o The SRS can function only when the
ignition key is in the "ON" position. If the
SRS "AIRBAG" warning light does not
illuminate, or continuously remains on
after illuminating for about 6 seconds
when the ignition key is turned to the
"ON" position, or after the engine is
started, comes on while driving, the SRS
is not working properly. If this occurs,
have your vehicle immediately inspect-
ed by your Hyundai dealer.
o Before you replace a fuse or disconnect
a battery terminal, turn the ignition key
to the "LOCK" position and remove the
ignition key. Never remove or replace the
airbag related fuse(s) when the ignition
key is in the "ON" position. Failure to
heed this warning will cause the SRS
"AIRBAG" warning light to illuminate. Passenger's Front Airbag
CAUTION:
o Do not install or place any accessories
(drink holder, cassette holder, sticker,
etc.) on the front passenger's panel
above the glove box in a vehicle with a
passenger's airbag. Such objects may
become dangerous projectiles and cause
injury if the passenger's airbag inflates.
o When installing a container of liquid air
freshener inside the vehicle, do not place
it near the instrument cluster nor on the
instrument panel surface. If there is any
leakage from the air freshener onto these
areas (instrument cluster, instrument
!
B240B04NF
panel or air ventilator), it may damage
these parts. If the liquid from the air
freshener does leak onto these areas,
wash them with water immediately.
WARNING:
o When the SRS is activated, there may be
a loud noise and fine dust will be re-
leased throughout the vehicle. These
conditions are normal and are not haz-
ardous. However, the fine dust generat-
ed during airbag deployment may cause
skin irritation. Wash all exposed skin
areas thoroughly with lukewarm water
and a mild soap after an accident in
which the airbags were deployed.
WARNING:
NOTE:
Your vehicle's Supplemental Restraint Sys-
tem Control Module is equipped a record-
ing device which may record the use of the
seat belt restraint system by the driver and
front passenger in certain collisions.

!
NOTE:The "PASSENGER AIR BAG OFF" indicator
illuminates for about 6 seconds after the
ignition key is turned to the "ON" position
or after the engine is started. If the front
passenger seat is occupied, the occupant
classification sensor will then classify the
front passenger within approximately 10
seconds after the ignition is turned on.
CAUTION:
If the occupant classification system is not
working properly, the SRS airbag warning
light on the instrument panel will
illuminate because the passenger's front
airbags are connected with the occupant
classification system. If there is a malfunc-
tion of the occupant classification system,
the "PASSENGER AIR BAG OFF" indicator
will not illuminate and the passenger's front
airbags will inflate in frontal impact crashes
even if there is no occupant in the front
passenger's seat. If the SRS airbag warning
light does not illuminate when the ignition
key is turned to the "ON" position, remains
illuminated after approximately 6 seconds
when the ignition key is turned to the "ON"
position, or if it illuminates while the vehicle
is being driven, have an authorized Hyundai
dealer inspect the occupant classification
system and the SRS airbag system as soon
as possible.
!
WARNING:
o Even though your vehicle is equipped
with the occupant classification sys-
tem, do not install a child restraint sys-
tem in the front passenger's seat. A child
restraint system must never be placed in
the front seat. Children who are too large
for child restraint systems should al-
ways occupy the rear seat and use the
available lap/shoulder belts. Children are
afforded the most safety in the event of
an accident when they are restrained by
a proper restraint system in the rear seat.
o If the "PASSENGER AIR BAG OFF" indi-
cator is illuminated when the front
passenger's seat is occupied by an adult
and he/she sits properly (sitting upright
with the seatback in an upright position,
centered on the seat cushion with their
seat belt on, legs comfortably extended
and their feet on the floor), have that
person sit in the rear seat.
o If you change the weight on the front
passenger seat just after sit-in or restart
of the engine, the "PASSENGER AIR
BAG OFF" indicator may be turned on or
off for a few seconds, disabling or en-
abling the passenger airbags. After the
initial stage of about 30 seconds, the
"PASSENGER AIR BAG OFF" indicator
will not toggle.
When an adult is seated in the front passenger
seat, if the "PASSENGER AIR BAG OFF" indica-
tor is on, turn the ignition key to "LOCK" and ask
the passenger to sit properly (sitting upright with
the seat back in an upright position, centered on
the seat cushion with their seat belt on, legs
comfortably extended and their feet on the
floor). Restart the engine and have the person
remain in that position for about 30 seconds. This
will allow the system to detect the person and to
enable the passenger airbag. If the "PASSEN-
GER AIR BAG OFF" indicator is still on, turn the
ignition key to "LOCK" and ask the passenger to
sit properly and restart the engine again.
If the "PASSENGER AIR BAG OFF" indicator is
still on, ask the passenger to move to the rear
seat. After the vehicle starts, the "PASSENGER
AIR BAG OFF" indicator will not change accord-
ing to the passenger's posture.Normal position

