Exhaust pipe and muffler
Visually inspect the exhaust pipes,
muffler and hangers for cracks, dete-
rioration, or damage. Start the
engine and listen carefully for any
exhaust gas leakage. Tighten con-
nections or replace parts as neces-
sary.
Suspension mounting bolts
Check the suspension connections
for looseness or damage. Retighten
to the specified torque.
Steering gear box, linkage &
boots/lower arm ball joint
With the vehicle stopped and engine
off, check for excessive free-play in
the steering wheel.
Check the linkage for bends or dam-
age. Check the dust boots and ball
joints for deterioration, cracks, or
damage. Replace any damaged
parts.
Drive shafts and boots
Check the drive shafts, boots and
clamps for cracks, deterioration, or
damage. Replace any damaged
parts and, if necessary, repack the
grease.
Air conditioning refrigerant
Check the air conditioning lines and
connections for leakage and dam-
age.

ENGINE OIL
Checking the engine oil level
1. Be sure the vehicle is on levelground.
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.
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 lubricantsand capacities” 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.

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 may cause irri-
tation or cancer of the skin if
left in contact with the skin for
prolonged 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
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 reservoir
when the engine is cool.
If the coolant level is low, add enough
specified coolant or distilled (deion-
ized) water to provide protection
against freezing and corrosion. Bring
the level to F (MAX), but do not over-
fill. If frequent coolant addition is
required, see an authorized Kia deal-
er 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-
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 the
solution.
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.

CAUTION- Removing
radiator cap
Never attempt toremove the radiator cap while the engineis operating or hot.Doing so might lead to cooling system andengine damage.
For mixture percentage, refer to the
following table.
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.

Maintenance
Turn the engine off and wait until it
cools down. Use care when remov-
ing the radiator cap. Wrap a thick
towel around it, and turn it counter-
clockwise 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.Changing the coolant
Have the coolant changed by an
authorized Kia dealer according to
the Maintenance Schedule at the
beginning of this section.

BRAKE/CLUTCH (IF EQUIPPED) FLUID
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/clutch*
fluid contamination.
* if equipped 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 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 lubri-cants and capacities” in chapter 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 doc-
tor 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 cannot be guaranteed. It
should be disposed of properly.
CAUTION - Brake/clutch fluid
Do not allow brake/clutch* fluidto contact the vehicle's bodypaint, as paint damage willresult.
CAUTION - Proper fluid
Only use brake/clutch fluid inbrake/clutch system. Smallamounts of improper fluids(such as engine oil) can causedamage to the brake/clutch sys-tem.

AIR CLEANER
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. Replace the filter according to the
Maintenance Schedule.
If the vehicle is operated in extreme-
ly dusty or sandy areas, replace theelement more often than the usualrecommended intervals. (Refer to“Maintenance under severe usageconditions” in this chapter.)

CAUTION - Air filter
maintenance
Do not drive with the air clean- er removed; this will result inexcessive engine wear.
When removing the air cleaner filter, be careful that dust ordirt does not enter the airintake, or damage may result.
Use a Kia genuine part. Use of nongenuine part could dam-age the air flow sensor.
