ated sliding wing preventing direct sun rays.
To open the wing pull handle (A-fig.
131).
When opening the sunroof, the wing is au-
tomatically pushed inside the roof panel.
When closing the sunroof, the wing comes
out partially in order to have access to the
handle for manual closing.
EMERGENCY OPERATION

provided in the tool bag rotate bushing
(C-fig. 133) of the motor to move the
sunroof.
IMPORTANT When the operation has
been ended the key should be turned half
a turn in the opposite direction until a
click is heard before it is removed.LUGGAGE

The boot lid can be opened from outside
the vehicle and from inside the vehicle.
IMPORTANT If the boot is not prop-
erly shut, the corresponding warning light
on the check panel will come on.
OPENING FROM OUTSIDE
(fig. 135)
Turn the badge (A) in the direction
shown by the arrow, insert the key (B)
and turn it anticlockwise.
Opening is facilitated by a servocontrol
which operates the lock.

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.
