EXPLANATION OF SCHEDULED MAINTENANCE ITEMS
Engine oil and filter
The engine oil and filter should be
changed at the intervals specified in the
maintenance schedule. If the car is being
driven in severe conditions, more fre-
quent oil and filter changes are required.
Drive belts
Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil satu-
ration and replace if necessary. Drive
belts should be checked periodically for
proper tension and adjusted as neces-
sary.
Fuel filter
A clogged filter can limit the speed at
which the vehicle may be driven, damage
the emission system and cause multiple
issues such as hard starting. If an exces-
sive amount of foreign matter accumu-
lates in the fuel tank, the filter may
require replacement more frequently.
After installing a new filter, run the engine
for several minutes, and check for leaks
at the connections. Fuel filters should be
installed by an authorized KIA dealer.
Fuel lines, fuel hoses and con-
nections
Check the fuel lines, fuel hoses and con-
nections for leakage and damage. Have
an authorized KIA dealer replace any
damaged or leaking parts immediately.
Vapor hose and fuel filler cap
The vapor hose and fuel filler cap should
be inspected at those intervals specified
in the maintenance schedule. Make sure
that a new vapor hose or fuel filler cap is
correctly replaced.
Vacuum crankcase ventilation
hoses
Inspect the surface of hoses for evidence
of heat and/or mechanical damage. Hard
and brittle rubber, cracking, tears, cuts,
abrasions, and excessive swelling indi-
cate deterioration. Particular attention
should be paid to examine those hose
surfaces nearest to high heat sources,
such as the exhaust manifold.
Inspect the hose routing to assure that
the hoses do not come in contact with
any heat source, sharp edges or moving
component which might cause heat dam-
age or mechanical wear. Inspect all hose
connections, such as clamps and cou-
plings, to make sure they are secure, and
that no leaks are present. Hoses should
be replaced immediately if there is any
evidence of deterioration or damage.

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
re-insert 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.

tion or cancer of the skin if left in

periods of time. Used engine oil
contains chemicals that have
caused cancer in laboratory ani-
mals. Always protect your skin by

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 equipped If 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 andcapacities” in section 8.)
Never mix different types of fluid.
OTF070008
WARNING - Brake/clutch*
fluid
When changing and adding
brake/clutch* fluid, handle it care-
fully. 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.
WARNING - Loss of
brake/clutch* fluid
In the event the brake/clutch* sys-
tem requires frequent additions of
fluid, the vehicle should be inspect-
ed by an authorized KIA dealer.
CAUTION
Do not allow brake/clutch* fluid to
contact the vehicle's body paint, aspaint damage will result.
Brake/clutch* fluid, which has beenexposed to open air for an extendedtime should never be used as its quality cannot be guaranteed. Itshould be disposed of properly. Don't put in the wrong kind of fluid.A few drops of mineral-based oil, such as engine oil, in yourbrake/clutch* system can damagebrake/clutch* system parts.
