FUSES
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.
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 bat-
tery 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 immedi-
ately consult an authorized HYUNDAI
dealer.
Information
Three kinds of fuses are used:
blade type for lower amperage rat-
ing, cartridge type and multi fuse
for higher amperage ratings.

Maintenance
Inner panel fuse replacement
1. Turn the engine and all other
switches off.
2. Open the fuse panel cover.
3. Pull the suspected fuse straight
out. Use the removal tool provided
in the engine compartment fuse
panel.
4. Check the removed fuse; replace it
if it is blown.
5. Push in a new fuse of the same
rating, and make sure it fits tightly
in the clips.
If it fits loosely, we recommend that
you consult an authorized HYUNDAI
dealer.
Information
If you do not have a spare, use a
fuse of the same rating from a cir-
cuit you may not need for operat-
ing the vehicle, such as the cigar
lighter fuse.
If the headlights or other electrical
components do not work and the
fuses are OK, check the fuse block in
the engine compartment. If a fuse is
blown, it must be replaced with the
same rating.

LIGHT BULBS
Use only the bulbs of the specified
wattage.
After heavy driving, rain or wash-
ing, headlamp and tail lamp lens-
es could appear frosty. This condi-
tion is caused by the temperature
difference between the lamp
inside and outside. This is similar
to the condensation on your win-
dows inside your vehicle during
the rain and doesn’t indicate a
problem with your vehicle. If the
water leaks into the lamp bulb cir-
cuitry, we recommend that the
system be checked by an author-
ized HYUNDAI dealer.
❈Traffic Change (For Europe)
The low beam light distribution is
asymmetric. If you go abroad to a
country with opposite traffic direc-
tion, this asymmetric part will dazzle
oncoming car driver. To prevent daz-
zle, ECE regulation demand several
technical solutions (ex. automatic
change system, adhesive sheet,
down aiming). These headlamps are
designed not to dazzle opposite driv-
ers. So, you need not change your
headlamps in a country with oppo-
site traffic direction.
NOTICE
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, 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 headlamp
assembly to get to the bulb(s).
Removing/installing the head-
lamp assembly can result in
damage to the vehicle.
CAUTION
Working on the lights
Prior to working on the light, firm-
ly apply the parking brake,
ensure that the Engine Start/Stop
button is turned to the OFF posi-
tion and turn off the lights to
avoid sudden movement of the
vehicle and burning your fingers
or receiving an electric shock.
