Maintenance minder on Honda use calculations based on mileage, oil temperature, and RPMs to calculate the service your Ridgeline should have.
You need to replace the engine oil and the oil filter, rotate the tires, inspect the front and rear brakes, and check the parking brake adjustment and lights all round, rotate the tires and Replace the transmission fluid and transfer
fluid if equipped.
