WARNING
In order to eliminate any risk of damaging the
rotary switch under the steering wheel, observe
the recommendations below:
!Before the steering column and the steering
rack are uncoupled, the steering wheel MUST
be immobilised with the wheels straight for the
duration of the operation using a "steering
wheel locking tool".
!If there is any doubt regarding the correct
alignment of the rotary switch, the steering
wheel must be removed so that the alignment
procedure described in the "AIRBAG" section
can be applied.
REMINDER: in this case, only qualified
personnel who have received training may carry
out the operation.
