What is the meaning of over drive off light?

The "overdrive off" light indicates that the vehicle's overdrive feature is deactivated. Overdrive is a gear that allows the engine to run at lower RPMs while maintaining speed, improving fuel efficiency. When the light is illuminated, it typically means the transmission is operating in a lower gear, which can provide more power for acceleration or climbing hills but may reduce fuel efficiency. Drivers can usually toggle this feature on or off using a button or switch in the vehicle.
