Fuel Additives
Kia recommends that you use good
quality gasolines treated with deter-
gent additives such as TOP TIER
Detergent Gasoline, which help pre-
vent deposit formation in the engine.
These gasolines will help the engine
run cleaner and enhance perform-
ance of the Emission Control System.
For more information on TOP TIER
Detergent Gasoline, please go to the
website (www.toptiergas.com)
For customers who do not use TOP
TIER Detergent Gasoline regularly,
and have problems starting or the
engine does not run smoothly, addi-
tives that can be purchased sepa-
rately may be added to the gasoline.
If TOP TIER Detergent Gasoline is
not available, one bottle of additive
should be added to the fuel tank at
every 7,500 miles (12,000 km) or
every engine oil change is recom-
mended. Additives are available from
your authorized Kia dealer along with
information on how to use them. Do
not mix other additives.
Operation in foreign countries
If you are going to drive your vehicle
in another country, be sure to:
Observe all regulations regarding
registration and insurance.
Determine that acceptable fuel is
available.

Be sure the exhaust system does
not leak.
The exhaust system should be
checked whenever the vehicle is
raised to change the oil or for any
other purpose. If you hear a change in
the sound of the exhaust or if you drive
over something that strikes the under-
neath side of the vehicle, have the
exhaust system checked as soon as
possible by an authorized Kia dealer.
WARNING- Engine
exhaust
Do not inhale exhaust fumes or
leave your engine running in a
enclosed area for a prolonged
time. Exhaust fumes contain
carbon monoxide, a colorless,
odorless gas that can cause
unconsciousness and death by
asphyxiation.WARNING- Open liftgate
Do not drive with the liftgate
open. Poisonous exhaust gases
can enter the passenger com-
partment. If you must drive with
the liftgate open proceed as fol-
lows:
1. Close all windows.
2. Open side vents.
3. Set the air intake control at
“Fresh”, the air flow control
at “Floor” or “Face” and the
fan at the highest speed.

DRIVER’S ATTENTION
The driver must be cautious in the
below situations as the function may
not work properly when recognition
of the lane marker is poor or limited
:

When lane and road condition is
poor
• It is difficult to distinguish the lane
marker from road when the lane
marker is covered with dust or
sand.
• It is difficult to distinguish the
color of the lane marker from
road.
• There is something looks like a
lane marker.
• The lane marker is indistinct or
damaged.
• The number of lanes increases/
decreases or the lane lines are
crossing (Driving through a toll
plaza/toll gate, merged/divided
lane).
• There are more than two lane
markers.
• The lane marker is very thick or
thin.
(Continued)(Continued)
• The lane marker is not visible due
to snow, rain, stain, a puddle or
other factors.
• A shadow is on the lane marker
because of a median strip,
guardrail, noise barriers and oth-
ers.
• When the lane markers are com-
plicated or a structure substitutes
for the lines such as a construc-
tion area.
• There are crosswalk signs or other
symbols on the road.
• The lane suddenly disappears
such as at the intersection.
• The lane marker in a tunnel is cov-
ered with dirt or oil and etc.
• The lane is very wide or narrow.

When external condition is inter-
vened
• The brightness of outside changes
suddenly when entering/existing a
tunnel or passing under a bridge.
• The headlamps are not on at night
or in a tunnel, or light level is low.
(Continued)(Continued)

Limitation of the function
If the driver turns on the turn signal
light or the emergency warning
light to change the lane
- Operate the turn signal light
switch before changing the lane
- If you change the lane without
operating the turn signal lights,
steering reaction force of the
wheel may occur.
Once LFA is turned on or the lane
is changed, the vehicle should be
in the center of the road to switch
to the steering assist mode. If the
driver keeps driving along the lane,
LFA will not assist the steering.
When the ESC or VSM is activat-
ed, the function does not assist
steering.
When driving on a curved road at a
high speed, steering assist mode
may not work.
When driving at a speed faster
than 110 mph (180 km/h), steering
assist mode may not work. When sudden steering is made,
the function could be temporarily
deactivated.
If you change the lane in a hurry,
the function does not assist the
steering.
If the vehicle suddenly stops, it
does not assist the steering.
If the lane is too narrow or too
wide, steering is not assisted.
If the function is not able to recog-
nize a vehicle in front and either of
the lanes is not recognized, the
steering is not assisted
If the radius is too small for the
curve
Cautions for the driver
If the lane recognition is difficult or
limited for LFA as shown below, the
driver may need to be careful
because it may not operate or may
cause unnecessary operation.
• Roads or lane markings in bad con-
dition
- When The lane is tainted or invisible
- When the driver cannot see the
lane due to rain, snow, dust,
sand, oil, puddles, etc
- When roads are set or the colors
of the lane and road are not dis-
tinctive
- If there is a sign other than the
lane near the lane or a mark sim-
ilar to the lane
- When the lane is not clear or
damaged
- If the road is covered in the shad-
ows of objects around the road,
such as medians, guard rails,
noise walls, and trees

