NOTE: Using the "Roll Out 2000" system (sourcing reference: BMW Workshop Equipment and Planning Documentation) minimizes paintwork and ergonomic damage as well as damage that is hazardous to health.

WARNING: Follow safety instructions for working on cars with airbag systems (risk of injury). (See 51 00 ... SAFETY INSTRUCTIONS FOR WORKING ON CARS WITH AIRBAG SYSTEMS )

IMPORTANT:

Take care when handling sharp-edged tools and cutting wire (risk of damage to head airbag).

IMPORTANT:

Always keep both suckers dry and clean to ensure their optimum adhesion on the windscreen. Lubricate coil if interlock rattling becomes too loud.

Always wear protective goggles and gloves for your own safety.

Preparatory work:

To avoid paintwork damage, tape off working area over large area at outlet of wire starter (2) with fabric adhesive tape (1)
Cut off required length (A) from cutting wire (A) = Window diagonal x 4
Check whether wire can get caught on rivets or retainers; if necessary, insert guide needles in bonding joint and guide cutting wire past
