2020 GENESIS G90 check engine light

7-52
Maintenance
A vehicle's electrical system is pro-
tected from electrical overload dam-
age by fuses.
This vehicle has 4 fuse panels, one
located in the driver's side panel bol-
ster, another in the engine compart-
ment, and two others in the trunk
compartment.
If any of your vehicle's lights, acces-
sories, 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 rat-
ing.
If the replacement fuse blows, this
indicates an electrical problem. Avoid
using the system involved and imme-
diately consult an authorized retailer
of Genesis Branded products.
Information
Four kinds of fuses are used: blade
type for lower amperage rating, car-
tridge type, multi fuse and fusible link
for higher amperage ratings.
Do not use a screwdriver or any
other metal object to remove
fuses because it may cause a
short circuit and damage the sys-
tem.

NEVER replace a fuse with any-
thing but another fuse of the
same rating.
A higher capacity fuse couldcause damage and possibly
cause a fire.
Do not install a wire or alu- minum foil instead of the
proper fuse - even as a tempo-
rary repair. It may cause
extensive wiring damage and
possibly a fire.

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.
