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
vehicle is being driven in severe con-
ditions, more frequent oil and filter
changes are required.

Drive belts

Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil
saturation and replace if necessary.
Drive belts should be checked peri-
odically for proper tension and
adjusted as necessary.

Fuel filter (for gasoline)

This gasoline powered vehicle is
equipped with a lifetime fuel filter that
is integrated with the fuel tank.
Regular maintenance or replace-
ment is not needed but depends on
fuel quality. If there are any fuel relat-
ed problems like fuel flow restriction,
surging, loss of power, hard starting
problem etc, fuel filter inspection or
replacement may be needed.
The fuel filter be Inspected or
replaced by an authorized Kia deal-
er.

Maintenance

Vacuum crankcase ventilation
hoses (if equipped)

Inspect the surface of hoses for evi-
dence of heat and/or mechanical
damage. Hard and brittle rubber,
cracking, tears, cuts, abrasions, and
excessive swelling indicate deterio-
ration. Particular attention should be
pay particular attention to the hose
surfaces nearest to high heat
sources, such as the exhaust mani-
fold.
Inspect the hose routing to assure
that the hoses do not come in con-
tact with any heat source, sharp
edges or moving components which
might cause heat damage or
mechanical wear. Inspect all hose
connections, such as clamps and
couplings, to make sure they are
secure, and that no leaks are pres-
ent. Hoses should be replaced
immediately if there is any evidence
of deterioration or damage.

Air cleaner filter

A Genuine Kia air cleaner filter is
recommended when the filter is
replaced.

Spark plugs

Make sure to install new spark plugs
of the correct heat range.

Valve clearance (if equipped)

Inspect for excessive valve noise
and/or engine vibration and adjust if
necessary. An authorized Kia dealer
should perform this procedure.

Cooling system

Check the cooling system compo-
nents, such as the radiator, coolant
reservoir, hoses and connections for
leakage and damage. Replace any
damaged parts.

Coolant

The coolant should be changed at
the intervals specified in the mainte-
nance schedule.

Automatic transmission fluid

NOTICE

Automatic transmission fluid color
is usually red.
As the vehicle is driven, the auto-
matic transmission fluid will begin
to look darker.
This is normal, and you should not
judge the need to replace the fluid
based upon the changed color.

Brake hoses and lines

Visually check for proper installation,
chafing, cracks, deterioration and
any leakage. Replace any deteriorat-
ed or damaged parts immediately.

NOTICE

- NHTSA Safety

Corrosion Alert

NHTSA has warned all vehicle own-
ers of all brands that they must
maintain their vehicles in a manner
which will prevent brake hose and
brake line failures due to corrosion
when such vehicles are exposed to
winter road salt and related chemi-
cals. While serious corrosion condi-
tions typically only manifest them-
selves as safety issues after 7 years of
vehicle use, the corrosion process
starts immediately and thus under-
body cleaning maintenance must
commence from your vehicle's first
exposure to road salts and chemi-
cals. NHTSA urges vehicle owners to
take the following steps to prevent
corrosion:

(Continued)

(Continued)
1. Wash the undercarriage of your

vehicle regularly throughout the
winter and do a thorough washing
in the spring to remove road salt
and other de-icing chemicals.

2. Monitor the brake system for

signs of corrosion by having regu-
lar professional inspections and
watching for signs of problems,
including loss of brake fluid,
unusual leaks and soft or spongy
feel in the brake pedal.

3. Replace the entire brake pipe

assembly if you find severe corro-
sion that causes scaling or flaking
of brake components.

CAUTION

Use only specified automatic
transmission fluid. The use of a
non-specified fluid could result
in a transmission malfunction
and failure.

(Refer to

"Recommended lubricants and
capacities" in chapter 8.)

Maintenance

Brake fluid

Check the brake fluid level in the
brake fluid reservoir. The level should
be between “MIN” and “MAX” marks
on the side of the reservoir. Use only
hydraulic brake fluid conforming to
DOT 3 or DOT 4 specification.

Parking brake

Inspect the parking brake system
including the parking brake lever (or
pedal) and cables.

Brake discs, pads, calipers
and rotors

Check the pads for excessive wear,
discs for run out and wear, and
calipers for fluid leakage.

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 connections or
replace parts as necessary.

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 dam-
age. 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.

CHECKING FLUID LEVELS

When checking engine oil, engine
coolant, brake fluid, and washer fluid,
always be sure to clean the area
around any filler plug, drain plug, or
dipstick before checking or draining
any lubricant or fluid. This is espe-
cially important in dusty or sandy
areas and when the vehicle is used
on unpaved roads. Cleaning the plug
and dipstick areas will prevent dirt
and grit from entering the engine and
other mechanisms that could be
damaged.

ENGINE OIL

Checking the engine oil level

1. Be sure the vehicle is on level

ground.

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 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 com-
ponents.

Use only the specified engine oil.
(Refer to “Recommended lubricants
and capacities” in chapter 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.

Maintenance

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

• 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 while the
pressure is released from the cool-
ing system.
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 operating,

do not remove the radiator cap or
the drain plug while the engine and
radiator are hot. Hot coolant and
steam may still blow out under
pressure, causing serious injury.

WARNING

Removing radiator
cap

Never attempt to remove the
radiator cap while the engine is
operating or hot. Doing so
could result in serious personal
injury from escaping hot
coolant or steam.

CAUTION

-

Radiator cap

Never attempt to remove the
radiator cap while the engine is
operating or hot. Doing so
might lead to cooling system
and engine damage.

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 and L marks on the side
of the coolant reservoir when the
engine is cool.
If the coolant level is low, add enough
specified coolant to provide protec-
tion against freezing and corrosion.
Bring the level to F, but do not over-
fill. If frequent additions are required,
see an authorized Kia dealer for a
cooling system inspection.

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-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. This would
reduce the effectiveness of the
solution.

BRAKE FLUID

Checking the brake fluid level

Check the fluid level in the reservoir
periodically. The fluid level should be
between MAX (Maximum) and MIN
(Minimum) marks on the side of the
reservoir.
Before removing the reservoir cap
and adding brake fluid, clean the
area around the reservoir cap thor-
oughly to prevent brake fluid contam-
ination.

If the level is low, add fluid to the
MAX (Maximum) level. The level will
fall with accumulated mileage. This is
a normal condition associated with
the wear of 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
or capacities” in chapter 8.)

Never mix different types of fluid.

In the event the brake system
requires frequent additions of fluid,
the vehicle should be inspected by
an authorized Kia dealer.
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.

Brake 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

-

Proper fluid

Only use brake fluid in brake
system.

Small amounts of

improper fluids (such as engine
oil) can cause damage to the
brake system.

CAUTION

-

Brake fluid

Do not allow brake fluid to con-
tact the vehicle's body paint, as
paint damage will result.

WASHER FLUID

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 neces-
sary. 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.

WARNING

- Flammable

Fluid

Do not allow the washer fluid to
come in contact with open
flames or sparks.The windshield
washer fluid reservoir is flamma-
ble under certain circumstances.
This can result in a fire.

WARNING
