Air conditioning
All HYUNDAI Air Conditioning Systems
are filled with environmentally friendly
R-134a refrigerant which does not dam-
age the ozone layer.
1. Start the engine. Press the air condi-
tioning button.
2. Set the mode to the position.
3. Set the air intake control to the outside air or recirculated air position.
4. Adjust the fan speed control and tem- perature control to maintain maximum
comfort.
✽✽ NOTICE
 When using the air conditioning sys- tem, monitor the temperature gauge
closely while driving up hills or in
heavy traffic when outside tempera-
tures are high. Air conditioning sys-
tem operation may cause engine over-
heating. Continue to use the blower
fan but turn the air conditioning sys-
tem off if the temperature gauge indi-
cates engine overheating.
 When opening the windows in humid
weather air conditioning may create
water droplets inside the vehicle.
Since excessive water droplets may
cause damage to electrical equipment,
air conditioning should only be run
with the windows closed.
Air conditioning system operation tips
If the vehicle has been parked in directsunlight during hot weather, open the
windows for a short time to let the hot
air inside the vehicle escape.
To help reduce moisture inside of the windows on rainy or humid days,
decrease the humidity inside the vehi-
cle by operating the air conditioningsystem.
During air conditioning system opera- tion, you may occasionally notice aslight change in engine speed as the
air conditioning compressor cycles.
This is a normal system operation
characteristic.
Use the air conditioning system every month only for a few minutes to ensure
maximum system performance. When using the air conditioning sys-
tem, you may notice clear water drip-
ping (or even puddling) on the ground
under the passenger side of the vehi-
cle. This is a normal system operation
characteristic.
Operating the air conditioning system in the recirculated air position provides
maximum cooling, however, 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 opera-
tion characteristics.

WARNING
The air conditioning system should
be serviced by an authorized
HYUNDAI dealer. Improper service
may cause serious injury to the
person performing the service.
Climate control air filter (if equipped) The climate control air filter installed
behind the glove box filters the dust or
other pollutants that come into the vehi-cle 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 accumulation on the inside of
the windshield even when the outside
(fresh) air position is selected. If this hap-
pens, have the climate control air filter
replaced by an authorized HYUNDAI
dealer.
✽✽ NOTICE
 Replace the filter every 15,000 km (10,000 miles) or once a year.
If the car is being driven in severe
conditions such as dusty or rough
roads, more frequent air conditioner
filter inspections and changes are
required.
 When the air flow rate suddenly
decreases, the system should be
checked at an authorized HYUNDAI
dealer.Checking the amount of air con-
ditioner refrigerant and compres-sor lubricant
When the amount of refrigerant is low,
the performance of the air conditioning is
reduced. Overfilling also has a negativeimpact on the air conditioning system.
Therefore, if abnormal operation is
found, have the system 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. 1LDA5047

2. Select desired temperature.
3. Press the defrost button ( ).
4. The air conditioning will be turned on according to the detected ambient tem-
perature and outside (fresh) air posi-
tion will be selected automatically.
If the air conditioning and outside (fresh)air position are not selected automatical-
ly, adjust the corresponding button man-
ually. If the position is selected,
lower fan speed is adjusted to a higher
fan speed.
WINDSHIELD DEFROSTING AND DEFOGGING
WARNING - Windshield
heating
Do not use the or position during cooling operation in
extremely humid weather. The dif-
ference between the temperature ofthe outside air and that of the wind-shield could cause the outer sur-
face 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 lowerspeed.

If the position is selected, lower fan
speed is adjusted to a higher fan speed. Defogging logic
To reduce the probability of fogging up
the inside of the windshield, the air intakeor air conditioning are controlled auto-
matically according to certain conditions
such as or position. To cancel or
return the defogging logic, do the follow-ing.
1. Turn the engine start/stop button to theON position.
2. Press the defrost button ( ).
3. While pressing the air conditioning button (A/C), press the air intake con-
trol button at least 5 times within 3 sec-
onds.
The indicator of the air intake control but-
ton blinks 3 times with 0.5 second of
interval. It indicates that the defogging
logic is canceled or returned to the pro-
grammed status.
If the battery has been discharged or dis-
connected, it resets to the defog logic
status.

