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.

Switching the system

on/off fig. 97

The ASR system switches on automatically

each time the engine is started.

When travelling, the ASR can be switched

off and on again pressing button A set on

the dashboard fig. 97.

When the ASR is switched off this is

shown by the lighting up of the led on the

button and by relevant message on the

multifunction display, where provided.

If the ASR is switched off when travelling,

it will turn on again automatically the next

time the engine is started.

It may be useful to switch the ASR when

driving on snow-covered roads with snow

chains fitted: in these conditions, slipping

of the wheels during pick-up provides bet-

ter traction.

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.

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.

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).
