Temperature conversion
If the battery has been discharged or
disconnected, the temperature mode
display will reset to Centigrade.
To change the temperature unit from °C
to °F or °F to °C :
- Automatic climate control system
Press the AUTO button for 3 seconds while pressing the OFF button.
- Instrument cluster
Go to User Settings → Other → Temperature Unit.
The temperature unit on both the cluster
LCD display and the climate control
screen will change.
Air intake control
This is used to select the outside (fresh)
air position or recirculated air position.
To change the air intake control position,
push the control button.
Recirculated air position
With the recirculated air
position selected, air from the
passenger compartment will
be drawn through the heating
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
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.

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.
NOTICE
It is important that the correct type and
amount of oil and refrigerant is used.
Otherwise, damage to the compressor
and abnormal system operation may
occur. To prevent damage, the air
conditioning system in your vehicle
should only be serviced by trained and
certified technicians.
WARNING
Vehicles equipped with R-1234yf
Since the refrigerant is mildly flammable and
operated at high pressure,
the air conditioning system
should only be serviced
by trained and certified
technicians. It is important
that the correct type
and amount of oil and
refrigerant are used.
All refrigerants should be reclaimed
with proper equipment.
Venting refrigerants directly to the
atmosphere is harmful to individuals
and environment. Failure to heed these
warnings can lead to serious injuries.

WinDshielD DeFrosting AnD DeFogging
WARNING
Windshield heating
Do not use the
or position
during cooling operation in extremely
humid weather. 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 could cause
an accident resulting in serious injury
or death. In this case, set the mode
selection knob or button to the

position and fan speed control knob or
button to a lower speed. • For maximum defrost performance,
set the temperature control knob
to the highest temperature setting
(rotated all the way to the right) and
the fan speed control to the highest
setting.
• If warm air to the floor is desired while
defrosting or defogging, set the mode
to the floor-defrost position.
• Before driving, clear all snow and ice
from the windshield, rear window,
side view mirrors, and all side
windows.
• Clear all snow and ice from the
hood and air inlet in the cowl grill
to improve heater and defroster
efficiency and to reduce the
probability of fogging up the inside of the windshield.
NOTICE
If you start the vehicle when the
weather is cold, more adequate way to
heat the cabin is described below.
1. Turn off or lower the blower, right
after engine starting, because
engine temperature is still low and
the air flow is cold.
2. After few minutes of engine warm up, turn the blower to low to medium
speed and set the temperature
control to Hot.

Floor Mat Anchor(s)
ALWAYS use the Floor Mat Anchors to
attach the front floor mats to the vehicle.
The anchors on the front floor carpet
keep the floor mats from sliding forward.
WARNING
Do not overlay additional mats or liners
over the floor mats. If using All Weather
mats, remove the carpeted floor mats
before installing them. Only use floor
mats designed to connect to the
anchors.
WARNING
The following must be observed when
installing ANY floor mat to the vehicle. • Ensure to remove a protective
film attached on the carpet
before attaching a floor mat on
the front floor carpet. Otherwise,
the floor mat may move freely on
the protective film and it could
result in unintentional braking or
accelerating.
• Ensure that the floor mats are
securely attached to the vehicle’s
floor mat anchor(s) before driving
the vehicle.
• Do not use ANY floor mat that cannot
be firmly attached to the vehicle’s
floor mat anchors.
• Do not stack floor mats on top of one
another (e.g. all-weather rubber mat
on top of a carpeted floor mat). Only
a single floor mat should be installed in each position.
IMPORTANT - Your vehicle was
manufactured with driver’s side floor
mat anchors that are designed to
securely hold the floor mat in place.
To avoid any interference with pedal
operation, HYUNDAI recommends that
the HYUNDAI floor mat designed for use
in your vehicle be installed.
