ENGINE OIL
Checking the engine oil level
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 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 reinsert it fully.5. Pull the dipstick out again and
check the level. The level should
be between F and L.
CAUTION - Replacing
engine oil
Do not overfill the engine oil. It
may damage the engine.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.

Maintenance
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 lubricants
and capacities” in chapter 8.)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.

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.

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.
CAUTION - 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.

723
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
coolant level gauge 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.
✽ ✽
NOTICE
Make sure the coolant cap is proper-
ly closed after refill of coolant.
Otherwise the engine could be over-
heated while driving.
1. Check if the radiator cap label is
on straight.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 can
operate even when the engine
is not running.

2. Make sure that the tiny protru-
sions inside the coolant cap are
securely interlocked.
Recommended engine coolant
When adding coolant, use only
deionized 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.For mixture percentage, refer to the
following table.

Maintenance
Changing the coolant
Have the coolant changed by an
authorized Kia dealer according to
the Maintenance Schedule at the
beginning of this chapter.
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 before
refilling the coolant in order to
prevent the coolant from over-
flowing into engine parts such
as the generator.

BRAKE FLUID
Checking the brake fluid level
Check the fluid level in the reservoir
periodically. The fluid level should be
between 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. Periodically check that the fluid level
in the brake fluid reservoir is
between MIN and MAX. The level will
fall with accumulated mileage. This is
a normal condition associated with
the wear of brake linings. If the fluid
level is excessively low, have the
brake system checked by an author-
ized 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.
CAUTION - 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
If washer fluid is insufficient, the
warning message will be popped up
on LCD display.
In this case, add washer fluid to the
reservoir tank.
Plain water may be used if washer
fluid is not available. However, use
washer solvent with antifreeze char-
acteristics in cold climates to prevent
freezing.
WARNING- Flammable
fluid
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.

Checking the parking brake
(if equipped)
Check whether the stroke is within
specification when the parking brake
pedal is depressed with 44 lbs, 196
N (20 kg) of force. Also, the parking
brake alone should securely hold the
vehicle on a fairly steep grade. If the
stroke is more or less than specified,
have the parking brake adjusted by
an authorized Kia dealer.

AIR CLEANER
Filter replacement
The air filter must be replaced when
necessary, and should not be
washed.
Have the air cleaner filter inspected or
replaced by an authorized Kia dealer.Replace the filter according to the
Maintenance Schedule.
If the vehicle is operated in extreme-
ly dusty or sandy areas, replace the
element more often than the usual
recommended intervals. (Refer to
“Maintenance under severe usage
conditions” in this chapter.)

CAUTION - Air filter
maintenance
Do not drive with the air clean-

excessive engine wear.
When removing the air cleaner
filter, be careful that dust or
dirt does not enter the air
intake, or damage may result.
Use a Kia genuine part. Use of
a non-genuine part could
damage the air flow sensor.
