Air conditioning system opera-
tion tips
• If the vehicle has been parked in directsunlight during hot weather, open the
windows for a short time to let the hot
air inside the vehicle escape.
• To help reduce moisture inside of the windows on rainy humid days,
decrease the humidity inside the vehi-
cle by operating the air conditioning
system.
• During air conditioning system opera- tion, you may occasionally notice a
slight change in the engine speed as
the air conditioning compressor cycles
on. This is a normal system operation
characteristics.
• Use the air conditioning system every month only for a few minutes to ensure
maximum system performance.
• When using the air conditioning sys- tem, you may notice clear water drip-
ping (or even pudding) on the ground
under the passenger side of the vehi-
cle. This is a normal system operation
characteristics. • Operating the air conditioning system
in the recirculated air position does
provide maximum cooling, however,
continual operation in this mode may
cause the air inside the vehicle to
become stale.
Checking the amount of air con-
ditioner refrigerant and compres-
sor lubricant
When the amount of refrigerant is low,
the performance of the air conditioning is
reduced. Overfilling also has a bad influ-
ence on the air conditioning system.
Therefore, if abnormal operation is
found, have the system inspected by an
authorized Kia dealer.
CAUTION
When the performance of the air
conditioning system is reduced it is
important that the correct type and amount of oil and refrigerant isu sed. Otherwis e, damage to the
compressor and abnormal system operation may occur.
CAUTION
When us ing the air conditioning
s ystem, monitor the temperature
gauge closely while driving up hill s
or in heavy traffic when out side
temperatures are high. Air condi- tioning system operation may
caus e engine overheating.
Continue to use the blower fan but turn the air conditioning system off
if the temperature gauge indicate s
engine overheating.
WARNING
The air conditioning system should
be serviced by an authorized Kia
dealer. Improper service may cause
serious injury to the per son per-
forming the service.

FUEL REQUIREMENTS
Gasoline engine (unleaded)
Your new Kia vehicle is designed to use
only unleaded fuel with a minimum
Octane Rating of 87 Anti-Knock Index
(AKI).
Gasoline containing alcohol and
methanol
Gasohol, a mixture of gasoline and
ethanol (also known as grain alcohol),
and gasoline or gasohol containing
methanol (also known as wood alcohol)
are being marketed along with or instead
of leaded or unleaded gasoline.
Do not use gasohol containing more than
10% ethanol, and do not use gasoline or
gasohol containing any methanol. Either
of these fuels may cause drivability prob-
lems and damage to the fuel system.
Discontinue using gasohol of any kind if
drivability problems occur.Vehicle damage or driveability problems
may not be covered by the manufactur-
er’s warranty if they result from the use
of:
1. Gasohol containing more than 10%
ethanol.
2. Gasoline or gasohol containing methanol.
3. Leaded fuel or leaded gasohol.
✽ NOTICE
Never use gasohol which contains
methanol. Discontinue use of any gaso-
hol product which impairs drivability.
CAUTION
NEVER USE LEADED FUEL. The
use of leaded fuel i s detrimental to
the catalytic converter and will damage the engine control s ys-
tem’ s oxygen s ensor and affect
emission control.
Never add any fuel system cleaningagents to the fuel tank other thanwhat Kia has specified. (Con sult an
Authorized Kia Dealer for detail s.)

EMISSION CONTROL SYSTEM
The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty infor-
mation contained in the Warranty &
Consumer Information Manual in your
vehicle.
Vehicle modifications
This vehicle should not be modified.
Modification of your Kia could affect its
performance, safety or durability and
may even violate governmental safety
and emissions regulations.
In addition, damage or performance
problems resulting from any modification
may not be covered under warranty.
Engine exhaust gas precautions
(carbon monoxide)
• Carbon monoxide can be present withother exhaust fumes. Therefore, if you
smell exhaust fumes of any kind inside
your vehicle, have it inspected and
repaired immediately by an authorized
Kia dealer or other competent repair
shop. If you ever suspect exhaust
fumes are coming into your vehicle,
drive it only with all the windows fully
open. Have your vehicle checked and
repaired immediately. • Do not operate the engine in confined
or closed areas (such as garages) any
more than what is necessary to move
the vehicle in or out of the area.
• When the vehicle is stopped in an open area for more than a short time
with the engine running, adjust the
ventilation system (as needed) to draw
outside air into the vehicle.
• Never sit in a parked or stopped vehi- cle for any extended time with the
engine running.
• When the engine stalls or fails to start, excessive attempts to re-start the
engine may cause damage to the
emission control system.
WARNING
Engine exhaust gases contain car-
bon monoxide (CO). Though color-
less and odorless, it is dangerous
and could be lethal if inhaled.
Follow the instructions following to
avoid CO poisoning.

