!CAUTION:If the Occupant Classification® system is
not working properly, the SRS airbag warn-
ing light on the instrument panel will
illuminate because the SRS airbag is con-
nected with the Occupant Classification
®
system. If there is a malfunction of the
Occupant Classification® system, the "Pas-
senger Airbag Off" indicator will not illumi-
nate and the front passenger's airbag will
deploy in frontal crashes even if there is no
occupant in the front passenger's seat. If
the SRS airbag warning light does not illu-
minate when the ignition key is turned to
"ON" position, if it remains illuminated after
blinking for approximately 6 seconds, or if
it illuminates while the vehicle is being
driven, have an authorized Hyundai dealer
inspect the Occupant Classification sys-
tem with SRS airbag system as soon as
possible.
B990A01E-GAT
OCCUPANT CLASSIFICATION®
SYSTEM
The Occupant Classification® system detects
the presence of a passenger in the front
passenger's seat and will turn off the front
passenger's airbag under certain conditions.
The driver's airbag and the driver's side impact
airbag are not connected with the Occupant
Classification
® system.
The Occupant Classification® system is de-
signed to detect the presence of a properly-
seated occupant and determine if the
passenger's airbag and the passenger's side
impact airbag should be enabled (may inflate) or
not.
HXDFL240-A
If the front passenger seat is unoccupied or
occupied by someone lighter than 56.4 pounds
(25.6 kg), the indicator "PASSENGER AIR BAG
OFF" will be displayed, and the front passenger's
airbag will be turned off and will not deploy in
frontal crashes.
NOTE:o The "Passenger Airbag Off" indicator
illuminates for about 6 seconds after the
ignition key is turned to the "ON" posi-
tion or after the engine is started, and
then turns off in a few seconds.
o If the "Passenger Airbag Off" indicator
illuminates, the passenger's airbag will
not deploy in frontal crashes. If the "Pas-
senger Airbag Off" indicator does not
illuminate, the passenger's airbag will
deploy in frontal crashes.
o If your vehicle is equipped with side
impact airbags, the front passenger's
side impact airbag will not deploy when
the telltale indicator is illuminated.

WARNING:o Do not install a child restraint system in
the front passenger seat position.
A child restraint system must never be
placed in the front seat. The infant or
baby could be severely injured by an
airbag deployment in case of an acci-
dent.
o Modification to SRS components or wir-
ing, including the addition of any kind of
badges to the pad covers or modifica-
tions to the body structure, can ad-
versely affect SRS performance and lead
to possible injury.
o For cleaning the airbag pad covers, use
only a soft, dry cloth or one which has
been moistened with plain water. Sol-
vents or cleaners could adversely affect
the airbag covers and proper deploy-
ment of the system.
o No objects should be placed over or near
the airbag modules on the steering
wheel, instrument panel, and the front
passenger's panel above the glove box,
because any such object could cause
harm if the vehicle is in a crash severe
enough to cause the airbags to inflate.
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 firing 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 the floor, you
shouldn't try to start the engine; have
the car towed to an authorized Hyundai
dealer.

B260B01A-AAT
SRS (Airbag) Service
Reminder Indicator (SRI)
The SRS service reminder indicator (SRI) comes
on and flashes for about 6 seconds after the
ignition 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 SRI does not come on,
or continuously remains on after flashing 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.
B260P01E-GAT
ABS Service Reminder
Indicator (SRI) (If installed)
When the key is turned to the "ON" position, the
Anti-Lock Brake System will come on and then
go off after three 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.
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.
B260F01A-AAT
High Beam Indicator Light
The high beam indicator light comes on when-
ever the headlights are switched to high beam
of flash position.
WARNING:If the both 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.

Low Oil Pressure Warning Light
B260H03A-AAT
Parking Brake/Low Brake Fluid
Level Level Warning Light
CAUTION:
If the oil pressure warning light stays on
while the engine is running, serious engine
damage may result. The oil pressure warn-
ing light comes on whenever there is insuf-
ficient 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
may be 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 engine off imme-
diately. 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.
!
Warning Light Operation
The 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 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.

2. Pull the secondary catch lever up and lift the
hood.
3. Hold the hood open with the support rod.
Before closing the hood, return the support rod
to its clip to prevent it from rattling. Lower the
hood until it is about 1 ft. (30 cm) above the
closed position and let it drop. Make sure that it
locks into place.
WARNING:o Always double check to be sure that the
hood is firmly latched before driving
away. If it is not latched, the hood could
fly open while the vehicle is being driven,
causing a total loss of visibility, which
might result in an accident.
o The support rod must be inserted com-
pletely into the hole provided in the
hood whenever you inspect the engine
compartment. This will prevent the hood
from falling and possibly injuring you.
o Do not move the vehicle with the hood
in the raised position, as vision is ob-
structed and the hood could fall or be
damaged.
!CAUTION:Make sure that the support rod has been
released prior to closing the hood.
