ENGINE OIL
Checking the engine oil level
1. Be sure the vehicle is on level ground.
2. Start the engine and allow it to reachnormal operating temperature.
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.
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 components.
Use only the specified engine oil. (Refer to “Recommended lubricants and capaci-ties” in section 8.)
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.
CAUTION - Replace engine oil
Do not overfill with engine oil.
Engine damage may result.

ENGINE COOLANT
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 section. The high-pressure cooling system has a
reservoir filled with year-round antifreeze
coolant. The reservoir is filled at the fac-
tory.
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 level
Check the condition and connections of
all cooling system hoses and heater
hoses. Replace any swollen or deterio-
rated hoses.
The coolant level should be filled
between F (MAX) and L (MIN) marks on
the side of the coolant reservoir when the
engine is cool.
WARNING - Cooling fan
Use caution when work-
ing near the blade of the
cooling fan. The electric
motor (cooling fan) is
controlled by engine
coolant temperature, refrigerant
pressure and vehicle speed. It may
sometimes operate even when the
engine is not running.
OAM072005
WARNING
Used engine oil may cause irrita-
tion or cancer of the skin if left in
contact with the skin for prolonged
periods of time. Used engine oil
contains chemicals that have
caused cancer in laboratory ani-
mals. Always protect your skin by
washing your hands thoroughly
with soap and warm water as soon
as possible after handling used oil.

727
Maintenance
If the coolant level is low, add enough
specified coolant to provide protection
against freezing and corrosion. Bring the
level to F (MAX), but do not overfill. If fre-
quent coolant addition is required, see an
authorized Kia dealer for a cooling sys-
tem inspection.
Recommended engine coolant
When adding coolant, use only deion-ized water or soft water for your vehicle
and never mix hard water in the
coolant filled at the factory. An improp-
er coolant mixture can result in serious
malfunction or engine damage.
The engine in your vehicle has alu- minum engine parts and must be pro-
tected by an ethylene-glycol-based
coolant to prevent corrosion and freez-
ing.
DO NOT USE alcohol or methanol coolant or mix them with the specified
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. For mixture percentage, refer to the fol-
lowing table.-15°C (5°F) 35

Turn the engine off and wait until it cools
down. Use care when removing the radi-
ator 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 continue turning counter-
clockwise to remove it.
Changing the coolant
Have the coolant changed by an author-
ized Kia dealer according to the
Maintenance Schedule at the beginning
of this section.
Put a thick cloth or fabric around the radi-
ator cap before refilling the coolant in
order to prevent the coolant from over-
flowing into engine parts such as the
alternator.CAUTION- Removing radi-
ator cap
Never attempt to remove
the radiator cap whilethe engine is operatingor hot. Doing so mightlead to cooling system and engine damage.

BRAKE/CLUTCH (IF EQUIPPED) FLUID
Checking the brake/clutch* fluid
level
Check the fluid level in the reservoir peri-
odically. 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/clutch* fluid contamina-
tion.
* if equippedIf the level is low, add fluid to the MAX
level. The level will fall with accumulated
mileage. This is a normal condition asso-
ciated with the wear of the brake linings
and/or clutch disc (if equipped). If the
fluid level is excessively low, have the
brake/clutch* system checked by an
authorized Kia dealer.
Use only the specified brake/clutch* fluid.
(Refer to “Recommended lubricants and capacities” in section 8.)
Never mix different types of fluid.
In the event the brake/clutch* system
requires frequent additions of fluid, the
vehicle should be inspected by an
authorized Kia dealer. 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, immediately flush them with a large
quantity of fresh tap water. Have your
eyes examined by a doctor as soon as
possible.
Brake/clutch* fluid, which has been
exposed to open air for an extended time
should never be used as its quality can-
not be guaranteed. It should be disposed
of properly.
CAUTION - Brake/clutch
fluid
Do not allow brake/clutch* fluid to
contact the vehicle's body paint, aspaint damage will result.
CAUTION - Proper fluid
Only use brake/clutch fluid in brake/clutch system. Smallamounts of improper fluids (suchas engine oil) can cause damage tothe brake/clutch system.

PARKING BRAKE
Checking the parking brake
Check the stroke of the parking brake by
counting the number of “clicks’’ heard
while fully applying it from the released
position. Also, the parking brake alone
should securely hold the vehicle on a fair-
ly steep grade. If the stroke is more or
less than specified, have the parking
brake adjusted by an authorized Kia
dealer.
Stroke : 6~8 “clicks’’ at a force of 20 kg (44 lbs, 196 N).
Filter replacement
It must be replaced when necessary, and
should not be washed.
You can clean the filter when inspecting
the air cleaner element.
Clean the filter by using compressed air. Replace the filter according to the
Maintenance Schedule.
If the vehicle is operated in extremely
dusty or sandy areas, replace the ele- ment more often than the usual recom-mended intervals. (Refer to“Maintenance under severe usage condi- tions” in this section.)

Battery recharging
Your vehicle has a maintenance-free,
calcium-based battery.
If the battery becomes discharged in a
short time (because, for example, the
headlights or interior lights were left on
while the vehicle was not in use),
recharge it by slow charging (trickle)
for 10 hours.
If the battery gradually discharges because of high electric load while the
vehicle is being used, recharge it at 20-
30A for two hours. When recharging the battery, observe
the following precautions:
The battery must be removed from the
vehicle and placed in an area with
good ventilation.
Watch the battery during charging, and stop or reduce the charging rate if the
battery cells begin gassing (boiling)
violently or if the temperature of the
electrolyte of any cell exceeds 49°C
(120°F).
Wear eye protection when checking the battery during charging.
Disconnect the battery charger in the following order.
1. Turn off the battery charger main switch.
2. Unhook the negative clamp from the negative battery terminal.
3. Unhook the positive clamp from the positive battery terminal.
Before performing maintenance or recharging the battery, turn off all
accessories and stop the engine.
The negative battery cable must be removed first and installed last when
the battery is disconnected.
