SECURING THE LOAD
The loads carried may be blocked with
straps hooked to the special rings in the
boot corners (fig. 140). The rings also
serve to secure the luggage retaining net
(available on request c/o Alfa Romeo Au-
thorized Services).
fig. 140
678PGSm
Do not load the luggage
compartment above the
permitted maximum (see “Techni-
cal specifications”). Also make sure
that the objects contained in the
boot are well secured to prevent
them from being thrown forward
causing harm to the passengers in
the event of sharp braking.
WARNING
A heavy load that has not
been secured may cause
serious harm to passengers in the
event of an accident.
WARNINGIMPORTANT Travelling at night with
a load in the boot it is necessary to adjust
the height of the low beam headlights
(see next paragraph “Headlights” in this
chapter). For correct use of the aiming
device, also make sure that the load does
not exceed the values given in the same
paragraph.

111
GAS DISCHARGE HEADLIGHTS
(optional for versions/markets where
applicable)
Gas discharge headlights (xenon) work
with a voltaic arc, in an atmosphere satu-
rated with pressurised xenon gas, instead
of the incandescent filament.
The lighting produced is remarkably
higher than that of the conventional light
in both terms of the quality of the light
(lighter) and of the amplitude and posi-
tion of the lit area.
The advantages offered by better light-
ing are noted (due to less sight fatigue
and better orientation capability of the
driver, thus of travelling safety) especially
in bad weather, fog and/or insufficient
signs, because of the higher lighting
of the side beams which are normally
shaded.
The heavy increase of lighting in the
side beams considerably increases driving
safety because it allows the driver to bet-
ter see other users at the sides of the
road (pedestrians, cyclists and motorcy-
clists).Very high voltage is needed to trigger
the voltaic arc, after which the supply can
be at low voltage.
The headlights reach their maximum in-
tensity after about 15 seconds from
switching on.
The high luminosity produced by this
type of headlight calls for the use of an
automatic system to keep the headlight
beam aiming constant and prevent daz-
zling other vehicles when braking, accel-
erating and carrying loads.
The electromechanical system for auto-
matic constant beam aiming makes the
headlight aiming device superfluous.
Xenon lights are very long-lasting and
failure is unlikely.
If necessary, have the
system checked and any
repairs done only by Authorized Al-
fa Romeo Services.
WARNING

112
AIMING LOW BEAM
HEADLAMPS FOR
LEFT/RIGHT CIRCULATION
(only for versions with gas discharge
headlamps)
On cars fitted with gas discharge head-
lamps (xenon bulbs)(optional for ver-
sions/markets where applicable) with
high lighting power, when passing from a
country with right circulation to one with
left circulation or vice versa it is necessary
to change the aiming of the low beams,
to optimise lighting of the edge of the
road and avoid glaring vehicles met.
IMPORTANT Contact Alfa Romeo Au-
thorised Services to have low beam head-
lamps correctly adjusted.
BEAM AIMING
(excluding versions with gas discharge
headlights)
The adjustment of the headlights is vital
to your safety and comfort and to that of
other road users.
The adjustment of the headlights is also
governed by precise regulations.
Contact Alfa Romeo Authorized Services
to have the headlights correctly adjusted.
When returning to the
country of origin, re-
member to change the low beam
aiming again.
WARNING
To have the position
checked and if neces-
sary adjusted, contact
Alfa Romeo Authorized Services.
ADJUSTING THE FRONT
FOGLIGHTS
