1. Manual steering column
Pass the cardan joint of the lower shaft
through the cowl panel whole.
2. Power steering column
Pass the cardan joint of the l ower shaft as
well as the protection bellows through the cowl
panel whole, having previously bound with a
piece of cord, both the cardan joint end and
the bellows eyes.
Cut the piece of cord, position the bellows
on the cowl panel. In both situatio ns, continue with:
In the engine compartment:
Position the cardan joint end of the steering
column lower shaft on the steering box gear
shaft. Fix in th e p o si tion marked when
dismounting, the connection screw between the
s teering column lower shaft and the steering
box gear shaft, without tightening to the required
moment.
In the passengers compartment :
Fix and tighten to the required moment the
six screws attaching the steering column to the
driving post. Return in the engine compart ment for
tight e ni ng t o t he re qui r e d m om e nt , t he
connection screw between the steering column
lower shaft and the steering box gear shaft. For the other parts, remounting is done by
performing the dismounting operations in the
reverse order. Take c are when mounting the i nstrument
panel , t o correct l y connect t he electri cal
connectors.
Characteristics of the steering column
mounting.
The straig ht in line driving position is ensured
by unique positioning of the steering wheel on
the column shaft. Replace the steeri ng wheel attachment
screw after each dismountin g.
Observe the required tightening moment for
the steering wheel attachment screw ( 4.4
daNm).

DISMOUNTING
IMP ORTANT !
Before dismounting the airbag, block
the UCE airbag by means of the CLIP
tester (see chapter 88 “ UCE ai rbag
blocking”). T he airbag indicato r from
the instrument panel is on. Disconnect the battery.
Dismount the two attachment screws of the

DISMOUNTIN G
Dismount :
-s teering attachment screw ( 1) on the
steering column, by means of a screwdriver pro-
vided with TORX T50 head;
- steering wheel (2) not before bringing the
steering to the middle point (wheels are in a di-
rect line); - half-cases (3) and (4) connected be-
tween them by three screws (5) to the steering
column.
In order to dismount the under steering wheel
control from the upper shaft of the steering
w heel, loosen the screw (6) and extract the
under steering wheel control (7).

- rotating contact.
AT T E N T I ON !
It is forbidden the handling of the pyro-
technic system near heating sources or open
fire, because there is the risk of undesirable
s tarting of the system.
IMP ORTANT !
Anytime when dismounting the steering
wheel, it is necessary to dismount the airbag
connector (1). The airbag is provided wi th
a connector who is short-circuited aft er dis-
connecting the wiring connector, avoiding
in this way all undesirable starting.
AT T E N T I ON !
It is forbidden the change of the rota-
tion c ontact position after di smounting
the under-steering wheel control assem-
bly, because there is the risk of i ts dam-
aging.
The under steering wheel control it is pro-
vided with a pre -cut self-a dhe sive tape
stacked on the rotating contact and on the
under steering wheel control body that is not
allowing the undesirable rotation of the rotat-
ing contact until its mounting on the attach-
ment cone of the steering column. In case the position of the rotating contact
is changed, then this one, is to be rotated
clockwise 2.5 complete rotations (or until it
gets blocked), then is to be rotated a nti-
clockwise 2.5 complete rotations.

REMOU NT I NG
Perform the dismounting operations in the reverse order, taking into consideration the follow-
ing recommendations:
-ensure that steering is at middle point (wheels are in a direct line);
- mounting of the lower part dashboard is to be performed by guiding it on a centering part
placed on the driving post cross beam; -steering wheel must freely enter in grooves;
- check the operation of the dashboard instruments and switches.
AT T E N T I O N :
After each steering wheel dismounting, its attachment screw is to be replaced, ob-
s erving the required tightening moment of 4.4 daNm.

Airbag
I mportant!
Before reconnecting the driver’s airbag connector, it is necessary to apply a checking
procedure of the system:
- Check if ai rbag indicator from the instrument panel is on, when the contact is set
on.
- Connect the igniter to the airbag connector (to the wiring) and check if the airbag
indicator is off. - Set the contact off, connect the airbag connector instead of the inert igniter and
attach the airbag on the steering wheel (requiret tightening moment is 0.65 daNm). After remounting, perform the system checking by means of the CLIP tester.
If everything is correct, unblock the UCE airbag (see chapter 88 “Unblocking UCE
airbag”). If is not correct, see chapter “Diagnostic”.
- Check if t he airbag i ndicator from the instrument panel is on for 3 seconds from
setting the cont act on, t hen it is off and i s remaini ng off.
AT T E N T I ON!
No n-observing of prevision prescriptions may cause un abnormal operation of the
sy stem, leading to the airbag undesirable starting.
