Information
Using the system in the fresh air position is
recommended.
Prolonged operation of the heater in the
recirculated air position (without air
conditioning selected) can cause fogging of
the windshield and side windows and the
air within the passenger compartment will
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 recirculated 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 serious harm or death due
to a drop in the oxygen level and/or
body temperature.
• Continued climate control system
operation in the recirculated 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.
Fan speed control
ONX4H050107
The fan speed can be set as desired by
pushing the fan speed control button.
Increased air flow is delivered with
higher fan speeds.
Pressing the OFF button turns off the fan.
NOTICE
Operating the fan when the ignition
switch is in the ON position could cause
the battery to discharge. Operate the
fan when the engine is running.

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.
• 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.
System maintenance
Cabin air filter
OIK047401L[A] : Outside air, [B] : Recirculated air
[C] : Cabin air filter, [D] : Blower
[E] : Evaporator core, [F] : Heater core
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.
We recommend that 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.

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.

Auto Defogging System
on Models with Automatic
Temperature Control
Auto defogging reduces the possibility of
fogging up the inside of the windshield
by automatically sensing the moisture on
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 14°F (-10°C).
To cancel or set the Auto Defogging
System, keep the front defroster button
pressed for 3 seconds. The “ADS OFF”
symbol will be shown in the climate
display to inform you that the system
is deactivated. To re-activate the auto
defogging system, follow the procedure
mentioned above and the “ADS OFF”
symbol will disappear.
If the battery has been disconnected
or discharged, it resets to the auto
defogging status.
Information
For efficiency, do not select recirculated
air position while the Auto defogging
system is operating.
NOTICE
Do not remove the sensor cover located
on the top of the windshield glass.
Damage to system parts could occur
and may not be covered by your vehicle
warranty.

CAUTION
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 12 volts electric accessories
which are less than 180 watts in
electric capacity.
• Adjust the air-conditioner or heater
to the lowest operating level when
using the power outlet.
• Close the cover when not in use.
• 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 electronic
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 electrical/
electronic devices with reverse
current protection. The current
from the battery may flow into the
vehicle’s electrical/electronic system
and cause system malfunction.