Operating precautions for catalyt-
ic converter s
Your vehicle is equipped with a catalytic
converter emission control device.
Therefore, the following precautions
must be observed:
• Use only UNLEADED FUEL for gaso-
line engine (unleaded).
• Do not operate the vehicle when there are signs of engine malfunction, such
as misfire or a noticeable loss of per-
formance.
• Do not misuse or abuse the engine. Examples of misuse are coasting with
the ignition off and descending steep
grades in gear with the ignition off. • Avoid driving with a very low fuel level.
If your run out of gasoline, it could
cause the engine to misfire and result
in excessive loading of the catalytic
converter.
• Do not operate the engine at high idle speed for extended periods (5 minutes
or more).
• Do not modify or tamper with any part of the engine or emission control sys-
tem. All inspections and adjustments
must be made by a qualified techni-
cian.
Failure to observe these precautions
could result in damage to the catalytic
converter and to your vehicle.
Additionally, such actions could void your
warranties.
WARNING- Fire
A hot exhaust system can ignite
flammable items under your vehi-
cle. Do not park the vehicle over or
near flammable object s,such as
dry grass, paper, leaves, etc.

Driving tips
BEFORE DRIVING
Before entering vehicle:
• Be sure that all windows, outside mir-ror(s), and outside lights are clean.
• Check the condition of the tires.
• Check under the vehicle for any sign of leaks.
• Be sure there are no obstacles behind you if you intend to back up.
Necessary inspections
Fluid levels, such as engine oil, engine
coolant, brake fluid, and washer fluid
should be checked on a regular basis,
with the exact interval depending on the
fluid. Further details are provided in
Section 7, Maintenance.
Before starting
• Close and lock all doors.
• Position the seat so that all controls are
easily reached.
• Adjust the inside and outside rearview mirrors.
• Be sure that all lights work.
• Check all gauges.
• Check the operation of warning lights when the ignition switch is turned to
the ON position.
• Release the parking brake and make sure the brake warning light goes out.
For safe operation, be sure you are famil-
iar with your vehicle and its equipment.WARNING- Driving under
the influence of alcohol or
drugs
Drinking and driving i s dangerous.
Drunk driving is the number one
contributor to the highway death
toll each year. Even a small amount
of alcohol will affect your reflexe s,
perceptions and judgement.
You are much more likely to have a
serious accident if you drink and
drive.
If you are drinking or taking drug s,
don’t drive. Do not ride with a driv-
er who has been drinking or taking
drugs. Choose a designated driver
or call a cab.
Driving while under the influence of
drugs i s as dangerous or more dan-
gerou s than driving drunk.

SUGGESTIONS FOR ECONOMICAL OPERATION
Your vehicle's fuel economy depends
mainly on your style of driving, where you
drive and when you drive.
Each of these factors affects how many
kilometers (miles) you can get from a liter
(gallon) of fuel. To operate your vehicle
as economically as possible, use the fol-
lowing driving suggestions to help save
money in both fuel and repairs:
• Avoid lengthy warm-up idling. Once theengine is running smoothly, begin driv-
ing. Remember, engine warm-up may
take a little longer on cold days.
• Save fuel by accelerating slowly after stopping.
• Keep the engine in tune and follow the recommended periodic maintenance
schedule. This will increase the life of
all parts and lower your operating
costs. • Do not use the air conditioner unnec-
essarily.
• Slow down when driving on rough roads.
• For longer tire life and better fuel econ- omy, always keep the tires inflated to
the recommended pressures.
• Maintain a safe distance from other vehicles to avoid sudden stops. This
will reduce wear on brake linings and
pads. Driving in such a way will also
save fuel because extra fuel is required
to accelerate back to driving speed.
• Do not carry unnecessary weight in the vehicle.
• Do not rest your foot on the brake pedal while driving. This can cause
needless wear, possible damage to the
brakes, and poor fuel economy.
• Improper wheel alignment results in faster tire wear and lower fuel econo-
my. • Open windows at high speeds can
reduce fuel economy.
• Fuel economy is less in crosswinds and headwinds. To help offset some of
this loss, slow down when driving in
these conditions.
Keeping a vehicle in good operating con-
dition is important both for economy and
safety. Therefore, have an authorized Kia
dealer perform scheduled inspections
and maintenance.
WARNING - Engine off dur-
ing motion
Never turn the engine off to coa st
down hills or anytime the vehicle i s
in motion. The power steering and
power brakes will not function with-
out the engine running. Ins tead,
downshift to an appropriate gear for
engine braking effect.

SPECIAL DRIVING CONDITIONS
Hazardous driving conditions
When hazardous driving conditions are
encountered such as water, snow, ice,
mud, sand, or similar hazards, follow
these suggestions:
• Drive cautiously and allow extra dis-
tance for braking.
• Avoid sudden movements in braking or steering.
• When braking, pump the brake pedal with a light up-and-down motion until
the vehicle is stopped.
✽ NOTICE
Do not pump the brake pedal on a vehi-
cle equipped with ABS.
• If stalled in snow, mud, or sand, use
second gear. Accelerate slowly to
avoid spinning the drive wheels.
• Use sand, rock salt, tire chains, or other non-slip material under the drive
wheels to provide traction when stalled
in ice, snow, or mud.Rocking the vehicle
If it is necessary to rock the vehicle to
free it from snow, sand, or mud, first turn
the steering wheel right and left to clear
the area around your front wheels. Then,
shift back and forth between R (Reverse)
and any forward gear in vehicles
equipped with an automatic transaxle. Do
not race the engine, and spin the wheels
as little as possible. If you are still stuck
after a few tries, have the vehicle pulled
out by a tow vehicle to avoid engine
overheating and possible damage to the
transaxle.
WARNING - Downshifting
Downs hifting with an automatic
transaxle, while driving on slippery
surfaces can cause an accident.
The sudden change in tire speed
could cause the tires to skid. Be
careful when downshifting on slip-
pery surfaces.

