152 STARTING AND OPERATING

During prolonged stops with the engine running, it is
advisable to keep the transmission in NEUTRAL (N).
When stopped on an incline, always hold the vehicle in
place using the brakes. On steep inclines, Hill Start Assist
(HSA) will temporarily hold the car in position when the
brake pedal is released. If the accelerator pedal is not
applied after a short time, the car will roll back. Either
reapply the brake (to hold the vehicle) or press the
accelerator to climb the hill.
Only shift between FIRST (1st) and REVERSE (R) when
completely stopped, with the brake pedal pressed.
When necessary, it is possible to engage FIRST (1st),
REVERSE (R) or NEUTRAL (N) with the engine off, the
key at MAR-ON and the brake pressed. In this case, wait
at least five seconds between one gear change and the
next, in order to safeguard the operation of the hydraulic
system, and the pump in particular.For uphill departures, it is advisable to accelerate gradu-
ally but fully immediately after releasing the parking
brake or the brake pedal; this allows the engine to
temporarily increase the number of revs and tackle the
steepest gradients with more torque at the wheels.
ALFA DNA SYSTEM (DYNAMIC CAR CONTROL
SYSTEM)
This vehicle is equipped with a “Alfa DNA” system lever
(located on the center console). There are four modes of
operation to be selected according to driving style and
road conditions:
Dynamic (This mode alters the transmission’s automatic
shift schedule for sportier driving [D]).
Natural (mode for driving in normal conditions [N]).
All Weather (mode for driving in poor grip conditions,
such as rain and snow [A]).5
STARTING AND OPERATING 163

CAUTION!
If the Brake Warning Light remains on with the
parking brake released, a brake system malfunction
is indicated. Have the brake system serviced by an
authorized dealer immediately.
BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic brake
systems. If either of the two hydraulic systems loses
normal capability, the remaining system will still func-
tion. However, there will be some loss of overall braking
effectiveness. You may notice increased pedal travel
during application, greater pedal force required to slow
or stop, and potential activation of the “Brake System
Warning Light.”In the event power assist is lost for any reason (i.e.,
repeated brake applications with the engine off) the
brakes will still function. However, the effort required to
brake the vehicle will be much greater than that required
with the power system operating.
ESC (ELECTRONIC STABILITY CONTROL)
SYSTEM
The ESC system improves the directional control and
stability of the vehicle in various driving conditions.
The ESC system corrects the car ’s understeer and over-
steer, 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.5
STARTING AND OPERATING 175

the real trajectory deviates from the desired trajectory, the
ESC system intervenes to counter the car ’s understeer or
oversteer.
•Oversteer: occurs when the vehicle is turning more
than it should according to the angle of the steering
wheel.
•Understeer: occurs when the vehicle is turning less
than it should according to the angle of the steering
wheel.
This vehicle’s advanced electronic brake control system
also includes: Electronic Brake Distribution (EBD), Anti-
Lock Brake System (ABS), Cornering Brake Control Sys-
tem (CBC), Drag Torque Control System (DTC), AntiSlip
Regulation System (ASR), Hill Start Assist (HSA), Hy-
draulic Brake Assistant System (HBA), ELECTRONIC Q2
system (E-Q2) and Ready Alert Brake (RAB). All of thesystems work together to enhance vehicle stability and
control in various driving conditions, and are commonly
referred to as ESC.
System Activation
The ESC system activates automatically when the engine
is started and can only be deactivated by selectingRace
mode. Refer to theSix-Speed Alfa Twin Clutch Trans-
missionin this section for further information.
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.
Electronic Brake Distribution System (EBD)
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.
5
STARTING AND OPERATING 177

Cornering Brake Control System (CBC)
The system acts when braking on corners, optimizing 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.
Drag Torque Control System (DTC)
This is an integral part of the ESC system and intervenes
in the event of sudden downshifting, or during braking
when the ABS intervenes, restoring torque to the engine
and thus preventing excessive drag at the drive wheels,
which may lead the wheels to lock and a loss of car
stability, above all in low-grip conditions.
AntiSlip Regulation System (ASR)
WARNING!
•Electronic Stability Control (ESC) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded by
prevailing road conditions. ESC cannot prevent all
collisions, including those resulting from excessive
speed in turns, driving on very slippery surfaces, or
hydroplaning. ESC also cannot prevent collisions
resulting from loss of vehicle control due to inap-
propriate driver input for the conditions. Only a
safe, attentive, and skillful driver can prevent col-
lisions.The capabilities of an ESC equipped ve-
hicle must never be exploited in a reckless or
dangerous manner which could jeopardize the us-
er ’s safety or the safety of others.
(Continued)
180 STARTING AND OPERATING

Hill Start Assist (HSA)
This is an integral part of the ESC system and facilitates
starting on slopes, activating automatically in the follow-
ing cases:
•Uphill: car stationary on a road with a gradient higher
than 5%, engine running, brake pressed and transmis-
sion in neutral (N) or gear other than reverse engaged.
•Downhill: car stationary on a road with a gradient
higher than 5%, engine running, brake pressed and
reverse (R) 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 two seconds, allowing your right foot to
be moved easily from the brake pedal to the accelerator.When the two seconds have elapsed, without starting,
the system is automatically deactivated, gradually releas-
ing the braking pressure. During this release stage, the
typical brake disengagement noise, indicating that the
car is going to move imminently, can be heard.
NOTE:
•HSA is not a parking brake; therefore, never leave the
vehicle without having engaged the parking brake,
turned the engine off and engaged first gear, so that
the vehicle is parked in safe conditions.
•There may be situations on small gradients (less than
8%), with vehicle laden, in which the Hill Holder
system may not activate, causing a slight reversing
motion and increasing the risk of collision with an-
other vehicle or object. The driver is, in any case,
responsible for safe driving.
182 STARTING AND OPERATING

Electronic Q2 System (E-Q2)
TheElectronic Q2system intervenes during accelera-
tion 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 par-
ticularly effective, sporty driving.
Ready Alert Brake System (RAB)
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 subse-
quent braking.

CAUTION!
Driving with a hot cooling system could damage
your vehicle. If the temperature gauge reads 240°F
(116°C) or greater pull over and stop the vehicle. Idle
the vehicle with the air conditioner turned off until
the coolant temperature drops back into the normal
range 200–230°F (93–110°C). The digital warning light
may switch on (together with a message on the
display) to indicate that the coolant temperature is
too high; in this case, stop the engine and call for
service.
WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If
you see or hear steam coming from under the hood,
do not open the hood until the radiator has had time
to cool. Never try to open a cooling system pressure
cap when the radiator or coolant bottle is hot.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to ensure
that the wheel is properly mounted to the vehicle. Any
time a wheel has been removed and reinstalled on the
vehicle the lug nuts/bolts should be torqued using a
properly calibrated torque wrench.
