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.
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.
Checking the amount of air
conditioner refrigerant and
compressor lubricant
When the amount of refrigerant is low,
the performance of the air conditioning
is reduced. Overfilling also reduces the
performance of the air conditioning system.
Therefore, if abnormal operation is found,
the system is inspected by an authorized
HYUNDAI dealer.
NOTICE
It is important that the correct type and
amount of oil and refrigerant is used.
Otherwise, damage to the compressor
and abnormal system operation may
occur. To prevent damage, the air
conditioning system in your vehicle
should only be serviced by trained and
certified technicians.

WINDSHIELD DEFROSTING AND DEFOGGING
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 (only
for Automatic Climate Control
System, if equipped)
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.

Information
The auto defogging system may not
operate normally, when the outside
temperature is below -10 °C (14 °F).
When the Auto Defogging
System operates, the indicator
will illuminate.
If a high amount of humidity is detected
in the vehicle, the Auto Defogging
System will be enabled. The following
will be performed automatically: - Air conditioning will turn ON.

- Air intake control will change to Fresh
mode.
- Mode will change to defrost to direct airflow to the windshield.
- Fan speed will increase accordingly.
If the air conditioning is off or

The power outlet is designed to provide
power for mobile telephones or other
devices designed to operate with vehicle
electrical systems. The devices should
draw less than 180 watts with the engine
running.
WARNING
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.
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.

If your temperature gauge indicates
overheating, you experience a loss of
power, or hear loud pinging or knocking,
the engine may be overheating. If this
happens, you should:
1. Pull off the road and stop as soon as it is safe to do so.
2. Place the shift button in P (Park) and set the parking brake
3. Make sure that there is no hot steam gushing out of the engine
compartment. When it is safe to do
so, open the engine compartment,
and check the water-pump connector.
When the water-pump connector is
disconnected, stop the engine, re-
connect the water-pump connector,
and then re-start the engine.
4. Set the temperature and the air flow to the maximum, and turn ON the air
conditioner.
WARNING
While the engine is running,
keep hands, clothing and tools
away from the moving parts
such as the cooling fan and
drive belt to prevent serious
injury. 5. When the Service warning light (
)
illuminates on the instrument cluster,
immediately stop the engine, and
we recommend that you contact an
authorized HYUNDAI dealer. When the
engine warning light (
) illuminates,
or when the coolant or hot steams
gush out of the engine compartment,
leave the engine compartment
opened, while running the engine.
This is to ventilate the engine
compartment and to cool down the
engine.
6. Check the coolant temperature gauge on the instrument cluster to
make sure the coolant temperature is
sufficiently cooled down. Check the
coolant level. When it is insufficient,
check its connection with the radiator,
the heater hose, and the water pump
for any leakage. When there is no
leakage, add the coolant. However,
if the problems persists, such as
the illumination of the warning
lights, leakages, or the cooling-fan
malfunction, which may overheat the
engine, immediately stop the engine,
and we recommend that the vehicle
checked by an authorized HYUNDAI
dealer.
