Useless loads
Do not overload the boot (especially in
town), as this will heavily affect fuel con-
sumption and stability of the vehicle.
Roof rack/ski rack
Remove the roof rack or ski rack imme-
diately after use. These accessories lower
air drag and adversely affect consumption
levels. For particularly bulky loads the use
of a trailer is preferable.
Electric services
Use electric devices only for the neces-
sary time. Rearscreen heating, additional
headlights, wipers and the heater fan
consume a considerable amount of ener-
gy, increasing the need for current highers
fuel consumption (up to +25% in the ur-
ban cycle).Climate control system
The climate control system is a further
load that weighs considerably on the en-
gine inducing higher consumption levels
(on average up to +20%). Outside tem-
perature permitting, preferably use the air
vents.
Spoilers
The use of spoilers that have not been
certified by Alfa Romeo can adversely af-
fect air drag and fuel consumption.DRIVING STYLE
Starting
Do not warm the engine stationary at i-
dle speed or high speed: in these condi-
tions the engine warms much more slow-
ly, increasing consumption and emissions.
It is therefore advisable to move off im-
mediately and slowly, avoiding high
speeds. This will warm up the engine
more quickly.
Pointless manoeuvres
Avoid revving the engine when waiting
at traffic lights and before switching the
engine off. This, like revving before
changing gear, serves absolutely no pur-
pose on modern cars and increases con-
sumption and emission levels.
Gearshifting
As soon as the road and traffic condi-
tions permit it, engage a higher gear. The
use of a low gear to obtain lively acceler-
ating increases fuel consumption.
In the same way, incorrect use of a gear
increases consumption, emission and en-
gine wear.

Halogen bulbs must be
handled touching only
the metallic part. If the
transparent bulb is touched with
the fingers its lighting intensity
is reduced and the life of the bulb
may be compromised. If touched
accidentally, rub the bulb with a
cloth moistened with methylated
spirits and allow to dry.
Where possible the
bulbs should be re-
placed by Alfa Romeo
Authorized Services. The correct
operation and positioning of the
external lights are vital to the
safety of the vehicle and its pas-
sengers and the subject of specif-
ic laws.
Halogen bulbs contain
pressurised gas, in the
case of breakage they may burst.
WARNING

IF ONE OF THE
INTERNAL LIGHTS
GOES OUT
FRONT ROOF LIGHT
To replace the bulbs (Type B, 10W Halo-
gen):
– Remove the roof light (A-fig. 68)
levering in the point illustrated.
– Remove the screen (B-fig. 69)
firstly releasing it from the catch (C) on
the right and then from the two stoppers
on the left.
– Remove and replace the bulb con-
cerned (D-fig. 70) (tubular with bayo-
net coupling), pushing gently and turning
counter-clockwise.When refitting the roof
light ensure that the
electrical wiring is cor-
rectly arranged and does not in-
terfere with the edges of the
light or retaining clips.
– Refit the screen (B-fig. 69), firstly
inserting the left side under the two stop-
pers then on the right side until the catch
clicks. (C-fig. 69).
– Refit the roof light firstly inserting the
front part, then pressing in the rear part
to fit it in place.

FUSES AND RELAYS IN THE
BOOT
Fuses and relays are housed in the
right-hand side of the boot are housed in
a box, in the recess closed by cover (A-
fig. 92).
To open the cover turn the knob (B).
The devices protected by the fuses in
the boot are listed in the tables on next
pages.IMPORTANTThe arrangement of the
relays may vary depending on the ver-
sions and markets. In the event of a sus-
pected anomaly, contact Alfa Romeo Au-
thorized Services.Circuits operated by relays are the fol-
lowing (fig. 93):
A.Air mixing actuator, climate control
unit, additional heater control (JTD ver-
sions)
B.Rearscreen heating relay
C.Seat warming control, elec-
trochromic driving mirror, sun visor light,

(*) Loads not to be exceeded. It is the owner’s responsibility to place loads in the boot and/or on the loading surface within the maximum permissible weight limits.
(**) With special fittings (sunroof, trailer towing device, etc.) the unloaded weight increases, thereby reducing the useful capacity with regard to maximum permissible
loads.

FUEL CONSUMPTION
The fuel consumption values shown in the following tables were established during homologation tests prescribed in specific European
Directives.
The test conditions adopted include the following:
–an urban cycle:this includes cold starting followed by simulation of a mixed urban route;
–an extraurban cycle:this includes frequent accelerating in all gears, simulating normal extraurban use of the vehicle; the speed
varies between 0 and 120 kph;
–combined consumption:this is calculated by considering a route consisting of about 37% urban cycle and 63% extraurban cy-
cle.
IMPORTANT The type of route, traffic conditions, weather conditions, driving style, conditions of the vehi-
cle, trim level/ equipment/ accessories, vehicle load, presence of a roof rack, other items that negatively
affect the aerodynamics of the vehicle or wind resistance may lead to different fuel consumption levels than
those measured by the above-mentioned procedures (see “Economy and environment-friendly driving” para-
graph in the “Getting the best out of your car” chapter).
