"dont listen tto anyone in hear (sic) but me!!!!!! GO and call your local state or highway patrol for advice."
Unfortunately, the police are not likely to be technical experts regarding the AWD system on a Toyota Highlander. While it is a good idea to consult with the police regarding statutes that might mandate the use of tire chains in certain conditions, the Owner's Manual is still the best source of information regarding that specific vehicle's compatibility with tire chains.
If the chains do not have sufficient clearance with any one of a number of suspension, driveline, or steering components on a Highlander, or if the driveline is just not designed for the use of tire chains, the result could be...very expensive...and no warranty is going to cover owner-inflicted damage like that.
As I said previously, "A well-meaning forum member could give incorrect information that could cause damage to your vehicle. The Owner's Manual should be your trusted source for information regarding the safe and economical operation of the vehicle."
