2004 Hyundai Sonata Owner's Manual

FEATURES OF YOUR HYUNDAI 1- 29
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 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 or killed
by an airbag deployment in case of an
accident.
Do not allow children to ride in the front
passenger seat. If older children (teen-
agers and older) must ride in the front
seat, make sure they are always properly
belted and that the seat is moved back as
far as possible.
o For maximum safety protection in all
types of crashes, all occupants includ-
ing the driver should always wear their
seat belts whether or not an airbag is
also provided at their seating position to
minimize the risk of severe injury or
death in the event of a crash. Do not sit
or lean unnecessarily close to the airbag
while the vehicle is in motion.
o The SRS airbag system must deploy very
rapidly to provide protection in a crash.
If an occupant is out of position because
of not wearing a seat belt, the airbag may
forcefully contact the occupant causing
serious or fatal injuries.B240B02A-AATSRS Components and Functions
The SRS service reminder indicator (SRI) on
the instrument panel will blink for about 6 sec-
onds after the ignition key is turned to the "ON"
position or after the engine is started, after which
the SRI should go out. The SRS consists of the following components:
- Driver's Airbag Module
- Passenger's Airbag Module
- Knee Bolster
- SRS Service Reminder Indicator (SRI)
- SRS Control Module (SRSCM)
The SRSCM continually monitors all elements
while the ignition is "ON" to determine if a frontal
or near-frontal impact is severe enough to
require airbag deployment.B240B01L

!
The airbag modules are located both in the
center of the steering wheel and in the front
passenger's panel above the glove box.
When the SRSCM detects a considerable im-
pact to the front of the vehicle, it will automatically
deploy the airbags.
Upon deployment, tear seams molded directly
into the pad covers will separate under pres-
sure from the expansion of the airbags. Further
opening of the covers then allows full inflation of
the airbags.
A fully inflated airbag in combination with a
properly worn seat belt slows the driver's or the
passenger's forward motion, thus reducing the
risk of head or chest injury.
After complete inflation, the airbag immediately
starts deflating, enabling the driver to maintain
forward visibility.
CAUTION:When installing the container of liquid air
freshener inside a vehicle, do not place it
near the instrument cluster nor on the in-
strument panel pad surface. If there is any
leakage from the air freshener onto these
areas (Instrument cluster, instrument panel
pad 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 gener-
ated during airbag deployment may
cause skin irritation. Be sure to wash
your hands and face thoroughly with
lukewarm water and a mild soap after an
accident in which the airbags were de-
ployed.
o The SRS can function only when the
ignition key is in the "ON" position. If the
SRS SRI does not come on, or continu-
ously remains on, after flashing for about
6 seconds when the ignition key is
turned to the "ON" position, or after the
engine is started, or comes on while
driving, the SRS is not working properly.
If this occurs, have your vehicle immedi-
ately inspected by your Hyundai dealer.
o Before you replace a fuse or disconnect
a battery terminal, turn the ignition key
to the "LOCK" position or remove the
ignition key. Never remove or replace the
air bag related fuse(s) when the ignition
key is in the "ON" position. Failure to
heed this warning will cause the SRS SRI
to illuminate.

B990A04Y-AATPASSENGER PRESENCE DETECTION
The passenger presence detection system
detects the presence of a passenger in the right
front seat. If no passenger is recognized on the
front passenger seat, the deployment of the
front passenger and/or side airbag and seat belt
pretensioner will be prevented.
This system is designed to prevent the replace-
ment of airbag components that deploy need-
lessly in an accident.
NOTE:Luggage or other cargo heavier than 33 lbs
(15 kg) should not be placed on the passen-
ger front seat. This can allow the deploy-
ment of the front passenger and/or side air
bag in the case of an accident.
WARNING:The Passenger Presence Detection system
is not intended to prevent airbag deploy-
ment while a child is in the front passen-
ger's seat. It is intended only as a means to
reduce unnecessary collision damage re-
pair expense by preventing airbag and seat
belt pretensioner deployment when the
right front passenger seat is unoccupied.
Deployment is still possible if only a few
pounds are placed upon the seat. There-
fore, children must not be transported inthe front seat. All children must be seated
in the rear seat and properly restrained with
the vehicle's restraint system or a child
restraint system appropriate for the child's
size and weight.
B990B03Y-AATSide Impact Airbag (If installed)
Your Hyundai is equipped with a side impact
airbag in each front seat. The purpose of the
airbag is to provide the vehicle's driver and/or
the front passenger with additional protection
than that offered by the seat belt alone. The side
impact airbags are designed to deploy only
during certain side-impact collisions, depend-
ing on the crash severity, angle, speed and point
of impact. The side impact air bags are not
designed to deploy in all side impact situations.
WARNING:o For best protection from the side impact
airbag system and to avoid being injured
by the deploying side impact airbag,
both front seat occupants should sit in
an upright position with the seat belt
properly fastened. The driver's hands
should be placed on the steering wheel
at the 9:00 and 3:00 o'clock positions.
The passenger's arms and hands should
be placed in their laps.
o Do not use any accessory seat covers.
o Use of seat covers could reduce or pre-
vent the effectiveness of the system.
o Do not install any accessories on the
side or near the side impact airbag.
o Do not use excessive force on the side of
the seat.

B240C01A-AATSRS Care
o The SRS is virtually maintenance free and
there are no parts you can safely service by
yourself. The entire SRS system must be
inspected by an authorized Hyundai dealer
10 years after the date that the vehicle was
manufactured.
o 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 airbag 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
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 place any objects over the airbag
or between the airbag and yourself.
o Do not place any objects (an umbrella,
bag, etc.) between the front door and the
front seat. Such objects may become
dangerous projectiles and cause injury
if the supplemental side impact air bag
inflates.
o To prevent unexpected deployment of
the side impact air bag that may result in
personal injury,avoid impact to the side
airbag sensor when the ignition key is
on.

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, be sure to inform
the new owner of these important points
and 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.

B260H02A-AATParking Brake/Brake Fluid Level
Warning Lightadding 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 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.
The brake 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
B260J01A-AATCharging 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 6-18 by pushing down on the center of
the belt. And then have the system checked by
your Hyundai dealer.
B260K01S-AATTrunk Lid Open Warning Light

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 driver's side front door is not completely
closed.
NOTE:To remind you not to lock the key inside the
car, the warning light comes on whenever
the key is in the "LOCK" position and a door
is open. The warning chime only sounds
whenever the key is in the "LOCK" position
and driver's side front door is open. The
