Air conditioning
HYUNDAI Air Conditioning Systems are
filled with R-1234yf refrigerant.
1. Start the engine. Push the air conditioning button.
2. Set the mode to the
position.
3. Set the air intake control to the outside air or recirculated air position.
4. Adjust the fan speed control and temperature control to maintain
maximum comfort.
NOTICE
When using the air conditioning system,
monitor the temperature gauge closely
while driving up hills or in heavy traffic
when outside temperatures are high.
Air conditioning system operation may
cause engine overheating. Continue to
use the fan but turn the air conditioning
system off if the temperature gauge
indicates engine overheating. Air conditioning system operation tips
[
If the v
ehicle 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.

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.
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,
the system is 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.

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.
Automatic Climate Control
System
To defog inside windshield
OTM050116
1. Select the desired fan speed.
2. Select the desired temperature.
3. Press the defroster button (
).
4. The air-conditioning will turn on according to the detected ambient
temperature, outside (fresh) air
position and higher fan speed will be
selected automatically.
If the air-conditioning, outside (fresh)
air position and higher fan speed are
not selected automatically, adjust the
corresponding button or knob manually.
If the
position is selected, lower fan
speed is controlled to higher fan speed.
