2010 FIAT PUNTO EVO Engine fault

INSTRUMENTS
Instrument background colour and type may vary ac-
cording to the version.
SPEEDOMETER fig. 14
This shows the speed of the vehicle.
REV COUNTER fig. 15
The rev counter shows the number of engine revolutions
per minute.
IMPORTANT The electronic injection control system
gradually shuts off the flow of fuel when the engine is over-
revving, resulting in a gradual loss of engine power.
When the engine is idling, the rev counter may indicate a
gradual or sudden increase of the rate.
This is normal and does not indicate a fault. It may becaused, for example, by the operation of the climate con-
trol system or fan. In these cases, a slow change in revs is
used to protect the battery charge.
FUEL GAUGE fig. 16
This shows the amount of fuel left in the tank.
E tank empty.
F tank full.
The reserve warning light A comes on to indicate that
approximately 7 litres of fuel are left in the tank.
Do not travel with the fuel tank almost empty: the gaps
in fuel delivery could damage the catalyst.
See the description in the “Refuelling” paragraph.
IMPORTANT The needle will point to E and warning light
A will blink to indicate a fault in the system. If this is the
case, go to a Fiat Dealership to have the system checked.

“Smart washing” function
Pull the stalk towards the steering wheel (temporary po-
sition) to operate the windscreen washer.
Keeping the stalk pulled for more than half a second, with
just one movement it is possible to operate the washer jet
and the wiper at the same time.
The wiper stops working three strokes after releasing the
stalk. A further stroke 6 seconds later completes the wip-
ing operation.RAIN SENSOR
(for versions/markets where provided)
The rain sensor is located behind the rear-view mirror in
contact with the windscreen and has the purpose of au-
tomatically adjusting the frequency of the windscreen wiper
strokes depending on the intensity of the rain during in-
termittent operation.
IMPORTANT Keep the glass in the sensor area clean.
Activation
Move the twist switch on the right-hand stalk to
≤fig.
51. The activation of the sensor is signalled by a wiper
stroke. Through the setup menu it is possible to increase
the sensitivity of the rain sensor. The increasing of the rain
sensor sensitivity is also signalled by a stroke of the wipers.
If the windscreen washer is used with the rain sensor ac-
tivated, the normal washing cycle is performed, after which
the rain sensor resumes its normal automatic operation.
Deactivation
Move the stalk twist switch away from
≤fig. 51 or turn
the ignition key to STOP. When the engine is next start-
ed (key at MAR), the sensor will not be reactivated even
if the twist switch is still at
≤fig. 51. To activate the rain
sensor, you have to move the twist switch from
≤to an-
other position and then back to
≤. Rain sensor activa-
tion will be indicated by at least one wiper stroke, even if
the windscreen is dry.

Do not use the windscreen wipers to re-
move layers of snow or ice from the wind-
screen. In such conditions, the windscreen
wipers may be subjected to excessive stress,
prompting intervention from the motor protection
which prevents operation for a few seconds. If op-
eration is not restored, even after turning the key
and restarting the engine, go to a Fiat Dealership.
When released, the stalk returns to its default position and
the wipers automatically switch off.
With the twist switch at
≤, the windscreen wiper will
automatically adapt to the speed of the car.
IMPORTANT Replace the wiper blades as specified in the
“Maintenance and care” section.

EOBD SYSTEM
The EOBD system (European On Board Diagnosis) pro-
vides a continuous diagnosis of the car’s emission-related
components.
It also alerts the driver, by way of warning light Ulight-
ing up on the instrument panel (together with the relevant
message on the multifunction display, where provided) (see
section “Warning lights and messages”), when these com-
ponents are no longer in peak condition.
The goal of the system is to:
❒keep the system efficiency under control;
❒warn when a fault causes emissions levels to increase;
❒warn of the need to replace non-performing compo-
nents.
The system also has a connector that can be interfaced
with appropriate equipment, which makes it possible to
read the error codes stored in the control unit, together
with a series of specific parameters for engine operation
and diagnosis. This check can also be carried out by traf-
fic police.
IMPORTANT After eliminating the problem, to check the
system completely, Fiat Dealerships run a bench test and,
if necessary, road tests which may also call for a long jour-
ney.

IMPORTANT NOTES ABOUT THE TPMS
SYSTEM
The fault indications are not stored and will therefore not
be displayed after the engine has been switched off and
then on again. If the fault conditions persist, the control
unit will send the relative indications to the instrument
panel only after the vehicle has been in motion for a short
time.
WARNING Particularly strong radio frequency interference
may cause the TPMS system to function incorrectly. This
condition is indicated to the driver by a message on the dis-
play. The warning message will go off automatically as soon
as the interference stops disturbing the system.