Driving your vehicle
The use of chains may adversely
affect vehicle handling.
Do not exceed 20 mph (30 km/h)
or the chain manufacturer’s recom-
mended speed limit, whichever is
lower.
Drive carefully and avoid bumps,
holes, sharp turns, and other road
hazards, which may cause the
vehicle to bounce.
Avoid sharp turns or locked-wheel
braking.Use high quality ethylene gly-
col coolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type of
coolant that should be used because
it helps prevent corrosion in the cool-
ing system, lubricates the water
pump and prevents freezing. Be sure
to replace or replenish your coolant
in accordance with the maintenance
schedule in chapter 8. Before winter,
have your coolant tested to assure
that its freezing point is sufficient for
the temperatures anticipated during
the winter.
Check battery and cables
Winter puts additional burdens on
the battery system. Visually inspect
the battery and cables as described
in chapter 8. The level of charge in
your battery can be checked by an
authorized Kia dealer or a service
station.
Change to "winter weight" oil
if necessary
In some climates it is recommended
that a lower viscosity "winter weight"
oil be used during cold weather. See
chapter 9 for recommendations. If
you aren't sure what weight oil you
should use, consult an authorized
Kia dealer.
Check spark plugs and ignition
system
Inspect your spark plugs as
described in chapter 8 and replace
them if necessary. Also check all
ignition wiring and components to be
sure they are not cracked, worn or
damaged in any way.CAUTION- Snow chains
Chains that are the wrong size
or improperly installed can
damage your vehicle's brake
lines, suspension, body and
wheels.
Stop driving and retighten the
chains any time you hear them
hitting the vehicle.

OWNER MAINTENANCE
The following lists are vehicle checks
and inspections that should be per-
formed by the owner or an author-
ized Kia dealer at the frequencies
indicated to help ensure safe,
dependable operation of your vehi-
cle.
Any adverse conditions should be
brought to the attention of your deal-
er as soon as possible.
These Owner Maintenance Checks
are generally not covered by war-
ranties and you may be charged for
labor, parts and lubricants used.Owner maintenance schedule
When you stop for fuel:
Check the engine oil level.
Check the coolant level in coolant
reservoir.
Check the windshield washer fluid
level.
Look for low or under-inflated tires.
While operating your vehicle:
Note any changes in the sound of
the exhaust or any smell of
exhaust fumes in the vehicle.
Check for vibrations in the steering
wheel. Notice any increased steer-
ing effort or looseness in the steer-
ing wheel, or change in its straight-
ahead position.
Notice if your vehicle constantly
turns slightly or “pulls” to one side
when traveling on smooth, level
road.
When stopping, listen and check
for unusual sounds, pulling to one
side, increased brake pedal travel
or “hard-to-push” brake pedal.
If any slipping or changes in the
operation of your transmission
occurs, check the transmission
fluid level.
Check the dual clutch transmission
P (Park) function.
Check the parking brake.
Check for fluid leaks under your
vehicle (water dripping from the air
conditioning system during or after
use is normal).
WARNING- Hot coolant
Be careful when checking your
engine coolant level when the
engine is hot. Scalding hot
coolant and steam may blow
out under pressure.
WARNING
When you open the engine
hood, turn the Hybrid system
off. If not, it may result in death
or serious injury because of the
high voltage flow.

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 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.

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.
Dual clutch transmission Fluid
Inspect the dual clutch transmission
fluid according to the maintenance
schedule.

Check if the oil level is between the
F-L line and refill it if the oil level is
near the L line
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.)
The engine oil consumption may increase while you break in a new
vehicle and it will be stabilized after
driving 3,750 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.
The engine oil change interval is set for the purpose of preventing oil
deterioration, and is not related the
amount of oil consumption; so,
check and refill the amount of the
oil regularly.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.
If exceeding the maintenanceschedule for replacement of engine
oil, the engine oil performance may
deteriorate and the engine condition
may be affected. Therefore, the
replacement cycle should be
observed.
To keep the engine in optimal condi- tion, use recommended engine oil. If
not using the recommended oil,
replace it according to the severe
usage maintenance conditions.
WARNING - Used engine
oil
Used engine oil may cause irrita-
tion or cancer of the skin if left in
contact with the skin for pro-
longed periods of time. Always
