Safety features of your vehicle
During mild weather or under condi-
tions where the operation of the seat
warmer is not needed, keep the
switches in the OFF position.
With the seat warmer switch in the
ON position, the heating system in
the seat turns off or on automatically
depending on the seat temperature.
Each time you push the button, thetemperature setting of the seat is
changed as follows :
When pressing the switch for more than 1.5 seconds with the seat
warmer operating, the seat warmer
will turn OFF.
The seat warmer defaults to the OFF position whenever the engine
start/stop button (the ignition
switch) is turned on.CAUTION - Seat damage
When cleaning the seats, do not use an organic solventsuch as paint thinner, ben-zene, alcohol and gasoline.Doing so may damage the sur-face of the heater or seats.
To prevent overheating the seat warmer, do not place any-thing on the seats that insu-lates against heat, such asblankets, cushions or seatcovers while the seat warmeris in operation.
Do not place heavy or sharp objects on seats equippedwith seat warmers. Damage tothe seat warming componentscould occur.
WARNING- Seat warmer
burns
Passengers should use extreme
caution when using seat warm-
ers due to the possibility of
excess heating or burns. The
seat warmer may cause burns
even at low temperatures, espe-
cially if used for long periods of
time. The occupants must be
able to feel if the seat is becom-
ing too warm and to turn the
seat warmer off.

Engine coolant temperature gauge
This gauge shows the temperature
of the engine coolant when the igni-
tion switch is ON.
Do not continue driving with an over-
heated engine. If your vehicle over-
heats, refer to "If the engine over-
heats" in chapter 6.
If the gauge pointer moves beyond
the normal range area toward the "H"
position, it indicates overheating that
may damage the engine.
Fuel gauge
The fuel gauge indicates the approx-
imate amount of fuel remaining in the
fuel tank. The fuel tank capacity is
given in chapter 8. The fuel gauge is
supplemented by a low fuel warning
light, which will illuminate when the
fuel tank is nearly empty.
On inclines or curves, the fuel gauge
pointer may fluctuate or the low fuel
warning light may come on earlier
than usual due to the movement of
fuel in the tank.
WARNING - Fuel gauge
Stop and obtain additional fuel
as soon as possible after the
warning light comes on or when
the gauge indicator comes
close to the E level. Running out
of fuel can expose vehicle occu-
pants to danger.
CAUTION - Low fuel
Avoid driving with extremely
low fuel level. Running out offuel could cause the engine tomisfire, damaging the catalyticconverter.OTF044057

Air conditioning system operation tips
If the vehicle has been parked indirect sunlight 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 or humid
days, decrease the humidity inside
the vehicle by operating the air
conditioning system.
During air conditioning system operation, you may occasionally
notice a slight change in engine
speed as the air conditioning com-
pressor cycles. This is a normal
system operation characteristic.
Use the air conditioning system every month only for a few minutes
to ensure maximum system per-
formance.
When using the air conditioning system, you may notice clear water
dripping (or even puddling) on the
ground under the passenger side
of the vehicle. This is a normal sys-
tem operation characteristic. Operating the air conditioning sys-
tem in the recirculated air position
provides maximum cooling, how-
ever, continual operation in this
mode may cause the air inside the
vehicle to become stale.
During cooling operation, you may occasionally notice a misty air flow
because of rapid cooling and
humid air intake. This is a normal
system operation characteristic.CAUTION - Excessive
AC
While using the air conditioningsystem, monitor the tempera-ture gauge closely while drivingup hills or in heavy traffic whenoutside temperatures are high.
Air conditioning system opera-tion may cause engine over-heating and potential enginedamage. If the temperaturegauge indicates overheating,turn off the a/c, safely stop thevehicle, turn off the engine andcontact your authorized Kiadealer.

