OWNER MAINTENANCE Owner maintenance schedule The following lists are vehicle checks and
inspections that should be performed by
the owner or an authorized Kia dealer at
the frequencies indicated to help ensure
safe, dependable operation of your vehi-
cle.
Any adverse conditions should be
brought to the attention of your dealer as
soon as possible.
These Owner Maintenance Checks are
generally not covered by warranties and
you may be charged for labor, parts and
lubricants used.When you stop for fuel: Check the engine oil level.
Check coolant level in coolant reser-
voir.
Check the windshield washer fluid
level.
Look for low or under-inflated tires.
While operating your vehicle: Note any changes in the sound of the
exhaust or any smell of exhaust fumes
in the vehicle.
Check for vibrations in the steering
wheel. Notice any increased steering
effort or looseness in the steering
wheel, or change in its straight-ahead
position.
Notice if your vehicle constantly turns
slightly or “pulls” to one side when trav-
eling on smooth, level road.
When stopping, listen and check for
strange sounds, pulling to one side,
increased brake pedal travel or “hard-
to-push” brake pedal.
If any slipping or changes in the oper-
ation of your transaxle occurs, check
the transaxle fluid level.
Check automatic transaxle P (Park)
function.
Check parking brake.
Check for fluid leaks under your vehicle
(water dripping from the air condition-
ing system during or after use is nor-
mal).
At least monthly: Check coolant level in the coolant
recovery reservoir.
Check the operation of all exterior
lights, including the stoplights, turn sig-
nals and hazard warning flashers.
Check the inflation pressures of all
tires including the spare.At least twice a year
(i.e., every Spring and Fall) : Check radiator, heater and air condi-
tioning hoses for leaks or damage.
Check windshield washer spray and
wiper operation. Clean wiper blades
with clean cloth dampened with wash-
er fluid.
Check headlight alignment.
Check muffler, exhaust pipes, shields
and clamps.
Check the lap/shoulder belts for wear
and function.
Check for worn tires and loose wheel
lug nuts.
WARNING
- Radiation
coolant
Be careful when checking your
engine coolant level when the
engine is hot. Scalding hot coolant
and steam may blow out under
pressure. This could cause burns or
other serious injury.

Maintenance
ENGINE OILChecking 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 only the specified engine oil. (Refer
to “Recommended Lubricants” later in this section.)
✽ ✽ NOTICEAlthough oil filters may have the same
external appearance, their internal
designs differ significantly. These filters
are not interchangeable. To avoid poten-
tial engine damage, use only the speci-
fied filter. Consult an authorized Kia
dealer.
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.
WARNING
Used engine oil may cause irritation
or cancer of the skin if left in con-
tact 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.

Maintenance14 7BRAKE FLUID Checking brake 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 fluid, clean the area around
the reservoir cap thoroughly to prevent
brake fluid contamination.
If your vehicle is equipped with a manual
transaxle, brake fluid is used as clutch
fluid.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.
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 Lubricants” later in
this section.)
Never mix different types of fluid.
✽ ✽
NOTICEDo not allow brake fluid to contact the
vehicle's body paint, as paint damage
will result. Brake 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 thrown
out. Don't put in the wrong kind of fluid.
A few drops of mineral-based oil, such
as engine oil, in your brake/clutch sys-
tem can damage brake/clutch system
parts.
WARNING -
Brake fluid
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.
WARNING -
Loss of brake
fluid
In the event the brake system
requires frequent additions of fluid,
the vehicle should be inspected by
an authorized Kia dealer.

Maintenance
New automatic transaxle fluid should
be red. The red dye is added so the
assembly plant can identify it as auto-
matic transaxle fluid and distinguish it
from engine oil or antifreeze. The red
dye, which is not an indicator of fluid
quality, is not permanent. As the vehi-
cle is driven, the automatic transaxle
fluid will begin to look darker. The
color may eventually appear light
brown.✽ ✽
NOTICEHave an Authorized Kia dealer inspect
or change the automatic transaxle fluid
according to the Scheduled
Maintenance at the beginning of this
section.Changing automatic transaxle
fluidHave automatic transaxle fluid changed
by an authorized Kia dealer according to
the Maintenance Schedule at the begin-
ning of this section.
Use only the specified automatic
transaxle fluid. (Refer to "Recommended
Lubricants" later in this section.)
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 necessary. 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.
Body lubrication All moving points of the body, such as
door hinges, hood hinges, and locks,
should be lubricated each time the
engine oil is changed. Use a non-freez-
ing lubricant on locks during cold weath-
er.
Make sure the engine hood secondary
latch keeps the hood from opening when
the primary latch is released.
LUBRICANTS AND FLUIDS
WARNING
- Coolant
Do not use radiator coolant or
antifreeze in the washer fluid
reservoir.
(Continued)
(Continued)
Radiator coolant can severely
obscure visibility when sprayed
on the windshield and may cause
loss of vehicle control or damage
to paint and body trim.
Windshield washer fluid agents
contain some amounts of alcohol
and can be flammable under cer-
tain circumstances. Do not allow
sparks or flame to contact the
washer fluid or the washer fluid
reservoir. Damage to the vehicle
or it's occupants could occur.
Windshield washer fluid is poi-
sonous to humans and animals.
Do not drink and avoid contacting
windshield washer fluid. Serious
injury or death could occur.
