Corrosion protection
Protecting your vehicle from corro-
sion
By using the most advanced design and
construction practices to combat corro-
sion, HYUNDAI produces cars of the
highest quality. However, this is only part
of the job. To achieve the long-term cor-
rosion resistance your vehicle can deliv-
er, the owner’s cooperation and assis-
tance is also required.
Common causes of corrosion
The most common causes of corrosion
on your vehicle are:
Road salt, dirt and moisture that isallowed to accumulate underneath the
vehicle.
Removal of paint or protective coatings by stones, gravel, abrasion or minor
scrapes and dents which leave unpro-
tected metal exposed to corrosion.
High-corrosion areas
If you live in an area where your vehicle
is regularly exposed to corrosive materi-
als, 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
corrosion is most likely to occur. For
example, corrosion is accelerated by
high humidity, particularly when tempera-
tures are just above freezing. In such
conditions, the corrosive material is kept
in contact with the car surfaces by mois-
ture 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 the
moisture and promote corrosion.
High temperatures can also accelerate
corrosion of parts that are not properly
ventilated so the moisture can be dis-
persed. For all these reasons, it is partic-
ularly 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.
To help prevent corrosion
Keep your car clean
The best way to prevent corrosion is to
keep your vehicle clean and free of corro-
sive 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 compo-
nents under the fenders and other
areas that are hidden from view. Do a
thorough job; just dampening the accu-
mulated mud rather than washing it
away will accelerate corrosion rather
than prevent it. Water under high pres-
sure and steam are particularly effec-
tive 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.

Maintenance
Keep your garage dry
Don’t park your car in a damp, poorly
ventilated garage. This creates a favor-
able 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 cor-
rosion. 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.
Interior Care
Interior general precautions
Prevent caustic solutions such as per-
fume 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 vinyl.
Never allow water or other liquids tocome in contact with electrical/elec-
tronic components inside the vehi-
cle as this may damage them.
When cleaning leather products (steering wheel, seats etc.), use neu-
tral detergents or low alcohol con-
tent solutions. If you use high alco-
hol content solutions or acid/ alka-
line detergents, the color of the
leather may fade or the surface may
get stripped off.
Cleaning the upholstery andinterior trim
Vinyl (if equipped)
Remove dust and loose dirt from vinyl
with a whisk broom or vacuum cleaner.
Clean vinyl surfaces with a vinyl cleaner.
Fabric (if equipped)
Remove dust and loose dirt from fabric
with a whisk broom or vacuum cleaner.
Clean with a mild soap solution recom-
mended 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.
Using anything but recommended
cleaners and procedures may affect
the fabric's appearance and fire-
resistant properties.

Maintenance
Leather (if equipped)
Feature of Seat Leather- Leather is made from the outer skinof an animal, which goes through a
special process to be available for
use. Since it is a natural object, 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. Caring for the leather seats
- Vacuum the seat periodically toremove 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 protective 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.
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 fab-
ric.
Make sure not to wet the seat. It
may change the nature of natural
leather.
Jeans or clothes which could
bleach may contaminate the sur-
face of the seat covering fabric.
CAUTION

Maintenance
Cleaning the leather seats- Remove all contaminations instantly.Refer to instructions below for
removal of each contaminant.
- Cosmetic products (sunscreen, foun- dation, etc.)
Apply cleansing cream on a cloth and
wipe the contaminate 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 contamina-
tions 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.Cleaning the seat belt webbing
Clean the belt webbing with any mild
soap solution recommended for cleaning
upholstery or carpet. Follow the instruc-
tions provided with the soap. Do not
bleach or re-dye the webbing because
this may weaken the seat belt.
Cleaning the interior windowglass
If the interior glass surfaces of the vehi-
cle 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.
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 infor-
mation contained in the Owner’s
Handbook & Warranty Information book-
let in your vehicle.
Your vehicle is equipped with an emis-
sion 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 assure the proper function of
the emission control systems, it is recom-
mended that you have your vehicle
inspected and maintained by an author-
ized HYUNDAI dealer in accordance with
the maintenance schedule in this manual.For the Inspection and Maintenance
Test (With Electronic Stability Control
(ESC) system)
To prevent the vehicle from misfir-
ing during dynamometer testing,
turn the Electronic Stability Control
(ESC) system off by pressing the
ESC switch (ESC OFF light illumi-
nated).
After dynamometer testing is com- pleted, turn the ESC system back on
by pressing the ESC switch again.1. Crankcase Emission Control System
The positive crankcase ventilation sys-
tem 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 ControlSystem 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 canister while refueling at
the gas station, preventing the escape of
fuel vapors into the atmosphere.

Maintenance
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 con-
trolled by the Engine Control Module
(ECM); when the engine coolant temper-
ature is low during idling, the PCSV clos-
es 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 performance.
When the engine starts or fails to start,
excessive attempts to restart the engine
may cause damage to the emission sys-
tem.
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 vehi-
cle, drive with all the windows fully
open. Have your vehicle checked and
repaired immediately.
Engine exhaust gases contain car-
bon monoxide (CO). Though color-
less 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 vehi-
cle, contain or emit chemicals
known to the State of California to
cause cancer and birth defects and
reproductive harm. In addition, cer-
tain 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.

Maintenance
Do not operate the engine in confinedor 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 vehi- cle 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.Operating precautions for cat-alytic converters (if equipped)
Your vehicle is equipped with a catalytic
converter emission control device.
To prevent damage to the catalytic con-
verter and to your vehicle, take the fol-
lowing precautions: 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, vegeta-
tion, paper, leaves, etc. A hot
exhaust system can ignite flam-
mable items under your vehicle.
Keep away from the exhaust sys-
tem 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 vehi-
cle, and do not coat the vehicle
for corrosion control. It may pres-
ent a fire risk under certain con-
ditions.
WARNING Use only UNLEADED FUEL for
gasoline engines.
Do not operate the vehicle when
there are signs of engine mal-
function, 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 HYUNDAI deal-
er.
Avoid driving with extremely low
fuel level. If you run out of gaso-
line, it could cause the engine to
misfire and result in excessive
loading of the catalytic converter.
