The maintenance schedule for the Honda Ridgeline can vary year to year, so I'll toss You some numbers for the 2018, which is representative. You'll want to change the oil (if using conventional) every 10,000 miles and also rotate the tires then. At 30,000 miles, You should replace the cabin air filter, as well as the engine air filter and change the rear differential fluid. At 45,000, You're going to want to flush and replace the brake fluid. When You hit 60k, it's time to change the automatic transmission fluid, the transfer case fluid, and also replace the timing belt. When You reach 90,000 miles, it's time to replace the spark plugs, and at 120,000 miles driven, You'll do a flush and replace for the engine coolant.

The oil should be changed in the honda ridgeline at 7,500 miles. At 15,000 miles, it needs a tire rotation and the rear differential fluid changed. Around 45,000 miles you should have the brake fluid flushed and the transmission and transfer case fluids changed. Coolant needs to be flushed and replaced at 60,000 miles.
