Maintenance
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
Road salt and other corrosive chemi-
cals are used in cold weather states to
melt snow and prevent ice accumula-
tion. If these chemicals are not regu-
larly removed, they will corrode the
vehicle underbody and over time dam-
age fuel lines, the fuel tank retention
system, the vehicle suspension, the
exhaust system, and even the body
frame.
Wash the undercarriage of your
vehicle regularly during the winter
and whenever your vehicle has
been exposed to such salts or
chemicals.
Do a thorough washing of the
undercarriage at the end of the
winter.
Use professional service techni-
cians or governmental inspection
stations to annually inspect for cor-
rosion. Immediately seek an inspection of
your vehicle if you become visually
aware of corrosion flaking or scal-
ing or if you become aware of a
change in vehicle performance,
such as soft or spongey brakes,
fluids leaking, impairment of direc-
tional control, suspension noises
or rattling metal straps.

Aluminum wheel maintenance
The aluminum wheels are coated with
a clear protective finish.
Do not use any abrasive cleaner,
polishing compound, solvent, or wire
brushes on aluminum wheels. They
may scratch the finish.
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.
This helps prevent corrosion.
Avoid washing the wheels with high-
speed vehicle wash brushes.
Do not use any alkaline or acid
detergents It may damage and cor-
rode the aluminum wheels coated
with a clear protective finish.
Corrosion protection
Protecting your vehicle from corrosion
By using the most advanced design
and construction practices to combat
corrosion, we produce 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
coatings by stones, gravel, abra-
sion or minor scrapes and dents
which leave unprotected metal
exposed to corrosion.WARNING
After washing the vehicle, test
the brakes while driving slowly
to see if they have been affected
by water. If braking performance
is impaired, dry the brakes by
applying them lightly while
maintaining a slow forward
speed.

Maintenance
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, partic-
ularly when temperatures are just
above freezing. In such conditions,
the corrosive material is kept in con-
tact with the vehicle’s surface by
moisture that evaporates slowly.
Mud is particularly corrosive
because it dries slowly 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 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
beginning by observing the following: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 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 pres-
sure and steam are particularly
effective in removing accumulated
mud and corrosive materials.

Maintenance
110 7
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 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.Keep paint and trim in good con-
dition
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 and 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 prop-
er 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. If neces-
sary, use a vinyl cleaner, see product
instructions for correct usage.

Maintenance
Taking care of 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.
Sufficient use of a leather protec-
tive 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
agents.
Leather with bright colors(beige,
cream beige) is easily contaminat-
ed and clear in appearance. Clean
the seats frequently.
Avoid wiping with wet cloth. It may
cause the surface to crack.
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 point.
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 for natural leather
only.
Chewing gum
- Harden the gum with ice and
remove gradually.CAUTION - Electrical
components
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 - Leather
When cleaning leather products
(steering wheel, seats etc.), use
neutral detergents or low alco-
hol 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.

Fabric seat cover using precau-
tions (If equipped)
Please clean the fabric seats regu-
larly with a vacuum cleaner in con-
sideration of fabric material charac-
teristics. If they are heavily soiled
with beverage stains, etc., use a suit-
able interior cleaner. To prevent dam-
age to seat covers, wipe off the seat
covers down to the seams with a
large wiping motion and moderate
pressure using a soft sponge or
microfiber cloth.
Velcro closures on clothing or sharp
objects may cause snagging or
scratches on the surface of the
seats. Make sure not to rub such
objects against the surface.
Cleaning the upholstery and inte-
rior 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.
Using anything but recommended
cleaners and procedures may affect
the fabric’s appearance and fire-
resistant properties.
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, cov-
ered with an oily, greasy or waxy
film), they should be cleaned with a
glass cleaner. Follow the directions
on the glass cleaner container.
CAUTION- Rear window
Do not scrape or scratch the
inside of the rear window. This
may result in damage of the rear
window defroster grid.

Maintenance
Window tinting precaution
Window tint(especially metallic film)
might cause communication disorder
or poor radio reception, and malfunc-
tion of the automatic lighting system
due to excessive change of illumina-
tion inside the vehicle. The solution
used might also flow into electric,
electronic devices causing disorder
and failure.

EMISSION CONTROL SYSTEM
The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty
information contained in the
Warranty & Consumer Information
manual 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 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
vehicle inspected and maintained by
an authorized Kia dealer in accor-
dance with the maintenance sched-
ule in this manual.Caution 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 (including ORVR:
Onboard Refueling Vapor
Recovery) system
The Evaporative Emission Control
System is designed to prevent fuel
vapors from escaping into the atmos-
phere.
(The ORVR system is designed to
allow the vapors from the fuel tank to
be loaded into a canister while refu-
eling at the gas station, preventing
the escape of fuel vapors into the
atmosphere.)
