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), jump
start it from another vehicle’s battery or
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.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 battery andstore it indoors.
Always charge the battery fully to prevent the battery case dam-aged in low temperatures.
If you connect unauthorized elec- tronic devices to the battery, thebattery may be discharged. 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.

Compact spare tire replacement
A compact spare tire has a shorter
tread life than a regular size tire.
Replace it when you can see the
tread wear indicator bars on the tire.
The replacement compact spare tire
should be the same size and design
tire as the one provided with your
new vehicle and should be mounted
on the same compact spare tire
wheel. The compact spare tire is not
designed to be mounted on a regular
size wheel, and the compact spare
tire wheel is not designed for mount-
ing a regular size tire. Wheel replacement
When replacing the metal wheels for
any reason, make sure the new
wheels are equivalent to the original
factory units in diameter, rim width
and offset.
Tire traction
Tire traction can be reduced if you
drive on worn tires, tires that are
improperly inflated or on slippery
road surfaces. Tires should be
replaced when tread wear indicators
appear. To reduce the possibility of
losing control, slow down whenever
there is rain, snow or ice on the road.
Tire maintenance
In addition to proper inflation, correct
wheel alignment helps to decrease
tire wear. If you find a tire is worn
unevenly, have your dealer check the
wheel alignment.
When you have new tires installed,
make sure they are balanced. This
will increase vehicle ride comfort and
tire life. Additionally, a tire should
always be rebalanced if it is removed
from the wheel.
WARNING
A wheel that is not the correct
size may adversely affect wheel
and bearing life, braking and
stopping abilities, handling char-
acteristics, ground clearance,
body-to-tire clearance, snow
chain clearance, speedometer
and odometer calibration, head-
light aim and bumper height.

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, 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.
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 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 anyother metal object to remove fuses because it may cause a short circuitand damage the system.

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.
Engine compartment fuse
replacement
1. Turn the engine start/stop button and
all other switches off.
2. Remove the fuse panel cover by pressing the tab and pulling up. 3. Check the removed fuse; replace it if it
is blown. To remove or insert the fuse,
use the fuse puller in the engine com-
partment fuse panel.
4. Push in a new fuse of the same rating, and make sure it fits tightly in the clips.
If it fits loosely, consult an authorized
HYUNDAI dealer.

LIGHT BULBS
Use only 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
apply the parking brake, ensure
that the engine start/stop button is
turned to the LOCK position and
turn off the lights to avoid sudden
movement of the vehicle and burn-
ing your fingers or receiving an
electric shock.
CAUTION
Be sure to replace the burned-out
bulb with one of the same wattagerating. Otherwise, it may causedamage to the fuse or electric wiring 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 bulbsbecause 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).
Removing/installingthe headlight
assembly can result in damage to the vehicle.
WARNING
When you replace the bulb of front-
light, be careful the HPCU system,
high voltage cable (orange color)
and high voltage components for
hybrid.
It is very dangerous because the
HPCU has the high voltage. Always
pay strongly attention to your
hands. If not, it may result in the
electric shock or burns.

WARNING- Halogen bulbs
Halogen bulbs contain pressur-ized gas that will produce flying
pieces of glass if broken.
Always handle them carefully, and avoid scratches and abra-
sions. If the bulbs are lit, avoid
contact with liquids. Never touch
the glass with bare hands.
Residual oil may cause the bulb
to overheat and burst when lit. A
bulb should be operated only
when installed in a headlight.
