Maintenance
Battery recharging
Your vehicle has a maintenance-free,
calcium-based battery.
If the battery becomes discharged in ashort time (because, for example, 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)
Never attempt to recharge thebattery when the battery cables are 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.WARNING - Recharging
battery
When recharging the battery,
observe the following precautions:
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 battery.
Watch the battery during charg- ing, and stop or reduce the charg-
ing 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 check- ing the battery during charging.
Disconnect the battery charger in the following order.
1. Turn off the battery charger main switch.
2. Unhook the negative clamp from the negative battery terminal.
3. Unhook the positive clamp from the positive battery terminal.

Maintenance
FUSES
A vehicle’s electrical system is protected
from electrical overload damage by
fuses. This vehicle has 4 fuse panels, one locat-
ed in the driver’s side panel bolster,
another is in the front passenger’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 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 authorized HYUNDAI dealer.
Three kinds of fuses are used: blade type
for lower amperage rating, cartridge type,and fusible link 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 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 circuitand damage the system.

Maintenance
Memory fuse
Your vehicle is equipped with a memory
fuse to prevent battery discharge if your
vehicle is parked without being operated
for prolonged periods. Use the following
procedures before parking the vehicle for
prolonged periods.
1. Turn the engine start/stop button off.
2. Turn off the headlights and tail lights.
3. Open the driver’s side panel cover andpull up the memory fuse.
✽✽ NOTICE
 If the memory fuse is pulled up from the fuse panel, the warning chime,
audio, clock and interior lamps, etc.,
will not operate. Some items must be
reset after replacement. Refer to
“Battery” in this section.
 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.

LIGHT BULBS
Use only the bulbs of the specified
wattage.
✽✽ NOTICE
After heavy, driving rain or washing,
headlight and taillight lenses could
appear frosty. This condition is caused by
the temperature difference between the
lamp inside and outside. This is similar
to the condensation 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, have the vehicle checked
by an authorized HYUNDAI dealer.

WARNING - Working on
the lights
Prior to working on the light, firmly

that the ignition switch is turned tothe LOCK position and turn off the
lights to avoid sudden movement
of the vehicle and burning your fin-
gers or receiving an electric shock.
CAUTION

rating. Otherwise, it may causedamage to the fuse or electricwiring system.
CAUTION
If you don’t have necessary tools,the correct bulbs and the expertise,
consult an authorized HYUNDAIdealer. In many cases, it is difficultto replace vehicle light bulbs because other parts of the vehicle
must be removed before you canget to the bulb. This is especiallytrue if you have to remove the head-
light assembly to
get to the bulb(s).
