Start the engine and enter the odometer interface on the dashboard. Press and hold the OK button on the left control area of the steering wheel while simultaneously pressing the phone button on the right side of the steering wheel. A menu will then appear. Select ASSYST-PLUS and press the OK button to enter, then choose the full maintenance option and press OK again. Select 'Confirm Full Maintenance' and press the confirmation button once more. Below is more information about the maintenance light: 1. Once the maintenance light comes on, it indicates that the vehicle requires servicing. Some models can only reset the maintenance light using the brand-specific diagnostic tool, and manual reset is not possible. Automotive technology has improved the protection of vehicle components, but certain regular maintenance tasks must still be performed to reduce future repair costs. If you frequently drive in harsh road conditions, vehicle maintenance should be performed ahead of schedule, even if the scheduled maintenance time has not yet arrived. 2. The purpose of the maintenance light is to record the mileage of important components, similar to a timer in a sprint race, serving as a reminder for both the vehicle owner and maintenance personnel. If the owner replaces relevant parts but does not reset the maintenance light, it will not affect the vehicle's performance. However, it may cause inconvenience for future part replacements, as the exact usage time of the new components cannot be accurately tracked.
