2014 FIAT BRAVO engine

ASR SYSTEM (Antislip Regulation)
This is integral to the ESP system and automatically
intervenes if one or both drive wheels slip, helping
the driver to control the car.
Depending on the slipping conditions, two different
control systems are activated:
❒if the slipping involves both drive wheels, the ASR
intervenes reducing the power transmitted by the
engine;
❒if the slipping only involves one of the drive
wheels, the ASR intervenes automatically braking
the wheel that is slipping.
The action of the ASR system is particularly helpful
in the following circumstances:
❒slipping of the inner wheel on bends due to
dynamic variations in the load or excessive
acceleration;
❒excessive power transmitted to the wheels, also in
relation to road surface conditions;
❒acceleration on slippery, snowy or icy road
surfaces;
❒loss of grip on wet road surfaces (aquaplaning).
MSR SYSTEM (ENGINE DRIVE
REGULATION)
This is an integral part of the ASR system that, in the
event of a sudden gear downshifting, cuts in and
provides torque to the engine thus preventing
excessive drive wheel drive which, especially in poor
grip conditions, can lead to loss of stability.ENGAGEMENT/DISENGAGEMENT OF THE
ASR SYSTEM
The ASR system switches on automatically each time
the engine is started.
When the system is active, a message is shown on
the display (see “Warning lights and messages”
chapter).
Whilst driving, the ASR can be deactivated and
subsequently activated again by pressing the ASR
OFF button on the dashboard, next to the steering
wheel.
Whilst driving, the ASR can be switched off and
subsequently switched on again by pressing button C.

EOBD SYSTEMThe EOBD system (European On Board Diagnostic)
is a diagnosis system installed on the ECUs, which
detects and reports possible malfunctions in the
electronic systems that could worsen emissions.
The goal of the system is to:
❒monitor the system efficiency;
❒indicate an increase in emissions due to vehicle
malfunction;
❒indicate the need to replace components which
have deteriorated.
It also alerts the driver, by turning on the warning
light
on the instrument panel (together with
relevant message on the display), when these
components are damaged; it can also report any
system malfunctions (see "Warning lights and
messages" chapter).
Note The car also has a connector that can be
interfaced with appropriate tools, which makes it
possible to read the error codes stored in the
electronic control units together with a series of
specific parameters for engine operation and
diagnosis. This check can also be carried out by the
traffic police.
IMPORTANT After an operation at the Fiat
Dealership, aimed at solving malfunctions linked to
the EOBD system, some bench tests should be
made, along with road tests if necessary, for a
complete check of the system. The latter may also
require the car to cover a long distance.
WIRING FOR RADIO SYSTEM(for versions/markets, where provided)
The car may be equipped with a storage
compartment on the dashboard.
The radio must be installed in the place occupied by
the central storage compartment A fig. 90, where
you will find the wiring.
Press on the retaining devices under the central
storage compartment to extract the compartment.
WARNING
For connection to the radio system
set-up, contact a Fiat Dealership
to prevent any problem that could impair car
safety.

RADIO TRANSMITTERS AND MOBILE
PHONES
Radio transmitter equipment (vehicle mobile phones,
CB radios etc.) cannot be used inside the car unless
a separate aerial is mounted externally.
IMPORTANT The use of these devices inside the
passenger compartment (without an external aerial)
may cause the electrical systems to malfunction.
This could compromise the safety of the car in
addition to constituting a potential hazard for
passengers' health.
In addition, transmission and reception of these
devices may be negatively affected by the shielding
effect of the car body. As far as the use of
EC-approved mobile phones is concerned (GSM,
GPRS, UMTS), follow the usage instructions provided
by the mobile phone manufacturer.
"DUALDRIVE" ELECTRIC POWER
STEERING SYSTEMThe car is equipped with an electrically controlled
power steering system called “Dualdrive”, working
only with the ignition key at MAR-ON and the
engine running, that customises steering force
according to the driving conditions.
IMPORTANT When turning the ignition key quickly,
full power steering functionality can be achieved after
1-2 seconds.
ACTIVATION/DEACTIVATION
(CITY function)
(for versions/markets, where provided)
To turn the function on/off, press button A fig. 92 on
the dashboard, next to the steering wheel.

The activation of the function is signalled by the
word CITY on the display (in some versions it is
signalled by the switching on of the warning light
CITY).
When the CITY function is on, the steering wheel
effort is lighter and parking operations are easier:
therefore this function is particularly useful for
driving in city centres.
FAILURE INDICATIONS
Any failure of the electric power steering system is
indicated by instrument panel warning light
coming
on together with a message on the display (on
some versions together with a symbol on the display)
(see “Warning lights and messages” chapter).
In the event of electric power steering system failure,
the car can be driven with mechanical steering.
SPORT FUNCTION
(for versions/markets, where provided)
The vehicle may be equipped with a system that
allows a choice between two styles of driving, normal
and sports.
Pressing the SPORT button fig. 93 produces a sporty
driving setting characterised by higher acceleration
response and more effort required at the steering
wheel for a sporty driving sensation.
Pressing the SPORT button also activates the
turbocharger supercharging function (overboost).Via this function the engine management control unit
allows - in relation to the position of the accelerator
pedal and for a limited time - maximum pressure
levels to be reached inside the turbocharger, with a
consequent increase in engine torque with respect to
that which is normally possible.
This function is particularly useful whenever
maximum performance is required for a short time
(e.g. when overtaking).
The letter S is lit up in the instrument panel display
when the function is switched on. Press the button
again to switch the function off and restore the
normal driving setting.

