Trunk lid control switch
(if equipped)
The trunk lid control switch is used to
prevent unauthorized access to the
trunk.
• When the trunk lid control switch is
in the UNLOCK position ( ), the
trunk can be unlocked with the
trunk release button and the
remote key or smart key.
• When the trunk lid control switch is
in the LOCK position ( ), the
trunk can be unlocked with the
mechanical key of the remote key
or smart key.
•Yo u a n d y o u r p a s s e n g e r s
must be aware of the location
of the Emergency Trunk
Safety Release lever in this
vehicle and how to open the
trunk in case you are acciden-
tally locked in the trunk.
•NEVER allow anyone to occu-
py the trunk of the vehicle at
any time. If the trunk is par-
tially or totally latched and the
person is unable to get out,
serious injury or death could
occur due to lack of ventila-
tion, exhaust fumes and rapid
heat build-up, or because of
exposure to cold weather con-
ditions. The trunk is also a
highly dangerous location in
the event of a crash because it
is not a protected occupant
space but is a part of the vehi-
cle’s crush zone.

kept out of the reach of chil-
dren. Parents should teach
their children about the dan-
gers of playing in trunks.
•Use the release lever for
emergencies only.

Air intake control
This is used to select outside (fresh)
air position or recirculated air position.
To change the air intake control posi-
tion, press the control button.
Recirculated air position
With the recirculated air
position selected, air
from the passenger
compartment will be
drawn through the heat-
ing system and heated
or cooled according to
the function selected.
Outside (fresh) air position
With the outside (fresh)
air position selected, air
enters the vehicle from
outside and is heated or
cooled according to the
function selected.
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 windshield 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.
Setting the fan speed control knob to
the “0” position turns off the fan.
To turn off the fan
To turn off the fan, turn the fan speed
control knob to the "0" position.
•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
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
while driving.

Operation Tips
•To keep dust or unpleasant fumes
from entering the car through the
ventilation system, temporarily set
the air intake control to the recircu-
lated 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 driver alert and
comfortable.
•Air for the heating/cooling system
is drawn in through the grilles just
ahead of the windshield. Care
should be taken that these are not
blocked by leaves, snow, ice or
other obstructions.
•To prevent interior fog on the wind-
shield, 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 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.
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 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
ever y 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 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-
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 con-
ditions 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 authorized
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.
