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.

Changing the coolant
Have coolant changed by an author-
ized K900 Kia dealer according to
the Maintenance Schedule at the
beginning of this section.
Put a thick cloth around the radiator
cap before refilling the coolant in
order to prevent the coolant from
overflowing into engine parts such as
the generator.
Radiator cap
Do not remove the radiator cap
when the engine and radiator
are hot. Scalding hot coolant
and steam may blow out under
pressure causing serious injury.

BRAKE FLUID
Checking the brake fluid level
Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX and MIN marks on the
side of the reservoir.
Before removing the reservoir cap
and adding brake fluid, clean the
area around the reservoir cap thor-oughly to prevent brake fluid contam-
ination.
If the level is low, add fluid to the
MAX level. The level will fall with
accumulated mileage. This is a nor-
mal condition associated with the
wear of the brake linings. If the fluid
level is excessively low, have the
brake system checked by an author-
ized K900 Kia dealer.
Use only the specified brake fluid.
(Refer to “Recommended lubricantsor capacities” in section 8.)
Never mix different types of fluid.
In the event the brake system
requires frequent additions of fluid,
the vehicle should be inspected by
an authorized K900 Kia dealer. When changing and adding brake
fluid, handle it carefully. Do not let it
come in contact with your eyes. If
brake fluid should come in contact
with your eyes, immediately flush
them with a large quantity of fresh
tap water. Have your eyes examined
by a doctor as soon as possible.
Proper fluid
Only use brake fluid in brake
system. Small amounts of
improper fluids (such as engine
oil) can cause damage to the
brake system.
CAUTION
Brake fluid
Do not allow brake fluid to con-
tact the vehicle's body paint, as
paint damage will result.

POWER STEERING FLUID
Checking the power steering
fluid level
With the vehicle on level ground,
check the fluid level in the power
steering reservoir periodically. The
fluid should be between MAX and
MIN marks on the side of the gauge
at the normal temperature.
Before adding power steering fluid,
thoroughly clean the area around the
reservoir cap to prevent power steer-
ing fluid contamination.
If the level is low, add fluid to the
MAX level.In the event the power steering sys-
tem requires frequent addition of
fluid, the vehicle should be inspected
by an authorized K900 Kia dealer.
Too little fluid can result in increased
steering effort and/or noise from the
power steering system.
✽
NOTICE
Check that the fluid level is in the
"HOT" range on the gauge. If the
fluid is cold, check that it is in the
"COLD" range.
Use only the specified power steer-
ing fluid. (Refer to "Recommendedlubricants or capacities" in section8.)
Checking the power steering
hose
Check the connections for oil leaks,
damage and twists in the power
steering hose before driving.
Low power steering fluid
To avoid damage to the power steering pump, do not operate
the vehicle for prolonged peri-
ods with a low power steering
fluid level.
Never start the engine when the reservoir tank is empty.
When adding fluid, be careful that dirt does not get into the
tank.
The use of the non-specified fluid could reduce the effective-
ness of the power steering sys-
tem and cause damage to it.

2.Replace the air cleaner filter afterpulling up the locking tab (1).
3.Lock the cover with the cover attaching clips. Replace the filter according to the
Maintenance Schedule.
If the vehicle is operated in extreme-
ly dusty or sandy areas, replace theelement more often than the usualrecommended intervals. (Refer to“Maintenance under severe usageconditions” in this section.)
OKH073013NAir Filter Maintenance
Do not drive with the air clean- er removed; this will result in
excessive engine wear.
When removing the air clean- er filter, be careful that dust or
dirt does not enter the air
intake, or damage may result.
Use a Kia genuine part. Use of non-genuine parts could dam-
age the air flow sensor.
