Mercedes-Benz GLA maintenance tips: The Mercedes-Benz GLA comes with a whole vehicle warranty of two years or 60,000 kilometers, with the engine and transmission warranty lasting five years or 100,000 kilometers.

I've been driving a Mercedes for several years and am quite familiar with resetting the service light. First, turn off the engine without pressing the brake pedal, then press the start button twice to power up the instrument cluster. The multifunction buttons on the left side of the steering wheel come into play here—use the left and right buttons to navigate to the trip menu, then scroll up and down to find the ASSYST PLUS option. Once in the menu, select the complete service confirmation reset, and the system will recalculate the service interval. After completion, turn off the power, wait ten seconds, and restart the car—the yellow wrench symbol will disappear. Here’s a tip: it’s best to reset it immediately after servicing to ensure accurate reminders next time. If your instrument menu is in English, don’t worry—the Mercedes me App has Chinese reference images. Doing it yourself is more convenient than visiting the dealership, but older models may require diagnostic computer intervention for resetting.
Last time I reset the maintenance light for my wife's GLA, I found the procedure for the 2022 model was slightly different. After powering on, press the home button on the left side of the steering wheel, swipe left three times to enter the settings menu, and you'll directly see the yellow wrench icon. Click into it, select ASSYST PLUS to confirm the reset, and don't forget to check the oil change option. The whole process takes about two to three minutes, but pay special attention: hybrid versions need to be in READY mode to operate, while regular fuel versions just need to be powered on. After resetting, drive three kilometers for the system to update the data—avoid repeatedly checking during this period. If the menu doesn't respond, it might be due to low battery voltage; it's recommended to start the engine and try again. Nowadays, dealerships don’t proactively reset after maintenance, so learning this trick can save you time.
