ESC (Electronic
Stability Control)
SYSTEM
IN BRIEF
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 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.

A0L0145
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 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
The ESC system also includes the
following systems:
❒ ABS
❒ EBD
❒ CBC
❒ DTC
❒ ASR
❒ HILL HOLDER
❒ HBA
❒ "ELECTRONIC Q2" ("E-Q2")
❒ "PRE-FILL" (RAB - Ready Alert
Brake)
SYSTEM ACTIVATION
The ESC system activates automatically
when the engine is started and can
only be deactivated by selecting "Race"
mode. For more details, refer to the
"Alfa DNA system" paragraph in this
chapter.
