Air conditioning system operation tips
If the vehicle has been parked in direct
sunlight 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 win- dows on rainy or humid days, decrease
the humidity inside the vehicle by oper-ating the air conditioning system.
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 if 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. D230300AFD-EA
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 authorised HYUNDAI
dealer.✽✽

Manual heating and air condition- ing The heating and cooling system can be
controlled manually by pushing buttons
other than the AUTO button. In this case,
the system works sequentially according
to the order of buttons selected.
When pressing any button except AUTO
button while automatic operation, thefunctions not selected will be controlled
automatically.
1. Start the engine.
2. Set the mode to the desired position.
3. Set the temperature control to the
desired position.
4. Set the air intake control to the outside (fresh) air position.
5. Set the fan speed control to the desired speed.
6. If air conditioning is desired, turn the air conditioning system on.
Press the AUTO button in order to con-
vert to full automatic control of the sys-tem. D240201ANF
Mode selection
The mode selection button controls the
direction of the air flow through the venti-lation system.
Refer to the illustration in the “Manual cli- mate control system”.
The air flow outlet port is converted as
follows: Face-Level (B, D)
Air flow is directed toward the upper body
and face. Additionally, each outlet can becontrolled to direct the air dischargedfrom the outlet.
Bi-Level (B, D, C, E)
Air flow is discharged towards the face and
floor.
Floor-Level (C, E, A, D)
Most of the air flow is directed to the
floor, with a small amount of the air beingdirected to the windshield and side win-
dow defroster.
Floor/Defrost-Level (A, C, E, D)
Most of the air flow is directed to the floorand the windshield with a small amount
directed to the side window defrosters.

Power outlet
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 10 amps with the engine
running.
CAUTION - Vanity mirror
lamp (if equipped)
Close the vanity mirror cover securely and return the sunvisor toits original position after use. If the vanity mirror is not closed securely,
the lamp will stay on and couldresult in battery discharge.
CAUTION
Use power outlet only when the
engine is running and remove theaccessory plug after use. Using the accessory plug for prolonged
periods of time with the engineoff could cause the battery to dis- charge.
Only use 12V electric accessories which are less than 10A in elec-
tric capacity.
Adjust the air-conditioner or heater to the lowest operatinglevel when using the power outlet.
Close the cover when not in use. Some electronic devices can cause electronic interferencewhen plugged into a vehicle’s power outlet. These devices maycause excessive audio static and
malfunctions in other electronicsystems or devices used in yourvehicle.

How car audio works
AM and FM radio signals are broadcast
from transmitter towers located around your
city. They are intercepted by the radio anten-
na on your car. This signal is then received
by the radio and sent to your car speakers.
When a strong radio signal has reached
your vehicle, the precise engineering of
your audio system ensures the best pos-
sible quality reproduction. However, in
some cases the signal coming to your
vehicle may not be strong and clear. This
can be due to factors such as the dis-
tance from the radio station, closeness of
other strong radio stations or the pres-
ence of buildings, bridges or other large
obstructions in the area.AM broadcasts can be received at
greater distances than FM broadcasts.
This is because AM radio waves are
transmitted at low frequencies. These
long, low frequency radio waves can fol-
low the curvature of the earth rather than
travelling straight out into the atmos-
phere. In addition, they curve around
obstructions so that they can provide bet-
ter signal coverage.
FM broadcasts are transmitted at high
frequencies and do not bend to follow the
earth's surface. Because of this, FM
broadcasts generally begin to fade at
short distances from the station. Also,
FM signals are easily affected by build-
ings, mountains, or other obstructions.
These can result in certain listening con-
ditions which might lead you to believe a
problem exists with your radio. The fol-
lowing conditions are normal and do not
indicate radio trouble:

WARNING - ENGINE EXHAUST CAN BE DANGEROUS!
Engine exhaust fumes can be extremely dangerous. If, at any time, you smell exhaust fumes inside the vehicle, open the win-
dows immediately.
• Do not inhale exhaust fumes.
Exhaust fumes contain carbon monoxide, a colourless, odourless gas that can cause unconsciousness and death by asphyx- iation.
The exhaust system should be checked whenever the vehicle is raised to change the oil or for any other purpose. If you hear
a change in the sound of the exhaust or if you drive over something that strikes the underneath side of the car, have the
exhaust system checked as soon as possible by an authorised HYUNDAI dealer.
Letting the engine idle in your garage, even with the garage door open, is a hazardous practice. Never run the engine in your
garage any longer than it takes to start the engine and back the car out.
If it is necessary to idle the engine for a prolonged period with people inside the car, be sure to do so only in an open area
with the air intake set at "Fresh" and fan operating at one of the higher speeds so fresh air is drawn into the interior.
If you must drive with the trunk open because you are carrying objects that make this necessary:
1. Close all windows.
2. Open side vents.
3. Set the air intake control at "Fresh", the air flow control at "Floor" or "Face" and the fan at one of the higher speeds.
To assure proper operation of the ventilation system, be sure the ventilation air intakes located just in front of the windshie ld are
kept clear of snow, ice, leaves or other obstructions.
