Leather (if equipped)
• Features 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 nat-
ural 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 driv-
ing comfort and stability.
- Wrinkles may appear naturally
from usage. It is not a fault of the
product.
• 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 natu-
ral leather.
• Jeans or clothes which could
bleach may contaminate the sur-
face 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 main-
tain its quality.
- Wipe the natural leather seat
cover often with dry or soft cloth.
- Use of a 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 protec-
tive agents.
- Light colored(beige, 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.

Maintenance
• Cleaning the leather seats
- Remove all contaminations
instantly. Refer to instructions
below for removal of each con-
taminant.
- 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 contami-
nations do not smear.
- Oil
Remove oil instantly with
absorbable cloth and wipe with
stain remover used only for natu-
ral leather.
- Chewing gum
Harden the gum with ice and
remove gradually.
• Handling prime napa leather
(if equipped)
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, imme-
diately 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 contaminat-
ed or stained from dyed materials
such as jeans.
Interior wooden trim
• Use a wooden furniture protector
(e.g. wax, coating compound) to
clean the interior wooden trim.
• Often wipe the interior wooden trim
with a lint-free, clean cloth to main-
tain the unique wooden textures for
a longer period of time.
• If you spill beverage (e.g. water,
coffee) over the interior wooden
trim, immediately wipe it with
clean, dry cloth.
• Sharp objects (e.g. driver, knife),
adhesive materials, or tapes
may damage the interior wooden
trim.
• Any strong impacts may dam-
age 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 immedi-
ately 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, cov-
ered with an oily, greasy or waxy
film), they should be cleaned with
glass cleaner. Follow the directions
on the glass cleaner container.
Do not scrape or scratch the
inside of the rear window. This
may result in damage to the rear
window defroster grid.

Maintenance
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 sys-
tem
(2) Evaporative emission control sys-
tem
(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.
For the Inspection and Maintenance
Test (
with Electronic Stability Control
system)
• To prevent the vehicle from mis-
firing during dynamometer test-
ing, turn the Electronic Stability
Control 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 atmos-
phere. The ORVR system is
designed to allow the vapors from
the fuel tank to be loaded into a can-
ister while refueling at the gas sta-
tion, 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 sole-
noid valve.

Purge Control Solenoid Valve
(PCSV)
The purge control solenoid valve is
controlled by the Engine Control
Module; 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.
3. Exhaust Emission Control
System
The Exhaust Emission Control
System is a highly effective system
which controls exhaust emissions
while maintaining good vehicle per-
formance.
When the engine starts or fails to
start, excessive attempts to restart
the engine may cause damage to the
emission system.
Engine exhaust (carbon monox-
ide) 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 win-
dows fully open. Have your vehicle
checked and repaired immediately.• Do not operate the engine in con-
fined 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. 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 poi-
soning.

Operating precautions for cat-
alytic converters (if equipped)Your vehicle is equipped with a cat-
alytic converter emission control
device. To prevent damage to the
catalytic converter and to your vehi-
cle, take the following precautions:
• Use only UNLEADED FUEL for
gasoline engines.
• Do not operate the vehicle when
there are signs of engine malfunc-
tion, such as misfire or a noticeable
loss of performance.
• Do not misuse or abuse the
engine. Examples of misuse are
coasting with the engine off and
descending steep grades in gear
with the engine off.
• Do not operate the engine at high
idle speed for extended periods (5
minutes or more).
• Do not modify or tamper with any
part of the engine or emission con-
trol system. All inspections and
adjustments must be made by an
authorized retailer of Genesis
Branded products.
• Avoid driving with extremely low
fuel level. If you run out of gasoline,
it could cause the engine to misfire
and result in excessive loading of
the catalytic converter. The exhaust system and cat-
alytic converter are very hot
during and immediately after
the engine has been running. To
avoid SERIOUS INJURY or
DEATH:
• Do not park, idle, or drive the
vehicle over or near flamma-
ble objects, such as grass,
vegetation, paper, leaves, etc.
A hot exhaust system can
ignite flammable items under
your vehicle.
• Keep away from the exhaust
system and catalytic convert-
er or you may get burned.
Also, Do not remove the heat
sink around the exhaust sys-
tem, do not seal the bottom of
the vehicle, and do not coat
the vehicle for corrosion con-
trol. It may present a fire risk
under certain conditions.
