wheel torque FIAT PANDA 2009 169 / 2.G Owners Manual

If the space-saver wheel is used, the ESP
system keeps operating. Always remind
that the space-saver wheel, being smaller than
the original wheel provides less grip.
WARNING
For the correct operation of the ESP and
ASR systems, the tyres must absolutely be
the same make and type on all wheels, in perfect
conditions and, above all, of the type, make
and size specified.
WARNING
ASR SYSTEM (Antislip Regulation)
This is integral part of the ESP system and controls the car,
intervening automatically automatically every time one or
both driving wheels slip.
Depending on the slipping conditions, two different con-
trol systems are activated:❒
if the slipping involves both drive wheels, the ASR func-
tion intervenes by reducing the power transmitted by the
engine;
❒
if the slipping involves only one driving wheel, the ASR
system cuts in automatically braking the wheel that is
slipping.
❒
downhill: car at a standstill on a road with a gradient
higher than 2%, engine running, clutch and brake pedal
pressed and reverse gear engaged.
At pickup, the ESP system control unit will keep braking
pressure on the wheels until reaching the required torque
for starting or, in any case, for a maximum of 2 seconds
in order to move easily the right foot from the brake ped-
al to the accelerator pedal.
When two seconds have elapsed, without starting, the sys-
tem is automatically deactivated, gradually releasing the
braking pressure. During this release stage, the typical me-
chanical brake release noise can be heard, indicating that
the car is about to move.
Failure indications
A possible system failure is indicated by the *warning
light on the instrument panel – together with the dedicated
message in the reconfigurable 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, never leave the car without having
engaged the handbrake, turned the engine off and engaged
first gear.

When the ASR is switched off whilst driving, the next time
the car is started up the ASR is automatically switched
on by the system. When travelling on snowy roads with
snow chains, it may be helpful to turn the ASR off: in fact,
in these conditions, slipping of the drive wheels when mov-
ing off makes it possible to obtain better traction. The action of the ASR system is particularly helpful in
the following circumstances:
❒
slipping of the inner wheel when cornering due to the
effect of dynamic load changes or excessive accelera-
tion;
❒
too much power transmitted to the wheels also in re-
lation to the conditions of the road surface;
❒
acceleration on slippery, snowy or icy surfaces;
❒
in the event of loss of grip on a wet surface
(aquaplaning).
MSR system (engine drive regulation)
This is 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 dri-
ve which, especially in poor grip conditions, can lead to
loss of stability.
Switching the ASR system on/off fig. 88
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 press-
ing the C ASR OFF button. When the system is switched
on, this is signalled by a message on the reconfigurable mul-
tifunction display (where provided).
When the system is switched off, this is signalled by
the LED on the ASR OFF button lighting up and by a mes-
sage on the reconfigurable multifunction display (for ver-
sions/markets where provided).
Do not take unnecessary risks, even if your
vehicle is fitted with this system. Your dri-
ving style must always be suited to the road con-
ditions, visibility and traffic. The driver is ulti-
mately responsible for road safety.