B240D01NF-AATAdditional Safety PrecautionsoNever let passengers ride in the cargo
area (trunk) or on top of a folded-down
back seat. All occupants should sit upright,
fully back in their seats with their seat belts
on and their feet on the floor.
oPassengers should not move out of or
change seats while the vehicle is mov-
ing. A passenger who is not wearing a seat
belt during a crash or emergency stop can
be thrown against the inside of the vehicle,
against other occupants, or out of the ve-
hicle.
oEach seat belt is designed to restrain one
occupant. If more than one person uses the
same seat belt, they could be seriously
injured or killed in a collision.
oDo not use any accessories on seat
belts. Devices claiming to improve occu-
pant comfort or reposition the seat belt can
reduce the protection provided by the seat
belt and increase the chance of serious
injury in a crash.oPassengers should not place hard or
sharp objects between themselves and
the airbags. Carrying hard or sharp objects
on your lap or in your mouth can result in
injuries if an airbag inflates.
oKeep occupants away from the airbag
covers. All occupants should sit upright, fully
back in their seats with their seat belts on and
their feet on the floor. If occupants are too
close to the airbag covers, they could be
injured if the airbags inflate.
oDo not attach or place objects on or near
the airbag covers. Any object attached to
or placed on the front or side impact airbag
covers could interfere with the proper opera-
tion of the airbags.
oDo not modify the front seats. Modifica-
tion of the front seats could interfere with the
operation of the supplemental restraint sys-
tem sensing components or side impact
airbags.
oDo not place items under the front seats.
Placing items under the front seats could
interfere with the operation of the supple-
mental restraint system sensing compo-
nents and wiring harnesses.
o If the airbags inflate, they must be re-
placed by an authorized Hyundai dealer.
o Do not tamper with or disconnect SRS
wiring, or other components of the SRS
system. Doing so could result in injury,
due to accidental inflation of the airbags
or by rendering the SRS inoperative.
o If components of the airbag system must
be discarded, or if the vehicle must be
scrapped, certain safety precautions
must be observed. Your Hyundai dealer
knows these precautions and can give
you the necessary information. Failure
to follow these precautions and proce-
dures could increase the risk of personal
injury.
o If you sell your vehicle, make certain that
this manual is transferred to the new
owner.
o If your car was flooded and has soaked
carpeting or water on flooring, you
shouldn't try to start the engine; have
the car towed to an authorized Hyundai
dealer.

WARNING AND INDICATOR LIGHTSB260B01JM-AAT
SRS (Airbag) Warning Light
The SRS warning light comes on for about 6
seconds after the key is turned to the "ON"
position or after the engine is started, after which
it will go out.
This light also comes on when the SRS is not
working properly. If the AIRBAG warning light
does not come on, or continuously remains on
after operating for about 6 seconds when you
turned the ignition key to the "ON" position or
started the engine, or if it comes on while driving,
have the SRS inspected by an authorized
Hyundai dealer.B260D01A-AAT
Turn Signal Indicator Lights
The blinking green arrows on the instrument
panel show the direction indicated by the turn
signals. If the arrow comes on but does not blink,
blinks more rapidly than normal, or does not
illuminate at all, a malfunction in the turn signal
system is indicated. Your dealer should be
consulted for repairs.
B260E01NF-AAT
Seat Belt Reminder Light
and Chime (Driver's side)
The driver's seat belt reminder light blinks and
the warning chime sounds for 6 seconds when
the ignition key is turned from the "OFF" position
to the "ON" or "START" position to remind the
driver to fasten the driver's seat belt.B260F01A-AAT
High Beam Indicator Light
The high beam indicator light comes on when-
ever the headlights are switched to the high
beam or flash position.
B260G01A-AAT
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 pressure warning
light comes on whenever there is insufficient
oil pressure. In normal 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 malfunc-
tion.
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 engine 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.

B260H02A-AAT
Parking Brake/Low Brake Fluid
Level Warning Light
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 is
found, 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 braking
and stop the car as soon as it is safe to do so.
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 sys-
tem or brake hydraulic system is danger-
ous, 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 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.
B260J02A-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 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 6-19 by pushing down on the center of
the belt. 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.

B260M01A-AAT
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.
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.
B260N02A-AAT
Check Engine - Malfunction In-
dicator 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.
B265C01NF-AAT
Electronic Stability Control
(ESC) Indicator Lights
(If Installed)
The electronic stability control indicators change
operation according to the ignition switch posi-
tion and whether the system is in operation or
not.
They will illuminate when the ignition key is
turned to the "ON" position, but should go out
after three seconds. If the ESC or ESC-OFF
indicator stays on, take your car to your autho-
rized Hyundai dealer and have the system
checked. See section 2 for more information
about the ESC.
