2000 Toyota Avalon Changing Cabin Filters

Your shop routinely changes vehicle oil, fuel and air filters and occasionally emission filters. But there is another important filter that is often forgotten – the “cabin” or “interior” filter.

Initially, these filters were offered only on the high-end luxury vehicles. Over the past few years, many more vehicles have been equipped with interior air filters. The filtration capabilities range from simple dust filters to nearly HEPA-grade systems with activated charcoal for odor control.

The importance of replacing these filters can vary depending upon the vehicle. On the high-end systems, failure to replace the filters can result in major damage to the interior blower motor and blower control unit. On other systems, a clogged filter will drastically reduce airflow but may take years to damage the blower system due to non-critical internal sealing.

Educate your customers about the importance of changing their cabin filter every 12,000 miles or yearly*. A fresh, clean filter will improve their vehicle’s air quality, HVAC system efficiency and help to avoid expensive repairs in the future. If a vehicle is less than five years old, there is a good chance it has one.

Toyota® introduced a high-efficiency cabin air filter in their 2000 model year Avalon XL® (dealer installed option on XL) and XLS vehicles. To replace the filter, follow the service procedure below.
