Maintenance
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 roador 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.
- 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 1,800 miles
(3,000km).
CAUTION
It is not easy to recognize tire
damage with your own eyes.
But if there is the slightest
hint of tire damage, have the
tire checked or replaced
because the tire damage may
cause air leakage 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.

A vehicle’s electrical system is pro-
tected from electrical overload dam-
age by fuses.
This vehicle has 2 (or 3) fuse panels,
one located in the driver's side panel
bolster, the other in the engine com-
partment near the battery.
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 or broken.
If the electrical system does not
work, first check the driver's side
fuse panel. Before replacing a blown
fuse, turn the engine and all switches
off, and then disconnect the negative
battery cable. Always replace a
blown fuse with one of the same rat-
ing.
If the replacement fuse blows, this
indicates an electrical problem. Avoid
using the system involved and imme-
diately consult an authorized
HYUNDAI dealer.Information
Three kinds of fuses are used: blade
type for lower amperage rating, car-
tridge type, and fusible link for higher
amperage ratings.

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
NEVER replace a fuse with any-
thing but another fuse of the
same rating.
A higher capacity fuse could
cause damage and possibly
cause a fire.
Do not 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
possibly a fire.

Replacement
1. Turn the engine off.
2. Turn all other switches OFF.
3. Open the fuse panel cover.
4. Refer to the label on the inside ofthe fuse panel cover to locate the
suspected fuse location. 5. Pull the suspected fuse straight
out. Use the removal tool provided
in the engine compartment fuses
panel.
6. Check the removed fuse; replace it if it is blown. Spare fuses are
provided in the instrument panel
fuse panels (or in the engine com-
partment fuse panel).
7. 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. In an emergency, if you do not have
a spare fuse, use a fuse of the same
rating from a circuit you may not
need for operating the vehicle, such
as the cigarette lighter fuse.
If the headlamps or other electrical
components do not work and the
fuses are OK, check the fuse panel
in the engine compartment. If a fuse
is blown, it must be replaced with the
same rating.

Consult an authorized HYUNDAI
dealer to replace most vehicle light
bulbs. 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 for removing the headlamp
assembly to get to the bulb(s).
Removing/installing the headlamp
assembly can result in damage to
the vehicle.
Information
After heavy driving, rain or washing,
headlamp and trunk lenses could
appear frosty. This condition is caused
by the temperature difference
between the lamp inside and the out-
side temperature. This is similar to the
condensation on your windows inside
your vehicle during the rain and does-
n’t indicate a problem with your vehi-
cle. If the water leaks into the lamp
bulb circuitry, have your vehicle
checked by an authorized HYUNDAI
dealer.
Absorbent (if equipped)
This vehicle contains a dehumidify-
ing dehumidifier inside the headlamp
to mitigate the blurring of the head-
lamp due to moisture.
The desiccant is a consumable part
and its performance may change
depending on the usage time or envi-
ronment.
If the inside of the headlamp contin-
ues to become cloudy due to mois-
ture, we recommend that you consult
an authorized HYUNDAI dealer.
The desiccant is a consumable part
and cannot be guaranteed.
i
Prior to replacing a lamp,
depress the foot brake, move
the shift lever into P (Park)
apply the parking brake, place
the igntion switch to the
LOCK/OFF position, and take
the key with you when leaving
the vehicle to avoid sudden
movement of the vehicle and
to prevent possible electric
shock.
Be aware the bulbs may be
hot and may burn your fin-
gers.

Handle halogen bulbs with
care. Halogen bulbs contain
pressurized gas that will pro-
duce flying pieces of glass
that could cause injuries if
broken.
Wear eye protection when
changing a bulb. Allow the
bulb to cool down before han-
dling it.

Maintenance
Always handle them carefully, and avoid scratches and abrasions. 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 immediately
and carefully dispose of it.
1. Open the hood.
2. Disconnect the negative batterycable.
3. Remove the headlamp bulb cover by turning it counterclockwise.
4. Disconnect the headlamp bulb socket-connector. 5. Unsnap the headlamp bulb retain-
ing wire by pressing the end and
pushing it upward.
6. Remove the bulb from the head- lamp assembly.
7. Install a new headlamp bulb and snap the headlamp bulb retaining
wire into position by aligning the
wire with the groove on the bulb.
8. Connect the headlamp bulb sock- et-connector.
9. Install the headlamp bulb cover by turning it clockwise.
Information
The headlamp aiming should be
adjusted after an accident or after the
headlamp assembly is reinstalled at an
authorized HYUNDAI dealer.
Headlamp (LED type)
If the light bulb does not operate, we
recommend that the system be
checked by an authorized HYUNDAI
dealer.
