Information
 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
overheating. Continue to use the
blower fan but turn the air condi-
tioning system off if the temperature
gauge indicates 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 elec-
trical equipment, air conditioning
should only be used with the win-
dows closed.Air conditioning system operation
tips
If the vehicle has been parked indirect sunlight during hot weather,
open the windows for a short time
to let the hot air inside the vehicle
escape.
Use air conditioning to reduce humidity and moisture inside the
vehicle on rainy or humid days.
During air conditioning system operation, you may occasionallynotice a slight change in enginespeed as the air conditioning com-
pressor cycles. This is a normal
system operation characteristic.
Use the air conditioning system every month only for a few minutes
to ensure maximum system per-
formance.
When using the air conditioning system, you may notice clear water
dripping (or even puddling) on the
ground under the passenger side
of the vehicle. This is a normal sys-
tem operation characteristic. 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 characteristic.

System maintenance
Climate control air filter
The climate control air filter installed
behind the glove box filters the dustor other pollutants that come into the
vehicle from the outside through theheating 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
conditions such as dusty, rough
roads, more frequent climate con-
trol 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.
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 alsohas 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.

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 thatthe correct type and amount of
oil and refrigerant is used.
Otherwise, it may cause damage
to the vehicle and personal injury.

Air Conditioning refrigerant label
The actual Air Conditioning refrigerant
label in the vehicle may differ from the
illustration.The symbols and specifications on
the label refer to the following:
1. Classification of refrigerant
2. Amount of refrigerant
3. Classification of Compressor lubri-
cant

Defogging logic (if equipped)
To reduce the probability of fogging up the inside of the windshield, the
air intake or air conditioning are con-trolled automatically according to
certain conditions such as or
position. To cancel or return the
defogging logic, do the following.
1. Press the Engine Start/Stop but-ton to the ON position.
2. Press the defroster button ( ).
3. While pressing the air conditioning button (A/C), press the air intake
control button at least 5 times with-
in 3 seconds. The recirculation indicator will blink 3
times with 0.5 seconds of interval. It
indicates that the defogging logic is
canceled or returned to the pro-
grammed status.
If the battery has been discharged or
disconnected, it resets to the defog
logic status.

Automatic Ventilation (if equipped)
When the ignition is ON or when the
engine is running and the outside
temperature is below 15°C (59°F),
the automatic ventilation feature will
activate if the recirculated air intake
position is selected for more than 5
munutes. In this condition the air
intake position will automatically
switch to the outside (fresh) air
intake position.
To cancel or reset the Automatic
Ventilation
When the air conditioning system is
on, select Face Level mode and
while pressing the A/C button, press
the recirculated air position button
five times within three seconds.
Sunroof Inside Air
Recirculation (if equipped)
When the heater or air conditioning system is on with the sunroofopened, the outside (fresh) air posi-
tion will be automatically selected. At
this time, if you press the recirculated
air position button, the recirculated
air position will be selected but will
change back to the outside (fresh) air
position after 3 minutes. When the sunroof is closed, the air
intake position will return to the orig-
inal position that was selected.

InformationAn inappropriately disposedbattery can be harmful to the
environment and human
health. Dispose the battery
according to your local law(s)
or regulations.
To prevent damage to your vehi-
cle:
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 totouch.
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.
Information
Your vehicle has a battery in the trunk
compartment.

Maintenance
Owner maintenance schedule
When you stop for fuel:
Check the engine oil level.
Check coolant level in the enginecoolant reservoir.
Check the windshield washer fluid level.
Check for low or under-inflated tires.
While operating your vehicle:
Note any changes in the sound ofthe exhaust or any smell of
exhaust fumes in the vehicle.
Check for vibrations in the steering wheel. Notice if there is any
increased steering effort or loose-
ness in the steering wheel, or
change in its straight-ahead posi-tion.
Notice if your vehicle constantly turns slightly or "pulls" to one side
when traveling on smooth, levelroad.
When stopping, listen and check for unusual sounds, pulling to one
side, increased brake pedal travel
or "hard-to-push" brake pedal.
If any slipping or changes in the operation of your transmission
occurs, check the transmission
fluid level.
Check the automatic transmission P (Park) function.
Check the parking brake.
Check for fluid leaks under your vehicle (water dripping from the air
conditioning system during or after
use is normal).
At least monthly:
Check coolant level in the enginecoolant reservoir.
Check the operation of all exterior lights, including the stoplights, turn
signals and hazard warning flashers.
Check the inflation pressures of all tires including the spare for tires
that are worn, show uneven wear,or are damaged.
Check for loose wheel lug nuts.
Be careful when checking your
engine coolant level when the
engine is hot. This may result in
coolant being blown out of theopening and cause serious
burns and other injuries.
