For normal heating operation, set the air flow
control to the floor ( ) position. (The "Fresh"
mode will be activated.)
For faster heating, the air intake control switch
should be set in the recirculate ( ) position.
If the windows fog up, set the air flow control to
the defrost ( ) position (The A/C will turn on
automatically and "Fresh" mode will be acti-
vated.)
For maximum heat, move the temperature con-
trol to "Warm".

Fresh
Recirculation
With the " " mode selected, air enters the
vehicle from outside and is heated or cooled
according to the other functions selected.
With the " " mode selected, air from within
the passenger compartment is drawn through
the heating system and heated or cooled ac-
cording to the other functions selected.
NOTE:o It should be noted that prolonged opera-
tion of the heating system in " " mode
will give rise to fogging of the wind-
shield and side windows and the air
within the passenger compartment will
become stale. In addition prolonged use
of the air conditioning with the " " mode
selected may result in the air within the
passenger compartment becoming ex-
cessively dry.
o When the ignition switch is turned "ON"
the air intake control switch will change
to " " mode in floor, floor-defrost and
defrost position. This is normal opera-
tion. But, the air intake control switch
will change to " " mode when the
ignition switch is turned "ON" with the
MAX A/C mode selected.

VENTILATION
B700A02A-AATBI-LEVEL HEATING
B710A01A-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 switch to the fresh
air ( ) position.
o Set the air flow control at the bi-level ( )
position.
o Adjust the fan speed control to the desired
speed.
o Set the temperature control between "Cool"
and "Warm".
B700A01NF-A
To operate the ventilation system:
o Set the air intake control to 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".
B710A02NF-AB730A01L-AAT
Operation Tipso To keep dust or unpleasant fumes from
entering the car through the ventilation sys-
tem, temporarily set the air intake control at
the position. Be sure to return the control
to the position when the irritation has
passed to keep fresh air in the vehicle. This
will help keep the driver alert and comfort-
able.
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 and fan speed to the desired posi-
tion, turn on the air conditioning system, and
adjust temperature control to desired tem-
perature.

AIR CONDITIONING SYSTEM
B740B03O-AATAir Conditioning Operation
CoolingTo use the air conditioning to cool the interior:
o Set the air flow control to the face ( ) position.
o Turn on the air conditioning switch by push-
ing in on the switch. The air conditioning
indicator light should come on at the same
time.
o Set the air intake control to the fresh air ( )
position.
B740A01S-AATAir Conditioning Switch
(If Installed)The air conditioning is turned on or off by
pushing the A/C button on the heating/air con-
ditioning control panel.
HNF2128-AB740B01NF-A
o Set the temperature control to "Cool". ("Cool"
provides maximum cooling. The tempera-
ture may be moderated by moving the con-
trol toward "Warm".)
o Adjust the fan control to the desired speed.
For greater cooling, turn the fan control to
one of the higher speeds or temporarily
select the recirculate ( ) position on the
air intake control.

B740C02O-AATDe-Humidified HeatingFor dehumidified heating:
o Set the air flow control to the face ( ) position.
o Turn on the air conditioning switch. The air
conditioning indicator light should come on at
the same time.
o Set the air intake control to the fresh air ( )
position.
o Adjust the fan control to the desired speed.
o For more rapid action, set the fan at one of
the higher speeds.
o Adjust the temperature control to provide the
desired amount of warmth.
B740C01NF-A
B740D02Y-AATOperation Tipso 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 conditioning off
to avoid the possibility of the engine over-
heating.
o During winter months or in periods when the
air conditioning is not used regularly, run the
air conditioning once every month for a few
minutes. This will help circulate the lubri-
cants and keep your system in peak oper-
ating condition.

B970C01NF-AATAutomatic OperationThe FATC (Full Automatic Temperature Con-
trol) system automatically controls heating and
cooling as follows:
1. Push the "AUTO" switch. The indicator light
will illuminate confirming that the Face, Floor
and/or Bi-Level modes as well as the blower
speed and air conditioner will be controlled
automatically.
And, the air conditioning will operate if ambi-
ent temperature is higher than 34.7°F(1.5°C)
and automatically turns off if the ambient
temperature drops below 33.08°F(0.6°C).2. Turn the "TEMP" knob to set the desired
temperature.
The temperature will increase to the maxi-
mum "HI" by turning the knob clockwise.
The temperature will decrease to the mini-
mum "LO" by turning the knob counter-
clockwise.
NOTE:If the battery has been discharged or dis-
connected, the temperature mode will reset
to Centigrade degrees.
This is a normal condition and you can
change the temperature mode from Centi-
grade to Fahrenheit as follows;
Press the "OFF" and "AUTO " button simul-
taneously for 3 seconds.
The display shows that the unit of tempera-
ture is adjusted to Centigrade or Fahrenheit

With the "Fresh" mode selected, air enters the
vehicle from the outside and is heated or cooled
according to the function selected.
With the "Recirculation" mode selected, air from
within the passenger compartment will be drawn
through the heating system and heated or
cooled according to the function selected.NOTE:o It should be noted that prolonged opera-
tion of the heating system in "recircula-
tion" mode will give rise to 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 "Re-
circulation" mode selected may result in
the air within the passenger compart-
ment becoming excessively dry.
o When the ignition switch is turned "ON"
the air intake control will change to " "
mode (regardless of switch position).
This is normal operation. The air intake
control operates in "AUTO" mode when
turning the ignition to the ON position if
the "AUTO" mode was used before shut-
ting off the engine.Recirculation mode :
Air from witin the passenger compartment will
be drawn through the heating system and heated
or cooled according to the function selected.
Exhaust gas cutoff mode :
Air enters the vehicle from the outside.
But if exhaust gas enters the vehicle from the
outside, the exhaust gas cutoff mode ( ) is
automatically converted to the ( ) mode, to
prevent exhaust gas from entering the vehicle.
NOTE:o It should be noted that prolonged opera-
tion of the heating system in recircula-
tion mode ( ) will give rise to misting
of the windshield and side windows and
the air within the passenger compart-
ment will become stale. In addition, pro-
longed use of the air conditioning with
the recirculation mode ( ) sele-cted
may result in the air within the passenger
compartment becoming excessively dry.
o When the ignition switch is turned "ON",
the air intake control will change to
"Fresh" mode (regardless of switch po-
sition). This is normal operation. The air
intake control operates in "AUTO" mode
when turning the ignition to the ON
position if the "AUTO" mode was used
before shutting off the engine.
