facilitate carrying long items or to
increase the luggage capacity of the
vehicle.
To fold down the rear seatback
1. Set the front seatback to the
upright position and if necessary,
slide the front seat forward.
2. Lower the rear headrests to the
lowest position as above the pic-
ture.
WARNING - Folded
Seatback
The purpose of the fold-down
rear seatbacks is to allow you to
carry longer objects than could
not otherwise be accommodated.

on top of the folded down
seatback while the car is mov-
ing. This is not a proper seat-
ing position since no seat
belts are available for use.
To reduce the risk of injury
caused by sliding cargo within
the passenger compartment
of the vehicle, objects carried
on the folded down seatback
should not extend higher than
the top of the front seats.

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
All Kia Air Conditioning Systems are
filled with R-1234yf 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 out-
side air or recirculated air position.
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, set the mode
control to the MAX A/C position,
then set the fan speed control to
the highest speed.CAUTION - Excessive A/C
Use
When using the air conditioning
system, monitor the tempera-
ture gauge closely while driving
up hills or in heavy traffic when
outside temperatures are high.
Air conditioning system opera-
tion may cause engine over-
heating. Continue to use the
blower fan but turn the air con-
ditioning system off if the tem-
perature gauge indicates engine
overheating.
CAUTION
When opening the windows in
humid weather, air conditioning
may create water droplets
inside the vehicle. Since exces-
sive water droplets may cause
damage to electrical equipment,
air conditioning 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.
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; howev-
er, continual operation in this mode
may cause the air inside the vehi-
cle 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.
Automatic ventilation
The system automatically selects the
outside (fresh) air position when the
climate control system operates over
a certain period of time (5 minutes)
in low temperature with the recircu-
lated air position selected. (when
floor mode or bi-level mode)To cancel or reset the Automatic
Ventilation
When the air conditioning system is
on, select Face Level ( ) mode
and while pressing the A/C button,
press the air intake control button 5
times within 3 seconds.
When the automatic ventilation func-
tion is canceled, the indicator light
blinks 3 times at an interval of 0.5
seconds.
The air intake will be automatically
controlled to the fresh air position,
and the flow and air conditioning will
be automatically controlled.
When the automatic ventilation func-
tion is selected, the indicator light
blinks 6 times at an interval of 0.25
seconds.
The air intake will be automatically
controlled to the fresh air position,
and the flow and air conditioning will
be automatically controlled.
After the battery has been dis-
charged or separated, the automatic
ventilation function will be reset, so
please selected, according to you
preference.

For maximum defrosting, set the
temperature control to the extreme
right/hot position and the fan speed
control to the highest speed.
If warm air to the floor is desired
while defrosting or defogging, set
the mode to the floor-defrost posi-
tion.
Before driving, clear all snow and
ice from the windshield, rear win-
dow, outside rear view mirrors, and
all side windows.
Clear all snow and ice from the
hood and air inlet in the cowl grill to
improve heater and defroster effi-
ciency and to reduce the probabili-
ty of fogging up the inside of the
windshield.Automatic climate control
system
To defog inside windshield
1. Set the fan speed to the desired
position.
2. Select desired temperature.
3. Press the defroster button ( ).
4. The outside (fresh) air position will
be selected automatically and the
air conditioning will turn on accord-
ing to the detected ambient tem-
perature.
WINDSHIELD DEFROSTING AND DEFOGGING
WARNING - Windshield
heating
Do not use the or posi-
tion during cooling operation in
extremely humid weather. The
difference between the temper-
ature of the outside air and the
windshield could cause the
outer surface of the windshield
to fog up, causing loss of visi-
bility. If this occurs, set the
mode selection to the posi-
tion and fan speed control to
the lower speed.

