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 climate.Checking the coolant levelTurn the vehicle 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 cooling system.
When you are sure all the pressure
has been released, press down on
the cap, using a thick towel, and con-
tinue turning counterclockwise to
remove it.
WARNING
Removing radiator
cap
Never attempt to remove the
radiator cap while the motor
compartment is operating or
hot. Doing so might lead to
cooling system damage and
could result in serious personal
injury from escaping hot
coolant or steam.
CAUTION - Radiator
/Inverter cap
Never attempt to remove theradiator or inverter cap whilethe motor is operating or hot.Doing so might lead to coolingsystem and motor damage.

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
motor room 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 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
damage.
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.
The cooling circuit of a vehicle equipped with a heat pump system
may freeze in extremely low tem-
perature when the concentration of
the antifreezing liquid is below
45%.
OPSE074002
WARNING- Cooling fan
Use caution when
working near the
blade of the cooling
fan. The electric
motor (cooling fan) is
controlled by coolant tempera-
ture, refrigerant pressure and
vehicle speed. it may some-
times operate even when the
vehicle is not running.

723
Maintenance
For mixture percentage, refer to the
following table.Changing the coolant
Have the coolant changed by an
authorized Kia dealer according to
the Maintenance Schedule at the
beginning of this chapter.
Put a thick cloth around the radiator
cap before refilling the coolant in
order to prevent the coolant from
overflowing into motor compartment.

WARNING
Radiator cap
Do not remove the radiator cap
when the motor compartment
and radiator are hot. Scalding
hot coolant and steam may
blow out under pressure which
may result in 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 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.
OPSE074003
CAUTION - Proper fluid
Only use brake fluid in brake
system. Small amounts ofimproper fluids can cause dam-age to the brake system.

725
Maintenance
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.

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. Plain water may be used if
washer fluid is not available.
However, use washer solvent with
antifreeze characteristics in cold cli-
mates to prevent freezing.
OPSE074004
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- 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.
WARNING- Windshield
fluid
Do not drink the windshield
washer fluid. The windshield
washer fluid is poisonous to
humans and animals.

CLIMATE CONTROL AIR FILTER
Filter inspection & replacement
The climate control air filter should
be replaced according to the mainte-
nance schedule. If the vehicle is
operated in severely air-polluted
cities or on dusty rough roads for a
long period, it should be inspected
more frequently and replaced earlier.
When you replace the climate control
air filter, replace it performing the fol-
lowing procedure, and be careful to
avoid damaging other components.1. Open the glove box. 2. With the glove box open, remove the Air filter cover.

3. Remove the climate control air fil-
ter case by pulling out both sides
of the cover. 4. Replace the climate control air filter.
5. Reassemble in the reverse order
of disassembly.
When replacing the climate control
air filter install it properly. Otherwise,
the system may produce noise and
the effectiveness of the filter may be
reduced.

WIPER BLADES
Blade inspection
Commercial hot waxes applied by
automatic vehicle washes have been
known to make the windshield diffi-
cult to clean.Contamination of either the wind-
shield or the wiper blades with for-
eign matter can reduce the effective-
ness of the windshield wipers.
Common sources of contamination
are insects, tree sap, and hot wax
treatments used by some commer-
cial vehicle washes. If the blades are
not wiping properly, clean both the
window and the blades with a good
cleaner or mild detergent, and rinse
thoroughly with clean water.
Blade replacement
When the wipers no longer clean
adequately, the blades may be worn
or cracked, and require replacement.
To prevent damage to the wiper arms
or other components, do not attempt
to move the wipers manually.
The use of a non-specified wiper
blade could result in wiper malfunc-
tion and failure.
1JBA5122CAUTION- Wiper blades
To prevent damage to the wiper
blades, do not use gasoline,kerosene, paint thinner, or othersolvents on or near them.
