An engine air filter helps keep contaminants out of the engine's intake airflow. Many passenger vehicles do not have a dedicated dirty-air-filter dashboard light; some vehicles use a restriction indicator or service message instead. Confirm the symbol in the manual before assuming a replacement is due.
Follow the inspection and replacement schedule appropriate to your vehicle and driving conditions. A cabin air filter serves a different purpose, so poor airflow from dashboard vents should not automatically be attributed to the engine filter.
When contacting Cherry City Transmissions in Salem, identify the message and whether the concern involves engine performance or cabin ventilation.
