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

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. Slow down whenever there
is rain, snow or ice on the road, to
reduce the possibility of losing con-
trol of the vehicle.
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.
Tire sidewall labeling
This information identifies and
describes the fundamental charac-
teristics of the tire and also provides
the tire identification number (TIN)
for safety standard certification. The
TIN can be used to identify the tire in
case of a recall.
1. Manufacturer or brand name
Manufacturer or Brand name is
shown.
WARNING
A wheel that is not the correct
size may adversely affect wheel
and bearing life, braking and
stopping abilities, handling
characteristics, ground clear-
ance, body-to-tire clearance,
snow chain clearance,
speedometer and odometer cal-
ibration, headlight aim and
bumper height.

Temperature -A, B & C
The temperature grades are A (the
highest), B, and C, representing the
tire’s resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled condi-
tions on a specified indoor laboratory
test wheel. Sustained high tempera-
ture can cause the material of the tire
to degenerate and reduce tire life,
and excessive temperature can lead
to sudden tire failure. Grades B and
A represent higher levels of perform-
ance on the laboratory test wheel
than the minimum required by law.Low aspect ratio tire
(if equipped)
Low aspect ratio tires, whose aspect
ratio is lower than 50, are provided
for sporty looks.
Because the low aspect ratio tires
are optimized for handling and brak-
ing, it may be more uncomfortable to
ride in and there is more noise com-
pare with normal tires.
WARNING - Tire
temperature
The temperature grade for this
tire is established for a tire that
is properly inflated and not
overloaded. Excessive speed,
underinflation, or excessive
loading, either separately or in
combination, can cause heat
build-up and sudden tire failure.
This can cause loss of vehicle
control and serious injury or
death.
CAUTION
Because the sidewall of the low
aspect ratio tire is shorter than
the normal, the wheel and tire of
the low aspect ratio tire is easi-
er to be damaged. So, follow the
instructions below.
- When driving on a rough road
or off road, drive cautiously
because tires and wheels may
be damaged. And after driving,
inspect tires and wheels.
- When passing over a pothole,
speed bump, manhole, or curb
stone, drive slowly so that the
tires and wheels are not dam-
aged.
(Continued)
CAUTION
• It is not easy to recognize the
tire damage with your own
eyes. But if there is the slight-
est hint of tire damage, even
though you cannot see the tire
damage with your own eyes,
have the tire checked or
replaced because the tire
damage may cause air leak-
age from the tire.
• If the tire is damaged by driv-
ing on a rough road, off road,
pothole, manhole, or curb
stone, it will not be covered by
the warranty.
• You can find out the tire infor-
mation on the tire sidewall.
(Continued)
- If the tire is impacted, we rec-
ommend that you inspect the
tire condition or contact an
authorized HYUNDAI dealer.
- To prevent damage to the tire,
inspect the tire condition and
pressure every 3,000km.

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.

✽NOTICE
HID/LED lamps have superior per-
formance vs. halogen bulbs.
HID/LED lamps are estimated by
the manufacturer to last twice as
long or longer than halogen bulbs
depending on their frequency of use.
They will probably require replace-
ment at some point in the life of the
vehicle. Cycling the headlamps on
and off more than typical use will
shorten HID/LED lamps life. HID/
LED lamps do not fail in the same
manner as halogen incandescent
lamps. If a headlamp goes out after
a period of operation but will imme-
diately relight when the headlamp
switch is cycled it is likely the
HID/LED lamp needs to be
replaced. HID/LED lighting compo-
nents are more complex than con-
ventional halogen bulbs thus have
higher replacement cost.

WARNING - Halogen
bulbs
• Halogen bulbs contain pres-
surized gas that will produce
flying pieces of glass if bro-
ken.
(Continued)
(Continued)
• 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 headlamp.
• If a bulb becomes damaged or
cracked, replace it immediate-
ly and carefully dispose of it.
• Wear eye protection when
changing a bulb. Allow the
bulb to cool down before han-
dling it.
