To make ESP, ASR and

ABS systems work prop-

erly, the tyres must

absolutely be of the same brand

and type on all wheels, in perfect

conditions and, above all, of type,

brand and size specified.

stantly changed and controlled in

the attempt to keep the driver’s

direction.

The ESP system considerably

increases the car safety in several

critical conditions and it is particu-

larly useful during overtaking, when

the grip conditions on the road bed

change.

ASR FUNCTION (ANTISLIP

REGULATION)

General

The ASR function is part of the

ESP system and it checks the car

drive, taking action every time one

or both driving wheels slip, thus pre-

venting car instability and tyre wear. 

On the basis of slipping conditions,

two different check systems are acti-

vated:

– if slipping affects both driving

wheels, as a result of the excessive

force transmitted, the ASR function

reduces the power supplied by the

engine;

– if slipping affects only one of the

driving wheels, the ASR function

automatically brakes the slipping

wheel, with an effect similar to the

self-locking differential.

The action of the ASR function is

particularly useful in the following

conditions:

– internal wheel slipping when cor-

nering due to load dynamic varia-

tions and excessive acceleration;

– excessive power supplied to

wheels according to the road bed;

– acceleration on slippery ground,

covered with snow or ice;

– in case of grip loss on wet ground

(aquaplaning).

ASR function activation

The ASR function is activated

automatically whenever the engine

is started.

During driving it is possible to dis-

engage and engage this function by

pressing button A (fig. 142) on the

central console.

When the ASR function is on, sym-

bol V is lighted on the multifunc-

tion display together with the mes-

sage “ASR ON”.
