A tow prep kit is displayed in the "other" drop-down menu under the car features list in this advertisement (I read it here https://nerdycar.com/toyota-highlander/). A bigger alternator, radiator, and gearbox oil cooler are added. The vehicle is "prepared" by these items to tow large weights. I'm not sure if this truck has a receiver hitch installed, but once one is, it will have the "guts" to perform some hefty lifting.
