B990A02NF-AATOCCUPANT CLASSIFICATION SYSTEMYour vehicle is equipped with an occupant
classification system in the front passenger's
seat.
The Occupant Classification system is de-
signed to detect the presence of a properly-
seated front passenger and determine if the
passenger's front airbag should be enabled
(may inflate) or not. The driver's front airbag is
not affected or controlled by the Occupant
Classification system.
If the front passenger seat is occupied by a
person that the system determines to be of adult
size, and he/she sits properly (sitting upright
with the seatback in an upright position, cen-
tered on the seat cushion with their seat belt on,

!Always wash all exposed skin areas thor-
oughly with lukewarm water and a mild
soap after an accident in which the
airbags were deployed.
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. 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 If an airbag deploys, there may be a loud
noise followed by a fine dust released in
the vehicle. These conditions are nor-
mal and are not hazardous - the airbags
are packed in this fine powder. The dust
generated during airbag deployment
may cause skin or eye irritation as well as
aggravate asthma for some persons.
WARNING:

1FEATURES OF YOUR HYUNDAI44
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.
- Never place feet on the dashboard.

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 occupation classification sys-
tem, never install a child restraint system
in the front passenger's seat. A deploy-
ing airbag can forcefully strike a child
resulting in serious injuries or death.
Any child under 13 years of age should
ride in the rear seat. Children too large
for child restraints should use the avail-
able lap/shoulder belts. No matter what
type of crash, children of all ages are
safer when restrained 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.
WARNING:
Do not allow a passenger to ride in the front
seat when the “PASSENGER AIRBAG OFF”
indicator is illuminated, because the airbag
will not deploy in the event of a crash. If the
"PASSENGER AIR BAG OFF" indicator re-
mains illuminated after the passenger re-
positions themselves properly and the car
is restarted, Hyundai recommends that
passenger move to the rear seat because
the passenger's front airbag will not de-
ploy.
The “PASSENGER AIR BAG OFF” indicator
will not change according to the occupants
posture after the vehicle has been running
for 30 seconds. Front seat passengers
must stay properly seated to avoid serious
injury from a deploying airbag. For more
information see page 1-42.

1FEATURES OF YOUR HYUNDAI48
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 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:
B240C03NF-AATSRS CareThe SRS is virtually maintenance-free and so
there are no parts you can safely service by
yourself. If the SRS "AIRBAG" warning light
does not illuminate, or continuously remains on,
have your vehicle immediately inspected by
your Hyundai dealer.
Any work on the SRS system, such as remov-
ing, installing, repairing, or any work on the
steering wheel must be performed by a qualified
Hyundai technician. Improper handling of the
SRS system may result in serious personal
injury.
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
child 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.

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.

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 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.

B260L02HP-GAT
Door Ajar Warning Light and
Chime
The door ajar warning light warns you that a door
is not completely closed and the chime warns
you that the key is in the ignition switch.NOTE :The warning chime only sounds whenever
the key is in the ignition switch and the
driver's side front door is open simulta-
neously. The chime sounds until the key is
removed from the ignition switch or the
driver's side front door is closed.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.
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.
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.
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.
