FORD 2012 Flex v.1 - Manual (Page 79)

Do not use razor blades or other sharp objects to clean the inside
of the rear window or to remove decals from the inside of the
rear window. This may cause damage to the heated grid lines and
will not be covered by your warranty.
CABIN AIR FILTER
Your vehicle is equipped with a cabin air filter, located behind the glove
box. The particulate air filtration system is designed to reduce the
concentration of airborne particles such as dust, spores and pollen in the
air being supplied to the interior of the vehicle. This system provides the
following benefits:
• Improves driving comfort by reducing particle concentration.
• Improves the interior compartment cleanliness.
• Protects the climate control components from particle deposits.
Note: A cabin air filter must be installed at all times to prevent foreign
objects from entering the system. Running the system without a filter in
place could result in degradation or damage to the system.
For replacement intervals, refer to the Scheduled Maintenance chapter.
For more information regarding your filter, see your authorized dealer.
