How Do I Reset the Tire Pressure Light in a Lexus?
Resetting a Lexus TPMS should be simple maintenance, while repair requires more intensive procedures.

The Tire Pressure Monitoring System (TPMS) is a valuable tool for Lexus drivers to make sure their tires are pressurized enough not only for optimal performance, but to maximize fuel economy and safety. If your Lexus was built after 2007, it was built with TPMS sensors in each tire sending tire inflation information to a receiver. This receiver then warns the driver if one or more tires is underinflated. Underinflation can occur through a small leak or larger puncture, or through the natural loss of pressure that happens as temperatures drop with the change of seasons.
Most of the time, reinflating cold tires to their recommended PSI and driving off is enough to shut off the TPMS warning light. Sometimes, however, it can stay on, confusing the driver and causing them to waste time checking tires that are already at pressure. There are a couple methods by which Lexus owners can reset their TPMS light, but a few reasons a stubborn light may require professional assistance.
The Classic Method to Reset your TPMS Light
The easiest way to reset your Lexus’ TPMS is the same as with many manufacturers: Once the tires are pressurized, drive for about 25 miles or around 50 mph for 10 minutes and it should reset the next time you turn on the car.
Using the TPMS Reset Button
In earlier Lexus models with TPMS, there is a dedicated reset button usually located under the steering wheel, but consult the owner’s manual if you have a hard time finding it. Turn the vehicle’s ignition to “on” without starting the engine; hold the TPMS reset button until the light flashes three times and release the button. Start the car and give it about 20 minutes—the warning light should disappear.
TPMS Reset via Multi-Information Display
In newer Lexus models like the GX, the TPMS reset is accessed through the multi-information display in the instrument cluster. Unlike the reset button method, you’ll need to turn the engine on, then use the arrow keys on the steering wheel to scroll through the vehicle settings until you find the “TPMS” screen. Press and hold the button with a small circle in the center until the TPMS warning light blinks three times. Let the engine run for a few minutes or go for a short drive and the light should disappear.
A TPMS warning light that blinks for approximately a minute before staying on can indicate a malfunction in either the system or a sensor. It’s best to bring your Lexus to a dealer or specialist, as most issues related to a TPMS sensor will necessitate the whole system being reinitialized. This includes one or more sensors being replaced, or might be something as simple as having the tires rotated.
