Introduction
Other fuels
Using fuels such as
- Silicone (Si) contained fuel,
- MMT (Manganese, Mn) containedfuel,
- Ferrocene (Fe) contained fuel, and
- Other metalic additives contained fuels,
may cause vehicle and engine dam-
age.
Also, the Malfunction Indicator Lamp
(MIL) may illuminate or cause plug-
ging, misfiring, poor acceleration,
engine stalling, catalyst melting,
abnormal corrosion, life cycle reduc-
tion, etc.
Gasoline containing MMT
Some gasoline contains harmful
manganese-based fuel additives
such as MMT (Methylcyclopentadi-
enyl Manganese Tricarbonyl).
Kia does not recommend the use of
gasoline containing MMT.
This type of fuel can reduce vehicle
performance and affect your emis-
sion control system.
The malfunction indicator lamp on
the cluster may come on.
Do not use methanol
Fuels containing methanol (wood alco-
hol) should not be used in your vehicle.
This type of fuel can reduce vehicle
performance and damage components
of the fuel system, engine control sys-
tem and emission control system.
✽ ✽

NOTICE
Your New Vehicle Limited
Warranty may not cover damage to
the fuel system and any perform-
ance problems that are caused by
the use of fuels containing methanol.
Fuel Additives
Kia recommends that you use good
quality gasolines treated with deter-
gent additives such as TOP TIER
Detergent Gasoline, which helps
prevent deposit formation in the
engine. These gasolines will help the
engine run cleaner and enhance per-
formance of the Emission Control
System. For more information on
TOP TIER Detergent Gasoline,
please go to the website (www
.top-
tiergas.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 you can buy separately
may be added to the gasoline. If TOP
TIER Detergent Gasoline is not avail-
able, one bottle of additive added to
the fuel tank at 7,500 miles or every
engine oil change is recommended.
Additives are available from your
authorized Kia dealer along with
information on how to use them. Do
not mix other additives.

NOTICE
• Replace the filter according to the
Maintenance Schedule.
If the vehicle is being driven in
severe conditions such as dusty,
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 con-
ditioning is reduced. Overfilling also
has a negative influence on the air
conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by
an authorized Kia dealer.
Air Conditioning refrigerant
label
❈ The actual Air Conditioning refrigerant
label in the vehicle may differ from the
illustration.
Each symbols and specification on
air conditioning refrigerant label
means as below ;
1. Classification of refrigerant
2. Amount of refrigerant
3. Classification of Compressor lubri- cant
Refer to chapter 8 for more detail loca-
tion of air conditioning refrigerant label.
WARNING
The air conditioning system for
the Hybrid vehicle should be
serviced by an authorized Kia
dealer. The Hybrid air condition-
ing system is connected to the
high voltage system and
requires special fluids, tools
and service procedures.
Improperly servicing the Hybrid
air conditioning system could
result in electrical shock, seri-
ous injury, or even death.
WARNING
Because the refriger-
ant is at very high
pressure, the air con-
ditioning system
should only be serv-
iced by trained and certified
technicians. It is important that
the correct type and amount of
oil and refrigerant is used, oth-
erwise damage to the vehicle
and personal injury may occur.

Driving your vehicle
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
underneath 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 an
enclosed area for a prolonged
time.
Exhaust fumes contain carbon
monoxide, a colorless, odorless
gas that can cause uncon-
sciousness 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.WARNING - California

Engine exhaust and a wide vari-
ety of automobile components
and parts, including compo-
nents found in the interior fur-
nishings in a vehicle, contain or
emit chemicals known to the
State of California to cause can-
cer and birth defects and repro-
ductive harm. In addition, cer-
tain fluids contained in vehicles
and certain products of compo-
nent wear contain or emit chem-
icals known to the State of
California to cause cancer and
birth defects or other reproduc-
tive harm.

Driving your vehicle
The use of chains may adverselyaffect 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 7. 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 section 7. Never attempt to check
the Hybrid High Voltage Battery. 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 8 for recommendations. If
you aren't sure what weight oil you
should use, consult an authorized
Kia dealer.
Check spark plugs and igni-
tion system
Inspect your spark plugs as
described in chapter 7 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
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 transaxle occurs,
check the transaxle fluid level.
Check the automatic transaxle 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.

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 car
is being driven in severe conditions,
more frequent oil and filter changes
are required.
Drive belts
Inspect all drive belts for evidence of
cuts, cracks, excessive wear or oil
saturation and replace if necessary.
Drive belts should be checked peri-
odically for proper tension and
adjusted as necessary.
Fuel filter
A clogged filter can limit the speed at
which the vehicle may be driven,
damage the emission system and
cause multiple issues such as hard
starting. If an excessive amount of
foreign matter accumulates in the
fuel tank, the filter may require
replacement more frequently.
After installing a new filter, run the
engine for several minutes, and
check for leaks at the connections.
Fuel filters should be installed 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.

Specifications, Consumer information, Reporting safety defects
Recommended SAE viscosity
numberEngine oil viscosity (thickness) has
an effect on fuel economy and cold
weather operating (engine start and
engine oil flowability). Lower viscosi-
ty engine oils can provide better fuel
economy and cold weather perform-
ance, however, higher viscosity
engine oils are required for satisfac-
tory lubrication in hot weather.Using oils of any viscosity other than
those recommended could result in
engine damage.
When choosing an oil, consider the
range of temperature your vehicle
will be operated in before the next oil
change. Proceed to select the rec-
ommended oil viscosity from the
chart.
CAUTION
Always be sure to clean the area
around any filler plug, drainplug, or dipstick before check-ing or draining any lubricant.This is especially important industy or sandy areas and whenthe vehicle is used on unpavedroads. Cleaning the plug anddipstick areas will prevent dirtand grit from entering theengine and other mechanismsthat could be damaged.
