Finally I found the 'switch' button under the glove box. But no matter it's pushed in or out, the low tire pressure light is still on :(

No, they just added more air and changed the engine oil, nothing else. I wish I didn't press the 'reset' button but I did that by following this thread :) Also, I called my local Lexus dealer and told them the whole story. They asked me to inflate all 5 tires to 34 psi and I did, but the light is still on. I will check the 'switch' button under the glove box tonight to see if that can fix the problem or not. Thanks a lot for the input! All the best, Tom

Guys, I need your help! The low tire pressure light on my 2007 RX 350 was on during highway driving yesterday. I checked the tires right after that and found one of the aluminum tire valve caps was missing. All other 3 caps were very lose as well. I did the oil change the day before yesterday and I saw them added more air into the tires, so I believe they didn't tighten the valve caps :( My question is - could the low tire pressure light be triggered by the missing valve cap? BTW, I checked the tire pressure of all 5 tires including the spare tire and all of them were above 30 psi. Also, I followed this thread and deflated all the tires including the spare. Did the reset and did the proper inflation of the tires to >30 psi. But the light is still on. When I turn on the engine, the light is just flashing for about 60 times and then keeps on. Could this be the problem with sensors? Should I take the car to the dealer now? Any input is welcome, thanks a lot! All the best, Tom
