WARNING! (Continued)
or poor vehicle maintenance that reduces the effec-
tiveness of the ESC system can increase the risk of
loss of vehicle control, vehicle rollover, personal in-
jury and death.
The ESC system uses sensors installed on the vehicle to
determine the trajectory that the driver intends to follow
and compares it with the vehicles effective trajectory.
When the real trajectory deviates from the desired trajec-
tory, the ESC system intervenes to counter the vehicles
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 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-
