How to reset the tire pressure light on a Mercedes-Benz R300?

After the tire pressure indicator light comes on, first check the tire pressure monitoring function for abnormal wheels on the car's navigation screen. If an alarm occurs due to excessive tire pressure, you can slightly increase the tire pressure to the safe value. If the display shows low tire pressure, you need to reset it and then drive the car for a while.
Recently, I helped a friend reset the tire pressure warning light on a Mercedes-Benz R300, and it's actually quite simple. First, start the engine but keep the vehicle stationary. Then, look for the button area on the left side of the steering wheel, use the up and down arrows to scroll to the 'Service' or 'Settings' option in the instrument cluster menu, and find the 'Tire Pressure Monitoring' submenu. After entering, you'll see a 'Reset' button—just press the confirm key to select it, and you're done. Remember, always check that all tire pressures are correct before resetting. Mercedes-Benz typically recommends a tire pressure between 2.3 and 2.5 bar for both front and rear tires; use a tire pressure gauge to ensure there are no leaks. If you drive without resetting, the light might stay on and be annoying. If the light turns off after resetting, it means everything is normal. If the reset fails, it could be due to an electrical issue or a faulty sensor, so it's best to have the tire pressure system checked at a professional shop.
