Information
Using the system primarily in Fresh mode
and Recirculation mode only when needed
is recommended for best results.
Prolonged operation of the heater in
Recirculation mode and without the A/C
ON can cause fogging of the windshield.
In addition, prolonged use of the A/C
ON in Recirculation mode may result in
excessively dry, dehumidified air in the
cabin.
WARNING
• Continued use of the climate control
system operation in Recirculation
mode for a prolonged period of
time may cause drowsiness to the
occupants in the cabin. This may lead
to loss of vehicle control which may
lead to an accident.
• Continued use of the climate control
system operation in Recirculation
mode with the A/C OFF may allow
humidity to increase inside the
cabin. This may cause condensation
to accumulate on the windshield and
obscure visibility.
• Do not sleep in your vehicle or
remain parked in your vehicle with
the windows up and either the
heater or the air conditioning ON for
prolonged periods of time. Doing so
may increase the levels of carbon
dioxide in the cabin which may lead
to serious injury or death.
Fan speed control
ODN8A059113
Turn the knob to the right to increase
the fan speed and airflow. Turn the knob
to the left to decrease fan speed and
airflow.
Setting the fan speed control knob to the
“0” position turns off the fan.
NOTICE
Operating the fan speed when the
ignition switch is in the ON position
could cause the battery to discharge.
Operate the fan speed when the engine
is running.
Air conditioning
ODN8059114
Push the A/C button to turn the system
on (indicator light will illuminate) and off.

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 only for a few minutes
to ensure maximum system
performance.
• If you operate 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 knob
or button to the
position and fan
speed control to the lower speed.
System Maintenance
Cabin air filter
OIK047401L[A] : Outside air, [B] : Recirculated air
[C] : Cabin air filter, [D] : Blower
[E] : Evaporator core, [F] : Heater core
The cabin air 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.
Have the cabin air filter 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
cabin air filter inspections and changes
are required.
If the air flow rate suddenly decreases,
the system should be checked at an
authorized HYUNDAI dealer.
Checking the amount of air
conditioner refrigerant and
compressor lubricant
When the amount of refrigerant is low,
the performance of the air conditioning
is reduced. Overfilling also reduces the
performance of the air conditioning
system.
Therefore, if abnormal operation is
found, have the system inspected by an
authorized HYUNDAI dealer.

When starting the vehicle in cold
weather using manual temperature
control, operate the system in the
following method to improve heating.
- T

urn off or lower the blower, right
after starting the engine.
• Allow the engine to warm up during this
time since the air flow from the heater is
still cold.
- After a few minutes of engine warm
up, turn on or set the fan to a higher
level and adjust the temperature
setting to hot.

Fan speed control
ODN8H059319
The fan speed can be set to the desired
speed by using the fan speed control
toggle switch.
More air is delivered with higher fan
speeds.
Pressing the OFF button turns off the fan.
Information
For better sound quality, fan speed may
automatically slow down for a couple
of minutes when you activate voice
recognition or hands free.
NOTICE
Operating the fan when the ignition
switch is in the ON position could cause
the battery to discharge. Operate the
fan when the engine is running.

Cups or small beverages cups may be
placed in the cup holders.
WARNING
• Avoid abrupt starting and braking
when the cup holder is in use to
prevent spilling your drink. If hot
liquid spills, you could be burned.
Such a burn to the driver could cause
loss of vehicle control resulting in an
accident.
• Do not place uncovered or unsecured
cups, bottles, cans, etc., in the cup
holder containing hot liquid while
the vehicle is in motion. Injuries may
result in the event of a sudden stop
or collision.
• Only use soft cups in the cup holders.
Hard objects can injure you in an
accident.
WARNING
Keep cans or bottles out of direct sun
light and do not put them in a hot
vehicle. It may explode.
NOTICE
• Keep your drinks sealed while driving
to prevent spilling your drink. If liquid
spills, it may get into the vehicle’s
electrical/electronic system and

Wireless Cellular Phone
Charging System (if equipped)
ODN8059223
[A]: Indicator light, [B]: Charging pad
On certain models, the vehicle comes
equipped with a wireless cellular phone
charger.
The system is available when all doors
are closed, and when the ignition switch
is ON.
To charge a cellular phone
The wireless cellular phone charging
system charges only the Qi-enabled
cellular phones. Read the label on the
cellular phone accessory cover or visit
your cellular phone manufacturer’s
website to check whether your cellular
phone supports the Qi technology.
The wireless charging process starts
when you put a Qi-enabled cellular
phone on the wireless charging unit.
1.
R
emove other items, including the
smart key, from the wireless charging
unit. If not, the wireless charging
process may be interrupted. Place
the cellular phone on the center of
the charging pad (
).
2.

The indica

tor light is orange when
the cellular phone is charging. The
indicator light turns green when
phone charging is complete.
3.

Y

ou can turn ON or OFF the wireless
charging function in the user settings
mode on the instrument cluster. For
further information, refer to the “LCD
Display Modes” in this chapter.
If your cellular phone is not charging:
-

Sligh
tly change the position of the
cellular phone on the charging pad.
-

Mak
e sure the indicator light is
orange.
The indicator light will blink orange for 10
seconds if there is a malfunction in the
wireless charging system.
In this case, temporarily stop the
charging process, and re-attempt to
charge your cellular phone again.
The system warns you with a message
on the LCD display if the cellular phone
is still on the wireless charging unit after
the engine is turned OFF and the front
door is opened.
Information
For some manufacturers’ cellular phones,
the system may not warn you even though
the cellular phone is left on the wireless
charging unit. This is due to the particular
characteristic of the cellular phone and
not a malfunction of the wireless charging.
NOTICE
• The wireless cellular phone charging system may not support certain
cellular phones, which are not
verified for the Qi specification (
).
•

When placing y

our cellular phone
on the charging mat, position the
phone in the middle of the mat for
optimal charging performance. If
your cellular phone is off to the side,
the charging rate may be less and in
some cases the cellular phone may
experience higher heat conduction.
•

In some cases, the wir

eless charging
may stop temporarily when the
Remote Key or Smart Key is used,
either when starting the vehicle or
locking/unlocking the doors, etc.
•

When char

ging certain cellular
phones, the charging indicator
may not change to green when the
cellular phone is fully charged.
