Maintenance
High temperatures can also acceler-
ate corrosion of parts that are not
properly ventilated so the moisture
can be dispersed. For all these rea-
sons, it is particularly important to
keep your vehicle clean and free of
mud or accumulations of other mate-
rials. This applies not only to the vis-
ible surfaces but particularly to the
underside of the vehicle.
To help prevent corrosion
You can help prevent corrosion from
getting started by observing the fol-
lowing:
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 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, give 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 mem-
bers, 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 cre-
ates a favorable environment for cor-
rosion. 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 con-
tribute to corrosion unless it is well
ventilated so moisture is dispersed.

Maintenance
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 : 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 to cause corro-
sion. Check under the mats periodi-
cally to be sure the carpeting is dry.
Use particular care if you carry fertil-
izers, cleaning materials or chemi-
cals 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 clean-
er, 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.Never allow water or other liq-uids to come in contact with
electrical/electronic compo-
nents inside the vehicle as this
may damage them.
CAUTION

Maintenance
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.
Cleaning the lap/shoulder beltwebbing
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 weakenit.
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.
Using anything but recom-
mended cleaners and proce-
dures may affect the fabric’sappearance and fire-resistant
properties.
CAUTION
When cleaning leather products
(steering wheel, seats etc.), use
neutral detergents or low alco-
hol content solutions. If you usehigh alcohol content solutions
or acid/alkaline detergents, the
color of the leather may fade or
the surface may get stripped
off.
CAUTION
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 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 orother repair shops that use qualifiedtechnicians in accordance with the
maintenance schedule in this manu-al.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 con-trol System
The Evaporative Emission Control
System is designed to prevent fuel
vapors from escaping into the atmos-
phere.
Canister
Fuel vapors generated inside the fueltank 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.
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 perform-
ance 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 vehi-
cle, 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. 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.
Exhaust
Engine exhaust gases contain
carbon monoxide (CO). Though
colorless and odorless, it is
dangerous and could be lethal if
inhaled. Follow the instructions
following to avoid CO poison-ing.

Maintenance
Operating precautions for cat-alytic converters (if equipped)Your vehicle is equipped with a cat-
alytic converter emission control
device.
Therefore, the following precautions
must be observed:
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 arecoasting 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 con-
trol system. We recommend that
the system be inspected by an
authorized HYUNDAI dealer.
Avoid driving with a extremely low fuel level. Running out of fuel
cause the engine to misfire, dam-
aging the catalytic converter. Failure to observe these precautionscould result in damage to the catalyt-
ic converter and to your vehicle.
Additionally, such actions could void
your warranties.
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 dry grass, paper,
leaves, etc.
The exhaust system and cat-
alytic system are very hotwhile the engine is running or
immediately after the engine
is turned off. Keep away from
the exhaust system and cat-
alytic, you may get burned.
Also, do not remove the heat
sink around the exhaust sys-
tem, 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.

Maintenance
Diesel Particulate Filter (if equipped)
The Diesel Particulate Filter (DPF)
system removes the soot emitted
from the vehicle.
Unlike a disposable air filter, the DPF
system automatically burns (oxi-
dizes) and removes the accumulated
soot according to the driving condi-
tion. In other words, the active burn-
ing by engine control system and
high exhaust gas temperature
caused by normal/high driving condi-
tion burns and removes the accumu-lated soot.
However, if the vehicle continues to
be driven in short distance repeated-
ly or at low speed for a long time, the
accumulated soot may not be auto-
matically removed because of low
exhaust gas temperature. In this par-
ticular case, if the amount of soot is
out of detection limit, the DPF warn-
ing indicator ( ) will illuminate. In order to start the DPF regenera-
tion and to stop the DPF warning
lamp illuminating, drive the vehicle in
a safety driving circumstance with
more than 60km/h (37 mph) vehiclespeed or with more than secondgear engaged and 1500 ~ 2000
engine rpm for a certain time (for
about 25 minutes).
If the DPF warning indicator( )
continues to blink or "check emissionsystem" message comes on in the
cluster in spite of the above proce-
dure, we recommend that the system
be checked by an authorized
HYUNDAI dealer.
If you continue to drive with the indi-
cator light blinking for a long time, theDPF system can be damaged and
fuel consumption can be worsen.Diesel Fuel (if equipped with DPF) It is recommended to use the regulated automotive diesel
fuel for diesel vehicle equippedwith the DPF system.
If you use diesel fuel including high sulfur (more than 50 ppm
sulfur) and unspecified addi-
tives, it can cause the DPF sys-
tem to be damaged and whitesmoke can be emitted.
