Convenient features of your vehicle
Air intake control
This is used to select outside (fresh)
air position or recirculated air position.
To change the air intake control posi-
tion, press the control button.
Recirculated air position
With the recirculated air
position selected, air
from the passenger
compartment will be
drawn through the heat-
ing 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
outside and is heated or
cooled according to the
function selected.
Information
It should be noted that prolonged
operation of the heater in the recircu-
lated air position (without air condi-
tioning selected) will cause fogging of
the windshield and side windows and
the air within the passenger compart-
ment will 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.

•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.
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-
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 con-
ditions such as dusty, 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 authorized
HYUNDAI dealer.
Information
It is important that the correct type
and amount of oil and refrigerant is
used. Otherwise, damage to the com-
pressor and abnormal system opera-
tion may occur.

Information
Prolonged operation of the heater in
the recirculated air position (without
air conditioning selected) may cause
fogging of the windshield and side win-
dows 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 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.

•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.

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
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.

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.

•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
while defrosting or defogging, set the
mode to the floor-defrost position.
•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 inside of the wind-
shield.
Manual climate control system
To defog inside windshield
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.
WWINDSHIELD DEFROSTING AND DEFOGGING
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 that
of the windshield could cause
the outer surface of the wind-
shield 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
windshield by automatically sensing
the moisture of inside the windshield.
The auto defogging system operates
when the heater or air conditioning is
on.
Information
The auto defogging system may not
operate normally, when the outside
temperature is below -10 °C.
When the Auto Defogging
System operates, the indi-
cator will illuminate.
If higher level of moisture are sensed
in the vehicle, the Auto Defogging
System will operate in the following
order:
Step 1 : Operating the air conditioning
Step 2 : Outside air position
Step 3 : Blowing air toward the wind-
shield
Step 4 : Increasing air flow toward
the windshield
Step 5 : Maximizing the air condi-
tioning
If the air conditioning is off or recircu-
lated air position is manually selected
while Auto Defogging System is ON,
the Auto Defogging System Indicator
will blink 3 times to signal that the
manual operation has been canceled.
To cancel or reset the Auto
Defogging System
Press the front windshield defroster
button for 3 seconds when the igni-
tion switch is in the ON position. The
front windshield defroster button indi-
cator will blink 3 times and the ADS
OFF will be displayed on the climate
control information screen.
Information
•When the airconditioning is turned
on by Auto defogging system, if you
try to turn off the air conditioning, the
indicator will blink 3 times and the air
conditioning will not be turned off.
• For efficiency, do not select recircu-
lated air position while Auto defog-
ging system is operating.
Do not remove the sensor cover
located on the upper end of the
driver side windshield glass.
Damage to system parts could
occur and may not be covered by
your vehicle warranty.

To prevent damage to the Power
Outlets :
•Use the power outlet only when
the engine is running and
remove the accessory plug after
use. Using the accessory plug
for prolonged periods of time
with the engine off could cause
the battery to discharge.
•Only use 12V electric acces-
sories which are less than 180
W(Watt) in electric capacity.
•Adjust the air-conditioner or
heater to the lowest operating
level when using the power out-
let.
•Close the cover when not in use.
(Continued)
(Continued)
•Some electronic devices can
cause electronic interference
when plugged into a vehicle’s
power outlet. These devices may
cause excessive audio static
and malfunctions in other elec-
tronic systems or devices used
in your vehicle.
•Push the plug in as far as it will
go. If good contact is not made,
the plug may overheat and the
fuse may open.
•Plug in battery equipped electri-
cal/electronic devices with
reverse current protection. The
current from the battery may
flow into the vehicle's electri-
cal/electronic system and cause
system malfunction.
NOTICE
Avoid electrical shocks. Do not
place your fingers or foreign
objects (pin, etc.) into a power
outlet or touch the power outlet
with a wet hand.
