Methods to reset the persistent tire pressure warning light on a Lexus: 1. Locate the button next to the enter key near the central air vent, press it a few times until the dashboard displays the tire pressure reset option, then hold down the enter key; 2. Check if the dashboard shows the total mileage display (if not, press the return button on the lower left side of the steering wheel to show the total mileage); 3. Press the upward arrow button on the left side of the steering wheel (the dashboard will display English text), then press the R button on the dashboard (if there isn't one, press the protruding lever on the dashboard once); 4. Press and hold the button at the lower left corner of the dashboard until the display shows the vehicle's maintenance items, navigate to the tire pressure setting using the button on the lower left side of the steering wheel, and then press the adjacent BC button to reset. Taking the Lexus ES as an example, its body dimensions are 4975mm in length, 1866mm in width, and 1447mm in height.
I've been driving a Lexus for years, and the tire pressure light staying on is indeed a hassle. A few days ago, my car had the same issue, which gave me quite a scare. First, don't panic—the most basic step is to check the pressure of each tire by pressing them manually or using a pressure gauge to see if they're within the recommended range, usually around 32-35 psi. If the pressure is normal, it might be a sensor issue, such as a dead battery or poor wiring contact. Try resetting the system while driving: before starting the car, locate the menu button on the steering wheel, navigate to the settings menu, and select the tire pressure option to reset. If the light remains on after resetting, it could mean one of the sensors is faulty and needs replacement, or you may need a comprehensive diagnosis at a 4S shop. Remember to check tire pressure regularly, especially during seasonal changes between winter and summer, as this can prevent many potential hazards. Safety comes first—never ignore it to avoid the risk of a high-speed blowout.
As a car enthusiast, I think there are several common reasons why the tire pressure light won't turn off: insufficient tire pressure is the prime suspect, which can be fixed by adding air; secondly, false alarms caused by sensor malfunctions. Lexus systems are quite sensitive, sometimes the light stays on for a few minutes after starting the car before turning off normally. If it stays on continuously, a manual reset is needed. The method is simple: sit in the car without starting the engine, hold the settings button for a few seconds to enter the menu, find the tire pressure reset option, and confirm. If it still doesn't work, you might need to check if the sensors on the wheels are damaged. These things have a lifespan of about 5-7 years, and if the battery dies, they need to be replaced. The cost isn't high, but professional tools are required. I recommend buying a home tire pressure gauge to check the tire pressure monthly. Early detection and treatment can extend tire life and save fuel.
