A : Blade type,

O: Normal, X: Blown
A vehicle’s electrical system is protected
from electrical overload damage by
fuses.
This vehicle has 5 fuse panels, one
located in the driver’s side panel bolster,
the other in the engine compartment.
If any of your vehicle’s lights,
accessories, or controls do not work,
check the appropriate circuit fuse. If a
fuse has blown, the element inside the
fuse will be melted or broken.
If the electrical system does not work,
first check the driver’s side fuse panel.
Before replacing a blown fuse, turn the
engine and all switches off, and then
disconnect the negative battery cable.
Always replace a blown fuse with one of
the same rating.
If the replacement fuse blows, this
indicates an electrical problem.
Avoid using the system involved and
immediately consult an authorized
retailer of Genesis Branded products.
WARNING
NEVER replace a fuse with anything but
another fuse of the same rating.

[A higher capacity fuse could cause
damage and possibly cause a fire.

[Do not install a wire or aluminum
foil instead of the proper fuse -
even as a temporary repair. It may
cause extensive wiring damage and
possibly a fire.
NOTICE
Do not use a screwdriver or any other
metal object to remove fuses because
it may cause a short circuit and damage
the system.

Maintenance
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
headlight assembly to get to the bulb(s).
Removing/installing the headlight
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, press the Engine
Start/Stop button to the OFF position
and take the smart 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
headlight lens with chemical solvents
or strong detergents.
Information
The headlight 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 headlight
on. The removable level may differ
depending on lamp size, lamp position
and environmental condition. However, if
moisture is not removed, have the vehicle
inspected by an authorized retailer of
Genesis Branded products.
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, 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 headlight
switch may turn on when the headlight
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.
Information
The headlight aiming should be adjusted
after an accident or after the headlight
assembly is reinstalled at an authorized
retailer of Genesis Branded products.
