Can tether straps be used in a mini-van?

I have registered for the Alpha Omega seat that is good up to 70lbs & I also registered for the Century Smart Move convertable car seat. I did this b/c they both come with the tether strap included. We just bought a new Toyota Sienna mini van & I don't see what the tether strap will be attached to. A lady on an airplane flight told me she had another mini van & was not able to use her tether straps either. Are tether straps only for sedans or can they be used in vans also?

You can contact your vehicle dealership for information on their locations and on installation.
