smart maintenance light reset method is: 1. Turn on the ignition switch, press the button on the left side of the instrument panel three times consecutively; 2. Press the confirmation button on the left side of the steering wheel, the instrument will display a maintenance service prompt, then use the plus/minus buttons on the right side of the steering wheel to select "Reset All Services"; 3. Press the confirmation button, the instrument will display "Reset Successful", then turn off the ignition switch to exit. The smart is a microcar from German automaker Mercedes-Benz, with body dimensions of 2695mm in length, 1663mm in width, and 1555mm in height, and a wheelbase of 1873mm. The smart is equipped with front MacPherson and rear torsion beam non-independent suspension, and the brake combination consists of front disc and rear drum brakes.
Resetting the smart maintenance light is simple and practical, and I often do it myself. Make sure the car is parked with the handbrake engaged and the key is turned to the ON position without starting the engine. Then, look at the dashboard, find a button such as the trip reset button, and hold it for about 5 seconds until the light goes off. If that doesn't work, try pressing the setup menu button to enter the maintenance options and confirm the reset. After completing the operation, start the car to check if it was successful. Remember, the maintenance light is there to remind you of regular maintenance, so don't just reset it and ignore the actual maintenance needs. Regularly resetting it can also prevent false alarms. For beginners, it's best to check the owner's manual or ask a repair shop to confirm model differences.
Resetting the maintenance light requires a bit of technique, which I've handled multiple times. First, turn the key to the ACC position to power up the dashboard without starting the car. Locate the reset button combination near the steering wheel, such as holding the Trip or ODO button for about 10 seconds to observe the light turning off. For newer smart models, you may need to access the vehicle settings in the central control screen to reset it. If the light turns off after the operation, it's successful; otherwise, try again. Remember, this is just a counter—real maintenance issues still require professional inspection to avoid compromising vehicle safety, which is crucial.
As a smart car owner, I recommend the DIY method for resetting the maintenance light. Sit in the driver's seat, turn the key to the ON position without starting the engine, locate the instrument panel button such as 'Settings' or 'Reset', and hold it down for a few seconds until the light should disappear. The operation is simple but ensure accuracy to avoid any mishandling.
