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.

Switching the ASR system
on/off fig. 61

The ASR system switches on automatically
each time the engine is started.

The ASR system can be turned off by
pressing the button C ASR OFF.

When the system is active, a message on
the reconfigurable multifunctional display
(for versions/markets, where provided) is
displayed.

When the system is not active, the led on
the button ASR OFF turns on and a mes-
sage on the reconfigurable multifunction-
al display (for versions/markets, where
provided) is displayed. Turning off the ASR
when travelling, on next start the ASR is
automatically turned on by the system.

It may be useful to switch off the ASR
when driving on snow-covered roads with
snow chains fitted: in these conditions,
slipping of the wheels during pick-up pro-
vides better traction.

ASR SYSTEM
(Antislip Regulation)
(for versions/markets, where provided)

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 (aquaplaning).