IMPORTANT When the SPORT button is pressed,
the function is activated about 5 seconds later.
IMPORTANT During acceleration, when the SPORT
function is used the steering may shudder which is
typical of a sports setting.
IMPORTANT During parking manoeuvres requiring a
lot of steering, the steering may become harder;
this is normal and is due to the intervention of the
system to protect the electric steering motor from
overheating; so, no intervention is required. When
the car is used again later on, the power steering will
work normally.Acceleration
Sudden acceleration has a very negative effect on fuel
consumption and emissions: accelerate gradually to
contain consumption.
When the SPORT function is used the consumption
figures will be slightly higher than those stated.
WARNING
Under no circumstances should
aftermarket operations involving
steering system or steering column
modifications (e.g.: installation of anti-theft
device) be carried out that could badly affect
performance and safety.This also causes the
warranty to become null and void and results in
vehicle non-compliance with type-approval
requirements.
WARNING
Before starting any servicing operation,
stop the engine and remove the key
from the ignition switch to operate the steering
lock, particularly when the wheels do not touch
the ground. If this is not possible (for example
if the key needs to be turned to MAR-ON or
the engine must be running), remove the main
fuse that protects the electric power steering.

TPMS (Tyre Pressure Monitoring
System)(for versions/markets, where provided)
The car may be fitted with a tyre pressure
monitoring system (TPMS), which informs the driver
of the tyre inflation status via the "Check tyre
pressure" and "Low tyre pressure" messages on the
display. For a detailed description of the two
messages, see the "Warning lights and messages"
chapter.
The system comprises a radio-frequency transmitter
fitted to each wheel (on the wheel rim inside the
tyre), which is able to send information on the tyre
inflation pressure of each wheel to the control unit.
WARNING
The presence of the TPMS does not
permit the driver to neglect regular
checking of the pressure of the tyres and the
spare wheel (see "Wheels" in the "Maintenance
and care" chapter).
WARNING
Sensor malfunctioning 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.Tyre pressure must be checked with tyres rested and
cold. Should it become necessary for whatever
reason to check pressure with warm tyres, do not
reduce pressure even though it is higher than the
prescribed value, but repeat the check when tyres
are cold (see "Wheels" in the "Technical data"
chapter).
The TPMS is not able to warn you of sudden tyre
pressure losses (for example when a tyre bursts). In
this case, stop the car, braking with caution and
avoiding abrupt steering.
Particularly strong radio-frequency interference may
cause the TPMS to function incorrectly. This
condition is indicated to the driver by a warning light
or symbol lighting up on the instrument panel
together with a dedicated message. The message will
disappear automatically as soon as the radio-
frequency interference ceases to affect the system.
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 accessories may hinder
the normal operation of the system. Given the
unique valve specifications, only use Fiat-approved
sealers to repair the tyres. The use of other sealers
may prevent the normal operation of the system.

For diesel engines, only use diesel fuel for
motor vehicles in accordance with EN 590
European specifications.The use of other
products or mixtures may damage the engine
beyond repair and consequently invalidate the
warranty, due to the damage caused. If you
accidentally refuel with another type of fuel, do
not start the engine, and drain the tank. If the
engine has been run for even an extremely
limited amount of time, you must not only drain
the fuel tank, but the rest of the supply circuit
as well.
REFUELLING CAPACITY
To fill the tank completely, top-up twice after the
first click of the fuel delivery gun. Further top-ups
could cause faults in the fuel feeding system.
FUEL FILLER CAP
Opening fig. 97
Open flap A pulling it outwards, hold cap B still,
insert the ignition key in the lock and turn it
anticlockwise.
Turn the cap anticlockwise and remove it. The cap
has a device C that attaches it to the flap so it
cannot be lost. When refilling, attach the cap to the
flap, as shown.Closing
Fit the cap (complete with key) and turn it clockwise
until it clicks once or more.
Turn the key clockwise and extract it, then close the
flap.
IMPORTANT The airtight sealing of the tank may
cause a slight vacuum. A suction noise when you
release the cap is therefore entirely normal.
WARNING
Do not bring naked flames or lit
cigarettes near to the fuel tank opening:
fire risk. Keep your face away from the fuel
filler to prevent breathing in harmful vapours.

PROTECTING THE ENVIRONMENTThe following devices are used for reducing diesel
fuel engine emissions:
❒oxidising catalytic converter
❒exhaust gas recirculation system (EGR)
❒particulate filter (DPF).
WARNING
Under normal operating conditions, the
silencer becomes very hot .Therefore
do not park the car on flammable materials
(grass, dry leaves, pine needles, etc .): fire
hazard.
DIESEL PARTICULATE FILTER (DPF)
(for versions/markets, where provided)
The Diesel Particulate Filter is a mechanical filter,
integral with the exhaust system, that physically traps
particulates present in the exhaust gases of diesel
engines. The diesel particulate filter has been
adopted to eliminate almost all particulates in
compliance with current / future legal regulations.
During normal use of the vehicle, the engine control
unit records a set of data (e.g.: travel time, type of
route, temperatures, etc.) and it will then calculate
how much particulate has been trapped by the filter.Since this filter physically traps particulate, it should
be regenerated (cleaned) at regular intervals by
burning the carbon particles. The regeneration
procedure is controlled automatically by the engine
management control unit according to the filter
conditions and vehicle use conditions. There may be
a limited increase in the engine speed during the
regeneration, a limited increase in fumes and high
temperatures at the exhaust. These are not faults;
they do not impair vehicle performance or damage
the environment.
Particulate filter clogged
If the warning light switches on on the instrument
panel (along with the message on the display) refer
to the "Warning lights and messages" chapter.
