I’ve been driving my GLK300 for over five years, and I always reset the maintenance reminder myself. After parking the car, turn the key to the second position—make sure not to start the engine, just let the dashboard lights come on. Then, use the buttons on the left side of the steering wheel to scroll up and down through the menu until you find the ‘Maintenance’ or ‘Service’ option, select it, and press OK to reset. If the wrench symbol disappears, it means you’ve succeeded. If the reset fails, it might be because the engine isn’t off or the battery voltage is unstable—in that case, remove the key and wait a few minutes before trying again. The key point is that after resetting, the system will recalculate the next maintenance interval, which is really handy. Remember to perform regular maintenance to keep the car in good condition and extend its lifespan. I check the tires and engine oil once a month and take a quick look at the warning lights to avoid unnecessary trips to the dealership and extra costs. The whole process takes just two minutes, and once you get used to it, it’s super convenient.

When I first started, I was a bit intimidated by the GLK300's maintenance light, but after checking the manual, I found it wasn't hard to operate. First, insert the key and turn it to the ACC position. Once the dashboard displays, use the arrow keys on the steering wheel to browse the menu, find the maintenance option, and confirm the reset. Don’t panic if it doesn’t work the first time—it might just be a delay in the vehicle’s system. Be patient and try again. The reset light is just a reminder that maintenance is due, but don’t forget to actually change the oil and filter, as this directly affects engine health. Doing it yourself can save on service fees—I recorded the steps on my phone for easy reference. For beginners, I recommend starting with simple tasks like regular car body cleaning to build confidence before tackling similar issues.

The reset system of the Mercedes-Benz GLK300 is designed based on CAN bus. Turn the key to ignition position two, use the steering wheel controls to enter the instrument menu, select the Assyst Plus item, and then perform the reset. The key point is that the vehicle must be stationary and the engine must not be started, otherwise the menu may not pop up. If the reset fails, check the fuse or battery status, and use a diagnostic tool to read the fault codes if necessary. This method avoids unnecessary external intervention, and the operation can be completed in just one minute by yourself.
