1. Start the vehicle. Push the air
conditioning button.
Set the mode to the (
) position.
2. Set the air intake control to recirculation mode temporarily to
allow the cabin to cool quickly. When
the desired temperature in the cabin
is reached, change the air intake
control back to Fresh mode.
3. 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 production.
You can find out which air conditioning
refrigerant is applied to your vehicle on
the label located inside of the hood. Refer
to chapter 5 for the location of the air
conditioning refrigerant label.
NOTICE
• 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 salvaged
vehicle and new replacement MAC
evaporators should be certified (and
labeled) as meeting SAE Standard J2842.
NOTICE
When opening the windows in humid
weather air conditioning may create
water droplets inside the vehicle. Since
excessive water droplets may cause
damage to electrical equipment, air
conditioning 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.
• 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 windows
and sunroof closed.
• Use the air conditioning system every
month for a few minutes to ensure
maximum system performance.
• If you operate the 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 button
to the (
) position and set the fan
speed control knob to the lowest
speed setting.

This filter is installed behind the glove
box. It filters the dust or other pollutants
that enter the vehicle through the
heating and air conditioning system.
We recommend that the climate control
air filter be replaced by an authorized
HYUNDAI dealer according to the
maintenance schedule. If the vehicle is
being driven in severe conditions such
as dusty or rough roads, more frequent
climate control filter inspections and
changes are required.
If the air flow rate suddenly decreases,
we recommend the system be checked
at an authorized HYUNDAI dealer.
Information
• Replace the filter according to the Maintenance Schedule.
If the car 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 authorized
HYUNDAI dealer.

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 knob or button to lower speed. • For maximum windshield defrosting,
set the temperature control knob to
the highest temperature setting and
the fan control knob to the highest fan
speed. Select the front defrost button
on the climate control display.

Do not let your parking brake freeze
Under some conditions your parking
brake can freeze in the engaged position.
This is most likely to happen when there
is an accumulation of snow or ice around
or near the rear brakes or if the brakes
are wet. When there is the risk that your
parking brake may freeze, temporarily
apply it with the shift lever in P (Park).
Also, block the rear wheels in advance,
so the vehicle may not roll. Then, release
the parking brake.
Do not let ice and snow accumulate
underneath
Under some conditions, snow and ice
can build up under the fenders and
interfere with the steering. When driving
in such conditions during the severe
winter, you should check underneath
the vehicle on a regular basis, to ensure
that the front wheels and the steering
components is unblocked.
Carry emergency equipment
In accordance with weather conditions,
you should carry appropriate emergency
equipment, while driving. Some of the
items you may want to carry include tire
chains, tow straps or chains, flashlight,
emergency flares, sand, shovel, jumper
cables, window scraper, gloves, ground
cloth, coveralls, blanket, etc.
Do not place objects or materials in the
motor compartment
Putting objects or materials in the motor
compartment may cause an vehicle
failure or combustion, because they may
block cooling the parts in the motor
compartment. Such damage will not be
covered by the manufacturer’s warranty.

between the MAX and the MIN marks on
the side of the coolant reservoir when
the parts in the motor compartment is cool.
If the coolant is low, we recommend
to have the vehicle inspected by an
authorized HYUNDAI dealer.
Use only designated coolant water for
electric vehicles, adding other types
of water or antifreeze can damage the
vehicle.
WARNING
Since specific coolant water (Blue color,
Low conductivity) is applied for electric
vehicles, replenishment of other
antifreeze or water may cause problems
to the vehicle.
WARNING
The electric motor for the
cooling fan may continue to
operate or start up when
the vehicle is not running and can cause serious
injury.
Keep hands, clothing and
tools away from the rotating
fan blades of the cooling fan.
The electric motor for the cooling
fan is controlled by vehicle coolant
temperature, refrigerant pressure and
vehicle speed. As the vehicle coolant
temperature decreases, the electric
motor will automatically shut off. This is a normal condition.
