Every visit includes a tire rotation and fluid, brake, wiper and floor mat checks; the engine oil and filter are replaced every 10,000 miles; differential oil, ball joint, brake line, exhaust, steering and propeller shaft boot inspections and a propeller shaft bolt torque are added every 15,000 miles; and the cabin and engine air filters are replaced every 30,000 miles.

From the maintenance charts (5,000 to 150,000 miles) of Toyota's 2026 4Runner and 4Runner i-FORCE MAX Warranty & Maintenance Guides, read November 10, 2026. Each later visit also includes the items of the shorter intervals that fall on it. In Hawaii only, the charts also list adding EFI tank additive at every 5,000-mile visit. The all-fluid-levels check includes looking for leaks from sealed transmissions, transfer cases and differentials, the power steering fluid (if equipped), the brake fluid level and condition, and the engine and inverter (if equipped) coolant level, condition and freezing point.
Miles or months: which comes first
Toyota recommends scheduled maintenance every 5,000 miles or six months, whichever comes first. The guides give two examples: if you drive 5,000 miles in less than six months, get maintenance at 5,000 miles; if at six months you have driven less than 5,000 miles, get maintenance at six months.
For low-mileage drivers, the guides suggest marking your calendar to get maintenance every six months. They also stress checking the engine oil level once a month, and point to the "Maintenance and Care" section of the owner's manual for the ongoing fluid checks and visual inspections between visits. For the oil viscosity rating, they refer to the owner's manual.
The 4Runner i-FORCE MAX guide opens with safety precautions for the high-voltage hybrid system: do not touch or try to remove or replace any high-voltage (orange-colored) wiring and connectors. For the HEV battery cooling intake filter cleaning procedure, it refers to the "Maintenance and Care" section of the owner's manual.
Special operating conditions
The charts add these services only if most of your driving is done under the conditions shown. If you only occasionally drive this way, the guides say the extra services are not necessary.
Dirt or dusty roads
Both guides, every 5,000 miles or 6 months: replace the engine oil and filter; inspect the engine air filter (replace it every 30,000 miles), ball joints and dust covers, drive shaft boots (if applicable), propeller shaft boots (if applicable), and steering linkage and boots; and torque the nuts and bolts on the chassis and body and the propeller shaft bolts. Replace the transfer case oil (if applicable) every 30,000 miles.
Towing, car-top carrier or heavy loading
Both guides: torque the chassis and body nuts and bolts and the propeller shaft bolts and inspect the propeller shaft boots every 5,000 miles; replace the front (if applicable) and rear differential oil every 15,000 miles and the transfer case oil (if applicable) every 30,000 miles; and inspect the automatic transmission fluid at 30,000, 90,000 and 150,000 miles and replace it at 60,000 and 120,000 miles. Not all vehicles are designed for towing; see your owner's manual.
Rough or muddy roads, or melted snow
Inspect the propeller shaft boots (if applicable) every 5,000 miles.
Roads with road salt
Torque the propeller shaft bolts and inspect the propeller shaft boots (if applicable) every 5,000 miles.
Extensive idling or low-speed driving
Extensive idling and/or low-speed driving for a long distance, such as police, taxi or door-to-door delivery use: inspect the automatic transmission fluid at 30,000, 90,000 and 150,000 miles and replace it at 60,000 and 120,000 miles.
Short trips below freezing
Repeated trips of less than five miles in temperatures below freezing (32°F): replace the engine oil and filter every 5,000 miles or 6 months, even when the maintenance reminder does not appear.
From the Special Operating Conditions charts in Toyota's 2026 4Runner and 4Runner i-FORCE MAX Warranty & Maintenance Guides, read November 10, 2026.
Daily checks after off-road driving
On top of the mileage chart, both guides list items to check every day when you take the 4Runner off-road through deep sand, mud or water:
- Ball joints and dust covers
- Brake lines and hoses
- Brake linings/drums and brake pads/discs
- Differential oil
- Drive shaft boots
- Engine air filter
- Nuts and bolts on chassis and body
- Steering linkage and boots
- Transfer case oil
- Transmission fluid or oil
The gas guide marks the drive shaft boot and transfer case checks for 4WD models, and adds checking the propeller shaft boots (4WD models) and torquing the propeller shaft bolts. From the "Off-Road Daily Maintenance" pages of the 2026 4Runner and 4Runner i-FORCE MAX Warranty & Maintenance Guides.
Records, providers and your warranty
The guides say maintaining your vehicle according to their recommendations is required to keep your warranty coverage intact, and to keep detailed records: the date of service, the mileage and a description of the work. Toyota will not deny a warranty claim solely because you do not have records, but damage or failure caused by lack of proper maintenance is not covered under warranty.
Maintenance and repairs may be done by you or by any automotive service provider you choose, and Toyota will not deny a warranty claim solely because a provider other than a Toyota dealership did the work. A dealer may recommend more frequent intervals or more services than the chart lists; the guides say those additional services are not required to maintain warranty coverage, and to ask your dealer to explain any recommended maintenance not in the chart.

