After opening the glove compartment on the passenger side and removing the upper bracket, the cabin air filter of the E300 is located behind the glove compartment. Below are the detailed specifications of the Mercedes-Benz E300: 1. Exterior-wise, the extended version of the new Mercedes-Benz E-Class remains unchanged from the imported E-Class, with only slight adjustments made to the body length, width, and wheelbase to cater to the Chinese market. 2. For the interior, it features a dark gray color scheme paired with brown seats. The focal point on the dashboard is a large GPS navigation screen, with audio control buttons in the middle section and air conditioning control buttons at the lower part. 3. In terms of safety, once a potential accident risk is detected—such as severe oversteering, understeering, sudden steering movements, panic braking, or emergency braking—the relevant protective measures will be instantly activated: automatically closing the sunroof and side windows, tightening the seat belts, and adjusting the electric seats to a more suitable position, thereby reducing the impact force on the head and neck.

I enjoy tinkering with my car in my spare time. The cabin air filter for the E300 is located behind the glove compartment on the passenger side. Last time during maintenance, I replaced it myself. First, empty the glove compartment, then push both sides inward to remove it. There's a cover panel securing the filter inside. Removing the panel requires some finesse, otherwise the clips might break. The cabin air filter has upper and lower layers - just take both out and replace them with new ones. Before DIY, I recommend preparing a flashlight as the footwell area on the passenger side has poor lighting - make sure not to install it backward. This filter should be replaced every 6-12 months, otherwise you'll smell dust every time you turn on the AC.

As a veteran Mercedes owner with 7 years of experience, I can locate the cabin air filter position blindfolded. It's hidden deep inside the glove compartment, right above the passenger footwell. When replacing, first slide the passenger seat all the way back to create working space. The cover has three clips that must be pressed simultaneously for removal - applying even pressure is crucial. The OEM filter has airflow direction arrows on its side, which must be aligned with the new filter. Many people forget to reset the reminder light after replacement - remember to reset the 'air filter' option in the vehicle settings menu to complete the process.

The design of the E300's cabin air filter location is very reasonable, allowing replacement without professional tools. Open the glove compartment and look inside; it's located behind the back panel. Press the elastic clips on both sides of the cover towards the middle to remove it. There might be some leaf debris in the filter slot, so clean it out to prevent clogging. Note that there are two types: standard and activated carbon, with the latter offering better odor removal but costing 20% more. Owners with limited DIY skills can refer to the maintenance video tutorial on the Mercedes-Benz official website.

Replacing the air conditioning filter is considered a basic item. The E300's filter is hidden inside the glove compartment. It's recommended to perform this operation when the engine is cold to avoid burns. First, empty the glove box contents, then pinch both sides of the box and squeeze them towards the middle to allow the entire box to drop down. Use a T20 screwdriver to remove the panel screws, and you'll find two parallel filters behind the white cover. When installing, ensure the filter arrows point downward and gently insert them by holding the edges to avoid damaging the filtration layer. Replacing it once every spring is most reasonable.

I've studied the design of the E300, and the cabin air filter is located below the front passenger dashboard. To remove the glove box, no tools are needed – simply press both hands on the grooves at the bottom and push upwards to detach the hinges. There's a small pull tab on the dark plastic cover; pull it horizontally to remove the filter bracket. It's important to note that there's a significant difference in filter quality. The OEM filter has a PM2.5 filtration efficiency of up to 95%, while aftermarket parts may be less than 70%. Before the rainy season, it's advisable to check the filter's humidity level, as mold growth can breed bacteria and affect the respiratory system.
