The easiest way is to clarify on the website of Thule. Here you can find the suitable carrier system on the vehicle data. As a rule, there are several support systems that fit, and you have here already follow a little to his taste.
If the carrier system is mounted, which is lightning fast at Thule, also the roof bike rack is mounted in a few moments, if you've done it before. For the Assembly does not require any help. The hardest part is the lifting of the wheel on the roof bike rack. But the wheel is in the receiving points, the rest is just a formality. The wheel itself is first using a swiveling "tong", which is attached to the bicycle frame, detained. This "tong" is then closed with a simple rotating mechanism so that they firmly clutching the frame. Then the wheels with ratchet straps ("tooth bands") are tightened. Finally, the bike carrier should be completed so that the "tong" is firmly attached.
It is the way suggested to equal even Thule One-Key-System (8 cylinder because not enough 4) to procure. So then you have the advantage that footpacks (and support system) and roof bike rack can be secured with a key on the roof. Otherwise, you are already very busy with looking after each correct key. The One-Key-System can be retrofitted at any time also.
Meanwhile, a summer later, I get my bike within 10 minutes on the roof, without anything was installed previously. So I do not go to the support system through the area, because the course unnecessarily cost fuel.
