3During 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 :✽ ✽ NOTICEWith the seat warmer switch in the LO
or HI position, the heating system in the
seat turns on or off automatically
depending on the seat temperature.
CAUTION
 When cleaning the seats, do not
use an organic solvent such asthinner, benzene, alcohol and gasoline. Doing so may damagethe surface of the heater or seats.
 To prevent overheating the seat warmer, do not place anything onthe seats that insulates againstheat, such as blankets, cushions or seat covers on the seats whilethe seat warmer 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

(Continued)
 Do not place an electronic device
such as a laptop computer on the
front passenger seat. Its elec-
tronic field may cause the OCS to
switch to the "on" condition and
thus allow the passenger air bag
to deploy needlessly in a colli-
sion, increasing your repair
costs.
 A smaller-stature adult in the front passenger’ seat who is not
seated 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
occupant 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)
 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.

4Air intake control This is used to select outside (fresh) air
position or recirculated air position.
To change the air intake control position,
push the control button. Recirculated air position
The indicator light on the
button illuminates when the
recirculated air position is
selected.
With the recirculated air position selected, air from
the passenger compart-
ment will be drawn through
the heating system and
heated or cooled according
to the function selected.
Outside (fresh) air position The indicator light on the
button will not illuminate
when the outside (fresh) air
position is selected.
With the outside (fresh) air
position selected, air enters
the vehicle from outside and
is heated or cooled accord-
ing to the function selected.
✽ ✽NOTICEProlonged 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 operation of the
air conditioning with the recirculated
air position selected will result in exces-
sively dry air in the passenger compart-
ment.

4Climate control air filterThe 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 lubricantWhen 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.✽ ✽ NOTICEIt 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.

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 controlThe fan speed can be set to the desired
speed by pushing the fan speed control
button.
To change the fan speed, press the right
of the button ( ) for higher speed, or
press the left of the button ( ) for lower
speed. To turn the fan speed control off,
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.

WARNING
Always check the surrounding
areas near your vehicle for people,
especially children, before putting a
car into D (Drive) or R (Reverse).
WARNING
- Driving under
the influence of alcohol or
drugs
Drinking and driving is dangerous.
Drunk driving is the number one
contributor to the highway death
toll each year. Even a small amount
of alcohol will affect your reflexes,
perceptions and judgment. Driving
while under the influence of drugs
is as dangerous or more dangerous
than driving drunk.
You are much more likely to have a
serious accident if you drink or
take drugs and drive.
If you are drinking or taking drugs,
don’t drive. Do not ride with a driv-
er who has been drinking or taking
drugs. Choose a designated driver
or call a cab.
KEY
WARNING
 When you intend to park or stop
the vehicle with the engine on, be
careful not to depress the accel-
erator pedal for a long period of
time. It may overheat the engine
or exhaust system and cause fire.
 When you make a sudden stop or turn the steering wheel rapidly,
loose objects may drop on the
floor and it could interfere with
the operation of the foot pedals,
possibly causing an accident.
Keep all things in the vehicle
safely stored.
 If you do not focus on driving, it may cause an accident. Be care-
ful when operating what may dis-
turb driving such as audio or
heater. It is the responsibility of
the driver to always drive safely.
