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 heating and air condi-
tioning system.
We recommend that the climate con-
trol air filter be replaced by a
HYUNDAI authorised
according to the maintenance sched-
ule.
If the vehicle is being driven in
severe conditions such as dusty or
rough roads, more frequent climate
control filter
changes are required.
If the air flow rate suddenly decreas-
es, we recommend the system be
checked at a HYUNDAI authorised
repairer.
NOTICE
It is important that the correct
type and amount of oil and refrig-
erant is used. Otherwise, damage

to the compressor and abnormal

When the amount of refrigerant is
low, the performance of the air con-
ditioning is reduced. Overfilling also
reduces the performance of the air
conditioning system.
Therefore, if abnormal operation is
found, we recommend that the sys-
tem be inspected by a HYUNDAI
authorised repairer.
Vehicles equipped with R-134a
only be serviced by trained and
certified technicians. It is impor-
tant that the correct type and
amount of oil and refrigerant is
used. Otherwise, it may cause
damage to the vehicle and per-
sonal injury.
