Features of your vehicle
Recirculated air position
With the recirculated air
position selected, air from
the passenger compart-
ment will be drawn through
the heating system and
heated or cooled according
to the function selected.
Outside (fresh) air position
With the outside (fresh) air
position selected, air
enters the vehicle from out-
side and is heated or
cooled according to the
function selected.✽NOTICE
Prolonged operation of the heater in
the recirculated air position (with-
out air conditioning selected) may
cause fogging of the windshield and
side windows and the air within the
passenger compartment may
become stale.
In addition, prolonged use of the air
conditioning with the recirculated
air position selected will result in
excessively dry air in the passenger
compartment.WARNING
• Continued climate control
system operation in the recir-
culated air position may allow
humidity to increase inside
the vehicle which may fog the
glass and obscure visibility.
• Do not sleep in a vehicle with
the air conditioning or heating
system on. It may cause seri-
ous harm or death due to a
drop in the oxygen level
and/or body temperature.
• Continued climate control sys-
tem operation in the recirculat-
ed air position can cause
drowsiness or sleepiness, and
loss of vehicle control. Set the
air intake control to the outside
(fresh) air position as much as
possible while driving.

Air quality system
The air inflow from outside the vehi-
cle can be automatically controlled.
Press the button to activate the air
quality control system.
When using AQS mode, AQS(Air
Quality System) automatically sens-
es outdoor air pollutants and mini-
mizes them from entering the vehi-
cle, however, unpleasant or foul
odors that might be present may still
be noticeable within the vehicle.Exhaust gas cutoff mode :
Air enters the vehicle from the outside.
If exhaust gas enters the vehicle from
the outside, the exhaust gas cutoff
mode is automatically converted from
the outside air position to the recircu-
lated air position to prevent exhaust
gas from entering the vehicle.
✽NOTICE
It should be noted that prolonged
operation of the heating system in
recirculation mode will give rise to
misting of the windshield and side
windows and the air within the pas-
senger compartment will become
stale. In addition, prolonged use of
the air conditioning with the recir-
culation mode selected may result in
the air within the passenger com-
partment becoming excessively dry.
OVI043118
CAUTION
If the windows fog up with the
Recirculation or A.Q.S mode
selected, set the air intake con-
trol to the fresh air position or
A.Q.S control to OFF.

System operation
Ventilation
1. Set the mode to the position.
2. Set the air intake control to the
outside (fresh) air position.
3. Set the temperature control to the
desired position.
4. Set the fan speed control to the
desired speed.
Heating
1. Set the mode to the position.
2. Set the air intake control to the
outside (fresh) air position.
3. Set the temperature control to the
desired position.
4. Set the fan speed control to the
desired speed.
5. If dehumidified heating is desired,
turn the air conditioning system (if
equipped) on.
• If the windshield fogs up, set the
mode to the or press the front
defrost button ( ).Operation Tips
• To keep dust or unpleasant fumes
from entering the car through the
ventilation system, temporarily set
the air intake control to the recircu-
lated air position. Be sure to return
the control to the fresh air position
when the irritation has passed to
keep fresh air in the vehicle. This
will help keep the driver alert and
comfortable.
• Air for the heating/cooling system
is drawn in through the grilles just
ahead of the windshield. Care
should be taken that these are not
blocked by leaves, snow, ice or
other obstructions.
• To prevent interior fog on the wind-
shield, set the air intake control to
the fresh air position and fan speed
to the desired position, turn on the
air conditioning system, and adjust
the temperature control to desired
temperature.OVI043123

Features of your vehicle
Air conditioning
HYUNDAI Air Conditioning Systems
are filled with environmentally friend-
ly refrigerant.
1. Start the engine. Press the air con-
ditioning button.
2. Set the mode to the position.
3. Set the air intake control to the
outside air or recirculated air posi-
tion.
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 out-
side temperatures are high. Air
conditioning system operation
may cause engine overheating.
Continue to use the blower fan but
turn the air conditioning system
off if the temperature gauge indi-
cates engine overheating.
• When opening the windows in
humid weather air conditioning
may create water droplets inside
the vehicle. Since excessive water
droplets may cause damage to
electrical equipment, air condi-
tioning should only be run with
the windows closed.
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.
• 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.
• 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 passenger side
of the vehicle. This is a normal sys-
tem operation characteristic.
• 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 characteristics.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-
shield 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 authorized HYUNDAI dealer.
✽NOTICE
• Replace the filter according to the
Maintenance Schedule.
If the car is being driven in severe
conditions such as dusty, rough
roads, more frequent climate con-
trol air filter inspections and
changes are required.
• When the air flow rate suddenly
decreases, we recommend that the
system be checked by an author-
ized HYUNDAI dealer.

Features of your vehicle
Checking the amount of air
conditioner refrigerant and
compressor lubricant
When the amount of refrigerant is
low, the performance of the air condi-
tioning is reduced. Overfilling also
has a bad influence on the air condi-
tioning system.
Therefore, if abnormal operation is
found, we recommend that the sys-
tem be inspected by an authorized
HYUNDAI dealer.
WARNING - 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 is used.
Otherwise, it may cause damage
to the vehicle and personal injury.
