Tire pressure warning

[aprild714]

Is there an actual tire pressure warning that will pop up on the dash while you are driving to warn you of low pressure in a tire? I came out of the store and my tire was dead flat. No warning that I was losing air. Took the tire to be fix and they said it was ruined because I drove on it flat! How would I drive on a flat tire and not notice!

Yes, the system would put a warning on your instrument cluster for low tire pressure. Here are images from the OM. The systems typically trigger at a 10% air pressure loss. To check if yours is working let air out to 25PSI and see if there is a warning.

Also, does your vehicle status page or your Lexus app show pressures for all tires + the spare?

Thanks for the reply. I’m going to Lexus today to get the tire fixed. I’m going to have them show me where this warning light is because if it’s stuffed in the corner with all those other lights, how is someone supposed to see it while they’re driving down the road? My truck would flash a giant warning in front of my face when my tire pressure was low. Another reason I’m not really loving this car.

Unfortunately I can confirm there is a light on the cluster as well as a warning that pops up on the cluster (though the pop up didn't seem to stay up for long). Had a recent occurrence on-trail where the warning popped up. The tire held until we made it back to camp and plugged it, but later gave up and had to be changed.

The pressures can all be seen in the main screen (including the spare) and the app (spare not visible) from my experience.
