Honda Ridgeline maintenance schedule
The Honda Ridgeline maintenance schedule runs on the Maintenance Minder, not a printed mileage chart. The truck shows a code such as B1 or A16 when service is due. Two Ridgeline items need extra attention: the V6 has a timing belt (code 4), and the all-wheel-drive rear differential has its own fluid (code 6). Brake fluid is due every 3 years, whatever the display says.

How the Maintenance Minder works on a Ridgeline
The Minder watches engine temperature, load, and trip length, and turns them into an oil-life percentage. At 15% it shows a main code: A for an oil change, B for oil, filter, and a list of inspections. Numbers 1 through 6 are added when other jobs are due at the same visit. If no code appears within 12 months of the last reset, change the oil anyway. Every code explained: Honda Maintenance Minder codes. How Honda’s schedule works across its lineup: Honda maintenance.
Ridgeline service items by generation
The items below come from Honda’s Ridgeline manuals, in our own words. The Minder sets the timing; the extra mileages apply only to the hard-use conditions Honda names.
2nd generation (2017–2026)
Reminder system: Honda Maintenance Minder.2 Oil changes: when the Maintenance Minder shows it, at least once a year.
| Service | When |
|---|---|
| Tire rotation | code 1 (Maintenance Minder)2 |
| Engine air filter and dust and pollen filter | code 2; every 15,000 miles in dusty or sooty conditions2 |
| Transmission and transfer fluid | code 3; every 30,000 miles or 2 years in hard use (2020–2023 manuals)2 |
| Spark plugs, timing belt, water pump check, valve clearance | code 4; timing belt every 60,000 miles in extreme heat, extreme cold, or towing2 |
| Engine coolant | code 5 (Maintenance Minder)2 |
| Rear differential fluid (AWD) | code 6; in hard use at 7,500 miles, then every 15,000 miles2 |
| Brake fluid | every 3 years2 |
1st generation (2008–2014)
Reminder system: Honda Maintenance Minder.3 Oil changes: when the Maintenance Minder shows it, at least once a year.
| Service | When |
|---|---|
| Tire rotation | code 1 (Maintenance Minder)3 |
| Engine air filter and dust and pollen filter | code 2; every 15,000 miles in dusty or sooty conditions3 |
| Transmission and transfer fluid | code 3 (Maintenance Minder)3 |
| Spark plugs, timing belt, water pump check, valve clearance | code 4; timing belt every 60,000 miles in extreme heat, extreme cold, or towing3 |
| Engine coolant | code 5 (Maintenance Minder)3 |
| VTM-4 rear differential fluid | code 6; in hard use at 7,500 miles, then every 15,000 miles3 |
| Brake fluid | every 3 years3 |
The timing belt: code 4
Unlike most Honda four-cylinders, the Ridgeline’s 3.5-liter V6 uses a rubber timing belt in both generations. Code 4 calls for the belt, a water pump inspection, new spark plugs, and a valve clearance check. Under normal use the Minder decides when, and the manual gives no fixed mileage. If you tow a trailer or drive in very high or very low temperatures, Honda says to replace the belt every 60,000 miles in the U.S. Many owners replace the water pump at the same time, since the labor overlaps. More: timing belt replacement.
Rear differential fluid: code 6
Every first-generation Ridgeline has VTM-4 all-wheel drive, and most second-generation trucks have i-VTM4. Both use a rear differential that needs Honda’s own fluid; on the 2017–2023 trucks the manual names Honda DPSF-II. Code 6 brings it up. If you tow, carry heavy loads, or drive in the mountains, Honda wants it changed at 7,500 miles and then every 15,000 miles. Front-wheel-drive trucks from 2017–2020 never show code 6. See differential fluid and B16.
Normal or severe use?
Honda prints no separate severe schedule for the Ridgeline, because the Minder already shortens oil life for towing, idling, and short trips. A few items still follow your conditions, not the display: the timing belt at 60,000 miles for towing or temperature extremes, the differential fluid at 7,500 and then every 15,000 miles in hard use, the transmission fluid every 30,000 miles or 2 years in hard use on 2020–2023 trucks, and the air filter every 15,000 miles on dusty roads. The general idea: normal vs severe maintenance.
Keep the record
The Minder resets after each visit and keeps no history. A dated list of codes, mileage, and receipts shows which schedule your truck followed, which matters most for the timing belt when you sell. Related: brake fluid flush, Ridgeline oil, and car maintenance log.
FAQ
Does the Honda Ridgeline have a timing belt?
Yes. Both generations use a timing belt on the 3.5-liter V6. The Minder schedules it with code 4, and Honda says to replace it every 60,000 miles if you tow or drive in extreme heat or cold.
How often does a Ridgeline need differential fluid?
When the Minder shows code 6. In hard use, such as towing, Honda wants it at 7,500 miles and then every 15,000 miles.
What does B16 mean on a Ridgeline?
Oil and filter with inspections (B), tire rotation (1), and rear differential fluid (6).
How often should Ridgeline brake fluid be changed?
Every 3 years. On the Ridgeline this is a calendar item, not a Minder code.
