We recommend that you consult with a
HYUNDAI authorised repairer 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
headlight assembly to get to the bulb(s).
Removing/installing the headlight
assembly can result in damage to the
vehicle.
WARNING
Prior to replacing a light, depress the
foot brake, move the shift lever into the
N (Neutral, for automatic transmission
vehicle) or neutral (for manual
transmission vehicle), apply the parking
brake, place the ignition switch in 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.

Otherwise, it may cause damage to the

WARNING
[ Handle halogen bulbs with care.
Halogen bulbs contain pressurized
gas that will produce flying pieces
of glass that could cause injuries if
broken.
[ Wear eye protection when changing
a bulb. Allow the bulb to cool down
before handling it.
[ 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 headlight.
[ If a bulb becomes damaged or
cracked, replace it immediately and
carefully dispose of it.

The low beam light distribution is
asymmetric. If you go abroad to a
country with opposite traffic direction,
this asymmetric part will dazzle
oncoming car driver. To prevent dazzle,
ECE regulation demands several
technical solutions (ex. automatic
change system, adhesive sheet, down
aiming). This headlamps are designed
not to dazzle opposite drivers.
So, you need not change your
headlamps in a country with the
opposite traffic direction.
