Drive belts should be checked periodically for
proper tension. At the same time, belts should
be examined for cracks, wear, fraying or other
evidence of deterioration and replaced if neces-
sary.
When a new belt is replaced, the belt should be
located within the pulley of flat idler.
Belt routing should also be checked to be sure
there is no interference between the belts and
other parts of the engine.
NOTE:Drive belt tension is adjusted automatically
by the auto tensioner.
CHECKING AND REPLACING
FUSESG200A01A-AATReplacing a Fusible LinkA 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 relay box in the
engine compartment for easy inspection.
HNF4004
!
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.

2. Open the fuse box and examine each fuse.
Remove each fuse by pulling it toward you
(a small "fuse puller" tool is contained in the
relay and fuse box of the engine room to
simplify this operation).
3. Be sure to check all other fuses, even if you
G200B02NF
find one that appears to have burned out.
4. Replace the blown fuse by pressing a new
fuse of the same rating into place. The fuse
should be a snug fit. If it is not, have the fuse
clip repaired or replaced by a Hyundai dealer.
If you do not have a spare fuse, you may be
able to borrow a fuse of the same or lower
rating from an accessory you can tempo-
rarily get along without (the radio or cigarette
lighter, for example). Always remember to
replace the borrowed fuse.

GoodBurned outCAUTION:
A burned-out fuse indicates that there is a
problem in the electrical circuit. If you re-
place a fuse and it blows as soon as the
accessory is turned on, the problem is
serious and should be referred to a Hyundai
dealer for diagnosis and repair. Never re-
place a fuse with anything except a fuse
with the same or a lower amperage rating.
A higher capacity fuse could cause damage
and create a fire hazard.NOTE:See page 6-36 for the fuse panel descrip-
tions.
G200B01NF-AATReplacing Accessory Fuse
G200B01NF-A
The fuse box for the lights and other electrical
accessories will be found on the left side of the
instrument panel. Inside the box you will find a
list showing the circuits protected by each fuse.
If any of your car's lights or other electrical
accessories stop working, a blown fuse could
be the reason. If the fuse has burned out, you
will see that the metal strip inside the fuse has
burned through. If you suspect a blown fuse,
follow this procedure:
1. Turn off the ignition and all other switches.
