IMPORTANT
To avoid all risk of damage to the systems, apply
the safety and cleanliness instructions and opera-
tion recommendations before carrying out any
repair:
- (see 62A, Air conditioning, Air conditioning:
Precautions for the repair, page 62A-1) ,
- (see Vehicle: Precautions for the repair) (01D,
Mechanical introduction).
Note:
Use blanking plugs for the fuel circuits with part no.
77 01 208 229 or 77 01 476 857 to plug any open-
ings exposed to the open air. They must be clean.
