Be mindful of the windows' status to ensure good airflow, which can be improved by setting the air circulation mode to recirculate or by opening the windows. Secondly, carefully inspect the engine's exhaust system for any leaks and promptly repair them to prevent exhaust fumes from entering the cabin. Additionally, the exhaust gas recirculation (EGR) system should be regularly checked to ensure it is functioning properly and to avoid any abnormal situations.

Another key area to focus on is the vehicle's seals. Ensure that they are intact to improve airtightness, thereby reducing the possibility of exhaust fumes entering the cabin. Furthermore, if any engine conditions indicate a malfunction, timely repairs are essential. Special attention is also needed when idling in poorly ventilated environments to avoid the risk of exhaust fumes entering the vehicle.
For older vehicles with a strong exhaust smell inside the cabin, the same methods apply, especially the inspection of seals and engine conditions. In addition to the aforementioned methods, cleaning the throttle body and engine carbon deposits, as well as using high-quality gasoline, can also be effective in addressing exhaust smell issues.
Addressing the issue of exhaust fumes entering the vehicle cabin requires timely detection and effective measures. Maintaining the vehicle's systems in good condition, conducting regular inspections, and ensuring proper ventilation can effectively reduce the intrusion of exhaust fumes, making the driving experience safer and more comfortable.
