Maintenance
Passenger Compartment Air Filter
The filter reduces dust, pollen, and other
airborne irritants from outside air that is pulled
into the vehicle. The filter should be replaced as
part of routine scheduled maintenance.
See your dealer regarding replacement of
the filter.
Service
All vehicles have alabel underhood that
identifies the refrigerant used in the vehicle.
The refrigerant system should only be serviced
by trained and certified technicians. The
air conditioning evaporator should never be
repaired or replaced by one from asalvage
vehicle. It should only be replaced by
a
new evaporator to ensure proper and
safe operation.
During service, all refrigerants should be
reclaimed with proper equipment. Venting
refrigerants directly to the atmosphere
is harmful to the environment and may
also create unsafe conditions based on
inhalation, combustion, frostbite, or other
health-based concerns.
The air conditioning system requires
periodic maintenance.
