Operation Manual

ASR SYSTEM (Antislip
Regulator)
This is a traction control system that
cuts in automatically every time one or
both drive wheels slip.
Depending on the slipping conditions,
two different control systems are
activated:
❒ if the slipping involves both drive
wheels, the ASR intervenes reducing
the power transmitted by the engine;
❒ if the slipping only involves one of the
drive wheels, it intervenes
automatically braking the wheel that
is slipping.
The action of the ASR system is
particularly helpful in the following
circumstances:
❒ slipping of the inner wheel on bends
due to dynamic variations in the load
or excessive acceleration;
❒ excessive power transmitted to the
wheels, also in relation to road
surface conditions;
❒ acceleration on slippery, snowy or icy
road surfaces;
❒ loss of grip on wet road surfaces
(aquaplaning).
MSR system (engine
drive regulation)
This is a system that, in the event of a
sudden gear down shift, cuts in and
provides torque to the engine thus
preventing excessive drive wheel drive
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.
Whilst driving, the ASR can be switched
off and subsequently switched on
again by pressing the fig. 122 button on
the dashboard.
Switching off is shown by the
warning light on the instrument panel
switching on and a dedicated message
shown in the multifunction display,
where provided.
If the ASR is switched off when driving,
it is automatically switched on again
when the vehicle is started up.
When travelling on snowy roads with
snow chains, it may be helpful to turn
the ASR off: in fact, in these conditions,
the driving wheels slipping when
moving off gives you better traction.
