fuel consumption Alfa Romeo 159 2008 Owner handbook (in English)

Consumption
If the distance unit set is km (see pre-
vious paragraph) the display will enable
to set the fuel consumption unit (l/100
km, km/l or mpg).
If the distance unit set is “mi” (see pre-
vious paragraph) fuel consumption will
be displayed “mpg”.
In this case the option “Cons.Unit” of the
“Setup Menu” can be selected but it is
locked on “mpg”.
To set the required unit proceed as fol-
lows:
❒briefly press button MENU: “km/l”
or “l/100 km” (according to previ-
ous setting) will show on the display;
❒press button +or–to select the re-
quired language;
❒briefly press button MENUto go
back to the menu screen or press the
button for long to go back to the stan-
dard screen.Temperature
This function enables to set the tem-
perature unit (°C or °F).
To set the required unit proceed as fol-
lows:
❒briefly press button MENU: °C or °F
(according to previous setting) will
show on the display;
❒press button +or–to select the re-
quired language;
❒briefly press button MENUto go
back to the menu screen or press the
button for long to go back to the stan-
dard screen. Units
With this function it is possible to set the
units for distance covered (km or mi),
fuel consumption (l/100 km, km/l or
mpg) and temperature (°C or °F).

Values displayed
Average consumption
Represents the indicative average of con-
sumptions from the beginning of the
new mission.
Current consumption
This value shows instant fuel consump-
tion (this value is updated second by
second). If parking the car with engine
on, the display will show “- - - -”.
Average speed
This value shows the car average speed
as a function of the overall time elapsed
since the start of the new mission.
Travel time
This value shows the time elapsed since
the start of the new mission (driving
time).
Range
This value shows the distance in km (or
mi) that the car can still cover before
needing fuel, assuming that driving con-
ditions are kept unvaried.The display will show “- - - -“ in the fol-
lowing cases:
❒value lower than 50 km (30mi);
❒car left parked with engine running
for long.
IMPORTANTThe variation of the au-
tonomy value can be influenced by dif-
ferent factors: driving style (see what is
described in paragraph “Driving style”
in the chapter “Correct use of the car”),
type of route (highways, urban, moun-
tain, etc…), use conditions of the car
(load transported, tire pressure, etc…).
What was described previously must be
taken in consideration when planning
a trip.
Travel Distance
This value shows the distance covered
from the start of the new mission.
Each time the battery is connected and
each time a new mission is started (re-
set), the display will show “0.0”. The “Trip A” displays the figures relating
to:
❒Average consumption
❒Current consumption
❒Average speed
❒Travel time
❒Range
❒Travel Distance
“Trip B” displays information concern-
ing:
❒Travel Distance B
❒Average consumption B
❒Average speed B
❒Travel time B.

CORRECT USE

Gear selection
As soon as the conditions of the traffic
and road allow, use a higher gear. Us-
ing a low gear to obtain brilliant perfor-
mance increases consumption. In the
same way improper use of a high gear
increases consumption, emissions an en-
gine wear.
Top speed
Fuel consumption considerably increas-
es with speed. Avoid superfluous brak-
ing and accelerating, which cost in terms
of both fuel and emissions.
Acceleration
Accelerating violently increasing the revs
will greatly affect consumption and emis-
sions: acceleration should be gradual and
should not exceed the maximum torque.CONDITIONS OF USE
Cold starting
Short journeys and frequent cold starts
do not allow the engine to reach opti-
mum operating temperature. This results
in a significant increase in consumption
levels (from +15 to +30% on the urban
cycle) and emission of harmful sub-
stances.
Traffic and road conditions
Rather high consumption levels are tied
to situations with heavy traffic, for ex-
ample in queues with frequent use of
the lower gears or in cities with many
traffic lights. Also winding mountain
roads and rough road surfaces adverse-
ly affect consumption.
Traffic hold-ups
During prolonged hold-ups (e.g.: level
crossings) the engine should be
switched off.
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 im-
mediately, slowly, avoiding high speeds.
This way the engine will warm faster.
Unnecessary actions
Avoid accelerating when waiting at traf-
fic lights or before switching off the en-
gine. This and also double declutching
is absolutely pointless on modern cars
and also increase consumption and pol-
lution.

–extra-urban cycle: frequent ac-
celerating in all gears, simulating ex-
traurban use of the car; the speed varies
between 0 and 120 km/h;
–combined consumption: is cal-
culated weighing about 37% of urban
cycle consumption and about 63% of
extraurban consumption.IMPORTANT The type of route,
traffic situations, weather condi-
tions, driving style, general con-
ditions of the car, trim level/
equipment/accessories, load, cli-
mate control system, roof rack,
other situations that affect air
drag may lead to different fuel
consumption levels than those
measured.FUEL CONSUMPTION
The fuel consumption figures given in
the table below are determined on the
basis of the homologation tests set
down by specific European Directives.
The procedures below are followed for
measuring consumption:
–urban cycle: cold starting followed
by driving that simulates urban use of
the car;
