OWNER MAINTENANCE
Owner maintenance schedule
The following lists are vehicle checks and
inspections that should be performed by
the owner or an Authorized Kia Dealer at
the frequencies indicated to help ensure
safe, dependable operation of your vehi-
cle.
Any adverse conditions should be
brought to the attention of your dealer as
soon as possible.
These Owner Maintenance Checks are
generally not covered by warranties and
you may be charged for labor, parts and
lubricants used.
When you stop for fuel:
• Check the engine oil level.
• Check coolant level in coolant reser-
voir.
• Check the windshield washer fluid
level.
• Look for low or under-inflated tires.
While operating your vehicle:
• Note any changes in the sound of the
exhaust or any smell of exhaust fumes
in the vehicle.
• Check for vibrations in the steering
wheel. Notice any increased steering
effort or looseness in the steering
wheel, or change in its straight-ahead
position.
• Notice if your vehicle constantly turns
slightly or “pulls” to one side when trav-
eling on smooth, level road.
• When stopping, listen and check for
strange sounds, pulling to one side,
increased brake pedal travel or “hard-
to-push” brake pedal.
• If any slipping or changes in the oper-
ation of your transmission occurs,
check the transmission fluid level.
• Check automatic transmission P (Park)
function.
• Check parking brake.
• Check for fluid leaks under your vehicle
(water dripping from the air condition-
ing system during or after use is nor-
mal).
WARNING
Be careful when checking your
engine coolant level when the
engine is hot. Scalding hot coolant
and steam may blow out under
pressure. This could cause burns or
other serious injury.

TIRES AND WHEELS
Tires 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.
Inflation pressures
All tire pressures (including the
spare) should be checked every day
when the tires are cold. “Cold Tires”
means the vehicle has not been driv-
en for at least three hours or driven
less than 1.6 km (one mile).
Recommended pressures must be
maintained for the best ride, top vehi-
cle handling, and minimum tire wear.
(Refer to “Tires” in section 8,
Specifications.)All specifications (sizes and pres-
sures) can be found on a label
attached to the front driver’s door sill.
WARNING- Tire underin-
flation
Severe underinflation (70 kPa
(10 psi) or more) can lead to
severe heat build-up, causing
blowouts, tread separation and
other tire failures that can result
in the loss of vehicle control
leading to severe injury or
death. This risk is much higher
on hot days and when driving
for protracted periods at high
speeds.

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.
CAUTION - 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 1.6 km (one
mile) since startup.)
• Check the pressure of your
spare tire each time you check
the pressure of other tires.
• Never overload your vehicle.
Be careful not to overload a
vehicle luggage rack if your
vehicle is equipped with one.
• Worn, old tires can cause acci-
dents. If your tread is badly
worn, or if your tires have
been damaged, replace them.
CAUTION
• Underinflation also results in
excessive wear, poor handling
and reduced fuel economy.
Wheel deformation also is
possible. Keep your tire pres-
sures 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 possibility of dam-
age from road hazards.
CAUTION
• Warm tires normally exceed
recommended cold tire pres-
sures by 28 to 41 kPa (4 to 6
psi). Do not release air from
warm tires to adjust the pres-
sure or the tires will be under-
inflated.
• 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 the
cap have been lost, install new
one as soon as possible.

Sustained high temperature can
cause the material of the tires to
degenerate and reduce tires life, and
excessive temperature can lead to
sudden tires failure. Grades A and B
represent higher levels of perform-
ance on the laboratory test wheel
than the minimum required by the law.Tire terminology and defini-
tions
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.
WARNING- Tire
temperature
The temperature grade for this
tire is established for a tire that
is properly inflated and not
overloaded. Excessive speed,
underinflation, or excessive
loading, either separately or in
combination, can cause heat
build-up and possible sudden
tires failure. This can cause loss
of vehicle control and serious
injury or death.

LUBRICANT SPECIFICATIONS
Recommended lubricants
To help achieve proper engine and pow-
ertrain performance and durability, use
only lubricants of the proper quality. The
correct lubricants also help promote
engine efficiency that results in improved
fuel economy.
Engine oils labeled Energy Conserving
Oil are now available. Along with other
additional benefits, they contribute to fuel
economy by reducing the amount of fuel
necessary to overcome engine friction.
Often, these improvements are difficult to
measure in everyday driving, but in a
year’s time, they can offer significant cost
and energy savings.

Maintenance
Recommended SAE viscosity
number Engine oil viscosity (thickness) has an
effect on fuel economy and cold weather
operating (starting and oil flow). Lower
viscosity engine oils can provide better
fuel economy and cold weather perform-
ance, however, higher viscosity engine
oils are required for satisfactory lubrica-
tion in hot weather. Using oils of any vis-
cosity other than those recommended
could result in engine damage.When choosing an oil, consider the
range of temperature your vehicle will be
operated in before the next oil change.
Proceed to select the recommended oil
viscosity from the chart.

1. For better fuel economy, it is recommended to use the engine oil of a viscosity grade SAE 5W-
20,5W-30 (API SJ,SL / ILSAC GF-3). However, if the engine oil is not available in your coun-
try, select the proper engine oil using the engine oil viscosity chart.

CAUTION
Always be sure to clean the area
around any filler plug, drain plug, or
dipstick before checking or drain-
ing any lubricant. This is especially
important in dusty or sandy areas
and when the vehicle is used on
unpaved roads. Cleaning the plug
and dipstick areas will prevent dirt
and grit from entering the engine
and other mechanisms that could
be damaged.

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 preservative 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 preserva-
tive. 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 col-
lect on the underbody. If these materials
are not removed, accelerated 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 underbody
and wheel openings with lukewarm 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.
Aluminum wheel maintenance
The aluminum wheels are coated with a
clear protective finish.
• Do not use any abrasive cleaner, pol-
ishing compound, solvent, or wire
brushes on aluminum wheels. They
may scratch or damage the finish.
• Use only a mild soap or neutral deter-
gent, and rinse thoroughly with water.
Also, be sure to clean the wheels after
driving on salted roads. This helps pre-
vent corrosion.
• Avoid washing the wheels with high-
speed car wash brushes.
• Do not use any acid detergent. It may
damage and corrode the aluminum
wheels coated with a clear protective
finish.
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 for-
ward speed.
