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)

Kia gasoline vehicle is equipped a
lifetime fuel filter that integrated with
the fuel tank. Regular maintenance
or replacement is not needed but
depends on fuel quality. If there are
some important safety matters like
fuel flow restriction, surging, loss of
power, hard starting problem etc, fuel
filter inspection or replace is needed.
The fuel filter be Inspected or
replaced by an authorized Kia dealer.

Fuel lines, fuel hoses and con-
nections

Check the fuel lines, fuel hoses and
connections for leakage and dam-
age. 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 inter-
vals specified in the maintenance
schedule. Make sure that a new
vapor hose or fuel filler cap is cor-
rectly replaced.

7 15

Maintenance

Vacuum crankcase ventilation
hoses

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
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 con-
tact with any heat source, sharp
edges or moving component 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 rec-
ommended when the filter is replaced.

Spark plugs

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

Valve clearance (if equipped)

Inspect excessive valve noise and/or
engine vibration and adjust if neces-
sary. An authorized Kia dealer
should perform the operation.

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 transaxle fluid

Automatic transaxle fluid should not
be checked under normal usage
conditions.
But in severe conditions, the fluid
should be changed at an authorized
Kia dealer in accordance to the
scheduled maintenance at the begin-
ning of this chapter.

✽

✽

NOTICE

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

NOTICE -

NHTSA Safety
Corrosion Alert

NHTSA has warned all vehicle own-
ers of all brands that they must main-
tain 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 chemicals. While seri-
ous corrosion conditions typically only
manifest themselves as safety issues
after 7 years of vehicle use, the corro-
sion process starts immediately and
thus underbody cleaning maintenance
must commence from your vehicle's
first exposure to road salts and chem-
icals. 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
transaxle fluid. The use of a non-
specified fluid could result in a
transaxle malfunction and fail-
ure. (Refer to "Recommended
lubricants and capacities" in
chapter 8.)

7 17

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 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 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

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.

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 reinsert it fully.

5. Pull the dipstick out again and

check the level. The level should
be between F and L.

CAUTION -

Replacing
engine oil

Do not overfill the engine oil. It
may damage the engine.

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.

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
might lead to cooling system
and engine damage and 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.

7 21

Maintenance

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
with phosphate 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
and 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.

OYG076015

CAUTION

- Brake fluid

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

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.

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

- Windshield

fluid

Do not drink the windshield
washer fluid. The windshield
washer fluid is poisonous to
humans and animals.

WARNING

- Coolant

• Do not use radiator coolant or

antifreeze in the washer fluid
reservoir.

• Radiator coolant can severely

obscure visibility when sprayed
on the windshield and may
cause loss of vehicle control.
