Fiat 500 Owner's Handbook Manual page 64

When two seconds have elapsed, without starting,
the system is automatically deactivated, gradually
releasing the braking pressure. During this release
stage, the typical mechanical brake release noise can
be heard, indicating that the car is about to move.
HILL HOLDER SYSTEM FAILURE
INDICATIONS
A possible system failure is indicated by the
warning light on the instrument panel - together
with the dedicated message in the multifunction
display (for versions/markets, where provided) -
coming on (see "Warning lights and messages"
chapter).
IMPORTANT The Hill Holder system is not a parking
brake, therefore do not leave the car without
activating the handbrake, switching off the engine and
engaging first gear.
WARNING
If the space-saver wheel is used, the ESP
system keeps operating. Always
remember that the space-saver wheel, being
smaller than the original wheel provides less
grip. For the correct operation of the ESP and
ASR systems it is vital that the tyres are the
same make and the same type on all the
wheels, in perfect condition and, above all, the
prescribed type, make and size.
ASR SYSTEM (Antislip Regulation)
(for versions/markets, where provided)
This is integral to the ESP system and automatically
intervenes if one or both drive wheels slip, helping
the driver to control the car.
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 an integral part of the ASR system that, in the
event of a sudden gear downshifting, cuts in and
provides torque to the engine thus preventing
excessive drive wheel drive which, especially in poor
grip conditions, can lead to loss of stability.
ENGAGEMENT/DISENGAGEMENT OF THE
ASR SYSTEM
The ASR system switches on automatically each time
the engine is started.
