Maintenance
High-pressure washing
When using high-pressure washers,
make sure to maintain sufficient dis-
tance from the vehicle.
Insufficient clearance or excessive
pressure can lead to component
damage or water penetration.
Do not spray the camera, sensors or
its surrounding area directly with a
high pressure washer. Shock
applied from high pressure water
may cause the device to not operate
normally.
Do not bring the nozzle tip close to
boots (rubber or plastic covers) or
connectors as they may be dam-
aged if they come into contact with
high pressure water. Water washing in the engine com-
partment including high pressure
water washing may cause the fail-
ure of electrical circuits located in
the engine compartment.
Never allow water or other liquids
to come in contact with electri-
cal/electronic components inside
the vehicle as this may damage
them.Matte paint finish vehicle
Automatic car wash which uses
rotating brushes should not be
used as this can damage the sur-
face of your vehicle. A steam
cleaner which washes the vehicle
surface at high temperature may
result the oil to adhere and leave
stains that is difficult to remove.
Use a soft cloth (e.g. microfiber
towel or sponge) when washing
your vehicle and dry with a
microfiber towel. When you hand
wash your vehicle, you should not
use a cleaner that finishes with
wax. If the vehicle surface is too
dirty (sand, dirt, dust, contami-
nant, etc.), clean the surface with
water before washing the vehicle.

Waxing
A good coat of wax is a barrier
between your paint and contami-
nants. Keeping a good coat of wax
on your vehicle will help protect it.
Wax the vehicle when water will no
longer bead on the paint.
Always wash and dry the vehicle
before waxing. Use a good quality
liquid or paste wax, and follow the
manufacturer’s instructions. Wax all
metal trim to protect it and to main-
tain its luster.
Removing oil, tar, and similar materi-
als with a spot remover will usually
strip the wax from the finish. Be sure
to re-wax these areas even if the rest
of the vehicle does not yet need wax-
ing. Wiping dust or dirt off the body
with a dry cloth will scratch the
finish.
Do not use steel wool, abrasive
cleaners, or strong detergents
containing highly alkaline or
caustic agents on chrome-plated
or anodised aluminium parts.
This may result in damage to the
protective coating and cause dis-
colouration or paint deteriora-
tion.
Matte paint finish vehicle
Do not use any polish protector
such as a detergent, an abrasive
and a polish. In case wax is
applied, remove the wax immedi-
ately using a silicon remover and
if any tar or tar contaminant is on
the surface use a tar remover to
clean. However, be careful not to
apply too much pressure on the
painted area.
Finish damage repair
Deep scratches or stone chips in the
painted surface must be repaired
promptly. Exposed metal will quickly
rust and may develop into a major
repair expense.
If your vehicle is damaged and
requires any metal repair or
replacement, be sure the body
shop applies anti-corrosion materi-
als to the parts repaired or replaced.
Matte paint finish vehicle
In case of matte paint finish vehi-
cles, it is impossible to modify only
the damaged area and repair of the
whole part is necessary. If the vehi-
cle is damaged and painting is
required, we recommend that you
have your vehicle maintained and
repaired by an authorised
HYUNDAI dealer. Take extreme
care, as it is difficult to restore the
quality after the repair.

Bright-metal maintenance
To remove road tar and insects,
use a tar remover, not a scraper or
other sharp object.
To protect the surfaces of bright-
metal parts from corrosion, apply a
coating of wax or chrome preser-
vative and rub to a high luster.
During winter weather or in coastal
areas, cover the bright metal parts
with a heavier coating of wax or
preservative. If necessary, coat the
parts with non-corrosive petroleum
jelly or other protective compound.
Underbody maintenance
Corrosive materials used for ice and
snow removal and dust control may
collect on the underbody. If these
materials are not removed, acceler-
ated rusting can occur on underbody
parts such as the fuel lines, frame,
floor pan and exhaust system, even
though they have been treated with
rust protection.
Thoroughly flush the vehicle under-
body and wheel openings with luke-
warm or cold water once a month,
after off-road driving and at the end of
each winter. Pay special attention to
these areas because it is difficult to
see all the mud and dirt. It will do
more harm than good to wet down the
road grime without removing it. The
lower edges of doors, rocker panels,
and frame members have drain holes
that should not be allowed to clog with
dirt; trapped water in these areas can
cause rusting.After washing the vehicle, test
the brakes whilst driving slowly
to see if they have been affected
by water. If braking performance
is impaired, dry the brakes by
applying them lightly whilst
maintaining a slow forward
speed.WARNING

