ASR FUNCTION (ANTISLIP
REGULATION): GENERALThe ASR system integrates the VDC sys-
tem controlling the vehicle drive and com-
ing into operation automatically each time
one or both driving wheels skid.
Two different control systems are activated,
depending on the skidding conditions:
– If skidding concerns both driving wheels,
because it is caused by the excessive power
transmitted, the ASR system cuts in reduc-
ing the power transmitted by the engine.
– If skidding concerns only one driving
wheel, the ASR system cuts in automatically
braking the skidding wheel, with an effect
similar to that of a self-locking differential.The action of the ASR system is particularly
helpful under the following conditions:
– Skidding of the inner wheel on a bend,
due to the effect of the dynamic changes of
the load or over-accelerating.
– Excessive power transmitted to the
wheels, also in relation to the conditions of
the road surface.
– Acceleration on slippery, snowy or icy
surfaces.
– In the case of loss of grip on a wet sur-
face (aquaplaning).
CUTTING IN OF THE VDC
SYSTEMThe cutting in of the VDC system is indi-
cated by the flashing of the warning lightá
on the instrument cluster, to inform the
driver that the car is in critical conditions of
stability and grip.
TURNING ON THE ASR
FUNCTIONThe ASR function turns on automatically
each time the engine is started.
When travelling it is possible to switch the
system off and on again pressing the switch
(A-fig. 171
) on the centre console.
Function disconnection is shown by the led
on the ASR button being turned on. If the
function is turned off while travelling, it will
turn on again automatically the next time
the engine is started.
WARNING When driving on snow, with
snow chains fitted, if may be helpful to switch
off the ASR function: in these conditions in
fact, skidding of the driving wheels when
moving off helps to obtain better traction.

CORRECT USE OF THE CAR

DRIVING IN THE RAINRain and wet roads can be dangerous.
If the road is wet, the traction between
wheel and asphalt is greatly reduced, thus
increasing the stopping distance and de-
creasing road holding.
Here are few suggestions in the case of
rain:
– Reduce speed and keep further back
from the vehicle in front.
– If it is raining particularly heavily, visi-
bility is also reduced. In these cases, switch
on the dipped headlights even if it is still day-
light so you can be seen more easily.
– Do not drive through puddles at speed
and hold on tightly to the wheel if you do: a
puddle taken at high speed might cause you
to lose control of the car (“aquaplaning”).
– Position the ventilation controls for
demisting (see chapter “Getting to know
your car”), to prevent visibility from wors-
ening.
– Routinely check the conditions of the
windscreen wiper blades.
DRIVING IN THE FOG– If fog is very thick, avoid travelling
where possible. If travelling with mist,
ground fog or the possibility of fog banks:
– Drive at moderate speed.
– Also in the day turn on the dipped-beam
headlights, rear fog guards and front fog
lights. Do not use the main beam headlights.
WARNINGOn stretches of road with
good visibility, switch off your rear foglights;
the brightness of these lights could annoy
the people travelling in the cars behind.
– Remember that fog also involves wet
asphalt, thus greater difficulty in all types of
manoeuvres and longer stopping distances.
– Keep well away from the vehicle in
front.
– Where possible avoid sudden changes
in speed.
– Possibly avoid overtaking other vehicles.
– If the vehicle is forced to stop (faults,
impossibility to continue due to poor visi-
bility, etc.), firstly try to pull off the road.
Then turn on the hazard warning lights and,
if possible the dipped beam headlights. Ry-
thmically sound the horn if you note another
car coming.
MOUNTAIN DRIVING– When driving downhill, use the engine
braking by engaging a low gear, to prevent
the brakes from overheating.
– Never coast downhill with the engine off
or in neutral and especially not with the ig-
nition key removed.
– Drive at moderate speed and avoid “cut-
ting” corners.
– Remember that overtaking up hill is
slower and therefore requires a greater
length of clear road. If you are being over-
taken on a hill, move over to enable the
other vehicle to pass in safety.
