Fan Speed Control (Blower Control)
This is used to turn the blower fan on and off and
to select the fan speed.
The blower fan speed, and therefore the volume
of air delivered from the system, may be con-
trolled manually by setting the blower control
between the "1" and "4" position.

This control is used to adjust the degree of
heating or cooling desired.HLC2086For normal heating operation, set the air intake
control to the fresh air ( ) position and the
air flow control to the floor ( ) position.
For faster heating, the air intake control should
be set in the recirculate ( ) position.
If the windows fog up, set the air flow control to
the defrost ( ) position (The air conditioning
will be turned on automatically.) and the air
intake control to the fresh air ( ) position.
For maximum heat, move the temperature con-
trol to "Warm".
B700A01A-AAT
Your Hyundai is equipped with bi-level heating
controls. This makes it possible to have cooler
air from the dashboard vents and warmer air
from the floor outlets at the same time. To use
this feature:
o Set the air intake control to the fresh air
( ) position.
o Set the air flow control at the bi-level ( )
position.
o Set the temperature control between "Cool"
and "Warm".

Operation Tips
o To keep dust or unpleasant fumes from
entering the car through the ventilation
system, temporarily set the air intake con-
trol to the position.
Be sure to return the control to the po-
sition when the irritation has passed to keep
fresh air in the vehicle. This will help keep the
driver alert and comfortable.
o Air for the heating/cooling system is drawn in
through the grilles just ahead of the wind-
shield. Care should be taken that these are
not blocked by leaves, snow, ice or other
obstructions.
o To prevent interior fog on the windshield, set
the air intake control to the fresh air ( )
position, fan speed to the desired position,
turn on the air conditioning system, and
adjust temperature control to desired tem-
perature.

the A/C button on the heating/air conditioning
control panel.
B710A01A-AAT
To operate the ventilation system:
o Set the air intake control at the fresh air
( ) position.
o To direct all intake air to the dashboard
vents, set the airflow control to the face
( ) position.
o Adjust the fan speed control to the desired
speed.
o Set the temperature control between "Cool"
and "Warm".

o Turn on the fan control switch (1).
o Turn on the air conditioning switch (4) by
pushing in on the switch.
The air conditioning indicator light should
come on at the same time.
o Set the air intake control (5) to the po-
sition.
o Set the temperature control (3) to "Cool".
("Cool" provides maximum cooling. The tem-
perature may be moderated by moving the
control toward "Warm".)

Operation Tips
o If the interior of the car is hot when you first
get in, open the windows for a few minutes to
expel the hot air.
o When you are using the air conditioning
system, keep all windows closed to keep hot
air out.
o When moving slowly, as in heavy traffic, shift
to a lower gear. This increases engine speed,
which in turn increases the speed of the air
conditioning compressor.
o On steep grades, turn the air conditioner off
to avoid the possibility of the engine over-
heating.
o During winter months or in periods when the
air conditioner is not used regularly, run the
air conditioner once every month for a few
minutes. This will help circulate the lubri-
cants and keep your system in peak operat-
ing condition.

De-Humidified Heating
For dehumidified heating:
o Turn on the fan control switch (1).
o Turn on the air conditioning switch (4). The
air conditioning indicator light should come
on at the same time.
o Set the air intake control (5) to the fresh air
( ) position.
o Set the air flow control (2) to the face ( )
position.

control (1) to one of the higher speeds or
temporarily select the position on the
air intake control (5).o Adjust the fan control (1) to the desired
speed.
o For more rapid action, set the fan at one of
the higher speeds.

71DEFROSTING/DEFOGGING
NOTE:
When the A/C is operated continuously on the floor-defrost level ( ) or defrost level ( ), it may cause
fog to form on the exterior windshield. If this occurs, set the air flow control to the face level position
( ) and fan speed control to the low position.Use the heating/ventilation system to defrost or defog the
windshield:
To remove interior fog on the windshield:
o Set the air intake control to the fresh air ( ) position.
o Set the air flow control to the defrost ( ) position.
(The air conditioning will be turned on automatically.)
o Set the temperature control to the desired position.
o Set the fan speed control between "1" and "4" position.To remove frost or exterior fog on the windshield:
o Activate the windshield wipers and washer to remove
light frost and moisture.
o Set the air intake control to the fresh ( ) position.
o Set the air flow control to the defrost ( ) position.
(The air conditioning will be turned on automatically.)
o Set the temperature control to warm.
o Set the fan speed control to position "3" or "4".

7EMISSION CONTROL SYSTEMS
2EMISSION CONTROL SYSTEM
Canister
Fuel vapors generated inside the fuel tank are
absorbed and stored in the onboard canister.
When the engine is running, the fuel vapors
absorbed in the canister are drawn into the
induction system through the purge control so-
lenoid valve.
Purge Control Solenoid Valve (PCSV)
The purge control solenoid valve is controlled by
the Engine Control Module (ECM); when the
engine coolant temperature is low during idling,
the PCSV closes so that evaporated fuel is not
taken into the engine. After the engine warms-
up during ordinary driving, the PCSV opens to
introduce evaporated fuel to the engine.
H010B01A-AAT
1. CRANKCASE EMISSION CONTROL
SYSTEM
The positive crankcase ventilation system is
employed to prevent air pollution caused by
blow-by gases being emitted from the crank-
case. This system supplies filtered fresh air to
the crankcase through the air intake hose. In-
side the crankcase, the fresh air mixes with
blow-by gases, then passes through the PCV
valve into the induction system.
H010A01A-AAT
Your Hyundai is equipped with an emission
control system to meet all requirements of the
U.S. Environmental Protection Agency or Cali-
fornia Air Resources Board.
There are three emission control systems which
are as follows.
1) Crankcase Emission Control System
2) Evaporative Emission Control System
3) Exhaust Emission Control System
In order to ensure the proper function of the
emission control systems, it is recommended
that you have your car inspected and main-
tained by an authorized Hyundai dealer in ac-
cordance with the maintenance schedule in this
manual.
H010D01A-AAT3. EXHAUST EMISSION
CONTROL SYSTEM
The Exhaust Emission Control System is a
highly effective system which controls exhaust
emissions while maintaining good vehicle
performace.
H010C01S-AAT
2. Evaporative Emission Control (Includ-
ing ORVR: Onboard Refueling Vapor
Recovery) System
The Evaporative Emission Control System is
designed to prevent fuel vapors from escaping
into the atmosphere.
(The ORVR system is designed to allow the
vapors from the fuel tank to be loaded into a
canister while refueling at the gas station, pre-
venting the escape of fuel vapors into the atmo-
sphere.)
