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.

Maintenance
High-pressure washing

[When using high-pressure washers,
make sure to maintain sufficient
distance from the vehicle.
Insufficient clearance or excessive
pressure can lead to component
damage or water penetration.

[Do not spray the camera, sensors or
its surrounding area directly with a
high pressure washer. Shock applied
from high pressure water may cause
the device to not operate normally.

[Do not bring the nozzle tip close to
boots (rubber or plastic covers) or
connectors as they may be damaged
if they come into contact with high
pressure water.
WARNING
After washing the vehicle, test the
brakes while driving slowly to see
if they have been affected by water
before getting on the road. If braking
performance is impaired, dry the
brakes by applying them lightly while
maintaining a slow forward speed.
NOTICE

[Do not use strong soap, chemical
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 chemical
solvents or strong detergents.
NOTICE
ORS091047

[Water washing in the engine
compartment including high
pressure water washing may cause
the failure of electrical circuits
located in the engine compartment.

[Never allow water or other liquids
to come in contact with electrical/
electronic components inside the
vehicle as this may damage them.
NOTICE
Matte paint finish vehicle (if equipped)
Automatic car wash which uses rotating
brushes should not be used as this can
damage the surface of your vehicle. A
steam cleaner which washes the vehicle
surface at high temperature may cause
the oil to adhere and leave stains that is
difficult to remove.
Use a soft cloth (for example, 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.

Maintenance
Bright-metal maintenance

[To remove road tar and insects, use
a tar remover, not a scraper or other
sharp object.

[To protect the surfaces of brightmetal
parts from corrosion, apply a coating
of wax or chrome preservative and rub
to a high luster.

[During winter weather or in coastal
areas, cover the bright metal parts
with a heavier coating of wax or
preservative. If necessary, coat the
parts with non-corrosive petroleum
jelly or other protective compound.
Underbody maintenance
Corrosive materials used for ice and
snow removal and dust control may
collect on the underbody. If these
materials are not removed, accelerated
rusting can occur on underbody parts
such as the fuel lines, frame, floor pan
and exhaust system, even though they
have been treated with rust protection.
Thoroughly flush the vehicle underbody
and wheel openings with lukewarm or
cold water once a month, after off-road
driving and at the end of each winter.
Pay special attention to these areas
because it will do more harm than good
if the road grime becomes wet without
removing it. The lower edges of doors,
rocker panels, and frame members have
drain holes that should not be allowed
to clog with dirt; trapped water in these
areas can cause rusting.
WARNING
After washing the vehicle, test the
brakes while driving slowly to see if
they have been affected by water. If
braking performance is impaired, dry
the brakes by applying them lightly
while maintaining a slow forward
speed.
Aluminum wheel maintenance
The aluminum wheels are coated with a
clear protective finish.

[Do not use abrasive cleaner, polishing
compound, solvent, or wire brushes
on aluminum wheels.

[Clean the wheel when it has cooled.

[Use only a mild soap or neutral
detergent, and rinse thoroughly with
water. Also, clean the wheels after
driving on salted roads.

[Do not wash the wheels with high-
speed car wash brushes.

[Do not use any cleaners containing
acid or alkaline detergents.
Corrosion protection
Protecting your vehicle from corrosion
By using the most advanced design
and construction practices to combat
corrosion, Genesis Branded Vehicle
produces vehicles of the highest quality.
However, this is only part of the job.
To achieve the long-term corrosion
resistance, the owner’s cooperation and
assistance is also required.
Common causes of corrosion
The most common causes of corrosion
on your vehicle are:

[Road salt, dirt and moisture that is
allowed to accumulate underneath
the vehicle.

[Removal of paint or protective
coatings by stones, gravel, abrasion
or minor scrapes and dents which
leave unprotected metal exposed to
corrosion.
