Yes. In most Scion xB models sold in the United States, a cabin air filter is used to clean the air that enters the HVAC system. It is standard on the second-generation xB (2007–2014/2015) and not universally present on the first-generation models (2004–2006).
The cabin air filter helps prevent dust, pollen, and pollutants from entering the interior through the HVAC system. In most second-generation xBs, the filter sits in a rectangular housing behind the glove box, and replacement intervals are typically driven by the manual or maintenance schedule. If you own a first-generation xB, consult the owner's manual or a dealer to confirm whether a cabin air filter was installed for your year and trim, as configurations can vary by market.
Generation-by-generation overview
The following overview explains, by generation, whether the cabin air filter is typically included and where to find it. This helps owners confirm presence and plan replacement.
First generation (2004–2006)
- Cabin air filter availability: Generally not standard for U.S. market xB models; some markets or trims may have differed.
- Access/Location: If equipped, the filter is usually behind the glove box or beneath a dash panel; consult the service manual for exact access.
- Replacement guidance: If present, follow the owner's manual or a service manual for removal and replacement.
For owners of the first generation, verify via the owner's manual or a dealer whether a cabin air filter was installed in your specific vehicle.
Second generation (2007–2014/2015)
- Cabin air filter presence: Standard equipment in typical U.S. market trims.
- Location: Behind the glove box; you may need to lower the glove box and remove a filter housing cover to access the filter.
- Replacement guidance: Replace at intervals recommended by Toyota/Scion (commonly 15,000–30,000 miles) or per the manual; use a compatible cabin air filter type (usually rectangular pollen/dust filter).
Regular replacement helps maintain HVAC efficiency and interior air quality for second-generation xB owners.
DIY quick guide to checking and replacing
If your xB has a cabin air filter, here is a quick, general process. Note that steps can vary by model year and trim; refer to the owner's manual for exact instructions.
- Open the glove box and remove contents.
- Support the glove box by squeezing its sides to allow it to drop down and expose the lower housing.
- Locate the filter housing cover inside the dash area behind the glove box and unclip or unscrew it.
- Remove the old filter, noting its orientation for the new one.
- Insert the new filter with the correct airflow direction indicated on the filter.
- Reattach the housing cover and reassemble the glove box.
If your vehicle lacks a cabin air filter, maintain HVAC performance by following general service intervals and keeping the intake area clean and unobstructed.
Summary
In summary, the Scion xB generally includes a cabin air filter in its second generation (2007–2014/2015) and may not have one in most first-generation models (2004–2006). If you’re unsure, check your owner’s manual or contact a dealer to confirm whether your specific year and trim include a cabin air filter and to obtain the correct replacement guidance.
Can a bad air filter cause a misfire?
In extreme cases, an engine will run very roughly when its air filter is too dirty. A driver may notice their vehicle's engine misfiring, vibrating excessively, stalling, or a combination of these symptoms when the engine's air filter is clogged.
What was the worst year for Scion xB?
While the Scion xB generally fares well in reliability, it's essential to be mindful of its problematic years - particularly 2006, 2008, and 2009. As with any used vehicle, a thorough pre-purchase inspection by a trusted mechanic is highly recommended.
Where is the air filter on a 2008 Scion xB?
And you're going to want to push in here. And here on both sides. You push in firmly. And then it will let you slide out the glove box and then it's going to be held on by a shock right over here.
Does a cabin air filter help with allergies?
Cabin air filters also help to reduce the amount of those allergens that can get into your vehicle. Pollen, dust and other allergens can build up in your filter during heavy pollen season, so you may need to change it sooner.
