CHECKING FLUID LEVELS
When checking engine oil, engine
coolant, brake fluid, and washer fluid,
always be sure to clean the area
around any filler plug, drain plug, or
dipstick before checking or draining
any lubricant or fluid. This is espe-
cially 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.

ENGINE OIL
Checking the engine oil level
Engine oil is used for lubricating,
cooling, and operating various
hydraulic components in the engine.
Engine oil consumption while driving
is normal, and it is necessary to
check and refill the engine oil regu-
larly. Also, check and refill the oil
level within the recommended main-
tenance schedule to prevent deterio-
ration of oil performance.
Check the engine oil following the
below procedure.1. Be sure the vehicle is on level
ground.
2. Start the engine and allow it to reach normal operating tempera-
ture.
3. Turn the engine off, remove the oil filler cap and pull the dipstick out.
Wait for 15 minutes for the oil to
return to the oil pan.
4. Wipe the dipstick clean and re- insert it fully. 5. Pull the dipstick out again and
check the level. Check if the oil
level is between the F-L line, and if
it is below the L line, add enough
oil to bring the level to F line.
CAUTION
When you wipe the oil levelgauge, you should wipe it with aclean cloth.
When mixed with debris, it cancause engine damage.
WARNING- 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.

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.

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.
