Corrosion protection
Protecting your vehicle from corro-
sion
By using the most advanced design
and construction practices to combat
corrosion, we produces cars of the
highest quality. However, this is only
part of the job. To achieve the long-
term corrosion resistance your vehi-
cle can deliver, the owner's coopera-
tion and assistance is also required.
Common causes of corrosion
The most common causes of corro-
sion on your car are:
Road salt, dirt and moisture that isallowed to accumulate underneath
the car.
Removal of paint or protective coat- ings by stones, gravel, abrasion or
minor scrapes and dents which
leave unprotected metal exposed to
corrosion.
High-corrosion areas
If you live in an area where your car
is regularly exposed to corrosive
materials, corrosion protection is
particularly important. Some of the
common causes of accelerated cor-
rosion 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
temperatures are just above freezing.
In such conditions, the corrosive
material is kept in contact with the car
surfaces by moisture 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 cor-
rosion. 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 car clean and free of mud
or accumulations of other materials.
This applies not only to the visible sur-
faces but particularly to the underside
of the car.To help prevent corrosion
You can help prevent corrosion from
getting started by observing the fol-

Maintenance
Keep your car clean
The best way to prevent corrosion is
to keep your car clean and free of
corrosive materials. Attention to the
underside of the car 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 car at least once
a month and be sure to clean the
underside thoroughly when winter
is over.
When cleaning underneath the car, give particular attention to the
components under the fenders and
other areas that are hidden from
view. Do a thorough job; just damp-
ening the accumulated mud rather
than washing it away will acceler-
ate 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 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 car in the garage or drive it into
the garage when it is still wet or cov-
ered with snow, ice or mud. Even a
heated garage can contribute to cor-
rosion 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 atten-
tion 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 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 car.
These should be carried only in
proper containers and any spills or
leaks should be cleaned up, flushed
with clean water and thoroughly
dried.

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 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 accor-
dance 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 con-trol system
The Evaporative Emission Control
System is designed to prevent fuel
vapors from escaping into the atmos-
phere.
For the Inspection and Maintenance
Test (With Electronic Stability Control
(ESC) system)
To prevent the vehicle from
misfiring during dynamome-
ter testing, turn the Electronic
Stability Control (ESC) sys-
tem off by pressing the ESC
switch.
After dynamometer testing is
completed, turn the ESC sys-
tem back on by pressing the
ESC switch again.
CAUTION

Maintenance
Do not modify or tamper with any part of the engine or emission con-
trol system. All inspections and
adjustments must be made by an
authorized HYUNDAI dealer.
Avoid driving with a very low fuel level. If you run out of gasoline, it
could cause the engine to misfire
and result in excessive loading of
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.
The DPF system automatically burns
(or oxidizes) the accumulated soot in
accordance with the driving situa-
tions, unlike a disposable air filter.
In other words, the accumulated soot
is automatically purged out by the
engine control system and by the high
exhaust-gas temperature at normal/
high driving speeds.
However, when the vehicle is continu-
ally 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. In this case,
the accumulated soot is out of the
detection range, the soot oxidization
process does not occur, and the
Malfunction Indicator Lamp ( )
Illuminates. The Malfunction Indicator Lamp (MIL)
stops illuminating, when the driving
speed exceeds 60 km/h (37mph), or
when the engine rpm is between
1,500 and 2,500 with the gear in the
2nd position or above for approxi-
mately 25 minutes.
When the MIL continuously blinks or
the warning message “Check exhaust
system” illuminates in the above
cases, we recommend you to have the
DPF system checked by an author-
ized HYUNDAI dealer.
When the vehicle is continuously driv-
en with the MIL flashing for an extend-
ed period of time, it may damage the
DPF system and lower the fuel econ-
omy.
