Maintenance
Climate Control System Maintenance
Air Conditioning
To ensure proper and safe operation, th e Society of Automotive Engineers (SAE
J2845) recommends that the refrigerant sy stem only be serviced by trained and
certified technicians.
Never repair or replace the air conditioning evaporator (cooling coil) with one
removed from a used or salvaged vehicle.
New replacement mobile air conditioning evaporators must be certified (and
labeled) as meeting SAE Standard J2842.
Dust and Pollen Filter
The climate control system is equipped wi th a dust and pollen filter that collects
pollen, dust, and other debris in the air. The Maintenance MinderTM 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.
1Climate Control System Maintenance
NOTICE
Vented refrigerant is harmful to the environment.
To avoid refrigerant from venting, never replace the
evaporator with one re moved from a used or
salvaged vehicle.
Refrigerant in your vehicle’ s air conditioning system is
flammable and can be igni ted during servicing if
proper procedures are not followed.
The air conditioner labe l is found under the hood:
