Wheel change at Laguna III year 11/09

Hello together, I bought a second-hand Laguna III in May this year. I also got winter tyres from my Ranault dealer. I didn’t have a spare wheel in my car, but only this tyre filling set. Now I wanted to change the tyres and could not find any places under my car where I can start the shunting car lifter. Can someone give me a tip. Photos might not be bad either. Thank you in advance!
