ASR SYSTEM
(AntiSlip Regulator)
(where provided)
The ASR function controls car drive and
cuts in automatically every time one or
both driving wheels slip.
According to slipping conditions, two dif-
ferent control systems are activated:
❒if slipping involves both driving wheels,
the ASR function intervenes reducing
the power transmitted by the engine;
❒if slipping involves only one driving
wheel, the TC (Traction Control)
function cuts in automatically braking
the wheel that is slipping.
The action of the ASR is particularly help-
ful in the following circumstances:
❒slipping of the inner wheel due to the
effect of dynamic load changes or ex-
cessive acceleration;
❒too much power transmitted to the
wheels also in relation to the condi-
tions of the road surface;
❒acceleration on slippery, snowy or
frozen surfaces;
❒in the case of loss of grip on a wet sur-
face (aquaplaning).
SWITCHING THE ASR SYSTEM
ON/OFF fig. 122
The ASR system switches on automatically
each time the engine is started.
When travelling ASR can be switched off
and on again pressing switchAset aside
the gearshift lever.
When the ASR is switched off this is
shown by the lighting up of the led on the
switch and by the relevant message on the
display (see section “Warning lights and
messages”).
If the ASR is switched off when travelling,
it will turn on again automatically the next
time the engine is started.
During the use of the space-
saver spare wheel, the ESP
system carries on working. However,
you must remind that the space-saver
spare wheel has dimensions smaller
than the standard tyre and therefore
its grip is reduced as to the other car
tyres.
WARNING
For correct operation of the
ESP system, the tyres must
absolutely be of the same brand and
type on all wheels, in perfect condi-
tions and, above all, of type, brand
and size specified.

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.FAILURE INDICATIONS
In the event of malfunctioning, the ASR
system is automatically disconnected and
the warning light
áwill come on with
fixed light on the instrument together with
the message on the display (see section
“Warning lights and messages”). In this
case contact Fiat Dealership as soon as
possible.
EOBD SYSTEM
The EOBD system (European On Board
Diagnosis) allows continuous diagnosis of
the components of the car correlated with
emissions.
It also alerts the driver, by turning on the
warning light
Uon the instrument pan-
el (together with the message on the dis-
play) (see section “Warning lights and
messages”), when these conditions are no
longer in peak conditions.
The objective is:
❒to keep the system efficiency under
control;
❒warn when a fault causes emissions
levels to increase;
❒warn of the need to replace deterio-
rated components.
The system also has a diagnostic connec-
tor that can be interfaced with appropri-
ate tools, which makes it possible to read
the error codes stored in the control unit,
together with a series of specific parame-
ters for engine operation and diagnosis.
This check can also be carried out by the
traffic police.
The performance of the sys-
tem, in terms of active safe-
ty should not induce the driver to take
pointless and unnecessary risks. The
style of driving must in any case al-
ways be adapted to the conditions of
the road surface, visibility an traffic.
Road safety is always the driver’s re-
sponsibility.
WARNING
For correct operation of the
ASR system, the tyres must
absolutely be of the same brand and
type on all wheels, in perfect condi-
tions and, above all, of type, brand
and size specified.

IMPORTANT When snow tyres are used
with a max speed index below the one
that can be reached by the car (increased
by 5%), place a notice in the passenger’s
compartment, plainly in the driver’s view
which states the max permissible speed of
the snow tyres (as per EC Directive).
All four tyres should be the same (brand
and track) to ensure greater safety when
driving and braking and better driveabili-
ty.
Remember that it is inappropriate to
change the direction of rotation of tyres.SNOW TYRES
Use snow tyres of the same size as the
normal tyres provided with the car.
Fiat Dealership will be happy to provide
advice concerning the most suitable type
of tyre for the customer’s requirements.
For the type of tyre to be used, inflation
pressures and the specifications of snow
tyres, follow the instructions given in para-
graph “Wheels” in section “Technical
specifications”.
The winter features of these tyres are re-
duced considerably when the tread depth
is below 4 mm. In this case, they should
be replaced.
Due to the snow tyre features, under nor-
mal conditions of use or on long motor-
way journeys, the performance of these
tyres is lower than that of normal tyres. It
is therefore necessary to limit their use to
the purposes for which they are certified.

OF THE CAR
The max speed for snow
tyres with “Q” marking is
160 km/h; 190 km/h for tyres with “T”
marking and 210 km/h for tyres with
H marking. The Road Traffic Code
speed limits must however be always
strictly observed.
WARNING

SNOW CHAINS
Use of snow chains should be in compli-
ance with local regulations.
Snow chains should only be applied to the
driving wheels (front wheels). We rec-
ommend using Lineaccessori Fiat snow
chains.
Check the tension of the chains after the
first few metres have been driven.
IMPORTANT Snow chains cannot be fit-
ted to the space-saver spare wheel. So, if
a front (drive) wheel is punctured and
chains are needed, a rear wheel should be
fitted to the front of the car and the spare
wheel should be fitted to the rear. This
way with two normal drive wheels, snow
chains can be fitted to them to solve an
emergency.
IMPORTANT Snow chains shall only be
a temporary solution. Use snow tyres if
you have to travel for long on roadbeds
covered with snow or ice.
IMPORTANT With snow chains fitted,
use the accelerator with extreme care to
prevent or to reduce to a minimum dri-
ving wheel skidding in order to avoid snow
chain breaking that could cause damages
to the body or the mechanical parts of the
car.

Keep your speed down when snow chains are fitted. Do not ex-

also to drive for long distances on roads not covered with snow
to prevent damaging the car and the roadbed.
