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.
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.

717
Maintenance
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 transmission fluid
Automatic transmission 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 transmission fluid color
is basically red.
As the vehicle is driven, the auto-
matic transmission 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.
Brake hoses and lines
Visually check for proper installation,
chafing, cracks, deterioration and
any leakage. Replace any deteriorat-
ed or damaged parts immediately.
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.)

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.
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.
