Values displayed
Average consumption
This value shows the average consumption
from the start of the new mission.
Actual consumption
This value shows instant fuel consumption
(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 need-
ing fuel, assuming that driving conditions
are kept unvaried.
The display will show “- - - -“ in the fol-
lowing cases:
❒value lower than 50 km (or 30 mi);
❒car left parked with engine running for
over 5 minutes.
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 (reset),
the display will show “0.0”.
IMPORTANTLacking information, TRIP
COMPUTER values are displayed with “- - - -”.
When normal operating condition is reset, cal-
culation of different units will restart regular-
ly. Values displayed before the failure will not
be reset. The GENERAL TRIP displays the figures re-
lating to:
❒Average consumption
❒Actual consumption
❒Average speed
❒Travel time
❒Range
❒Travel Distance
TRIP B displays information concerning:
❒Average consumption B
❒Average speed B

CORRECT USE OF THE CAR
172
Never leave children un-
attended in the car. Al-
ways remove the ignition
key when leaving the car and take
it with you.To avoid useless con-
sumption of power and
possible draining of the
battery, never leave the ignition
key in the MAR position when the
engine is not running.
PARKING
When the car is parked, proceed as fol-
lows:
– Switch off the engine.
– Engage the handbrake.
– Engage first gear if the car is faced up-
hill or reverse if the car is facing downhill.
– Turn the front wheels so that the car will
immediately come to a halt if the handbrake
slips.
REDUCING
RUNNING COSTS
AND ENVIRONMENT
POLLUTION
By following a few simple guidelines, it
is possible to save car running costs and re-
duce harmful emissions.
GENERAL CONSIDERATIONS
Car maintenance
To take care of the car maintenance have
the checks and adjustments carried out in
accordance with the “Scheduled Mainte-
nance Programme”.
Tyres
Check the pressure of the tyres routinely
at an interval of no more than 4 weeks: if
the pressure is too low consumption levels
increase as resistance to rolling is higher.
Useless loads
Never travel with an overload in the boot.
The weight of the car (especially in urban
traffic), and its geometry heavily affect con-
sumption levels and stability.Electric services
Use electric devices only for the amount of
time needed. Rearscreen heating, addition-
al headlights, windscreen wipers and heater
fan need a considerable amount of energy,
therefore increasing the requirement of cur-
rent increases fuel consumption (up to
+25% in the urban cycle).
Climate control system
The climate control system is a further load
bearing heavily on the engine inducing high-
er consumption levels(up to +20% on av-
erage). Outside temperature permitting,
preferably use the air vents.
Aerodynamic items
The use of non-certified aerodynamic items
may adversely affect air drag and con-
sumption levels.

CORRECT USE OF THE CAR
173
CONDITIONS OF USE
Cold starting
Short journeys and frequent cold starts do
not allow the engine to reach optimum op-
erating temperature. This results in a sig-
nificant increase in consumption levels (from
+15 to +30% on the urban cycle) and emis-
sion of harmful substances.
Traffic situations and road
conditions
Rather high consumption levels are tied to
situations with heavy traffic, for example
in queues with frequent use of the lower
gears or in cities with many traffic lights. Al-
so winding mounting roads and rough road
surfaces adversely affect consumption.
Stopping in the traffic
During prolonged stops (e.g. level cross-
ings) it is advisable to switch the engine 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 consump-
tion and emissions. It is therefore advisable
to move off immediately, slowly, avoiding
high speeds. This way the engine will warm
faster.
Pointless manoeuvres
Avoid accelerating when waiting at traffic
lights or before switching off the engine. This
and also double declutching is absolutely
pointless on modern cars and also increase
consumption and pollution.
Gearshifting
As soon as the conditions of the traffic and
road allow, use a higher gear.
Using a low gear to obtain brilliant per-
formance increases consumption.
In the same way improper use of a high
gear increases consumption, emissions and
engine wear.Top speed
Fuel consumption considerably increases
with speed. Maintain an even as possible
speed, avoiding superfluous braking and ac-
celerating, which cost in terms of both fuel
and emissions.
Acceleration
Accelerating heavily taking the engine to
a high speed has a considerably adverse ef-
fect on consumption and emission levels;
it is wise to accelerate gradually and not ex-
ceed the maximum torque.

CAR MAINTENANCE

DIESEL FUEL FILTER
(diesel versions)
DRAINING CONDENSATION
WATER
The presence of water in
the supply circuit may
cause serious damage to
the entire injection system and
cause irregular running of the en-
gine. If the warning message +
symbol are shown on the recon-
figurable multifunction display con-
tact Alfa Romeo Authorized Ser-
vices as soon as possible to have
the system relieved. If warning in-
dications turn on after refuelling,
water has probably been poured
into the tank: turn the engine off
immediately and contact Alfa
Romeo Authorized Services.
AIR CLEANER
The air cleaner is connected to the tem-
perature and air flow sensors which send
to the control unit the electric signals need-
ed for correct operation of the injection and
ignition system.
It must therefore always be in perfect con-
ditions, to ensure correct operation of the
engine, low consumption and exhaust emis-
sion levels.
If the operations concern-
ing cleaner replacement de-
scribed below are not car-
ried out correctly and with the due
precautions, they may compromise
the travelling safety of the car. You
are recommended to have this op-
eration carried out by Alfa Romeo
Authorised Services.
If the car is habitually
used in dusty areas, the
cleaner should be replaced
at shorter intervals than those
specified in the Programmed Main-
tenance Schedule.
Any attempt to clean the
cleaner may damage it,
leading to serious engine
damage.

TECHNICAL SPECIFICATIONS

FUEL CONSUMPTION
The fuel consumption figures given in the
table below are determined on the basis of
the homologation tests set down by specif-
ic European directives.
The procedures below are followed for
measuring consumption:
–urban cycle: cold starting followed by
driving that simulates urban use of the car;–extra-urban cycle: frequent accel-
erating in all gears, simulating extraurban
use of the car; the speed varies between 0
and 120 km/h;
–combined consumption: is calcu-
lated weighing about 37% of urban cycle
consumption and about 63% of extraurban
consumption.

the vehicle, trim level/equip-
ment/accessories, load, presence of
a roof rack, use of the climate con-
trol system, other situations that af-

el consumption levels than those
measured (see “Reducing running
