I've been driving my GLK300 for several years, and resetting the maintenance light is quite simple. I did it myself after the last service. First, you need to park the car securely without starting the engine, just turn the key to the second position, or press the start button without stepping on the brake. Then, hold down the round OK button on the left side of the steering wheel for a few seconds until the dashboard lights up with the menu. Use the small paddle on the right to scroll up and down, find the submenu labeled something like 'Service,' enter it, and select the maintenance reset confirmation. The key is not to panic during the crucial steps—the whole process takes about a minute. Remember to reset it promptly after each service; otherwise, the light stays on, which can be annoying and affect your driving mood. Some older models might have slightly different menu names, but the method is generally similar. Extra tip: Make sure the doors are closed during the operation to avoid distractions. Safety first—never attempt this while driving.
Having worked in the auto repair industry for a long time, resetting the Mercedes maintenance light is part of my daily routine. For the GLK300, the common method is to turn the ignition switch to ON without starting the engine, then locate the ASSYST button or a similar button on the lower right side of the steering wheel, hold it for three seconds to enter the menu. Switch the screen to the maintenance option, use the directional keys to select the reset option and confirm, and the light will go off. Tip: Make sure all maintenance tasks are completed before performing this operation, otherwise you're just fooling yourself and it's unsafe. Sometimes it may fail due to low battery voltage, so it's recommended to check the battery level first. Most car owners can do this themselves, saving the hassle and cost of going to the dealership. Although the process is simple, it requires careful step-by-step execution—don't rush. Common issues include the menu getting stuck, in which case try a few more times, or refer to the owner's manual for more precise instructions. Overall, it's quick and easy to master.
