MSR system
(engine drive regulator)
This is an integral part of the ASR system that, in the event
of a sudden gear down shift, cuts in and provides torque
to the engine thus preventing excessive drive wheel dri-
ve which, especially in poor grip conditions, can lead to
a loss of stability.
Engagement/disengagement of the ASR system
The ASR system switches on automatically each time the
engine is started.
When travelling, the ASR can be switched off and on again
by pressing switch fig. 101, which can be found between
the front seats to the side of the handbrake lever.
When the ASR is switched off, this is shown by the LED
on the switch coming on and by the relevant message ap-
pearing on the multifunction display, where provided.
ASR SYSTEM (Anti-slip Regulator)
This is a traction control system that cuts in automatical-
ly every time one or both drive wheels slip.
Depending on the slipping conditions, two different con-
trol systems are activated:
❒ if both drive wheels are slipping, the ASR function in-
tervenes by reducing the power transmitted by the en-
gine;
❒ if the slipping only involves only one drive wheel, the
ASR system cuts in by automatically braking the wheel
that is slipping.
The action of the ASR system is especially useful in the fol-
lowing conditions:
❒ slipping of the inner wheel when cornering due to the
effect of dynamic load changes or excessive accelera-
tion;
❒ too much power transmitted to the wheels also in re-
lation to the conditions of the road surface;
❒ acceleration on slippery, snowy or icy surfaces;
❒ in the case of loss of grip on a wet surface (aquaplan-
ing).
For the correct operation of the ESP and
ASR systems, the tyres must absolutely be
the same make and type on all wheels, in perfect
condition and, above all, of the type, make and
size specified.