Toyota 4Runner maintenance FAQ
How often does a Toyota 4Runner need maintenance?
Toyota's 2026 4Runner and 4Runner i-FORCE MAX Warranty & Maintenance Guides both recommend scheduled maintenance every 5,000 miles or six months, whichever comes first. If you drive 5,000 miles in less than six months, go at 5,000 miles; if you have driven less than 5,000 miles at six months, go at six months.
How often should a 4Runner get an oil change?
Both 2026 guides list replacing the engine oil and oil filter every 10,000 miles or 12 months. A chart note says to replace both even when the maintenance reminder does not appear, after 12 months have passed or when driven over 10,000 miles since the last oil change. If the 4Runner is mainly driven on dirt or dusty roads, or on repeated trips of less than five miles in temperatures below freezing, the guides say to replace the oil and filter every 5,000 miles or 6 months.
When does a 4Runner need new spark plugs?
Both 2026 guides list replacing the spark plugs at 40,000, 80,000 and 120,000 miles. The guides note that spark plug maintenance is required under the terms of the Emission Control Warranty.
Is the 4Runner i-FORCE MAX maintenance schedule different?
Mostly not: the oil, tire rotation, filter, brake, differential, transfer case and propeller shaft intervals match. The i-FORCE MAX guide adds the HEV battery cooling intake filter (inspected at the 5,000-mile visits and cleaned every 20,000 miles) and the first inverter/intercooler coolant replacement (if applicable) at 150,000 miles/180 months, then every 50,000 miles/60 months.
How often should 4Runner differential and transfer case oil be changed?
Under normal driving, the charts list inspecting the front differential oil (if applicable) and rear differential oil every 15,000 miles and the transfer case oil (if applicable) every 30,000 miles. If most of your driving is towing a trailer, using a car-top carrier or heavy vehicle loading, the charts list replacing the front (if applicable) and rear differential oil every 15,000 miles and the transfer case oil (if applicable) every 30,000 miles; the transfer case oil is also replaced every 30,000 miles if you mostly drive on dirt or dusty roads.
When should 4Runner coolant be changed?
Both guides list the first engine/intercooler coolant replacement (if applicable) at 100,000 miles/120 months, then every 50,000 miles/60 months. The i-FORCE MAX guide also lists the first inverter/intercooler coolant replacement (if applicable) at 150,000 miles/180 months, then every 50,000 miles/60 months.
Do I have to service my 4Runner at a dealer to keep the warranty?
No. The guides say maintenance and repairs may be performed by you or by any automotive service provider you choose, and Toyota will not deny a warranty claim solely because you used a provider other than a Toyota dealership. Damage or failure caused by improper maintenance or repairs is not covered. Toyota also says to keep detailed records of each service.

Yes. Our service team in Streamwood can perform the services in Toyota's maintenance charts for your 4Runner or 4Runner i-FORCE MAX's mileage. See the service hours above or schedule online.
