To help reduce moisture inside ofthe windows on rainy or humid
days, decrease the humidity inside
the vehicle by operating the air
conditioning system with the win-
dows and sunroof closed.
Use the air conditioning system every month only for a few minutes
to ensure maximum system per-
formance.
If you operate 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 knob or button to
the position and fan speed
control to the lower speed.System Maintenance
Climate control air filter
This filter is installed behind the glove
box. It filters the dust or other pollu-
tants that enter the vehicle through the
heating and air conditioning system.
Have the climate control air filter be
replaced by an authorized HYUNDAI
dealer according to the maintenance
schedule. If the vehicle is being driv-
en in severe conditions such as
dusty or rough roads, more frequent
air conditioner filter inspections and
changes are required.
If the air flow rate suddenly decreas-
es, the system should be checked at
an authorized HYUNDAI dealer.
Checking the amount of air conditioner refrigerant andcompressor lubricant
When the amount of refrigerant is
low, the performance of the air con-
ditioning is reduced. Overfilling also
reduces the performance of the air
conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by
an authorized HYUNDAI dealer.
It is important that the correct
type and amount of oil and refrig-
erant is used. Otherwise, damage
to the compressor and abnormal
system operation may occur.

Air Conditioning refrigerant label
The actual Air Conditioning refriger-
ant label in the vehicle may differ
from the illustration.
Each symbols and specification on
air conditioning refrigerant label
means as below :
1. Classification of refrigerant
2. Amount of refrigerant
3. Classification of Compressor lubri- cant
Refer to chapter 8 for more detail
location of the air conditioning refrig-
erant label.
Because refrigerant
is flammable at very
high pressure, the air
conditioning 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 dam-
age to the vehicle and personal
injury.

For maximum defrosting, set thetemperature 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, 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 effi-
ciency and to reduce the probability
of fogging up the inside of the wind-
shield.
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.Manual Climate Control System
To defog inside windshield
1. Select any fan speed except "0" position.

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 on inside the wind-
shield.
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 50 °F (-10 °C).When the Auto Defogging
System operates, the indi-
cator will illuminate.
If high levels of moisture are sensed in
the vehicle, the Auto Defogging System
will operate in the following order:
Step 1: Outside air position
Step 2: Operating the air conditioning
Step 3: Blowing air toward the wind- shield
Step 4: Increasing air flow toward the windshield
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 ignition
switch is in the ON position. When the
Auto Defogging System is canceled,
the ADS OFF symbol will blink 3 times
and ADS OFF will be displayed on the
climate control information screen. When the Auto Defogging System is
reset, the ADS OFF symbol will blink
6 times without a signal.
Information
• When the air conditioning 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 the Auto
defogging system is operating.
• When Auto defogging mode is selected, fan speed, temperature and
intake mode which is adjusted man-
ually are canceled for better defog-
ging result.
Do not remove the sensor cover
located on the upper end of the
windshield glass.
Damage to system parts could
occur and may not be covered by
your vehicle warranty.

An inappropriately disposedbattery can be harmful to the
environment and human
health. Dispose of the battery
according to your local law(s)
or regulations.
To prevent damage to your vehicle:
Only use a 12-volt power supply (battery or jumper system) to
jump start your vehicle.
Do not attempt to jump start your vehicle by push-starting.
Jump starting procedure
1. Position the vehicles close enough that the jumper cables will reach,
but do not allow the vehicles to
touch.
2. Avoid fans or any moving parts in the engine compartment at all
times, even when the vehicles are
turned off.
3. Turn off all electrical devices such as radios, lights, air conditioning,
etc. Put the vehicles in P (Park)
and set the parking brakes. Turn
both vehicles OFF. 4. Connect the jumper cables in the
exact sequence shown in the illus-
tration. First connect one jumper
cable to the red, positive (+)

7. Connect the other end of the sec- ond jumper cable to the black,
negative (-) chassis ground of
your vehicle (4).
Do not allow the jumper cables to
contact anything except the cor-
rect battery or jumper terminals or
the correct ground. Do not lean
over the battery when making
connections.
8. Start the engine of the assisting vehicle and let it run at approxi-
mately 2,000 rpm for a few min-
utes. Then start your vehicle.
If your vehicle will not start after a
few attempts, it probably requires
servicing. In this event please seek
qualified assistance. If the cause of
your battery discharging is not
apparent, have your vehicle checked
by an authorized HYUNDAI dealer. Disconnect the jumper cables in the
exact reverse order you connected
them:
1. Disconnect the jumper cable from
the black, negative (-) chassis
ground of your vehicle (4).
2. Disconnect the other end of the jumper cable from the black, neg-
ative (-) battery/chassis ground of
the assisting vehicle (3).
3. Disconnect the second jumper cable from the red, positive (+)
battery/jumper terminal of the
assisting vehicle (2).
4. Disconnect the other end of the jumper cable from the red, positive
(+) jumper terminal of your vehicle
(1). If your temperature gage indicates
overheating, you experience a loss
of power, or hear loud pinging or
knocking, the engine may be over-
heating. 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 lever in P (Park) and set the parking brake. If the air
conditioning is ON, turn it OFF.
3. If engine coolant is running out under the vehicle or steam is com-
ing out from the hood, stop the
engine. Do not open the hood until
the coolant has stopped running
or the steaming has stopped. If
there is no visible loss of engine
coolant and no steam, leave the
engine running and check to be
sure the engine cooling fan is
operating. If the fan is not running,
turn the engine off.

4. Check for coolant leaking from theradiator, hoses or under the vehi-
cle. (If the air conditioning had
been in use, it is normal for cold
water to be draining from it when
you stop.)
5. If engine coolant is leaking out, stop the engine immediately and
call the nearest authorized
HYUNDAI dealer for assistance. 6. If you cannot find the cause of the
overheating, wait until the engine
temperature has returned to nor-
mal. Then, if coolant has been
lost, carefully add coolant to the
reservoir to bring the fluid level in
the reservoir up to the halfway
mark.
7. Proceed with caution, keeping alert for further signs of overheat-
ing. If overheating happens again,
call an authorized HYUNDAI deal-
er for assistance.
Serious loss of coolant indi-
cates a leak in the cooling sys-
tem and should be checked as
soon as possible by an author-
ized HYUNDAI dealer.
CAUTION
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.
WARNING
Your vehicle is
equipped with a
pressurized
coolant reserve
tank. NEVER
remove the
engine coolant
reservoir
tank/radiator cap or the drain
plug while the engine and radia-
tor are HOT. Hot coolant and
steam may blow out under pres-
sure, causing serious injury.
Turn the engine off and wait
until the engine cools down.
Use extreme care when remov-
ing the engine coolant reservoir
tank/radiator cap. Wrap a towel
or thick rag around it, and turn it
counterclockwise slowly to
release some of the pressure
from the system. Step back
while the pressure is released.
When you are sure all the pres-
sure has been released, contin-
ue turning the cap counter-
clockwise to remove it.
