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 cons
truction 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 y
our 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. igh-corrosion areas
If you live in an area where your vehicle is
r
egularly exposed to corrosive materials,
corrosion protection is particularly
important. Some of the common causes
of accelerated corrosion are road salts,
dust control chemicals, ocean air and
industrial pollution.
Moisture breeds corrosion
Moisture creates the conditions in
which corr
osion is most likely to occur.
For example, corrosion is accelerated
by high humidity, particularly when
temperatures are just above freezing. In
such conditions, the corrosive material is
kept in contact with the vehicle surfaces
by moisture that is slow to evaporate.
Mud is particularly corrosive because
it is slow to dry and holds moisture in
contact with the vehicle. Although the
mud appears to be dry, it can still retain
moisture and promote corrosion.
High temperatures can also accelerate
corrosion of parts that are not properly
ventilated so the moisture can be
dispersed. For all these reasons, it is
particularly important to keep your
vehicle clean and free of mud or
accumulations of other materials. This
applies not only to the visible surfaces
but particularly to the underside of the
vehicle.

9-73
To help prevent corrosion
Keep your vehicle clean
The bes
t way to prevent corrosion is
to keep your vehicle clean and free of
corrosive materials. Attention to the
underside of the vehicle is particularly
important.

[ If you live in a high-corrosion area —
where road salts are used, near the
ocean, areas with industrial pollution,
acid rain, etc.—, you should take extra
care to prevent corrosion. In winter,
hose off the underside of your vehicle
at least once a month and be sure to
clean the underside thoroughly when
winter is over.

[ When cleaning underneath the
vehicle, pay particular attention to the
components under the fenders and
other areas that are hidden from view.
Do a thorough job; just dampening
the accumulated mud rather than
washing it away will accelerate
corrosion rather than prevent it. Water
under high pressure and steam are
particularly effective in removing
accumulated mud and corrosive
materials.

[ When cleaning lower door panels,
rocker panels and frame members, be
sure that drain holes are kept open so
that moisture can escape and not be
trapped inside to accelerate corrosion. Keep your garage dry
Don’t park your vehicle in a damp,
poorly ventilated garage. This creates
a favorable environment for corrosion.
This is particularly true if you wash your
vehicle in the garage or drive it into the
garage when it is still wet or covered with
snow, ice or mud. Even a heated garage
can contribute to corrosion unless it is
well ventilated so moisture is dispersed.
Keep paint and trim in good condition
Scratches or chips in the finish should
be covered with “touch-up” paint as
soon as possible to reduce the possibility
of corrosion. If bare metal is showing
through, the attention of a qualified body
and paint shop is recommended.
Bird droppings are highly corrosive and
may damage painted surfaces in just a
few hours. Always remove bird droppings
as soon as possible.

Maintenance9-74
Interior Care
Interior general precautions
Prevent caustic solutions such as
perfume and cosmetic oil, from
contacting the interior parts because
they may cause damage or discoloration.
If they do contact the interior parts,
wipe them off immediately. See the
instructions for the proper way to clean
vehicle interior surfaces.
NOTICE

[ Never allow water or other liquids
to come in contact with electrical/
electronic components inside the
vehicle as this may damage them.

[ When cleaning leather products
(steering wheel, seats etc.), use
neutral detergents or low alcohol
content solutions. If you use high
alcohol content solutions or acid/
alkaline detergents, the color of the
leather may fade or the surface may
get stripped off.
Cleaning the upholstery and interior
trim
ehicle interior surfaces
Remove dust and loose dirt from interior
surf
aces with a whisk broom or a vacuum
cleaner.
If necessary, clean interior surfaces with
a mixture of warm water and mild non-
detergent cleaner (test all cleaners on a
concealed area before use).
Fabric
Remove dust and loose dirt from
f

abric with a whisk broom or vacuum
cleaner. Clean with a mild soap solution
recommended for upholstery or carpets.
Remove fresh spots immediately with
a fabric spot cleaner. If fresh spots do
not receive immediate attention, the
fabric can be stained and its color can be
affected. Also, its fire-resistant properties
can be reduced if the material is not
properly maintained.
NOTICE
Using anything but recommended
cleaners and procedures may affect the
fabric’s appearance and fire-resistant
properties.

