Air conditioning system operation tips
• If the vehicle has been parked in
direct sunlight during hot weather,
open the windows for a short time
to let the hot air inside the vehicle
escape.
• After sufficient cooling has been
achieved, switch back from the
recirculated air to the fresh outside air
position.
• To help reduce moisture inside of
the windows on rainy or humid
days, decrease the humidity inside
the vehicle by operating the air
conditioning system with the windows
and sunroof closed.
• Use the air conditioning system every
month for a few minutes to ensure
maximum system performance.
• If you operate the air conditioner
excessively, the difference between
the temperature of the outside air and
that of the windshield could cause
the outer surface of the windshield to
fog up, causing loss of visibility. In this
case, set the mode selection button to
the
position and set the fan speed
control knob to the lowest speed
setting.
System maintenance
Cabin air filter
OIK047401L[A] : Outside air, [B] : Recirculated air
[C] : Cabin 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 HYUNDAI
dealer according to the maintenance
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.

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 HYUNDAI dealer.
NOTICE
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
conditioning system in your vehicle
should only be serviced by trained and
certified technicians.
WARNING
Vehicles equipped with R-1234yf
Since the refrigerant is
mildly flammable and
operated at 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
are used.
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.

WINDSHIELD DEFROSTING AND DEFOGGING
WARNING
Windshield heating
Do not use the
position during
cooling operation in extremely humid
weather. The difference between the
temperature of the outside air and that
of the windshield could cause the outer
surface of the windshield to fog up,
causing loss of visibility could cause
an accident resulting in serious injury
or death. In this case, set the mode
selection button to the
position
and fan speed control knob to a lower
speed.
• For maximum defrost performance,
set the temperature control to the
highest temperature setting and
the fan speed control to the highest
setting.
• If warm air to the floor is desired while
defrosting or defogging, set the mode
to the floor-defrost position.
• Before driving, clear all snow and ice
from the windshield, rear window,
side view mirrors, and all side
windows.
• Clear all snow and ice from the
hood and air inlet in the cowl grill
to improve heater and defroster
efficiency and to reduce the
probability of fogging up the inside of
the windshield.
NOTICE
If the engine temperature is still cold
after starting, then a brief engine warm
up period may be required for the
vented air flow to become warm or hot.
