FAILURE INDICATIONS
System failure is indicated by the turning
on of warning light *on the instrument
panel with digital display and warning light
áon the instrument panel with multi-
function display (where provided) (see
section “Warning lights and messages”).
IMPORANT 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 the first
speed.
For correct operation of the
ESP and ASR systems, the
tyres must absolutely be of the same
brand and type on all wheels, in per-
fect conditions and, above all, of
type, brand and size specified.
WARNINGAt pickup the ESP system control unit will
keep brake force on wheels until reaching
the torque suitable for starting, or in any
case for max. 2 seconds in order to pass
easily from the brake pedal to the accel-
erator pedal.
After two seconds without starting, the
system will deactivate automatically by re-
leasing gradually the brake force.
At releasing, the typical brake disengage-
ment noise indicating that the car is go-
ing to move will be heard.

MSR system (engine braking
torque control)
It is an integral part of the ASR system that
in case of sudden gear shifting, cuts in pro-
viding torque to the engine thus prevent-
ing excessive driving wheel drive that, spe-
cially in poor grip conditions, can lead to
loss of stability.
Switching the systemon/off fig. 96
The ASR system switches on automatically
each time the engine is started.
When travelling, the ASR can be switched
off and on again pressing button Aset on
the dashboard fig. 96.
fig. 96F0M078Ab
When the ASR is switched off this is
shown by the lighting up of the led on the
button and by relevant message on the
multifunction display, where provided.
If the ASR is switched off when travelling,
it will turn on again automatically the next
time the engine is started.
When travelling on snowy roads with
snow chains, it may be helpful to turn the
ASR off: in fact, in these conditions, slip-
ping of the driving wheels when moving off
makes it possible to obtain better drive.

SPORT BOOST
The vehicle is equipped with a system al-
lowing to choose between two driving
modes: normal and sporting.
Pressing the SPORT BOOST button fig.
98sporting drive will be selected. This
type of drive is featured by major accel-
eration readiness and higher effort re-
quired on the steering-wheel for a suitable
drive control and feeling.
Moreover, pressing the SPORT BOOST
button the overboost function will be
started.
Switching this function on, the engine’s
electronic control unit allows, based on
the accelerator foot pedal’s position and
for a limited time, to reach maximum
pressure level within the supercharger
and, as a consequence, to increase the en-
gine torque in respect to the normal
achievable value.
This function is particularly useful in case
maximum performance is required for a
short time (for example in phase of over-
taking).
When the SPORT BOOST is on, the mes-
sage “SPORT” will be displayed on the in-
strument panel’s display. Press the rele-
vant button again to switch off the SPORT
BOOST and reset normal driving mode. IMPORTANT While parking and exe-
cuting a higher number of steering ma-
neuvers, steering may get harder; this is
normal as due to the intervention of the
system protecting the electrical engine
from overheating and therefore no repair
operation is required. Once the maneu-
ver is completed, power steering will be
working normally again.
Acceleration
Sudden acceleration is extremely disad-
vantageous in terms of consumption and
emissions: gradually and smoothly accel-
erate to contain consumption.
Using the SPORT BOOST, consumption
is slightly higher than the standard de-
clared values.
IMPORTANT Pressing the SPORT BOOST
button, the function takes nearly 5 seconds
to start.
IMPORTANT In phase of acceleration,
with SPORT BOOST on, it is possible to
experience jerks in driving as this is char-
acteristic of sporting drive.
