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 transaxle occurs, check
the transaxle fluid level.
Check automatic transaxle 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).
At least monthly: Check coolant level in the coolant
recovery reservoir.
Check the operation of all exterior
lights, including the stoplights, turn sig-
nals and hazard warning flashers.
Check the inflation pressures of all
tires including the spare.At least twice a year
(i.e., every Spring and Fall) : Check radiator, heater and air condi-
tioning hoses for leaks or damage.
Check windshield washer spray and
wiper operation. Clean wiper blades
with clean cloth dampened with wash-
er fluid.
Check headlight alignment.
Check muffler, exhaust pipes, shields
and clamps.
Check the lap/shoulder belts for wear
and function.
Check for worn tires and loose wheel
lug nuts.
WARNING
- Radiation
coolant
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.

Maintenance
DRIVE BELTSDrive belts should be checked periodical-
ly for proper tension and replaced if nec-
essary. At the same time, belts should be
examined for cracks, wear, fraying or
other evidence of deterioration and
replaced if necessary.
Belt routing should also be checked to be
sure there is no interference between the
belts and other parts of the engine.
If the belt is too loose, have it replaced by
an authorized Kia dealer.Checking the compressor drive
beltHave the drive belts checked in accor-
dance with the maintenance schedule.
Checking the power steering fluid
level With the vehicle on level ground, check
the fluid level in the power steering reser-
voir periodically. The fluid should be
between MAX and MIN marks on the
side of the reservoir at the normal tem-
perature.
Before adding power steering fluid, thor-
oughly clean the area around the reser-
voir cap to prevent power steering fluid
contamination.
If the level is low, add fluid to the MAX
level.In the event the power steering system
requires frequent addition of fluid, the
vehicle should be inspected by an
authorized Kia dealer.
✽ ✽
NOTICE• To avoid damage to the power steer-
ing pump, do not operate the vehicle
for prolonged periods with a low
power steering fluid level.
• Never start the engine when the reser-
voir tank is empty.
• When adding fluid, be careful that
dirt does not get into the tank.
• Insufficient fluid can result in
increased steering effort; excessive
noise may also be present as the steer-
ing wheel is turned.
• The use of the non-specified fluid
could reduce the effectiveness of the
power steering wheel and cause dam-
age to it.Use only the specified power steering
fluid. (Refer to "Recommended
Lubricants" later in this section.)Power steering hoseCheck the hoses and hose connections
for leaks or damage before driving the
vehicle.

4. Tire ply composition and mate-
rialThe number of layers or plies of rub-
ber-coated fabric in the tire. Tire
manufacturers also must indicate the
materials in the tire, which include
steel, nylon, polyester, and others.
The letter "R" means radial ply con-
struction; the letter "D" means diago-
nal or bias ply construction; and the
letter "B" means belted-bias ply con-
struction.
5. Maximum permissible inflation
pressureThis number is the greatest amount
of air pressure that should be put in
the tire. Do not exceed the maximum
permissible inflation pressure. Refer
to the Tire and Loading Information
label for recommended inflation
pressure.6. Maximum load ratingThis number indicates the maximum
load in kilograms and pounds that
can be carried by the tire. When
replacing the tires on the vehicle,
always use a tire that has the same
load rating as the factory installed
tire.7. Uniform tire quality grading The following information relates to
the tire grading system developed by
the Canada Motor Vehicle Safety
Stardard (CMVSS) for grading tires
by tread wear, traction and tempera-
ture performance.Tread wear
The tread wear grade is a compara-
tive rating based on the wear rate of
the tire when tested under controlled
conditions on a specified govern-
ment test course. For example, a tire
graded 150 would wear one-and-a-
half times as well on the government
course as a tire graded 100.
The relative performance of tires
depends upon the actual conditions
of their use. However, performance
may differ from the norm because of
variations in driving habits, service
practices and differences in road
characteristics and climate.
These grades are molded on the
side-walls of passenger vehicle tires.
The tires available as standard or
optional equipment on Kia vehicles
may vary with respect to grade.
WARNING -
Tire age
Tires degrade over time, even
when they are not being used.
Regardless of the remaining
tread, it is recommended that
tires generally be replaced after
six (6) years of normal service.
Heat caused by hot climates or
frequent high loading conditions
can accelerate the aging
process. Failure to follow this
warning can result in sudden tire
failure, which could lead to a
loss of control and an accident
involving serious injury or death.

Maintenance32 7Traction - AA, A, B & C
The traction grades, from highest to
lowest, are AA, A, B and C. The
grades represent the tires ability to
stop on wet pavement as measured
under controlled conditions on spec-
ified government test surfaces of
asphalt and concrete. A tire marked
C may have poor traction perform-
ance.
Temperature -A, B & C
The temperature grades are A (the
highest), B and C. The grades repre-
sent the tire’s resistance to the gen-
eration of heat and its ability to dissi-
pate heat when tested under con-
trolled conditions on a specified
indoor laboratory test wheel.
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-
tionsAir 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.
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
tire failure. This can cause loss
of vehicle control and serious
injury or death.
