Reset the maintenance light on a vehicle after routine maintenance, such as oil and filter changes, have been completed. The maintenance light, which may also appear as illuminated text reading “Maint Req’d,” appears lit up or blinking when the car reaches a certain mileage milestone.
In some vehicles, the maintenance light turns on 5,000 miles after the last time the maintenance light was reset. This does not take into account that the vehicle may have been serviced with routine maintenance at some point during the 5,000 miles of operation since the maintenance light was last reset. Reset a maintenance light manually.
