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.

SEAT BELTS
Seat belt restraint system
Seat belts are designed to bear upon
the bony structure of the body, and
should be worn low across the front
of the pelvis, chest and shoulders, as
applicable; wearing the lap section of
the belt across the abdominal area
must be avoided.
Seat belts should be adjusted as
firmly as possible, consistent with
comfort, to provide the protection for
which they have been designed.
A slack belt will greatly reduce the
protection afforded to the wearer.
Care should be taken to avoid con-
tamination of the webbing with pol-
ishes, oils and chemicals, and partic-
ularly battery acid. Cleaning may
safely be carried out using mild soap
and water. The belt should be
replaced if webbing becomes frayed,
contaminated or damaged. For maximum restraint system pro-
tection, the seat belts must always
be used whenever the vehicle is
moving. A properly positioned
shoulder belt should be positioned
midway over your shoulder across
your collarbone.
Never allow children to ride in the front passenger seat. See child
restraint system section for further
discussion.
WARNING- Shoulder belt
Never wear the shoulder belt under your arm or behind
your back. An improperly
positioned shoulder belt can-
not protect the occupant in a
crash.
Always wear both the shoul- der portion and lap portion of
the lap/shoulder belt.
WARNING- Damagedseat belt
Replace the entire seat belt
assembly if any part of the web-
bing or hardware is damaged as
you can no longer be sure that a
damaged seat belt will provide
protection in a crash.

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.
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.
CAUTION- Proper Oil &
Refrigerant
It is important that the correcttype and amount of oil and refrig-erant is used, otherwise damageto the vehicle may occur. To pre-vent damage, the air conditioningsystem in your vehicle shouldonly be serviced by trained andcertified technicians.
