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 car
is being driven in severe conditions,
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.
Fuel filter
A clogged filter can limit the speed at
which the vehicle may be driven,
damage the emission system and
cause multiple issues such as hard
starting. If an excessive amount of
foreign matter accumulates in the
fuel tank, the filter may require
replacement more frequently.
After installing a new filter, run the
engine for several minutes, and
check for leaks at the connections.
Fuel filters should be installed by an
authorized K900 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 K900 Kia
dealer replace any damaged or leak-
ing 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.
Air cleaner filter
A Genuine Kia air cleaner filter is
recommended when the filter is
replaced.
Spark plugs
Make sure to install new spark plugs
of the correct heat range.

Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and
any leakage. Replace any deteriorat-
ed or damaged parts immediately.
Brake fluid
Check brake fluid level in the brake
fluid reservoir. The level should be
between “MIN” and “MAX” marks on
the side of the reservoir. Use only
hydraulic brake fluid conforming to
DOT 3 or DOT 4 specification.
Brake discs, pads, calipers
and rotors
Check the pads for excessive wear,
discs for run out and wear, and
calipers for fluid leakage.
For more information on checking
the pads or lining wear limit, we rec-
ommend you to refer to the Kia web-
site.

)
Exhaust pipe and muffler
Visually inspect the exhaust pipes,
muffler and hangers for cracks, dete-
rioration, or damage. Start the
engine and listen carefully for any
exhaust gas leakage. Tighten con-
nections or replace parts as neces-
sary.
Suspension mounting bolts
Check the suspension connections
for looseness or damage. Retighten
to the specified torque.
Steering gear box, linkage &
boots/lower arm ball joint
With the vehicle stopped and engine
off, check for excessive free-play in
the steering wheel.
Check the linkage for bends or dam-
age. Check the dust boots and ball
joints for deterioration, cracks, or
damage. Replace any damaged
parts.
Drive shafts and boots
Check the drive shafts, boots and
clamps for cracks, deterioration, or
damage. Replace any damaged
parts and, if necessary, repack the
grease.
Air conditioning refrigerant
Check the air conditioning lines and
connections for leakage and dam-
age.

ENGINE OIL
Checking the engine oil level
1.Be sure the vehicle is on levelground.
2.Start the engine and allow it to reach normal operating tempera-
ture. 3.Turn the engine off and wait for a
few minutes (about 5 minutes) for
the oil to return to the oil pan.
4.Pull the dipstick out, wipe it clean, and re-insert it fully.
5.Pull the dipstick out again and check the level. The level should be
between F and L.
Do not spill engine oil, when adding or
changing engine oil. If you spill engine
oil in the engine room, wipe it off imme-
diately.
Replacement Engine Oil
Do not overfill with engine oil.
Engine damage may result.
CAUTION
Radiator hose
Be very careful not to touch the
radiator hose when checking or
adding the engine oil as it may
be hot enough to burn you.

If it is near or at L, add enough oil to
bring the level to F. Do not overfill.
Use a funnel to help prevent oil
from being spilled on engine com-
ponents.
Use only the specified engine oil.(Refer to “Recommended lubricantsand capacities” in section 8.)Changing the engine oil and
filter
Have engine oil and filter changed by
an authorized K900 Kia dealer
according to the Maintenance
Schedule at the beginning of this sec-
tion.
Engine oil contains chemicals
known to the State of California
to cause cancer, birth defects
and reproductive harm. Used
engine oil may cause irritation
or cancer of the skin if left in
contact with the skin for pro-
longed periods of time. Always
protect your skin by washing
your hands thoroughly with
soap and warm water as soon
as possible after handling used
oil.

ENGINE COOLANT
The high-pressure cooling system
has a reservoir filled with year-round
antifreeze coolant. The reservoir is
filled at the factory.
Check the antifreeze protection and
coolant level at least once a year, at
the beginning of the winter season,
and before traveling to a colder cli-
mate. Checking the coolant level Turn the engine off and wait until itcools down. Use extreme care
when removing the radiator cap.
Wrap a thick towel around it, and
turn it counterclockwise slowly to
the first stop. Step back while the
pressure is released from the cool-
ing system.
When you are sure all the pressure
has been released, press down on
the cap, using a thick towel, and
continue turning counterclockwise
to remove it.
Even if the engine is not operating, do not remove the radiator cap or
the drain plug while the engine and
radiator are hot. Hot coolant and
steam may still blow out under
pressure, causing serious injury.
Removing radia-
tor cap
Never attempt to remove the
radiator cap while the engine is
operating or hot. Doing so
might lead to cooling system
and engine damage and could
result in serious personal injury
from escaping hot coolant or
steam.

Check the condition and connections
of all cooling system hoses and
heater hoses. Replace any swollen
or deteriorated hoses.
The coolant level should be filled
between F and L marks on the side
of the coolant reservoir when the
engine is cool.If the coolant level is low, add enough
distilled (deionized) water. Bring the
level to F, but do not overfill. If fre-
quent additions are required, see an
authorized K900 Kia dealer for a
cooling system inspection.
Cooling fan
Use caution when
working near the
blade of the cooling
fan. The electric
motor (cooling fan) is
controlled by engine coolant
temperature, refrigerant pres-
sure and vehicle speed. it may
sometimes operate even when
the engine is not running. If
your vehicle is equipped with
GDI, the electric motor (cooling
fan) may operate until you dis-
connect the negative battery
cable.

Recommended engine coolant
When adding coolant, use onlydeionized water, distilled water or
soft water for your vehicle and
never mix hard water in the coolant
filled at the factory. An improper
coolant mixture can result in seri-
ous malfunction or engine dam-
age.
The engine in your vehicle has alu- minum engine parts and must be
protected by an ethylene-glycol-
based coolant to prevent corrosion
and freezing.
DO NOT USE alcohol or methanol coolant or mix them with the spec-
ified coolant.
Do not use a solution that contains more than 60% antifreeze or less
than 35% antifreeze, which would
reduce the effectiveness of the
solution.
50% water and 50% antifreeze mix is the easiest to mix together as it
will be same quantity of each and
can work reasonable for most situ-
ations. For mixture percentage, refer to the
following table.
✽
NOTICE
If in doubt about mix ratio 50%
water and 50% antifreeze mix is the
easiest to mix together as it will be
same quantity of each. It can work
reasonable for most temperature
range of -31°F and higher.