CONTENTS
The presence of TPMS does not exoner-
ate the driver from regularly checking the
pressure of the tyres and the spare wheel (see
“Wheels” in the “Maintenance and care” section).
WARNING
The TPMS is not able to warn you of sud-
den tyre pressure losses (for example when
a tyre bursts). In this case, stop the car, braking
with care and avoiding sharp steering actions.
WARNING
Replacing the normal tyres with winter
tyres and vice versa requires an inspection
of the TPMS, which should be carried out only
by a Fiat Dealership.
WARNING
The TPMS requires the use of specific
equipment. Contact a Fiat Dealership to
find out which accessories are compatible with the
system (wheels, hub caps etc.). Using other ac-
cessories may hinder the normal operation of the
system.
WARNING
Changes in outside temperature may
cause tyre pressures to vary. The TPMS
system may temporarily indicate insufficient pres-
sure. In this case, check the tyre pressures with the
tyres cold and, if necessary, pump them up.

ACCESSORIES PURCHASED
BY THE OWNER
If, after buying the vehicle, you decide to install electrical
accessories that require a permanent electrical supply
(sound system, satellite anti-theft system, etc.) or ones that
drain the battery, contact a Fiat Dealership, whose quali-
fied personnel, besides suggesting the most suitable de-
vices from Lineaccessori Fiat, will also check whether the
vehicle’s electrics are able to withstand the load required,
or whether they need to be integrated with a more pow-
erful battery.
Take care when fitting additional spoilers,
alloy wheels or non-standard wheel hubs:
they could reduce the ventilation of the brakes
and affect efficiency under sharp, repeated brak-
ing or on long descents. Make sure that nothing
obstructs the pedals (mats, etc.)
WARNING
INSTALLING ELECTRICAL/ELECTRONIC
DEVICES
Electrical and electronic devices installed after buying the
car in the context of after-sales service must carry the fol-
lowing label:
Fiat Auto S.p.A. authorises the installation of transceiving
devices provided that they are installed by a specialised
centre according to rules of good engineering practice in
compliance with the manufacturer’s instructions.
IMPORTANT Traffic police may not allow the car on the
road if devices have been installed which modify the features
of the car. This may also cause invalidation of warranty in
relation to faults caused by the change or either directly
or indirectly related to it.
Fiat Auto S.p.A. shall not be liable for damage caused by
the installation of accessories either not supplied or rec-
ommended by Fiat Auto S.p.A. and/or not installed in com-
pliance with the provided instructions.
RADIOTRANSMITTERS AND MOBILE
PHONES
Radio transmitter equipment (vehicle mobile phones, CB
radios, amateur radio etc.) shall not be used inside the
car unless a separate aerial is mounted on the roof.
IMPORTANT The use of these devices inside the pas-
senger compartment (without a separate aerial) may cause
the vehicle electrical systems to malfunction. This could
compromise safety in addition to constituting a potential
hazard for passengers’ health.
In addition, transmission and reception of these devices
may be affected by the shielding effect of the car body.
As far as the use of EC-approved mobile phones is con-
cerned (GSM, GPRS, UMTS), follow the instructions for
use provided by the mobile phone manufacturer.

DIESEL PARTICULATE FILTER (DPF)
(for versions/markets where provided)
The Diesel Particulate Filter is a mechanical filter, inte-
gral to the exhaust system, that physically traps particu-
lates present in the exhaust gases of diesel engines.
It is needed to eliminate almost all particulates in compli-
ance with current/future legislation.
During normal use of the vehicle, the engine control unit
records a set of data (e.g. travel time, type of route, tem-
peratures, etc.) and it will then calculate how much par-
ticulate has been trapped by the filter.
Since this filter physically traps particulate, it should be re-
generated (cleaned) at regular intervals by burning the car-
bon particles.
The regeneration procedure is handled automatically by
the engine control unit according to the filter conditions
and vehicle use conditions.
During regeneration, the following may occur: a limited in-
crease in the engine speed, activation of the fan, a limited
increase in fumes and high temperatures at the exhaust.
These are not faults; they do not impair vehicle perfor-
mance or damage the environment.
If the dedicated message is displayed, refer to the “Warn-
ing lights and messages” section.
The diesel particulate filter (DPF) (for ver-
sions/markets where required) reaches
high temperatures during normal operation.
Therefore do not therefore park the vehicle on in-
flammable materials (grass, dry leaves, pine nee-
dles, etc.): fire hazard.
WARNING
The catalytic converter also reaches high
temperatures during normal operation.
Do not park the vehicle on grass, dry leaves, pine
needles or other flammable material: fire hazard.
