Maintenance Minder 6 Scheduled Maintenance
Recommended service for your 2006 Honda Ridgeline:

Replace VTM-4 rear differential fluid: Driving in mountainous areas at very low vehicle speeds or trailer towing results in higher level of mechanical (shear) stress to fluid or frequently fully loaded. This requires differential fluid changes more frequently than recommended by the Maintenance Minder. If you regularly drive your vehicle under these conditions, have the differential fluid changed at 7,500 miles (12,000 km), then every 15,000 miles (24,000 km).

Check with dealer most keys now days are programmed to the car you may need to have the new key programmed to your car.

Yes. Replace both sides at the same time.
Some Ridgeline owners have a parts list of after-market items and have seemingly created a stronger version of the OEM part.
look on the ridgeline owners club forum for more info.

To replace the filter on your Honda CBR - Locate your air filter, usually found on top of the engine. On cars with carburetors it is in a round piece of metal about the size of a medium pizza; fuel-injected cars have square or rectangular air filter housings that may be off to the side of the engine. Unscrew or unclamp the top to the air filter housing. Lift out the air filter. It should be a round or rectangular filter made of paper or plastic, with a rubber rim.lightdeal

A means oil and filter change
1 means tire rotation and
2 means replace engine air filter and cabin air filter
hope this helps

Pull out the rubber boots, and unhook the limit slider on the right side.
