Corrosion protection
Protecting your vehicle from corrosion
By using the most advanced design
and cons
truction practices to combat
corrosion, HYUNDAI produces vehicles
of the highest quality. However, this is
only part of the job. To achieve the long-
term corrosion resistance your vehicle
can deliver, the owner’s cooperation and
assistance is also required.
Common causes of corrosion
The most common causes of corrosion
on y
our vehicle are:

[ Road salt, dirt and moisture that is
allowed to accumulate underneath
the vehicle.

[ Removal of paint or protective
coatings 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 vehicle is
r
egularly exposed to corrosive materials,
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 corr

osion 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 corrosion.
High temperatures can also accelerate
corrosion of parts that are not properly
ventilated so the moisture can be
dispersed. For all these reasons, it is
particularly 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.

Interior Care
Interior general precautions
Prevent caustic solutions such as
perfume 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
vehicle interior surfaces.
NOTICE

[ Never allow water or other liquids
to come in contact with electrical/
electronic components inside the
vehicle as this may damage them.

[ 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
Vehicle interior surfaces (if equipped)
Remove dust and loose dirt from interior
surf

aces with a whisk broom or a vacuum
cleaner.
If necessary, clean interior surfaces with
a mixture of warm water and mild non-
detergent cleaner (test all cleaners on a
concealed area before use).
Fabric (if equipped)
Remove dust and loose dirt from
f
abric 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.

Maintenance9-72
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 weaken the seat belt.
Cleaning the interior window glass
If the interior glass surfaces of the
vehicle become hazy (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.

The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty
information contained in the Owner’s
Handbook & Warranty Information
booklet 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 system
(2) Evaporative emission control system
(3) Exhaust emission control system
In order to ensure the proper function
of the emission control systems, have
your vehicle inspected and maintained
by an authorized HYUNDAI dealer in
accordance with the maintenance
schedule in this manual.
NOTICE
For the Inspection and Maintenance
Test (with Electronic Stability Control
(ESC) system)

[To prevent the vehicle from misfiring
during dynamometer testing, turn
the Electronic Stability Control
(ESC) system off by pressing the ESC
switch (ESC OFF light illuminated).

[ After dynamometer testing is
completed, turn the ESC system back
on by pressing the ESC switch again.
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 Including Onboard
Refueling Vapor Recovery
(ORVR)
The Evaporative Emission Control System
is designed to prevent fuel vapors from
escaping into the atmosphere. 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.
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.
EMISSION CONTROL SYSTEM

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
system.
Engine exhaust (carbon monoxide)
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 windows
fully open. Have your vehicle checked
and repaired immediately.
WARNING
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.
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 vehicle, contain
or emit chemicals known to the State
of California to cause cancer and
birth defects and reproductive harm.
In addition, certain 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.
[
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.
