Consult an authorized retailer of
Genesis Branded products 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
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 con-
dition. However, if moisture is not
removed, we recommend that your
vehicle is inspected by an authorized
retailer of Genesis Branded products.Light replacement
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.
To prevent damage, do not clean
the headlamp with chemical sol-
vents or strong detergents.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, have the system
checked by an authorized retailer of
Genesis Branded products.
• The parking lamp may not turn on
when the parking lamp switch is
turned on, but the parking 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,
have the system checked by an
authorized retailer of Genesis
Branded products.

• Prior to replacing a lamp,
depress the foot brake, shift
the gear to P (Park) apply the
parking brake, place the
Engine Start/Stop button to
the 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.
