Seat warmer (if equipped)
The seat warmer is provided to warm the
front seats during cold weather. With the
engine start/stop button in the ON position,
push either of the switches to warm the dri-
ver's seat or the front passenger's seat.
During mild weather or under conditions
where the operation of the seat warmer is
not needed, keep the switches in the
"OFF" position.
The temperature setting of the seat is
changed as follows :
✽ ✽ NOTICE
With the seat warmer switch in the LO
or HI position, the heating system in the
seat turns off or on automatically
depending on the seat temperature.
CAUTION
When cleaning the seats, do not
use an organic solvent such asthinner, benzene, alcohol or gaso- line. Doing so may damage thesurface of the heater or seats.
To prevent overheating the seat warmer, do not place anything onthe seats, that insulates against heat, such as blankets, cushionsor seat covers while the seatwarmer is in operation.
Do not place heavy or sharp objects on seats equipped withseat warmers. Damage to the seat warming components could occur.
WARNING- Seat warmer burns
Passengers should use extreme
caution when using seat warmers
due to the possibility of excess
heating or burns. The occupants
must be able to feel if the seat is
becoming too warm and to turn the
seat warmer off. The seat warmer
may cause burns even at low tem-
peratures, especially if used for
long periods of time. In particular,
the driver must exercise extreme
care for the following types of pas-
sengers:
1. Infants, children, elderly or dis-
abled persons, or hospital outpa-
tients
2. Persons with sensitive skin or those that burn easily
3. Fatigued individuals
4. Intoxicated individuals
5. Individuals taking medication that can cause drowsiness or
sleepiness (sleeping pills, cold
tablets, etc.)

(Continued)
A smaller-stature adult in the frontpassenger’s seat who is not seat-
ed correctly (for example: seat
excessively reclined, leaning on
the door or center console, or hips
shifted forward in the seat) can
cause a condition where the occu-
pant classification system senses
less weight than if the occupant
were seated properly (sitting
upright with the seatback in an
upright position, centered on the
seat cushion with their seat belt
on, legs comfortably extended
and their feet on the floor).
This condition can result in an
adult potentially being misclassi-
fied as a child and illumination of
the PASS AIR BAG "OFF" indica-
tor.(Continued)
Accident statistics show thatchildren are safer if they are
restrained in the rear, as opposed
to the front seat. It is recom-
mended that child restraints be
secured in a rear seat, including
an infant riding in a rear-facing
infant seat, a child riding in a for-
ward-facing child seat and an
older child riding in a booster
seat.
Air bags can only be used once – have an authorized HYUNDAI
dealer replace the air bag imme-
diately after deployment.
The occupant classification sys- tem may not work properly if
water, coffee or any other liquid
including rain gets on the seat.
Keep the front seat dry at all
times.
(Continued)(Continued)
If the PASS AIR BAG "OFF" indi-cator is illuminated when the
front passenger's seat is occu-
pied by an adult and he/she sits
properly (sitting upright with the
seatback in an upright position,
centered on the seat cushion
with their seat belt on, legs com-
fortably extended and their feet
on the floor), have that person sit
in the rear seat.
Do not modify or replace the front passenger seat. Don't place any-
thing on or attach anything such
as a blanket or seat heater to the
front passenger seat. This can
adversely affect the occupant
classification system.
Do not sit on sharp objects such as tools when occupying the
front passenger seat. This can
adversely affect the occupant
classification system.
Do not use accessory seat cov- ers on the front seats.

✽
✽NOTICE
Prolonged operation of the heater in the
recirculated air position (without air
conditioning selected) may cause fog-
ging of the windshield and side windows
and the air within the passenger com-
partment may become stale.
In addition, prolonged use of the air con-
ditioning with the recirculated air posi-
tion selected will result in excessively dry
air in the passenger compartment.
Fan speed control
The fan speed control button allows you
to control the fan speed of the airflow in
the vehicle.
To change the fan speed:
Press the up ( ) button to increase
fan speed.
Press the down ( ) button to decrease fan speed.
To turn off the fan speed, press the OFF
button.
WARNING
Continued use of the climate con- trol system operation in the recir-
culated 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 use of the climate con- trol system operation in the recir-
culated 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.

Features of your vehicle
Climate control air filter
The climate control air filter installed
behind the glove box filters the dust or
other pollutants that come into the vehi-
cle 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 accumulation on the inside of
the windshield even when the outside
(fresh) air position is selected. If this hap-
pens, have the climate control air filter
replaced by an authorized HYUNDAI
dealer.
✽ ✽NOTICE
• Replace the filter according to the
Maintenance Schedule.
If the vehicle is being driven in severe
conditions such as dusty, rough roads,
more frequent climate control air fil-
ter inspections and changes are
required.
• When the air flow rate suddenly decreases, the system should be
checked at an authorized HYUNDAI
dealer.
Checking the amount of air con-
ditioner refrigerant and compres-
sor lubricant
When the amount of refrigerant is low,
the performance of the air conditioning is
reduced. Overfilling also has a negative
influence on 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.
WARNING
The air conditioning system for the
Hybrid vehicle should be serviced
by an authorized HYUNDAI dealer.
The Hybrid air conditioning system
is connected to the high voltage
system and requires special fluids,
tools and service procedures.
Improperly servicing the Hybrid air
conditioning system could result in
electrical shock, serious injury, or
even death.
