To help prevent corrosion
Keep your car 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 partic-
ularly 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 leastonce a month and be sure to cleanthe underside thoroughly when
winter is over.
vehicle, pay particular attention to
the components under the fendersand 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 pres-
sure 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 keptopen so that moisture can escape
and not be trapped inside to accel-
erate corrosion.
Keep your garage dry
Don’t park your car in a damp, poor-
ly 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 ventilatedso 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 atten-tion of a qualified body and paintshop 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.

Maintenance
Interior care
Interior general precautions
Prevent caustic solutions such as perfume and cosmetic oil, from con-
tacting the interior parts because
they may cause damage or discol-
oration. If they do contact the interior
parts, wipe them off immediately.
See the instructions for the proper
way to clean vinyl.
Cleaning the upholstery andinterior trim
Vinyl
Remove dust and loose dirt from
vinyl with a whisk broom or vacuum
cleaner. Clean vinyl surfaces with a
vinyl cleaner.
Fabric
Remove dust and loose dirt from fab-
ric with a whisk broom or vacuum
cleaner. Clean with a mild soap solu-
tion recommended for upholstery or
carpets. Remove fresh spots imme-
diately 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 proper-ly maintained.
Leather (if equipped)
Feature of Seat Leather
- Leather is made from the outerskin of an animal, which goes through a special process to be
available for use. Since it is a nat-
ural 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 driv-
ing comfort and stability.
- Wrinkles may appear naturally from usage. It is not a fault of the
products.
Using anything but recom-
mended cleaners and proce-
dures may affect the fabric’sappearance and fire-resistant
properties.
CAUTION
Never allow water or other liq- uids to come in contact with
electrical/electronic compo-
nents inside the vehicle as
this may damage them.
When cleaning leather prod-
ucts (steering wheel, seats
etc.), use neutral detergents
or low alcohol content solu-
tions. If you use high alcoholcontent solutions or acid/
alkaline detergents, the color
of the leather may fade or the
surface may get stripped off.

Maintenance
Caring for the leather seats- Vacuum the seat periodically toremove dust and sand on the
seat. It will prevent abrasion ordamage of the leather and main-
tain 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 instruc-tions and consult a specialistwhen using leather coating or
protective agent.
- Light colored (beige, cream beige) leather is easily contami-
nated 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 contaminationsinstantly. Refer to instructions
below for removal of each con-taminant.
- Cosmetic products (sunscreen, foundation, etc.)
Apply cleansing cream on a clothand wipe the contaminate spot.
Wipe off the cream with a wet
cloth and remove water with a drycloth.
- Beverages (coffee, soft drink, etc.)
Apply a small amount of neutraldetergent 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.
Wrinkles or abrasions which
appear naturally from usage
are not covered by warranty.
Belts with metallic acces-
sories, zippers or keys inside
the back pocket may damagethe 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 coveringfabric.

Maintenance
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 weakenthe seat belt.
Cleaning the interior windowglass
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
EEMM IISS SSIIOO NN CC OO NNTTRR OO LL SS YY SSTT EEMM
The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty
information contained in the Service
Passport 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 systemIn order to assure the proper function
of the emission control systems, it is
recommended that you have your
vehicle inspected and maintained by
an authorized HYUNDAI dealer inaccordance with the maintenance
schedule in this manual.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 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 fromthe 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.
For the Inspection and
Maintenance Test (With Electronic
Stability Control (ESC) system)
To prevent the vehicle from
ESC acitvation during
dynamometer testing, turn the
Electronic Stability Control
(ESC) system off by pressing
the ESC switch (ESC OFFlight illuminated).
After dynamometer testing is
completed, turn the ESC sys-
tem back on by pressing the
ESC switch again.

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 surgetank through the purge control sole-
noid 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 evap-
orated 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 theemission system.
Vehicle modifications
This vehicle should not be modi-fied. Modification of your vehicle
could affect its performance, safety
or durability and may even violate
governmental safety and emis-
sions regulations.
In addition, damage or performance
problems resulting from any modifi-
cation may not be covered under
warranty.
If you use unauthorized electronic devices, it may cause the vehicle to
operate abnormally, wire damage,
battery discharge and fire. For your
safety, do not use unauthorized
electronic devices.
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.
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.

Maintenance
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 orout 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 tothe emission control system.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 vehicle, take
the following precautions:
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.

engine. Examples of misuse
are coasting with the hybridsystem 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). (Continued)
CAUTION(Continued)
Do not modify or tamper with
any part of the engine or
emission control system. Allinspections and adjustments
must be made by an author-
ized HYUNDAI dealer.
Avoid driving with extremely
low fuel level. If you run out of
gasoline, it could cause theengine to misfire and result in
excessive loading of the cat-
alytic converter.
