The method to reset the maintenance light on an old Buick GL8 is as follows: 1. Press the "MENU" button, which is located on the light control lever. 2. Select the "Vehicle Information Menu," then turn the adjustment knob to choose "Oil Life." 3. Hold down the reset button at the top of the lever for a few seconds, and the oil life will reset to 100%, completing the reset. Once the maintenance light comes on, it indicates that the vehicle requires maintenance. Automotive technology better protects vehicle components. However, some essential maintenance tasks still need to be performed. Under difficult usage conditions, such as driving in extremely cold or high-dust areas, specific maintenance should be carried out even between scheduled intervals.