To hold the vehicle on a hill use the
foot brake or the parking brake. If
the vehicle is held by applying the
accelerator pedal on a hill the
clutch and transmission will be
overheated resulting in damage.
At this time, a warning message
(“Steep grade! Press brake pedal”)
will appear on the LCD display.
If the clutch becomes overheated
by excessive use of the clutch to
hold on a hill, you may notice a
shudder feeling and a blinking dis-
play on the instrument cluster.
When this occurs, the clutch is dis-
abled until the clutch cools to nor-
mal temperatures. If this occurs,
pull over to a safe location, shift
into P (Park) and apply the foot
brake for a certain time on the LCD
warning until it disappears.
If the LCD warning is active, the
foot brake must be applied.
Ignoring the warnings can lead to
damage to the transmission. If the display continues to blink, for
your safety, we recommend that you
contact an authorized Kia dealer.
Under certain conditions such as
repeated launch on steep grades,
the clutch in the transmission could
overheat.
When the clutch is overheated, the
safe protection mode engages. If
the safe protection mode engages,
the gear position indicator on the
cluster blinks with a chime sound.
At this time, one of these warning
messages (“Transmission temp. is
high! Stop safely”, “Trans hot! Park
with engine on”, “Trans Cooling.
Remain parked for 00 min.”, “Trans
Cooled. Resume driving”) will
appear on the LCD display and driv-
ing may not be smooth.
If you ignore this warning, the driv-
ing condition may become worse.
To return the normal driving condi-
tion, stop the vehicle and apply the
foot brake for a few minutes before
driving off. Gear shifts may be more notice-
able than a conventional automatic
transmission. This is a normal
characteristic of this type of dual
clutch transmission.
During the first 1,500 km (1,000
miles), you may feel that the vehi-
cle may not be smooth when accel-
erating at low speed. During this
break-in period, the shift quality
and performance of your new vehi-
cle is continuously optimized.
Always come to a complete stop
before shifting into D (Drive) or R
(Reverse).
Do not put the shift lever in N
(Neutral) while driving.

Use high quality ethylene gly-
col coolant
Your vehicle is delivered with high
quality ethylene glycol coolant in the
cooling system. It is the only type of
coolant that should be used because
it helps prevent corrosion in the cool-
ing system, lubricates the water
pump and prevents freezing. Be sure
to replace or replenish your coolant
in accordance with the maintenance
schedule in chapter 8. Before winter,
have your coolant tested to assure
that its freezing point is sufficient for
the temperatures anticipated during
the winter.
Check battery and cables
Winter puts additional burdens on
the battery system. Visually inspect
the battery and cables as described
in chapter 8. The level of charge in
your battery can be checked by an
authorized Kia dealer or a service
station.
Change to "winter weight" oil
if necessary
In some climates it is recommended
that a lower viscosity "winter weight"
oil be used during cold weather. See
chapter 9 for recommendations. If
you aren't sure what weight oil you
should use, consult an authorized
Kia dealer.
Check spark plugs and ignition
system
Inspect your spark plugs as
described in chapter 8 and replace
them if necessary. Also check all
ignition wiring and components to be
sure they are not cracked, worn or
damaged in any way.
To keep locks from freezing
To keep the locks from freezing,
squirt an approved de-icer fluid or
glycerine into the key opening. If a
lock is covered with ice, squirt it with
an approved de-icing fluid to remove
the ice. If the lock is frozen internally,
you may be able to thaw it out by
using a heated key. Handle the heat-
ed key with care to avoid injury.
Use approved window washer
anti-freeze in system
To keep the water in the window
washer system from freezing, add an
approved window washer anti-freeze
solution in accordance with instruc-
tions on the container. Window wash-
er anti-freeze is available from an
authorized Kia dealer and most auto
parts outlets. Do not use engine
coolant or other types of anti-freeze
as these may damage the paint fin-
ish.

What to do in an emergency
IF THE ENGINE OVERHEATS
If your temperature gauge indicates
overheating, you will experience a
loss of power, or hear loud pinging or
knocking, the engine is probably too
hot. If this happens, you should:
1. Turn on the emergency warning
flasher and stop in a safe place.
Move the shift lever to P (Park)
and engage the parking brake.
2. If hot steam does not come out
from the engine room, carefully
open the engine room and check
whether the water pump connec-
tor is properly engaged. If the con-
nector is not properly engaged,
stop the engine immediately and
properly engage the connector.
Then, turn the engine on.
3. Turn on the air conditioner.4. If the “HEV Warning” light turns on
in the driver instrument cluster, or
engine coolant or hot steam emits
from the engine coolant filler, stop
the engine immediately. Then, call
the nearest authorized Kia dealer
for assistance. If the “Engine
Warning” light remains illuminated
or the engine coolant is not flowing
out, keep the engine running.
Open the engine hood for ventila-
tion to help cool down the engine.5. Check whether the engine coolant
temperature is low enough by
checking its temperature. If the
engine coolant level is low, please
check the connecting parts
between the radiator hose, heater
hose, and water pump for any signs
of leakage. When there is no sign of
leakage, please refill the engine
coolant. If causes and signs of
engine overheating such as warn-
ing light illumination, engine coolant
leakage, or cooling fan malfunction
are found, stop the vehicle the ear-
liest. Then, call the nearest author-
ized Kia dealer for assistance.
WARNING- Under the
Hood
While the engine is running,
keep hair, hands and clothing
away from moving parts such
as the fan and drive belts to pre-
vent injury.
WARNING- Radiator Cap
Do not remove the
radiator cap when the
engine is hot. This
can allow coolant to
blow out of the open-
ing and cause seri-
ous burns.
