2007 FIAT SEICENTO fuel consumption

27GETTING TO KNOW YOUR CAR
ENGINE CONTROL
SYSTEM FAILURE
(EOBD) (amber)
In normal conditions, the warning
light will come on when the ignition
key is turned to MARand should go
out as soon as the engine is started.
The initial lighting up shows that the
warning light is working properly.
If the warning light either stays on or
comes on while travelling:
1. Fixed light- warning of a fuel
feed/ignition system failure which may
increase emissions in exhaust or cause
possible drops in performance, poor
handling and high consumption.
In such conditions, you can continue
driving but you should not tax the en-
gine and you should moderate the
speed. Prolonged use with the warn-
ing light on can cause damage. Con-
tact a Fiat Dealershipas soon as
possible.
The warning light will go out when
the failure disappears. In any case, the
system will store the error.
U
2. Flashing- warning that the catal-
yser can be damaged (see
EOBD SYSTEM
in this chapter).
If the warning light starts flashing, re-
lease the accelerator pedal and slow
the engine until the warning light stops
flashing. Continue driving at moderate
speed, preventing the warning light
from coming on again. Contact a Fiat
Dealershipas soon as possible.
Contact a Fiat Dealer-
ship as soon as possible if
the
Uwarning light ei-
ther does not come on when the
key is turned to MAR or comes
on, with fixed or flashing light,
when travelling.
FIAT CODE
(amber)
The warning light will
come on the three cases when the
key is at MAR:
1.Single flash - indicates that the
key code has been recognised. The
engine can be started.
2.Fixed light - the key code has not
been recognised. Follow the emer-
gency procedure to start the engine
(see
IN AN EMERGENCY).
3.Flashing light - indicates that the
car is not protected by the immo-
biliser system. The engine can how-
ever be started.

77DRIVING YOUR CAR
– do not remain stationary in deep
snow with the engine running: the
snow could deviate the exhaust gas
into the passenger compartment.
DRIVING WITH ABS
ABS is a braking system that essen-
tially offers two advantages:
1)it prevents wheel lock-up and
consequent skidding in emergency
stops, particularly when the road does
not offer much grip;
2)it makes it possible to brake and
steer at the same time so you can
avoid unexpected obstacles and direct
the car where you want while braking.
The extent to which this can be done
will depend on the physical limits of
the tyre’s sideways grip.To get the most out of ABS:
– during emergency conditions or
when grip conditions are poor, you
will feel a slight pulsation on the brake
pedal. This is the sign that the ABS is
working. Do not release the brake
pedal but continue to press so as not
to interrupt the braking action;
– ABS prevents the wheels from
locking, but it does not increase actual
grip conditions between tyre and
road. Therefore, even if your car is fit-
ted with ABS, respect the safety dis-
tance from the car in front of you and
keep your speed down when driving
into bends;
– ABS serves to increase the con-
trollability of the car, not to enable
you to go faster.CONTAINING
RUNNING COSTS
AND POLLUTION
Some suggestions which may help
you to keep the running costs of the
vehicle down and lower the amount
of toxic emissions released into the
atmosphere are given below.
GENERAL
CONSIDERATIONS
Car maintenance
The overall state of the car is an im-
portant factor which has a marked in-
fluence over fuel consumption and
driving comfort and on the life span of
your car. For this reason care should
be taken to maintain your car by car-
rying out the necessary checks and
regulations in accordance with the
specifications given in the
SERVICE
SCHEDULE
(see sections: SPARK PLUGS,
IDLING, AIR CLEANERS, TIMING).

