The climate control system is equipped with a dust and pollen filter that collects
pollen, dust, and other debris in the air, and removes odors such as diesel exhaust
and tobacco. The Maintenance Minder
™ messages will let you know when to
replace the filter.
We recommend that you replace the dust and pollen filter sooner when using your
vehicle in areas with high concentrations of dust.
Dust and Pollen Filter
Dust and Pollen Filter
Using an air freshener may reduce the deodorizing
effect of the dust and pollen filter, and may reduce
its life.
If the air flow from the climate control system
deteriorates noticeably, and the windows fog up
easily, the filter may need to be replaced. Please
contact a dealer for replacement.
If You Don't Use the Climate Control System Regularly
To insure oil is circulated in the system, occasionally turn on the A/C or set the
defroster mode for several minutes with the engine idling.
