12V Battery recharging
Your vehicle has a maintenance-free,
calcium-based battery.
If the 12V battery becomes discharged
in a short time (because, for example,
the headlights or interior lights were
left on while the vehicle was not in
use), jump start it from another vehi-
cle’s 12V battery or recharge it by slow
charging (trickle) for 10 hours.
If the 12V battery gradually discharges
because of high electric load while the
vehicle is being used, recharge it at 20-
30A for two hours.CALIFORNIA PROPOSI-
TION 65 WARNING
Battery posts, terminals, and relat-
ed accessories contain lead and
lead compounds, chemicals known
to the State of California to cause
cancer, birth defects and reproduc-
tive harm. Batteries also contain
other chemicals known to the State
of California to cause cancer. Wash
hands after handling.
CAUTION
When you don’t use the vehicle
for a long time in the low temper-
ature, remove the 12V battery and
store it indoors.
Always charge the 12V battery
fully to prevent 12V battery case
damage in low temperatures.
If you connect unauthorized elec-
tronic devices to the 12V battery,
the 12V battery may be dis-
charged. Never use unauthorized
devices.
(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 cables
are connected.
The electrical ignition system
works with high voltage. Never
touch these components with the
engine running or the engine
start/stop button positioned on.
Failure to follow the above warn-
ings can result in serious bodily
injury or death.

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, accessories,
or controls do not work, check the appro-
priate 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, 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.
Three kinds of fuses are used: blade type
for lower amperage rating, cartridge type,
and multi fuse for higher amperage ratings.
✽ ✽
NOTICE
The actual fuse/relay panel label may
differ from equipped items.
WARNING - Fuse
replacement
Never replace a fuse with anything
but another fuse of the same rat-
ing.
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.
CAUTION
When replacing a blown fuse or
relay with a new one, make sure
the new fuse or relay fits tightly
into the clips. The incomplete fas-
tening fuse or relay may cause the
vehicle wiring and electric sys-
tems 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 authorized
HYUNDAI dealer.
Do not input any other objects
except fuses or relays into
fuse/relay terminals such as a driv-
er or wiring. It may cause contact
failure and system malfunction.

Finish maintenance
Washing
To help protect your vehicle’s finish from
rust and deterioration, wash it thoroughly
and frequently at least once a month with
lukewarm or cold water.
If you use your vehicle for off-road driv-
ing, you should wash it after each off-
road trip. Pay special attention to the
removal of any accumulation of salt, dirt,
mud, and other foreign materials. Make
sure the drain holes in the lower edges of
the doors and rocker panels are kept
clear and clean.
Insects, tar, tree sap, bird droppings,
industrial pollution and similar deposits
can damage your vehicle’s finish if not
removed immediately.
Even prompt washing with plain water
may not completely remove all these
deposits. A mild soap, safe for use on
painted surfaces, may be used.After washing, rinse the vehicle thor-
oughly with lukewarm or cold water. Do
not allow soap to dry on the finish.
CAUTION
Do not use strong soap, chemical
detergents or hot water, and do
not wash the vehicle in direct
sunlight or when the body of the
vehicle is warm.
Be careful when washing the side
windows of your vehicle.
Especially, with high-pressure
water, water may leak through the
windows and wet the interior.
To prevent damage to the plastic
parts and lamps, do not clean
with chemical solvents or strong
detergents.
WARNING
Do not wash the engine compart-
ment and trunk with water. The
hybrid system is located in the
engine compartment and trunk. If
