Air ventilation seats (if equipped)
The air ventilation seats are provided
to cool the front seats by blowing air
through small vent holes on the sur-
face of the seat cushions and seat-
backs.
When the operation of the air ventila-
tion seats are not needed, keep the
switches in the OFF position.
While the engine is running, push the
switch to cool the driver's seat or thefront passenger's seat. Each time you push the switch, the
airflow changes as follows:
The air v entilation seats def ault to
the OFF position whenever the
ignition switch is turned to the ONposition.
To prevent damage to the air ven-tilation seat system and seats:
Use the air ventilation seats ONLY when the air conditioning
is on. Using the air ventilation
seats for prolonged periods oftime with the air conditioning offcould cause the air ventilationseats to malfunction.
(Continued)(Continued)
Never use a solvent such as
paint thinner, benzene, alcohol
or gasoline to clean the seats.
Avoid spilling liquids on the sur- face of the front seats and seat-
backs; this may cause the air
vent holes to become blocked
and not work properly.
Do not place materials such as plastic bags or newspapers
under the seats. They may blockthe air intake causing the air
vents to not work properly.
Do not change the seat covers. It may damage the air ventilationseats.
If the air vents do not operate, restart the vehicle. If there is no
change, have your vehicle
inspected by an authorized
HYUNDAI dealer.

Information
Prolonged operation of the heater in
the recirculated air position (without
air conditioning selected) may cause
fogging of the windshield and side
windows and the air within the pas-
senger compartment may become
stale.
In addition, prolonged use of the air
conditioning with the recirculated air
position selected will result in exces-
sively dry air in the passenger com-
partment.Fan speed control
The fan speed can be set to the
desired speed by pushing the fan
speed control button.
The higher the fan speed is, the
more air is delivered.
Pressing the OFF button turns off the

Continued climate control system operation in the recir-
culated air position may allowhumidity to increase inside
the vehicle which may fog the
glass and obscure visibility.

system on. It may cause seri-ous harm or death due to a
drop in the oxygen level
and/or body temperature.
Continued climate control system operation in the recir-culated air position can cause
drowsiness or sleepiness,
and loss of vehicle control.
