MSR system
(engine braking torque control)
It is an integral part of the ASR system that
in case of sudden gear downshifting, cuts
in providing torque to the engine thus pre-
venting excessive driving wheel drive that,
specially in poor grip conditions, can lead
to loss of stability.
TTC SYSTEM
(Torque Transfer Control)
It is an integral part of the ESP system.
This system improves the transfer of dri-
ve torque to the wheels, guaranteeing
safer and more sporty driving, especially
when cornering, far more able to prevent
understeer.
The system is turned on by pressing the
button in the dashboard C-Fig. 58. The
LED in the TTC button is lit up when it
is on.
It is turned off by pressing the button again
or when the vehicle is switched off (igni-
tion key in STOP position).
ASR SYSTEM
(Antislip Regulation)
It’s integral to the ESP system and auto-
matically intervenes in case of slip of one
or both drive wheels, helping the driver
to control the car.
The action of the ASR is particularly help-
ful in the following circumstances:
❒ slipping of the inner wheel due to the
effect of dynamic load changes or ex-
cessive acceleration;
❒ too much power transmitted to the
wheels also in relation to the conditions
of the road surface;
❒ acceleration on slippery, snowy or
frozen surfaces;
❒ in the case of loss of grip on a wet sur-
face (acquaplaning).
