Warning Light Operation Warning Light OperationWarning Light Operation Warning Light Operation
Warning Light OperationThe parking brake/brake fluid level warning
light should come on when the parking brake is
applied and the ignition switch is turned to "ON"
or "START". After the engine is started, the light
should go out when the parking brake is re-
leased.
If the parking brake is not applied, the warning
light should come on when the ignition switch is
turned to "ON" or "START", then go out when
the engine starts. If the light comes on at any
other time, you should slow the vehicle and
bring it to a complete stop in a safe location off
the roadway.
The brake fluid level warning light indicates that
the brake fluid level in the brake master cylinder
is low and hydraulic brake fluid conforming to
DOT 3 or DOT 4 specifications should be
added. After adding fluid, if no other trouble isfound, the car should be immediately and care-
fully driven to a Hyundai dealer for inspection.
If further trouble is experienced, the vehicle
should not be driven at all but taken to a dealer
by a professional towing service or some other
safe method.
Your Hyundai is equipped with dual-diagonal
braking systems. This means you still have
braking on two wheels even if one of the dual
systems should fail. With only one of the dual
systems working, more than normal pedal travel
and greater pedal pressure are required to stop
the car. Also, the car will not stop in as short a
distance with only half of the brake system
working. If the brakes fail while you are driving,
shift to a lower gear for additional engine brak-
ing and stop the car as soon as it is safe to do
so.

Light
The charging system warning light should come
on when the ignition is turned on, then go out
when the engine is running. If the light stays on
while the engine is running, there is a malfunc-
tion in the electrical charging system. If the light
comes on while you are driving, stop, turn off
the engine and check under the hood. First,
make certain the generator drive belt is in
place. If it is, check the tension of the belt.
Do this as shown on page 6-13 by pushing
down on the center of the belt. And then, have
the system checked by your Hyundai dealer.

Low Fuel Level Warning Light
The low fuel level warning light comes on when
the fuel tank is approaching empty. When it
comes on, you should add fuel as soon as
possible. Driving with the fuel level warning
light on or with the fuel level below "E" can
cause the engine to misfire and damage the
catalytic converter.
B260L01Y-AATDoor Ajar Warning Light

The door ajar warning light warns you that a
door is not completely closed and the chime
warns you that driver's side front door is not
completely closed.
NOTE:To remind you not to lock the key inside the
car, the warning light comes on whenever
the key is in the "LOCK" position and a door
is open. The warning chime only sounds
whenever the key is in the "LOCK" position
and the driver's side front door is open. The
chime sounds and the light remains on until
the key is removed from the ignition.

TRIP A: first distance you have traveled from
your origination point to a first destination.
TRIP B: Second distance from the first destina-
tion to the final destination. The tachometer registers the speed of your
engine in revolutions per minute (rpm). It is
useful to help you shift at the appropriate en-
gine speed to avoid lugging or over-revving the

For dehumidified heating:
o Turn on the fan control switch.
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 "Fresh" mode

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.
B740D01A-AATOperation 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 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 operat-
ing condition.
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 "Recirculation" position on the air
intake control.B740B01S-AAT

AM reception
AM broadcasts can be received at greater
distances than FM broadcasts. This is be-
cause AM radio waves are transmitted at low
frequencies. These long, low frequency radio
waves can follow the curvature of the earth
rather than travelling straight out into the atmo-
sphere. In addition, they curve around obstruc-
tions so that they can provide better signal
coverage.FM broadcasts are transmitted at high fre-
quencies and do not bend to follow the earth's
surface. Because of this, FM broadcasts gen-
erally begin to fade at short distances from the
station. Also, FM signals are easily affected by
buildings, mountains, or other obstructions.
These can result in certain listening conditions
which might lead you to believe a problem
exists with your radio. The following conditions
are normal and do not indicate radio trouble:

FM reception
SSAR010A
AM and FM radio signals are broadcasted from
transmitter towers located around your city.
They are intercepted by the radio antenna on
your car. This signal is then received by the
radio and sent to your car speakers.
When a strong radio signal has reached your
vehicle, the precise engineering of your audio
system ensures high quality reproduction. How-
ever, in some cases the signal coming to your
vehicle may not be strong and clear. This can
be due to factors such as the distance from the
radio station, closeness of other strong radio
stations or the presence of buildings, bridges
or other large obstructions in the area.
