FUSES
A vehicle’s electrical system is protected
from electrical overload damage by
fuses. This vehicle has 2 fuse panels, one locat-
ed in the driver’s side panel bolster, the
other in the engine compartment.
If any of your vehicle’s lights, acces-
sories, or controls do not work, check the
appropriate circuit fuse. If a fuse has
blown, the element inside the fuse will be
melted.
If the electrical system does not work,
first check the driver’s side fuse panel.
Always replace a blown fuse with one of
the same rating.
If the replacement fuse blows, this indi-
cates an electrical problem. Avoid using
the system involved and immediately
consult an authorized HYUNDAI dealer.
Three kinds of fuses are used: blade type
for lower amperage rating, cartridge type,and multi fuse for higher amperage rat- ings.

WARNING - Fuse replace-
ment
Never replace a fuse with any-
thing but another fuse of the
same rating.
A higher capacity fuse could cause damage and possibly a
fire.
Never install a wire or aluminum foil instead of the proper fuse -
even as a temporary repair. It may
cause extensive wiring damage
and a possible fire.
CAUTION
Do not use a screwdriver or anyother metal object to remove fuses because it may cause a short circuitand damage the system.

If a bulb becomes damaged orcracked, replace it immediately
and carefully dispose of it.
Wear eye protection when chang- ing a bulb. Allow the bulb to cool
down before handling it.

WARNING- Halogen bulbs
Halogen bulbs contain pressur-ized gas that will produce flying
pieces of glass if broken.
Always handle them carefully, and avoid scratches and abra-
sions. If the bulbs are lit, avoid
contact with liquids. Never touch
the glass with bare hands.
Residual oil may cause the bulb
to overheat and burst when lit. A
bulb should be operated only
when installed in a headlight.

Waxing
Wax the vehicle when water will no
longer bead on the paint.
Always wash and dry the vehicle before
waxing. Use a good quality liquid or
paste wax, and follow the manufacturer’s
instructions. Wax all metal trim to protect
it and to maintain its luster.
Removing oil, tar, and similar materials
with a spot remover will usually strip the
wax from the finish. Be sure to re-wax
these areas even if the rest of the vehicle
does not yet need waxing.Finish damage repair
Deep scratches or stone chips in the
painted surface must be repaired
promptly. Exposed metal will quickly rust
and may develop into a major repair
expense.
✽ ✽
NOTICE
If your vehicle is damaged and requires
any metal repair or replacement, be sure
the body shop applies anti-corrosion
materials to the parts repaired or
replaced.
Bright-metal maintenance
To remove road tar and insects, use a
tar remover, not a scraper or other
sharp object.
To protect the surfaces of bright-metal parts from corrosion, apply a coating of
wax or chrome preservative and rub to
a high luster.
During winter weather or in coastal areas, cover the bright metal parts with
a heavier coating of wax or preserva-
tive. If necessary, coat the parts with
non-corrosive petroleum jelly or other
protective compound.
Underbody maintenance
Corrosive materials used for ice and
snow removal and dust control may col-
lect on the underbody. If these materials
are not removed, accelerated rusting can
occur on underbody parts such as the
fuel lines, frame, floor pan and exhaust
system, even though they have been
treated with rust protection.
Thoroughly flush the vehicle underbody
and wheel openings with lukewarm or
cold water once a month, after off-road
driving and at the end of each winter. Pay
special attention to these areas because
it is difficult to see all the mud and dirt. It
will do more harm than good to wet down
the road grime without removing it. The
lower edges of doors, rocker panels, and
frame members have drain holes that
should not be allowed to clog with dirt;
trapped water in these areas can cause
rusting.
CAUTION
Wiping dust or dirt off the body with a dry cloth will scratch thefinish.
Do not use steel wool, abrasive cleaners, or strong detergentscontaining highly alkaline orcaustic agents on chrome-platedor anodized aluminum parts. Thismay result in damage to the pro-tective coating and cause discol-oration or paint deterioration.

Maintenance
give particular attention to the compo-
nents under the fenders and other
areas that are hidden from view. Do a
thorough job; just dampening the accu-
mulated mud rather than washing it
away will accelerate corrosion rather
than prevent it. Water under high pres-
sure and steam are particularly effec-
tive in removing accumulated mud and
corrosive materials.
rocker panels and frame members, be
sure that drain holes are kept open so
that moisture can escape and not be
trapped inside to accelerate corrosion.
Keep your garage dry
Don't park your car in a damp, poorly
ventilated garage. This creates a favor-
able environment for corrosion. This is
particularly true if you wash your car in
the garage or drive it into the garage
when it is still wet or covered with snow,
ice or mud. Even a heated garage can
contribute to corrosion unless it is well
ventilated so moisture is dispersed. Keep paint and trim in good condition
Scratches or chips in the finish should be
covered with "touch-up" paint as soon as
possible to reduce the possibility of cor-
rosion. If bare metal is showing through,
the attention of a qualified body and paint
shop is recommended.
Bird droppings : Bird droppings are high-
ly corrosive and may damage painted
surfaces in just a few hours. Always
remove bird droppings as soon as possi-
ble.
Don't neglect the interior
Moisture can collect under the floor mats
and carpeting to cause corrosion. Check
under the mats periodically to be sure
the carpeting is dry. Use particular care if
you carry fertilizers, cleaning materials or
chemicals in the car.
These should be carried only in proper
containers and any spills or leaks should
be cleaned up, flushed with clean water
and thoroughly dried.Interior care
Interior general precautions
Prevent caustic solutions such as per-
fume and cosmetic oil from contacting
the dashboard because they may cause
damage or discoloration. If they do con-
tact the dashboard, wipe them off imme-
diately. See the instructions that follow for
the proper way to clean vinyl.
CAUTION
Never allow water or other liquids
to come in contact with electri-cal/electronic components insidethe vehicle as this may damage them.
When cleaning leather products (steering wheel, seats etc.), useneutral detergents or low alcoholcontent solutions. If you use high alcohol content solutions oracid/alkaline detergents, the colorof the leather may fade or the sur- face may get stripped off.
