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.

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.

o Fading - As your car moves away from the
radio station, the signal will weaken and
sound will begin to fade. When this occurs,
we suggest that you select another stronger
station.
o Flutter/Static - Weak FM signals or large
obstructions between the transmitter and
your radio can disturb the signal causing
static or fluttering noises to occur. Reducing
the treble level may lessen this effect until the
disturbance clears.o Station Swapping - As an FM signal weak-
ens, another more powerful signal near the
same frequency may begin to play. This is
because your radio is designed to lock onto
the clearest signal. If this occurs, select
another station with a stronger signal.
o Multi-Path Cancellation - Radio signals being
received from several directions can cause
distortion or fluttering. This can be caused by
a direct and reflected signal from the same
station, or by signals from two stations with
close frequencies. If this occurs, select
another station until the condition has passed.
B750B04Y-AATUsing a cellular phone or a two-way radioWhen a cellular phone is used inside the vehicle,
noise may be produced from the audio equip-
ment. This does not mean that something is
wrong with the audio equipment. In such a case,
use the cellular phone at a place as far as
possible from the audio equipment.
WARNING:
Don't use a cellular phone when you are
driving. This could result in loss of control,
and an accident that may cause death,
serious injury, or property damage. You
must stop at a safe place to use a cellular
phone.

CAUTION:
o Shift into "R" and "P" position only when
the vehicle has completely stopped.
o Do not accelerate the engine in reverse
or any of the forward positions with the
brakes applied.
o Always apply the footbrake when shift-
ing from "P" or "N", to "R" or "D"position.
o Do not use the "P" (Park) position in
place of the parking brake. Always set
the parking brake, shift the transaxle
into "P" (Park) position and turn off the
ignition when you leave the vehicle, even
momentarily. Never leave the vehicle
unattended while the engine is running.
o When accelerating from a stop on a
steep hill, the vehicle may have a ten-
dency to roll backwards. Shifting the
shift lever into 2nd gear while in Sport
mode will help prevent the vehicle from
rolling backwards.
o Check the automatic transaxle fluid level
regularly, and add fluid as necessary.
o See the maintenance schedule for the
proper fluid recommendation.
C090H01L-GATNOTE:o For smooth and safe operation, depress
the brake pedal when shifting from "Neu-
tral" position or "Park" position to a
forward or reverse gear.

WARNING:
ABS (ESC) will not prevent accidents due to
improper or dangerous driving maneuvers.
Even though vehicle control is improved
during emergency braking, always main-
tain a safe distance between you and ob-
jects ahead. Vehicle speeds should always
be reduced during extreme road condi-
tions.
The braking distance for cars equipped
with an anti-lock braking system (ESC) may
be longer than for those without it in the
following road conditions.
During these conditions the vehicle should
be driven at reduced speeds:
o Rough, gravel or snow-covered roads.
o With tire chains installed.
o On roads where the road surface is pit-
ted or has different surface height.
The safety features of an ABS (ESC)
equipped vehicle should not be tested by
high speed driving or cornering. This could
endanger the safety of yourself or others.
ANTI-LOCK BRAKE SYSTEM (ABS)C120A03A-AAT(If Installed)The Anti-Lock Brake System (ABS) is designed
to prevent wheel lock-up during sudden braking
or on hazardous road surfaces. The ABS con-
trol module monitors the wheel speed and con-
trols the pressure applied to each brake. Thus,
in emergency situations or on slick roads, ABS
will increase vehicle control during braking.NOTE:During ABS (ESC) operation, a pulsation
may be felt in the brake pedal when the
brakes are applied. Also, a noise may be
heard in the engine compartment while
braking. These conditions are normal and
indicate that the anti-lock brake system
(Electronic Stability Control System) is func-
tioning properly.
Setting the driver's position1) Be sure the parking brake is engaged.
2) Move the accelerator and brake pedals to
the front most position by pushing the " "
portion of the switch.
3) Adjust the seat position and the steering
wheel angle properly.
4) Move the pedals toward you until you can
fully depress the brake pedal by pushing the
" " portion of the switch.
5) Depress the pedals a few times to get used
to the feel after adjusting.
WARNING:
o Adjust the pedals after parking the ve-
hicle on level ground. Never attempt to
adjust the pedals while the vehicle is
moving.
o Never adjust the pedals with your foot
on the accelerator pedal as this may
result in increasing the engine speed
and acceleration.
o Make sure that you can fully depress the
brake pedal before driving. Otherwise,
you may not be able to hold down the
brake pedal firmly in an emergency stop.
