Where is the cabin air filter located on the Mercedes-Benz R320?
2 Answers
Mercedes-Benz R320's cabin air filter is located at the upper left corner of the engine compartment under the windshield. The cabin air filter is an important component of the vehicle's air conditioning system, which prevents external impurities from entering the AC system and affecting its normal operation. Additionally, the cabin air filter can purify the air to some extent, maintaining a relatively comfortable environment inside the vehicle. The Mercedes-Benz R320 measures 5159mm in length, 1922mm in width, and 1663mm in height, with a wheelbase of 3215mm. This vehicle meets consumers' demands for a multifunctional yet sporty driving experience, featuring fashionable yet understated design that demonstrates outstanding performance.
I remember when looking for the cabin air filter location on the Mercedes-Benz R320, it's right under the hood, directly in front of the windshield. Specifically, first open the hood, then look toward the base of the windshield where there's a black plastic cover or grille area covering the intake. You just need to gently pry open the clips or loosen a few screws to reveal the filter housing. This position is designed to allow air to be drawn directly into the AC system from here, so it tends to accumulate dust and leaves. Not replacing it for a long time can affect cabin air quality, reduce airflow, or cause odors. I change mine about every year and a half. The filter can be purchased at auto parts stores with matching models, and replacing it is very simple—no special tools needed. Just turn off the engine and wear gloves to keep clean before working. Mercedes' design for this location is quite user-friendly, much more convenient than those hidden behind the glove box. If unsure, check the owner's manual for detailed diagrams—once you do it, you'll get familiar with it.