Auto defogging system (if equipped)
Auto defogging reduces the probability of
fogging up the inside of the windshield byautomatically sensing the moisture ofinside the windshield.This indicator illuminates
when the auto defoggingsystem senses the moistureof inside the windshield and
operates.
If more moisture is in the vehicle, the
higher steps operate as follow. For exam-
ple if auto defogging does not defoginside the windshield at step 1 Outside
air position, it tries to defog again at step
2 Blowing air toward the windshield.
Step 1 : Outside air positionStep 2 :Blowing air toward the windshield
Step 3 : Increasing air flow toward the windshield
Step 4 : Operating the air conditioning
Step 5 : Maximizing the air conditioning
✽✽ NOTICE
 If the A/C off or recirculated air posi- tion is manually selected while the
auto defogging system is on, the auto
defogging indicator will blink 3 times
to give notice that manual operation is
canceled.
 If the air quality system (AQS) is
selected while the auto defogging sys-
tem is operating at the step 1 outside
air position, the recirculated air posi-
tion may operate when the outside air
is polluted.

Driving your vehicle
Remember, your vehicle does notrequire extended warm-up. After the
engine has started, allow the engine to
run for 10 to 20 seconds prior to plac-
ing the vehicle in gear. In very cold
weather, however, give your engine a
slightly longer warm-up period.
Don't "lug" or "over-rev" the engine. Lugging is driving too slowly in too high
a gear resulting in the engine bucking.
If this happens, shift to a lower gear.
Over-revving is racing the engine
beyond its safe limit. This can be avoid-
ed by shifting at the recommended
speeds. Use your air conditioning sparingly.
The air conditioning system is operat-
ed by engine power so your fuel econ-
omy is reduced when you use it.
Open windows at high speeds can reduce fuel economy.
Fuel economy is less in crosswinds and headwinds. To help offset some of
this loss, slow down when driving in
these conditions.
Keeping a vehicle in good operating con-
dition is important both for economy and
safety. Therefore, have an authorized
HYUNDAI dealer perform scheduled
inspections and maintenance.
WARNING - Engine off dur-
ing motion
Never turn the engine off to coast
down hills or anytime the vehicle is
in motion. The power steering and
power brakes will not function
properly without the engine run-
ning. Instead, keep the engine on
and downshift to an appropriate
gear for engine braking effect. In
addition, turning off the ignition
while driving could engage the
steering wheel lock resulting in
loss of vehicle steering which
could cause serious injury ordeath.

IF THE ENGINE OVERHEATS
If your temperature gauge indicates over-
heating, you experience a loss of power,
or hear loud pinging or knocking, the
engine is probably too hot. If this hap-
pens, 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 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 coming out
from the hood, stop the engine. Do notopen 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 operat-
ing. If the fan is not running, turn the
engine off. 4. Check to see if the water pump drive
belt is missing. If it is not missing,
check to see that it is tight. If the drive
belt seems to be satisfactory, check for
coolant leaking from the radiator,
hoses or under the vehicle. (If the air
conditioning had been in use, it is nor-
mal for cold water to be draining from
it when you stop).
5. If the water pump drive belt is broken or 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 tem-
perature has returned to normal. 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 overheating. If over-heating happens again, call an author-
ized HYUNDAI dealer for assistance.
WARNING
While the engine is running, keep
hair, hands and clothing away from
moving parts such as the fan and
drive belts to prevent injury.
WARNING
Do not remove the radiator cap
when the engine is hot. This can
allow coolant to be blown out of the
opening and cause serious burns.
CAUTION
Serious loss of coolant indicates there is a leak in the cooling systemand this should be checked as soonas possible by an authorized HYUNDAI dealer.
