I followed instructions in owners guide to no avail.  I took it to Les Schwab

suggestions?

If tires are inflated to 35psi and do not go below 32psi the light will not come on. So check that the tires are inflated to the correct tire pressure rating on the tires, shops now days only fill to 32 or so psi its up to you to do your own correctly. We take ours to the dealership for service as its under warranty and every single time I leave from there the low tire pressure light comes on first time I went back since I was only a few miles from there and they acted like everything was fine went around a 4 tires checking pressure light did go off but came back on before I got back home so I checked and one tire had 31psi all others had 32psi I looked at the tire it said 35psi so I filled to 35psi, then every trip back over there even after telling them in person to leave my tire pressure at 35psi they take air out and light comes back on by the time I get home and have to fill back to 35psi. If the tires have 32 or more psi the light goes off from what I have researched and observed on my own car so fill them to 35psi and also it saves you some gas cost as under inflated tires will get you less MPG and save tire wear too.

Also note I have a $80 tire pressure gauge and $275 pump/refill station set up I bought to be very accurate because I change ATV tires here at home to save money as everyone young enough to ride in my family does ride. So I know my set up is very accurate, I know exactly the tire pressure.

Your car is old enough that it may be time to replace all the tire pressure sensors. They are powered by batteries that are designed to last 5 to 10 years. See the link below or do a "Google" search for "tire pressure sensor battery life".
