[A]: Outside air, [B]: Recirculated air
[C]: Climate control air filter, [D]: Blower
[E]: Evaporator core, [F]: Heater core
The cabin air 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.
We recommend that the cabin air filter 
be replaced by an authorized retailer of 
Genesis Branded products according to 
the maintenance schedule. If the vehicle 
is being driven in severe conditions such 
as dusty or rough roads, more frequent 
cabin air filter inspections and changes 
are required.
If the air flow rate suddenly decreases, 
we recommend that the system be 
inspected at an authorized retailer of 
Genesis Branded products.
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 reduces the 
performance of the air conditioning 
system.
Therefore, if abnormal operation is 
found, we recommend that the system 
be inspected by an authorized retailer of 
Genesis Branded products.
NOTICE
It is important that the correct type and 
amount of oil and refrigerant are used. 
Otherwise, damage to the compressor 
and abnormal system operation may 
occur. To prevent damage, the air 
conditioning system in your vehicle 
should only be serviced by trained and 
certified technicians.
 WARNING
Vehicles equipped with R-134a
Since the refrigerant is 
operated at very high pressure, 
the air conditioning system 
should only be serviced 
by trained and certified 
technicians.
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.
