recommended.
Prolonged operation of the heater in the
recirculated air position (without air
conditioning selected) can cause fogging of
the windshield and side windows and the
air within the passenger compartment will
become stale.
In addition, prolonged use of the air
conditioning with the recirculated air
position selected will result in excessively
dry air in the passenger compartment.
WARNING

[ Continued climate control system
operation in the recirculated air
position may allow humidity to
increase inside the vehicle which
may fog the glass and obscure
visibility.

[ Do not sleep in a vehicle with the air
conditioning or heating system on. It
may cause serious harm or death due
to a drop in the oxygen level and/or
body temperature.

[ Continued climate control system
operation in the recirculated air
position can cause drowsiness
or sleepiness, and loss of vehicle
control. Set the air intake control
to the outside (fresh) air position as
much as possible while driving.

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 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,
have the system 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 be 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.

WINDSHIELD DEFROSTING AND DEFOGGING
WARNING
Windshield heating
Do not use the
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 button to the
position
and fan speed control knob to a lower
speed.

[ For maximum defrost performance,
set the temperature control to the
highest temperature setting 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 the engine temperature is still cold
after starting, then a brief engine warm
up period may be required for the
vented air flow to become warm or hot.

CAUTION
Take the following precautions to
maintain optimal performance of the
detecting sensor:

[Never disassemble the detecting
sensor or sensor assembly, or apply
any impact on it.

[ If the detecting sensors have been
replaced or repaired, have your
vehicle inspected by an authorized
HYUNDAI dealer.

[ Never install any accessories or
stickers on the front windshield, or
tint the front windshield.

[ Exercise extreme caution to keep the
front view camera dry.

[ Never place any reflective objects
(for example, white paper, mirror)
over the dashboard. Any light
reflection may prevent Forward
Collision-Avoidance Assist from
functioning properly.

[ Do not place any objects near the
front windshield or install any
accessories on the front windshield.
It can affect the performance of the
defogging and defrosting function
of the climate control system, which
may prevent the Driver Assistance
systems from operating.

[ Do not apply license plate frame or
objects, such as a bumper sticker,
film or a bumper guard, near the
front radar cover.

[ Always keep the front radar and
cover clean and free of dirt and
debris.
Use only a soft cloth to wash the
vehicle. Do not spray pressurized
water directly on the sensor or
sensor cover.
[
If unnecessary force has been
applied to the radar or around the
radar, Forward Collision-Avoidance
Assist may not properly operate
even though a warning message
does not appear on the cluster.
Have the vehicle be inspected by an
authorized HYUNDAI dealer.

[ Use only genuine parts to repair or
replace a damaged front radar cover.
Do not apply paint to the front radar
