SPECIAL NOTES FOR VEHICLES FITTED WITH A
DRIVER’S AIRBAG
IMPORTANT
To avoid any risks of destroying the rotary switch
under the steering wheel, comply with the
following instructions:
• Before removing the steering column and the
rack, the steering wheel MUST be immobilised
with the wheels straight using a "steering
wheel locking" tool, throughout the whole
operation.
• Any doubts about whether the steering wheel
is centred means that the steering wheel will
have to be removed so that the centring
method described in section 88 "Airbag" can
be applied.
REMINDER: in this case, only qualified, trained
staff can carry out this operation.
Remove:
- the expansion bottle (secure it to the engine),
- the upper right hand mounting bracket of the
radiator and unclip it (left hand side), then
keep it to one side by securing it to the
engine.
98753R
Disconnect:
- the heating hoses on the engine,
98711R1
