I : Inspect and if necessary, adjust, correct, clean or replace.
R : Replace or change.
*1: If TOP TIER Detergent Gasoline is not available, one bottle of additive is recommended. Additives are available from your autho r-
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 specifica\
tion. 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 noiseoccurred, 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.
❈ As it is normal for engine oil to be consumed during driving, the amount of engine oil should be checked regularly.
❈ The replacement cycle of engine oil is set by the period which the performance of our recommended engine oil is maintained.
Fuel filter (gasoline engine): The fuel filter is considered to be maintenance free but periodic inspection is recommended for this maintenance schedule depends on fuel quality.
- If there are some important safety matters like fuel flow restriction, surging, loss of power, hard starting problem etc., re place
the fuel filter immediately regardless of maintenance schedule and consu\
lt an authorized Kia dealer for details.

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 vapor hose and fuel filler cap
should be inspected at those inter-
vals specified in the maintenance
schedule. Make sure that a new fuel
tank and fuel cap is correctly
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.
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.
Dual clutch transmission Fluid
Inspect the dual clutch transmission
fluid according to the maintenance
schedule.
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 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 4 specification.
Parking brake
Inspect the parking brake system
including the parking brake pedal
and cables.
Brake discs, pads and calipers
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
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.
