When using the air conditioning
system, monitor the engine tem-
perature gauge closely while driv-
ing up hills or in heavy traffic
when outside temperatures are
high. Air conditioning system
operation can cause engine over-
heating. Continue to use the blow-
er fan, but turn the air condition-
ing system off if the engine tem-
perature gauge indicates engine
overheating.
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.
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 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
replaced by an authorized HYUNDAI
dealer according to the maintenance
schedule. If the car is being driven in
severe conditions such as dusty or
rough roads, more frequent air condi-
tioner 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
has a negative influence on 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.
The air conditioning system should
be serviced by an authorized
HYUNDAI dealer.

Because the refriger-
ant is mildly inflam-
mable at very high
pressure, the air con-
ditioning 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.

Continued use of the climate
control system operation in
the recirculated air position
can cause drowsiness or
sleepiness, that may cause
loss of vehicle control result-
ing in an accident. Set the air
intake control to the outside
(fresh) air position as much as
possible while driving.
Continued use of the climate
control system operation in
the recirculated air position
(without the air conditioning
selected) 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 seri-
ous injury or death due to a
drop in the oxygen level
and/or body temperature.
