During this release stage, the typical
brake disengagement noise
indicating that the vehicle is going to
move imminently will be heard.
Fault indications
Any system fault is indicated by the
turning on of the
warning light on
the instrument panel with digital
display and the
warning light on
the instrument panel with
multifunction display (for versions/
markets where provided) (see
section “Warning lights and
messages”).
IMPORTANT The Hill Holder system
is not a parking brake, therefore
do not leave the vehicle without
activating the handbrake, switching
off the engine and engaging first
gear.

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. 118 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.
