Climate control air filter
(if equipped)
The climate control air filter installed
behind the glove box filters the dust or
other pollutants that come into the vehi-
cle from the outside through the heating
and air conditioning system. If dust or
other pollutants accumulate in the filter
over a period of time, the air flow from the
air vents may decrease, resulting in
moisture accumulation on the inside of
the windscreen even when the outside
(fresh) air position is selected. If this hap-
pens, we recommend that the climate
control air filter be replaced by a
HYUNDAI authorised repairer.
✽ NOTICE
• Replace the filter 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.
• When the air flow rate suddenly
decreases, we recommend that the
system be checked by a HYUNDAI
Heater core
authorised repairer.
