B990A02NF-AATOCCUPANT CLASSIFICATION SYS-
TEMYour vehicle is equipped with an occupant
classification system in the front
passenger's seat.
The occupant classification system is
designed to detect the presence of a
properly-seated front passenger and
determine if the passenger's front air bag
should be enabled (may inflate) or not. The
driver's front air bag 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

!Always wash all exposed skin areas
thoroughly 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 inspected by
your Hyundai dealer.
o Before you replace a fuse or discon-
nect a battery terminal, turn the igni-
tion 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. parts. If the liquid from the air fresh-
ener 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 normal 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 HYUNDAI42
When an adult is seated in the front
passenger seat, if the "PASSENGER AIR
BAG OFF" indicator 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. This will
allow the system to detect the person and to
enable the passenger air bag.
o Never excessively recline the front
passenger seatback.

NOTE:The "PASSENGER AIR BAG OFF"
indicator illuminates for about 4 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 after several more seconds.
!
WARNING:
If the occupant classification system is
not working properly, the SRS air bag
warning light on the instrument panel will
illuminate because the passenger's front
air bag is connected with the occupant
classification system. If there is a mal-
function of the occupant classification
system, the "PASSENGER AIR BAG
OFF" indicator will not illuminate and the
passenger's front air bag will inflate in
frontal impact crashes even if there is no
occupant in the front passenger's seat.
If the SRS air bag warning light does not
illuminate when the ignition key is turned
to the "ON" position, remains illumi-
nated 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 au-
thorized Hyundai dealer inspect the oc-
cupant classification system and the
SRS air bag system as soon as possible. If the "PASSENGER AIR BAG OFF" indica-
tor is still on, ask the passenger to move to
the rear seat.
WARNING:
Do not allow an adult 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 remains
illuminated after the passenger reposi-
tions themselves properly and the car is
restarted, Hyundai recommends that
passenger move to the rear seat
because the passenger's front airbag
will not deploy.
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.
WARNING:
Do not put a heavy load in the front
passenger seatback pocket or on the
front passenger seat. Do not hang onto
the front passenger seat. Do not hang
any items such as seatback table on the
front passenger seatback. Do not place
feet on the front passenger seatback.
Do not place any items under the front
passenger seat. Any of these could
interfere with proper sensor operation.

o If the airbags inflate, they must be
replaced 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 precau-
tions and can give you the necessary
information. Failure to follow these
precautions and procedures could in-
crease 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 re-
mains on, have your vehicle immediately
inspected by your Hyundai dealer.
Any work on the SRS system, such as
removing, 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
accident.
o Modification to SRS components or
wiring, including the addition of any
kind of badges to the pad covers or
modifications to the body structure,
can adversely affect SRS perfor-
mance 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.
Solvents or cleaners could adversely
affect the airbag covers and proper
deployment 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 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. 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 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.
