Dynamic”: gear changes at higher
engine speeds. It enhances sporty
driving;❒“Natural”: gear changes at low
engine speeds. It enhances comfort
and reduces consumption;
❒“All Weather”: driving programme on
roads with poor grip (e.g. snow, ice,
mud, etc.).
Gearshifting suggestion
With the transmission in automatic
mode (selector lever in position D),
when gearshifting is required by the
paddles on the steering wheel (for
versions/markets, where provided), the
system shifts to "Sequential mode",
with relevant displaying of the gear
engaged, for about 5 second.
When this time has elapsed, if the
paddles are not operated anymore, the
system goes back to the automatic
mode (D), with following displaying.
SEQUENTIAL DRIVING
MODE
In sequential driving mode, the
transmission works like a manual
gearbox.
134

161

If reverse (R) is engaged, only engage
the 1
stgear (or vice versa) when the car
is completely stopped.
Although it is highly inadvisable, if you
are driving downhill and, for unexpected
reasons, you let the car move forward
with the transmission in neutral (N),
when there is a request to engage
a gear, depending on the speed of the
car, the system will automatically
engage the best gear for the correct
transmission of drive torque to the
wheels.
107)IMPORTANT
21) If the car is on a gradient, always
pull the handbrake BEFORE
placing the gear lever in P.
22) Engage reverse only with the car
stationary, engine at idling speed
and accelerator fully released.
WARNING
106) Using the levers incorrectly
(levers pushed towards the
dashboard, see fig. 137) could
break them.
107) Never leave children
unattended in the car. Always
remove the ignition key when
leaving the car and take the key
with you.
SAVING FUELHere are some suggestions which can
help you to save fuel and lower harmful
emissions.
GENERAL
CONSIDERATIONS
Car maintenance
Checks and adjustments should be
carried out in accordance with the
“Scheduled Servicing Plan” (see
chapter “Maintenance and care”).
Tyres
Check the tyre pressures at least once
every four weeks: if the pressure is
too low, consumption levels increase as
resistance to rolling is higher.
Unnecessary loads
Do not travel with an overloaded boot.
The weight of the car and its
arrangement greatly affect fuel
consumption and stability.
164
STARTING AND DRIVING

Roof rack/ski rack
Remove the roof rack or the ski rack
from the roof after use. These
accessories lower aerodynamic
penetration and adversely affect
consumption levels. When transporting
particularly large objects, use a trailer
if possible.
Electrical devices
Use the electrical devices only for the
necessary amount of time. The heated
rear window, additional headlights,
screen wipers and heater fan require a
considerable amount of energy;
increasing the current uptake increases
fuel consumption (by up to +25% in
an urban cycle).
Climate control system
Using the climate control system will
increase consumption: use the air vents
when the temperature outside permits.
Devices for
aerodynamic control
The use of non-certified devices for
aerodynamic control may adversely
affect air drag and fuel consumption.DRIVING STYLE
Starting
Do not warm up the engine at low or
high revs when the car is stationary;
this causes the engine to warm up
more slowly, thereby increasing fuel
consumption and emissions. It is
therefore advisable to move off
immediately, slowly, avoiding high
speeds: in this way the engine will
warm up more quickly.
Unnecessary actions
Avoid accelerating when stopped at
traffic lights or before switching off the
engine. The latter action, as well as
double-declutching, is unnecessary and
causes increased fuel consumption
and pollution.
Gear selection
Use a high gear when traffic and road
conditions allow it. Using a low gear for
faster acceleration will increase fuel
consumption. In the same way
improper use of a high gear increases
consumption, emissions and engine
wear.Maximum speed
Fuel consumption considerably
increases as speed increases. Maintain
a constant speed, avoiding
unnecessary braking and acceleration,
which cost in terms of both fuel
consumption and emissions.
Acceleration
Accelerating violently severely affects
consumption and emissions:
acceleration should be gradual and
should not exceed the maximum
torque.
