51 31 ... Notes on gluing windshield and rear window (Protection): Hardening:

The glue hardens through reaction with air moisture at room temperature.

The minimum hardening period is achieved at 22°C and 38% relative air humidity:

• refer to table.

The car must not be subjected to load on one side during the minimum hardening period, for example:

• one wheel on the curb.
• lifting platform.
• etc.

Moving around inside the workshop on a flat surface is permitted but do not under any circumstances drive over approach ramps for example in multi-storey car parks.

If the minimum hardening times are not adhered to:

• the window glass will be displaced, causing leakage and wind noises.

Minimum hardening times:

• refer to table (without passenger airbag).
