Non-operational conditions of
rear parking assist system
The rear parking assist system may
not operate properly when:
1. Moisture is frozen to the sensor. (It will
operate normally when the moisture
has been cleared.)
2. The sensor is covered with foreign matter, such as snow or water, or the
sensor cover is blocked. (It will operate
normally when the material is removed
or the sensor is no longer blocked.)
3. Driving on uneven road surfaces (unpaved roads, gravel, bumps, gradi-
ent).
4. Objects generating excessive noise (vehicle horns, loud motorcycle
engines, or truck air brakes) are within
range of the sensor.
5. Heavy rain or water spray exists.
6. Wireless transmitters or mobile phones are within range of the sensor.
7. The sensor is covered with snow.
8. Trailer towing The detecting range may decrease
when:
1. The sensor is stained with foreign mat-
ter such as snow or water. (The sens-
ing range will return to normal when
removed.)
2. Outside air temperature is extremely hot or cold.
The following objects may not be rec-
ognized by the sensor:
1. Sharp or slim objects such as ropes, chains or small poles.
2. Objects which tend to absorb the sen- sor frequency such as clothes, spongy
material or snow.
3. Undetectable objects smaller than 1 m (40 in.) in height and narrower than 14
cm (6 in.) in diameter.
Rear parking assist system pre-
cautions
The rear parking assist system maynot sound sequentially depending on
the speed and shapes of the objects
detected.
The rear parking assist system may malfunction if the vehicle bumper
height or sensor installation has been
modified or damaged. Any non-factory
installed equipment or accessories
may also interfere with the sensor per-
formance.
The sensor may not recognize objects less than 40 cm (15 in.) from the sen-
sor, or it may sense an incorrect dis-
tance. Use caution.
When the sensor is frozen or stained with snow, dirt, or water, the sensor
may be inoperative until the stains are
removed using a soft cloth.
Do not push, scratch or strike the sen- sor. Sensor damage could occur.

Battery saver function
The purpose of this feature is to pre-
vent the battery from being dis-
charged. The system automatically
turns off the parking lights when the
driver removes the ignition key (smart
key: turns off the engine) and opens
the driver-side door.
With this feature, the parking lights will be turned off automatically if the driver
parks on the side of road at night.
If necessary, to keep the lights on
when the ignition key is removed,
(smart key: turns off the engine) per-
form the following:
1) Open the driver-side door.
2) Turn the parking lights OFF and ON again using the light switch on the
steering column.
Headlight escort function
(if equipped)
The headlights (and/or taillights) will
remain on for approximately 20 minutes
after the ignition key is removed or turned
to the ACC or LOCK position. However, if
the driver’s door is opened and closed,
the headlights are turned off after 30 sec-
onds.
The headlights can be turned off by
pressing the lock button on the transmit-
ter (or smart key) twice or turning off the
light switch from the headlight or Auto
light position.
Headlight leveling device
(if equipped)
Automatic type
It is automatically adjusted the headlight
beam level according to the number of
the passengers and the loading weight in
the luggage area.
And it offers the proper headlight beam
under the various conditions.
LIGHTING
WARNING
If it is not working properly even
though your car is inclined back-
ward according to passenger's
posture, or the headlight beam is
irradiated to the high or low posi-
tion, have your vehicle inspected
by an authorized KIA dealer.
Don't attempt to inspect or replace
the wiring yourself to prevent mal-
function.
CAUTION
If the driver gets out of the vehicle
through other doors (except dri-ver's door), the battery saver func- tion does not operate and the head-light escort function does not turnoff automatically. Therefore, It caus- es the battery to be discharged. Inthis case, make sure to turn off thelamp before getting out of the vehi- cle.

2. Set the air intake control to the outside(fresh) air position.
3. Set the temperature control to the desired position.
4. Set the fan speed control to the desired speed.
5. If dehumidified heating is desired, turn the air conditioning system (if
equipped) on.
If the windshield fogs up, set the mode to the
,position. Operation Tips
To prevent 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 irrita-
tion has passed to keep fresh air in the
vehicle. This will help keep the driver
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 condi-
tioning system, and adjust the temper-
ature control to desired temperature.
Air conditioning (if equipped)
All KIA Air Conditioning Systems are
filled with environmentally friendly
R-134a refrigerant which does not dam-
age the ozone layer.
1. Start the engine. Push the air condi- tioning button.
2. Set the mode to the position.
3. Set the air intake control to the recir- culated air position. However, pro-
longed operation of the reticulated air
position will excessively dry the air. In
this case, change the air position.
4. Adjust the fan speed control and tem- perature 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.

✽
✽NOTICE
• While using the air conditioning sys-
tem, monitor the temperature gauge
closely while driving up hills or in
heavy traffic when outside tempera-
tures are high. Air conditioning sys-
tem operation may cause engine over-
heating. Continue to use the blower
fan but turn the air conditioning sys-
tem off if the temperature gauge indi-
cates engine overheating.
• While 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 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 vehi-
cle by operating the air conditioning
system.
During air conditioning system opera- tion, you may occasionally notice a
slight change in engine speed as the
air conditioning compressor cycles.
This is a normal system operation
characteristic.
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 puddling) on the ground
under the passenger side of the vehi-
cle. This is a normal system operation
characteristic. Operating the air conditioning system
in the recirculated air position provides
maximum cooling, however, 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 opera-
tion characteristic.
