2003 Hyundai Sonata wiring

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

FEATURES OF YOUR HYUNDAI 1- 33
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.

C160G01A-AATTo Keep Locks from Freezing
To keep the locks from freezing, squirt an
approved de-icer fluid or glycerine into the key
opening. If a lock is covered with ice, squirt it with
an approved de-icing fluid to remove the ice. If
the lock is frozen internally, you may be able to
thaw it out by using a heated key. Handle the
heated key with care to avoid burning the
fingers.
C160D01A-AAT
Check Battery and Cables
Winter puts additional burdens on the battery
system. Visually inspect the battery and cables
as described in Section 6. The level of charge
in your battery can be checked by your Hyundai
dealer or a service station.
C160F01A-AATCheck Spark Plugs and Ignition
System
Inspect your spark plugs as described in Sec-
tion 6 and replace them if necessary. Also
check all ignition wiring and components to be
sure they are not cracked, worn or damaged in
any way.
C160E01A-AATChange to "Winter Weight" Oil if
Necessary
In some climates it is recommended that a lower
viscosity "winter weight" oil be used during cold
weather. See Section 9 for recommendations.
If you aren't sure what weight oil you should use,
consult your Hyundai dealer.
C160C01A-AATUse High Quality Ethylene Glycol
Coolant
Your Hyundai is delivered with high quality
ethylene glycol coolant in the cooling system. It
is the only type of coolant that should be used
because it helps prevent corrosion in the cool-
ing system, lubricates the water pump and
prevents freezing. Be sure to replace or replen-
ish your coolant in accordance with the main-
tenance schedule in Section 5. Before winter,
have your coolant tested to assure that its
freezing point is sufficient for the temperatures
anticipated during the winter.
C160B01A-AATSnowy or Icy Conditions
To drive your vehicle in deep snow, it may be
necessary to use snow tires or to install tire
chains on your tires. If snow tires are needed,
it is necessary to select tires equivalent in size
and type of the original equipment tires. Failure
to do so may adversely affect the safety and
handling of your car. Furthermore, speeding,
rapid acceleration, sudden brake applications,
and sharp turns are potentially very hazardous
practices.
During deceleration, use engine braking to the
fullest extent. Sudden brake applications on
snowy or icy roads may cause skids to occur.
You need to keep sufficient distance between
the vehicle in operation in front and your vehicle.
Also, apply the brake gently. It should be noted
that installing tire chains on the tire will provide
a greater driving force, but will not prevent side
skids.
NOTE:Tire chains are not legal in all states. Check
state laws before fitting tire chains.

CORROSION PREVENTION AND APPEARANCE CARE 4- 5
Take a piece of cheese cloth and using any mild
soap and lukewarm water, work up a good
lather. Thoroughly wash the leather. Wipe clean
with a slightly damp cloth and dry with soft cloth.
Do this as often as the leather becomes
soiled.
During tanning operations, sufficient oils are
incorporated through processing that none need
be applied during the life of the leather. Oil
applied to the finished surface will in no way help
the leather and may do more harm than good.
Varnishes and furniture polishes should never
be used under any conditions.E040D01A-AATCleaning the Seat Belts
To clean the seat belts, use a cloth or sponge
with mild soap or detergent and warm water. Do
not use strong detergents, dye, bleach or abra-
sive materials on the seat belts as this may
weaken the fabric.
While cleaning the belts, inspect them for ex-
cessive wear, cuts, fraying or other signs of
damage and replace them if necessary.
E040C01A-AATCleaning the Carpets
Use a foam-type carpet cleaner. Cleaners of
this type are available in aerosol cans in liquid
form or powder. Read the instructions and
follow them exactly. Using a vacuum cleaner
with the appropriate attachment, remove as
much dirt from the carpets as possible. Apply
the foam following the manufacturer's direc-
tions, then rub in overlapping circles. Do not add
water. These cleaners work best when the
carpet is kept as dry as possible.
E050A01A-AATAny Questions?
If you have any questions about the care of your
car, consult your Hyundai dealer.
E040E01A-AATCleaning the Windows
You may use any household window cleaner on
the windows. However, when cleaning the in-
side of the rear window be careful not to damage
the rear window defroster wiring.

G190A01A-AATCHECKING DRIVE BELTS
Drive belts should be checked periodically for
proper tension and adjusted if necessary. At the
same time, belts should be examined for cracks,
wear, fraying or other evidence of deterioration
and replaced if necessary.
Belt routing should also be checked to be sure
there is no interference between the belts and
other parts of the engine. After a belt is replaced,
the new belt should be adjusted again after two
or three weeks to eliminate slack resulting from
initial stretching after use.A fusible link will melt if the electrical circuits from
the battery are ever overloaded, thus prevent-
ing damage to the entire wiring harness. (This
could be caused by a short in the system
drawing too much current.) If this ever happens,
have a Hyundai dealer determine the cause,
repair the system and replace the fusible link.
The fusible links are located in a under hood
junction box for easy inspection.
!
The instrument panel junction box for the lights
and other electrical accessories will be found
low on the dashboard on the driver’s side. Inside
the box you will find a list showing the circuits
protected by each fuse.
CAUTION:When replacing a fusible link, never use
anything but a new fusible link with the
same or lower amperage rating. Never use
a piece of wire or a higher-rated fusible link.
This could result in serious damage and
create a fire hazard.
