*1: If TOP TIER Detergent Gasoline is not available, one bottle of additive is recommended. Additives are available from your author-
ized Kia dealer along with information on how to use them. Do not mix other additives.
*2: As it is normal for engine oil to be consumed during driving, the engine oil level should be checked on regular basis. The engine
oil change interval for normal operating conditions is based on the use of the recommended engine specification. If the recom-
mended engine oil specification is not used, then replace the engine oil according to the maintenance schedule under severe
operating conditions.
*3: Inspect HSG belt for evidence of cuts, cracks, excessive wear or oil saturation and replace if necessary. If HSG belt noise
occurred, readjust HSG belt tension before replace.
*4: Fuel tank air filter are considered to be maintenance free but periodic inspection is recommended for this maintenance sched-
ule depends on fuel quality.

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 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.
Fuel tank and fuel cap
The fuel tank and fuel cap should be
inspected at those intervals specified
in the maintenance schedule. Make
sure that a new fuel tank or fuel cap
is correctly replaced.

Maintenance
16 7
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
recommended when the filter is
replaced.
Spark plugs
Make sure to install new spark plugs
of the correct heat range.
When assembling parts, be sure to
wipe the inside and outside of the
boot bottom of the ignition coil and
the insulator of the spark plug with a
soft cloth to prevent contamination of
the spark plug insulator.
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 (Engine / Inverter)
The coolant should be changed at
the intervals specified in the mainte-
nance schedule.

Maintenance
18 7
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
parts and, if necessary, repack the
grease.
Air conditioning refrigerant
Check the air conditioning lines and
connections for leakage and dam-
age.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.

Maintenance
ENGINE OIL
Checking the engine oil level
Engine oil is used for lubricating,
cooling, and operating various
hydraulic components in the engine.
Engine oil consumption while driving
is normal, and it is necessary to
check and refill the engine oil regu-
larly. Also, check and refill the oil
level within the recommended main-
tenance schedule to prevent deterio-
ration of oil performance.
Check the engine oil following the
below procedure.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, remove the oil
filler cap and pull the dipstick out.
Wait for 15 minutes for the oil to
return to the oil pan.
4. Wipe the dipstick clean and re-
insert it fully.
5. Pull the dipstick out again and
check the level. Check if the oil
level is between the F-L line, and if
it is below the L line, add enough
oil to bring the level to F line.
CAUTION
When you wipe the oil level
gauge, you should wipe it with a
clean cloth.
When mixed with debris, it can
cause engine damage.
WARNING- Radiator hose
Be very careful not to touch the
radiator hose when checking or
adding engine oil as it may be
hot enough to burn you.

Use a funnel to help prevent oil
from being spilled on engine com-
ponents.
Use only the specified engine oil.
(Refer to “Recommended lubricantsand capacities” in chapter 8.)
Do not spill engine oil when adding or changing engine oil. Wipe off
spilled oil immediately.
The engine oil consumption may increase while you break in a new
vehicle and it will be stabilized after
driving 4,000 miles (6,000 km).
The engine oil consumption can be affected by driving habits, climate
conditions, traffic conditions, oil
quality, etc. Therefore, it is recom-
mended that you inspect the
engine oil level regularly and refill it
if necessary.Changing the engine oil and
filter
If the maintenance schedule toreplace engine oil is exceeded, the
engine oil performance may deteri-
orate, and the engine condition
may be affected. Therefore,
replace the engine oil according to
the maintenance schedule.
To keep the engine in optimal con- dition, use the recommended
engine oil and filter. If the recom-
mended engine oil and filter are
not used replace it according to the
maintenance schedule under
severe usage conditions.
The purpose of the maintenance schedule for engine oil replace-
ment is to prevent oil deterioration
and it is irrelevant to oil consump-
tion. Check and refill engine oil reg-
ularly.
