Battery recharging
Your vehicle has a maintenance-free,
calcium-based battery.
If the battery becomes discharged in a
short time (because, for example, the
headlights or interior lights were left on
whilst the vehicle was not in use),
recharge it by slow charging (trickle)
for 10 hours.
If the battery gradually discharges because of high electric load whilst the
vehicle is being used, recharge it at 20-
30A for two hours.(Continued)
When lifting a plastic-cased bat-tery, excessive pressure on the
case may cause battery acid to
leak, resulting in personal injury.
Lift with a battery carrier or with
your hands on opposite corners.
Never attempt to recharge the battery when the battery cablesare connected.
The electrical ignition system works with high voltage. Never
touch these components with theengine running or the ignition
switched on.
Failure to follow the above warn-
ings can result in serious bodily
injury or death.CAUTION
When the vehicle will not be used for a long time in a low tempera-
ture area, remove the battery fromthe vehicle and keep it indoors.
Always charge the battery fully to prevent the battery case dam-
aged in low temperature area.
If you connect unauthorised elec- tronic devices to the battery, thebattery may be discharged. Never use unauthorised devices.
WARNING
Removing the battery from the
vehicle should be done by an
authorised HYUNDAI dealer.

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,
another is 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 bemelted.
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 authorised 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 any
other metal object to remove fuses because it may cause a short circuit
and damage the system.

5. Push in a new fuse of the same rating, and make sure it fits tightly in the clips.
If it fits loosely, consult an authorised
HYUNDAI dealer.
If you do not have a spare, use a fuse of the same rating from a circuit you may
not need for operating the vehicle, such as the cigarette lighter fuse.
If the headlights or other electrical com-
ponents do not work and the fuses are
OK, check the fuse panel in the engine
compartment. If a fuse is blown, it mustbe replaced.

vehicle is parked without being operated
for prolonged periods. Use the following
procedures before parking the vehicle for
prolonged periods.

audio, clock and interior lamps, etc.,
will not operate. Some items must be
reset after replacement. Refer to

 Even though the memory fuse is
pulled up, the battery can still be dis-
charged by operation of the head-
lights or other electrical devices.

Maintenance
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.
CAUTION
Wiping dust or dirt off the body with a dry cloth will scratch the
finish.
Do not use steel wool, abrasive cleaners, or strong detergentscontaining highly alkaline orcaustic agents on chrome-plated
or anodized aluminum parts. Thismay result in damage to the pro-tective coating and cause discol-oration or paint deterioration.
CAUTION
Water washing in the engine com-
partment including high pressurewater washing may cause the fail- ure of electrical circuits or engineand related part located in the
engine compartment.
Never allow water or other liquids to come in contact with electri-cal/electronic components and
air duct inside the vehicle as thismay damage them.
