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.
Use air conditioning to reduce
humidity and moisture inside the
vehicle on rainy or humid days.
During air conditioning system
operation, you may occasionally
notice a slight change in engine
speed as the air conditioning com-
pressor cycles. This is a normal
system operation characteristic.
Use the air conditioning system
every month only for a few minutes
to ensure maximum system per-
formance.
When using the air conditioning
system, you may notice clear water
dripping (or even puddling) on the
ground under the vehicle. This is a
normal system operation charac-
teristic. Operating the air conditioning sys-
tem in the recirculated air position
provides maximum cooling, how-
ever, continual operation in this
mode may cause the air inside the
vehicle to become stale.
During cooling operation, you may
occasionally notice a misty air flow
because of rapid cooling and
humid air intake. This is a normal
system operation characteristic.
System maintenance
Climate control air filter
The climate control air filter installed
behind the glove box filters the dust
or other pollutants that come into the
vehicle 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 accu-
mulation on the inside of the wind-
screen even when the outside (fresh)
air position is selected. If this hap-
pens, we recommend that the cli-
mate control air filter be replaced by
an authorised HYUNDAI dealer.

Information
• Replace the filter according to the
Maintenance Schedule.
If the vehicle is being driven in
severe conditions such as dusty or
rough roads, more frequent climate
control air filter inspections and
changes are required.
• When the air flow rate suddenly
decreases, we recommend that the
system be checked by an authorised
HYUNDAI dealer.
Air Conditioning refrigerant
label
The actual Air Conditioning refriger-
ant label in the vehicle may differ
from the illustration.The symbols and specifications on
the air conditioning refrigerant label
describe the:
1. Classification of refrigerant
2. Amount of refrigerant
3. Classification of Compressor lubri-
cant
You can find out which air condition-
ing refrigerant is applied to your vehi-
cle on the label located inside of the
bonnet. Refer to chapter 8 for the
location of the air conditioning refrig-
erant label.

Checking the amount of air
conditioner refrigerant and
compressor lubricant
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 an authorised
HYUNDAI dealer.
We recommend the air conditioning
system be serviced by an authorised
HYUNDAI dealer.

Vehicles equipped with R-134a
Because the refriger-
ant is at very high
pressure, the air con-
ditioning system
should only be serv-
iced by trained and certified
technicians. It is important that
the correct type and amount of
oil and refrigerant are used.
Otherwise, it may cause dam-
age to the vehicle and personal
injury.
WARNING
Vehicles equipped with
R-1234yf
Because the refriger-
ant is mildly inflam-
mable at very high
pressure, the air con-
ditioning system
should only be serv-
iced by trained and
certified technicians.
It is important that the
correct type and amount of oil
and refrigerant are used.
Otherwise, it may cause dam-
age to the vehicle and personal
injury.

For maximum defrosting, set the
temperature control to the extreme
right/hot position and the fan speed
control to the highest speed.
If warm air to the floor is desired
whilst defrosting or defogging, set
the mode to the floor-defrost posi-
tion.
Before driving, clear all snow and
ice from the windscreen, rear win-
dow, outside rear view mirrors, and
all side windows.
Clear all snow and ice from the
bonnet and air inlet in the cowl grill
to improve heater and defroster
efficiency and to reduce the proba-
bility of fogging up inside of the
windscreen.
Manual climate control system
To defog inside windscreen
1. Select any fan speed except “0”
position.
2. Select desired temperature.
3. Select the or position.
4. The outside (fresh) air will be select-
ed automatically. Additionally, the air
conditioning (if equipped) will auto-
matically operate if the mode is
selected to the position.
If the air conditioning and outside
(fresh) air position are not selected
automatically, press the correspon-
ding button manually.

Windscreen heating
Do not use the or posi-
tion during cooling operation in
extremely humid weather. The
difference between the temper-
ature of the outside air and that
of the windscreen could cause
the outer surface of the wind-
screen to fog up, causing loss
of visibility. In this case, set the
mode selection knob or button
to the position and fan
speed control knob or button to
lower speed.

Auto defogging system
(only for Automatic climate
control system, if equipped)
Auto defogging reduces the possibil-
ity of fogging up the inside of the
windscreen by automatically sensing
the moisture on the inside of the
windscreen.
The auto defogging system operates
when the heater or air conditioning is
on.When the Auto Defogging
System operates, the indi-
cator will illuminate.
If high levels of moisture are sensed
in the vehicle, the Auto Defogging
System will operate in the following
order:
Step 1 : Outside air position
Step 2 :Operating the air conditioning
Step 3 : Blowing air toward the wind-
screen
Step 4 : Increasing air flow toward
the windscreen
If the air conditioning is off or recircu-
lated air position is manually selected
whilst Auto Defogging System is ON,
the "ADS OFF" symbol Indicator will
blink 3 times to signal that the manual
operation has been cancelled.