eather

[ F
eatures of seat leather
- Leather is made from the outer skin of an animal, which goes through a
special process to be available for
use. Since it is a natural product,
each part differs in thickness or
density.
Wrinkles may appear as a natural
result of stretching and shrinking
depending on the temperature and
humidity.
- The seat is made of stretchable fabric to improve comfort.
- The parts contacting the body are curved and the side supporting
area is high which provides driving
comfort and stability.
- Wrinkles may appear naturally from usage. It is not a fault of the
products.
NOTICE

[ Wrinkles or abrasions which appear
naturally from usage are not covered
by warranty.

[ Belts with metallic accessories,
zippers or keys inside the back
pocket may damage the seat fabric.

[ Make sure not to wet the seat. It may
change the nature of natural leather.

[ Jeans or clothes which could bleach
may contaminate the surface of the
seat covering fabric.
[
Caring for the leather seats
- Vacuum the seat periodically to remove dust and sand on the seat. It
will prevent abrasion or damage of
the leather and maintain its quality.
- Wipe the natural leather seat cover often with dry or soft cloth.
- Use of proper leather protector may prevent abrasion of the cover and
helps maintain the color. Be sure to
read the instructions and consult
a specialist when using leather
coating or protective agent.

- Light colored (such as beige or
cream beige) leather is easily
contaminated and the stain
is noticeable. Clean the seats
frequently.
- Avoid wiping with wet cloth. It may cause the surface to crack.

[ Cleaning the leather seats
- Remove all contaminations instantly. Refer to instructions below
for removal of each contaminant.
- Cosmetic products (sunscreen, foundation, etc.)
Apply cleansing cream on a cloth
and wipe the contaminated spot.
Wipe off the cream with a wet cloth
and remove water with a dry cloth.
- Beverages (coffee, soft drink, etc.)
Apply a small amount of neutral
detergent and wipe until
contaminations do not smear.
- Oil
Remove oil instantly with
absorbable cloth and wipe with
stain remover used only for natural
leather.
- Chewing gum
Harden the gum with ice and
remove gradually.

Maintenance9-76

[ Handling prime napa leather
Try to avoid excessive sunlight and
heat exposure. Excessive sunlight
and heat exposure naturally fades
and dries out napa leather, causing
wrinkles and discoloration. If the napa
leather is wet with liquid, immediately
clean it with lint-free cloth to minimize
damage. Do not scratch the napa
leather surface with a sharp object.
If your napa leather seat is bright
colored, it may be contaminated or
stained from dyed materials such as
jeans.
Interior wooden trim

[Use a wooden furniture protector (for
example, wax, coating compound) to
clean the interior wooden trim.

[ Wipe the interior wooden trim with a
lint-free, clean cloth to maintain the
unique wooden textures for a longer
period of time.

[ If you spill beverage (for example,
water, coffee) over the interior
wooden trim, immediately wipe it with
clean, dry cloth.

[ Sharp objects (for example, driver,
knife), adhesive materials, or tapes
may damage the interior wooden trim.

[ Any strong impacts may damage the
interior wooden trim.

[ If the coating finish over the interior
wooden trim is removed, moisture
may damage or change wood traits.

[ If the interior wooden trim is
damaged, you may get a splinter
from the wood surface. Therefore,
you should immediately have the
damaged interior wooden trim
replaced by an authorized retailer of
Genesis Branded products.
Cleaning the seat belt webbing
Clean the belt webbing with any
mild soap solution recommended for
cleaning upholstery or carpet. Follow
the instructions provided with the soap.
Do not bleach or re-dye the webbing
because this may weaken the seat belt.
Cleaning the interior window glass
If the interior glass surfaces of the
vehicle become fogged (that is, covered
with an oily, greasy or waxy film), they
should be cleaned with glass cleaner.
Follow the directions on the glass cleaner
container.
NOTICE
Do not scrape or scratch the inside of
the rear window. This may result in
damage to the rear window defroster
grid.

