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 concentration level at least
once a year, at the beginning of the
winter season, and before travelling
to a colder climate. Checking the coolant level
(Continued)
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 oper- ating, do not remove the radi-ator cap or the drain plugwhilst the engine and radiator
are hot. Hot coolant and
steam may still blow out
under pressure, causing seri-
ous injury.
WARNING
Removing radiatorcap
Never attempt to remove the radiator cap whilst the engine
is operating or hot. Doing somight lead to cooling system
and engine damage and could
result in serious personal
injury from escaping hotcoolant or steam.
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 whilst
the pressure is released fromthe cooling system.
(Continued)
CAUTION
When the engine overheatsfrom low engine coolant, sud-denly adding engine coolantmay cause cracks in theengine. To prevent damage, add engine coolant slowly insmall quantities.
Do not drive with no engine coolant. It may cause waterpump failure and engine seizure, etc.

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 (MAX) and L (MIN) marks
on the side of the coolant reservoirwhen the engine is cool.
If the coolant level is low, add enough
distilled (deionized) water. Bring the
level to F (MAX), but do not overfill. If
frequent additions are required, have
the system inspected by a professional
workshop. Kia recommends to visit an
authorised Kia dealer/service partner.
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-glycolwith 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, which would
reduce the effectiveness of thesolution.WARNING
The electric motor
(cooling fan) is con-
trolled by engine
coolant temperature,
refrigerant pressure
and vehicle speed. It may some-
times operate even when the
engine is not running. Use
extreme caution when working
near the blades of the cooling
fan so that you are not injured
by a rotating fan blades. As theengine coolant temperature
decreases, the electric motor
will automatically shut off. Thisis a normal condition.
If your vehicle is equipped with
GDI, the electric motor (cooling
fan) may operate until you dis-
connect the negative battery
cable.

BRAKE/CLUTCH FLUID (IF EQUIPPED)
Checking the brake/clutch
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/clutch fluid, clean
the area around the reservoir cap
thoroughly to prevent brake/clutchfluid contamination.
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 system checked by a pro-
fessional workshop. Kia recom-
mends to visit an authorised Kia
dealer/service partner.
Use only the specified brake fluid.
(Refer to “Recommended lubricantsand capacities” in chapter 9.)
Never mix different types of fluid.
ORP076084R
WARNING - Brake / clutch
fluid
When changing and adding
brake/clutch fluid, handle it
carefully. Do not let it come in
contact with your eyes. If
brake/clutch fluid should come
in contact with your eyes, imme-
diately flush them with a large
quantity of fresh tap water. Have
your eyes examined by a doctor
as soon as possible.
WARNING - Loss of
brake/clutch fluid
In the event the brake/clutch
system requires frequent addi-
tions of fluid, have the system
Inspected by a professional
workshop. Kia recommends tovisit an authorised Kia
dealer/service partner.
CAUTION
Do not allow brake/clutch fluid to contact the vehicle's bodypaint, as paint damage will result. Brake/clutch fluid, whichhas been exposed to open airfor an extended time should never be used as its quality can-not be guaranteed. It should beproperly disposed. Don't put in the wrong kind of fluid. A fewdrops of mineral-based oil, suchas engine oil, in your brake/ clutch system can damagebrake/clutch system parts.

FUEL FILTER (FOR DIESEL)
Draining water from fuel filter
The fuel filter for diesel engine plays
an important role of separating water
from fuel and accumulating the waterin its bottom.
If water accumulates in the fuel filter,
the warning light comes on when the
ignition switch is in the ON position. If this warning light illumi-
nates, take your car to a
professional workshop and
have drain the water and
check the system. Kia rec-
ommends to visit an authorised Kia
dealer/service partner. Filter replacement
It must be replaced when necessary,
and should not be washed.
You can clean the filter when inspect- ing the air cleaner element.
Clean the filter by using compressed
air.
1. Loosen the air cleaner cover
attaching clips and open the cover.
CAUTION
If the water accumulated in the
fuel filter is not drained at prop-er times, damages to the major parts such as the fuel systemcan be caused by water perme-ation in the fuel filter.

Maintenance
FUSESA vehicle’s electrical system is pro-
tected from electrical overload dam-
age by fuses.
This vehicle has 3 (or 4) fuse panels,
one located in the driver’s side panel
bolster, others in the engine com-
partment near the battery.
If any of your vehicle’s lights, acces-
sories, or controls do not work, check
the appropriate circuit fuse. If a fuse
has blown, the element inside thefuse will be melted.
If the electrical system does not
work, first check the driver’s sidefuse panel.
Always replace a blown fuse with
one of the same rating.
Before replacing a blown fuse, dis-
connect the negative battery cable.
If the replacement fuse blows, this
indicates an electrical problem. Avoid
using the system involved and imme-
diately consult a professional work-
shop. Kia recommends to consult an
authorised Kia dealer/service partner.
Three kinds of fuses are used: bladetype for lower amperage rating, car-tridge type, and multi fuse type for higher amperage ratings.
WARNING - Fuse
replacement
Never replace a fuse with any- thing but another fuse of the same rating.
A higher capacity fuse could cause damage and possibly a
fire.
Never install a wire or aluminum foil instead of the proper fuse -
even as a temporary repair. It
may cause extensive wiring
damage and a possible fire.
Do not arbitrarily modify or add-on electric wiring of the
vehicle.
