How often should the Highlander's cabin air filter be replaced?
2 Answers
The Highlander's cabin air filter should be replaced every 10,000 kilometers. If frequently driving in poor environmental conditions, it's recommended to replace it earlier to maintain better air quality inside the vehicle. To replace it, open the glove box, remove the suspension rods on both sides to detach the glove box. After removal, you'll see two clips on the cabin air filter cover - apply slight outward pressure to release them. Remove the filter cover to access and replace the cabin air filter. The Highlander is a large SUV from Toyota, measuring 4890mm in length, 1925mm in width, and 1715mm in height, with a wheelbase of 2790mm. It's equipped with a 3.5L V6 engine delivering up to 201kW of power, paired with a stepped 5-speed automatic transmission with manual shift mode.
I've been driving a Highlander for three years, and the air filter replacement really depends on your specific driving conditions. The manufacturer recommends changing it every year or 15,000 kilometers, but you need to be flexible with this. If you drive in northern cities with heavy smog or frequently travel on dusty construction sites, you might need to replace it every seven or eight months. In humid southern regions, you should also be cautious as the filter can easily grow mold and produce odors. Personally, I make it a habit to check the filter every two minor services—just open the glove compartment on the passenger side to inspect its condition. The filter isn't expensive but plays a crucial role, especially if you have kids at home. Regularly replacing it can significantly reduce dust and bacteria inhalation. Don’t wait until the air vents start smelling bad to take action.
