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 chapter 8.)
 Do not spill engine oil when adding or changing engine oil. Wipe off
spilled oil immediately.
 The engine oil consumption may increase while you break in a new
vehicle and it will be stabilized after
driving 4,000 miles (6,000 km).
 The engine oil consumption can be affected by driving habits, climate
conditions, traffic conditions, oil
quality, etc. Therefore, it is recom-
mended that you inspect the
engine oil level regularly and refill it
if necessary.
 The engine oil change interval is set for the purpose of preventing oil
deterioration, and is not related to
the amount of oil consumption; so,
check and refill the amount of the
oil regularly.Changing the engine oil and
filter
Have engine oil and filter changed by
an authorized Kia dealer according
to the Maintenance Schedule at the
beginning of this chapter.
 If the maintenance schedule toreplace engine oil is exceeded, the
engine oil performance may deteri-
orate, and the engine condition
may be affected. Therefore,
replace the engine oil according to
the maintenance schedule.
 To keep the engine in optimal con- dition, use the recommended
engine oil and filter. If the recom-
mended engine oil and filter are
not used replace it according to the
maintenance schedule under
severe usage conditions.
 The purpose of the maintenance schedule for engine oil replace-
ment is to prevent oil deterioration
and it is irrelevant to oil consump-
tion. Check and refill engine oil reg-
ularly.

WARNING - Used engine
oil
Used engine oil may cause irrita-
tion 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.
Do not leave used engine oil
within the reach of children.
CAUTION
The engine oil is very hot imme- diately after the vehicle hasbeen driven and can causeburns during replacement.Replace the engine oil after theengine oil has cooled down.

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 it
cools 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.
WARNING
Removing radiator
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.

Maintenance
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
specified coolant to provide protec-
tion against freezing and corrosion.
Bring the level to F, but do not over-
fill. If frequent additions are required,
see an authorized Kia dealer for a
cooling system inspection.
Recommended engine coolant
 When adding coolant, use onlydeionized water or soft water for
your vehicle and never mix hard
water in the coolant filled at the fac-
tory. An improper coolant mixture
can result in serious malfunction or
engine damage.
 The engine in your vehicle has alu- minum engine parts and must be
protected by an ethylene-glycol
with phosphate 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. This would
reduce the effectiveness of the
solution.
✽ ✽
NOTICE
Make sure that the coolant cap is
properly closed after refilling the
coolant. Otherwise the engine could
overheat while driving.
OSC077016N
WARNING- 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.

WARNING
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 which may result in
serious injury.
CAUTION
Put a thick cloth or fabric around the radiator cap beforerefilling the coolant in order toprevent the coolant from over-flowing into engine parts suchas the alternator.

BRAKE FLUID (IF EQUIPPED)
Checking the brake fluid level
Check the fluid level in the reservoir
periodically. The fluid level should be
between the MAX (Maximum) and
MIN (Minimum) 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 until you
reach the MAX (Maximum) level. The
level will fall with accumulated
mileage. This is a normal condition
associated with the wear of brake lin-
ings. If the fluid level is excessively
low, have the brake system checked
by an authorized Kia dealer.
Use only the specified brake fluid.
(Refer to “Recommended lubricantsand capacities” in chapter 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 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.
Brake fluid which has been exposed
to open air for an extended time
should never be used as its quality
cannot be guaranteed. It should be
disposed of properly.
OYB076013CAUTION - brake fluid
Do not allow brake fluid to con-tact the vehicle's body paint, aspaint damage will result.
CAUTION - Proper fluid
Only use brake fluid in brakesystem. Small amounts ofimproper fluids (such as engineoil) can cause damage to thebrake system.

WASHER FLUID
Checking the washer fluid
level
The reservoir is translucent so that
you can check the level with a quick
visual inspection.
Check the fluid level in the washer
fluid reservoir and add fluid if neces-
sary. In warm climates, plain water
may be used if washer fluid is not
available. However, use washer sol-
vent with antifreeze characteristics in
cold climates to prevent freezing.
WARNING- Flammablefluid
Do not allow the washer fluid to
come in contact with open
flames or sparks. The windshield
washer fluid reservoir is flamma-
ble under certain circumstances.
This can result in a fire.WARNING- Windshield fluid
Do not drink the windshield
washer fluid. The windshield
washer fluid is poisonous to
humans and animals.
WARNING- Coolant
 Do not use radiator coolant or antifreeze in the washer fluid
reservoir.
 Radiator coolant can severely obscure visibility when sprayed
on the windshield and may
cause loss of vehicle control.
