Help identifying this warning light please?
I posted about this earlier in the week and finally got a picture. Sorry it's blurry, wife took with her phone.
Thanks
Thanks

Check your manual...tells you what you need to do. Normally says one of the tires is low in air pressure...

Tire Pressure
Its always the spare. Ive had my RX350 for 18 months. Both times the light came on. It was the spare.
The procedure to reset the light is in the owners manual.

The light resets itself fairly quickly AFTER you have filled up the tires with air. You only need to use the electronic reset if the "set point" for the indicator is too high--such as if you decided to switch from filling your tires from 35 psi to 30 psi to get a softer ride.

My '04 RX330 has the early model tire pressure warning lights that inferred low tire pressure by wheel speed rather than by actual pressure measurement used on later models. Here, a low tire will have a smaller diameter and will turn slightly faster than the others. A chip constantly compares the signals from the 4 ABS sensors on each brake rotor, and if one wheel is running faster than the others, the warning light is illuminated.
This comparative system has alerted me to a couple of slow leaks that could have been dangerous. It's surprisingly sensitive. It's pretty foolproof, and it's cheap - using the ABS sensors to perform double-duty. (Yes, if ALL FOUR tires were low, the system wouldn't respond, since it is making a comparison, not a real measurement - however that's unlikely.) The only disadvantage to this system is that it tells you A tire is low, but not WHICH one. You have to walk around and look, or check with a gauge.
Inflating all tires to the proper pressure and driving a block or so should switch off the lamp. If you need to reset the chip , there is a button on the bottom edge the dash next to the steering column that will tell the chip that THIS is the new "normal". This is handy when replacing tires. If you don't know which button to push (on FWD models there is an identical button alongside that switches the VSC off), look at the warning lights again and if the "VSC off" is illuminated, you pushed the wrong one. Try the other one.
