OEM Bike Rack Question

[RosscoPCole]

We have recently bought a new to us T6.1 and had the dealership fitted an OEM bike rack. We have noticed that the two longer attaching arms are a lot looser than the shorter two. When the tailgate opens they fall and touch the rear window. If I forget and not put them back they stop the rear wiper.
Is this normal? Is there a way of tightening them so it doesn't happen?
Thanks

Screw them down as if you were fastening a bike on.

Screw them down as if you were fastening a bike on.

This is what I do as well (took me 2 weeks to work it out though!). Turn the clamp part that normally attaches to the bike frame around through 180 and clamp the jaws down on to the Wheel supporting channels when rack is in stored upright position.

The longer the arm and s the more moment acting on the clamp.

As others have said, do this.

No need to undo them when unfolding rack, they release automatically.