Air conditioning
Kia Air Conditioning Systems are
filled with environmentally friendly R-
134a refrigerant.
1. Start the engine. Press the air con-
ditioning button.
2. Set the mode to the position.
3. Set the air intake control to the outside air or recirculated air posi-
tion.
4. Adjust the fan speed control and temperature control to maintain
maximum comfort.
When maximum cooling is desired, set the temperature control to the
extreme left position, then set the
fan speed control to the highest
speed.
✽ ✽ NOTICE
• When using the air conditioning
system, monitor the temperature
gauge closely while driving up
hills or in heavy traffic when out-
side temperatures are high. Air
conditioning system operation
may cause engine overheating.
Continue to use the blower fan but
turn the air conditioning system
off if the temperature gauge indi-
cates engine overheating.
• When opening the windows in humid weather air conditioning
may create water droplets inside
the vehicle. Since excessive water
droplets may cause damage to
electrical equipment, air condi-
tioning should only be used with
the windows closed.
Air conditioning system operation tips
If the vehicle has been parked in
direct sunlight 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 or humid
days, decrease the humidity inside
the vehicle by operating the air
conditioning system.
During air conditioning system operation, you may occasionally
notice a slight change in engine
speed as the air conditioning com-
pressor cycles. This is a normal
system operation characteristic.
Use the air conditioning system every month only for a few minutes
to ensure maximum system per-
formance.

Driving your vehicle
WARNING - Fire risk
When you intend to park or stop
the vehicle with the engine on,
be careful not to depress the
accelerator pedal for a long
period of time. It may overheat
the engine or exhaust system
and cause a fire.WARNING - Driving while intoxicated
Do not drive while intoxicated.
Drinking and driving is danger-
ous. Even a small amount of
alcohol will affect your reflexes,
perceptions and judgment.
Driving while under the influ-
ence of drugs is as dangerous
as or more dangerous than driv-
ing drunk.
WARNING - Loose object
Securely store items in your
vehicle. When you make a sud-
den stop or turn the steering
wheel rapidly, loose objects
may drop on the floor and it
could interfere with the opera-
tion of the foot pedals, possibly
causing an accident.

Power brakes
Your vehicle has power-assisted
brakes that adjust automatically
through normal usage.
In the event that the power-assisted
brakes lose power because of a
stalled engine or some other reason,
you can still stop your vehicle by
applying greater force to the brake
pedal than you normally would. The
stopping distance, however, will be
longer.
When the engine is not running, the
reserve brake power is partially
depleted each time the brake pedal
is applied. Do not pump the brake
pedal when the power assist has
been interrupted.
Pump the brake pedal only when
necessary to maintain steering con-
trol on slippery surfaces. Wet brakes may impair the vehicle’s
ability to safely slow down; the vehi-
cle may also pull to one side when
the brakes are applied. Applying the
brakes lightly will indicate whether
they have been affected in this way.
To dry the brakes, apply them lightly
while maintaining a safe forward
speed until brake performance
returns to normal.
BRAKE SYSTEM
WARNING - Steep hill
braking
Avoid continuous application of
the brakes when descending a
long or steep hill by shifting to a
lower gear. Continuous brake
application will cause the
brakes to overheat and could
result in a temporary loss of
braking performance.
CAUTION - Brake pedal
Do not drive with your foot rest- ing on the brake pedal. This willcreate abnormally high braketemperatures which can causeexcessive brake lining and padwear.

