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.

Safety features of your vehicle
SEAT BELTS
Seat belt restraint system
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. 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.
WARNING- Damaged
seat 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.WARNING- Twisted seat belt
Make sure your seat belt is not
twisted when worn. A twisted
seat belt may not properly pro-
tect you in an accident and
could even cut into your body.
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.

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.

Driving your vehicle
Driving in flooded areas
Avoid driving through flooded areas
unless you are sure the water is no
higher than the bottom of the wheel
hub. Drive through any water slowly.
Allow adequate stopping distance
because brake performance may be
affected.
After driving through water, dry the
brakes by gently applying them sev-
eral times while the vehicle is moving
slowly.
Highway driving
Tires
Adjust the tire inflation pressures to
specification. Low tire inflation pres-
sures will result in overheating and
possible failure of the tires.
Avoid using worn or damaged tires
which may result in reduced traction
or tire failure.
Never exceed the maximum tire
inflation pressure shown on the tires.
Fuel, engine coolant and engine oil
High speed travel consumes more
fuel than urban motoring. Do not for-
get to check both the engine coolant
and engine oil.
Drive belt
A loose or damaged drive belt may
result in overheating of the engine.
WARNING- Under/overinflated tires
Always check the tires for proper
inflation before driving.
Underinflated or overinflated
tires can cause poor handling,
loss of vehicle control, and sud-
den tire failure leading to acci-
dents, injuries, and even death.
For proper tire pressures, refer to
“Tires and wheels” in chapter 9.
WARNING- Tire tread
Always check the tire tread
before driving your vehicle.
Worn-out tires can result in loss
of vehicle control. Worn-out tires
should be replaced as soon as
possible. For further information
and tread limits, refer to "Tires
and wheels" in chapter 8.
