System Maintenance
Climate control air filter
This filter is installed behind the glove
box. It filters the dust or other pollu-
tants that enter the vehicle through theheating and air conditioning system.
Have the climate control air filter
replaced by an authorized HYUNDAIdealer according to the maintenance
schedule. If the car is being driven in
severe conditions such as dusty or
rough roads, more frequent air condi-tioner filter inspections and changesare required.
If the air flow rate suddenly decreas-
es, the system should be checked at
an authorized HYUNDAI dealer.
Checking the amount of air con-ditioner refrigerant and com-
pressor lubricant
When the amount of refrigerant is
low, the performance of the air con-
ditioning is reduced. Overfilling also
reduces the performance of the airconditioning system.
Therefore, if abnormal operation is
found, have the system inspected by
an authorized HYUNDAI dealer.
It is important that the correct type and amount of oil and refrig-
erant is used. Otherwise, damageto the compressor and abnormal
system operation may occur. To
prevent damage, the air condition-
ing system in your vehicle should
only be serviced by trained and
certified technicians.

Vehicles equipped with R-134a
Since the refrigerant
is operated at very
high pressure, the airconditioning system
should only be serv-
iced by trained and certified
technicians.
All refrigerants should be
reclaimed with proper equip-ment.
Venting refrigerants directly to the atmosphere is harmful to
individuals and environment.
Failure to heed these warningscan lead to serious injuries.
