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. 125
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.

AND CONTROLS
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 European On Board Diagnostic sys-
tem (EOBD), fitted to engine electronic
control units, allows monitoring and warn-
ing of any malfunction to the electronic
systems that could increase exhaust emis-
sions.
The objective is:
❒To keep system efficiency under con-
trol;
❒Warn when a fault causes emission lev-
els to increase;
❒Warn of the need to replace deterio-
rated components.
This diagnostic system indicates the pres-
ence of deteriorated components or sys-
tem malfunctioning (see section “Warn-
ing lights and messages”) by the turning on
of the instrument panel warning light U
(together with the message on the dis-
play).
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.

NOTE The car is provided with a diag-
nostic connector that can be interfaced
with appropriate tools, which makes it
possible to read the error codes stored in
the control units, together with a series of
specific parameters for engine operation
and diagnosis. This test can also be per-
formed by traffic controller agents.
IMPORTANT: After a servicing operation
at Fiat Dealership aimed to eliminate mal-
functioning connected to the EOBD sys-
tem, in order to check the system thor-
oughly it could be required to run a bench
test and, if necessary, road tests which
may also call for a long journey.TYRE PRESSURE
MONITORING SYSTEM
- T.P.M.S. (where
provided)
The car can be equipped with the T.P.M.S.
(Tyre Pressure Monitoring System). This
system consists of a radio-frequency sen-
sor, installed on each wheel (on the rim
inside the tyre) that sends pressure infor-
mation to the control unit.
IMPORTANT System control unit moni-
tors the pressure of the four car tyres but
not the space-saver spare wheel. It is
therefore recommended to always check
also the space-saver spare wheel pressure.
IMPORTANT Pay the utmost attention
when checking or inflating tyres. Excessive
pressure impairs road holding, increases
suspension and wheel stress and causes
abnormal tyre wear.IMPORTANT Tyre pressure should be
checked with tyres rested and cold.
Should it become necessary for whatev-
er reason to check pressure with hot
tyres, do not reduce pressure although it
is higher than the prescribed value but re-
peat the check when tyres are cold.
The T.P.M.S. system does not
exempt the driver to check
tyre and space-saver spare wheel pres-
sure at regular intervals.

IMPORTANT NOTES ABOUT
THE T.P.M.S. SYSTEM
Failure indications will not be stored and
therefore will not be displayed when turn-
ing the engine off and on again. If failure
persists, the control unit will send warn-
ing indications to the instrument panel on-
ly after a few seconds when the car is
moving.
IMPORTANT T.P.M.S. system cannot in-
dicate sudden tyre pressure drops (e.g.:
tyre burst). In this event, brake the car
cautiously and avoid sudden steering.
IMPORTANT Replacing standard tyres
with winter tyres and vice versa involves
T.P.M.S. system set-up that shall be per-
formed at Fiat Dealerships only.
IMPORTANT The T.P.M.S. system re-
quires special equipment. Consult Fiat
Dealership to know what type of acces-
sories are compatible with the system
(wheels, wheel caps, etc.). Using other ac-
cessories could cause system malfunc-
tioning.IMPORTANT Tyre pressure could change
according to outside temperature. For this
reason the T.P.M.S. system could tem-
porarily indicate low tyre pressure. In this
event check pressure with cold tyres and
restore proper inflation values if required.
IMPORTANT If the car is fitted with
T.P.M.S. system, tyre and/or rim removal
and refitting operations involve special
precautions; to prevent damages or wrong
sensor refitting, contact Fiat Dealership to
have tyre and/or rim changed.
IMPORTANT If the car is fitted with
T.P.M.S. system, when changing a tyre,
change also the rubber seal of the valve.
Contact a Fiat Dealership.
IMPORTANT Strong radiofrequency
noise may inhibit regular TPMS system op-
eration; in this event, a dedicated message
will be displayed to warn the driver. This
message will disappear automatically as
soon as noise disappears.SOUND SYSTEM
(where provided)
For the operation of the radio with
CD/MP3 CD (where provided), read the
instructions for use given in the Supple-
ment attached to the Owner Handbook.
SOUND SYSTEM
(where provided)
The system includes:
❒2 tweeters (power 40W max. each),
located on front doors;
❒2 mid-woofers, (diameter 165 mm,
power 40W max. each), located on
front doors;
❒2 full-range speakers, (diameter 165
mm, power 40W max. each), located
on rear doors.

Roof rack/ski rack
Remove the roof rack or the ski rack from
the roof as soon as they are no longer
used. These accessories lower air pene-
tration and adversely affect consumption
levels. When needing to carry particular-
ly voluminous objects, preferably use a
trailer.
Electric devices
Use electric devices only for the amount
of time needed. Rear heated window, ad-
ditional headlights, windscreen wipers and
heater fan need a considerable amount of
energy, therefore increasing the require-
ment of current increases fuel consump-
tion (up to +25% in the urban cycle).
Climate control
The air conditioner is an additional load
which greatly affects the engine leading to
higher consumption (on average up to
+20%). When the temperature outside
the car permits it, use the air vents where
possible.
Spoilers
The use of non-certified aerodynamic
items may adversely affect air drag and
consumption levels.DRIVING STYLE
Starting
Do not warm the engine with the car at
a standstill or at idle or high speed: under
these conditions the engine warms up
much more slowly, increasing electrical
consumption and emissions. It is therefore
advisable to move off immediately, slow-
ly, avoiding high speeds. This way the en-
gine will warm faster.
Unnecessary actions
Avoid accelerating when waiting at traffic
lights or before switching off the engine.
This and also double declutching is ab-
solutely pointless on modern cars and al-
so increase consumption and pollution.
Gear selection
As soon as the conditions of the traffic and
road allow, use a higher gear. Using a low
gear to obtain brilliant performance in-
creases consumption.
In the same way improper use of a high
gear increases consumption, emissions an
engine wear.CONTAINING
RUNNING COSTS
Here are some suggestions which may
help you to keep the running costs of your
car down and lower the amount of toxic
emissions released into the atmosphere.
GENERAL CONSIDERATIONS
Car maintenance
Have checks and adjustments carried out
in accordance with the “Service schedule”.
Tyres
Check the pressure of the tyres routine-
ly at an interval of no more than 4 weeks:
if the pressure is too low, consumption
levels increase as resistance to rolling is
higher.
Unnecessary loads
Do not travel with too much luggage
stowed in the boot. The weight of the car
(especially when driving in town) and its
trim greatly affects consumption and sta-
bility.

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.

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.
