The wrench is the most common tool, so it is also used as an indicator light icon. When you see the yellow wrench indicator light on the vehicle, it reminds the user that the vehicle is due for maintenance.
Generally, the vehicle computer program automatically calculates when the next maintenance time is based on the specified mileage or usage time. Once the mileage or time reaches the set value, the yellow wrench will light up.
The car owner only needs to take the vehicle for maintenance, and the service provider will remove the yellow wrench icon after completing the maintenance work.