78DRIVING YOUR CAR
Tyres
Tyre pressure should be checked at
least once every four weeks: if the
pressure is too low fuel consumption
increases as the resistance to the
rolling movement of the tyre is
greater. In this state, tyre wear is in-
creased and vehicle handling suffers
which will effect safety.
Unnecessary loads
Do not travel with too much luggage
stowed in the boot. The weight of the
vehicle and its trim greatly effects con-
sumption and stability.
Roof rack/ski rack
Remove roof racks and ski racks
from the roof of the car as soon as
they are no longer needed. These ac-
cessories reduce the aerodynamic
penetration of the vehicle and will in-
crease consumption. When having to
transport particularly large loads it is
better to use a trailer.Electric devices
Use electric devices for the neces-
sary time only. The heated rear win-
dow, fog lights, windscreen wipers,
heating system blower require large
amounts of electricity, and as a con-
sequence, the fuel consumption in-
creases (up to +25% in town).
Climate control system
The climate control system is a fur-
ther drag on the engine causing higher
fuel consumption (on average, up to
20%). When outside temperatures
permit, use the vents.
Aerodynamic accessories
The use of aerodynamic accessories
not certified for that specific purpose
can diminish the car’s aerodynamic
penetration and increase consump-
tion.BEHIND THE WHEEL
Starting-up
Do not warm up the engine when
the car is stationary, neither by idling
nor revving up. If you do, the engine
will warm up much more slowly and
increase fuel consumption and emis-
sions. It is therefore better to start
slowly and to keep the engine speed
down.
Unnecessary manoeuvres
Do not give quick bursts on the ac-
celerator when waiting at the traffic
lights or before turning off the engine.
This type of action, like the “double
clutch” are absolutely useless on mod-
ern cars. They only increase fuel con-
sumption and pollution.
Gear selection
As soon as traffic conditions allow,
shift up to a higher gear. Using a low
gear to have a sharp acceleration in-
creases the consumption. Likewise,
using a high gear when this is not
called for increases consumption,
emissions and wear on the engine.

79DRIVING YOUR CAR
Top speed
As speed increases, so does the fuel
consumption: note that passing from
90 to 120 km/h increases consump-
tion by about +30%. Keep your speed
as steady as possible and avoid un-
necessary braking and accelerations
that cost fuel and increase emissions
considerably. It is better to drive
“smoothly” trying to foresee the ma-
noeuvres to avoid imminent dangers
and always respect the safety distance
to avoid the need to slow down sud-
denly.
Acceleration
Sudden and sharp accelerations
revving up the engine increase con-
sumption and emissions; accelerate
gradually and do not exceed the max-
imum torque.USE
Cold start
Short journeys and frequent cold
start-ups do not allow the engine to
reach the best running temperature.
As a result, consumption rises (from
+15 to +30% in town) and so do the
harmful emissions.
Traffic situations and road
conditions
Consumption rises in heavy traffic, in
traffic jams where it is constantly nec-
essary to shift to low gears or in big
cities with many traffic lights.
Also twisting roads, mountain roads
and rough road surfaces pay a heavy
toll on consumption.
Hold-ups in traffic
During hold-ups (e.g.: level crossings)
switch off the engine.CHEAP RUNNING
THAT RESPECTS
THE ENVIRONMENT
Environmental protection has been
one of the guiding principles in the
production of Fiat 600. It is no acci-
dent that its pollution control equip-
ment is much more effective than that
required by current legislation.
Nonetheless, the environment can-
not get by without a concerted effort
from everyone.
By following a few simple rules you
can avoid harming the environment
and often cut down fuel consumption
at the same time.
On this subject, a few useful tips
have been given below to supplement
those marked by symbol #, at various
points of the handbook.
You are asked to read both the for-
mer and the latter carefully.

142TECHNICAL SPECIFICATIONS
CO2EMISSIONS
The fuel consumption values shown
in the table below were defined ac-
cording to the type-approval specifi-
cations in European Directives.
Consumption values are defined by
means of the following procedures:
– an urban cycle: consisting of a
cold start and a simulated drive in city
streets;
– an extra-urban cycle: consisting
in frequent accelerations, in all gears,
simulating normal conditions of use.
Speed ranges from 0 to 120 km/h;
– average combined cyclecon-
sisting of 37% urban cycle and 63% ex-
tra-urban cycle.
FUEL CONSUMPTION

conditions, weather, general con-
ditions of the car, driving style,
fittings and accessories, use of

sumption rates which can be dif-
ferent from the values shown in
