190 STARTING AND OPERATING

System Failure
In the event of system failure or a fault with the gear
selector, no driving modes can be selected.
The display will become grey (same screen asNatural
mode) but without an indication of the Alfa DNA setting.
The display will also show a warning message.
Please contact your authorized dealer for service.
Launch Control
The Launch Control strategy permits high-performance
acceleration from stand still.
This strategy can be activated with vehicle at a standstill,
Race mode selected and FIRST (1st) gear engaged.
The sequence of operations to perform is as follows:
1. Press the brake pedal and hold it down.
2. Press the accelerator pedal and hold it down. 3. Press the
–paddle behind the steering wheel. (This
allows the engine to rev above the 3000 RPM limit.)
When the brake pedal is released, the vehicle will start
with maximum acceleration. Despite the MANUAL
mode, the vehicle will automatically shift the gear to
guarantee maximum acceleration, once the correct shift-
ing speed has been reached.
WARNING!
Launch Control is intended for off-highway or off-
road use only and should not be used on any public
roadways. Use Launch Control only in a controlled
and dry track environment; within the limits of the
law. Actual Launch Control performance may change
depending on the surface and current traction condi-
tions. The capabilities of the vehicle as measured by
the performance pages must never be exploited in a

WARNING!
•Driving through standing water limits your vehi-
cle’s traction capabilities. Do not exceed 5 mph
(8 km/h) when driving through standing water.
• Driving through standing water limits your vehi-
cle’s braking capabilities, which increases stopping
distances. Therefore, after driving through stand-
ing water, drive slowly and lightly press on the
brake pedal several times to dry the brakes.
• Failure to follow these warnings may result in
injuries that are serious or fatal to you, your pas-
sengers, and others around you.
CAUTION!
• Always check the depth of the standing water
before driving through it. Never drive through

CAUTION! (Continued)
standing water that is deeper than the bottom of
the tire rims mounted on the vehicle.
• Determine the condition of the road or the path
that is under water and if there are any obstacles in
the way before driving through the standing water.
• Do not exceed 5 mph (8 km/h) when driving
through standing water. This will minimize wave
effects.
• Driving through standing water may cause damage
to your vehicle’s drivetrain components. Always
inspect your vehicle’s fluids (i.e., engine oil, trans-
mission, axle, etc.) for signs of contamination (i.e.,
fluid that is milky or foamy in appearance) after
driving through standing water. Do not continue to
operate the vehicle if any fluid appears contami-
nated, as this may result in further damage. Such

Warranty.
• Getting water inside your vehicle’s engine can
cause it to lock up and stall out, and cause serious
internal damage to the engine. Such damage is not
covered by the New Vehicle Limited Warranty.
PARKING BRAKE
Before leaving the vehicle, make sure that the parking
brake is fully applied. Also, be certain to leave manual
transmission in REVERSE (R) or FIRST (1st) gear.
The parking brake lever is located in the central tunnel.
To apply the parking brake, pull the parking brake lever
up as firmly as possible. To release the parking brake,
pull the parking brake lever up slightly, push the center
button, then lower the parking brake lever completely. When the parking brake is applied with the ignition
switch in the MAR (ACC/ON/RUN) position, the Brake
Warning Light in the instrument cluster will illuminate.
When parking on a hill, it is important to turn the front
wheels toward the curb on a downhill grade and away
from the curb on an uphill grade. The parking brake

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 vehicle 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 vehicle.
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

•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 the
systems 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 selecting Race
mode. Refer to the Six-Speed Alfa Twin Clutch Trans-
mission in 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 vehicle
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.
This guarantees greater braking stability for the vehicle,
preventing sudden locking of the rear wheels and the
consequent instability of the vehicle.
Four-Wheel Anti-Lock Brake System (ABS)
The Four-Wheel ABS is designed to aid the driver in
maintaining vehicle control under adverse braking con-
ditions. The system operates with a separate computer to
modulate hydraulic pressure, to prevent wheel lock-up
and to help avoid skidding on slippery surfaces.

WARNING!(Continued)
compromise personal safety and the safety of oth-
ers.
• For the correct operation of the ABS, the tires must
of necessity be the same make and type on all
wheels, in perfect condition and, above all, of the
prescribed type and dimensions.
When you are in a severe braking condition involving the
use of the ABS, you will experience some pedal drop as
the vehicle comes to a stop. This is the result of the
system reverting to the base brake system.
Engagement of the ABS may be accompanied by a
pulsing sensation. You may also hear a clicking noise.
These occurrences are normal and indicate that the
system is functioning properly.
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.
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 vehicle) from locking,
ensuring better stability and direction for the vehicle.
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 vehicle
stability, above all in low-grip conditions.
5
STARTING AND OPERATING 201

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 vehicle
is in critical stability and grip conditions.
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: vehicle stationary on a road with a gradient
higher than 5%, engine running, brake pressed and
transmission in neutral (N) or gear other than reverse
engaged.
• Downhill: vehicle 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
vehicle is going to move imminently, can be heard.
