We recommend that you 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.
WARNING
• Prior to working on a light, depress
the foot brake, shift to P (Park), apply
the parking brake, set the ignition
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 fingers.
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 electrical wiring system.
NOTICE
To prevent damage, do not clean the
headlamp lens with chemical solvents
or strong detergents.
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 difference between the
lamp inside and outside and, it does not
indicate a problem with your vehicle.
When moisture condenses in the lamp,
it will be removed after driving with the
headlamp on. The removable level may
differ depending on lamp size, lamp
position and environmental condition.
However, if moisture is not removed, we
recommend that your vehicle is inspected
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 continues 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 failure or vehicle electrical
control system malfunction. If this
occurs, we recommend the system be
checked by an authorized HYUNDAI
dealer.
Information
The headlamp aiming should be adjusted
after an accident or after the headlamp
assembly is reinstalled at an authorized
HYUNDAI dealer.

bulb align with the slots in the socket.
Pull the bulb out of the socket.
5. Install a new bulb by inserting it into
the socket and rotating it until it locks
into place.
6. Push the socket into the assembly and
turn the socket clockwise.
7. Install the wheel guard in the reverse
order.

• 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.
Lamps
If the LED lamp does not operate, we
recommend that you have the vehicle
checked by an authorized HYUNDAI
dealer.
Side repeater lamp replacement
OTM090023
If the LED lamp (1) does not operate,
we recommend that the system be
inspected by an authorized HYUNDAI
dealer.
The LED lamps cannot be replaced as
a single unit because it is an integrated
unit. The LED lamps has to be replaced
with the unit.
A skilled technician should check or
repair the LED lamp, for it may damage
related parts of the vehicle.
