Information
Prolonged operation of the heater in
the recirculated air position (without
air conditioning selected) may cause
fogging of the windshield and side
windows and the air within the pas-
senger compartment may become
stale.
In addition, prolonged use of the air
conditioning with the recirculated air
position selected will result in exces-
sively dry air in the passenger com-
partment.Fan speed control
The fan speed can be set to the
desired speed by pushing the fan
speed control button.
The higher the fan speed is, the
more air is delivered.
Pressing the OFF button turns off the
fan.
i
Continued climate control system operation in the recir-
culated air position may allowhumidity 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 system operation in the recir-culated air position can cause
drowsiness or sleepiness,
and loss of vehicle control.
Set the air intake control tothe outside (fresh) air position
as much as possible whiledriving.

Push the OFF button of the front to
turn off the air climate control sys-
tem. However, you can still operate
the mode and air intake buttons as
long as the Engine Start/Stop buttonis in the ON position.
Economy air conditioning button (ECON)
If you push the ECON button while
the air conditioning system is work-ing, the air conditioning system will
work less and may improve fuel effi-
ciency.
If you want maximum air conditioning
turn the ECON system off by push-
ing the ECON button.

System maintenance
Climate control air filter
The climate control air filter installed
behind the glove box filters the dustor other pollutants that come into the
vehicle from the outside through theheating 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.Information
 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 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 con-
ditioning is reduced. Overfilling alsohas 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.

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 thatthe correct type and amount of
oil and refrigerant is used.
Otherwise, it may cause damage
to the vehicle and personal injury.

For maximum windshield defrost-
ing, set the temperature control
knob to the highest temperature
setting and the fan control knob to
the highest fan speed. Select the
front defrost button on the climate
control display. After the engine
warm-up period, warm air will bedirected to the front windshield.
If warm air to the floor is desired while defrosting or defogging, setthe mode to the floor-defrost posi-tion.
Before driving, clear all snow and ice from the windshield, rear win-
dow, outside rear 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 effi-ciency and to reduce the probabili-
ty of fogging up the inside of thewindshield.
To reduce tendency of the glass fogging and also to improve visibil-
ity, keep the interior surface of the
windshield clean by wiping it with a
clean cloth and glass cleaner. If the engine temperature is still
cold after starting, then a brief
engine warm up period may be
required for the vented air flow tobecome warm or hot.NOTICE
Windshield 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 thatof the windshield could causethe outer surface of the wind-
shield to fog up, causing loss ofvisibility could cause an acci-
dent resulting in serious injury
or death. In this case, set the
mode selection knob or button
to the position and fan
speed control knob or button to
a lower speed.
