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 regardingregistration and insurance.
Determine that acceptable fuel is available.

NOTICE
• Replace the filter according to the
Maintenance Schedule.
If the vehicle is being driven in
severe conditions such as dusty or
rough roads, more frequent cli-
mate control air filter inspections
and changes are required.
• When the air flow rate suddenly decreases, the system should be
checked at an authorized Kia
dealer.
Checking the amount of air
conditioner refrigerant and
compressor lubricant
When the amount of refrigerant is
low, the performance of the air condi-
tioning is reduced. Overfilling also
has a negative impact on the air con-
ditioning system.
Therefore, if abnormal operation is
found, have the system inspected by
an authorized Kia dealer.
WARNING
The oil and refrigerant in your
vehicle's air conditioning sys-
tem is under very high pres-
sure. If proper service proce-
dures are not followed, an
explosion may result. To reduce
the risk of serious injury or
death, the air conditioning sys-
tem in your vehicle should only
be serviced by trained and cer-
tified technicians.
CAUTION
It is important that the correct
type and amount of oil andrefrigerant is used, otherwisedamage to the vehicle mayoccur. To prevent damage, theair conditioning system in yourvehicle should only be servicedby trained and certified techni-cians.

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- Engineexhaust
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 trunk
Do not drive with the trunk open.
Poisonous exhaust gases can
enter the passenger compart-
ment. If you must drive with the
trunk open proceed as follows:
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.

• There are more than two lane
markers.
• The lane marker is very thick or thin.
• 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 or other
objects.
• When the lane markers are com- plicated or a structure substitutes
for the lines such as a construction
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, etc. (Continued)(Continued)
  When external conditions inter-
vene
• The brightness outside changes suddenly when entering/exiting a
tunnel or passing under a bridge.
• The headlamps are not on at night or in a tunnel, or light level is low.
• There is a boundary structure in the roadway.
• The light reflects from the water on the road.
• When light shines brightly from behind the vehicle.
• The distance from the vehicle ahead is very short or the vehicle
ahead covers up the lane marker.
• You drive on a steep grade or a sharp curve.
• The vehicle vibrates heavily.
• The temperature near inside mir- ror is very high due to direct sun
light and etc. (Continued)(Continued)
  When front visibility is poor
• The lens or windshield is covered by foreign materials.
• The sensor cannot detect the lane because of fog, heavy rain or snow.
• The windshield is fogged by humid air in the vehicle.
• Putting something on the crash pad and etc.
WARNING
The Lane Keeping Assist sys-
tem is a system to help prevent
the driver from leaving the lane.
However, the driver should not
solely rely on the system but
always take the necessary
actions for safe driving prac-
tices.

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 candamage your vehicle's brakelines, suspension, body andwheels.
Stop driving and retighten the chains any time you hear themhitting 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 coolantreservoir.
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
roads.
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 automatic 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.
