Nope those are two different things, the AVS which is standard on the GS 460 and GS 450h is (Active Variable Suspension) This is different from ASSS (Active Stabilizer Suspension System) One dampens your suspension the other controls the sway bar and suspension. You would know you have a ASSS if your trunk has no spare tire.
