How Toyota schedules service: Maintenance Required Light
Toyota's owner's manual splits service into Schedule 1 (severe) and Schedule 2 (normal). Most US drivers fall under Schedule 1 because it covers short trips, extreme temperatures, dusty roads, or heavy idling. The intervals below reflect Schedule 1 — the schedule Toyota recommends for typical real-world use.

Owners of specific models were notified that remedy parts were available starting January 21, 2021. Owners of other models will be notified as remedy parts become available. Remedy parts should be available for all affected vehicles by late March 2021. Owners may contact Toyota customer service at 1-888-270-9371 or Lexus customer service at 1-800-255-3987.

AIR BAGS:FRONTAL
Campaign #20V734000 · 25/11/2020
Issue: Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2020-2021 Toyota Avalon and 2020 Avalon Hybrid, RAV4, and RAV4 Hybrid vehicles. Breakaway pins within the steering column, designed to absorb energy and reduce injury during a crash, could have been damaged during production, possibly affecting the performance of the driver's air bag in the event of a crash. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 208, "Occupant Crash Protection."
Risk: In the event of a crash, an air bag that does not perform as designed can increase the risk of injury.
Fix: Toyota will notify owners, and dealers will replace the steering column, free of charge. The recall began December 18, 2020. Owners may contact Toyota customer service at 1-800-331-4331. Toyota's number for this recall is 20TB17/20TA17.

A short circuit may develop in the Occupant Classification System (OCS) sensor, preventing the front passenger air bag from deploying.
Risk: An air bag that does not deploy during a crash increases the risk of injury.
Fix: Dealers will inspect and replace the sensor as necessary, free of charge. Interim letters notifying owners of the safety risk were mailed in February 2024. Some final remedy owner letters were mailed October 31, 2024. Letters will continue to be mailed in phases through January 2026. Owners may contact Toyota customer service at 1-800-331-4331. Toyota's number for this recall is 23TB15/23TA15 Lexus 23LB03/23LA03.
Essential maintenance
Critical for safety and preventing major damage
Engine Oil & Filter
Every 5,000 miReplace 0W-20 full-synthetic oil and filter every 5,000 miles under Schedule 1, or 10,000 miles under Schedule 2. Toyota covers the first 2 oil changes through ToyotaCare.
Estimated cost — typical U.S. ranges
Dealer
~$120–$160
Shop
~$85–$115
DIY
~$25–$55
Full synthetic costs more than conventional. 5-quart 0W-20 + filter is the typical bill.
Tire Rotation
Every 5,000 miRotate tires every 5,000 miles. Toyota recommends rotation at every oil change to maximize tire life on FWD and AWD models.
Estimated cost — typical U.S. ranges
Dealer
~$85
Shop
~$60
DIY
Free
Often free at the shop where you bought the tires — worth asking before paying.
Brake Inspection
Every 5,000 miInspect brake pads, rotors, and parking brake every 5,000 miles. Toyota recommends measuring pad thickness at each service.
Estimated cost — typical U.S. ranges
Dealer
~$85
Shop
~$60
DIY
Free
Most shops do this free as a courtesy with any service. Don't pay separately if you can avoid it.
Brake Fluid
Every 30,000 miReplace DOT 3 brake fluid every 30,000 miles or 36 months. Critical for the integrity of the ABS, VSC, and brake assist systems.
Estimated cost — typical U.S. ranges
Dealer
~$180–$200
Shop
~$125–$140
DIY
~$10–$25
DOT 3 or 4 — match the cap. Vacuum bleeders make this a one-person DIY.
Important maintenance
Keeps your vehicle running smoothly and efficiently
Engine Air Filter
Every 30,000 miReplace the engine air filter every 30,000 miles. Earlier under Schedule 1 if driven on unpaved roads.
Estimated cost — typical U.S. ranges
Dealer
~$60–$95
Shop
~$45–$70
DIY
~$15–$40
5-minute job on most cars; the airbox lid usually has clips, no tools needed.
Automatic Transmission Fluid
Every 60,000 miToyota labels ATF as 'lifetime fill' on most automatics, but recommends inspection and replacement every 60,000 miles under severe service. Use Toyota WS or Type-IV — no substitutes.
Estimated cost — typical U.S. ranges
Dealer
~$330–$500
Shop
~$235–$355
DIY
~$60–$180
Some sealed transmissions have no dipstick — fill is precise and best left to a shop. Many drivers can still DIY drain-and-fill.
Spark Plugs
Every 120,000 miToyota iridium-tipped spark plugs are rated for 120,000 miles. Earlier replacement reduces fuel economy and can cause misfires on direct-injection engines.
Estimated cost — typical U.S. ranges
Dealer
~$285–$390
Shop
~$200–$275
DIY
~$25–$100
Iridium plugs cost more but last 100k+ miles. V6/V8 access varies wildly — some are tough.
Super Long Life Coolant (SLLC)
Every 50,000 miToyota SLLC (pink): first change at 100,000 miles, then every 50,000 miles. Do not substitute green or orange coolant — it will damage the cooling system seals.
Estimated cost — typical U.S. ranges
Dealer
~$285–$330
Shop
~$200–$235
DIY
~$25–$60
Use the manufacturer-specified coolant — wrong color/chemistry can damage the cooling system.
Recommended maintenance
Extends the life of your vehicle and improves comfort
Cabin Air Filter
Every 30,000 miReplace the cabin air filter every 30,000 miles, sooner in dusty climates. Located behind the glove box on most Toyota and Lexus models.
Estimated cost — typical U.S. ranges
Dealer
~$60–$95
Shop
~$45–$70
DIY
~$15–$40
Usually behind the glovebox. Shops charge labor for a 10-minute job — easy DIY win.
Serpentine / Drive Belt Inspection
Every 60,000 miInspect the serpentine belt and tensioner every 60,000 miles. Toyota uses long-life EPDM belts that rarely fail before 100,000 miles.
Estimated cost — typical U.S. ranges
Dealer
~$195–$235
Shop
~$135–$165
DIY
~$20–$50
DIY-friendly if you can reach the tensioner. Inspect for cracks rather than swap on a strict mileage interval.
Timing Chain — No Replacement
On condition / lifetimeToyota's 2AR-FE, 2GR-FKS, A25A-FKS, and most Toyota engines built since 2010 use a timing chain rated for the life of the engine. No scheduled replacement.
Estimated cost — typical U.S. ranges
Dealer
~$85
Shop
~$60
DIY
Pro only
Timing chains are normally lifetime. Listen for rattle on cold start — that's the actionable signal. Replacement is major work, quote separately.
