I think you will find that your vehicle, like mine, has run flat tyres. These allow driving when flat at up to 50mph for approx 50 miles. Therefore no spare tyre, jack etc. provided as technically not required as expectation that should the unfortunate puncture occur you are able to drive to a tyre outlet for repair/replacement. Should you not be able to drive the car then recovery is required.
Also Lexus vehicles with cvt should not be towed but placed on a low loader.
