When setting off, the ESC system
control unit maintains the braking
pressure on the wheels until the torque
necessary for starting is reached, or
in any case for a maximum of 2
seconds, allowing your right foot to be
moved easily from the brake pedal to
the accelerator. When the 2 seconds
have elapsed, without starting, the
system is automatically deactivated,
gradually releasing the braking
pressure. During this release stage, the
typical brake disengagement noise
indicating that the vehicle is going to
move imminently will be heard.
Fault warnings
System failure is indicated by
instrument panel warning light
with
digital display and warning light on
the instrument panel with multifunction
display (for versions/markets, where
provided) (see section “Warning lights
and messages” in the "Knowing the
instrument panel" chapter).
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
Regulation)
(for versions/markets, where provided)
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, the ASR intervenes
automatically braking the wheel that
is slipping.
The action of the ASR system is
especially useful in the following
conditions:
slipping of the inner wheel round
bends due to dynamic variations in the
load of excessive acceleration;
excessive power transmitted to the
wheels, also in relation to road surface
conditions;
acceleration on slippery, snowy or
icy road surfaces;
in the case of loss of grip on a wet
surface (aquaplaning).
43) 44) 45) 46)
MSR SYSTEM (engine
drive regulation)
This is an integral part of the ESC
system that, in the event of a sudden
gear down shift or an ABS braking,
cuts in and provides torque to the
engine thus preventing excessive
driving wheel drive which, especially in
poor grip conditions, can lead to a
loss of stability.
Turning the ASR system on/off
The ASR comes on automatically
whenever the engine is started.
When travelling, the ASR system can
be switched off and on again pressing
button fig. 71 located among the
controls in the instrument panel.
Switching off is shown by the warning
light
on the instrument panel
switching on together with a message
shown in the multifunction display,
for versions/markets where provided.
If the ASR is switched off while driving,
it is automatically switched on again
when the car 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 drive wheels skidding when setting
off gives you better traction.
