Check the front part of the assembly: direct
a water jet towards the headlamp glass.
Is the water penetrating inside the headlamp?
Is wa ter penetrating inside the parking-turning
lamp?
Visually check the headlamp rear part; rubber
protecto r of the headlamp bulb is correctly
mounted?
The he adlamp adju stment corrector is well
mounted?
The headla mp bulb is correctly mounted?
The aera tion holes are clogged?
The hea dl amp is steamed out or it has
condensa tion water inside?
Visually check the rear part of the parking-
turning lamp; t he parking bulb holder is
correc tly mounted?
Th e turning bulb holder is correctly mounted?
Replace the headlamp.
Replace the parking-turning lamp.
Mount corr ectly the rubber protector of the
h eadlamp bu lb. If this is not good, replace it.
Mount corr ectly the headlamp adjustment
co rrector and its rubber protector. If protector
is not good, replace it.
Mount correc tly the headlamp bulb.
If possible, eliminate the clogging cause. If
no t possible, replace the headlamp.
Explain th e client that this fact is a natural
one, no t a damage and there is no headlamp
corro sion risk. The condensation water will
disappear when the headlamp will be lighted;
the disappearing time of the condensation
wat er is subject to the environmental
humidity .
Mount co rrectly the parking bulb holder. If
its gasket is not good, replace it.
Mount co rrectly the turning bulb holder. If
its gasket is not good, replace it.
REMARK : If the client is i nsisting, proceed to headlamp drying:
- blow with dry air, if possible;
- naturally dry the headlamp by turning on the headlamps for couple of minutes

MEETING LIGHTS ADJUSTMENT (LOW BEAM)This is performed by acting upon the V screw
(vertically plane adjustment) or H (horizontally
p lane adjustment). By screwing, the lighting beam
is ”lowering” and by unscrewing is “ascending”. Check if the l ighted area is centered on the
vertical axis and if the optical separation at 15°
coincide with the headlamp lighting. An error of
1 cm is admissible. A lighting beam displaced towards left has
the aspect shown in (p icture a) and a lighting
beam displaced towards right has the aspect
shown in (picture b )
ROAD LIGHTS ADJUSTMENT (LONG BEAM)
Check the position to c oincide with the
adjustment pe rformed for low beam and with
the lighting beam distributed between the two
vertical lines on the panel
When checking the long beam, the lighting
center of t he ellipse, must be l ocated on t he
cross marking the screen center. If a m ajor de viation c ompared with t he low be am i s noticed, i t is re commended t he bul b
replacement, this one being in most of the cases, responsible for such defect.

FOG P ROJECTORS ADJUSTMENT
The fog projectors adjustment is to be performed in the following conditions:
- the vehicle to be placed on a horizontal surface;
- the vehicle has not passengers inside the cockpit or weights in the trunk;
- the tires a re pressurized a t the manufacturer prescribed pressure.
Further on, proceed as follows:
Bring the vehicle at the working place.
Position the adjustment device (headlamp adjustment device –E) in front of an optical center
of a fog lamp. Switch on the fog projectors. Rotate the adjustment screw of the fog lamp (D), by means of
a scre wdriver ( A), so that a n adjustment of 2 % i s obtained and t he separation between t he
lighted area and the dark one from the adjustment device is l ocated under the marked line (G)
This adjustment is to be performed in the same way as for the meeting lights adjustment.
Bring the adjustment device in front of the optical center of the second fog lamp;
Perform the fog projector adjustment;
Switch off the fog projectors.

Disconnect the (-) plug of the battery;
Dismount
the headlamp adjusting control from the turning lamp-headlamp assembly:
- pull backward the gasket of the headlamp adjustment corrector ( 1);
- detach from clips the protector (2) of the headlamp adjustment mechanism;
- loosen the locking nut ( 3);
- detach from clips the he adlamp adjustment control cable ( 4) from the headlamp
adjustment corrector and then from the fork (5);
Dismount the headlamp adjusting control from the other turning lamp-headlamp assembly .
Detach from clips the headlamp adjustment control cables and cut the attachment collars.
Dismount the headlamps adjustment control button.
Dismount the attachment nut of the headlamp adjustment control on the dashboard.
Dismount the bonnet opening control cable from the opening handle (see chapter 52).
Detach from clips, by means of a straight screwdriver, the cables passing bushing from the
cowl panel.
Remove the headlamps adjusting control cables from the cowl-passin g hole. Mark the mounting
position of the headlamps adjustment control cables.
REMOU NT I NG
Insert the headlamps adjusting control cables through the cowl-passing hole, observing the

Replacement of the headlamps mechanic adjustment control
Attach on the cowl panel, by means of clips, the cables passing bushing, ensuring the cockpit
co mpartment sealing against possible water drain along the cables passing bushing.
Mount the bonnet opening control cable in the opening handle (see chapter 52). Position the
headlamp s adjustment control on the dashboard.
Mount the attachment nut of the headlamps adjustment control on the dashboard.
Mo unt the headlamps adjustment control button and turn it in the position “3”.
Mount the headlamp adjustment control to a turning lamp-headlamp assembly :
-a ttach in clips by means of a straight screwdriver, the headlamp adjustment control cable
in fork (5) a n d t h en in the headlamp adjustment corrector;
- tighten initially the cable by hand till the fork ( 5) is in contact with support ( 6) so that fork
is remaining at max. 0.5 mm again st the support;
-block the headlamp adjustment cable by means of the nut ( 3);
-a ttach in clips the protector ( 2) o f t h e headlamp adjustment mechanism;
- position correctly the gasket of the headlamp adjustment corrector – the vertical adjustment
screw ( V) mu st come out through the gasket.
Mount the headlamp adjustment control of the other turning lamp-headlamp assembly.
Attach in the attachment points, by means of clips, the headlamps adjusting control cables,
replace and mount the attachment collars, observing the mounting position prior to the dismounting.
Keep a distance of approximate 40 mm
± 10 mm between the right cable and the cylinder
no .1 spark plug cable, in order to avoid the loses due to electric-magnetic induction.
Reconnect the battery ( -) term inal.
Switch on the headlamps and check the operation of the headlamps mechanic adjusting control.
The adju stment of the luminous spot dip of the headlamps in the downward sense of the vehicle
loading condition is to be performed by bringing the headlamps adjusting button in the “ 0” position
an d then in the desired condition.
REMA RK : The r equired tighteni ng moment of the attachment nut of th e headlamps
adju stment control on the dashboard: 2 Nm.
