System maintenance

Climate control air filter
[A] : Outside air, [B] : Recirculated air
[C] : Climate control air filter, [D] : Blower
[E] : Evaporator core, [F] : Heater core
This filter is installed behind the glove
box. It filters the dust or other pollutants
that enter the vehicle through the heat-
ing and air conditioning system.
We recommend that the climate control
air filter be replaced by an authorized
HYUNDAI dealer according to the main-
tenance schedule. If the vehicle is being
driven in severe conditions such as dusty
or rough roads, more frequent climate
control filter inspections and changes are
required.
If the air flow rate suddenly decreases,
we recommend the system be checked
at an authorized HYUNDAI dealer.
i
Information
• Replace the filter according to the Main-
tenance Schedule.
• If the car is being driven in severe condi-
tions such as dusty, rough roads, more
frequent climate control air filter inspec-
tions and changes are required.
• When the air flow rate suddenly decreas-
es, we recommend that the system be
checked by 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 bad influ-
ence on the air conditioning system.
Therefore, if abnormal operation is
found, we recommend that the system
be inspected by an authorized HYUNDAI
dealer.
NOTICE
OIK047401L OIK047401L
It is important that the correct type and
amount of oil and refrigerant is used.
Otherwise, damage to the compressor
and abnormal system operation may
occur. To prevent damage, the air con-
ditioning system in your vehicle should
only be serviced by trained and certified
technicians.
WARNING
Vehicles equipped with R-134a
All refrigerants should be reclaimed
with proper equipment.
Venting refrigerants directly to the
atmosphere is harmful to individuals
and environment. Failure to heed these
warnings can lead to serious injuries.
Since the refrigerant is oper-
ated at very high pressure,
the air conditioning system
should only be serviced by
trained and certified techni-
cians.
