Question about 2007 Lexus RX 350 FWD

Lexus ls430 2004 tire pressure indicator

The tire pressure light came on indicating low air in tire. Purchased new tires at goodyear, checked pressure. light is still on.

How do I get it turned off? 07 Lexus Rx350....my pressure is right after we had a brief cold spell and the tire air pressures have been checked and double checked. Light remains on. Have done the "reset" procedure in the book several times. Light stays on.

    I didn't buy new tires.........that was someone else post -- don't know how it got attached to mine. Nope, my tires are like new with a hair over 8K on them. Am thinking about putting a little round stickie on the dash so I don't have to see the light. HA!

    where is the reset button for the tire air monitor?
    cold weather affects mine as well. tires have nitrogen (from dealership) in them instead of regular air, don't know how that effects them.

    i'd like to also turn the service light off too and do the oil myself

Veve713:
You probably didn't need new tires unless you had some miles on it. Remember that the spare tire also has a pressure monitor as well. It most likely is causing the low tire pressure light on the dash and only needs to be inflated back to what ever your other tires are set to. I had the same problem on my RX and took it back to the dealership where they told me since the spare is exposed to the same elements (it's under the back of the RX - you have to use the tire iron to let the spare down), it will inevidably lose air.

Good luck.

    anyone with common sense knows your spare will lose air over time...but i hope you not suggesting your light comes on when your spare tire is not even on the car??????? the sensor is on for a reason....try inflating your tires to 37 psi.....on all tires .......40 on your spare........problem solved...if not trade it in..........you havent seen nothing yet.....

That signal is from your tire monitoring sensors, telling you that there is air pressure difference between tires. The tire pressure should be same in all tires.

My 2008 Suzuki SX4 tire pressure indicator light has been on for weeks. I have checked the tire pressure on all tires and everything seems ok. Can anyone tell me why this light is still on?


You will need the dealer to scan the system for the problem that giving you a false indication of low pressure. Also make sure the spare has the correct pressure.

Took 2009 fusion sel for 4 new tires at local goodyear, when returned the front end shakes, take back still shakes, take back third time and the front doesnt shake, but the turn indicators don't work,...


sounds like you had the "new kid" working on your car. its hard to find good help these days. the service adviser should have had his better technicians look at it after the first numb skull laid hands on it. as far as the lighting problems i would say it sounds like a blown fuse or an unplugged light connector. you should have your ford dealer check it out and see if it looks like something has been tampered with. good luck. and try firestone complete autocare next time. usually better managed. usually.

There is a light on the dash that looks like a horseshoe with an exclamation point inside...didn't get a manual....what does this icon mean


I believe this is a low tire pressure indication.
This is supposed to be a tire with an exclamation.
A 5-10 psi drop could set this off.

Either your pressure indicator is bad or the tire gauge you used is bad. Don't go by what the air pumps say, use a decent tire gauge.

The " Check Engine" pertains to the computer sysytem informing you of a failure code stored. In order to clear , the problem must first be solved, and then clear the computer. Tire prssure warning light advises of low air pressure in any of your tires. Check tire pressures. A fault in a particular tire valve sensor may also indicate a fault if all pressure are up to spec

Lexus ls430 2004 tire pressure indicator


Make sure you check the spare tire too; had this problem on another model and the dealer said it was the spare which is also monitored.  Good news in case you need it one day.