Maintenance
Aluminium wheel maintenance
The aluminium wheels are coated
with a clear protective finish.
Do not use any abrasive cleaner,
polishing compound, solvent,
or wire brushes on aluminium
wheels.
Clean the wheel when it has
cooled.
Use only a mild soap or neutral
detergent, and rinse thoroughly
with water. Also, be sure to clean
the wheels after driving on salted
roads.
Do not wash the wheels with high-
speed car wash brushes.
Do not use any cleanser contain-
ing acid or alkaline detergents.
Corrosion protection
Protecting your vehicle from corro-
sion
By using the most advanced design
and construction practices to combat
corrosion, we 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 corro-
sion on your vehicle are:
Road salt, dirt and moisture that is
allowed to accumulate underneath
the vehicle.
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 vehi-
cle 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
vehicle 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 moisture and promote corro-
sion.
NOTICE

7-82
Maintenance
High temperatures can also acceler-
ate corrosion of parts that are not
properly ventilated so the moisture
can bedispersed. 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 visi-
ble 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 corro-
sion. In winter, hose off the under-
side of your vehicle at least once a
month and be sure to clean the
underside thoroughly when winter
is over.

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 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 kept
open so that moisture can escape
and not be trapped inside, to accel-
erate corrosion.
Keep your garage dry
Don't park your vehicle in a damp,
poorly ventilated garage. This cre-
ates a favourable 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 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 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 fer-
tilisers, 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 discolouration. 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 liquids to
come in contact with electrical/elec-
tronic components inside the vehi-
cle 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 colour of
the leather may fade or the sur-
face 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 recom-
mended 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 colour can
be affected. Also, its fire-resistant prop-
erties can be reduced if the material is
not properly maintained.
Using anything but recommended
cleaners and procedures may affect
the fabric’s appearance and fire-
resistant properties.

Leather (if equipped)
Features 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 nat-
ural product, 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
product. 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 qual-
ity.
- Wipe the natural leather seat cover
often with dry or soft cloth.
- Use of proper leather protector
may prevent abrasion of the cover
and helps maintain the colour. Be
sure to read the instructions and
consult a specialist when using
leather coating or protective agent.
- Light coloured (beige, cream
beige) leather is easily contaminat-
ed and the stain is noticeable.
Clean the seats frequently.
- Avoid wiping with wet cloth. It may
cause the surface to crack.
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 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.

Maintenance
Cleaning the leather seats
- Remove all contaminations instant-
ly. Refer to instructions below for
removal of each contaminant.
- Cosmetic products (sunscreen,
foundation, etc.)
Apply cleansing cream on a cloth
and wipe the contaminated 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 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.Cleaning the lap/shoulder belt
webbing
Clean the belt webbing with any mild
soap solution recommended for clean-
ing 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, 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.

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
Australian Design Rules (ADR)
requirements.
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 ensure the proper function
of the emission control systems, it is
recommended that you have your
vehicle inspected and maintained by
an authorised HYUNDAI dealer in
accordance with the maintenance
schedule in this manual.For the Inspection and Maintenance
Test (with Electronic Stability
Control (ESC) system)
To prevent the vehicle from mis-
firing during dynamometer test-
ing, turn the Electronic Stability
Control (ESC) system off by
pressing the ESC switch.
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 con-
trol system
The Evaporative Emission Control
System is designed to prevent fuel
vapours from escaping into the
atmosphere.

Maintenance
Canister
Fuel vapours generated inside the
fuel tank are absorbed and stored in
the onboard canister. When the
engine is running, the fuel vapours
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 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 con-
trols exhaust emissions whilst main-
taining good vehicle performance.
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. 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 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.
Engine exhaust gases contain
carbon monoxide (CO). Though
colourless and odourless, it is
dangerous and could be lethal if
inhaled. Follow the instructions
following to avoid CO poisoning.
