I brought my RX350 to the dealer for this problem before. They told me to inflate my tires to 36psi for winter time although the recommended pressure is 30 psi

    Its a sad day when an entire generation doesn't know how to change a spare tire. Take a course on auto maintenance, use synthetic motor oil and practice changing your spare tire in the driveway. There will come a day when you are on a desolate road, no cell phone signal and you have a flat tire.
    BTW, check the spare tire. All your tires should be at 36PSI. Auto Mfgr want lower tire pressure for smooth ride. Tire mfgr want higher tire pressure for longer wear.
    Good luck and stop calling AAA for everything.

Absolutely check the spare... especially when the temp has dropped few degrees from the usual norm.... Also 40 psi is too high to be driving around long term, based on tire wear and ride quality.
The RX350 spare tire lowers on a cable to ground ... cranked down from inside the trunk area..... the owners manual shows it pretty well

I recently had the Lexus dealer address the low tire light (11,000 miles under warranty?). They checked the air pressures and advised that the TPMS needed to register sensors $115.00. I read the warranty and they never excluded this work.

There are two switches associated with the tire pressure light on the RX350. The second switch is on the passenger side and selects an alternate pressure setting for an alternate set of tires such a snow tires. The second switch should be in the "Out" position. It is located in a very bad location and can easily be bumped by the passenger to the "In" position which will select the alternate tire setting. Set the switch to the "Out" position, then set your tire pressures to about 28 PSI (and don't forget about the spare which also has a sensor). Turn the key to the on position. (Some claim that the emergency brake must also be set, but I do not believe this to be true.) Then depress the reset switch on the driver side and hold until the light illuminates three times - then release. Leave the key in the ON position for an additional 5 - 15 minutes to allow the new pressures to be recorded and the system reset. Turn off the key, (release the emergency brake if set) and then start the engine and the light should be reset. I then recommend re-inflating the tires to the recommended 30 - 32 PSI pressure.

2008 Lexus ES 350 low tire pressure warning light


1) go to a gas station with an air pump. Unless u have an inflator/compressor at home with the tireattachment

2) lower all 5 air pressures including the spare in the trunk to maybe about 28 PSI

3) now reset the TPMS (on the 07 there is a button to "calibrate" the TPMS and it is located under the dash. I presume it is the same on the 08.)

4) now bring the pressue back up to 30/32 or whatever it says on the door area


If this doesn't work, it is possible u have a defective TPMS
but my bet right now would be that someone "calibrated" the TPMS to the current tire pressure so the light is constantly on. It happened to me before when my daughter was messing around and hit that button.

I changed 1 of my valve sensor so i need to no how to reset the tpms light


By operating the tire pressure warning reset switch, the tire pressure warning ECU can be set to issue a warning at an inflation pressure that corresponds to the standard pressure of tires .Therefore, you must set the warning threshold to the proper value in order to comply with the local regulations .Operate the tire pressure warning reset switch only after the inflation pressures of all tires have been adjusted on the vehicle.To initialize the system, press and hold the tire pres- sure warning reset switch for 3 seconds or longer with the ignition switch in the ON position. When the system receives the
initialization signal, the warning light blinks 3 times (1 second on, 1 second off). During initialization, the tire pressure warning valve and transmitter measures the inflation pres sure of the tire, and registers the signals that are transmitted into the tire pressure warning ECU at a frequency of once per minute. The initialization process is completed when signals from all the tires have been received. It takes a few minutes .

At what tire pressure is the tire pressure warning indicator activated


The LOW TIRE PRESSURE warning light will come on when the pressure is 25% below the manufacturer's recommended pressure. If I recall correctly, the 2007 Sonata has a manufacturer's recommended tire pressure of 30 psi. There is a tire label (sticker) on the inside driver's door jamb ('B' Pillar which tells you what the manufacturer's recommend tire inflation pressure should be. Once you have that value, you can calculate 25% of that & find the pressure at which the warning light should come on. NOTE: The TPMS (Tire Pressure Monitoring System) does not continually nor constantly scan the sensors in the wheels for this information - once every 3 to 10 minutes.

Are all tires at correct pressure? Some of the cars also use one in the spare tire. if the spare has a tire valve like the other 4 tires it has a sensor.

Lexus ls430 2004 tire pressure indicator


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.

Dashboard light


For Lexus the ! symbol usually is low tire pressure that's all there's sensors in each wheel that report to the car that the pressure is low, also if your wondering how much air to put in the tires you can look by opening up the driver or sometimes the passenger side door and look along the door there's a label that will tell you each tires recommended pressure. Any other questions just ask and id be glad to help you folks, and if you don't mind if you can rate my answer if you get a chance it would be greatly appreciated..
