Information
It should be noted that prolonged
operation of the heater in the recircu-
lated air position (without air condi-
tioning selected) will cause fogging of
the windscreen and side windows and
the air within the passenger compart-
ment will 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 ignition switch must be in the ON
position for fan operation.
The fan speed control knob allows
you to control the fan speed of the air
flowing from the ventilation system.
To change the fan speed, turn the
knob to the right for higher speed or
left for lower speed.

Convenient features of your vehicle
Continuous operation of the
climate control system in the
recirculated air position may
allow humidity to increase
inside the vehicle which may
fog the glass and obscure vis-
ibility.
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.
Continuous operation of the
climate control system in the
recirculated air position can
cause drowsiness or sleepi-
ness, and loss of vehicle con-
trol. Set the air intake control
to the outside (fresh) air posi-
tion 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 the 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 or R-1234yf
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.
Information
Your vehicle is filled with R-134a or
R-1234yf according to the regulation
in your country at the time of produc-
tion. You can find out which air condi-
tioning refrigerant is applied to your
vehicle on the label located inside of
the bonnet. Refer to chapter 8 for the
location of the air conditioning refrig-
erant label. 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) should never be
repaired or replaced with one
removed from a used or sal-
vaged vehicle and new replace-
ment MAC evaporators should
be certified (and labelled) as
meeting 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, the air condition-
ing should only be used with the
windows 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.
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.
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.
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 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.
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 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 or
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.

ant label in the vehicle may differ
