climate control air filter, replace it per-
forming the following procedure, and be
careful to avoid damaging other compo-
nents.
Filter replacement

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)
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 the engine 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 120°F (49°C).

FUSES
A vehicle’s electrical system is protected
from electrical overload damage by
fuses.
This vehicle has 3 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, accessories,
or controls do not work, check the appro-
priate circuit fuse. If a fuse has blown, the element inside the fuse will melt.
If the electrical system does not work,
first check the driver’s side fuse panel.
Before replacing a blown fuse, discon-
nect the negative battery cable.
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.
Four kinds of fuse are used: blade type,cartridge type, multi fuse and main fuse.
✽✽ NOTICE
The actual fuse/relay panel label may
differ from equipped items.
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 fusesbecause it may cause a short circuit
and damage the system.

CAUTION
When replacing a blown fuse or
relay with a new one, make surethe new fuse or relay fits tightly
into the clips. The incomplete fas-tening fuse or relay may cause the vehicle wiring and electricsystems damage and a possible
fire.
Do not remove fuses, relays and terminals fastened with bolts or
nuts. The fuses, relays and termi-nals may be fastened incomplete-ly, and it may cause a possible fire. If fuses, relays and terminals
fastened with bolts or nuts are blown, consult with an authorizedHYUNDAI dealer.
Do not input any other objects except fuses or relays intofuse/relay terminals such as adriver or wiring. It may cause con-
tact failure and system malfunc-tion.