Good braking practices
Check to be sure the parking brake
is not engaged and that the park-
ing brake indicator light is out
before driving away.
Driving through water may get the brakes wet. They can also get wet
when the vehicle is washed. Wet
brakes can be dangerous! Your
vehicle will not stop as quickly if the
brakes are wet. Wet brakes may
cause the vehicle to pull to one
side.
To dry the brakes, apply the brakes
lightly until the braking action
returns to normal, taking care to
keep the vehicle under control at
all times. If the braking action does
not return to normal, stop as soon
as it is safe to do so and call an
authorized Kia dealer for assis-
tance.
Don't coast down hills with the vehicle out of gear. This is extreme-
ly hazardous. Keep the vehicle in
gear at all times, use the brakes to
slow down, then shift to a lower
gear so that engine braking will
help you maintain a safe speed. Don't "ride" the brake pedal.
Resting your foot on the brake
pedal while driving can be danger-
ous because the brakes might
overheat and lose their effective-
ness. It also increases the wear of
the brake components.
If a tire goes flat while you are driv- ing, apply the brakes gently and
keep the vehicle pointed straight
ahead while you slow down. When
you are moving slowly enough for it
to be safe to do so, pull off the road
and stop in a safe place.
If your vehicle is equipped with an automatic transaxle, don't let your
vehicle creep forward. To avoid
creeping forward, keep your foot
firmly on the brake pedal when the
vehicle is stopped.
Be cautious when parking on a hill. Firmly engage the parking brake
and place the shift lever in P (auto-
matic transaxle). If your vehicle is
facing downhill, turn the front
wheels into the curb to help keep
the vehicle from rolling. If your vehicle is facing uphill, turn
the front wheels away from the
curb to help keep the vehicle from
rolling. If there is no curb or if it is
required by other conditions to
keep the vehicle from rolling, block
the wheels.
Under some conditions your park- ing brake can freeze in the
engaged position. This is most like-
ly to happen when there is an
accumulation of snow or ice
around or near the rear brakes or if
the brakes are wet. If there is a risk
that the parking brake may freeze,
apply it only temporarily while you
put the shift lever in P (automatic
transaxle) and block the rear
wheels so the vehicle cannot roll.
Then release the parking brake.
Do not hold the vehicle on the upgrade with the accelerator
pedal. This can cause the transaxle
to overheat. Always use the brake
pedal or parking brake.

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 miles (kilometers) you can get
from a gallon (liter) of fuel. To operate
your vehicle as economically as pos-
sible, use the following driving sug-
gestions to help save money in both
fuel and repairs:
Drive smoothly. Accelerate at a
moderate rate. Don't make "jack-
rabbit" starts or full-throttle shifts
and maintain a steady cruising
speed. Don't race between stop-
lights. Try to adjust your speed to
the traffic so you don't have to
change speeds unnecessarily.
Avoid heavy traffic whenever pos-
sible. Always maintain a safe dis-
tance from other vehicles so you
can avoid unnecessary braking.
This also reduces brake wear.
Drive at a moderate speed. The faster you drive, the more fuel your
vehicle uses. Driving at a moderate
speed, especially on the highway,
is one of the most effective ways to
reduce fuel consumption. Don't "ride" the brake pedal. This
can increase fuel consumption and
also increase wear on these com-
ponents. In addition, driving with
your foot resting on the brake pedal
may cause the brakes to overheat,
which reduces their effectiveness
and may lead to more serious con-
sequences.
Take care of your tires. Keep them inflated to the recommended pres-
sure. Incorrect inflation, either too
much or too little, results in unnec-
essary tire wear. Check the tire
pressures at least once a month.
Be sure that the wheels are aligned correctly. Improper align-
ment can result from hitting curbs
or driving too fast over irregular
surfaces. Poor alignment causes
faster tire wear and may also result
in other problems as well as
greater fuel consumption. Keep your vehicle in good condi-
tion. For better fuel economy and
reduced maintenance costs, main-
tain your vehicle in accordance
with the maintenance schedule in
chapter 7. If you drive your vehicle
in severe conditions, more frequent
maintenance is required (see
chapter 7 for details).
Keep your vehicle clean. For maxi- mum service, your vehicle should
be kept clean and free of corrosive
materials. It is especially important
that mud, dirt, ice, etc. not be
allowed to accumulate on the
underside of the vehicle. This extra
weight can result in increased fuel
consumption and also contribute to
corrosion.
Travel lightly. Don't carry unneces- sary weight in your vehicle. Weight
reduces fuel economy.
Don't let the engine idle longer than necessary. If you are waiting
(and not in traffic), turn off your
engine and restart only when
you're ready to go.