✽NOTICE
Prolonged rocking may cause engine
over-heating, transaxle damage or fail-
ure, and tire damage.
Driving at night
Because night driving presents more
hazards than driving in the daylight, here
are some important tips to remember:
• Slow down and keep more distance
between you and other vehicles, as it
may be more difficult to see at night,
especially in areas where there may
not be any street lights.
• Adjust your mirrors to reduce the glare from other driver's headlights.
• Keep your headlights clean and prop- erly aimed on vehicles not equipped
with the automatic headlight aiming
feature. Dirty or improperly aimed
headlights will make it much more diffi-
cult to see at night.
• Avoid staring directly at the headlights of oncoming vehicles. You could be
temporarily blinded, and it will take
several seconds for your eyes to read-
just to the darkness.
Driving in the rain
Rain and wet roads can make driving
dangerous, especially if you’re not pre-
pared for the slick pavement. Here are a
few things to consider when driving in the
rain:
• A heavy rainfall will make it harder tosee and will increase the distance
needed to stop your vehicle, so slow
down.
• Keep your windshield wiping equip- ment in good shape. Replace your
windshield wiper blades when they
show signs of streaking or missing
areas on the windshield.
• If your tires are not in good condition, making a quick stop on wet pavement
can cause a skid and possibly lead to
an accident. Be sure your tires are in
good shape.
• Turn on your headlights to make it eas- ier for others to see you.
• Driving too fast through large puddles can affect your brakes. If you must go
through puddles, try to drive through
them slowly.
• If you believe you may have gotten your brakes wet, apply them lightly
while driving until normal braking oper-
ation returns.
WARNING- Spinning tires
Do not spin the wheels,e specially
at speeds more than 56 km/h (35
mph). Spinning the wheel s at high
speeds when the vehicle is station-
ary could cause a tire to overheat,
explode and injure bystander s.

Driving tips
Winter driving
• We recommend that you carry emer-gency equipment, including tire chains,
a window scraper, windshield de-icer,
a bag of sand or salt, flares, a small
shovel and jumper cables.
• Make sure you have sufficient ethyl- ene-glycol coolant in the radiator.
• Check the battery condition and cables. Cold temperatures reduce the
capacity of any battery, so it must be in
excellent condition to provide enough
winter starting power.
• Make sure the engine oil viscosity is suitable for cold weather.
• Check the ignition system for loose connections and damage.
• Use antifreeze-formulated windshield washer fluid. (Do not use engine
coolant antifreeze.)
• Do not use the parking brake if it might freeze. When parking, shift to P (Park)
with an automatic transaxle and block
the rear wheels.
Snow tires
If you mount snow tires on your Kia,
make sure they are radial tires of the
same size and load range as the original
tires. Mount snow tires on all four wheels
to balance your vehicle’s handling in all
weather conditions. Keep in mind that the
traction provided by snow tires on dry
roads may not be as high as your vehi-
cle's original equipment tires. You should
drive cautiously even when the roads are
clear. Check with the tire dealer for max-
imum speed recommendations.
Do not install studded tires without firstchecking local, state and municipal regu- lations for possible restrictions againsttheir use.
Driving in flooded areas
Avoid driving through flooded areas
unless you are sure the water is no high-
er 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 several
times while the vehicle is moving slowly.
WARNING- Snow tire size
Snow tires should be equivalent in
size and type to the vehicle' s stan-
dard tires. Otherwise, the safety and
handling of your vehicle may be
adver sely affected.

HLA (Hydraulic Lash Adjuster)
noise
The engine HLA's keep the gap between
the valve and cam at zero regardless of
the valve expansion.
Occasionally, you may hear a temporary
or continuous sound (clatter) from the
engine when starting or idling. This noise
will usually go away by following a few
simple steps: If the temporary sound occurs when
starting a cold engine:
This is a normal condition. This sound
will disappear after the engine oil has
reached normal operating pressure.
If the sound occurs when starting the
engine after the engine has not been oper-
ated for more than 48 hours; or engine
has been cranked excessively:
This condition may be caused by oil
draining from the HLA's. This allows air to
enter the HLA causing insufficient lubri-
cating oil in the HLA. This will usually dis-
appear within 15 minutes with the engine
running at 2000~3000 rpm. If the sound
does not disappear, have the engine oil
pressure, engine lubrication system and
HLA's inspected by an Authorized Kia
Dealer.
CAUTION
Do not run the engine at more than
3000 rpm until the noi se goes away.
Damage to the HLA's could occur.
