Steps to reset the tire pressure warning on the Mercedes-Benz GLC: First, ensure the key is turned to the second position. Use the left directional keys on the steering wheel to navigate to the maintenance interface on the dashboard, then select the tire pressure option to proceed with the settings. The Mercedes-Benz GLC is the first crossover model launched by Mercedes-Benz, with dimensions of 4683mm in length, 1780mm in width, and 1664mm in height, and a wheelbase of 2873mm. When the rear seats of the Mercedes-Benz GLC are fully folded down, the transition is smooth, featuring an expansive body proportion. It offers five driving mode options and provides more spacious seating and storage space compared to the previous generation model.
Last time I encountered a tire pressure warning, I handled it directly: First, I checked if all four tires were around 2.5 bar—measuring when the car is cold gives the most accurate reading. Then, without pressing the brake, I pressed the start button twice to power on the car. Using the small square button on the left side of the steering wheel, I navigated to the 'Maintenance' menu. I found the 'Tire Pressure Monitoring' option, pressed confirm to select recalibration, and the dashboard started flashing a prompt. After driving for about ten minutes, the system automatically recorded the new data. Once, after getting a tire repaired, I forgot to reset it and only remembered on the highway, but the system relearned on its own and the warning disappeared. However, if the warning keeps popping up frequently, it's best to check for a nail puncture or a faulty sensor.
Resetting the tire pressure alarm essentially boils down to three key steps: adjusting the tire pressure, menu operation, and driving confirmation. Make sure all tires are in good condition before resetting, or it'll be a wasted effort. The location of the center console menu in the new GLC is slightly different from the older models—it's recommended to simply say 'Hey Mercedes' to activate the voice assistant and command 'Reset tire pressure.' During my last maintenance visit, I noticed that models with a manual reset button in the spare tire well of the trunk require special attention: after resetting, you must drive for at least 20 minutes to allow the system to self-check. For those who frequently drive on rough roads, it's wise to keep a portable air pump in the car—if the tire pressure is abnormal, inflate first before resetting. If the alarm reactivates the day after resetting, it's likely a slow leak that needs immediate attention.
