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
After driving in heavy rain or washing
the vehicle, headlamp and trunk lenses
could appear frosty. This condition is
caused by the temperature difference
between the lamp inside and the out-
side temperature. This is similar to the
condensation on your windows inside
your vehicle when it rains and doesn't
indicate a problem with your vehicle.
If the water leaks into the lamp bulb
circuitry, have your vehicle checked
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 fin-
gers.

Do not use strong soap, chemi-
cal detergents or hot water, and
do not wash the vehicle in direct
sunlight or when the body of the
vehicle is warm.
Be careful when washing the side windows of your vehicle.
Especially, with high-pressure
water, water may leak through
the windows and wet the interior.
To prevent damage to the plastic parts, do not clean with chemi-
cal solvents or strong deter-
gents.
Water washing in the engine compartment including high
pressure water washing may
cause the failure of electrical cir-
cuits located in the engine com-
partment.
Never allow water or other liq- uids to come in contact with
electrical/electronic compo-
nents inside the vehicle as this
may damage them. Matte paint finish vehicle
(if equipped)
Automatic car wash which uses
rotating brushes should not be
used as this can damage the sur-
face of your vehicle. A steam
cleaner which washes the vehicle
surface at high temperature may
result the oil to adhere and leave
stains that is difficult to remove.
Use a soft cloth (e.g. microfiber
towel or sponge) when washing
your vehicle and dry with a
microfiber towel. When you hand
wash your vehicle, you should not
use a cleaner that finishes with
wax. If the vehicle surface is too
dirty (sand, dirt, dust, contami-
nant, etc.), clean the surface with
water before washing the car.
Waxing
A good coat of wax provides a barri-
er between your paint and environ-
mental contamination.
Keeping a good coat of wax on your
vehicle will help protect it.
Wax the vehicle when water will no
longer bead on the paint.
Always wash and dry the vehicle
before waxing. Use a good quality
liquid or paste wax, and follow the
manufacturer’s instructions. Wax all
metal trim to protect it and to main-
tain its luster.
Removing oil, tar, and similar materi-
als with a spot remover will usually
strip the wax from the finish. Be sure
to re-wax these areas even if the rest
of the vehicle does not yet need wax-
ing.
