Replacing a Fusible Link
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 re-
placed, 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 pre-
venting 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 relay box for
easy inspection.
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.

The fluid in the battery contains a strong solu-
tion of sulfuric acid, which is poisonous and
highly corrosive. Be careful not to spill it on
yourself or the car. If you do spill battery fluid on
yourself, immediately do the following:
o If battery fluid is on your skin, flush the
affected areas with water for at least 15
minutes and then seek medical assistance.
o If battery fluid is in your eyes, rinse out your
eyes with water and get medical assistance
as soon as possible. While you are being
driven to get medical assistance, continue
to rinse your eyes by using a sponge or soft
cloth saturated with water.
o If you swallow battery fluid, drink a large
quantity of water or milk followed by milk of
magnesia, eat a raw egg or drink vegetable
oil. Get medical assistance as soon as
possible.
While batteries are being charged (either by a
battery charger or by the vehicle’s generator),
they produce explosive gases. Always observe
these warnings to prevent injuries from occur-
