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

If the LED lamp does not operate,
we recommend that the system be
inspected by a HYUNDAI authorised
repairer.
The LED lamps cannot be replaced as
a single unit because it is an integrated
unit. The LED lamp has to be replaced
with the unit. Unless a skilled technician
checks or repairs the LED lamp, it may
damage related parts of the vehicle.
