Climate Controls
CABIN AIR FILTER
The cabin air filter element 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. The presence of a particulate filter
element provides the following benefits:
• Improves your 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 regarding the cabin air filter, see the
scheduled maintenance information. For more information regarding
your filter, see your authorized dealer.
