Motor compartment fuse panel(Battery terminal cover)
Inside the fuse/relay box cover, you
can find the fuse/relay label describ-
ing fuse/relay name and capacity.

After checking the fuse panel in the motor compartment, securely
install the cover. If it is not securely latched, electrical failure may occur
from water contact.

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
The headlamp and tail lamp lenses
could appear frosty if the vehicle is
washed after driving or the vehicle is
driven at night in wet weather. This
condition is caused by temperature dif-
ference between the lamp inside and
outside and, it does not indicate a prob-
lem with your vehicle. When moisture
condenses in the lamp, it will be
removed after driving with the head-
lamp on. The removable level may dif-
fer depending on lamp size, lamp posi-
tion and environmental condition.
However, if moisture is not removed, we
recommend that your vehicle is inspect-
ed by an authorized HYUNDAI dealer. Information
 A normally functioning lamp may flicker momentarily to stabilize the
vehicle’s electrical control system.
However, if the lamp goes out after
flickering momentarily, or contin-
ues to flicker, we recommend the
system be checked by an authorized
HYUNDAI dealer.
 The position lamp may not turn on when the position lamp switch is
turned on, but the position lamp and
headlamp switch may turn on when
the headlamp switch is turned on.
This may be caused by network fail-
ure or vehicle electrical control sys-
tem malfunction. If this occurs, we
recommend the system be checked
by an authorized HYUNDAI dealer.i
i
Prior to replacing a lamp,
depress the foot brake, shift
to P (Park), apply the parking
brake, place the POWER but-ton in the OFF position and
take the key with you when
leaving the vehicle to avoid
sudden movement of the vehi-
cle and to prevent possible
electric shock.
Be aware the bulbs may be
hot and may burn your fin-
gers.

Type A– Standard type
(1) Headlamp (Low) (2) Headlamp (High)
(3) Turn signal lamp
(4) Parking lamp
(5) Side marker 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 immediatelyand carefully dispose of it.

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

Information
If your vehicle is equipped with High
Intensity Discharge (HID) headlamps,
these headlamps contain mercury. So
if you need to have your vehicle dis-
posed, you should remove the HID
Headlamps before disposal. The
removed HID headlamps should be
recycled, re-used or disposed as haz-
ardous waste. Information
HID lamps have superior perform-
ance vs. halogen bulbs.
HID lamps are estimated by the man-
ufacturer to last twice as long or
longer than halogen bulbs depending
on their frequency of use. They will
probably require replacement at some
point in the life of the vehicle. Cycling
the headlamps on and off more than
typical use will shorten HID lamps
life. HID lamps do not fail in the same
manner as halogen incandescent
lamps. If a headlamp goes out after a
period of operation but will immedi-
ately relight when the headlamp
switch is cycled it is likely the HID
lamp needs to be replaced. HID light-
ing components are more complex
than conventional halogen bulbs thus
have higher replacement cost.
Information
The headlamp aiming should be
adjusted after an accident or after the
headlamp assembly is reinstalled at an
authorized HYUNDAI dealer.Turn signal lamp
