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.
HSG (Hybrid starter & genera-
tor) belt
The HSG belt should be changed at
the intervals specified in the mainte-
nance schedule.
Fuel filter (for gasoline)
Kia gasoline vehicles are equipped a
lifetime fuel filter that is integrated
with the fuel tank. Regular mainte-
nance or replacement is generally
not needed but depends on fuel
quality. If there are some important
fuel related problems like fuel flow
restriction, surging, loss of power,
hard starting problem etc, fuel filter
inspection or replace is needed.
The fuel filter should 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.

Maintenance
Changing the engine oil and
filter
Have engine oil and filter changed by
an authorized Kia dealer according
to the Maintenance Schedule at the
beginning of this chapter.
WARNING- Used engine
oil
Used engine oil may cause irri-

left in contact with the skin for
prolonged periods of time.
Always protect your skin by
washing your hands thoroughly
with soap and warm water as
soon as possible after handling
used oil.

Cleaning the upholstery and inte-
rior trim
Vinyl
Remove dust and loose dirt from
vinyl with a whisk broom or vacuum
cleaner. Clean vinyl surfaces with a
vinyl cleaner.
Fabric
Remove dust and loose dirt from fab-
ric with a whisk broom or vacuum
cleaner. Clean with a mild soap solu-
tion recommended for upholstery or
carpets. Remove fresh spots imme-
diately with a fabric spot cleaner. If
fresh spots do not receive immediate
attention, the fabric can be stained
and its color can be affected. Also, its
fire-resistant properties can be
reduced if the material is not proper-
ly maintained.
Using anything but recommended
cleaners and procedures may affect
the fabric’s appearance and fire-
resistant properties.
Cleaning the lap/shoulder beltwebbing
Clean the belt webbing with any mild
soap solution recommended for
cleaning upholstery or carpet. Follow
the instructions provided with the
soap. Do not bleach or re-dye the
webbing because this may weaken it.
Cleaning the interior windowglass
If the interior glass surfaces of the
vehicle become fogged (that is, cov-
ered with an oily, greasy or waxy
film), they should be cleaned with a
glass cleaner. Follow the directions
on the glass cleaner container.
Window tinting precaution
Window tint(especially metallic film)
might cause communication disorder
or poor radio reception, and malfunc-
tion of the automatic lighting system
due to excessive change of illumina-
tion inside the vehicle. The solution
used might also flow into electric,
electronic devices causing disorder
and failure.
CAUTION- Rear window
Do not scrape or scratch theinside of the rear window. Thismay result in damage of the rearwindow defroster grid.

Specifications, Consumer information, Reporting safety defects
Recommended SAE viscosity
number
Engine oil viscosity (thickness) has an
effect on fuel economy and cold
weather operating (engine start and
engine oil flowability). Lower viscosity
engine oils can provide better fuel
economy and cold weather perform-
ance; however, higher viscosity
engine oils are required for satisfacto-
ry lubrication in hot weather. Using
oils of any viscosity other than those
recommended could result in engine
damage. When choosing an oil, con-
sider the range of temperature your
vehicle will be operated in before the
next oil change. Proceed to select the
recommended oil viscosity from the
chart.
