How to reset the tire pressure on the new Mercedes-Benz E300L?

The tire pressure monitoring indicator is a yellow symbol, an irregular circle with no seal on top, four small spikes at the bottom, and an exclamation mark inside. The illumination of the tire pressure monitoring indicator indicates abnormal tire pressure. Abnormal tire pressure is generally caused by the following three reasons: Abnormal tire pressure: Typically, an alarm is triggered if the pressure is below 1.8 bar or above 3.0 bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset in time, the system will still record the previous data, causing the tire pressure monitoring indicator to illuminate. In this case, simply perform a tire pressure reset. Damaged tire pressure sensor: The tire pressure sensor is used to monitor tire pressure and is directly installed inside the tire, connected to the tire inflation valve. If the sensor is damaged due to impact while driving, it can also trigger the tire pressure warning light. For sensor damage, the only solution is to replace it with a new component.
I’ve been driving a Mercedes-Benz E300L for a while and am quite familiar with the tire pressure reset procedure: First, don’t start the ignition—just turn the key to the ACC position to power up the dashboard. Then, look at the central control screen, tap the 'Vehicle' icon to enter the menu, scroll to the 'Services' option, select 'Tire Pressure Monitoring,' and confirm by clicking 'Reset.' After resetting, remember to drive for about 15-20 minutes to let the system auto-calibrate the positions. I usually check the tire pressure monthly, keeping it around 2.5 bar for better fuel efficiency and to prevent blowouts. If the reset fails the first time, it’s likely due to a sensor issue or low pressure—get it checked promptly to avoid risks.

Resetting before long trips ensures safer, more reliable drives with fewer 'mood swings' from your car.
