This filter is installed behind the glove
box. It filters the dust or other pollutants
that enter the vehicle through the heating
and air conditioning system.
Have the climate control air filter
replaced by an authorized HYUNDAI
dealer according to the maintenance
schedule. If the car is being driven in
severe conditions such as dusty or rough
roads, more frequent air conditioner filter
inspections and changes are required.
If the air flow rate suddenly decreases,
the system should be checked at an
authorized HYUNDAI dealer.

Checking the amount of air
conditioner refrigerant and
compressor lubricant
When the amount of refrigerant is low,
the performance of the air conditioning is
reduced. Overfilling also has a negative
influence on the air conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by an
authorized HYUNDAI dealer.
NOTICE
It is important that the correct type
and amount of oil and refrigerant is
1LDA5047
used. Otherwise, damage to the com-
pressor and abnormal system opera-
tion may occur.
WARNING
Because the refrigerant
is at very high pressure,
the air conditioning
system should only be
serviced by trained and
certified technicians. It is important
that the correct type and amount of
oil and refrigerant is used, other-
wise damage to the vehicle and
personal injury may occur.
The air conditioning system should be
serviced by an authorized HYUNDAI
dealer.
