EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
Engine oil and filter
The engine oil and filter should be
changed at the intervals specified in
the maintenance schedule. If the
vehicle is being driven in severe con-
ditions, more frequent oil and filter
changes are required.
Drive belts
Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil
saturation and replace if necessary.
Drive belts should be checked peri-
odically for proper tension and
adjusted as necessary.
Fuel filter (for gasoline)
Kia gasoline vehicle is equipped a
lifetime fuel filter that integrated with
the fuel tank. Regular maintenance
or replacement is not needed but
depends on fuel quality. If there are
some important safety matters like
fuel flow restriction, surging, loss of
power, hard starting problem etc, fuel
filter inspection or replace is needed.
The fuel filter be Inspected or
replaced by an authorized Kia dealer.
Fuel lines, fuel hoses and con-
nections
Check the fuel lines, fuel hoses and
connections for leakage and dam-
age. Have an authorized Kia dealer
replace any damaged or leaking
parts immediately.
Vapor hose and fuel filler cap
The vapor hose and fuel filler cap
should be inspected at those inter-
vals specified in the maintenance
schedule. Make sure that a new
vapor hose or fuel filler cap is cor-
rectly replaced.

TIRES AND WHEELS
Tire care
For proper maintenance, safety, and
maximum fuel economy, you must
always maintain recommended tire
inflation pressures and stay within
the load limits and weight distribution
recommended for your vehicle.
Recommended cold tire infla-
tion pressures
All tire pressures (including the
spare) should be checked when the
tires are cold. “Cold Tires” means the
vehicle has not been driven for at
least three hours or driven less than
1 mile (1.6 km).
Recommended pressures must be
maintained for the best ride, top vehi-
cle handling, and minimum tire wear.
For recommended inflation pressure
refer to “Tire and wheels” in chapter
8.All specifications (sizes and pres-
sures) can be found on a label
attached to the driver’s side center
pillar.
WARNING - Tire underin-
flation
Inflate your tires consistent with
the instructions provided in this
manual. Severe underinflation
(10 psi (70 kPa) or more) can
lead to severe heat build-up,
causing blowouts, tread separa-
tion and other tire failures that
can result in the loss of vehicle
control. This risk is much higher
on hot days and when driving
for long periods at high speeds.

Underinflation also results in
excessive wear, poor handling and
reduced fuel economy. Wheel
deformation also is possible. Keep
your tire pressures at the proper
levels. If a tire frequently needs
refilling, have it checked by an
authorized Kia dealer.
Overinflation produces a harsh
ride, excessive wear at the center
of the tire tread, and a greater pos-
sibility of damage from road haz-
ards.
Warm tires normally exceed rec-
ommended cold tire pressures by 4
to 6 psi (28 to 41 kPa). Do not
release air from warm tires to
adjust the pressure or the tires will
be underinflated.
Be sure to reinstall the tire inflation
valve caps. Without the valve cap,
dirt or moisture could get into the
valve core and cause air leakage. If
a valve cap is missing, install a
new one as soon as possible.Tire pressure
Always observe the following:
Check tire pressure when the tires
are cold. (After vehicle has been
parked for at least three hours or
hasn't been driven more than 1
mile (1.6 km) since startup.)
Check the pressure of your spare
tire each time you check the pres-
sure of other tires.
Never overload your vehicle. Be
careful not to overload a vehicle
luggage rack if your vehicle is
equipped with one.
Checking tire inflation pres-
sure
Check your tires once a month or
more.
Also, check the tire pressure of the
spare tire.
How to check
Use a good quality gauge to check
tire pressure. You can not tell if your
tires are properly inflated simply by
looking at them. Radial tires may
look properly inflated even when
they're underinflated.
Check the tire's inflation pressure
when the tires are cold. - "Cold"
means your vehicle has been sitting
for at least three hours or driven no
more than 1 mile (1.6 km).
WARNING - Tire Inflation
Overinflation or underinflation
can reduce tire life, adversely
affect vehicle handling, and
lead to sudden tire failure. This
could result in loss of vehicle
control and potential injury.

Temperature -A, B & C
The temperature grades are A (the
highest), B and C representing the
tire’s resistance to the generation of
heat and its ability to dissipate heat
when tested under controlled condi-
tions on a specified indoor laboratory
test wheel.
Sustained high temperature can
cause the material of the tire to
degenerate and reduce tire life, and
excessive temperature can lead to
sudden tire failure. The grade C cor-
responds to a level of performance
which all passenger car tires must
meet under the Federal Motor
Vehicle Safety Standard No. 109.
Grades B and A represent higher
levels of performance on the labora-
tory test wheel than the minimum
required by law.Tire terminology and definitions
Air Pressure:The amount of air
inside the tire pressing outward on
the tire. Air pressure is expressed in
kilopascal (kPa) or pounds per
square inch (psi).
Accessory Weight:This means the
combined weight of optional acces-
sories. Some examples of optional
accessories are, automatic transmis-
sion, power seats, and air condition-
ing.
Aspect Ratio:The relationship of a
tire's height to its width.
Belt:A rubber coated layer of cords
that is located between the plies and
the tread. Cords may be made from
steel or other reinforcing materials.
Bead:The tire bead contains steel
wires wrapped by steel cords that
hold the tire onto the rim.
Bias Ply Tire:A pneumatic tire in
which the plies are laid at alternate
angles less than 90 degrees to the
centerline of the tread.Cold Tire Pressure:The amount of
air pressure in a tire, measured in
kilopascals (kPa) or pounds per
square inch (psi) before a tire has
built up heat from driving.
Curb Weight:This means the weight
of a motor vehicle with standard and
optional equipment including the
maximum capacity of fuel, oil and
coolant, but without passengers and
cargo.
DOT Markings:A code molded into
the sidewall of a tire signifying that
the tire is in compliance with the U.S.
Department of Transportation motor
vehicle safety standards. The DOT
code includes the Tire Identification
Number (TIN), an alphanumeric des-
ignator which can also identify the
tire manufacturer, production plant,
brand and date of production.

Maintenance
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 replace-
ment, be sure the body shop applies
anti-corrosion materials to the parts
repaired or replaced.
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. The National Highway Traffic
Safety Administration has warned all
vehicle owners of all brands of the
need to take the following steps:
Wash the undercarriage of your
vehicle regularly during the winter
and whenever your vehicle has
been exposed to such salts or
chemicals.CAUTION - Drying vehicle
Wiping dust or dirt off the
body with a dry cloth will
scratch the finish.
Do not use steel wool, abra-
sive cleaners, acid detergents
or strong detergents contain-
ing high alkaline or caustic
agents on chrome-plated or
anodized aluminum parts.
This may result in damage to
the protective coating and
cause discoloration or paint
deterioration.