EMISSION CONTROL SYSTEM
The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty
information contained in the Owner’s
Handbook & Warranty Information
booklet in your vehicle.
Your vehicle is equipped with an
emission control system to meet all
applicable emission regulations. There
are three emission control systems, as
follows.
(1) Crankcase emission control system
(2) Evaporative emission control system
(3) Exhaust emission control system
In order to ensure the proper function
of the emission control systems, it
is recommended that you have your
vehicle inspected and maintained by an
authorized retailer of Genesis Branded
products in accordance with the
maintenance schedule in this manual.
NOTICE
For the Inspection and Maintenance
Test (with Electronic Stability Control
(ESC) system)

[ To prevent the vehicle from misfiring
during dynamometer testing, turn
the Electronic Stability Control
(ESC) system off by pressing the ESC
switch (ESC OFF light illuminated).

[ After dynamometer testing is
completed, turn the ESC system back
on by pressing the ESC switch again.
1. Crankcase Emission Control
System
The positive crankcase ventilation system
is employed to prevent air pollution
caused by blow-by gases being emitted
from the crankcase. This system supplies
fresh filtered air to the crankcase through
the air intake hose. Inside the crankcase,
the fresh air mixes with blow-by gases,
which then pass through the PCV valve
into the induction system.
2. Evaporative Emission Control System Including Onboard
Refueling Vapor Recovery
(ORVR)
The Evaporative Emission Control System
is designed to prevent fuel vapors from
escaping into the atmosphere. The
ORVR system is designed to allow the
vapors from the fuel tank to be loaded
into a canister while refueling at the gas
station, preventing the escape of fuel
vapors into the atmosphere.
Canister
Fuel vapors generated inside the fuel
tank are absorbed and stored in the
onboard canister. When the engine is
running, the fuel vapors absorbed in the
canister are drawn into the surge tank
through the purge control solenoid valve.
Purge Control Solenoid Valve (PCSV)
The purge control solenoid valve
is controlled by the Engine Control
Module (ECM); when the engine coolant
temperature is low during idling, the
PCSV closes so that evaporated fuel
is not taken into the engine. After the
engine warms up during ordinary driving,
the PCSV opens to introduce evaporated
fuel to the engine.

Maintenance9-78
3. Exhaust Emission Control System
The Exhaust Emission Control System is
a highly effective system which controls
exhaust emissions while maintaining
good vehicle performance.
When the engine starts or fails to start,
excessive attempts to restart the engine
may cause damage to the emission
system.
Engine exhaust (carbon monoxide)
precautions

[ Carbon monoxide can be present
with other exhaust fumes. If you smell
exhaust fumes of any kind in your
vehicle, drive with all the windows
fully open. Have your vehicle checked
and repaired immediately.
WARNING
Engine exhaust gases contain carbon
monoxide (CO). Though colorless and
odorless, it is dangerous and could be
lethal if inhaled. Follow the instructions
on this page to avoid CO poisoning.
WARNING
CALIFORNIA PROPOSITION 65
WARNING
Engine exhaust and a wide variety of
automobile components and parts,
including components found in the
interior furnishings in a vehicle, contain
or emit chemicals known to the State
of California to cause cancer and
birth defects and reproductive harm.
In addition, certain fluids contained
in vehicles and certain products of
component wear contain or emit
chemicals known to the State of
California to cause cancer and birth
defects or other reproductive harm.
Do not operate the engine in confined
or closed areas (such as garages) any
more than what is necessary to move the
vehicle in or out of the area.

[When the vehicle is stopped in an
open area for more than a short time
with the engine running, adjust the
ventilation system (as needed) to draw
outside air into the vehicle.

[ Never sit in a parked or stopped
vehicle for any extended time with the
engine running.

[ When the engine stalls or fails to
start, excessive attempts to restart
the engine may cause damage to the
emission control system.
