Maintenance
Battery recharging
Your vehicle has a maintenance-free,
calcium-based battery.
• If the battery becomes discharged
in a short time (because, for exam-
ple, the headlights or interior lights
were left on while 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 while
the vehicle is being used, recharge
it at 20-30A for two hours.(Continued)
1. Turn off the battery charger
main switch.
2. Unhook the negative clamp
from the negative battery ter-
minal.
3. Unhook the positive clamp
from the positive battery ter-
minal.WARNING- Recharging
battery
When recharging the battery,
observe the following precau-
tions:
• The battery must be removed
from the vehicle and placed in
an area with good ventilation.
• Do not allow cigarettes,
sparks, or flame near the bat-
tery.
• Watch the battery during
charging, and stop or reduce
the charging rate if the battery
cells begin gassing (boiling)
violently or if the temperature
of the electrolyte of any cell
exceeds 49°C (120°F).
• Wear eye protection when
checking the battery during
charging.
• Disconnect the battery charg-
er in the following order.

FUSES
A vehicle’s electrical system is pro-
tected from electrical overload dam-
age by fuses.This vehicle has 4 fuse panels, one
located in the driver’s side panel bol-
ster, another is in the front passen-
ger’s side panel bolster, the others
are 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.
Before replacing a blown fuse, dis-
connect the negative battery cable.
Always replace a blown fuse with
one of the same rating.
If the replacement fuse blows, this
indicates an electrical problem. Avoid
using the system involved and we
recommend that you consult an
authorized HYUNDAI dealer.Three kinds of fuses are used: blade
type for lower amperage rating, car-
tridge type, and fusible link for higher
amperage ratings.
✽NOTICE
The actual fuse/relay panel label
may differ from equipped items.
WARNING - Fuse
replacement
• 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 alu-
minum foil instead of the
proper fuse - even as a tem-
porary 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.

LIGHT BULBS
Use only the bulbs of the specified
wattage.
✽NOTICE
After heavy, driving rain or wash-
ing, headlamp and taillight lenses
could appear frosty. This condition
is caused by the temperature differ-
ence between the lamp inside and
outside. This is similar to the con-
densation on your windows inside
your vehicle during the rain and
doesn’t indicate a problem with
your vehicle. If the water leaks into
the lamp bulb circuitry, we recom-
mend that the system be checked by
an authorized HYUNDAI dealer.WARNING - Working on
the lights
Prior to working on the light,
firmly apply the parking brake,
ensure that the ignition switch
is turned to the LOCK position
and turn off the lights to avoid
sudden movement of the vehi-
cle and burning your fingers or
receiving an electric shock.
CAUTION
Be sure to replace the burned-
out bulb with one of the same
wattage rating. Otherwise, it
may cause damage to the fuse
or electric wiring system.
CAUTION
If you don’t have necessary
tools, the correct bulbs and the
expertise, we recommend that
you consult an authorized
HYUNDAI dealer. In many cases,
it is difficult to replace vehicle
light bulbs because other parts
of the vehicle must be removed
before you can get to the bulb.
This is especially true if you
have to remove the headlam-
passembly to
get to the bulb(s).
Removing/installing
the head-
lamp assembly can result in
damage to the vehicle.
