Dust filter
Nearly all dust particles and pollen are filtered out
before outside air enters the passenger compartment
through the air distribution system.
Notes:
Do not obstruct the air flow by placing objects on the air
flow–through exhaust slots below the rear window.
Also keep the air intake grille in front of windshield free
of snow and debris.
Important!
This vehicle is equipped with an air conditioner system
that uses R–134a (HFC: hydrofluorocarbon) as a
refrigerant. Repairs should always be performed by a
qualified technician, and refrigerant should be collected
in a recovery system for recycling.
