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
ORG3090046
• 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
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 (e.g. 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.
Waxing
A good coat of wax is a barrier between
your paint and contamination. Keeping
a good coat of wax on your vehicle will
help protect it.
Wax the vehicle until water will no longer
bead on the paint.
Always wash and dry the vehicle before
waxing. Use a good quality liquid or
paste wax, and follow the manufacturer’s
instructions. Wax all metal trim to protect
it and to maintain its luster.
Removing oil, tar, and similar materials
with a spot remover will usually strip the
wax from the finish. Be sure to re-wax
these areas even if the rest of the vehicle
does not yet need waxing.

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.

To help prevent corrosion
Keep your vehicle clean
The best 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.

Leather
• 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 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 (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.
• 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.

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.

Operating precautions for catalytic
converters
WARNING
The exhaust system and catalytic
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 flammable 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 converter or you may
get burned.
Also, do not remove the heat sink
around the exhaust system, do not
seal the bottom of the vehicle, and
do not coat the vehicle for corrosion
control. It may present a fire risk
under certain conditions.
Your vehicle is equipped with a catalytic
converter emission control device.
To prevent damage to the catalytic
converter and to your vehicle, take the
following precautions:
• Use only UNLEADED FUEL for
gasoline engines.
• Do not operate the vehicle when
there are signs of engine malfunction,
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
control system. All inspections and
adjustments must be made by an
authorized retailer of Genesis Branded
products.
• Avoid driving with an extremely low
fuel level.
Running out of fuel could cause the
engine to misfire, damaging the
catalytic converter.
