DASHBOARD AND CONTROLS

MSR system (engine braking
torque control)

It is an integral part of the ASR system that
in case of sudden gear shifting, cuts in pro-
viding torque to the engine thus prevent-
ing excessive driving wheel drive that, spe-
cially in poor grip conditions, can lead to
loss of stability.

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).

For correct operation of the
ESP and ASR systems, the

tyres must absolutely be of the same
brand and type on all wheels, in per-
fect conditions and, above all, of
type, brand and size specified.

WARNING

ASR SYSTEM (Antislip Regulator)

The ASR function controls car drive and
cuts in automatically every time one or
both driving wheels slip.

According to slipping conditions, two dif-
ferent control systems are activated:
❒ if slipping involves both driving wheels,

the ASR function intervenes reducing
the power transmitted by the engine;

❒ if the slipping involves only one driving

wheel, the ASR system cuts in auto-
matically braking the wheel that is slip-
ping.
