Lights failure
The warning light stays on for about
15 seconds, after the check, when a fail-
ure is detected on one of the following
lights:
– low beam headlights
– high beam headlights
– flashing (only gas discharge headlights)
– side/taillights
– direction indicators
– brake lights (stop lights)
– third stop light
– rear fog guards
– number plate lights.
The warning of a fault may mean one
or more blown bulb, a burnt fuse or cut
off connection.
Turning the key to MARthe warning
light turns on, but it should go out after
about 5 seconds.The turning on of only
the
>warning light with
the engine running normally indi-
cates a fault to the ABS system
only. In this case the braking sys-
tem is still efficient, though with-
out the aid of the anti-lock device.
Under these conditions perfor-
mance of the EBD system may be
reduced. in this case too, you are
advised to go immediately to the
nearest Authorized Alfa Romeo
workshop, driving in such a way
as to avoid sharp braking, to have
the system checked over.

headlamps)
On cars fitted with gas discharge head-
lamps (xenon bulbs)(optional for ver-

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.

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.
