 "description": "Toyota's Grand Highlander maintenance schedule from its official guide: oil every 10,000 miles, filters at 30,000, plugs at 40,000, plus hybrid and warranty.",
 "quickAnswer": "Toyota's schedule for the Grand Highlander is a service visit every 5,000 miles or 6 months, with the engine oil and filter changed every 10,000 miles or 12 months. Cabin and engine air filters are replaced at 30,000 miles, spark plugs at 40,000 miles on the 2.4L turbo (then 80,000 and 120,000), and engine coolant first at 100,000 miles or 120 months, then every 50,000 miles or 60 months. All-wheel-drive gas trucks also replace the rear differential and transfer case oil every 30,000 miles. Hybrids add an HV battery cooling intake filter check at each visit and a cleaning every 20,000 miles. Dirt and dust shorten the oil interval to 5,000 miles or 6 months.",

 "content_markdown": "> QUICK ANSWER\n>\n> **Toyota's schedule for the Grand Highlander is a service visit every 5,000 miles or 6 months, with the engine oil and filter changed every 10,000 miles or 12 months.** Cabin and engine air filters are replaced at **30,000 miles**, spark plugs at **40,000 miles** on the 2.4L turbo (then 80,000 and 120,000), and engine coolant first at **100,000 miles or 120 months**, then every 50,000 miles or 60 months. All-wheel-drive gas trucks also replace the **rear differential and transfer case oil every 30,000 miles**. Hybrids add an **HV battery cooling intake filter** check at each visit and a cleaning every 20,000 miles. Dirt and dust shorten the oil interval to **5,000 miles or 6 months**.\n\nThe Grand Highlander's maintenance chart is spread across three pages of a 48-page booklet, with different footnotes for gas and hybrid trucks. This page puts it in one table, by mileage, from Toyota's own Warranty and Maintenance Guides.\n\n**Where these numbers come from.** The maintenance charts in Toyota's 2025 and 2026 Grand Highlander and 2025 Grand Highlander Hybrid Warranty and Maintenance Guides (publication numbers T-MMS-25GrandHighlander, T-MMS-25GrandHighlanderHV and T-MMS-26GrandHighlander). The 2025 and 2026 gas charts are identical. We read the 2024 guide's oil and tire-rotation intervals, which match, but we did not compare its other items line by line. Your own guide governs, and a dealer may recommend more based on inspection.\n\n## Every Visit: 5,000 Miles or 6 Months\n\n- **Rotate tires** at every 5,000 miles.\n- **Inspect all fluid levels,** wiper blades and the **brake linings and pads** (a visual check each 5,000 miles, thickness and disc runout every 30,000).\n- **Check the driver's floor mat installation.**\n- **Hybrids:** visually check the HV battery cooling intake filter for dirt and dust, and clean it if needed. Toyota says to clean it every 20,000 miles.\n\n## By Mileage\n\n| SERVICE | WHEN | NOTES |\n| --- | --- | --- |\n| Engine oil and filter | Every 10,000 mi or 12 months | Replace both after 12 months or 10,000 miles even if the reminder has not appeared |\n| Cabin air filter | 30,000, 60,000, 90,000 mi... | Replace sooner in heavy traffic, dust or desert driving |\n| Engine air filter | 30,000, 60,000, 90,000 mi... | Replace |\n| Spark plugs | 40,000, 80,000, 120,000 mi | Gas 2.4L turbo (T24A-FTS), and the hybrid chart lists plugs for the T24A-FTS only |\n| Automatic transmission fluid | Inspect at 30,000, 60,000, 90,000 mi... | Replace at 60,000 mi if you tow, load heavily, or do extensive idling and low-speed driving (taxi or delivery use) |\n| Rear differential oil (AWD gas) | Inspect 15,000, replace 30,000, inspect 45,000, replace 60,000 mi | Replace every 30,000 mi |\n| Transfer case oil (AWD gas) | Inspect 15,000, replace 30,000, inspect 45,000, replace 60,000 mi | Replace every 30,000 mi |\n| Engine and intercooler coolant | First at 100,000 mi or 120 months | Then every 50,000 mi or 60 months |\n| Ball joints, dust covers, brake lines and hoses, drive shaft boots, exhaust, steering gear and linkage | Inspect at 15,000, 30,000, 45,000 mi... | Every 15,000 miles |\n| Fuel lines, fuel tank band, vapor hoses and fuel tank cap gasket | Inspect at 30,000, 60,000, 90,000 mi... | Every 30,000 miles |\n| Drive belts | Inspect at 60,000, 75,000, 90,000 mi... | Gas chart. On hybrids the chart lists them for the T24A-FTS only |\n\n## Special Operating Conditions\n\nToyota says to do these extra items only if most of your driving is under the condition:\n\n- **Dirt or dusty roads:** change the oil and filter every **5,000 miles or 6 months**, inspect the engine air filter at every visit, and inspect ball joints, drive shaft boots and steering linkage more often.\n- **Towing, a car-top carrier or heavy loading:** torque the chassis and body nuts and bolts at every visit, torque the propeller shaft bolts, replace the rear differential and transfer case oil (gas AWD), and replace the automatic transmission fluid at 60,000 miles. Extensive idling and low-speed driving, as in taxi or delivery use, also triggers the 60,000-mile transmission fluid replacement.\n- **Road salt:** the chart adds propeller shaft bolt torque.\n\nTowing owners should read the [towing guide](/guides/toyota-grand-highlander-towing-capacity-by-engine/) for the ratings.\n\n## Oil Grade and Capacity\n\nThe gas and Hybrid MAX 2.4L turbo take **SAE 0W-20 (5.6 qt with filter)** and the 2.5L Hybrid takes **SAE 0W-8 (4.5 qt with filter)**. Details are in the [specs guide](/guides/toyota-grand-highlander-oil-tire-size-fluid-specs/).\n\n## Warranty at a Glance\n\n| COVERAGE | TERM |\n| --- | --- |\n| Basic warranty | 36 months or 36,000 miles |\n| Powertrain warranty | 60 months or 60,000 miles |\n| Hybrid system (Hybrid and Hybrid MAX) | 8 years or 100,000 miles |\n| Hybrid battery | 10 years or 150,000 miles |\n| Corrosion perforation | 60 months, any mileage |\n\nWhichever comes first applies to the mileage terms. Toyota's guide says the vehicle must be maintained to keep coverage intact, and that you may have the work done by a dealer or another service provider, and keep records. The emissions warranty covers spark plug service.\n\n## Gear\n\n*Links below are affiliate links: toyotadata earns a commission from VEVOR and, as an Amazon Associate, from qualifying Amazon purchases, at no extra cost to you.*\n\n| ITEM | USED FOR | BUY |\n| --- | --- | --- |\n| Toyota Genuine 0W-20 motor oil, 5 qt jug | Gas and Hybrid MAX (T24A-FTS) oil change, 5.6 qt with filter | [Shop on Amazon](https://www.amazon.com/s?k=Toyota+genuine+0W-20+motor+oil+5+quart&tag=1434042-20) |\n| Toyota Genuine 0W-8 motor oil | 2.5L Hybrid oil change, 4.5 qt with filter | [Shop on Amazon](https://www.amazon.com/s?k=Toyota+genuine+0W-8+motor+oil&tag=1434042-20) |\n| Grand Highlander engine air filter | 30,000-mile replacement.
