Maintenance
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, give 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 : Bird droppings are
highly corrosive and may damage
painted surfaces in just a few hours.
Always remove bird droppings as soon
as possible.
Don’t neglect the interior
Moisture can collect under the floor
mats and carpeting and cause corrosion.
Check under the mats periodically to be
sure the carpeting is dry. Use particular
care if you carry fertilizers, cleaning
materials or chemicals in the vehicle.
These should be carried only in proper
containers and any spills or leaks should
be cleaned up, flushed with clean water
and thoroughly dried.

Interior care
Interior general precautions
Prevent chemicals such as perfume,
cosmetic oil, sun cream, hand cleaner,
and air freshener 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 that
follow for the proper way to clean vinyl.
NOTICE
Never allow water or other liquids
to come in contact with electrical/
electronic components inside the
vehicle as this may damage them.
NOTICE
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
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
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.

Maintenance
Leather (if equipped)
• Feature 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 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.
CAUTION
• 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 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.

• 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 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
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. Cleaning the lap/shoulder 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 it.
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.

Maintenance
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
emission regulations.
There are three emission control systems
which are 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 recommended that you have your
car inspected and maintained by
an authorized HYUNDAI dealer in
accordance 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 control
system
The Evaporative Emission Control
System is designed to prevent
fuel vapors from escaping 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.

3. Exhaust emission control
system
The Exhaust Emission Control System is
a highly effective system which controls
exhaust emissions while maintaining
good vehicle performance.
Vehicle modifications
• This vehicle should not be modified.
Modification of your vehicle could
affect its performance, safety or
durability and may even violate
governmental safety and emissions
regulations.
In addition, damage or performance
problems resulting from any
modification 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 gas precautions
(carbon monoxide)
• Carbon monoxide can be present with
other exhaust fumes. Therefore, if
you smell exhaust fumes of any kind
inside your vehicle, have it inspected
and repaired immediately. If you ever
suspect exhaust fumes are coming
into your vehicle, drive it only with
all the windows fully open. Have
your vehicle checked and repaired
immediately.
WARNING
Exhaust
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.
• 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.

Maintenance
Operating precautions for catalytic
converters (if equipped)
WARNING
Fire
• A hot exhaust system can ignite
flammable items under your vehicle.
Do not park, idle, or drive the vehicle
over or near flammable objects, such
as grass, vegetation, paper, leaves,
etc.
• The exhaust system and catalytic
system are very hot while the engine
is running or immediately after the
engine is turned off. Keep away from
the exhaust system and catalytic, you
may get burned. Also, do not remove
the heat sink around the exhaust
system, do not seal the bottom of the
vehicle or 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.
Therefore, the following precautions
must be observed:
• Use only UNLEADED FUEL for petrol
engine.
• 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 ignition off and descending steep
grades in gear with the ignition 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 dealer.
• Avoid driving with a extremely low fuel
level. Running out of fuel could cause
the engine to misfire, damaging the
catalytic converter.
Failure to observe these precautions
could result in damage to the catalytic
converter and to your vehicle.
Additionally, such actions could void
your warranties.

Diesel particulate filter (DPF)
(if equipped)
The Diesel Particulate Filter (DPF)
system removes the soot in the exhaust
gas. Unlike a disposable air filter,
the DPF system automatically burns
(oxidizes) and removes the accumulated
soot according to the driving condition.
In order words, the active burning by
engine control system and high exhaust
gas temperature caused by normal/high
diving condition burns and removes the
accumulated soot.
However, if the vehicle continues to
be driven at repeated short distance
or driven at low speed for a long time,
the accumulated soot may not be
automatically removed because of low
exhaust gas temperature. More than
a certain amount of soot deposited,
the malfunction indicator light (
)
illuminates.
When the malfunction indicator light
illuminates, it may turn-off after driving
the vehicle at more than 60km/h (37
mph) or at more than second gear with
1500~2500 engine rpm for a certain time
(for about 25 minutes).
If the malfunction indicator light (
) is not turn-off or blinking continuesly
in spite of the procedure, visit a
professional workshop and check the
DPF system. HYUNDAI recommends
to visit an authorized HYUNDAI dealer/
service partner.
If you continue to drive with the
malfunction indicator light blinking for
a long time, the DPF system can be
damaged and fuel consumption can be
worsen and the engine durability can be
worsen by oil dilution.
CAUTION
Diesel Fuel (if equipped with DPF)
We recommend you to use only the
regulated diesel fuels, when your
vehicle is equipped with the DPF
system.
When you use other diesel fuels, which
is high in sulfurs (above 50 ppm) or
contains unspecified additives, it may
damage the DPF system and cause the
white smoke emission.
Lean NOx Trap (if equipped)
The Lean NOx Trap (LNT) system
removes the nitrogen oxide in the
exhaust gas. The smell can occur in the
exhaust gas depending on the quality
of the fuel and it can degrade NOx
reduction performance, please use the
regulated automotive diesel fuel.
