Low Oil Pressure Warning
Light
CAUTION:
If the low oil pressure warning light stays
on while the engine is running, serious
engine damage may result. The oil pres-
sure warning light comes on whenever
there is insufficient oil pressure. In nor-
mal operation, it should come on when
the ignition switch is turned on, then go
out when the engine is started. If the oil
pressure warning light stays on while
the engine is running, there is a serious
malfunction.
If this happens, stop the car as soon as
it is safe to do so, turn off the engine and
check the oil level. If the oil level is low,
fill the engine oil to the proper level and
start the engine again. If the light stays
on with the engine running, turn the en-
gine off immediately. In any instance
where the oil light stays on when the
engine is running, the engine should be
checked by a Hyundai dealer before the
car is driven again.

The brake fluid level warning light indi-
cates that the brake fluid level in the brake
master cylinder is low and hydraulic brake
fluid conforming to DOT 3 or DOT 4 speci-
fications should be added. After adding
fluid, if no other trouble is found, the car
should be immediately and carefully 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.
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 braking and stop the car as soon as
it is safe to do so.
B260J01NF-AAT
Charging System Warning
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 malfunction in the
electrical charging system. If the light comes
on while you are driving, have the system
checked by your Hyundai dealer as soon
as possible.B260K01S-AAT
Trunk Lid Open Warning Light
This light remains on unless the trunk lid is
completely closed and latched.

Parking Brake/Low Brake Fluid
Level Warning Light
WARNING:
If you suspect brake trouble, have your
brakes checked by a Hyundai dealer as
soon as possible. Driving your car with
a problem in either the brake electrical
system or brake hydraulic system is
dangerous, and could result in a serious
injury or death.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 released.
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.

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.B260N02A-AAT
Check Engine - Malfunction
Indicator Light (MIL)
This light illuminates when there is a
malfunction of an exhaust gas related
component, and the system is not
functioning properly so that the exhaust
gas regulation values are not satisfied. This
light will also illuminate when the ignition key
is turned to the "ON" position, and will go out
in a few seconds after the engine is started.
If it illuminates while driving, or does not
illuminate when the ignition key is turned to
the "ON" position, take your car to your
nearest authorized Hyundai dealer and have
the system checked.

B260P02Y-GAT
ABS Service Reminder
Indicator (SRI) (If Installed)
When the key is turned to the "ON" position,
the Anti-Lock Brake System indicator will
come on and then go off in a few seconds.
If the ABS SRI remains on, comes on while
driving, or does not come on when the key
is turned to the "ON" position, this indicates
that there may be a problem with the ABS.
If this occurs, have your vehicle checked
by your Hyundai dealer as soon as
possible. The normal braking system will
still be operational, but without the
assistance of the anti-lock brake system.
WARNING:
If both the ABS SRI and Parking Brake/
Brake fluid level warning lights remain
"ON" or come on while driving, there
may be a problem with E.B.D. (Electronic
Brake Force Distribution).
If this occurs, avoid sudden stops and
have your vehicle checked by your
Hyundai dealer as soon as possible.

WARNING:
- When using a portable fuel container,
be sure to place the container on the
ground while refueling. Static elec-
tricity discharge from the container
can ignite fuel vapors causing a fire.
While starting refueling, contact
should be maintained until the filling
is complete.
- Do not use cellular phones around a
gas station. The electric current or
electronic interference from cellular
phones can ignite fuel vapors caus-
ing a fire.
- When refueling, always turn the en-
gine off. Sparks by engine compart-
ment electrical equipment can ignite
fuel vapors causing a fire. After re-
fueling, check to make sure the fuel
filler cap is securely closed, and
then start the engine.
- Do not smoke or try to light cigarettes
around a gas station. Automotive
fuels are flammable.
o After refueling, make sure the fuel
cap is installed securely to prevent
fuel spillage in the event of an acci-
dent
o Tighten the cap until it clicks, otherwise
the "
" check engine light will illu-
minate
o If you open the fuel filler cap during
high ambient temperatures, a slight
"pressure sound" may be heard. This
is normal and not a cause for concern.
Whenever you open the fuel filler cap,
turn it slowly.
o Do not "top off" after the nozzle auto-
matically shuts off when refueling.
o Automotive fuels are flammable/ex-
plosive materials. When refueling,
please note the following guidelines
carefully.
- Before touching the fuel nozzle or
fuel filler cap, have one's hands in
contact with metal parts away from
the filler neck to discharge static
electricity.
- Do not get back in the vehicle while
refueling. Do not operate anything
that can produce static electricity.
Static electricity discharge can ignite
fuel vapors resulting in an explo-
sion.

WARNING: ENGINE EXHAUST CAN BE DANGEROUS!
C010A03A-AATEngine exhaust fumes can be extremely dangerous. If, at any time, you smell exhaust fumes inside the vehicle, open the
windows immediately.
o Do not inhale exhaust fumes.
Exhaust fumes contain carbon monoxide, a colorless, odorless gas that can cause unconsciousness and death by
asphyxiation.
o Be sure the exhaust system does not leak.
The exhaust system should be checked whenever the vehicle is raised to change the oil or for any other purpose. If you
hear a change in the sound of the exhaust or if you drive over something that strikes the underneath side of the car, have
the exhaust system checked as soon as possible by your Hyundai dealer.
o Do not run the engine in an enclosed area.
Letting the engine idle in your garage, even with the garage door open, is a hazardous practice. Never run the engine
in your garage any longer than it takes to start the engine and back the car out.
o Avoid idling the engine for prolonged periods with people inside the car.
If it is necessary to idle the engine for a prolonged period with people inside the car, be sure to do so only in an open area
with the air intake set at "Fresh" and fan operating at one of the higher speeds so fresh air is drawn into the interior.
If you must drive with the trunk lid open because you are carrying objects that make this necessary:
1. Close all windows.
2. Open side vents.
3. Set the air intake control at "Fresh", the air flow control at "Floor" or "Face" and the fan at one of the higher speeds.
To assure proper operation of the ventilation system, be sure the ventilation air intakes located just in front of the windshield
are kept clear of snow, ice, leaves or other obstructions.
