• 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 characteristics.System maintenance
Climate control air filter
The climate control air filter installed
behind the glove box, filters the dust
or other pollutants that come into the
vehicle 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 accu-
mulation on the inside of the wind-
screen 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 authorised HYUNDAI dealer.
Information
• Replace the filter according to the
Maintenance Schedule.
If the vehicle is being driven in severe
conditions such as dusty, rough roads,
more frequent climate control air filter
inspections and changes are required.
• When the air flow rate suddenly
decreases, we recommend that the
system be checked by an authorised
HYUNDAI dealer.
Information
It is important that the correct type
and amount of oil and refrigerant is
used. Otherwise, damage to the com-
pressor and abnormal system opera-
tion may occur.

Information
Prolonged operation of the heater in
the recirculated air position (without
air conditioning selected) may cause
fogging of the windscreen and side
windows and the air within the passen-
ger compartment may become stale.
In addition, prolonged use of the air
conditioning with the recirculated air
position selected will result in exces-
sively dry air in the passenger com-
partment.
Fan speed control
The fan speed can be set to the
desired speed by pushing the fan
speed control button.
The higher the fan speed is, the
more air is delivered.
Pressing the OFF button turns off the
fan.
i
•Continued climate control
system operation in the recir-
culated air position 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 harm or death due to a
drop in the oxygen level
and/or body temperature.
•Continued climate control sys-
tem operation in the recirculat-
ed air position can cause
drowsiness or sleepiness, and
loss of vehicle control. Set the
air intake control to the outside
(fresh) air position as much as
possible whilst driving.

Operation Tips
• To keep dust or unpleasant fumes
from entering the vehicle through
the ventilation system, temporarily
set the air intake control to the
recirculated air position. Be sure to
return the control to the fresh air
position when the irritation has
passed to keep fresh air in the
vehicle. This will help keep the driv-
er alert and comfortable.
• Air for the heating/cooling system
is drawn in through the grilles just
ahead of the windscreen. Care
should be taken that these are not
blocked by leaves, snow, ice or
other obstructions.
• To prevent interior fog on the wind-
screen, set the air intake control to
the fresh air position and fan speed
to the desired position, turn on the
air conditioning system, and adjust
the temperature control to the
desired temperature.
Air conditioning
HYUNDAI Air Conditioning Systems
are filled with R-134a refrigerant.
1. Start the engine. Push the air con-
ditioning button.
2. Set the mode to the position.
3. Set the air intake control to the out-
side air or recirculated air position.
4. Adjust the fan speed control and
temperature control to maintain
maximum comfort.• The refrigerant system should
only be serviced by trained and
certified technicians to insure
proper and safe operation.
• The refrigerant system should
be serviced in a well-ventilated
place.
• The air conditioning evaporator
(cooling coil) shall never be
repaired or replaced with one
removed from a used or sal-
vaged vehicle and new replace-
ment MAC evaporators shall be
certified (and labelled) as meet-
ing SAE Standard J2842.

Information
• When using the air conditioning sys-
tem, monitor the temperature gauge
closely whilst 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 in
direct 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 occasionally
notice a slight change in engine
speed as the air conditioning com-
pressor cycles. This is a normal
system operation characteristic.
• Turn on 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 vehicle. This is a
normal system operation charac-
teristic.• 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.

occasionally notice a misty air flow

control air filter inspections and
changes are required.
• When the air flow rate suddenly
decreases, we recommend that the
system be checked by an authorised
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 also
has 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 authorised
HYUNDAI dealer.

• For maximum defrosting, set the
temperature control to the extreme
right/hot position and the fan speed
control to the highest speed.
• If warm air to the floor is desired
whilst defrosting or defogging, set
the mode to the floor-defrost posi-
tion.
• Before driving, clear all snow and
ice from the windscreen, rear win-
dow, outside rearview mirrors, and
all side windows.
• Clear all snow and ice from the
bonnet and air inlet in the cowl grill
to improve heater and defroster
efficiency and to reduce the proba-
bility of fogging up inside of the
windscreen.Manual climate control system
To defog inside windscreen
1. Select any fan speed except “0”
position.
2. Select the desired temperature.
3. Select the or position.
4. The outside (fresh) air will be select-
ed automatically. Additionally, the air
conditioning (if equipped) will auto-
matically operate if the mode is
selected to the position.
If the air conditioning and outside
(fresh) air position are not selected
automatically, press the correspon-
ding button manually.
WWINDSCREEN DEFROSTING AND DEFOGGING
Windscreen heating
Do not use the or posi-
tion during cooling operation in
extremely humid weather. The
difference between the temper-
ature of the outside air and that
of the windscreen could cause
the outer surface of the wind-
screen to fog up, causing loss
of visibility. In this case, set the
mode selection knob or button
to the position and fan
speed control knob or button to
lower speed.

Cigarette lighter (if equipped)
To use the cigarette lighter, the igni-
tion switch must be in the ACC or ON
position.
Push the cigarette lighter all the way
into its socket. When the element is
heated, the lighter will pop out to the
“ready” position.
We recommend that you use parts
for replacement from an authorised
HYUNDAI dealer.Only a genuine HYUNDAI lighter
should be used in the cigarette
lighter socket. The use of plug-in
accessories (shavers, hand-held
vacuums, and coffee pots, etc.)
may damage the socket or cause
electrical failure.
NOTICE
OLF044270R
•Do not hold the lighter in after
it is already heated because it
will overheat.
•If the lighter does not pop out
within 30 seconds, remove it
to prevent overheating.
•Do not insert foreign objects
into the socket of the cigarette
lighter. It may damage the cig-
arette lighter.
