The crossmember supporting the steering has slots at its fixing point on the front subframe.
Any vertical movement of this crossmember alters the steering geometry.
WARNING
This operation is only to
be carried out in certain ccxses such as
-accidental impact, with repercussions on the steering system.
-work on the vehicle entoiling removal of steering crossmember.
- vehicle with poor
road stability ( p oar stright-line stability) 01 with excessive tyre weor.
CHECKING

As a precaution. a steering wheel iocking
tool may also be
used. 2. Mark position of vehicle in relation to
ground :
Secure a weighted length of string to the front
bumper. and
mark the position of the weiqht on
the ground ( The
object of this is to always bring
the vehicle

it is possible to use the free projector.
Secure projector to scuttle panel crossmemher, and
focus it onto a fixed object, which will indicate the
initial positioning of the vehicle.

Note front height again.
c) Take the average of these two measurements
which should be between
157 and 173 mm inclusive
At rear :
Proceed in the same manner.
Average of height readings should be between

CHARACTERISTICS AND SPECIAL FEATURES OF THE AIR-CONDITIONING SYSTEM
The air-conditioning system includes the refrigeration and the heating of the air drawn into the passenger compart-

This allows the air in the passenger compartment to be cooled, while at the same time reducing its dampness (and
therefore the misting up of the glass ) HEATING

Remove screws (2) securing bonnet hinge to the
body.
Position suitable shims at u a )) to ensure the
recess of bonnet in relation to front wings : R = 2 mm max.
Fit and tighten screws (2 ). 2. Transversal and longitudinal adjustment :
Loosen hinge fixing screws ( 1 ) on bonnet
Adjust them in order to obtain a clearance
between bonnet and wings : J=6
+ 2.5
-1 mm
- with (I maximum difference of 2.5 mm between
left and right-hand sides and a maximum diffe-
rence in level of 2 mm,
- adjust also to obtain clearance between front
edge of wings and bonnet : E = 0 it3 mm
3. Adjusting the striking plate :
Loosen screws ( 3 )
Centre striking plate in relation to lock.
Tiqhten screws ( 3 ). 4. Adjusting the safety catch :
Loosen screw5 (4 1.
Adjust safety catch so that :
With bonnet resting on catch, the latter must engage
under weight of bonnet alone.

Remove scravs (6 ) and (7 ) and protective
plate (5).
Loosen screws (8) and adjust height of lock
in order to ensure, recess R, at the front.
Tension lock control cable by screwing nut (9 )
to eliminate any clearance on bonnet opening
leV%. Bonnet should lock correctly when dropped
from (I height of 250 mm.
