Seat warmer (if equipped)
The seat warmers are provided to
warm the front seats during cold
weather. With the ignition switch in
the ON position, push either of the
switches to warm the driver's seat or
the front passenger's seat.
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, the
temperature 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 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.

Operation Tips
To keep dust or unpleasant fumes
from entering the vehicle through
the ventilation system, temporarily
set the air intake control to the
recirculated air position. Be sure to
return the control to the fresh air
position when the irritation has
passed to keep fresh air in the
vehicle. This will help keep the driv-
er alert and comfortable.
Air for the heating/cooling system is drawn in through the grilles just
ahead of the windshield. Care
should be taken that these are not
blocked by leaves, snow, ice or
other obstructions.
To prevent interior fog on the wind- shield, set the air intake control to
the fresh air position and fan speed
to the desired position, turn on the
air conditioning system, and adjust
the temperature control to desired
temperature.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.

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.

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.
